where to see public key for a server where to see public key Debian where to see .pub Debian id_rsa.pub Debian

To allow ServerA to SSH to ServerB without password, please try the following:

ssh-keygen -t rsa

Note: User here is root

This generates two files id_rsa.pub and id_rsa

Now, this needs to be copied to the authorized_keys file on ServerB

scp id_rsa.pub ServerB:~/.ssh/ServerA_rsa.pub

(If you already have passwords turned off )

cat ServerA_rsa.pub >> authorized_keys

Thats it. Test if you are able to do a ssh from ServerA without a password:

ssh serverB uname -a

This will run the command “uname -a” on ServerB and returns the result on ServerA.
