Hi,

that idea about using cygwin as an X server. does anyone know of
any idiots guides to getting that working? ive been using vnc but i 
would like to try that idea, as i use cygwin most of the time for rxvt!

what are the pro's and cons of this way over vnc?

Two ways you can do this:

1)	Install an Windows based X server on the Win95 box and get a
Knoppix 
"session" running on it.

2)	Use Internet Explorer under Win95, and configure Knoppix as a
router.


_Requirements for both solutions_
Both of the above will require an RJ45 crossover cable to connect the 
two machines and each machine to have an IP address on the same subnet:

   Knoppix               Win95
192.168.0.1 -------- 192.168.0.2


_Solution 1 method_
- X server running on Win95 (cygwin is a good free one)
- Start an X session on Knoppix to forward to the Win95 X server:
   `export DISPLAY='192.168.0.2:0.0'; startx &`
- Open a web browser on the Windows machine just as if you were sat in 
front of Knoppix.

_Solution 2 method_
- Configure Win95 to use a default gateway of Knoppix (192.168.0.1)
- Configure Knoppix to act as a router (between ethernet and dialup) 
`echo 1 > /proc/sys/net/ipv4/ip_forward`
- Configure Knoppix to do network address translation (NAT) so that 
connections to the Internet from either machine go out on a single 
public IP address: `iptables -A POSTROUTING -o ppp0 -j MASQUERADE`


Hope that helps.
