history
Project history and usage
Yconalyzer is a low-overhead libpcap-based TCP connection analyzer. It captures or reads pcap data for a selected TCP port and summarizes connection duration, retry behavior, volume, and throughput.
Project history
Yconalyzer was published on SourceForge as TCP Traffic Analyzer by Subbu Subramaniam. Its file feed shows early public tarballs in April 2010, followed by 1.0.x source archives and changelogs through June 2010.
The project manual explains the core design: capture only TCP control packets with SYN, FIN, or RST set, then use those comparatively small packet streams to infer connection-level performance. That made it a specialized monitoring tool rather than a full packet dissector.
Adoption history
Yconalyzer appears to have had modest adoption. It is documented on SourceForge, has a FreeBSD ports entry, and is packaged by Homebrew, but the available source material points to a small utility with a narrow operator audience rather than a large active ecosystem.
Its adoption niche is server-side traffic diagnosis where tcpdump-compatible pcap files are already part of the workflow and an operator wants connection distributions without running a heavier analyzer.
How it is used
The manual describes three modes: capture mode with `-w`, analyze mode with `-r`, and live traffic analysis. The `-p` port option is mandatory, and users can add ordinary tcpdump/BPF filters to narrow the capture.
Typical examples include capturing port 80 or port 25 control packets, analyzing tcpdump-created pcap files, bucketing connections by duration or byte volume, and piping raw output through shell scripts for cron-based monitoring or alerts.
Why package nerds care
Yconalyzer matters as an example of a tiny operations tool whose packaging value is preservation. The upstream is quiet, but package managers keep a buildable command around for people who still want this exact pcap-to-connection-summary behavior.
It also demonstrates a classic Unix packaging pattern: a small C network utility, libpcap as the real platform interface, text output for scripts, and compatibility with tcpdump files.
