Problem running ssh from remote server

So I have a script which performs some basic commands on another server via ssh. It works great, no issues at all. Let's call this "Script A"

BUT, this working script is to be executed remotely from a different UNIX script on another server, also by ssh. Let's call this "Script B".

When Script B calls Script A, the ssh in Script A no longer connects. There's no error output so I don't know exactly what is happening.

My first thought is that this is keyfile-related. The box with Script A has a keyfile to automatically login to the destination machine. Does the box with Script B also need a keyfile to this destination machine?

So if Script A has this:

Code:

ssh -l $sshid $sship "echo test"

And I call Script A from Script B, nothing is displayed. The values of the connection variables have been tested and confirmed, and whoami shows the correct user. So I can't see how Script A should act any differently when called locally by me, and remotely by another box.

Any help appreciated.

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.
