hey guys,

i have debian 3.1r0a runnig, and the network is configured as below:

debian:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:02:44:24:4E:F0
inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0

check if you have firewall installed. Do

apt-get remove iptables

and check for other firewall on your system.

check your /etc/resolv.conf file and see if it gets proper DNS server IP.

You need to setup the gateway in /etc/network/interfaces like;

iface eth0 inet static
address 192.168.1.103
netmask 255.255.255.0
gateway 192.168.1.61

If you want to get hostname resolution, such as ping cyber then you need to enter the details in /etc/hosts in the form;
192.168.1.61 cyber

Can you ping Google when you use the ip-address of the Google server ?? So, does 'ping 216.239.59.99' work. If so, you are connected to the Internet, but your machine can't resolve the ip numbers from the DNS names. In that case you need to specify a DNS server in the file '/etc//resolv.conf'. It should look something like this:

Code:

search
nameserver      xxx.xxx.xxx.xxx
nameserver      xxx.xxx.xxx.xxx

You have to specify the ip-adress of the name server(s) where the xxx.xxx.xxx.xxx are.

Good luck
