Weird.
There is perhaps some processes spawn by some /etc/profile.d/xxx.sh script.
(or by some PAM module).
To check that:
- connect first interactively to the remote host
- from another terminal start such an ssh that hangs
- from the interative one list the processes involves in the hang
for example with pstree. Look for the most recent processes sons of some
sshd
Try perhaps adding the -n option to ssh to not give stdin to the remote
command, but I think that this will not work.
