I am running a home LAN with one linux machine (FC3 running Samba 3.0.10-1.FC3), and two windows machines (WinXP and Win95).

Both, the linux box and the WinXP box have separate cable access to the internet. Both also share a LAN connection which is working well. File & printer sharing and messenging is good.

I have now added a Win95 box (so that my son can play his old Win95 games on it) and I would like to have it access the internet through my linux box. At present, I can see Win95 box with samba, and he is able to see the linux box through windows.

Static address of linux box: windy: 192.168.0.1
static address of WinXP box: broca: 192.168.0.2
static address of Win95 box: fishstick: 192.168.0.3

Here is the samba configuration from my linux box:

Is is possible (and safe) to allow the Win95 box to access the internet through my linux box? I would like to be able to put safeguards on where he accesses, and would like to have a log of where he actually goes when surfing.

I am not sure what to do, and do not want to mess up my samba configuration (again) trying on my own. I appreciate any help offered.

First off, samba has nothing to do with internet access. Samba is a program that allows computers to share files. You may want to do a search on turning linux into a router.

If you don't already have 2 Network interface cards in the linux box, you should consider getting one. In order for the linux router to pass internet access onto your win95 machine you need to run software like "iptables". I'm sure there are many easy alternatives to configuring the router, I just cant think of a suitable one right now.

So do a search "turning linux into a router" and something should come up, its been answered many times. good luck.

Thank you for educating me more about samba. I use samba to file and print share with the Win95 and WinXP boxes, and obviously made a mistake in thinking that I needed it for sharing internet access as well.

I have two nics in the linux box. One (eth1) connects to the cable internet. The other (eth0) connects to the home lan. I also have iptables running, and have put the output from iptables-save below:

Excusing the samba part - which you set me right on - is it possible for the Win95 box to access the internet through the LAN? If so, how would I do this? Thank you for your help.

I have managed to load and run squid 2 on my fc3 box and adjust my iptables so that my win98 box can access the internet. I used the instructions from: . www.linuxhomenetworking.com/linux-adv/squid.htm to set up squid-2

I also set up some rudimentary parental filtering on the win98 box by removing IE, downloading Firefox, and installing the blockxxx extension.

I have downloaded and installed squidGuard (squidguard-1.2.0-2.1.fc3.rf.i386.rpm) but I cannot figure out how to configure it properly so that it runs with squid 2. Can anyone help me?
