[GLLUG] ubuntu autochanging of /etc/resolv.conf and 192.168.1.64

[Scott Harrison]

Hi, 


Here is my current situation.  I am booting from
ubuntu live cd desktop version 6.06.1.
Please see my silly perl scripts below, and
help me find a better way! 


If I don't do this,
perl -e 'while(1) {sleep(1);`echo "nameserver 35.8.2.41" > 
/etc/resolv.conf`;}' & 


I then, after a few minutes, wind up with this:
root at ubuntu:~# more /etc/resolv.conf
search domain_not_set.invalid
nameserver 192.168.0.1 


Also, I am doing this:
perl -e while(1) {sleep(1);`ifconfig eth0 192.168.2.1 netmask 
255.255.255.0`;}? 


because something in the system is auto-assigning
192.168.1.64 to eth0. 


I tried adjusting
auto eth0
iface eth0 inet dhcp 


to be
auto eth0
iface eth0 inet 192.168.2.1 


Also, for my LAN, I adapted various iptables commands
from http://www.tldp.org/HOWTO/Masquerading-Simple-HOWTO/summary.html
to help allow other LAN computers to access the internet.
I am wanting to use ubuntu live cd as a failsafe internet connection
tool for my LAN, but it seems cumbersome to
store/transcribe/thumbdrive/remixlivecd all those
iptable commands.  Is there a simple GUI or countably few
set of commands to do something similar? 


I'm still in a happy place, but I must face Darth Vader
(aka these bugs and issues) again, and this mailing list
is my only hope.
