VOS3000 Server SSH port Change Easy Commands!

Hello,

Due to security issue many people need to change ssh default ports. Non only for voip hacking issues, there are lots of spammer scan linux server ssh ports, so its good if you keep it changed to different ports. So i am sharing how you can change it easily.

I am giving command serially:

# vi /etc/ssh/sshd_config

# nano /etc/ssh/sshd_config

Some people like default editor “vi” is by default work for all linux. Some people like “nano” editor, so both command i shared earlier. Now you will see below image at your vos3000 server

Here you can see default vos3000 server port is 22. You just simply write “port” and space then your desired ports. In image you can see we used ports 34627. Then save it by using default commands of your editor. For “vi” command to write anything you need to press “i” then you can change anything and then “Esc” to complete and save command is :q!” and enter.

For nano simply you can change and after change you can save by “cntrl+x” and then “y” and enter.

After that for Centos 5.x and Centos 6.x server you need to use below command for restart the ssh service.

# service sshd restart

And for Centos 7.x server command is:

# systemctl restart ssh

VOS3000 2.1.1.5, 2.1.2.0, 2.1.2.4 mostly works in centos 5.x . VOS3000 2.1.2.4 can works in centos 6.x also but emp will not work properly and voice issue will be there. Newer VOS3000 2.1.4.0 or VOS3000 2.1.6.0 works in centos 6.x newer versions also. For compatibility of VOS3000 installation in linux server and which centos required for which version you can see my other post where i mentioned kernel version where emp matched easily. Also you can downgrade or upgrade kernel easily. Will post later about this. Keep tuned in our blog for it.

We also recommend ssh blocking by ip authentication based firewall. So it will be more secured for vos3000 server hacking which is common now a days.
