Passing SSH Command Parameters
On Solaris 5.9, is there any way to pass parameter(s), via SSH, to a command defined in the remote host's authorized_keys file?
We have a menu that uses SSH to control some apps on our various hosts. I've been tasked with enhancing it and making it more secure.
So far, the local host menu will use SSH to call a .ksh script on the remote host, with one of 4 parameters, to either start, stop, restart or check a program's status. That works fine.
What we would like to do is this:
1. Put the remote .ksh script name in the authorized_keys file, on the remote host, in the front of the key line, for the user calling it, from the local host. That would limit the user, using the menu, to only being able to run this .ksh script.
2. When the user make a choice on the local host menu, pass only the chosen parameter via the SSH login.
When I try it, the remote .ksh script runs, but errors out due to the parameter passing failing.
Is there any way to pass just the parameter(s)?

I'm trying to run a command over ssh to AIX 5.2, something like:
ssh machine ls
but it just hangs. I can ssh into the machine and run a command, but can't pass it like above. Is there a security setting that disables this by default? If so, how do I change it?
Thanks! (8 Replies)

ssh-copy-id
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)
