This is quite possibly the clue I needed, I'll have to spelunk a bit more. I have /usr/bin/scp /usr/local/bin/scp they are different executables. on both systems, 'which scp' returns /usr/local/bin/scp while 'su - which scp' returns /usr/bin/scp >From each system, ssh into the other gives a shell where 'which scp' is /usr/local/bin/scp. Why I can scp one way but not the other is the mystery... chkconfig --list | grep ssh shows sshd running on both systems.

Are you sure the destination system is running OpenSSH? http://www.snailbook.com/faq/scp-ossh-to-ssh2.auto.html -- William Hooper -- Shrike-list mailing list Shrike-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/shrike-list ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
