I have just installed two machines with FreeBSD 4.1.1. I'm trying to
set up SSH for my account (not root). When I installed FreeBSD I set
the security level to "medium" so I could telnet in while I figure
things out. It appears that the sshd for the "medium" setting uses
SSH1. Does the "high" security setting use SSH2? Should I care?
So far I have done the following to allow ssh connections from host A
to host B.
* I ran 'ssh-keygen' on host A. I accepted the default file names. I
entered a pass phrase when prompted.
What's the purpose of the passphrase? Do I need one?
* I copied the contents of A:~/.ssh/identity.pub into
B:~/.ssh/authorized_keys.
The first time I ran 'ssh B' on host A I got the following:
The authenticity of host 'B' can't be established.
RSA key fingerprint is xx:xx:xx:....
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'B' (RSA) to the list of known hosts.
Enter passphrase for RSA key 'tayers@A.foo.net':
and then I was logged into B. Is the "The authenticity of host 'B'"
message of any concern? Does it always say that when you connect to a
machine for the first time? Is there another step I should do to avoid
this warning?
Then I disconnect from B and connect again: 'ssh B'. It works without
the "authenticity" warning, but it prompts for the passphrase
again. Blech. ;-p Is there a way to set this up so I don't have to
type the passphrase in all the time? Having to type the passphrase
makes doing 'ssh B <command>' from a script kind of troublesome.
Thanks a lot for your help and
Hope you have a very nice day, :-)
