Need help with NIS yppasswd and others...

| Hi gents this is a newbie trying to catch up with a running system
config!
Hope you can help me, this is my issue:
I have 6 machines that can copy files by scp and run shh
comands without writting password in other machine.
The person that configured all of this doesn't longer work
with us so there's no way to know how , or why ?
I think one machine has yppasswd or shares some kind of NIS
passwd with the others , because local password where changed and the
procedures keep working.
I tried to find passwd.nis , find nis files , tried to run
yppasswd but it says there's no domain configured , or something like
that .
So ... Is there any place where I can try to find this
Network passwords so I can include a new machine in this group ??
Can any one tellme mor or less wich things I should take
in consideration to see how I works?
Excuse my English , thanks in advance, and ask as much as
you like because I can't find any answer in other groups.

Has nothing to do with NIS or yypasswd. The person created a public/private
key pair with the private key unprotected (no passphrase).

First, on the new machine as the user, generate a keypair. ssh-keygen (or ssh-keygen2)
and specify a null passphrase.
On the new machine, for the user which is the target of the ssh or
scp, add the public key from each of the other machines (~user/.ssh/id_rsa.pub)
to the ~usr/.ssh/authorized_keys file on the new machine. Additionally,
add the public key from the new machine to the authorized_keys files on
each of the other systems.
That said, this is pretty insecure. One should always have passphrases on private
keys. One can use ssh-agent to cache the private key during a session.
For further information:
man ssh
man sshd
man ssh-keygen
man ssh-agent
man ssh-add
