How to disable bells all over the place...

To turn off that annoying flash (that lags your session) in vim:

In .vimrc


set vb t_vb= " Turn off visual bell


General beeps...

In .inputrc


set bell-style none


In ~/.bash_profile (or /etc/profile or .bashrc or somewhere)


setterm -blength 0


In X Window:


$ xset b off


To turn it on again use:


$ xset b on


For less

In ~/.bash_profile:


export LESS="-q"



sh -x try.sh 2>&1 | sed "s/^+ \(.*\)$/\n$ <b>\1<\/b>/g;"


The number of lines options with head and tail do not have to be negative...

After 15 years of using head and tail (and wondering why they are encourage the use of the "extra" '-n' option now!) a question just occurred to me...

"What if I don't know how many lines I want to see with tail, I just know I want to skip the first X lines...?"

The logical opposite of:

tail -X FILENAME

would of course be:

tail +Y FILENAME

Which (thanks to Unix being so logical) naturally works!

You wouldn't really want to use it without a -n in front because +NUM would more likely be a valid file name than a switch, so you do get a warning:


$ tail +20 FILENAME
tail: Warning: "+number" syntax is deprecated, please use "-n +number"


and head just barfs:


$ head +20 FILENAME
head: cannot open `+20' for reading: No such file or directory


So use:


$ tail -n +$SKIP FILENAME


Given the file:


$ seq 1 5 > FILENAME
$ cat FILENAME
1
2
3
4
5


Let's unit test...


$ head +2 FILENAME
head: cannot open `+2' for reading: No such file or directory
==> FILENAME <==
1
2
3
4
5


means: "head the files '+2' and 'FILENAME'"


$ head -2 FILENAME
1
2

$ head -n 2 FILENAME
1
2

$ head -n +2 FILENAME
1
2


all mean: "show the first 2 lines of FILENAME"


$ head -n -2 FILENAME
1
2
3


means "show all BUT the last 2 lines of FILENAME"


$ tail +2 FILENAME
tail: Warning: "+number" syntax is deprecated, please use "-n +number"
2
3
4
5


means "I'm being too lazy to use -n, but show me FILENAME from line 2 down"


$ tail -2 FILENAME
4
5

$ tail -n 2 FILENAME
4
5

$ tail -n -2 FILENAME
4
5


mean "Show me the last 2 lines of FILENAME"


$ tail -n +2 FILENAME
2
3
4
5


means "Show me FILENAME from line 2 down"

:%g/^sometext,/ d

search range (all lines) : %
beginning with "sometext,
execute the Ex cmd "d" ; delete the line

People that call it V I instead of "vie"...

...probably don't need a "vi quick reference guide/cheatsheet" anyway.

For a long time I've done things like:


for FILE in $(find * -type f -exec grep -l "$STRING" {} \;)
do
echo -n "$FILE"
grep -n "$STRING" $FILE
done


to get both the filename and the string it's matching on because there's no "name plus match" flag for grep... you either have -l or -n but not together...

I had a brainwave just now...

If you give grep more than one file to grep in - it tells you which file it found the match in... so how about:


$ find * -type f -exec grep -n $STRING {} /dev/null \;
path/to/the/FILE:12:I found $STRING on line 12!


If you can't be bothered typing, it can be any valid filename instead of /dev/null - i.e.:


grep -n $STRING {} /
grep -n $STRING {} .
grep -n $STRING {} *


I just figured /dev/null should hopefully have the least overhead to stat.

Be careful you don't give it an invalid filename or you'll get an error for each file the find finds!


$ find * -type f -exec grep STRING {} no_such_file \;
grep: no_such_file: No such file or directory
grep: no_such_file: No such file or directory
grep: no_such_file: No such file or directory
grep: no_such_file: No such file or directory
grep: no_such_file: No such file or directory


Hold is a status flag which tells apt (or aptitude) not to automatically upgrade a package.
To hold a package, 'echo pkgname +hold|dpkg --set-selections'
or 'aptitude hold package'
or use = in aptitude's curses interface.
You can ignore a hold by using apt-get install foopkg; or by using ++ in aptitude's curses interface.
[Note that this is *NOT* the same as packages which have been "held back" for dependency reasons.]

Snapshots is an archive that contains all Debian packages uploaded since 2002,
including those removed from the official archives because they were very buggy, unusable, broken, vulnerable or in some way undistributable.
Much of 2004 was lost because of harddisk problems.
See http://snapshot.debian.net/ for more information.

e.g.

Simplified:

If you want to join images side by side:

[ AA.jpg ][ AB.jpg ][ AC.jpg ]

use:


convert +append AA.jpg AB.jpg AC.jpg row_A.png


NB: If they're not photos, you'll want the output to be PNG so it's not lossy.

When you want to join the rows the +append becomes -append like so:

[ row_A.png ]
[ row_B.png ]
[ row_C.png ]


convert -append row_A.png row_B.png row_C.png all_rows.png


It's amazing how many different approaches to doing this you can find on the web.

Some of them are really tortured and inefficient!

These are the tightest two I've found:

#!/usr/bin/perl
#
#
#
use warnings;
use strict;

my $time = time % 86400;

#
# http://www.perlmonks.org/?node_id=101511
#
printf "%02d:%02d:%02d\n",(gmtime $time)[2,1,0];

#
# http://www.perlmonks.org/?node_id=101548
#
printf "%02d:%02d:%02d\n", ($time/3600)%24, ($time/60)%60, $time%60;

To convert the other way, an easy way is to use POSIX mktime:

#!/usr/bin/perl

use warnings;
use strict;

use POSIX qw(mktime);

my $day = "2008-05-28";
my ($d_year, $d_mon, $d_mday) = split /-/, $day;

my $secs = mktime(0, 0, 0, $d_mday, $d_mon-1, $d_year-1900);

If you need to see the contents of a function in ksh...


$ typeset -f [FUNCTION_NAME]


if you do typeset -f by itself it will list all of the defined functions.

When getting set up to share my Linux X desktop, I found to my temporary confusion, that unlike vncserver on Windows, which of course shares your existing desktop, the vncserver program for X is designed to start a new instance of an X server (possibly even blind to the person on the machine) and share *that* rather sharing your existing desktop, which is probably what you usually need to do!

To share your existing X desktop via VNC requires another tool called x0vncserver.

As far as I know this is only available with vnc4 (realvnc) and not with tightvnc.

To share my desktop, the first thing I needed to do was to create a password file for the incoming user to authenticate against:


$ vncpasswd .vnc/passwd
Password:
Verify:


The .vnc directory didn't need to exist already, it creates it for you.


