Who can solve the problem of Determining IP information for eth0?\n\nOur robot (Red Hat Linux 6.2) was experiencing a problem as follows: first, the IP address was found after log in. The second time when the robot was rebooted to confirm the IP address, response only shows 127.0.0.1. \n \nActually, the error lies mainly in \n"Bringing up interface lo [ OK ]\n\nBringing up interface eth0 Determining IP information for eth0...Operation failed.\nfailed.\n[FAILED]"\n \nWe have tried different network cables, network pins and checked the plug is well enough.

1. Make sure the ethernet card is recognized and driver module is loaded on startup. can u paste the result of the following two commands:
lspci --- List all pci device
lsmod --- List loaded modules

2. If your ethernet card is not well configured, configure again using "netconfig". If you have a static IP, just give all the informations, if using DHCP, then choose dhcp.

3. After configuration, restart the networking

/etc/init.d/network restart


Good luck

Because the driver modules already loaded, u can try to bring up the network manually by run

#/etc/init.d/network restart

If any error, post here.

I changed the hostname temperorily to other rather than prod1 and used netconfig to set an ip for the robot. Then network works.

It seems that the hostname of the robot is colliding with other pc at NUS.

So I change the content of HOSTNAME, hosts, host.conf and expect the hostname will be changed permainently. But after reboot, the hostname changed back to prod1 as well as the content of HOSTNAME.


Could you please advice on how to work out this problem? Lots of Thanks.


BTW, maybe #/etc/init.d/network restart should be #/etc/networks restart

If you want to change the hostname , do this:

1. Change it in /etc/sysconfig/network.

2. Change it in /etc/hosts.

3. Issue the command "hostname newhostname".

Now it's done and will also be remembered at next boot.

Nice to know you, a Linux expert(at least in my eyes)
