Cannot connect to internet or printer

[Ken Heard <ken@heard.name>]

I have sarge in a P3 computer.  For months I have been able from it to 
connect to the internet and also to print through a print server using CUPS.

Since boot-up on Sunday morning 18 December I was able to connect to the 
internet and print.  Suddenly, by Sunday evening was unable to do either.

I tested the connections by pingng both the gateway and the print server 
-- successfully.  Dmesg showed that eth0 is up and running.  I was also 
able to connect to the internet and print through the print server from 
two other computers, both Windows.  Other than using Konqueror, the only 
operations I performed just before this breakdown was to install the 
equivs package and remove xprint.

I have concluded that there is a software problem in the P3 computer, 
but do not know what to look for.  I would appreciate any and all 
suggestions.
