Do you need a port to Ping to SSH?
Ping uses the icmp protocol, which doesn’t require a port. ssh needs port 22 (by default) to be open on the machine to which you’re attempting to connect, and an ssh daemon running. To check the port is open on ‘the first’ machine, 192.168.0.1 :
Is it OK to have a ping connection?

Why is my laptop pinging my SSH connection?
If the original poster is able to SSH to the device from his laptop then this demonstrates that SSH is enabled and seems correctly configured (which rules out one of the most common problems).

Unfortunately, terminal freezes in 10 – 15 minutes after I connected with the remote server from home. There’s no error/timeout report on the console but the cursor cannot move any more.
How does the SSH daemon keep the connection alive?
The ssh daemon (sshd), which runs server-side, closes the connection from the server-side if the client goes silent (i.e., does not send information). To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while.
How to find alive hosts with Bash Ping?
(Disclaimer- I know this can be done more easily with nmap, but its supposed to be practice for bash shell scripting). $ scriptname 192.168.42 18 23 Checking: 192.168.42.18 19 20 21 22 23 Live hosts: 192.168.42.21 192.168.42.22 There were: 5 alive hosts 1 not alive hosts found through the use of ‘ping’. Above is what I want the output to look like.
