Notes on SSH Configuration on Linux
If you want to use ssh
to connect to another server, using an authorized key instead of a password:
In your home directory:
chmod 700 .ssh
cd .ssh
chmod 600 authorized_keys
ssh-keygen -t rsa -b 2048
For a first-time connection, I tend to do it manually at the command line to get the fingerprint stored:
server1$ ssh server2
(& vice versa as needed)
Then place the contents of the other host’s pub.key
into this authorized_keys
file:
ssh-copyid who@where
Or just copy the string manually.
