libpam-opie 0.21-8build1 (hppa binary) in ubuntu gutsy

 Use OPIE one time passwords for PAM authentication. A one time password
 is useful to avoid having your password sniffed and reused if you log
 in via an unencrypted channel or from a compromised system. The PAM
 module enables OPIE for programs such as SSH which use PAM for
 authentication.
