Can not install ipmasq in ubuntu 9.10

[tuga]

I can not install ipmasq in ubuntu 9.10. This is what I get:

root@amd:~# apt-get install ipmasq
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ipmasq is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package ipmasq has no installation candidate

I need ipmasq for internet connection sharing...

Can some one please help.

Thanks

you don't need the ipmasq program to share the internet, it is last updated "Feb 19, 2000"

instead you can set the masquerade rule like below (replace eth0 by your internet interface) and enable forwarding in the kernel

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables-save
sudo sysctl -w net.ipv4.conf.all.forwarding=1

Still don't have internet on the other pc...
The ubuntu pc is connected to the internet via eth1. The other pc (windows xp) is connected to ubuntu pc via eth0. Ping between both PCs is ok.
I also tried to have ICS with firestarter but that also did not work.

This is the log:

tuga@amd:~$ sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

I am having the same problem, friend, as I have not yet been able to successfully activate internet connection sharing on my new karmic 64 bit install. Numerous how-tos include using ipmasq.

Finally, here is what will work on karmic:

sudo apt-get install network-config dhcp3-server gufw

network-config is a hidden gem in the universe repository that is launched from the command line (no menu item appeared at installation.) Also, it is simple and works well for configuring network interfaces (wired or wireless) and internet connection sharing.

Further, I needed dhcp3-server to assign IP addresses to my internal network (2 other PC in my house, kids and TV room laptop.)
Details on configuring it are at: https://help.ubuntu.com/community/dhcp3-server
