Mini HOWTOS.

I install openssh server and sort out setting up the right ssh keys for the user so I can login to other machines locally without a password. This is a security risk! I want to use Xwindows programs installed and run on one machine while actually running on another, hence the ForwardX11 bit.

Follow up:

To allow a user from one machine to login to another another machine, you need to update the authorized user file to include the details from the guests id_rsa.pub. It is the same as saying if my friend uses their front door key in my lock it will work.

Now copy the public key from the client machine to the authorized keys of the client

And then do the same thing the other way around.

Now test that you can actually ssh to/from linux60 without a password. No need to reboot or logout. If you cannot you did it wrong.

This is a security risk, only do this if you accept this and are willing to take the chance. Remember it was your choice to do this not mine!
