I have a cluster system and I'm seeing a strange problem that I can't figure out.

I have a password-less SSH system setup as I'm sure most cluster system have and I use commands like "scp /tmp/test.txt node1:/temp/test2.txt" in my scripts. The problem that I'm having is that sometimes in those file transfers, some of the characters get changed to symbols like ' @ ^ ə± to name a few and I can't figure out why. When I run large batch jobs from these files on any node it just kills my script and I have to go through and search hundreds of text files to find out what character has been changed so that I can change it back.

Could this be a hardware problem? It's driving me crazy. All my nodes are Redhat 9.

I'm no professional, but it sounds to me like you're in ASCII mode rather than Binary mode... I've noticed similar problems transferring files using command-line ftp... I changed over to Binary and everything worked fine...
