Adding a banner to your Dedicated Server is extremely easy to do. It is comprised of 2 steps.

1.) Edit your sshd_config file located at /etc/ssh/sshd_config and add the folowing line:

Banner /etc/banner

2.) Now you need to create this file. Using your favorite editor, just create the new file and put whatever you would like your users to see when they attempt to login to your Dedicated Server.

Here is an example:

This computer system is for authorized users only. All activity is logged and regulary checked by systems personal. Individuals using this system without authority or in excess of their authority are subject to having all their services revoked. Any illegal services run by user or attempts to take down this server or its services will be reported to local law enforcement, and said user will be punished to the full extent of the law. Anyone using this system consents to these terms.

For security reason its always better tio disable IPV6 on Linus server, as IPV6 traffic is not filter by server firewall. Refer following steps to disable IPV6.

Login in to server as root user and open networking file.

root@server[~]#pico /etc/sysconfig/network

Add following two lines in the end of network file.

NETWORKING_IPV6=no
IPV6INIT=no

save network file  and restart network service or simply reboot server to implement changes

Its very common issue, every new techie not sure about server bit at that time simply run following command to get bit information.

getconf LONG_BIT

We can mount the remote directory on the Linux Server by using the following three simple commands only.

Login in to the server as a root user and run the commands one by one and make sure that you are using your own remote server ip instead of our test server ip198.168.0.2

yum install fuse-sshfs

The above command will install the fuse-sshfs

Create the mount directory where you want to mount the remote directory.

mkdir /mnt/remotemount

Now mount the remote directory make sure that you are using the correct remote directory server ip and root password

sshfs root@192.168.1.2:/the_physical_path_which_you_are_mounting  /mnt/remotemount

Now check the mount point

mount

If you want to remove the mount point then use the following command

umount /mnt/remotemount

If above command shows the error “mount point busy” the use the following command

umount -l /mnt/remotemount

Most of the time on cPanel dedicated server we add nameservers from WHM but some time we are not able to access WHM. In that case we can add nameservers from shell by using root login details.

Login in to server as root user and run following commands.

root@server[~]#/scripts/adddns –domain ns1.your_domain.com –ip=111.222.222.1

root@server[~]#/scripts/adddns –domain ns2.your_domain.com –ip=111.222.222.2

You can use your domain name instead of your_domain.com in above command with the respective ips which you want to use for your nameservers.

root@server[~]#service named restart
or
root@server[~]#/etc/init.d/named restart
