From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.10-ac4 i686) Description of problem: The scp command does not take a -1 option like the ssh command does to force it to use the ssh1 prototcol. I imagine it probably doesn't take a -2 option to force the use of ssh2 protocol either. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Try to scp to a ssh1 machine without modifying /etc/ssh/ssh_config to hardwire the protocol to version 1. 2. 3. Actual Results: You get the normal unknown switch message. Expected Results: scp should take equivalent options to ssh. Additional info:
scp shouldn't offer every one of ssh's command-line options, and it doesn't need to. Use '-o "protocol 1"' to force scp to use protocol 1. Marking as "won't fix" because I've seen this come up on the developer mailing list before, and this tends to be the answer, and we don't want to change it from the upstream default.
