I don’t have a very good memory and always have problems remembering my servers names when connecting to them via SSH. I usually used this “solution”:
$ history | grep ssh
Yep… not very neat. A friend (follow him, you’ll learn lots of things!) told me I could use Control+Shift+R in the terminal and It was like “OMG! This is great!”. After pressing that key combination you can start typing a command and you’ll get matches to previous commands with that text, so all I had to do was type “ssh” and then press enter. Magic!
But today I found another way that involved using the
~/.ssh/config file. The first step is to create this file in the correct place and, most important, with the correct permissions:
$ touch ~/.ssh/config
$ chmod 600 ~/.ssh/config
Now lets suppose we usually connect to a server called
vps1.hostingsolution.com with a user named
myuser. We can add this to
And here comes the cool part: now we can connect to this server with that user name by just typing this:
$ ssh vps1
That’s it. And of course you can add more and more configurations to it:
And if we also have enabled the connection using public/private keys we don’t even have to write a password.
This file is very heplful for other things too. For example you can make speed up SSH if you configure
ControlMaster because it enables the sharing of multiple sessions over a single network connection.
If you get this error while connecting after configuring this it’s very likely because the
ControlPath route does not exists or is write protected:
muxserver_listen bind(): No such file or directory