$ ll .vnc/
total 12
drwxr-xr-x 2 john john 4096 Mar 20 15:28 .
drwxr-xr-x 52 john john 4096 Mar 20 15:28 ..
-rw------- 1 john john 8 Mar 20 15:28 passwd


It only seems to use the first 8 characters, and then saves that as obfuscated binary data.

Once you have the password file you can launch x0vncserver against it:


$ x0vncserver PasswordFile=.vnc/passwd

Thu Mar 20 15:33:32 2008
main: XTest extension present - version 2.2
main: Listening on port 5900


and it is ready to accept incoming connections :o)

If the incoming user is using tightvnc or another client that does not support the vnc4 protocol extensions, then you need to tell it to run in vnc3.3 compatibility mode:


$ x0vncserver Protocol3.3 PasswordFile=.vnc/passwd


You can also get usage help from x0vncserver by running it with any args it doesn't understand:


$ x0vncserver .


I found out why my machine was shutting down at low battery and why I couldn't get it to suspend to disk instead...

Fixed now :o)

You need to look at these files:


/etc/powersave/battery


I changed these values:


BATTERY_WARNING="10"
BATTERY_LOW="5"
BATTERY_CRITICAL="0"


And in:


/etc/powersave/events


I now have these:


EVENT_BATTERY_LOW="notify"
EVENT_BATTERY_CRITICAL="notify john_suspend_to_disk"


NB: I put john in the name so it would stick out like a sore thumb when I do a diff if dpkg ever asks me about changed config files on an upgrade and I'll know it's my own modification, and so it didn't conflict with or get overwritten by a provided script.

I created my own script to handle this:


/usr/lib/powersave/scripts/john_suspend_to_disk


which just has:


#!/bin/sh
#
#
#

sleep 10

/usr/sbin/s2disk

#
# You could use:
# echo -n disk > /sys/power/state
#


And I installed uswsusp which provides /usr/sbin/s2disk

Oh... I also set up a shell function to protect it, because I found I accidentally scrolled back through my shell history and hit enter on s2disk a couple of times ;o)


# type s2disk
s2disk is a function


I put this in my .bashrc:


s2disk ()
{
echo -e "Confirm you want to suspend: \c";
read OK;
if [ "$OK" = "y" ]; then
/usr/sbin/s2disk;
fi
}


What I *would* also like to add is a notify when the battery reaches 100% so I know to unplug my charger - I understand it's much better for the longevity of your battery if you don't leave it plugged in on full charge all the time and instead allow it to do full flat-charged-flat power cycles. I have a couple of laptops with useless batteries due to them having been left plugged in and running 24x7 for months or years on end - my Linux boxes rarely get shut down.

In an ideal world I'd like some device that plugged in between the charger plug and the laptop which I could drive from the OS to physically break the power connection when the battery gets to 100% - and not to reconnect it again until it's back to 0% (yes, I find with my reasonably new battery I can actually keep running it quite a while after it reaches "0%" - obviously 0% isn't dead flat - it's an arbitrary level set to give you a safety margin and still work when your battery is getting a bit knackered due to age.)

I downloaded VMware-player-2.0.2-59824.i386.rpm and converted it with alien.


# alien VMware-player-2.0.2-59824.i386.rpm --scripts


I had installed it before, then removed it to install vmware-server (because vmware-server complained that installing it caused file conflicts with vmplayer) and later removed vmware-server again and reinstalled vmplayer.

The bits left behind by vmware-server seem to break it...
The nice thing would be to find them and remove them, but I found a workaround.

When I first tried to install the player again I got error messages from some of the install scripts:


dpkg: error processing vmwareplayer_2.0.2-59825_i386.deb (--install):
subprocess pre-installation script returned error exit status 1
/var/lib/dpkg/tmp.ci/postrm: line 25: [: abort-install: integer expression expected
Errors were encountered while processing:
vmwareplayer_2.0.2-59825_i386.deb


So I backed up the deb file and built a copy of it with no scripts using:


# alien VMware-player-2.0.2-59824.i386.rpm


(and renamed that vmwareplayer_2.0.2-59825_i386.deb.no_scripts)

I was able to install it, but when I tried to run the player I found more hangovers of having had vmware-server installed:


$ vmplayer
Unable to load image-loading module: /build/mts/release/bora-59824/bora/build/release/ws/vmui/../libdir/libconf/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so: /build/mts/release/bora-59824/bora/build/release/ws/vmui/../libdir/libconf/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so: cannot open shared object file: No such file or directory


I made sure it was there:


$ locate libpixbufloader-png.so
/usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so


Eventually I found the solution was to run:


# /usr/bin/vmware-config.pl


but... that failed:


# /usr/bin/vmware-config.pl
Making sure services for VMware Player are stopped.

sh: /etc/init.d/vmware: No such file or directory
sh: /etc/init.d/vmware: No such file or directory
Unable to stop services for VMware Player

Execution aborted.



OK, so fake it:

Make a copy of /etc/init.d/vmware containing:


#!/bin/bash

echo $1


then:


# chmod +x /etc/init.d/vmware


Now run the config again:


# /usr/bin/vmware-config.pl
Making sure services for VMware Player are stopped.

status
stop

Configuring fallback GTK+ 2.4 libraries.

In which directory do you want to install the theme icons?
[/usr/share/icons]
...


and go through the rest of the config.

After this (if you have your correct compiler etc installed, you should find that vmplayer will start happily)

Once that works you will find you can now go back and over-install the copy of vmwareplayer_2.0.2-59825_i386.deb that DOES have scripts without it erroring, so you get your correct startup scripts etc...

Once you've reinstalled it you will again need to run


# /usr/bin/vmware-config.pl


one more time otherwise trying to run vmplayer will give you:


$ vmplayer
vmware is installed, but it has not been (correctly) configured
for this system. To (re-)configure it, invoke the following command:
/usr/bin/vmware-config.pl.

And trying it out...:

Read existing settings (recursively):

$ gconftool-2 -R /desktop/gnome/url-handlers

Backup settings to a file in case you want to roll back:

$ gconftool-2 -R /desktop/gnome/url-handlers > ~/.gconf/desktop/gnome/url-handlers.default

Get existing setting and type:

$ gconftool-2 -T -g /desktop/gnome/url-handlers/http/command

Set new setting and type

$ gconftool-2 -t string -s /desktop/gnome/url-handlers/http/command "x-www-browser %s"

From
here:

The VMWare Player list of "Recent Virtual Machines" is stored in the file
[drive]:\Documents and Settings\[user]\Application Data\VMWare\preferences.ini

At the bottom of the file, there are entries like (where X is a sequential number):

pref.mruVMX.filename = "..."
pref.mruVMX.displayname = "..."

