Title: checkXusers

Authors: Bob Vickers

Abstract:

This script checks for people logged on to this machine from insecure X servers. It is intended for systems administrators to check up on whether users are exposing themselves (and hence the system) to unacceptable risks. Like many commands (e.g. finger(1)), it could potentially be used for less honourable purposes; naturally I disapprove of this.

Title: Dump Lastlog

Authors: Gene Spafford

Abstract:

Under most versions of Unix, there is a "lastlog" file that records the time, and sometimes the terminal, of the last login for each user. This is then printed as part of the next login as information. Some systems also include information on the number of invalid attempts on the account since the last valid login. On my systems, the file /usr/include/lastlog.h describes the format of this file. Note that I have not seen a "standard" utility that prints this information out in human readable form you have to write your own! Well, here is my Perl program to dump the file for SunOS/Solaris systems (it works on both). If your lastlog format is different, then you simply modify this. You may also need to adjust the path to the lastlog file.
