Network issue in CentOS 6.3
 
Hi Guys,

Just found an issue with CentOS 6.3. The network is getting inaccessible at times. The server has been installed with CentOS 6 and then package upgrade was performed.

=
[~]# cat /etc/redhat-release
CentOS release 6.3 (Final)
[~]#
=
=
[~]# uname -r
2.6.32-279.5.2.el6.x86_64
[~]#
=

The server is up for most of the time. But the next day when we check the server is inaccessible over network (through SSH). This happens often now.

Do you have any suggestions? Is it a CentOS 6.3 bug?

Regards
Joby

Not much info to go on here.

Look in /var/log/messages, starting when you know the connection was up
until you knew it was down. Look for messages regarding the network,
drivers or anything else that might give you a clue.

If you want more specific help, you need to ask more complete questions.
What kind of hardware do you have? What is the network card plugged
into? If it's a managed switch, look at it's logs to see if it says
anything about the given port.

Check for IP conflicts. Maybe someone else has your IP address.
