running script in cron - with ssh commands - not working
I ran an ssh command to run a script on a remote server
ssh -l <user> <servername> /path/to/script/scriptname
This works fine - and the script is executed correctly.
However - I put this command into a script, that I want to run from cron every hour, to execute the file on the remote server every hour, but the process appears to hang... I can see the process but it is not doing anything. It only takes 3-4 seconds to run from command line but doesnt do anything when cron submits it:
root 16528 16527 0 14:46:00 ? 0:00 /usr/bin/ksh /<pathtoscript>/<script>
root 16527 233 0 14:46:00 ? 0:00 sh -c /<pathtoscript>/<script> > /dev/null
root 16532 16528 0 14:46:00 ? 0:00 ssh -l <user> <server> //<pathtoscript>/<script>
This just hangs.... Any ideas?

SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.
OPTIONS
See ssh(1).
FILES
See ssh(1).
