internet strangeness
 
I've got a slackware 10.0 installation and I've had it since 9.0. Just recently, last night in fact, it began to get a bit buggy on the internet. At the same time, my other linux computer, also slackware, began having problems.

They're both on a LAN, made using a dlink router, I'm using addresses 192.168.0.101-105 with the 4th plug in the dlink router going to a netgear router in my room.

This configuration has been working flawlessly for many a month, but just last night I became unable to access websites on firefox. I decided it was probably a problem with my ISP (Adelphia) as it always is and I went to sleep. Today however, I found that the problem is presisting. When I try to ping it will usually take some time before ping will type that first line, something to the effect of
PING yahoo.com (145,357.345.234) 45(84) bytes of data

then afterward it will take quite a while before it starts saying that it got responses even though it will report response time at 58 to 70 ms when it does come in. Each response takes about 4 to 8 seconds.

Now I can't even do that though. Now when I try to ping a website it will usually say that it got responses in ample or slightly more than ample time, but it still takes a few seconds before it says that it got each response in so many miliseconds. When I ping the IP address that it says that it resolved however, it works instantly and just as it should.

So, it seems I've a problem with address resolution, or something ot that effect. Does anyone have any idea what this could be and why it might happen?

Thanks in advance. :)

Apparently I can use firefox and it will work, but I've got to give it about a minute or two to resolve the IP address from the domain name, then the one site it resolved will work fine, but I've got to wait a certian ammount of time for each site.

what is the output of : dig yahoo.com ?
this will also give the dns lookup time.

Oh, sorry, some friends of mine on IRC helped me with this.

Apparently the way my /etc/resolv.conf was set up it was only geting one DNS host from my ISP through the router, and that one was laggy laggy laggy, so I changed my resolv.conf to point to 2.4.4.something which fixed it right up.

Thanks for your quick response egag.
