We are running OpenSSH versions 4.3 and 5.5 on a mixture of CentOS 5, Debian and Fedora 14 systems. Can OpenSSH log which public key, as listed in the authorized keys file, was used to log in? If so, how? This would be useful for auditing purposes. I don't see a config option, so I'm currently using a custom command via COMMAND="....." ssh-dss AAAAB3Nza..... key1 COMMAND="....." ssh-dss AAAABFFFF..... key2 to log the key. It would be nice if there was a better way. Suggestions? Anthony.
