any way to avoid network to be deactivated after a period of inactivity ?

Hello,

here is something I don't understand. I've this network up and running at
home with a linux red hat 9.0 and a windows 98 pc. The linux is used as a
gateway with an adsl connection and then forward the traffic to the Windows
pc through eth0.
Everything works fine regarding NAT, but after 5-10 min. of inactivity on
the linux box, the eth0 interface goes down, as well as thee local loop
(the ppp connection stays up though). I then have to restart the network
and the iptables rules in order to have the internet connection available
on my windows pc.
Is there anyway to avoid this and make the network interfaces permanently
up and running, as well as the routing table and the iptables rules ?
Am I missing something here ? (sorry, but i'm kinda new to this :-( )
TIA

Vincent

I know this problem. I've found apmd to be the reason. Why the solution
I've found works for me, is not really clear to me. So don't ask me.
But I set in /etc/sysconfig/apmd the following line:
NET_RESTART="no"
After the description provided by the file, a setting to yes this
Variable is to avoid the scenario you describe. But exactly the opposite
happens, it seems to be the reason.
If anyone could explain this behaviour, I'd be interested in reading.

That's interresting. I search the doc in vain for an answer to this problem
but I'll definitly keep on looking. Thanks a lot for the clue anyway :-)

This *sounds* like crontab (man crontab) might be used to remove inactive
networking modules. I've never done this, but from Documentation/kmod.txt
in the kernel source tree,

To periodically unload unused modules, put something like the following
in root's crontab entry:

0-59/5 * * * * /sbin/rmmod -a

It will very likely be an item that's configured via a RH script, but I
don't run RH.