You can edit the entries here then save the file & start VMWare Player to see the changes. (VMWare Player saves its settings on exit, so will need to be closed before you make the changes, or they will be overwritten.)

On an IBM Thinkpad T43 the Debian install refused to install grub or LILO.

When I tried to run it from the command line:

# grub-install hd0

it returned:

/dev/sda does not have any corresponding BIOS drive.

I tried changing the partition sizes so that they ended on cylinder boundaries - wondering if it was that - but it wasn't.

What I needed to do to fix it was to go into the BIOS settings and disable the legacy floppy support (I don't have a floppy drive, so don't use that)

The clue that tipped me off was lots of repeating errors in dmesg about fd0 each time I ran grub-install - and the fact that it would go away and wait for 10 or 15 minutes or more.

The things I had to do were:

# mkdir /boot/grub

# grub-install --no-floppy --recheck hd0

( this created /boot/grub/device.map )

# update-grub

(this created /boot/grub/menu.lst)

Like using VMWare Player, but can't find the image you want, or they're too big to download quickly?

This is how to get a working Debian box in VMWare without burning a CD:

I found:

http://whiletrue.nl/blog/?p=61

and:

http://www.sqlservercentral.com/articles/Miscellaneous/useisoimageswithoutburningtodisk/1369/

All you need to do is download the blank VMX from:

http://www.mediafire.com/?bnvmhcghmw3

Which was originally from http://www.boonzaaijer.com/files/BlankVMX.zip
but I don't want to leech their bandwidth by hot linking - all of 4KB ;-)

Unzip it into a folder (I use C:\VMWare\BlankVMX here)

Download the ISO image you want to install from - I'm using the latest NetInst ISO image here:

http://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/i386/iso-cd/

and save it (I save it as C:\VMWare\

Change the "Other Linux 2.6.x kernel.vmx" file:

Change the lines:

ide1:0.present = "TRUE"
ide1:0.fileName = "auto detect"
ide1:0.deviceType = "cdrom-raw"

To read something like:

ide1:0.present = "TRUE"
ide1:0.fileName = "C:\VMWare\debian-testing-i386-businesscard.iso"
ide1:0.deviceType = "cdrom-image"

Then run the .vmx file - it will boot and launch into your install image as if it had booted off a burned copy of the install CD.

I can't believe I didn't have a post about corkscrew already!

This is a great link:

http://www.mtu.net/~engstrom/ssh-proxy.php

install corkscrew via apt (synaptic/aptitude/apt-get whatever)

Edit your ~/.ssh/config file:


Host my.server my.other.server
    ProxyCommand corkscrew proxy.domain.com 8080 %h %p ~/.ssh/proxy_auth
    User remoteuser


in ~/.ssh/proxy_auth put:


username:password


It's a pain if you don't use the Host line because you have to comment the ProxyCommand line when you need to access a local machine (i.e. not through the proxy server)

Talking about proxies... a LONG time ago in another country (oots mon!) I used to use APS - I don't know if I'll need it again, but just in case, there it is.

I'm using the Debian Etch image from here with VMware Player

To get it to use a UK keyboard mapping I needed to do

loadkeys uk

for console, and

dpkg-reconfigure xserver-xorg

for X.

You also might need to start networking manually, and I exported my proxy details:


export http_proxy="http://proxy-server:port/"


Then ran synaptic - NICE - hadn't used it before.
Upgraded to a 686 kernel from the 486 one, stripped out all the gnome packages and put in fluxbox and wdm instead - it's much faster now.

I also did this

dhclient kept overwriting /etc/resolv.conf so I added this to /etc/dhcp/dhclient.conf


supersede domain-name-servers ns1-ip-address, ns2-ip-address;

as per one of the answers here: http://forums.debian.net/viewtopic.php?t=7239

The difference between:


my $var = EXPRESSION;


and


my ($var) = EXPRESSION;


is in whether EXPRESSION returns an array...

Of course in list context an array produces a list of the items in the array, but in scalar context it produces the number of items in the array...

By putting the parentheses around the scalar you are populating an array, and $var is asking for the first element of EXPRESSION if it returns a list, so:


#!/usr/bin/perl

use warnings;
use strict;

my @array = ('a', 'b', 'c');

my $var1 = @array;

my ($var2) = @array;

print "var1: [$var1]\nvar2: [$var2]\n";


returns:


var1: [3]
var2: [a]


Thus if your expression unexpectedly returns an array you at least get some useful value rather than a mysterious number. :-)

It's as simple as:


use strict;
use CGI ( );

my $cgi = new CGI;
print $cgi->header('text/plain');
print "DEBUG:\n", join('', map({"$_: [".$cgi->param($_)."]\n"} $cgi->param)), $/;

If you want to have a port listening on a machine just so another host can test connecting to it (e.g. you want to see whether your "Connection refused" message is caused by your socket application failing to serve, or if it is serving but the connection is being blocked by a firewall)...

First make sure that the application that would normally listen to that port is stopped, then run up netcat:

nc -l -p 1234

where 1234 is the port you want to listen on...

Now from the other host:

telnet hostname.domain.com 1234

where hostname.domain.com is the machine you're running netcat on.

This is a failure:

$ telnet hostname.domain.com 1234
Trying 10.11.12.13...
telnet: Unable to connect to remote host: Connection refused

This is a successful connection:

$ telnet hostname.domain.com
Trying 10.11.12.13...
Connected to hostname.domain.com (10.11.12.13).
Escape character is '^]'.

If you get a connection then the network probably isn't the problem...

Once you're connected you can then either use ^D (<Ctrl-d>) to get out, or use ^] (<Ctrl-]>) to get a telnet prompt, then type close:

$ telnet hostname.domain.com
Trying 10.11.12.13...

Escape character is '^]'.

To set the colour scheme permanently use:

colorscheme

In your .vimrc

(or color )

When in command mode type :help colorscheme for some help on this subject.

and:

syntax on

to make use of it.

(or:)


" have syntax highlighting in terminals which can display colours:
" > if has('syntax') && (&t_Co > 2)
syntax on
" > endif


I also have a post on toggling search highlighting...

