Re: aklug Digest V5 #91

Hi:

Is anyone having problems with running their
webserver. I run a web server that is headless and
suddenly I am not able to access it anymore. My IP
address also changed (it was never static) so I
thought I ask. I think GCI did something to their
network to disable http access.
