What would you do  ?

 What would you do when there is no telnet client enabled but you want to test a port, most of the linux clients are installed with curl, in that case we can use curl to achieve the same.

curl -v telnet://x.x.x.x:22

* About to connect() to x.x.x.x port 22 (#0)

* Trying x.x.x.x...

* Connected to x.x.x.x (x.x.x.x) port 22 (#0)
