Not much information on what was done except that it said he hacked into their
system.

I would expect that the programs were originally from UNIX. But you must
remember that they probably have not been updated since OS/2 was first released
almost twenty years ago.

I doubt that this would be considered hacking into their system.

Normally one would expect the reverse DNS to resolve to something since this is
a real web site.

> [G:\]host polarbar.net
> polarbar.net = 66.6.73.189
> [G:\]host 66.6.73.189
> 66.6.73.189 = 66-6-73-189.cttel.net

Probably hosted on someone's DSL connection.

It is normal for the forward and reverse to not match for domains hosted at
home or by hosting companies on shared or virtual systems.

> [G:\]host polarbar.org
> polarbar.org = 64.210.149.200
> [G:\]host 64.210.149.200

I won't touch that question.
