Open /etc/resolv.conf as root with your favorite editor and you can also have a look in /etc/hosts so everything is the same on all three boxes
/etc/resolv.conf was different - change them all to match what our router has and all is well!
But more questions. We have a router with dsl modem here. I use dhcp for windows clients. I gave each linux machine a static ip so I can do remote admin. Is there a way to get the ip address of nameservers from the router, like what would happen with dhcp, but still have static addresses for the linux machines?
Does no-one have a solution to this nameserver problem? My Linux machines went down again today - apparently my ISP (sympatico/bell) changed name servers and the ip addresses that worked yesterday don't work today!

Hi Frank,
Many routers (like mine) have a DNS cache, so you can point the linux boxes to nameserver 192.168.0.1 (or whatever IP your router has).
I have a DNS entry that I put at the end of every resolv.conf, its 139.130.4.5 which is telstra's (australian telecom) open DNS server, any ISP can use it.. its handy as a fall back, perhaps you should find one similiar in your area..
