Francesco Stablum


Artyom Khafizov

Bugfixes and memory leak fixes, added RESET and EXPIRED status detection, added a new way to write the stream to files, using directories.

Federico Castaneda

Added basic UDP support

Buck Huppmann

wrote the RESET status detection

Saumil Shah

has helped me improving tcpick and making it useful to decode application-level data (i.e. http).

Gianluigi Spagnuolo, kirash

has tested tcpick under many *BSD systems, helping me to make tcpick more compatible on other systems. He found also the pcap_next bug and a bug on the inet_ntoa return ointer. Kirash is currently helping me with several patches and increasing the tcpick portability, which is really very important.

Penelope Fudd

Added a patch that allows to process with tcpick a tcpdump output file instead of a live connection, in that way:

     % tcpdump -n -s 1600 -w /tmp/foo.tcpdump
     % tcpick -r /tmp/foo.tcpdump


helped me to improve the performance of tcpick suggesting me a method of session recognization with hash generated by addresses and ports and a "chained" tracker of structures instead of a block of addresses to structures (i.e. conn_ptr->next_conn).

Sebastian Prause

added support for DLT_PPP_ETHER datalink type (including pppoe for NetBSD systems).


wrote a nice dprintf function for debugging purposes :)


Spent a lot of time seeking for a bug I couldn't resolve on a free().


bug found at pcap_next, that returns NULL on some systems suggested me to change pcap #include directive, because on trustix (and perhaps other linux systems) libpcap are located in a different place (pcap/pcap.h).

Ardoino Paolo

Suggested me to control memory allocated addresses

Robert Scheck

suggested me to improve the Makefile with variables.

Alberto 'JCN-9000' Varesio:

found that AIX doesn't have getopt_long and getopt.h

Davide Benini

corrected bug in calling S_calloc with only one argument

Maurizio Lemmo `Tannoiser'

Source RPM

Paul Drain mantains tcpick as a recompilable source RPM:


Mantained by Dag Wieers, with a lot of platforms available:

Lou Afonso has compiled version 0.1.20

Testers (read PLATFORMS.old file)

nextime has spent time compiling tcpick on an impressing number of unix/gnu platforms helping me understanding tcpick [in]compatibilities

AdHe5, Alt[O]s, hannibal, Kaioh, Alberto Panu, Maurizio Lemmo `Tannoiser', Alberto 'JCN-9000' Varesio, gap, Kirillov

thanks to these people because they spent time testing tcpick on their unix and linux distros sending me the report, that I used to complete `PLATFORMS' file.


Thanks to all people that are using tcpick and are sending me description of problems encountered and to all people here not mentioned that contributed to this software in many ways.

Thanks to that hosts tcpick, available here:

Thanks to, that is currently hosting tcpick packages at this url:

Thanks to all the mantainers of libpcap (, that indirectly contributed to the development of tcpick :)

Thanks to webmasters, that have added tcpick in their directory.
