net connect problem, sleep?
I am running Debian 2.2.17 on my office machine connected to a university
network. When I'm in my office things work well, and I am connected well to
the outside world. When I leave the office and the machine is not being used,
it cannot be pinged from the outside world (it can be pinged when I'm using it
in my office). I thought this might be because the machine is going to sleep
when I'm gone (the screen does go blank), but I couldn't find any power saving
system turned on in the bios (I may not be looking in the right place, or know
what I'm looking for). I am now able to keep the machine accessible from
outside by running a javascript program that reloads a web page every couple
of minutes; this allows me to ping the machine at will. But I'd like to avoid
this, and would like to fix the problem.
I was wondering if it was in the ethernet card or driver. My
startup message reads:
eth0: 3Com 3c900 Cyclone 10Mbps TPC at 0x1080, 00:50:04:0d:87:e1, IRQ 11
8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
MII transceiver found at address 24, status 182d.
Enabling bus-master transmits and whole-frame receives.
I was wondering if replacing that ethernet card with a linksys 10/100
card (and tulip driver) would help; I have it lying on my desk.
Any suggestions would be appreciated,
Ric
