We saw that we can ssh
into our vagrant virtual machine in the post Add SSH Public Key to Vagrant:
$ ssh -i ~/.ssh/id_rsa.pub -p 2222 vagrant@localhost
However it is too long to type, right? And if you ssh into a server you should remember the IP, like 173.108.251.102
. There should be an easy way to do that since we all are lazy developers (?).
The ssh program on a host receives it's configuration from either the
-
cli
(as we've seen above), -
/etc/ssh/ssh_config
file for global-scope, -
~/.ssh/config
file for user-scope.
These files are formatted like below:
For our local vagrant machine:
Host vagrantlocal
HostName localhost
Port 2222
User vagrant
IdentityFile ~/.ssh/id_rsa.pub
PasswordAuthentication no
For a remote server:
Host myremoteserver
HostName 173.108.251.102
User user
IdentityFile ~/.ssh/id_rsa.pub
PasswordAuthentication no
And then you can access them via ssh
:
# vagrant virtual machine
$ ssh vagrantlocal
# remove server
$ ssh myremoteserver
You can see more configuration file options at Configuration Options.
All done!
