Couple quick thoughts:

- Do really want your job to deal with scripting to use scp and passing 
around credentials? I think usually it is better/easier/safer to use 
HTCondor's file transfer mechanism (which is scheduled) to move files 
from your submit machine to the execute machine ... see

- If you need to use scp etc, the most common reason I've encountered 
for an exit status of 255 in scripts that run outside of my home 
environment is because I am contacting a host not in my 
$HOME/.ssh/known_hosts file (almost certainly not the case if you are 
using HTCondor without a shared file system or across administrative 
domains).  To remedy, consider passing command-line switches to scp/ssh 
like so:
   scp -o UserKnownHostsFile=./my_temporary_known_host ssh_host ...

Hope the above helps
