Hello, My environnement is Debian Etch, and the version of ssh is 4.3p2. I wrote a command <mycommand> that starts a python program. This program calls a blocking method on a gamin monitor that waits for file system changes (new files, for exemple). I had to launch this python program (in mycommand) with "nohup" and "&" at the end of the line because if not, mycommand is blocked. Then when I enter the distant machine by writing only 'ssh <ip>' and after connection, <mycommand> + ENTER, it returns correctly (I can continue to write thing without to have to do crtl+c). But when I launch the command like this : 'ssh <ip> <mycommand>', it doesn't return. It is blocked and I have to do ctrl+c to unblock. Furthermore, the python program is correctly running on the distant machine. Do you have any idea why 'ssh <ip> <mycommand>' is blocked ?
