For some reason ping will resolve something at which point you can use the address to get to it. Erm. Well I'm sure there is some totally logical solution. I presume that 192.168.0.1 is your router? Try the following: Run nslookup Type: server 192.168.0.1 Type: www.google.com (and some other addresses you're getting back as 10.0.0.1 from telnet) What does that say? Also - after dig has returned a correct address does it work i.e. did telnet www.demon.net work after a dig had returned the address but without a ping? I'll say again. This seems very odd but there is bound to be something simple I'm missing. Cheers, Dave.

Still stuck in the ditch here! I cannot connect to anything with a browser (Konq, Firefox), and have tried changing proxy settings without success, but since I don't understand proxy servers I was just stabbing in the dark. I will give your suggestions a try tomorrow.

Still in Windows so haven't tried anything yet, but the router settings contain the following for the ADSL port: MAC Address 00:0F:B5:31:91:77 IP Address 88.106.83.222 Gateway IP 212.74.111.234 DHCP PPPOA IP Subnet Mask 255.255.255.255 Domain Name Server 80.225.248.50 80.225.248.58 so is resolv.conf just referring to the router which then has the nameserver information?

I would try putting the nameserver addresses in resolv.conf - this is what I have on this machine. I had never considered declaring my router to be a nameserver because it is not. OTOH, my setup resolves names adequately for my needs. -- Robert Keep the Yule Logs burning ! |
