[cobalt-users] RE : RSYNC - Automation. with out password

["MAHESH PATIL" <mahesh_patil_99@xxxxxxxxxxxx>]

Thanks to all for your help.
I got it. Now RSYNC is working with out prompting for password. 

I wanted to use The SSH as transport and hence it was ssh which was aksing for the password.

But with your guidance I could find out the way to do it.

I did it in the following method.

THIS WORKS
 
If you want to use ssh non-interactively, don't try and do it with stored passwords; instead, use keys. For most any ssh, I believe you should be able to go something like this, where $dst is the destination host you want to connect to. Run this as the originating
user on the originating host, and if the dst user is not the same as the originating user, set dst to dstuser@dsthost. 

$  ssh-keygen 

# hit enter three times, to choose the default
# target of ~/.ssh/identity for the key, and enter
# an empty passphrase twice
$ ssh $dst mkdir -p .ssh
$ ssh $dst chmod 700 .ssh
$ scp .ssh/identity.pub $dst:.ssh/authorized_keys
$ ssh $dst chmod 600 .ssh/authorized_keys 

At this point you should be able to ssh $dst with no password requested. 

(This metod did not work for me. So I followed the method below and it worked perfectly. Assume that this mehod worked in old version of SSH.)

If you're using the latest version of openssh, and you wish to avoid violating RSA Data Security's patent on RSA public key encryption (valid for another 3 months from today, to the day) then you can use 

$ ssh-keygen -d 

to generate "id_dsa" and "id_dsa.pub" rather than "identity"; then
$ copy id_dsa.pub to $dst/.ssh/authorized_keys2.Q 

Thats all.

I Love this list.
