There are other ways you can get into a headless server or a server that is remote to your location. SSH for example. > I will resubscribe and get back into a better habit - I had been > checking every day a year ago, and then life got busy. If you subscribe to this mailing list and read the messages, you will learn a lot. I have. As someone pointed out, there was an issue with glibc. From the CentOS 5.3 Release Notes: <http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.3> 4. Known Issues * When updating from 5.2 to 5.3 you can run into a problem with rpm: "rpmdb: unable to lock mutex: Invalid argument". To avoid this please update glibc before updating the rest of the installation: yum clean all && yum update glibc\* && yum update After you solve the issue(s) you have with the server at this moment, I suggest that you do some reading on the CentOS Wiki, about how to begin securing your server. <http://wiki.centos.org/>
