Fedora Core internet problems

[laforge]

Ok i am running Fedora Core 4 on one of my computers everything works fine and dandy but my internet connections. When it checks everything in the beginning it says that it cannot obtain an IP address, i have it connect with a LAN cable but it doesn't seem to recognize it. Any help, i remeber something about kern but i don't know sweatdrop

[laforge]

Uh off first page bump sweatdrop

Home LAN or just connecting straight to the modem?

[laforge]

home Lan but it is connected through a few spliters to get here

[SkyeDarkhawk]

Do you have your home network set up for DHCP from your routers/modem?

I believe Fedora should have an auto-network configuration tool.. if not you should be able to set it to obtain an IP address automatically.


Also, have you tried testing your cable with another computer?

A good way to see if its linux or hardware is to boot up into windows and see if it can get a ip address.

I dont know how FC4 works but maybe the module for your network card is not being loaded or your system is trying to get a static ip address instead of dhcp?

Uh ok what is a DHCP and how can i see?

There is a Add new Device Type and has
Ethernet connection
ISDN connection
Modem Connection
Token Ring Connection
Wireless connection
and xDSL connection

when i do ethernet i choose "Realtek Semiconductor Co., Ltd. RTL-and a bunch of numbers" when i do there is "Automatically obtain IP address settings with dhcp" but it wont let me click it, it is greyed out, i have to statically set IP address.

Uh no maybe i should, let me get to that

EDIT: Yea the cable works

@Kysen: This is an old computer and it was able to go on the internet, i just ditched windows on it so nothing happened to the hardware

Ok new info, i looked into network config. and i found a ethernet connection that was using dhcp but it was inactive. So i try to activate it but it come up with this message "Cannot activate network device eth0!" "Determining IP information for eth0... failed"

eth0 is what my computer named that network config. i guess

eth0 is your first ehternet device, eth1 would be your 2nd.. etc etc

try typing "ifconfig eth0 up" followed by the program FC4 uses for dhcp.. on my gentoo systems i use dhcpcd

if "ifconfig eth0 up" reports a error saying "eth0: unknown interface: No such device" then that means the module for your nic has not been loaded.

[laforge]

Ok but where would i type "ifconfig eth0 up"?

[Kederaji Tajorn]

from a root terminal. start a system terminal window and use "su" to access your root account. FC3 is weird about some of the bash commands, and they have to be called directly from /sbin, so I'll assume FC4 is too. use the command /sbin/ifconfig eth0 up

ok this is quite big so i will just write it all.

ok that is all it says i don't know what any of it means though sweatdrop

[Kysen]

Ok you have a nic working just dhcp is not working at boot.

try this command "dhclient eth0" if that gives a error try "dhcpcd eth0"

Edit: please add the error messages (if any) you get with those commands

[Alcoholic Hero]

maybe you just have the wrong cable or your cable is busted.

ok i had to do that su and sbin thing but i came with this

I am guessing and the 255. is my IP address, looks weird to me
