Slackware IP Forwarding

Hi.  I'm running Slackware 2.0 on a 386DX40, installed from the Infomagic Sept 96 CD set.  An application (TNOS) I run says I need to have IP Forwarding enabled in the kernel in order for it to talk to Linux. Since I haven't been able to make it work, I'm wondering if this is the problem.   My question is, how can I tell if IP Forwarding is in the kernel?  Also, how can I determine what kernel I have now?  If I have to upgrade the kernel, it means I need to install compilers and download the source code, which I can do but don't have enough free disk space.
Thanks for your help.

Hi Dexter

your first quedtion adresses ip forwarding. To find out if it is enabled you should also have the /proc filesystem compiled. many precomliled kernels have /proc filesystem enabled so you will find the file /proc/ksyms (it is no real file). If you don't find this file /proc was not enabled and this answer will not help.

So if the file is there you can find out if ip forward is enabled with the following command: cat /proc/ksyms | grep ip_forward

if you get back something like this

08154711 ip_forward

you have ip_forward aktivated.

your linux version is usualy displayed while booting, with the shift pg_up key you can scroll trough the bootmessages.

Precompiled kernels can be found at:
ftp://wcarchive.cdrom.com/pub/linux/slackware/bootdsks.144
ftp://ftp.delix.de/pub/Linux/Kernels
maybe you will find a kernel that meets your requirements

maybe have a look at http://www.linux.org

bye Michael
