Internet/lan-only lan working

[Nejko]

I have reinstalled my fedora core 4 like toturial said on howtoforge. I get lan working with eth0 but internet is'nt working. I have router. Server's IP is 192.168.2.103 , my ip and the newtork is 192.168.2.1. How to configure eth0?

THNX !

[till]

Do you have a dedicated router or is your server the router?

[Nejko]

dedicated router, with 4 computers on it. hod do i know that internet is not working? yum update gave me that:

[root@localhost ~]# yum update
Setting up Update Process
Setting up repositories
Cannot find a valid baseurl for repo: updates-released
[root@localhost ~]#

and i can ping only computers in my network.

and here is my eth0's config:

DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.2.103
NETMASK=255.255.255.0
NETWORK=192.168.2.1
BROADCAST=192.168.2.255
ONBOOT=yes
MII_NOT_SUPPORTED=yes

what's wrong with it?

thanx for your answers!

[till]

In your eth0 config the gateway is missing.

[Nejko]

what do i add then?

[till]

Not shure how to do it in FC4 as i have currently Ubuntu installed.

Please post the output of:

netstat -rn

If the default route does not point to your gateway, you can set the routing on the commandline with:

/sbin/route add -net 0.0.0.0 gw 1.1.1.1 eth0

where you have to replace 1.1.1.1 with the IP address of your gateway.

[Nejko]

[root@localhost ~]# netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
[root@localhost ~]#



/sbin/route add -net 0.0.0.0 gw 192.168.2.1 eth0

network restart.. still nothing :(

[till]

Ok, seems that your gateway is not set.

Do you have a file: /etc/sysconfig/network

and in the file the setting:

GATEWAY=1.1.1.1

where you have to replace 1.1.1.1 with the internal IP address of your router (gateway).

[Nejko]

i have set the file to:


NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.2.1



still not working :(

[Nejko]

got it now workin' with my ppoe gateway :D:confused:

thanks for all your help

wtf?! i'll get crazy :(

[falko]

Does ping -c4 64.233.183.99 work? What does /etc/resolv.conf look like?

[Nejko]

[root@localhost ~]# ping -c4 64.233.183.99

[root@localhost ~]#

; generated by /sbin/dhclient-script

my eth0:

NETWORK=192.168.2.1
BROADCAST=192.168.2.200
GATEWAY=192.168.2.103
ONBOOT=yes

hope that helps :S

[falko]

Why don't you use

DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.2.103
NETMASK=255.255.255.0
NETWORK=192.168.2.0
BROADCAST=192.168.2.255
GATEWAY=192.168.2.103
ONBOOT=yes?

[Nejko]

i replaced, and restarted network, but still:


[root@localhost ~]# ping -c4 64.233.183.99

[falko]

Is your gateway really 192.168.2.103? Because that's the same IP address that you use for IPADDR...

[Nejko]

dunno :confused: here's two screens from my ruter:

hope that helps..

[falko]

Your gateway is 192.168.2.1.

[Nejko]

well, i have like that:


DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.2.103
NETMASK=255.255.255.0
NETWORK=192.168.2.1
BROADCAST=192.168.2.255
GATEWAY=192.168.2.1
ONBOOT=yes


but it's not working :S is there any other network config file i should edit?

[falko]

Please change
NETWORK=192.168.2.1
to NETWORK=192.168.2.0 and restart the network. If it doesn't help, reboot your server.

Also have a look at this page: http://www.subnetmask.info/

[Nejko]

now it's works. thnx for all your help! i can ping my other server in germany, i can acess to fc4 ftom my lan...

edit: yum update still doesn't work :(

but yum update:


[root@localhost ~]# yum update
Setting up Update Process
Setting up repositories
Cannot find a valid baseurl for repo: updates-released
[root@localhost ~]#

it's mybe becouse i canceled it one time?

[falko]

What does /etc/yum.conf look like?
Maybe these links help you:

i'll just format and reinstall fedora :D i guess it will be easier. i'll post here what will be then :) thanx once again for Your help

edit: same sh*t :(

[falko]

I found this page: http://utcc.utoronto.ca/~cks/space/blog/2005/07/20/

So please post your /etc/resolv.conf here.

[Nejko]

search localdomain

just that in it...

[falko]

Change it to

search localdomain
nameserver 145.253.2.75
nameserver 193.174.32.18
nameserver 194.25.0.60

[Nejko]

still same... can u try? i sent pm to you couple hours ago...

not working....

Falko is currently in hollidays, laying at the beach with his girlfriend :) So better post to the forum.

[Nejko]

fc4 said that network is unreachable or something similar :) :rolleyes:

edit #1: connect: Network is unreachable


look at your inbox

[till]

Is this problem only related to yum or cant you connect to the internet at all. try e.g. "ping www.google.com" or "lynx www.google.com".

Please post the oitput of the command "ifconfig".

[Nejko]

[root@localhost ~]# ping -c4 www.google.com
ping: unknown host www.google.com

Are you sure you changed /etc/resolv.conf? Please double-check.
Please post the output of route -nee

Also, does ping -c4 64.233.183.99 work?

[Nejko]

[root@localhost ~]# route -nee

[root@localhost ~]# ping -c4 64.233.183.99

i'm sure for resolv.conf.. it's like that:

search localdomain
nameserver 145.253.2.75
nameserver 193.174.32.18
nameserver 194.25.0.60

:confused:

[falko]

Your system does not have a gateway. Please try tis again:
/sbin/route add -net 0.0.0.0 gw 192.168.2.1 eth0

If it doesn't help, reboot the system.

[Nejko]

heh, strange :) when it do command u posted, it works, but when i reboot it stops working again :)

[till]

This behaviour is normal, the routes get deleted when you reboot. Therefor you must set the gateway correctly to 192.168.2.1 as discussed in the prior posts.

Sorry, but i dont have an idea what else is wrong, i can only explain the reboot behaviour :)

[falko]

If setting the gateway doesn't work for you, you can put the line
/sbin/route add -net 0.0.0.0 gw 192.168.2.1 eth0 at the end of the start section in your network init script in /etc/init.d.
Then you should have an internet connection even after a reboot. :)

[Nejko]

[falko]

This means that the quota package is already installed.

[Nejko]
