Hi gurus,
I am trying to configure ssh2 for not asking passwords when logging in from a remote machine, but it is failing. I ran the command based on the oracle documentation. down below are the steps, please do let me know how to get this solved.
the steps followed
$ /usr/bin/ssh-keygen2 -t dsa

Key generated.

Passphrase :
Again :
Key is stored with NULL passphrase.
(You can ignore the following warning if you are generating hostkeys.)
This is not recommended.
Don't do this unless you know what you're doing.
If file system protections fail (someone can access the keyfile),
or if the super-user is malicious, your key can be used without
the deciphering effort.
