CentOS 5.5 network problem

Question

I have been made to install CentOS-5.5 on my desktop. The network is not working. These following are the outputs of various commands.

#ifconfig
lo link encap:local loopback
inet addr 127.0.0.1 mask 255.0.0.0
.....(goes on)

There is no other device other than 'lo' in the ifconfig output.

#chkconfig --list|grep -i network
networkmanager 0:off .... (every thing off)
network (2,3,4,5 on ; and rest of them off)

#service NetworkManager status
networkmanager is stopped

#service network status
configured devices:
lo
currently active devices:
lo

there is nothing in the /etc/resolv.conf file

regards

Solution

As you said, your network card is

00:19.0 Ethernet controller: intel corporation unknown device 1502 (rev 04)

This makes me think that, being seen as an 'unknown device', it's not supported by CentOS 5.5. Can you try a more recent CentOS version (CentOS 5.7 or CentOS 6.2)?

According to this, CentOS 5.7 should recognize the card.

Try installing kernel-2.6.18-274.18.1.el5.x86_64.rpm and kmod-igb-rhel5u7-3.0.6_k2_1.1-1.el5_7.x86_64.rpm from a mirror, such as this one.

(replace x86_64 with i386 if you're using 32-bit CentOS).

The kmod-igb package is for supporting the network card you have in that machine.

What is the model of the network card?

@RenanBirckPinheiro output of lspci |grep net is 00:19.0 Ethernet controller: intel corporation unknown device 1502 (rev 04) . I hope that adds some extra information

[Admin]

@RenanBirckPinheiro with a bit more searching it seems like this is the CPU i am using is link. And the following is given in the connectivity section Integrated Intel® 82579LM Ethernet LAN 10/100/1000 Optional Broadcom® NetXtreme® 10/100/1000 PCIe card Optional Dell Wireless 1520 PCIe (MT, DT, SFF) Optional half-mini PCIe (USFF) WLAN card (802.11n)

can you try installing a newer version of CentOS (5.8 or 6.2)? It might be supported (instead of being recognized as an "unknown device") with an updated kernel.

[Admin]

@RenanBirckPinheiro centos-5.5 is the most preferred OS for us. I need to check if there are alternatives to make the network work before giving up!

[Renan]

You could try to install the CentOS 5.8 kernel package on CentOS 5.5.

You are using an old, unsupported version of CentOS with lots of security bugs? Why on earth don`t you update?

[Nils]

Intel has very good drivers that blend into your OS. Download them, compile them and install them.

I have the same issue with my VM machine CentOS 5.8 As you said, your network card, "00:19.0 Ethernet controller: intel corporation unknown device 1502 (rev 04)" Actually this message indicates it's not supported by your OS. So i suggest you to reconfigure your network adapter with other than intel chipset, in your virtual environment check for other adapter type and replace your intel adapter type.

CentOS-5.5 is the most preferred OS for us. I am not sure but, does installing driver for that particular network card solve the problem? I am ready to take a beating before giving up!

[Greg Sadetsky]

there are no entries in any of the tabs in the system-config-network window..

[Renan]

You can try to install the CentOS 5.8 kernel (get the RPMs from a mirror).

[vyegorov]

CentOS-5.7 is last one in the CentOS-5 series. I shall install it's kernel and see if that solves the problem.

[Renan]

Indeed, my fault, I thought the latest CentOS was 5.8.

[vyegorov]

I have installed the rpm file I found in this directory. (if you search "kernel" in that page, you could easily find it.) The new kernels that show up at boot time are 2.6.18-194.el15 and 2.6.18-194.el15PAE. (neither of them work) But actually kernel I have installed is of version 2.6.18-294. Also, that rpm file was an SRPM, it if matters..
