Unless something has changed that I don't know about, you cannot su to another user when executing a command via ssh. Something about the su command needing you to be assigned a tty.
What you CAN do is sudo commands. So if you need to run something as root and you have sudo rights your script can do this:
That will ssh to "host" and execute "somecommand" as root.
Also, your script examples are a little flawed. You have ssh on it's own line and then some commands after that. That's now how that works. In your examples, you would ssh to the box in question and once you exited that box the remainder of the commands would be run. You can put your commands into a script on the remote server and then execute that script:
NOTE: I keep putting the command in quotes but that's not required unless it contains spaces.
Even if you do this you're still going to have issues with switching users (I believe. you'll have to try it). If you need all the commands in the remote switch to run as root you can just "sudo /path/to/script".

If servera is down - the scp never times out ... it just hangs eternally..
It is possible to specify a timeout in my script - so if scp fails/hang for more than 60 seconds I assume its failed ?

I'm using scp to copy files to another company via our 4.3.3 server. I am having transfer problems right at the transfer point in scp. Below are 2 debug outputs showing the bottleneck. The lower level debug preceeds the higher level debug output. It just seems to stop and refuses to transfer... (0 Replies)
Thanks to this forum, I was able to get a program running that uses SSH to control programs running on other hosts. Now I'd like to enhance it.
The control program on the target hosts occassionally needs to be updated. Updating the menu program on the source host is easy as it is on one host. ... (1 Reply)

ssh-argv0
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).
