Summary: I have ran system-config-network output says that it can't determine an IP. Do I need to replace the NIC?
#system-config-network
So I ran the command, and a network configuration window appears with tabs:
1.Device
In this tabe the device eth0 has an inactive status. I clicked activivate and there is a "Determining IP information for eth0...." message that eventually changes to "Determing IP information for eth0...failed" And an alert at the top "Cannot activate network device eth0!"
in a terminal/console window post the output of 'lspci | grep -i ethernet' and 'ifconfig eth0', note you might have to use 'su' to be root to run these commands.
we would need to know how your network is setup. do you use a router? or straight to a dsl/cable modem? if you use a router it should work fine if you specified that it uses DHCP somewhere. if you connect straight to the modem you would have to use a 'pppoe' connection.
***Summary: In response to running through cable modem? YES Output for lspci | grep -i ethernet and ifconfig eth0
I am running through a straight cable modem. So I assuming that I need to use 'pppoe connection.' -In other words I 'll be reading about that until I hear from you again. And of course this is prior to me running 'lspci | grep -i ethernet' and 'ifconfig eth0'. Whose out puts are:
***I am using a kvm switch so I don't have a way to copy and paste this output the box that I'm using to write this reply is a windows box.***
yes if you connect directly to the modem youll probably need a PPPoE connection. i dont use fedora core so i dont know what tools it has. open a console as root and type 'pppoe' and press tab afew times to see what similar commands it has. if it doesnt come up with any search around here in the fedora forum for PPPoE or on other fedora cor forums.
good luck
is there other pppoe commads? usually youd have to run something like pppoe-setup or pppoe-config. typing pppoe then tab afew times will list the others with similar names.
can you do 'whereis pppoe' to find out where it is installed and look for its configuration file, maybe in /etc/. open it to see if there is a template or instructions on what to change to get your pppoe connection working.
also look in the GUI and even the tools you used before for PPPoE connections.
Whoah - call your ISP and ask if you need to use PPPoE. Most DSL services require it, but most Cable service providers, such as mine, do NOT use PPPoE for authentication.
Remember: Cable is not DSL. DSL runs through your phone lines and Cable comes with with your TV signal.
