tcptrace is a TCP dump file analysis tool written by Shawn Ostermann
at Ohio University. It is NOT a packet capturing program. It reads
output dump files in the formats of several popular packet capturing
programs: tcpdump, snoop, etherpeek, and netm.
For each connection, it keeps track of elapsed time, bytes/segments
sent and received, retransmissions, round trip times, window
advertisements, throughput, etc. Its output format ranges from
Simple to Long to Very Detailed.
It can also produce three different types of graphs, as follows:
Time Sequence Graph
This is the format that Tim Shepard started using at MIT some
years ago. It shows segments sent and ACKs returned as a
function of time.
Instantaneous Throughput
This format shows the instantaneous (averaged over a few
segments) throughput of the connection as a function of time.
Round Trip Times
This format shows the round trip times for the ACKs as a
function of time.
The graphs produced are viewable only by Tim Shepard's wonderful xplot.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
