We are having a devil of a time with Ugrads breaking the security on our VMS 4 cluster of 3 782's. Can anyone out there suggest what to do ? The system logs have been checked and do not appear abnormal. The hackers appear to have a fairly high security clearance as they can mod the login files and directories of any of the users in a given sub-tree. How do we spot when this is happening. We believe we have tried the obvious. I am not on this net, and send this message as a service for a co-ordinator who is going white overnight ! Private return mail would be appreciated. I relalise that there are some problems with explaining specific security bugs over a line - how do U know who I am ? But a paper mail address or phone number would be VERY much appreciated Jon
