Problem with changing IP

My IP address given by our router doesn't always seem to be the same. So today when I booted gentoo, it wouldn't boot because my IP was 192.168.0.3 whereas the line in /etc/hosts was:
192.168.0.2 tux tux.homenetwork

So if my IP changes how am I supposed to be able to boot given that I set up /etc/hosts manually for the old IP?

So your router is using dhcp?
Most routers can be changed to fixed IPs - so go to your router configuration and deactivate dhcp - then set your local lan ip to a fixed number.
If you want to stick to dhcp then you can simply delete this line from your /etc/hosts just leaving the "127.0.0.1 localhost"

Indeed, you have to choose whether or not you want a fixed IP. If you do not care about the fixed IP then you can just add an alias to 127.0.0.1 and drop the line that reads "192.168.0.2 ..."
Your new line would be this:

is it possible to just write up a script to change your hostname and ip in your /etc/host by sed and then add it into your net.eth0 at /etc/init.d/ so that every time when it starts it would update your /etc/host.

I've written similar script before but just to add hosts for other remote machines which were dynamically connect for my own convience. Then I've putted this script as a cron job so that instead of checking its' ip all of the time I can connect it just by different names. Just my 2 cents.

when i used to use windows
i'd put all the ad sites in my hosts file, and set it to 127.0.0.1 so whenever the broswer/system tried to retreive an ad, it would look at 127.0.0.1 - and since there isnt anything there i had no ads

try the same.

rather then doing
[code]
127.0.0.1 localhost tux
[code]
which gives you the gnome-host error thing
try this
[code]
127.0.0.1 localhost
127.0.0.1 tux (or whatever name u want)
[/code]

tell us if this works..

Well, I did actually make a startup script that would fix the file. Problem was I kept on powering down manually since it would freeze on logon for gnome, so it would no longer boot quite right.

So I started over and did a stage1 install (wasn't worried about trashing the disk; it's a new system so nothing important was on there). Now I'm using KDE and there's no problem like before as it doesn't use the /etc/hosts file.

Though I had tried using gnome at first when I did the new install but pygtk wouldn't compile (kept on looking for libGL.la in the default directory instead of the directory it's in if you do "opengl-update nvidia").
