krb5-rsh-server 1:1.0.1-1 (i386 binary) in ubuntu natty

 Kerberos is a system for authenticating users and services on a network.
 Kerberos is a trusted third-party service. That means that there is a
 third party (the Kerberos server) that is trusted by all the entities on
 the network (users and services, usually called "principals").
 .
 This is the MIT reference implementation of Kerberos V5.
 .
 This package contains replacements for rshd and rlogind that use Kerberos
 for authentication.
