Look in /etc/ssh/ssh_known_hosts (if you've created it) and ~/.ssh/known_hosts. Just delete any lines referring to the host to which you are trying to connect.
I ran into this issue when upgrading some Irix machines loaded with their freeware OpenSSH packages to an OS rev that bundled SSH. The upgraded machines generated new host keys which had to be removed manually because of the message you copied below. -Steve -----Original Message----- From: jeff allen [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2003 1:56 PM To: [EMAIL PROTECTED] Subject: known_hosts file I have just recently updated the disk image on all 22 linux machines in our office. If I try to ssh into these machines I get the following error: @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 48:d8:23:48:f1:f5:d4:41:df:70:d8:34:0a:8b:96:e9. Please contact your system administrator. Add correct host key in /.ssh/known_hosts to get rid of this message. Offending key in /.ssh/known_hosts:20 RSA host key for frost has changed and you have requested strict checking. Host key verification failed. How does one go about updating the host key? _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
