No ifconfig ?

I just installed fedora core2 and I cannot run ifconfig. not even if I su.
I am new to linux. Is there some directory i have to switch to that containes the 'ifconfig' tool ?
I cannot make my network connection work either. I have used the gui tool, and I have tried putting the nic on dynamic, and static
and have had no luck with either. I dont understand why I cannot surf the web. I put in the ip address, the subnet, the gateway and the dns servers. but I cannot surf the web. This is really bogus.
I need help.

Hi joncolby,

try /sbin/ifconfig

if that does not work, then run locate ifconfig

this should tell you where ifconfig is

ok
I ran locate ifconfig
and it said it was in the /sbin directory
but when I move there and then try to run ifconfig
it says

bash: ifconfig: command not found.

I run fedora core 2

I cannot even ping my gateway.
what the hell ?
I dont know where to begin. I am a new user.
should I just re-install linux ?
it is probably easier for me to do.  .... Hehehe... Look at me.... I am treating it like windows....hehhe..:-)

on your command prompt

/sbin/ifconfig

to run with just ifconfig do this

login as root

$]vim ~/.bash_profile

you will see a line like
PATH=/usr/bin:blah:blah

add to this line /sbin/ ... make sure any two entries are spearated by a :

logout and login

Try
su -
PATH=$PATH:/sbin

Now run  ifconfig -a

If it lists eth0, then you know your NIC's driver is loaded

To adjust your network configuration manually, look for a file called

 /etc/sysconfig/network-scripts/ifcfg-eth0

How to set it up depends on what kind of hardware and network you're connecting your computer to.
It may be more involved if you're connecting the system to a DSL modem for instance (needing to use PPPoE),
than if you're just trying to talk with another system on a LAN. Try pinging another host on the internet to rule
out DNS...

i.e.  ping 64.233.161.104

Hi Mysidia ,

changing PATH from the command line will only be good for that shell instance ... I would recommend changing the bash profile.

joncolby,

If the above stuff does not get you to a point that ifconfig will run, try this:

ping 127.0.0.1

This will try to run the ping command on your localhost IP address.  If this does not work, then TCP/IP networking was not installed, or for some reason is not working at all.

Thanks

ifconfig should work, as long as /sbin/ is in your path
(Which it actually is only for root)

As "normal" user try /sbin/ifconfig -a to get information of any networkinterface (including loopback)

if you do not have any NICs except loopback shown here, maybe your kernel does not recognize your nic. In this case have a look at google to find out, if your nic is supported or if there is a module, you cna load, but that is another story ;-)

looking at your posting above:
if you change into /sbin, then you have to run ./ifconfig as this ./ tells your shell to look for the specified command in the current directory and not in the directories listed in $PATH
