What protocol does Kerberos use?
UDP protocol
Kerberos is primarily a UDP protocol, although it falls back to TCP for large Kerberos tickets. This may require special configuration on firewalls to allow the UDP response from the Kerberos server (KDC). Kerberos clients need to send UDP and TCP packets on port 88 and receive replies from the Kerberos servers.
Which server is used in Kerberos?
Kerberos Servers Both the master KDC server and the slave KDC server create tickets that are used to establish authentication. The realm can also include a Kerberos application server. This server provides access to Kerberized services (such as ftp , telnet , rsh and NFS).
Does Kerberos use TCP or UDP?
The Kerberos protocol uses port 88 (UCP or TCP, both must be supported) on the KDC when used on an IP network. The spec supports using alternate ports; especially to support multiple Kerberos realms on the same server. Clients must support using TCP, but can use UDP.
