If your day involves ssh-ing into various servers, you know how
|
|
cumbersome is to type all that details again and again. When the number
|
|
becomes large, you tend to confuse between host names, IPs and
|
|
usernames.
|
|
|
|
But, ssh allows you to alias them into cute nicknames you prefer.
|
|
|
|
The configuration file needed to be edited is ``` ~/.ssh/config. ```
|
|
|
|
The sample configuration that should be append to this file for adding
|
|
alias _server_ to `user@example.org` is :
|
|
|
|
```
|
|
Host server
|
|
Hostname example.org
|
|
User user
|
|
```
|
|
|
|
Now all you have to do is
|
|
```
|
|
$ ssh server
|
|
```
