[NTLUG:Discuss] Slow when Connected to Net

[Jack Snodgrass]

A '30 second' delay is usually related to a DNS issue. A DNS Timeout is
30 seconds. 

the /etc/resolv.conf file lists the DNS servers that you will access. 
It will go to one of them ( the first one most likely ) send a DNS
Request, wait ( up to 30 seconds ) and then go to the next DNS Server 
if it didn't get an answer. This may be what is happening with your
box... but maybe not.... 

if you run these commands 

host www.ntlug.org
it should come back fairly quickly with a answer. 
you can specify the dns server to run the query using 
host www.ntlug.org ip.address.of.dns.server.listed.in.recolv.conf.file
that should also return with an answer fairly quickly. 

if there is a 30 decond delay during any of those tests... or a 
'server can not be reached' message.. then you have a DNS issue. 


If you can report back with those results, someone can come up with
some more things for you to do to debug this.
