Same to all. Mine was spent with family, which was interesting as Christmas 
always is.

I currently have my linux (mdk 8) box running as a gateway with my alcatel 
frog modem and linked to the other machines.

Basically, you'll need to do the following as root:

[you at yourhost]# echo 1 > /proc/sys/net/ipv4/ip_forward

and in /etc/sysconfig/network

FORWARD_IPV4=true

Then, all you need to do is delete your default route:

[you at yourhost]# route del default

And add a new one that reflects the device name used by your network device 
(for me this is PPP0) :

[you at yourhost]# route add default dev ppp0


I'm guessing you're using NTL as a cable provider? Try this HOWTO:

I run it on linux, win2k, winxp, and solaris.

To run on linux, download it from http://setiathome.berkeley.edu/unix.html 
and issue a

[you at yourhost]# tar zxvf setiathome-packagename.tar.gz

Then all you need to do is run the executable. I run it using an hourly 
crontab to ensure that if for some reason it's not running, it starts 
correctly. Seti recommend that you don't put it in a while(1) loop as if 
for some reason the master server is unavailable, you'll keep pounding the 
server heavily. Remember that you do have to run it interactively the first 
time in  order to setup your account, so make sure that you do run it from 
the command line the first time.

If you want to watch how you're doing under X, and you don't want to cause 
seti to take precedence over everything on your machine, use the following:

[you at yourhost]# ./setiathome --nice 19 --graphics
[you at yourhost]# ./xsetiathome
