All of a sudden I can no longer ssh into my server running CentOS 4.5 This is what happens: [john at lt-131-jdl-f7 ~]$ ssh -Y -p 2222 192.168.0.1 john at 192.168.0.1's password: Connection to 192.168.0.1 closed by remote host. Connection to 192.168.0.1 closed. And yes, the account does exist and the password is correct! Looking at the logs, I see this: Jun 7 18:51:37 moray1 sshd(pam_unix)[11348]: authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser= rhost=192.168.0.209 user=john Jun 7 18:51:46 moray1 sshd[11348]: Accepted password for john from ::ffff:192.168.0.209 port 57755 ssh2 Jun 7 18:51:46 moray1 sshd(pam_unix)[11352]: session opened for user john by (uid=500) Jun 7 18:51:46 moray1 pam_loginuid[11352]: set_loginuid failed opening loginuid Jun 7 18:51:46 moray1 pam_loginuid[11352]: set_loginuid failed Does any of this make sense? I've tried it on three different clients and get the same thing every time.
