ifconfig problem

[Jerry Chen_2]

I use Red Hat 7.2
when I use /usr/local/bin/
start-pppoe to connect network

it will show /sbin/ifconfig : no such file or directory
But when I check
/sbin/ifconfig ,
ifconfig is there
And when I use ifconfig eth0 to check network ,
it will also show bash:/sbin/ifconfig : no such file or directory .
Can any one help me?

Hi,

What does ls -la /sbin/ifconfig return ?

[U.SivaKumar_2 · Accepted solution]

Hi,
Does eth0 exists under /dev
directory.?
Also check the permission of
ifconfig executable.

Hi Jerry,

seems like /sbin/ifconfig is a symbolic link which points to a no longer existing file. Check this out usine ls -l /sbin/ifconfig. This should show you where the link is pointing to.

Allways stay on the bright side of life!

Actually, ifconfig is reporting that it can't find some file or other that it needs. I ran into similar confusion with a script a few months back, the error message was like yours, /path/cmdname: no such file or directory, but the issue wasn't the command, but an argument passed to the command. Specifically, I had typoed the directory path to the file I was trying to pass to the command.

Hi
I use ls -la /sbin/ifconfig,it return
rwxr-xr-x ..................
and there is no eth0 in /dev/...
and ifconfig is not symbolic link ...

hi

I thought it's normal that /dev/eth0 doesnt
exists because its actually an alias to
your ethernet driver. Correct me if i am
wrong.

I think we're getting closer to the source of ifconfig's discontent.

What is the output of

# ifconfig

What it should be is something like:
eth0 Link encap:Ethernet HWaddr 00:90:27:91:DB:86
inet addr:aaa.bbb.ccc.ddd Bcast:aaa.bbb.ccc.255 Mask:255.255.255.0

Where eth0 et al are replaced by your network devices (modem, whatever)

If you are only seeing output for the lo, then the problem is probably that you haven't loaded the driver for your ethernet adapter, and will need to check why.

# service network status

should return the status of your configured network devices. If there are none, you will need to configure them.

Let us know!
