I must be doing something really screwy - I did as you recommended, then I double-checked my spelling, but no joy. Just as a lark I ran: #dhclient ...then checked /var/log/messages. I found: [DATE] obtunded dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval [NUMBER] [DATE] obtunded dhclient: No DHCPOFFERS received. [DATE] obtunded dhclient: No working leases in persistent database - sleeping. Is this significant? The thing I don't get is that I just put (what I thought was) the same software on 2 computers, and the old, crappy box is fine while the brand-new one doesn't work. I really appreciate the help. </body> </html>
