I have a question and am stuck at something. I recently created AWS EC2 Ubuntu instance with default settings. I have an Ubuntu machine locally as well and so far I managed to connect successfully to the Ubuntu instace with this command
ssh -i /var/www/my-key-pair.pem ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com
However I want to know if there is a simpler way to login to ssh without passing the private key everytime I login and add its ip to my ~/.ssh/config
so that I could login as easily as ssh ubuntu@some.ip.number
. By the way I am using AWS free tier package.
Create ~/.ssh/config
with:
Host myhost
IdentityFile /var/www/my-key-pair.pem
Use ec2-user
Hostname ec2-198-51-100-1.compute-1.amazonaws.com
And the you can login using ssh myhost
.
ssh-add -K /var/www/my-key-pair.pem
will permanently add your private key as identity file in ~/.ssh/config
.
Thus, ssh username@ip_address_of_ec2_instance
works.
To avoid typing username and IP address every time, add to .ssh/config
:
Host my-instance
HostName some.ip.address.here
User username
With this config, you can simply do ssh my-instance
to remote login.
