eth0 Activates but no internet!
 

I recently installed Fedora Core 2 for my friend...

He has ONE ethernet controller connected to a router connected to his DSL modem...

Via DHCP, eth0 successfully determines an IP and activtaes ok

but he still has no connection to the internet... Mozilla says that he's not connected, and Gaim says the same thing...

And a when I installed Fedora Core 2 on my PC, i had a problem with my modem, which i fixed with (as root)
setserial /dev/modem autoconfig
setserial /dev/modem skip_test

So any suggestions?

Stumped!

thanks everyone!

Can you post the output of 'ifconfig', 'route' and 'cat /etc/resolv.conf'?

lol my friend spent an hour going from one computer to another transferring this data so go a little easy on him next time if possible ;-)

but thanks!

ifconfig...
Eth0 Link encap:Ethernet Hwaddr 00:0C:6E:5F:D5:CF

and then for route:

192.168.0.0 * 255.255.255.0 U 0 0 0 Eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
^^srry if it doesnt show up right, just try to match up the columns as best u can^^

and for the cat /etc/resolv.conf:
search localdomain

aight so that should do it... thanks for all ur help!

I just noticed in the ifconfig there's a laughing face, ignore that because its supposed ot be a colon and a capital D

sorry for the inconvinence, and thanks again for the help

It may be related to that Inet6 line. I don't have FC2 up right now but I seem to recall a check box to tell the system to use ipv4. That would be in the GUI tool which comes up with the command: redhat-config-network

Ok, you don't have a default gateway set.. Your route ahould have an entry "default" like this:
Second, you don't have an entry in /etc/resolv.conf for your nameserver. Like this:
This usually comes from invoking dhclient (I assume since you're using RedHat) or dhcpcd with the wrong flags.

Check your 'ps -aux' to see what flags it is being invoked with:
With dhcpcd -R prevents dhcpcd from replacing existing /etc/resolv.conf file. -G prevents dhcpcd from installing default routes provided by DHCP server.

The easy way to set this manually is to:
Whatever the real IP is of the router, and edit /etc/resolv.conf to contain nameserver entries for your ISPs nameserver. Or, whatever nameservers you are using.

homey, In FC2 there's IPv6 and not IPv4 so idk if theres a difference involved, but as for now im gonna put ur idea on hold and try Justin's idea. If that doesn't work, then i'll try yours, but or some reason Justin's sounds more promising. and THANK YOU

Justin - THANK YOU!!!

Since I wont get to try this out untril probably Monday when I go over his house (Betcha didnt know ur talking to a 15 year old all this time) any replies wont be submitted until then about this working... but to both of you, check back on Monday night IF YOU CAN, and THANK YOU guys SOOOO MUCH for all of your help. Just let me know if there's anything i can help either of you with, I've been using Linux since I was 8 lol

so, one last time, THANK YOU! and plz check back around Monday night.

IT WORKED!!!

I did exactly what Justin said and it still didnt work so i undid it and enabled IPv6 and it didnt work lol So then I did what BOTH of you said and it worked! lol thank you guys muchly!!!

:-)

I hope you figure it out!
