Internet connection

[Guest]

Hi everybody!

I'm really new with kubuntu.. And I'm having many problems to get an internet connection...

I've tryied by the normal way:
- Go to <<edit connection>>, new connetion, and then write my manual IP configuration (just like windows)
In this case, nothing happened, there is no connection, if I do any ping to any IP, also my gateway, the answare is: <<connect: Network is unreachable>>



I've thinked that maybe there is some problema with my driver
however (like i'll explain later) i discover there isn't.



After this disaster i've tried to solve the problemes by the terminal:
I've write <<sudo ifconfig eth0 172.16.0.8 netmask 255.255.0.0 up>> and <<sudo add default gw 172.16.0.1>>

after that the answer of <<ifconfig eth0>> is:

eth0 link encap:Ethernet HWaddr 00:23:54:62:b9:__
 inet addr:172.16.0.8 Bcast:172.16.255.255 Mask:255.255.0.0
 inet6 addr: fe80::223:54ff:fe62:b926/64 Scope:Link
 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
 RX pakets:154 errors:0 dropped:582287922 overruns:0 frame:0
 TX pakets: 86 errors:0 dropped:0 overruns:0 carrier:0
 colisions:0 txqueuelen:1000
 RX bytes:15421(15,4 KB) TX bytes:133994(13.9 KB)
 Interrupt:216 Base address:0xc000

and the answer of <<route>> is:

Kernel IP routing table
Destination  Gateway    Genmask    Flags  Metric  Ref  Use  Iface
172.16.0.0   *       255.255.0.0   U   0     0   0  eth0
default     172.16.0.1  0.0.0.0     UG   0     0   0  eth0

If I make a ping to my gateway (172.16.0.1) there IS answer.
Also If I make a ping to my DNS adress there IS answer
(so it can't be a driver problem)
But if I make a ping to www.google.es, there is NO answer..



So........
....it may be a DNS problem
¿How I can configure them by the terminal?

and....
.... when I restart my computer (kubunutu it's installed no live CD) all the ifconfig are erased...
¿How I can configure the net properly?



Thanks for you attention!!

Re: Internet connection

When you use DHCP, your system automatically obtains the DNS entries it needs. When you specify a static IP, it doesn't. You have to entrer the DNS in your resolv.conf file. See my post here on how to setup your computer with a static IP.

Re: Internet connection

IIRC /etc/resolv.conf will be reset after a reboot, so you will loose DNS servers (at least in 8.04 it did). If this is the case, you can add dns servers in /etc/dhcp3/dhclient.conf

In dhclient.conf look for a line with "prepend domain-name-servers", unhash it and add dns servers (comma separated, closed by semi-colon).

If you use dhcp it will. With a static IP it shouldn't. The dhclient.conf file does not run unless using dhcp.
