Screen for linux how did I not know about this

thanks to my friend Gabriella Davis for the heads up on this awesome linux tool

I was having issues with the Sametime TURN server timing out due to my linux session dying or timing out and Gab suggested to look up the screen command.

It is a simple yet affective tool which is implemented usually by default on a linux server that allows you to reconnect to a screen initiated session

you simply enter the command screen from your linux servers command line – the remote session may look like nothing has happened but you are now connected via screen.

carry on as you would normally – if you are disconnected or timed out – log back on the remote linux machine and enter the command screen -ls

[root@myserver bin]# screen -ls
There is a screen on:
        25755.pts-0.myserver       (Detached)
1 Socket in /var/run/screen/S-root.


to reconnect the session enter the command

screen -r session info

for example

screen -r 25755.pts-0.myserver

and you are reconnected

if you want to exit the screen session type exit and you will see [screen is terminating]

Excellent little tool .. thanks again Gabriella for the heads up on this 🙂




Issues with the IBM Install manager GUI on RHEL 6.x ?

If you are attempting to install Connections 4.5 on RHEL 6.3 or above you will have noticed that there is an issue with using the GUI for the IBM Installation Manager with Red Hat Enterprise Linux.

The IM won’t fire up a GUI even though xterm works for other GUI’s on the machine, no errors, no splash screen, no nothing !!

It has been driving both Stuart and I bonkers .. after a lot of digging here is what you need to get it to work :

yum install gtk2.i686 gtk2-engines.i686 PackageKit-gtk-module.i686 PackageKit-gtk-module.x86_64 libcanberra-gtk2.x86_64 libcanberra-gtk2.i686

I ran this and hey presto a splash screen …

So to save your pain .. install the gtk2 packages above 🙂

Also in other news the new installation manager seems to now be fixed so you don’t get the issue with the launch pad complaining there is no Firefox – you may have noticed that there was an issue using older versions of the launch pad with Firefox 10+

Happy installing
