Tweak to ssh quickly any server

To ssh to server, I used to type ssh --flags, the command line too long and replication. Here is a solution reduce the pain.

Go to file ~/.ssh/config, and add the following configuration. If the file is not exist, you can make a new one.

Host server-dev1
Hostname  xxx.xxx.xxx.xxx
Port 1022
User nguyenvinhlinh

Host server-dev2
Hostname  xxx.xxx.xxx.xxx
Port 1023
User nguyenhoangson

Right after that, you can use ssh with server alias name.

$ ssh server-dev1
$ ssh server-dev2
