SSH Connection to Remote Server on a Non-Standard Port (Not 22):
Example: If the port is 20086, the user is user, and the IP is 192.168.0.111, the connection method is as follows:
ssh -p 20086 [email protected]
If the server user is root, you can omit the username directly:
ssh -p 20086 192.168.0.111
or
ssh 192.168.0.111 -p 20086
For scp, you should use a capital -P: as shown in the command below, which copies the file tomee.zip from the home directory on the remote host 192.168.0.111 to the home directory on the current machine:
scp -P 20086 192.168.0.111:/home/tomee.zip /home
