How can I check if SSH is enabled?

I don't know my current web hosting plan is enabling SSH or not. In the case I want to disable or enable SSH connection to my server. How can I do that?

If your hosting plan is shared, it’s probably doesn’t have SSH. That the rule of thumb. If it’s VPS it will, and so will dedicated.

Connect to port 2222 with your username, password and IP provided in your welcome email, via an SSH Client.

Open a SSH connection to port 22 of your server to check if it's live. You can disable SSH, but beware that if you use it to manage your server, you won't be able to do it anymore.

If you want to disable SSH due to security concerns, you can change it's default port from 22 to any other. That should do the trick.

If you have another server you can test from you can use nmap to port scan. You can limit the scan to just port 22 using nmap -p 22 ipaddresshere or whatever other port your host has it set to use. If you don't have another server to test from you can try an online port scanning site. Quick google shows this one: https://pentest-tools.com/network-vulnerability-scanning/tcp-port-scanner-online-nmap

By default all hosting plans enable SSH, because they know you need it.
Unless others, there is a problem with the SSH configurations. The default
SSH port is 22. Also if you are behind Web application firewalls you won't
access SSH unless you use the original IP. You can use the online port scanners
to perform some checks

The best is to have a dedicated IP from your ISP then in CSF firewall you can only allow your own IP address to access SSH port.

If you have a shared plan with your host. Try connecting your account from your local shell.

using the command>

"ssh accountusername@IPofhostmachine -p 22" from your local shell.
If that doesn't work then contact your host to enable SSh access for your account.
----------------
If you have your own VPS server. Run following commands to check it:

1. netstat plan| grep :22
2.telnet localhost 22
3.telnet IPofhostmachine 22 #replace with original IP
4. service sshd status
5.ps aux | grep sshd

Please note that you cant connect to SSH of your VPS once after disabling it.
Also ensure that your the port 22 is open in your server firewall so that it can accept the external connections to that port.

From your local machine,
You can do SSH access to your VPS as root user by running the command below
> ssh root@IPofhostmachine -p 22
