As you can see there is no default gateway setup in your routing tables. You are going to have to setup a default gateway in order to get out.
Can u point a place with a configuration file ? No idea where it is :(
/etc/network/interfaces is the usual place
Hay Zacard, I hope you are well, In regards to your question
You are Experiencing this because the more technical distros require you to manually bring a interface up or down, or set services to load on boot. your best option is to set a static ip.Quote:
Can u point a place with a configuration file ? No idea where it is
set the ip in a range between say 192.168.1.1 and 192.168.1.20, but make sure that no othere computers are using these ip addresses at the time so you can be sure you are not trying to use an already allocated address , (just turn the others off whilst you do this) Don't worry your other pc's will get a different ip when they boot again.
Over the many distros of linux there are different locations that a static interface can be configured, I know of to that might help you.
Backtrack /Gnome :
For example If you wanted to statically assign Eth0 an ip or gateway etc... you would type this in the interfaces text doc.Code:vim/etc/network/interfaces
Save thatCode:auto eth0
iface eth0 inet static
address 192.168.1.16 (your ip)
netmask 255.255.255.0 (netmask)
gateway 192.168.1.254 (your gateway)
Then,
edit this to what your DNS Server is, most likely your routers IP.Code:vim/etc/resolve.conf
Code:nameserver 192.168.1.254 (your DNS server Ip)
Now,
.Quote:
etc/init.d/networking restart
For Centos/RH :
To make Eth0 for exampleQuote:
vim /etc/sysconfig/network-scripts
Inside the doc use this formatQuote:
vim ifcfg-eth0
thenQuote:
DEVICE=eth0 (the device int)
ONBOOT=yes (if ya want to run on boot "yes" if not "no"
TYPE=Ethernet (type of int) (optional)
BOOTPROTO=static (if your adding a static ip "static" if ya want DHCP to figure it out use "dhcp"
IPADDR=192.168.1.1 (static ip not needed if using dhcp)
GATEWAY=192.168.1.254 (router ip)
DNS=192.168.1.254 (prob same as gateway ip)
NAME="my eth0" (optional)
I hope this helps.Quote:
service network restart
Thanks
Ben
This is good and this is the address that you are going to need to set as your default gateway.Quote:

ONBOOT=yes
BOOTPROTO=static
IPADDR=<ip address you assigned this interface>
GATEWAY=<the ip address you can ping that is the gateway>
