You can use pkill -9 to kill process tree.
It its killed then ok otherwise use

preap 17775 
17775: exited with status 0

if you still not able to clear the process,then only way to reboot the server.
Prior to rebooting the servers,collect the following information.These information will be required to find the root cause for the issue.
1.Take the ps -ef output
2. If possible run the sun explorer and collect the data .
3. Take other necessary configuration backups like df,netstat,ifconfig commands output and reboot the server.

I'm planning to use CentOS 6.x on a handful of LAN servers. So far I've been using Slackware64 14.0 and 14.1 for the job.

I wonder what's the orthodox/recommended way of configuring and iptables firewall with CentOS. I understand there's the system-config-securitylevel-tui NCurses interface which allows defining a basic set of rules. But what about the handful of more advanced rules I have to configure?

Here's an example of an /etc/rc.d/rc.firewall script that I might use with Slackware. It contains mostly basic rules, and a couple of more advanced rules, one to limit SSH access, the other one to redirect HTTP traffic to Squid.

If I want to copy my actual firewall configuration to CentOS, what would be the recommended way? I started from a bare bones minimal CentOS 6.5 installation, so system-config-securitylevel-tui is not even installed.
Is it a good idea to try to configure /etc/sysconfig/iptables by hand? What do you suggest?

I googled to see how I might restart the network interface in CentOS. I initially tried before googling:

sudo service network restart

I noticed that only the loopback interface was restarted. To confirm this I did:

service network stop

and then did

ifconfig

and the loopback info was gone. I then found ifconfig eth0 up/down and tried those and that did what I is was looking for. Why doesn't "service network restart" restart all interfaces?

I have a server with an 17tb scsi-storage. In past, the storage has a "jfs"-filesystem. Now i want to create a "ext4"-filesystem. I have update the e2fsprogs from 1.41 to 1.42 (16tb limit >1.41).

Now I have an 17tb-storage as /dev/sda1 with ext4. I can mount this device as /home/ (/etc/fstab /dev/sda1 /home/ ext4 defaults 1 2". Now I start a e2fschk /dev/sda1 (umounted). No error-messages are in
the screen.

If I now reboot the server, the server does not started:

I think thats can be a problem with the e2fsprogs 1.42, now i reinstall the server with the default e2fsprogs 1.41 from CentOS 6.4 and create only a 16tb /dev/sda1 partition with ext4. But if i start a "e2fschk
/dev/sda1" and reboot the server, i have the same message in the boot-screen and the server does not boot.

Why the system thinks that the device still be in use? How can i change this?
