ssh/scp is almost an exact replacment for rsh and rcp. My last job I replaced a cluster #$*# of poorly written scripts that relied on rsh/rcp to support over 100 remote hospital clinical systems. In many cases I used sed to quicky migrate to ssh.
If you really have a lot of scripts to modify, think about symbolically linking rcp -> scp and rsh -> ssh.
Also, educate your DBA's on proper script writing and use common practices such as the following:
#!/bin/bash
CMD="ssh -l myuser"
uptime=`$CMD $host uptime`
exit 0;
This way all you ever have to change is one line of each script.
It merely sounds like your DBA's are thinking of excuses to keep the existing use of R commands. I have seen this nearly every company I have worked.
Also note that once you force them to use ssh, they will soon want ssh public keys w/o passphrases so that they can operate w/o using password. Avoid this as well.
