I set "ForwardAgent yes" in /etc/ssh/ssh_config but that didn't help.. from this verbose output it looks like the line saying "Agent admitted failure to authenticate using the key" is the root of the problem.. Warning: identity keysize mismatch: actual 1023, announced 1024 debug: Trying RSA authentication via agent with 'archie@bubba.whistle.com' debug: Received RSA challenge from server. Agent admitted failure to authenticate using the key. Authentication agent failed to decrypt challenge. debug: Sending response to RSA challenge. debug: Remote: Wrong response to RSA authentication challenge. debug: RSA authentication using agent refused. Maybe there's a problem with ssh-agent? FYI- here's what I'm doing 1. On machine A (3.4-REL): "ssh-agent tcsh" 2. On machine A (3.4-REL): "ssh-add" then enter passcode 3. On machine A (3.4-REL): "ssh <machine B>" 4. On machine B (5.0-current): enter password on machine B 5. On machine B (5.0-current): "ssh archie@freefall.freebsd.org" If I leave out steps #3 and #4 then it works fine as before. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
