Why there is a network service


Dear Team,

Sorry the subject is not correct, I am running CentOS 5.5 in one of my virtual machine server, some time I see some issues with my network service, the IP is enabled and disabled. But I do not have any idea why is that? Please help me with the below log,

1. You should be on v5.10 by now ...

2. check the network cfg files as per
Code:
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: error: Missing or invalid IP4 prefix '0' =====> Time shift detected in system
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: parsing /etc/sysconfig/network-scripts/ifcfg-eth0:0 ...
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: error: Missing or invalid IP4 prefix '0'
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: parsing /etc/sysconfig/network-scripts/ifcfg-eth0:0 ...
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: error: Missing or invalid IP4 prefix '0'
Look in /etc/sysconfig/network-scripts/

Thanks for your reply,

But I do not understand what does that log means, is there any issue with the network scripts.

Hi,

again from you log:
Code:
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: parsing /etc/sysconfig/network-scripts/ifcfg-eth0:0 ...
Mar 10 08:23:41 localhost nm-system-settings: ifcfg-rh: error: Missing or invalid IP4 prefix '0'
this means you should inspect that file. If you don't know what you are looking for, try posting it here.

Evo2.

Time shift is too far for some reason. Twice in a short time.
IPv4 193.23.166.153
IPv6 fe80::20c:29ff:fe51:40bd
Might be bridged to host and host is doing this.
Odd multicast dns numbers.

The ip6 address (fe80::20c:29ff:fe51:40bd) is, I believe, just a local address.

From http://ipduh.com/ipv6/whois:
Code:
fe80::20c:29ff:fe51:40bd   ipv6
IPv6 address Type	Link Local Unicast
