It works the same regardless of whether you have Win95 or Linux on the
other boxes.
I've setup my system to do this.
I also installed "diald" so that when any user on any of the LAN clients
tries to access the internet while the connection is down, my linux box
will automatically dial out and establish a ppp-connection and setup the
routing.
I've included the config I'm using.
It's not necessarily perfect, but it works good for me!
If you want a book, Barnes & Noble carries "The Linux Network"
which covers this and Samba and...
(BTW, I'm using RH6.0)
===========
This is my /etc/rc.d/rc.local file (below).
My NE-2000 compatible nic doesn't get detected at boot,
so I added the depmod and modprobe lines here.
I put "alias eth0 ne io=0x240" to in /etc/conf.modules, but that didn't
seem to fix the problem.
The "ipchains" lines configure forwarding and masquerading.
The "ipfwadm" lines are the old commands that worked with RH5.2.
ipfwadm is *supposed* to work with 6.0 too, but I don't believe it does.
I setup the other PCs with 10.x.x.x addresses.
The "/8" means netmask = 255.0.0.0.
Using redhat's netcfg tool, I clicked on "Network Packet Forwarding
(IPv4)"
set the "default gateway" to be the IP address of the linux box
(10.1.1.130)
set the "default gateway device" to be "ppp0".
and put in a static route: if=eth0 addr=10.0.0.0 mask=255.0.0.0
gw=10.1.1.130
Since my system doesn't seem to pickup the ethernet card at boot,
(I think because it's configured to be at I/O=0x0240 and that's not one
of the addresses that ne.c probes),
I think I have to go into netcfg (as root) and click on
interfaces/eth0/activate at boot.
I'm not sure because I almost NEVER reboot my linux box.
I'm also running a DNS server (bind) on the linux box.
If you want the config files for that, let me know and I'll e-mail those
too.

I believe what you need to do is to turn off output buffering in the
programs you are calling (the called program, not the calling program).
I don't remember how you do this in C.
In perl it's something like "$| = 0;".
If I remember right, in C there's some call (fcntl ?) you make after
opening the file to set the buffersize to zero.
Try any basic C book, or a C newsgroup.
Hope this helps.

As with any such thing, a project needs a champion or three fiendishly
devoted to producing results. The guy pulling most of the week decided
to go on a world tour for a long spell. There was a bit of activity from
someone else doing very similar things. Perhaps it was you. What we
really need is a coherently packaged distribution. I don't mean CDs.
I just mean something you can type "make" against. The hardest thing is
getting all the libc issues resolved. It's annoying in the extreme when
things that compile on one of Linux or BSD won't build on the other one.

The problem is not the Netscape version. The bus error problem was
fixed by v4.03. The problem is your libraries do not match those
required by Netscape. Go to Netscape's directory and type # ldd netscape
This will give the dependencies. You either need an OS upgrade or you
can make a /usr/local/lib/netscape directory and put the needed
libraries there. By default Netscape will look there without doing
anything special. This 'old' fix may do the trick if you are using an
old version of libc5. Give it a try if all else fails.

Without knowing which version of Linux you use this is the best I can
do.

I finally found out, it was linked with /proc/config.
I can nowadays build the kernel without any problems, if I do not
include /proc/config in the kernel.
I still do not understand what is /proc/config use for, but that's too
bad.
