[wplug] sshd config -- no password?

[Embery, Nathan]

Here's the notes I jotted down the last time I did this on FreeBSD and
Solaris
They may not be exact, but close enough to get you started.
Nate

Log into your freebsd box 
run #ssh-keygen -t dsa 
 
This will create your id_dsa and id_dsa.pub files in ~/.ssh/ 
 
Now copy your id_dsa.pub to the target machine 
 
scp ~/.ssh/id_dsa.pub ip_or_hostname:/home/nate/xfilename 
 
then log in to that box 
 
ssh ip_or_hostname 
 
enter your password for the last time ;-) 
 
copy the source machines public key into your authorized_keys2 file (you may
need to touch it) 
 
touch ~/.ssh/authorized_keys2 
cat xfilename >> authorized_keys2 
 
exit your shell, returning to the source machine 
 
test with ssh nate at ip_or_hostname 
 
repeat this process using the target machine as the source machine

Subject: [wplug] sshd config -- no password?


I'm looking for a way to allow ssh connections from certain machines
without requiring passwords.  I have a script that connects to my machine
and checks if a certain process is running.  I want this to occur
automatically, without having to enter a pwd each time it connects.  Is
there a way I can specify to sshd a list of hosts that don't have to
authenticate (while still requiring others to)?  I'm guessing this has to
do with specifying host keys to sshd_config -- but I don't even know where
to start.

Thanks,

Ryan
