The default ports used by Kerberos are port 88 for the KDC1and port 749 for the admin server. You can, however, choose to run on other ports, as long as they are specified in each host's /etc/servicesand krb5.conffiles, and the kdc.conffile on each KDC. For a more thorough treatment of port numbers used by the Kerberos V5 programs, refer to the
