Fedora 6 Network Problems

wizard91 · 5 Jan 2007 at 17:12

Hi,

Installed core 6 works real sweet apart from connecting to the network and web which does not work.

I have an adsl router (netgear) with four other machines connected through it.

I have set up manually.

Address: 192.168.0.XX
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.XX (this being the router setting)

Tried to ping the router but cannot be reached.

Any help appreciated.

Hmm, sure the device is up in ifconfig?

wizard91 · 5 Jan 2007 at 17:19

Ok, but how do you get to your iConfig? Im a new to Linux by the way lol.

Una · 5 Jan 2007 at 17:20

Run it from a terminal.

alex@nop:~$ ifconfig

And paste the output here.

Setup looks OK, assuming that is how your LAN is set up, unreachable straight away usually means a configuration problem though.

Any firewall running, can you ping other machines on the network?

Any other machines listed when you type arp at a terminal, does the output from the ifconfig or route commands tally with your setup?

Open up terminal type in if config like this:

[rasc@localhost:~] $ ifconfig
bash: command not found.

I am a total newb at this, obvious I know :+)

K its obviously not added to your $PATH in fedora.

Try sudo ifconfig or /sbin/ifconfig instead.

Need to be root;

su -
ifconfig

wizard91 · 5 Jan 2007 at 18:17

I have found the the ifConfig file, but I dont know how to get it open? Anyone know?

in a terminal, type:

su followed by the root password
then /sbin/ifconfig

.. and see if there is an entry for "eth0"? You should see something like this:

Code:

[root@mailbkp /]# /sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr 00:50:04:38:D4:51

Okay got that, cannot paste it up as I have no way doing so but it basicaly has the same as you have posted except I have an eth0, eth1 and lo.

wizard91 · 5 Jan 2007 at 18:37

I have also disabled firewall to see but no change.

wizard91 · 5 Jan 2007 at 19:08

Moving on I have deactivated eth1 and pinged 192.168.0.1 which gives results but still no connection to the net??

deano · 5 Jan 2007 at 19:09

at the prompt do cat /etc/resolv.conf

and tell us what that returns.

have you set up the right network device with a static address, if you have eth0 and eth1 then you got 2 network connections. Have you not got DHCP off the router?

wizard91 · 5 Jan 2007 at 19:22

Ive got windows server running, and I can see that, and browse all the server directories, so the network is obviously running. But I just cannot get to the internet.

deano · 5 Jan 2007 at 19:26

where you did /sbin/ifconfig at the prompt do

cat /etc/resolv.conf

and tell us what that returns.

you should your dns server in there, if there not then add them in, either through the GUI using the network config tool, or on the commad line by using su to get to root then editing the file using either nano, joe, gedit or vi.

M0KUJ1N · 5 Jan 2007 at 19:39

what output does (as root) /sbin/route give?

You may have to add a default gateway using the route command although we wont know until we check

EDIT: Nevermind.

thought he could ping his router^
can you ping :-

83.223.98.170

Ping as requested and got:

"Network is unreachable"

Which is strange because I can see all the other machines on the network and browse the server drives.
