using graphical software on Ubuntu as root after you’ve logged in remotely

Sometimes I find myself in the situation of having to lauch some graphical software like synaptic, gedit, baobab while already using the server as root from the command line. I do not want to ‘exit’ my session and use the previous methods of which I’ve written in the past.

This is how I did it.

koolinus@localhost:~$ ssh -Y koolinus@remote.server.it
koolinus@remote:~$ sudo -i
root@remote:~# touch .Xauthority
root@remote:~# xauth merge /home/koolinus/.Xauthority 

And that’s all. Now I can launch the needed program without interrupting my root session, for example:

root@remote:~# baobab &

Ubuntu 13.10 (Saucy Salamander) released

Fwd: Ubuntu 13.10 (Saucy Salamander) released

The Ubuntu team is very pleased to announce the release of Ubuntu 13.10 for Desktop, Server, Cloud, Phone, and Core products.

Codenamed “Saucy Salamander”, 13.10 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs.

Ubuntu 13.10 introduces the first release of Ubuntu for phones and Ubuntu Core for the new 64-bit ARM systems (the “arm64″ architecture, also known
as AArch64 or ARMv8), and improved AppArmor confinement. In addition to these flagship features there are also major updates throughout.

Ubuntu Server 13.10 includes the Havana release of OpenStack, alongside deployment and management tools that save devops teams time when
deploying distributed applications – whether on private clouds, public clouds, x86 or ARM servers, or on developer laptops. Several key server
technologies, from MAAS to Ceph, have been updated to new upstream versions with a variety of new features.

Maintenance updates will be provided for Ubuntu 13.10 for 9 months, through July 2014.

getting packages info on Ubuntu

Recently we’ve decided to move all our CentOS 5 server installations to a more modern, and bioinformatics friendly, environment. So the choose was on Ubuntu, in it’s 12.04 LTS version.

Some commands are different, especially those for exploring packages, their releases and such.

For example to see what packages install $something now I do a:

sudo apt-file search $package

while to see a package’s details, for example nano, I give a:

sudo apt-cache show nano

Description-en: small, friendly text editor inspired by Pico
 GNU nano is an easy-to-use text editor originally designed as a replacement
 for Pico, the ncurses-based editor from the non-free mailer package Pine
 (itself now available under the Apache License as Alpine).
 .
 However, nano also implements many features missing in pico, including:
  - feature toggles;
  - interactive search and replace (with regular expression support);
  - go to line (and column) command;
  - auto-indentation and color syntax-highlighting;
  - filename tab-completion and support for multiple buffers;
  - full internationalization support.

That’s all (for now).
