Open Source Kerberos Tooling
Overview

KNC
Kharon
krb5_admin
krb5_keytab
k5ping
lnetd
prefork

A simple command line tool which tests that a KDC is performing AS_REQs, TGS_REQs, and krb524 is functioning.

For documentation, please refer to the man page (HTML, PDF).

Caveats

Currently, k5ping will only work compiled against MIT Kerberos 5 because it relies on the internal data structures to restrict the libraries to work against a single KDC at a time on a single protocol.
