I use the below options with SSH in various scripts. Sometimes i have to adjust the -n or use a -N option.

The -o ConnectTimeout=15 may just be for initial connections and therefore not help you as it sounds like your session is running but timing out somewhere and not exiting.

Code:
# SSH_OPTS :
#       ConnectTimeout=15
#                       Causes ssh to quit if not connected withint 15secs
#       StrictHostKeychecking=no
#                       Causes ssh to NOT ask for yes/no if the remote_server
#                       host key is unknown which causes the script to fail
#       LogLevel=quiet  Surpresses the banner information
#       -n              Prevents reading from stdin. Without this ssh overrides
#                       the current process (i.e the script) with itself.
#                       Used so ssh can run in the background
#       BatchMode=yes   Passphrase/Password querying will be disabled

SSH_OPTS=" -o ConnectTimeout=15 -o BatchMode=yes -o StrictHostKeyChecking=no -o LogLevel=quiet"

Then just call ssh with ssh $SSH_OPTS blahblah.

The -n may help also as running remote ssh calls within a script can just overrun your existing shell in its own process and therefore make it hard to trap output from.

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
