I just installed Linux on a system. It is the Red Hat Fedora version. It's pretty cool. I am trying to connect to the internet. I got my network installed correctly, and I went throught the internet connection wizard, but I am still unable to connect. I am totally lost as to how to connect to the net with Linux as this is my first time using Linux. Do I need to install certain protocols or is there some other stuff I need to do? I connect using a cable modem and my IP address is automatically assigned by my ISP. Can someone help me out. Thanks...

I am jealous.......

Would the Cable Modem providers HOWTO help?

do a thread search ... i typed in SB4200 .... and found all the help i need right here at LQ

Yea, I did a lot of searching before I posted, but there were only two posts on here about my cable modem which is a Toshiba PCX2600. Both of those threads were dealing with e-mail problems.

If youve just installed the router/cable modem, you need to det your router to obtain IP automatically, then unplug your cable modems power, and plug it back in for the router to get an ip/and or for the router to adjust to the new setting of network parameters.

Dont know if this will help, but thats with the ISP using DHCP, and your router obtaining an IP automatically, and your Linux machine using DCHP/BootP.

Unplug your modem, plug it back in, restart your computer, or re-bring up your eth0 either way.

I tried unplugging it and then plugging it back in so that it could obtain a new address last night but that didn't work...

i will give it another shot...but if that doesn't work, do you think I should try a different ethernet card?

are you sure that youve went to , http://192.168.1.1 or the address of your router and configured it correctly?

the ethernet card may be broken, I guess.

What does ifconfig show?
what about pinging your internal computers/external also www.google.com?

I would encapsulate the problem before trying a new eth card.

I didn't do any configuration...I read the manual for my cable model and according to the manufacturer, if I am using the RJ45 connection to connect to the ethernet card in my PC and not the USB then the device works as a standalone device and I do not need to do any configuration or installation of drivers for the cable modem. This is what 'ifconfig etho' shows:

eth0

you ran the "redhat-config-network" command in a console? and when you installed you selected "use DHCP" right?

not sure which DHCP client fedora uses - there are a few possible ones - try running

dhcpcd

pump

or

dhclient


in a terminal as root... (they may be in /sbin)

You could try recycling your ethernet conection if your dhcp client is set up:

/sbin/ifdown eth0
/sbin/ifup eth0

It was the ethernet card, I am actually on my third card now, but when I put in this card and tried to connect it came up like magic...no configuration or anything...thank you guys for all your help...
