[ILUG] networking issues [resolving]

[Dara Ó Maoilmhichíl]

hi all,

i have a linux machine set up for dhcp. No host name, no domain, no
routing or dns etc, i expect everything from dhcp.

So, in office 1, all works fine. Linux dhcp, dns, cache, etc.

In office 2, all also works fine, again linux dhcp, forwarded dns(to
isp), no web cache.

But in office 3, eircom netopia router with dhcp. 

Now the latter is the problem. With windowas running on the laptop,
everything seems fine. However with Linux running, there is a 'lag' of
a few seconds before internet connections are made.

For instance, going to a web page, checking email etc, the first few
seconds seem to be spent looking for the thing (resolving the name).
But once found all the data comes down very fast.

So the resolving seems to be the issue. To asser this i check what
would happen if i enter http://64.233.187.104/ -  i get google
immediately. Entering http://www.google.ie and i have to wiat 5+
seconds.

Crazy! 

Now, I've check for dropped packets and all sorts of config stuff
including the netopia router [whose s/w seems to have magically
upgraded so i had to re-find my way around], but considering the linux
setup works in all other environments i've tried and the windows setup
seems to work in this case without a hitch, I really must wonder is
the netopia linux-unfriendly or what ?

Any pointers greately appreciated.
