I'm in no way an expert with linux.. but from your description the other machines are running through your machine.. which is then running through the firewall.. correct?

are you running a dhcpd on your machine that other machines need?

if so are you running that deamon?

like I said.. am no expert.. just fallen for this mistake myself :)

Hi All,

I'm stumped and looking for something more or less obvious.

My system is RH7.3 with 2.4.20-13.7 kernel and everyting else reasonably
patched up. My system is connected through a firewall to the net (DSL) and several other windows computers get the net through my machine via the
local lan. (I have a static IP address)


Day before yesterday, I rebooted my linux machine. It came up fine, but
the other computers can't access the net (I can. Proof is that I'm sending
this e-mail). I checked ifconfig and saw that both of the network cards
are present. (1 is a 3c59x and the other is a linksys card that I get
working with a tupip driver.) Strange thing is that 'lsmod' does not show
the tulip driver loaded. So I 'insmod' pci-scan.o and tulip.o . They both
load, but still no luck with the local net. I tried bringing the linksys
card down (ifdown eth0) and then back up again (ifup eth0) with the
modules loaded, but it made no difference. I then booted into windows and the local lan works through the linksys card.


What obvious thing am I missing here?

Thanks,

Mark


Check your routing table and possible firewall problems.

Easiest test is to ping this machine with the address of the LinkSys card from another PC on the LAN and check whether the card responds.

Always take things back to the lowest level first. You say the other PC on the LAN can't get onto the net, but you don't mention whether they can even see the troublesome PC in question.

Regards,
Ed.
