[clug] strange network behaviour

[Steve Walsh]

Try a nslookup/dig on the Win2k/linux boxes, and that will tell you if you
are getting DNS timeouts, blocks or the like.

If you are getting timeouts, I would think the problem is with your firewall
block rules, but check your resolution first, then look at firewall logs to
see if it's dropping packets.

Hi,

I am unable to access the site www.ibiblio.org from my home network.
Initially I thought that the site was down but soon realised that I
could access the site from my firewall but not from the other computers
on the network (linux or windows 2k) where firefox tells me that the
site cannot not be found. This has never occurred with any other site
that I know of, although it may have happened with "small" sites and I
have interpreted this as the site no longer being online..

I thought that the problem was related to name resolution so I entered
the ip address in the client's browsers and was able to access the home
page. I have the feeling that the dns lookup times out but I do not know
what to do next...

My firewall runs firestarter on Fedora 3 and is very simply setup with
most ports blocked by default.

Any ideas on where to start?

Thanks

Nic
