Network interface problem 2 years 32 weeks ago

Hi

i have replace a NIC card on solaris 10 when i give the following command ifconfig -a it just show the lo0 (only loop back with inet 127.0.0.1)

when i give the following command to config the interface, ifconfig elxl0 plumb ifconfig: plumb: elxl0: no such interface

please help me to solve the issue

What layer does ifconfig operate at when setting a MTU. Does it set the MTU for the physical device (Network Interface Layer) or the MTU of the packet (Internet Layer)?

By executing

Code: ifconfig eth0 mtu 1300 it leads me to believe this is causing the Network Interface Layer to be restricted because an interface must be specified.

So this has been driving me nuts for a good couple of hours, so I thought I'd ask about it here (let me know if there's a better forum for this question).

I am already a little bit familiar with Linux distros like Debian or Ubuntu (yeah, very similar) but I wanted to try Red Hat based - CentOS 6.2 . I have installed it on my Windows 7 host in virtualBox and tried to play with it a little.

I have same across a small problem, namely : the default eth0 interface is down by default.

To get the IP address I use ifconfig and do some string manipulation.

Welcome to Arch.  Two things in addition to Graysky's link (TL;DR version of the link: It is probably not called eth0:)1.  ifconfig is depreciated.  The preferred command now is a sub command of ip.   The command is: ip link2.  ifconfig only displays the interfaces that have an address.  To see all the interfaces, use ifconfig -a   or, of course, i

Heya, folks.

I'm trying to grok a problem I'm having with an embedded machine. I'm pretty sure I can track down the larger problem, but I came across a usage of ifconfig that I don't understand, and I'm pretty sure this is the command that is failing.
