I don't like the timestamps: 21:32:38, 20:33:33, 21:33:42, 20:33:42. Why is that? By the way, most probably the access has been done by my provider. They are denying it, but there is overwhelming evidence: the username used is the one that they gave me, which is the word admin and a string of 7 digits. The username should be known just by me, my business partner and my provider. The username was anyway invalid in the system, because I had disabled SSH access from all users but the ones in a group. Nevertheless, in their records, the provider had another user name that I didn't disable (stupid me) because they did some maintenance work not long ago. I can't see any access from the correct user name since the last time I had authorised them to access the server.
We covered something similar a little while back. Don't know if it's the same problem you're seeing but this might help shed some light... http://lists.centos.org/pipermail/centos/2006-November/072459.html Will. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
