I originally began this topic on another thread, but I've made so many changes (I started over and got most things working) that I thought it would be better to begin again. The original thread can be seen at:

Ok, So I have a MDK 9.2 box hooked up on a LAN by a switch to a win 98SE box and a winXP box. I have enough working that I can SSH into the linux box, the linux box works as my web server, and the linux box can ping every machine out there (including web) but not itself.

I'm using shorewall and have the info argument turned on for every policy, but am not seeing anything logged in /var/log/messages for these pings. I get a "request timed out" if I try to ping from any other machine.

Strangely, I also have samba mostly set up and the windows machines can see the linux box, but can't connect to it. I set the ignore_all flag in sysctl.conf to 0 and have allowed icmp 8 and icmp echorequest (should be the same, but it's not working either way) to accept. I'm at a loss.

I also can't ping by hostname from the linux box, though that is working from the windows boxes (except for pinging the linux box, whose hostname they can't find).

route -n
ifconfig
BTW, I'm not using eth1 currently. I'm hoping to set up a second subnet later, but for now, I just want to get this one working fully!

Can you post the output from:
grep "" /proc/sys/net/ipv4/icmp_echo_ignore_*

and:
iptables -nL

Ok, I think I see the problem, but now I'm unsure of the solution.

Both of those files are set to 1. They're zero in the sysctl.conf, but I guess I'm not running whichever command will actually refresh those values.

iptables -nL
