How to communicate without a passwd between 2 Unix systems where
the communicating sessions have different uid/s? (NOTE: both systems
are on OpenSSH)

e.g.


SystemA UserA SSH to SystemB UserB


Here is what I tried but failed.


As UserA in System A:



> ssh-keygen -t dsa
> cd ~/.ssh
> cat id_dsa.pub > authorized_keys2
> scp ./id_dsa.pub UserB@SystemB:.ssh/.  (when prompt for the passwd, I typed UserB's passwd)


As UserB in System B:


> cd .ssh
> cat id_dsa.pub > authorized_keys2


I tried the setup for the same user ID on both systems, it would work in the above example (i.e. SystemA UserA SSH to SystemB UserA)

Could someone tell me what am I missing?  Thank you very much!

The correct steps are:

On system A as User A

ssh-keygen -t dsa
ssh userB@systemB "mkdir .ssh;chmod 700 .ssh"
cd ~/.ssh
scp id_dsa.pub userB@systemB:.ssh/authorized_keys

Then you should be able to do:

ssh userB@systemB
