I am using Ubuntu 16.04 on an RPi 3 model B which I want to access using SSH

Using the long command:

$ ssh username@hostname

OR

$ ssh username@pi.ip.add.ress

I am able to successfully ssh into my RPi. But after creating the alias in ~/.ssh/config like:

Host myshortuser

    User username

    Hostname pi.ip.add.ress

and then try the command:

$ ssh myshortuser

I get the error:

ssh: Could not resolve hostname myshortuser: Temporary failure in name resolution

  @Christopher: why? That's totally defeats the purpose of the Host stanza in the ssh_config. The whole point is to assign a name independent of the host name.

  @Christopher: every entry on the Host line can be a nickname (or alias, as Hassaan put it), as long as there is a HostName stanza. Additional rules apply. I've used this for example to fake old non-existent domain names in a CVSROOT when the server got moved.

  @Christopher: Editing your /etc/hosts requires privileges you may not have as ordinary user. With your advice you are subverting one of the really cool features the OpenSSH client and ssh_config(5) have to offer. It's true that your method will work, but only if the HostName stanza is removed at the same time from the SSH config file.

  Run ssh -vv myshortuser id 2>&1 > sshoutput.log. Then look in sshoutput.log for any errors. Your system doesn't seem to be reading the ~/.ssh/config file. That may be due to permissions, or due to a system wide restriction on reading user files.

please make sure the hostname is unique in your network.

sudo nano /etc/hosts --> will show the list of the hostnames.
Please change the hostname at 127.0.1.1

to make the changes effected, please run

sudo /etc/init.d/hostname.sh

sudo reboot

  The hostname created is unique; there is no other system in my network with the same hostname.
