Abstract
This paper describes the file format used by "snoop", a packet
monitoring and capture program developed by Sun. This paper is
provided so that people can write compatible programs to generate and
interpret snoop packet capture files.
1. Introduction
The availability of tools to capture, display and interpret packets
traversing a network has proven extremely useful in debugging
networking problems. The ability to capture packets and store them
for later analysis allows one to de-couple the tasks of collecting
information about a network problem and analysing that information.
The "snoop" program, developed by Sun, has the ability to capture
packets and store them in a file, and can interpret the packets
stored in capture files. This RFC describes the file format that the
snoop program uses to store captured packets. This paper was written
so that others may write programs to interpret the capture files
generated by snoop, or create capture files that can be interpreted
by snoop.
