Hi Sunil,

you're having problems with your network connection to CERN. This will block any access to /afs/cern.ch at times. It should not affect the system in general, but having anything below /afs/cern.ch in environment variables like PATH or LD_LIBRARY_PATH will hang pretty much any command, for example.

Regards,