If you just want to check from the command line:
bash --version
is OK, but that's not interactive - if you do that you're starting a new bash
which isn't necessarily the same version the current shell instance.

ksh:

In ksh you can display the version of the shell interactively by typing ^V

bash:

In bash you can do ^X^V (C-x C-v)

NB:
This works in set -o emacs.
If like me you prefer to live in the set -o vi world you may need to change to set -o emacs to check it and then back again.

There are also the BASH_VERSINFO array and BASH_VERSION variables

BASH_VERSINFO is immutable so you should be able to rely on it,
but BASH_VERSION could be set somewhere else so don't rely on it.

http://www.gnu.org/software/bash/manual/bashref.html#SEC110
has:

display-shell-version (C-x C-v)
Display version information about the current instance of Bash.

Problem:

You have found a cool Firefox theme on the web and want to download and try it,
but have never used another theme in Firefox before...

You download it and can install it OK, but now how the heck do you switch it on?

You go to Google and search and up comes spam in the form of a www.surveymonkey.com survey, ever so helpfully titled "Firefox Theme Tutorial" asking questions like:

1. Describe your experience with Firefox Themes.
-> I only use the default because I can't figure out how to change them.

2. Would you be interested in a detailed step by step how to guide for (*snip*) Firefox themes?

3. Would you be willing to pay for this guide?

4. How much would you be willing, if any, to pay for this guide?

Just damn cruel when that's the only thing that's in your face when you're looking for help!


OK, so you go to Help in Firefox and search for "theme"... you get:

Add-ons (extensions and themes)
Switching Themes
Using a High Contrast Theme


Hmm... "Switching Themes" is clearly the one I need... *click*:

Switching Themes

To switch between your installed themes, select the Themes panel, select the
theme of your choice, and click its Use Theme button. You need to
restart Firefox for changes to take effect.

Oh great... so I just need to select the Themes panel...
Click "Tools -> Options" - nope, not in there...
Check all the other menus:
File (didn't really think it would be there)
Edit (why would it be there?)
View (COULD be there... nope)
Tools (SHOULD be there, but can't see anything about themes)

the really helpful (NOT!) bit is that without scrolling backwards and forwards in the help page
there's no indication of where you FIND this "Themes panel"!

So after a bit more Googling I went to Intranet Exploder and tried out some of the YouTube tutorials...
(I don't install Flash in my Firefox - because I prefer not to have flash spam in pages...
the only time I start up IE is for something I *need* that uses Flash,
or for broken pages I have to use for work that don't validate and won't work in Firefox)

Yay! the answer \o/
http://youtube.com/watch?v=NvU4D-Buseo
http://youtube.com/watch?v=kykO8J0XA5c
http://youtube.com/watch?v=JjnCIRO9Jg4

I don't think I'd ever used YouTube to learn something technical before - but it certainly works!

In summary - the Themes are Add-ons - as are Extensions...
so the "Themes panel" is found under "Tools -> Add-ons"

I hadn't looked in there because I use Tools -> Add-ons quite regularly (for Extensions)
so didn't bother to look in there because I didn't remember noticing the Themes panel icon before.

I mounted a directory using sshfs:


sshfs user@host: /mnt/host


and found that while I could cd into it and ls it and do things with the files fine... Thunar (and Gentoo) didn't seem to know it existed.

I found the answer was to use -o allow_other when mounting the fuse-filesystem.


sshfs user@host: /mnt/host -o allow_other


all better :o)

I kept getting an error like this running apt-get update (I'm pretty sure it was immediately following adding a new line to /etc/apt/sources.list):


Get:5 http://ftp.debian.org etch/main Sources [1222kB]
79% [4 Packages bzip2 3911680] [5 Sources 50355/1222kB 4%] 25.2kB/s
46sbzip2: Data integrity error when decompressing.
Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

Err http://ftp.debian.org etch/main Packages
Sub-process bzip2 returned an error code (2)
Fetched 5616kB in 1m32s (60.6kB/s)
Reading package lists... Done


That wasn't my actual screen scrape - that's Brian May's off Google... because mine scrolled out of my history before I thought to grab it... but...

What I did was to comment out the sources in /etc/apt/sources.list that were erroring, then re-ran apt-get update again, and it worked OK.

After I'd finished the update I uncommented the lines and re-ran apt-get update and it worked fine.

...need to be declared:

You can do:

pkgchk -l -p /full/path/name

Or grep for the filename in /var/sadm/install/contents

If you put the Solaris CD in the drive on a Windows machine it doesn't read the CD filesystem correctly.

I needed SUNWi1cs and SUNWi15cs which are on Software CD 1 of 2 on Solaris 8
which are required for installing the Oracle 10.2.0.1 client...

On the Mac

I put the CD in the drive on the Mac

I then did a 'mount' to see where the CD was mounted:

hostname:~ john$ mount
/dev/disk0s10 on / (local, journaled)
devfs on /dev (local)
fdesc on /dev (union)
<volfs> on /.vol
automount -nsl [335] on /Network (automounted)
automount -fstab [345] on /automount/Servers (automounted)
automount -static [345] on /automount/static (automounted)
afp_2lYWSz0UiuFX000009000000-6.2e000003 on /Volumes/ast (nodev, nosuid, mounted by john)
afp_2lYWSz0UiuFX000009000000-5.2e000004 on /Volumes/EtherShare (nodev, nosuid, mounted by john)
/dev/disk1s0 on /Volumes/SOL_8_1000_SPARC (local, nodev, nosuid, read-only)

Change directory into the Product directory:

hostname:~ john$ cd /Volumes/SOL_8_1000_SPARC/Solaris_8/Product/

List the packages you need to see they're there...

hostname:/Volumes/SOL_8_1000_SPARC/Solaris_8/Product john$ ls -ld SUNWi1cs SUNWi15cs
drwxr-xr-x    5 root  daemon     2048 31 Aug  2000 SUNWi15cs
drwxr-xr-x    5 root  daemon     2048 31 Aug  2000 SUNWi1cs

Tar up the packages to a writable directory (i.e. outside the CD):

hostname:/Volumes/SOL_8_1000_SPARC/Solaris_8/Product john$ tar cvf ~/SUNWi15cs.tar SUNWi15cs
SUNWi15cs/

SUNWi1cs/reloc/usr/openwin/lib/
SUNWi1cs/reloc/usr/openwin/lib/locale/
SUNWi1cs/reloc/usr/openwin/lib/locale/iso8859-1/

Go to that directory and list the files:

hostname:/Volumes/SOL_8_1000_SPARC/Solaris_8/Product john$ cd
hostname:~ john$ ls -l SUNW*
-rw-r--r--   1 john  staff  30720 10 Nov 15:31 SUNWi15cs.tar
-rw-r--r--   1 john  staff  40960 10 Nov 15:31 SUNWi1cs.tar

Copy the files to the Solaris machine:

hostname:~ john$ scp *.tar solarisbox:
john@solarisbox's password:
SUNWi15cs.tar                                 100%   30KB   2.8MB/s   00:00
SUNWi1cs.tar                                  100%   40KB   3.5MB/s   00:00

Now on the Solaris machine...

