So 10.254.2.254 is router, dgw, dns and it working 10.254.2.1 is machine you are on that can't do dns * Have you check any firewall issues * dig is your friend dpkg -S /usr/bin/dig dnsutils: /usr/bin/dig link http://packages.debian.org/sid/dnsutils with this you can query you dns and test the setup so something like this from the .1 machine (and even test from the .254 machine to test as well) dig @10.254.2.254 google.com this tells dig to talk to 10.254.2.254 and make a request for google.com (this by passes the local resolv library and make a direct request to the dns server) see if that give you any answers - check the difference between doing this on .1 and .254. also try using you ISP's dns server address instead of 10.254.2.254 another tool would be tcpdump, in another windows/screen try this tcpdump -pni <interface> host 10.254.2.254 and port 53 and then run the dig command again, you should see requests being sent to the dns server and you should see replies from there. depending on the results would depend on what to do next :) [snip] In another email you said you can't install any packages because you can't download to that machine. if you download them to another machine and then scp over you can use dpkg -i <packagename> > > > Advice on how to troubleshoot further would be much appreciated, thanks. > > > -M > > ________________________________ > Take your contacts everywhere.
