Appendix A. TCP, UDP Ports, and ICMP Message Types

Appendix A. TCP, UDP Ports, and ICMP Message Types

I list useful TCP, UDP ports, and ICMP message types in this appendix. There exist a small number of remotely exploitable network services I don't cover in the book, but list here?for example, the Solaris dtspcd service on port 6112 and the X font server on port 7100.

A comprehensive list of registered TCP and UDP services may be found at http://www.iana.org/assignments/port-numbers. The nmap-services list of ports provided with nmap is also a good reference, particularly for backdoors and other unregistered services.