Move the tars somewhere:

# mkdir packages
# mv SUNW*.tar packages/
# cd packages
# ls -l SUNW*.tar

In case it was the compiler version I rolled back to gcc 3.3.2
But with gcc 3.3.2 I got the same error.

This file I found on Google references SQLT_TIMESTAMP_LTZ:
http://ftp.emini.dk/pub/php/win32/dev/php_build/oci805/include/ocidfn.h

I found this file in:

(ORACLE)/rdbms/demo/ocidfn.h

I upgraded to 10.2.0.1 and that worked.
In trying to get it working with 8.1.5 I tried adding more directories to CFLAGS
This didn't work.
What did get it to compile was hacking dbdimp.c and adding:

#include 
#define SQLT_TIMESTAMP_LTZ             232        /* TIMESTAMP WITH LOCAL TZ */

but I think that's a bit of a nasty hack...

Take your image (maybe a screenshot)...

Select the part you want to highlight.
Duplicate the image layer.
do Select -> Invert
Double click on the forground colour to get the colour selection dialogue.
Type "c0c0c0" in the "HTML Notation" box.
Click OK in the colour selection dialogue.
Select the copy layer
Flood fill the bottom one with c0c0c0.
Select each layer in the layer dialogue and change the blending mode to multiply or to darken only (which ever looks best)

Sooo easy!!!

Reanamed Background Layer to Tux

Created a new "Background" layer and filled it with black.

Duplicated Tux layer

Moved "Tux copy" behind Tux

With Tux copy layer selected:

Did ^A changed fill to Whole Selection, filled with white.

Copied layer

Turned off "Keep Transparency"

Right-Click, and choose Filters->Blur->Gaussian Blur (IIR) (50x50)

Paste your white copy over it again.

Anchor pasted layer

Filters->Repeat Gaussian Blur

Paste white copy (rinse & repeat 4 or 5 times and the halo will grow)

If you do it without the paste the halo will not be so bright and will thin a bit.

UPDATE: This used to be about installing GAIM (later Pidgin) with Meanwhile support - Meanwhile (the Sametime plugin) is now built in to Pidgin so you don't need to install it seperately... so this is now about how to get spell checking with Pidgin.

Have to use Sametime at work and fed up with it crashing or closing windows and losing your conversation history with no log when you accidentally brush the [Esc] key???

Hey there chataholics, this could be just what you've been looking for!
Take a chunk of Pidgin (which you used to know as Gaim)
Mix in a good sized quantity of GTK+
Sprinkle with a small pinch of Aspell and presto, ready to serve!

Currently available for free from your local store:
pidgin 2.0.2
GTK+ 2.10.13 rev a
Aspell

NB: For Aspell this time I installed the full installer, then the English dictionary... it spell checks British spelling correctly.

This is the same image:

-rwx------ 1 gbr02703 mkpasswd   1823914 Oct 19 21:02 gimp.psd
-rwx------ 1 gbr02703 mkpasswd    983037 Oct 19 21:05 gimp.xcf

The XCF file is half the size of the PSD but still handles layers.
(I don't know what PSD can do that it can't - I'll have to read on that)

Irfanview did save the PSD as a smaller PNG than GIMP did...
but then when I opened the Irfanview PNG in GIMP and saved that as a new png
GIMP it made it even SMALLER than Irfanview had!

-rwx------ 1 gbr02703 mkpasswd  324875 Oct 19 21:02 gimp.png

The Adobe Reader download page only offers you to download a 521Kb installer stub which downloads the rest of the installation off the net.

That isn't great if you're behind a proxy server that it won't authenticate with!

I found this page which says that a full installer can be downloaded from here:

Don't you hate that when you do a search in vim and all the results are highlighted, but they're highlighted in such a colour scheme that you can't see what that text is anymore? (white on yellow anyone?) ...sometimes you want to turn it off in a hurry.

...toggling syntax highlighting:

I have this in my ~/.vimrc now:


:colorscheme johngh

"
" Have <F2> toggle search match highlighting and report the change:
"

nnoremap <F2> :set hls! hls?<CR>

"
" Define colors that are different enough to be noticeable
" and clear enough to be visible...
"
hi search guifg=LightBlue guibg=White " gvim
hi search ctermfg=LightBlue ctermbg=White " console/terminal vim


There are different ways to express this, I've used the shortest I've found here.
As far as I know they mean the same thing, but I've also seen/tried:


nnoremap \th :set invhls hls?<CR>


and...


map <F2> :set hlsearch!<CR>


I presume "!" is the same as "inv", and that it means "toggle/invert the value of..."

I presume "?" means "show the value of..."

Originally from TipID 14


" have \th ("toggle highlight") toggle highlighting of search matches, and
" report the change:
nnoremap \th :set invhls hls?<CR>


NB: the \th is entered literally as \+t+h

\(letters) is nice to use in vim for mapping things, because \ is not used otherwise.
It's nice to keep v free for on-the-fly mappings...
<F2> is free, so let's use that here :o)

W: You may want to run apt-get update to correct these problems

As root, using the key that it says is not available, do this:

# gpg --keyserver wwwkeys.eu.pgp.net --recv-keys FB1A399A71409CDF
gpg: requesting key 71409CDF from hkp server wwwkeys.eu.pgp.net

Cleaning up...

You probably don't want to leave the key in your public keyring ( /root/.gnupg/pubring.gpg )
You can remove it like this:

Delete this key from the keyring? (y/N) y

Also see this post.

If you want to be lazy you can use this as a shell script and call it with the ID of the key you want to import:

#!/bin/bash

if [ "$1" = "" ]
then
cat <<EOT >&1
Usage: $0 PUBKEY_ID_TO_IMPORT
  Run apt-get update and copy the key ID from the error line like:
W: GPG error: http://www.debian.org etch Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0123456789ABCDEF
e.g.:
  $0 0123456789ABCDEF

gpg --keyserver wwwkeys.eu.pgp.net --recv-keys $1
gpg --list-keys $1
gpg --export $1 > $1.gpg
apt-key add ./$1.gpg 
apt-key list
gpg --delete-key $1

If you'd like to be able to run a command like:

$ inline "TEXT TO REPLACE" "REPLACE WITH" filename

Make a shell script with this:

#!/bin/sh

MATCH_STRING=$1
REPLACE_WITH=$2
EDIT_FILE=$3

perl -pi.$$ -e "s{${MATCH_STRING}}{${REPLACE_WITH}}g" ${EDIT_FILE}

It will rename the files to the original filename with the current process ID on the back, and leave an edited copy in the new file.

