[SOLVED] network could not start

windstory · 06-02-2009, 03:38 AM

My box is centos 5.2 x86 on vmware.
Suddenly after restarting centos could not start connect internet.
So I checked "ifconfig" as follows:

Quote:

[root:localhost:~]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:2661 errors:0 dropped:0 overruns:0 frame:0
TX packets:2661 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:3765296 (3.5 MiB) TX bytes:3765296 (3.5 MiB)

How can I solve this problem?

Any helpful comment would be appreciated.

lets see the contents of /etc/sysconfig/network-scripts/ifcfg-*

"the contents of /etc/sysconfig/network-scripts/ifcfg-lo" is

Quote:

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

for starters, you need to have a config file for eth0. This should get you the basics and let the system bring up the interface:

as root...

Code:

sed "s/=lo$/=eth0/; s/=127.0.0.1/=192.168.0.1/; s/=255.0.0.0/=255.255.255.0/; s/=127.0.0.0/=192.168.0.0/; s/=127.255.255.255/=192.168.0.255/; s/=loopback/=eth0/" /etc/sysconfig/network-scripts/ifcfg-lo > /etc/sysconfig/network-scripts/ifcfg-eth0

Now you'll have to figure out what ip addressing VMware expects on that interface...
