I was told that some BBS's which you can telnet to via the internet are
able to resolve userids. Perhaps they were using identd. Does identd
only have to be run at this end (where the MUD is running), or is there
more to it? CPU time is not a real problem, but memory is always gobbled
up, so if something was light on the memory requirement, the I would be
interested in tying out using it. There are some instances where you
don't want to ban a site, but banning a specific user would be ideal.
Also being able to write to a system administrator and specify the actual
user who was the culprit of problems is MUCH more effective than just
saying someone called and did this..
This isn't something I harp on, because it is rare to have problems this
bad with users. However I have a very low tolerance for sexual or racial
harrasment, and take extreme action in those types of cases.
