I have four RH 7.3 servers which had not been updated for a loooong time. I just found out about fedoralegacy.org, downloaded yum and did a "yum update" (excluding kernel) on all four systems. Everything seems fine, except.... when I log in between servers with ssh (any combination) I get two lines in the log similar to the following, whereas I used to only get the second one: Oct 19 18:10:08 archive3 sshd(pam_unix)[23780]: authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser= rhost=h-68-167-xx-xxx.cmbrmaor.covad.net user=root Oct 19 18:10:11 archive3 sshd(pam_unix)[23780]: session opened for user root by (uid=0) I didn't make any config changes, in fact I've NEVER configured ssh, just using what was installed. I'm also getting a login delay following the first authentication failure. There is no failure message in the login panel, only in the log. I only log in once. /etc/ssh/ssh_known_hosts does not exist on any servers, and I didn't get the warning message I remember from first contact with a server (long ago, or after ISP changes). Any suggestions? Dick