Alternatively instead of the process ID, a timestamp (of the time now) might be more useful.

You could use:

DATE=$(date +'%Y%m%d%H%M%S')

perl -pi.${DATE} -e "s{${MATCH_STRING}}{${REPLACE_WITH}}g" ${EDIT_FILE}

or perhaps more usefully, for a timestamp based on the last modified time of the file before editing:

TIMESTAMP=$(date '+%Y%m%d%H%M%S' -r ${EDIT_FILE})

Like: 20061005151552

You might want the unix timestamp of the last modified time of the file:

TIMESTAMP=$(date +%s -r ${EDIT_FILE})

or

TIMESTAMP=$(stat -c %Y ${EDIT_FILE})

Both give: 1160057752

then:

perl -pi.${TIMESTAMP} -e "s{${MATCH_STRING}}{${REPLACE_WITH}}g" ${EDIT_FILE}

Sorry if this is a bit random... I'm tired! I'll try and fix it later.

From home before I left:

ssh -R 1234:localhost:22 mywebserver.net

and left something running that kept the session active (and therefore alive)

vi /etc/apt/sources.list

The answer is to plant more trees.... (whoops, sorry Billy!)
Try "which vi" and if you're on Red Hat chances are you'll see:

user@host:~: which vi
/bin/vi
user@host:~: which vim     
/usr/bin/vim
user@host:~: ll $(which vi) $(which vim)
-rwxr-xr-x    1 root     root       473964 Feb  7  2005 /bin/vi

do

alias vi='/usr/bin/vim'

And all your L337N355 will come flooding back to you!

perl -MSocket -e 'print inet_ntoa((gethostbyname '$HOSTNAME')[4]), $/;'

$ lwp-request -o text http://www.aotea.org/john/

This will probably need a few CPAN modules added to work, but the layout is nice and clean - it doesn't line up table cells.

DON'T DO IT!

the /etc/hosts file in the Slackware installer image still has this in it:

# hosts     This file describes a number of hostname-to-address
#       mappings for the TCP/IP subsystem.  It is mostly
#       used at boot time, when no name servers are running.
#       On small systems, this file can be used instead of a
#       "named" name server.  Just add the names, addresses
#       and any aliases to this file...
#
# By the way, Arnt Gulbrandsen <agulbra@nvg.unit.no> says that 127.0.0.1
# should NEVER be named with the name of the machine.  It causes problems
# for some (stupid) programs, irc and reputedly talk. :^)
#

# For loopbacking.
127.0.0.1   localhost
# This next entry is technically wrong, but good enough to get TCP/IP apps
# to quit complaining that they can't verify the hostname on a loopback-only
# Linux box.
127.0.0.1   slackware.example.net slackware

# End of hosts.

Brain-dead Red Hat does this when you install

127.0.0.1     hostname localhost.localdomain localhost

Eeagh! WRONG!

Either or both of these:

PrimoPDF

CutePDF

I have found that the printer driver you chose makes a massive difference to the finished product, some are OK, and some are really crap.

The best driver I have found so far on XP is the latest built-in HP Postscript driver, (HP color LaserJet 9500 PostScript driver) which you can download from here

It's 11MB though, and you can get a 3.1MB one from here

I tried the ones from here or here but they don't want to let you print to the virtual local ports - either LP1 or COM1 or network printers - nothing else - I don't know how to seperate the renderer from the printing interface. :o(

The others I tried were not as good, particularly the "QMS ColorScript 1000 Level 1" which I found suggested here was truly pants!

The "Apple Color LaserWriter 12/600" which was recommended in the CutePDF FAQ was OK, but not great, the main body text of the first page I wanted to print came out in a rusty brown, not in black.

If you are making your PDFs from Word documents and want a PDF which has clickable links (like the index and web links) I'd recommend installing Open Office and exporting to PDF from OOWriter.

Dia rocks...
(I've tried WinFIG and it sucks)

GIMP for Windows & GTK+

If you have to use Cygwin, this ROCKS :o)

http://gecko.gc.maricopa.edu/~medgar/puttycyg/

These two scripts give you a directory history in bash:

cdhist.bash

acd_func.sh

As far as I remember reading, Tahoma font is not allowed to be distributed by itself so that you could use it in Linux like you can with some other Windows True Type fonts...

As far as I know if you already have Windows installed on your machine with Tahoma font in it (it's *CORE* in Windows XP) there's nothing against using the existing copy...

At the top:


use constant DEBUG => $ENV{DEBUG};


or just:


use constant DEBUG => 1;


Then later:


printDebug("some message") if DEBUG;


or


DEBUG and printDebug("some message");


It's good if you want to hard wire the debug level by editing the script, but unfortunately this falls down when you want to use a variable to set it... say a command line flag... in this case, this will work:

use Getopt::Std;

getopts('v', \my %opts);

sub VERBOSE() { $opts{v} }

print "Message...\n" if VERBOSE;

Explanation and benchmark tests are in stefp's thread.

Two nasties I've had to deal with in the last few months, both of which installed registry hooks into the Windows startup and Explorer launch so that they required Windows to load dlls which then locked them as system files, and they would sit there watching the registry to make sure that they re-added any registry entry you deleted, so you couldn't turn them off or remove them.

The only way to get around them in the end was to boot off an XP install CD or some other boot image that can write to NTFS file systems and remove the offending files from C:\Windows\System32 - generally the newest files in that directory.
(From time to time there are a number of files of exactly the same size and different time stamps = the spyware making clones of itself)

The two I've removed (off two different machines) were WinFixer and SysProtect.
Nasty little buggers.

Must-have toolbox for dealing with nasties:

AdAware Anti-Spyware
SpyBot S&D Anti-Spyware
ewido anti-spyware Anti-Spyware
AVG Free Free Anti-Virus
Sysinternals Process Explorer Kill bad processes.
Sysinternals Autoruns Clean out start-up entries for bad processes.
RegSeeker Clean your registry afterwards.

