Show seconds in ls -l output on Solaris 10

If you need to show the seconds (and year) in the output of ls -l on Solaris:


$ ls -le /path/to/file

Ardour4, JACK, ALSA... Rosegarden, qsynth etc...

When you install Ardour on a fresh Debian install you will probably find that the sound isn't working.

Here's what I did to get it going.

sudo aptitude install ardour

I also installed these.

sudo aptitude install Qtractor
sudo aptitude install audacity

I installed these 2 to convert mp3s to ogg so I could import them.
Qtractor lets you import mp3 but ardour doesn't

sudo aptitude install ffmpeg
sudo aptitude install dir2ogg


To control/configure jack....

sudo aptitude install jack-tools qjackctl

This lets JACK and Pulse talk to each other, otherwise they lock each other out.

sudo aptitude install pulseaudio-module-jack

I'm not sure if I needed this, but this was one step:

sudo aptitude install linux-image-4.6.0-1-rt-amd64

This was the key: https://ubuntuforums.org/archive/index.php/t-986080.html


I would bet you need to look at the Ardour mixer and route the Main Output channel to your soundcard outs.

In Ardour press Alt+M (to view the mixer) then at the bottom of the Main Output strip there should be a button labeled Output - click that, then add your soundcard outs to the appropriate channels in the dialog box that pops up.

There shouldn't be any issue with the format of your wav file as ardour will resample things for you (at a better quality rate than ProTools actually).

This issue could also stem from you not having JACK configured correctly. In Ardour's open dialog, if you haven't already started the JACK audio server, there will be a tab that says audio setup - this is Ardour's own JACK startup script. It should work fine by default, but you should probably read up on JACK and qJackCtl.

To get Rosegarden going I used this page: http://gauthampai.livejournal.com/62383.html
The key to that was installing the soundfont, and qsynth.

Once you've got it configured and working, you also need to start qsynth before Rosegarden and have it running the whole time Rosegarden is. If you restart qsynth you'll probably need to restart Rosegarden for it to reconnect.

Installing 7-Zip plugin in MobaXterm

I like MobaXterm http://mobaxterm.mobatek.net/

I like 7-Zip http://p7zip.sourceforge.net/
(In my previous version of this How-To I used 7-Zip for Windows from http://www.7-zip.org/ ) to open the downloaded archive, but now you can do it all from within mobaxterm.

To get 7-Zip working in MobaXterm I downloaded the 7-Zip package from a cygwin mirror... (find your closest one at https://cygwin.com/mirrors.html )

You can find the current version with this:

wget -qO- http://mirrors.kernel.org/sourceware/cygwin/x86/release/p7zip/ | sed -e 's/<[^>]*>//g'

Then download the version you want. e.g.:

wget -N http://mirrors.kernel.org/sourceware/cygwin/x86/release/p7zip/p7zip-15.14-2.tar.xz

You should now have this file in your current directory:

-rwxrwx---    1 Administ UsersGrp   1039440 Apr  5 05:12 p7zip-15.14-2.tar.xz

You can unpack the tar.xz with gnu tar:

tar xvf p7zip-15.14-2.tar.xz

You can then create the package using the p7zip from the unpacked tar file:

usr/lib/p7zip/7za.exe a p7zip.mxt3 -tZIP usr

Finally move the file you have created to C:\Program Files (x86)\Mobatek\MobaXterm Personal Edition
You will probably need to do that step from outside MobaXterm otherwise you won't have permission to write to the directory.

Then restart MobaXterm.

job done.

If you don't know where to find your home directory from Windows you can open it in Windows Explorer by doing:

$ open $PWD

from the command line in your home directory.

NB:
If you have trouble with the step creating the mxt3 file you can do it via Windows too:
Originally I opened the directory it created ( p7zip-15.09-1 ) in Windows Explorer and right clicked on the usr directory and chose 7-Zip -> Add to "usr.zip" (NB: Choose usr.zip, not usr.7z here)
This created a .zip file containing the usr directory.

I then renamed usr.zip to p7zip.mxt3

To replace text in vim with line number

e.g.:

mv file_abc.jpg pic.XX.jpg
mv random.jpg   pic.XX.jpg
mv other.jpg    pic.XX.jpg
mv name.jpg     pic.XX.jpg

If you do this:

:%s/XX/\=line(".")/

Make SSH ignore SSH key

Make SSH ignore your SSH key, not prompt for a passphrase, only use password:

$ ssh -o PreferredAuthentications=keyboard-interactive -o PubkeyAuthentication=no destination.host

find things...

Find files that are not world readable and make them readable:

sudo find . -type f \! -perm -4 -exec chmod o+r {} +

Find files that are not group readable

find . -type f \! -perm -40 -ls

Find files that are group writable

find . -type f -perm -20 -ls

Find files that are world writable

find . -type f -perm -2 -ls

To find if a Solaris host is running on an LDom

If the file /usr/sbin/virtinfo exists, run:

$ /usr/sbin/virtinfo -a

If you run it as root it will also tell you the hostname of the Control domain and the Chassis serial#.
