We're pretty new to LINUX, and are trying to set up a firewall between
our RS6000 and the internet. The RS6000 has both ethernet (the internet
side) and token ring (our entire network is token ring). After never
getting the 2 cards in the AIX box to see each other without logging in
(no Netscape), and the fact that you can't get a better firewall than
that, we decided to give LINUX a try. We put up kernel 1.3.18, and
compiled it with token ring, ip forwarding on and no firewall (for now),
also the SMC Ultra driver is included. Our LINUX machine, of course, has
a token ring card (IBM older 8 bit 16/4) and the SMC Ultra. The ifconfigs
and routes for the two boards as follows:
ifconfig eth0 205.232.52.24 broadcast 205.232.52.63 netmask 255.255.255.192
ifconfig tr0 205.232.52.193 broadcast 205.232.52.255 netmask 255.255.255.192
route add -net 205.232.52.0 netmask 255.255.255.192
route add -net 205.232.52.192 netmask 255.255.255.192
route add default gw 205.232.52.1 # this is our router to the internet
Now the problem. I haven't even been able to start setting up socks yet,
because I can't get my token ring to behave reliably. I can ping from
the token ring to other token ring devices fine. If I ping the token
ring from another device, I lose over half the packets. If I try to telnet
through the token ring, the system hangs with:
kernel panic: skput:over: 00a98214:4
Is there something I'm doing wrong? Have I set up the routes correctly
for my subnet? Do I need to subnet to separate the networks? Thanks for
your patience and help,
Tom