If you need a boot CD:

Trinity Rescue Kit (85MB)

Paragon NTFS for Linux NTFS for Linux trial version (includes a self-burning .exe - only 26.3MB to download)

NTFS driver for DOS (could work from boot floppy if you have a floppy drive. (Haven't tested this)

If you want to read a CDROM Volume ID under Linux (as set by 'mkisofs -V volID') (which Solaris & Windows can read, and Windows displays as the disk label) you can do:


# dd if=/dev/cdrom bs=1 skip=32808 count=32


Or do:


# dd if=/dev/cdrom bs=8 skip=4101 count=4


I got the up-to-date Skype package working, so I don't need to use the "Static binary tar.bz2 with Qt 3.2 compiled in" one...

I downloaded the latest version (currently skype_1.2.0.18-1_i386.deb) from here: http://www.skype.com/products/skype/linux/

If you try and install this you get:


# dpkg -i skype_1.2.0.18-1_i386.deb
dpkg - warning: downgrading skype from 1.2.0.18-2jgh to 1.2.0.18-1.
(Reading database ... 52930 files and directories currently installed.)
Preparing to replace skype 1.2.0.18-2jgh (using skype_1.2.0.18-1_i386.deb) ...
Unpacking replacement skype ...
dpkg: dependency problems prevent configuration of skype:
skype depends on libqt3c102-mt (>= 3:3.3.3.2); however:
Package libqt3c102-mt is not installed.
dpkg: error processing skype (--install):
dependency problems - leaving unconfigured
Errors were encountered while processing:
skype


Which you can get around by doing:

dpkg --force-depends -i skype_1.2.0.18-1_i386.deb

but that's not nice.

This can be fixed by correcting the DEBIAN/control in the .deb file.
One way to do this is: download the .deb package, move it into a new directory
& cd into that directory, then do this:


mkdir skype
dpkg-deb --extract skype_1.2.0.18-1_i386.deb skype
dpkg-deb --control skype_1.2.0.18-1_i386.deb skype/DEBIAN


Now use your favorite editor to edit the Depends line:


vi skype/DEBIAN/control


I changed:

Version: 1.2.0.18-1

to:

Version: 1.2.0.18-2sg


and more importantly changed:

Depends: ... libqt3c102-mt ...

to:

Depends: ... libqt3-mt ...


I also added a menu entry like this:


cd skype
vi usr/share/menu/skype

add this to the file:

?package(skype):needs="X11" section="Apps/Net" title="Skype" command="/usr/bin/skype" icon="/usr/share/icons/skype.png"


Then you need to rebuild the DEBIAN/md5sums file so it knows about the menu file:
# find etc usr -type f -exec md5sum {} \; > DEBIAN/md5sums.new
# diff DEBIAN/md5sums DEBIAN/md5sums.new
36a37
> 6033460bf835d754b25451943db3e92f usr/share/menu/skype
# mv DEBIAN/md5sums.new DEBIAN/md5sums


Then cd back up a directory and rebuild the package:


cd ..
dpkg --build skype
mv skype.deb skype_1.2.0.18-2sg_i386.deb


That's it. Now you can install it:


dpkg -i skype_1.2.0.18-2sg_i386.deb


I found the basic of these instructions here: http://forum.skype.com/viewtopic.php?t=44138 and added a bit to it...

Ages ago I recall finding that the ALSA drivers didn't work on the Tosh, so I was running OSS, but then when I upgraded to 2.6.15-1-686 they stopped... whether that was just because I didn't know to run alsaconf I don't know - but it *did* work fine on the Vaio.

debian-faq-wiki::UseSoundCard
had everything I needed to get ALSA going this time.

ALSA vs OSS

ALSA rocks! - now my Gaim has sound too I can hear when people login or out or send me messages... and my console beeps work :o)

Best of all... I can now use that *gorgeous* AlsaPlayer again... which lets you speed up and slow down and even reverse tracks!!! - crazy :o) great thing to have access to if you're getting bored with listening to your music collection!

It seems there are quite a few dependencies to get this working, and the gaim package doesn't actually recommend the bits you need, so I had a look at the Vaio and a few looks with apt-cache search and ended up getting it working...

I *think* this is pretty much what you need:


gaim (shock, horror!)

All sorted :o)

If you want to process the output of find and some files have spaces in their names, you don't need to use double quotes...

find has the -print0 switch and xargs has the -0 (or --null) switch.


find . -type f -print0 | xargs -0 ls -l

And this year (2006) while the link on the secure-testing page is still out of date, you can fix it with this:


gpg --keyserver subkeys.pgp.net --recv-keys 084750FC01A6D388A643D869010908312D230C5F
gpg --export 084750FC01A6D388A643D869010908312D230C5F | sudo apt-key add -


(thanks to #debian irc channel on freenode.net)

NB1: This will only work this year (2006) - because next year's key signiture will be different.

NB2: This has the side effect of adding the public key to root's keyring which you can see with:


gpg --list-keys


which gives:

You may want to remove it from there once you've imported it into apt, you can do this with:


gpg --delete-key 2D230C5F


Crazy...

I've always had access to Perl (well since I started using Linux in 1994) and yet I've laboured over writing things in C sometimes... like maths stuff! - fancy spending days writing and months tweaking a command line calculator program in C... now I have this *massive* perl script:


#!/usr/bin/perl -w
die "Usage: $0 MATHS\n" unless(@ARGV);for(@ARGV){s/x/*/g};
print eval(join('',@ARGV)),$/;


To convert a decimal number to binary in perl you could do:


unpack("B32", pack("N", $number));


and then chopping off the leading zeros... as per http://www.unix.org.ua/orelly/perl/cookbook/ch02_05.htm

... but TIMTOWTDI, you're better to use:


sprint("%08b", $number);

The one I wanted to know was to delete a cell (or a column or row)... because <Delete> just clears the cell contents...

The keyboard shortcut is <Ctrl--> (Control+Minus) (Hyphen)

http://www.ozgrid.com/Excel/ExcelKeyBoardShortcutKeys.htm

If you want to remove ^M (<Ctrl-M> or Carriage Return) in vim (or vi) you can just do:


s/^M//g


To get the ^M use ^V^M

If you do


s/<TEXT>/^M/g


the <TEXT> is replaced with a newline character (i.e. ^J or \n) instead :o(

If you want to replace text with an actual ^M do:


s/<TEXT>/\^M/g


Of course if you're on Windows using gvim the ^V^M doesn't work, it's just the same as pressing - on Windows you need to use CTRL-Q instead of CTRL-V to escape the special character on the ex command line or to do a blockwise visual selection

From the documentation:

(usr_24.txt)

Note:
On MS-Windows CTRL-V is used to paste text. Use CTRL-Q instead of
CTRL-V. On Unix, on the other hand, CTRL-Q does not work on some
terminals, because it has a special meaning.

