Replace xxx.xxx.xxx.xxx with the IP addresses of your preferred DNS servers. Of course if you are using DHCP this should be created automatically when you are issued an IP address.[/b]

I use DHCP, and the file is there. However it has the search part after the 2 DNS servers (both of which i can successfully ping). I still get "an error occurred while trying to connect to www.anything.com.

and when i disable it (ics) in mandrake control centre, i can use the internet again (this post written in Konqeuror) :confused:

I'm sorry, I missed the key part "ics". Sorry I am not familiar with this in Mandrake. I assume it is just a graphical configuration for IP-MASQ, something I have always done manually. Sounds like it must not be adding the proper iptables (firewall) rules.

oh, sorry about that, it's called connection sharing, it's a graphical thingy (nice technical term there ) that lets you share an internet connection over a network. You can do automatic configuration, or do it manually (i'll get some screenshots).

Not having used this tool I would use the configuration example in your second screen shot. What it appear this *should* do is configure your machine as a DHCP server, it should also configure it as a DNS server, it should also configure it as a router/firewall (IP-MASQ/IP-FORWARD using iptables).
Now if this is what you did, and you can ping outside machines by address and not by name then that would indicate that it has not properly configured your machine as a DNS server. If your machine is configured as a DNS server you should have "nameserver 127.0.0.1" in your /etc/resolv.conf and you should have your DNS service started.
However, you *should not* have to configure your local machine as a DNS server, you should be able to point to your providers DNS server which should configure your DHCP clients with your provider's DNS server addresses. If using your provider's DNS server your ICS server and client both should be pointed to your provider.
But like I said, I have never used this utility so I don't know for sure how it works other than I'm sure it does the same things I do manually.
Things you could do to test. Use "ping" on both your server and your clients to see if you can reach by address a machine on the internet. Then try to ping by name. If you can ping by address then your IP-MASQ is working properly. If you can not ping my name then check the resolv.conf on the server, check the resolv.conf on your clients (or "ipconfig /all" in WinNT/2K/XP, winipcfg in 9x).
If it appears your resolver is configured properly then it may be a firewall issue. iptables may be configured to block port 53 traffic (DNS). Check your "rc.firewall" in this case (or post it).
