I use ssh to run some command remotely,something like this:

ssh user@host 'sudo command'

after that, I got this line shown in the shell:

'unknown': I need something more specific.

what does it mean? I'm sure it's the result of the execution of the command, should be something related to ssh itself.

What command were you trying to run? –  Collin Aug 25 '12 at 4:15
I searched for the msg you get. You should too. maybe you're using "torque"? and maybe it needs a patch? osdir.com/ml/clustering.torque.user/2006-01/msg00193.html –  barlop Aug 25 '12 at 7:22