(gui_w32.txt)
*CTRL-V-alternative* *CTRL-Q*
Since CTRL-V is used to paste, you can't use it to start a blockwise Visual
selection. You can use CTRL-Q instead. You can also use CTRL-Q in Insert
mode and Command-line mode to get the old meaning of CTRL-V. But CTRL-Q
doesn't work for terminals when it's used for control flow.


perl -e 'for(1..12){my $dir=sprintf("%02i ",$_);mkdir"2005/$dir"}'

(works in standard vi too)

Yeah! - Just what I needed... the tool that's under Gimp...

I used to use Windows paintbrush, but more often than not I needed to save it to xpm and take it back to Linux and tweak it... now I can save it as xpm native :o) perfect... it's the tool for pixel tweaking.

Does logic do your head in?


if(!condition1 | !condition2) equals if(!(condition1 & condition2))

And

if(!condition1 & !condition2) equals if(!(condition1 | condition2))

local $/;
$_ = <DATA>;

$_ =~ s/<table>\n<tr>/<!-- TABLE START -->/i;

And also added:

you can ignore leading spaces with:

Debian Administration :: Mounting remote filesystems using SSH: "module-assistant install shfs"

Truely beautiful :o) and sooo easy!

If you are using the CPAN module within Perl, you can update all of the installed modules on your system using the command:


perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'


This forces CPAN to produce a list of all of the outdated modules on the machine and install them in one hit...

Not recommended for your average joe. you'll have to go over all of your module dependecies and check to see if updates break any of your live code.. still though there are instances where this can be useful.

Something else to think about... have a look here:

On a box where Perl has been upgraded a few times there will be lots of old dirs with modules in...

If you don't have patch installed on a machine it's OK...

You can still use diff to update files...

To update a file using diff & ed:


# (diff -e file1 file2 ; echo -e "w\nq" ) > diffs
# ed file1 < diffs


Bear in mind that it has no context, so it doesn't know where it is in a changed file, it just goes by absolute line number (which means you have to update the bottom of the file before you can update the start - if you're only taking across some of the changes then you need to start at the bottom of the file and work your way back, only updating a chunk at a time... also it's not reversable... patch can see if you're trying to run a patch in reverse... if you try running ed to apply a patch, but accidentally run it against the updated file... then you will really mess it up!

so... make a backup (easy for me to say!) and be CAREFUL!

You have a web directory with 100000 files in it on a DVD.

You want to get a copy of all of the .htm files for editing...

find webdir/ -name "*.htm" | cpio -vdump /target/directory

(-a resets access times on source files, but no point using that on a DVD!)

The letters vdump can go in any order... more logically "padmuv", but "vdump" will be nice to remember! :o)

When you get Error 17 from grub it means it cannot find the partition you want it to boot...


GRUB Loading stage 1.5

GRUB loading, please wait....
Error 17


(ToDo: go back and check this, I got this message off the web, but it looks right)

The tip is...
be careful if you go using:


hide (hd0,0)


Because when you hide partitions it changes their partition type, and if you hide the one with the grub install in it (e.g. where your /boot is) then grub won't be able to access the menu.lst to know what to boot!

(or "how to flash the BIOS on your Debian box without a floppy drive, or CD-ROM drive or Windows partition or USB boot or anything like that...")

This can be done!!! :o)

I have a PC with no floppy & no CD-ROM, it is running Sarge and has a second (empty) hard disk.

I needed to boot in DOS so I could flash the BIOS.

Add this to grub's config ( /boot/grub/menu.lst - I instinctively type vi etc because it's a config file, then realise it's in /boot/grub because it's for booting and needs to be in the boot partition (if that's partitioned)) :

title FreeDOS Image
root (hd1,0)
kernel /memdisk
initrd (hd1,0)/fdos1440.img

Download: Memdisk:

http://syslinux.zytor.com/memdisk.php


I got the newest one out of the SysLinux 3.07 download

http://www.kernel.org/pub/linux/utils/boot/syslinux/syslinux-3.07.tar.gz


although if you apt-get install syslinux you get one too ( /usr/lib/syslinux/memdisk ) which you could use, but that's currently 2.11-0.1 or so.

DOS floppy image:

http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/beta9sr1/fdos1440.img

In Linux use fdisk (or cfdisk as I did) to create a small partition at the start of the empty disk (I did 8MB)


Device Boot Start End Blocks Id System
/dev/hdc1 * 1 1 8001 b W95 FAT32


Use dosfstools mkfs.vfat to format the new partition:

apt-get install dosfstools
mkfs.vfat /dev/hdc1

mount it:

mkdir /mnt/hdc1
mount /dev/hdc1 /mnt/hdc1

copy memdisk and fdos1440.img and the flash program which you download from your hardware vendor into it:

boot, choose FreeDOS Image, Choose 1:

1->FreeDOS (speedup, 386+)

Then choose 1:

1) FreeDOS Beta9 ServiceRelease1 [2004-November-30]

Then choose 2:

2. FreeDOS Safe Mode (skip driver loading)

...and you should now find yourself at a nice little A:\>_ prompt :o)

c:
dir

then there you are :o) You can now flash your BIOS because you are in native DOS.

I'm wondering if you can use a loopback file within Linux as the root filesystem too, so you don't need a disk partition, now THAT would be scarey!!! :o)

This guy needed a CD-ROM:

To power off on shutdown in Linux you need to do two things...

Firstly the kernel needs to know to do it, and secondly the apm module needs to be loaded.

You load the module by adding the line:

apm

to /etc/modules

(or by doing "modprobe apm" for a one-off)

I'm used to doing it with LILO, but with grub telling the kernel to use it is a matter of addding "apm=on" to the end of the "kernel" line in /boot/grub/menu.lst, after all the other stuff.

After all these years of staying away from grub (for various reasons ... mainly because the one time I'd been confronted with it there was a box which wouldn't boot in a computer room, there wasn't time to research, I didn't know anything about it, I didn't like the name, and I didn't know where to start...) I tried upgrading a box after installing a new Sarge box which installs grub by default so I hade something to compare with as a working example...

Installing it was as simple as doing:

As simple as running:


grub-install /dev/hda


(mine was: grub-install --no-floppy /dev/hda )

(You can also use (hd0) instead of /dev/hda I believe.)

Then making /boot/grub/menu.lst

I have:

default 0

timeout 3
