ssh

Hi all,

Quite an easy one. I have 2 servers and would like to have a public key for each of them (same user though). So on my box I ran as the user;

ssh-keygen -t dsa

copied the public key over to the server and put into authorized_keys, all works fine.

How do I manage 2 keys on the local machine (not the server)? I understand I could make a new key, copy the .pub over to the 2nd server and create a new authorized_keys file, but how do I store multiple keys on my personal machine?

So, quite simply really but I'm missing the plot somewhere

Thanks.

I'm not quite sure I understand what you are trying to do, so bear with me.

You have 2 servers and a workstation?

If the above is true, is there a specific reason you want a unique key for each server?

You can use ~/.ssh/config to specify different options for different hosts:

Code:

#Host directive makes following directives only apply to that host, it
#checks the based on the name given on the command line, can use * and
#? wildcards
Host host1
IdentityFile ~/.ssh/id_dsa1

Host host2
IdentityFile ~/.ssh/id_dsa2

man ssh_config for more details

I was just wondering if it were possible. I should know better than to delve into the man pages

Thanks for your input guys, I'll take a look at it now.
