Trying to get my Linux box to be a gateway for my Win95 box...need help

Post by Ben Greea » Mon, 16 Feb 1998 04:00:00



First of all, thanks to all who have offered me advice so far...

I now have ethernet talking and am trying to get over the final
hurdle (I hope!)

I can telnet to linux box from win95 box, but I can't telnet to the
outside world, even though linux will, and I used IP addr.

I've compiled the kernel with IP/Fowarding (in the kernel, not a
module).

I have the win95 box set with 192.168.1.1 as it's gateway,
and if I telnet to that addr from the win95 box, then I get
my linux box and can log in...

Heres some diagnostics that might help...

Have you added the IPmasq rule?

eg:
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.1.0/24 -D 0.0.0.0/0

I hadn't, but now I have.  Read that whole IP-Masquerading thing too..
It
still doesn't work..and the worst part is I have no idea which part is
failing...  Fowarding?  Perhaps I didn't compile the kernel right?  (I
followed all the directions....)

Does anyone have any ideas on how to test things?  Is there a way to ask
the fowarder (which daemon is that anyway...the kernel itself?) to dump
a bunch of stuff into a log?

The only command I've had give me any kind of failure notice was
depmod

Quote:> shamen:/etc/rc.d#   /sbin/depmod -a

*** Unresolved symbols in module /lib/modules/2.0.30/fs/smbfs.o
*** Unresolved symbols in module /lib/modules/2.0.30/fs/vfat.o

*** Unresolved symbols in module /lib/modules/2.0.30/block/linear.o
*** Unresolved symbols in module /lib/modules/2.0.30/block/raid0.o
shamen:/etc/rc.d#

I doubt these are good things for it to be saying..but they don't seem
to fatal...

Also, aside from the mini-howto, any other docs that might be helpful?

Thanks again,
Ben

Trying to get my Linux box to be a gateway for my Win95 box...need help

Post by James Ros » Tue, 17 Feb 1998 04:00:00


I have IP Masquerading running on my PC box and have no problems connecting
to the outside world from any of the other machines on my ethernet.  I just
followed the IP masquerading directions and had no problems.  It is a good
idea to compile the latest kernal 2.032 so you can avoid all the patches
etc...

did you add the commands

/sbin/depmod -a
/sbin/modprobe ip_masq_ftp
.
.
.
(there are ones for cuseeme, realaudio etc)
before the ipfwadm commands....

Hope this helps

Are you running Redhat? I've seen several posts about IP Forwarding
having to be enabled at boot time by a command along the lines of
"echo 1 > /proc/net/ip_forward" though I am not sure of the exact
destination in the /proc filesystem.

I trimmed pretty heavily, sorry if I messed up any attributions...

Which kernel are you using? The IP Masquerade Resource
(http://www.wiznet.ca/~ambrose/) suggests 2.0.33 Since I am running
RedHat 4.0 which came with 2.0.18, I downloaded 2.0.33 and compiled in
all the recommended options for IP Masquerade. It worked without
having to do the "echo 1", which I too have heard of.

I suppose that I got lucky, but IP Masquerade worked the first try for
me. Cosmic justice, perhaps? To make up for the nightmare I endured
setting up my ethernet cards? :-)

The latest kernel is 2.0.33, unless they've released 2.0.34 - see
ftp.kernel.org for the source.

The depmod errors may be because you didn't clean out your modules
directory before rebuilding your kernel. Try deleting everything from
/lib/modules/whatever-kernel-version (or just rename the directory if
you're the paranoid type :), then cd to /usr/src/linux and run "make
modules-install".

For your firewall and IP-masquerate/gateway questions, take a look at
http://www.wolfenet.com/~jhardin/ipfwadm.html for a tool that may make
managing things easier for you.

1. Trying to network a Win95 box to a linux box

I am pretty new to linux

I built a separate computer for linux. Viper MB,AMDK5 75Mhz,16Meg
Ram,3.2Gig Maxtor HD. I share a Monitor, Keyboard and mouse via a switch
box on my desk with my win95 box.

My goal: I would like to set up these two computers (linux-win95) so I
can share files between the two as peers. I now have a modem in both
computers, but I would like to use the Linux box as my connection to the
internet and maybe run the Modem as a Proxy for both computers (is this
right)?

So far I've been able to set up a connection to my ISP and browse the
web (Lynx) and get my mail (fetchmail) on the linux box. Things are
working pretty good so far.

A have two pci network cards I would like to use for the network. They
are N32PCI Combo Cards. I can configure the card in the windows 95
machine with no problems, however, when I boot my linux box, I get the
error:

Warning: Unknown PCI Device (8e2e:3000) see include/linux/pci.h

I am using the pre-complied kernel of Slackware 3.3 Kerner v 2.0.30.

I have been all over sunsite.unc.edu/LDP and I just don't understand too
much of what they are telling me.

I'm pretty sure I have to recompile my Kernel for the PCI Device, but
that is all I know.

I started this project 2 days ago and haven't gotten much sleep. 14
hours to get my ISP DNS to work (it all came down to one word in
resolv.conf defaultroute).

I have read some information about samba (mostly questions) is this a
good thing?

I will take advise from anybody.

Thanx for your time,

Jeff
