On each of the sun machines we need a user 'abc' with the ssh authorized_hosts entries of xyz and also sudo rights
the ssh keys a dedicated to the one program prg.sh so that only this program can be run by the user.
so wat i have to do inorder to achieve the above task . i mean where i have to place the corresponding authorized_keys and hosts files and also how can i set ssh_keys to execute only one particular program.
Place the authorized_keys file in the users home directory under ~/.ssh/
The authorized_keys file should contain the user's PUBLIC keys
/home/abc/.ssh/authorized_keys
Make sure the file is readable only by the owner 'abc' and the .ssh directory is readable only by the owner.
chown -R abc /home/abc/.ssh
chmod 500 /home/abc/.ssh
chmod 400 /home/abc/authorized_keys
If the permissions are incorrect sshd will log the error to STDLOG (/var/adm/messages)
Use RBAC instead of sudo. There is plenty of documentation on how to set this up in http://docs.sun.com/app/docs/doc/817-0365/6mg5vpmbd#hic
