There is some information in the Cern TWiki.
Register your CERN NICE account for TS access:
on lxplus run
rdesktop -d CERN -k ch-de -g 1024x768 -T "NICE TS" cerntslhcb01.cern.ch
you probably want to adjust the keyboard layout and maybe the screen size
Brunel and STMonitors is used as example here. Start a shell using the LbLogin local icon on the desktop and prepare environment
SetupProject --build-env Brunel
get the source form CVS (getpack should work, but it always got stuck for me so I used CVS directly):
cvs -d :pserver:anonymous@isscvs.cern.ch:/local/reps/lhcb checkout ST/STMonitors
then go to cmt directory of STMonitors, configure and build
SetupProject Brunel cmt config setup.bat cmt make
You might want to prepare SSH access to cvs (if you need to commit): http://cvs.web.cern.ch/cvs/howto.php#accessing-ssh
