Organize telnet and ssh connections in terminal

There are graphical applications like SecureCRT o Gnome ConnectionManager to organize our remote connections, but if like me, you prefer to do everything possible in the terminal, you will like this.

Many of us connect to a large number of computers remotely. Imagine that we have a web server in 192.168.0.100. The username with which we access is foo and also to the ssh service we have changed the port for 2244.

Whenever we want to connect we should write:

$ ssh foo@192.168.0.100 -p 2244

If we have a lot of machines to access remotely… This is not productive at all.

To better handle ssh connections from the terminal, we must create the file ~ / .ssh / config. In this file we will use the following structure:

Host webserver Hostname 192.168.0.100 User foo Port 2244

As in the example, we would fill the file with all the ssh connections that we usually make.

Now from the terminal, write ssh web server will be the same as ssh foo@192.168.0.100 -p 2244.

For connections telnet, we would have to edit our .bashrc and add for example:

r1-bcn () {telnet 10.0.0.1}

After editing this file we must do source .bashrc so that the new changes that we have made are loaded without restarting.

If we write r1-bcn in the terminal, we will connect to our telnet session.

In both cases, when tabulating it autocompletes me or shows me all the available options. It may not work in some distribution first, but looking for a bit is very easy to solve.

I don't know if there are other methods to have all your remote accesses organized, if someone knows any other way, I would love to know it:).
