There are currently four mailing lists that pertain to tcptrace. The two intended for normal users are the "tcptrace" and "tcptrace-announce" mailing lists. tcptrace-announce is a very low traffic list, which probably only sees one or two messages a year. Everyone who uses tcptrace is encouraged to subscribe to this list, as it is used to spread the word when significant new versions of the program come out and major bugs are found and fixed. You can subscribe to the tcptrace-announce list by sending an email to majordomo@tcptrace.org that contains the text "subscribe tcptrace-announce". Should you wish to be removed from the list, all you need to do is send an email to majordomo@tcptrace.org with the text "unsubscribe tcptrace-announce" in the body. No one except the list owner at tcptrace.org may post to this list. The list that serves as a forum for most tcptrace related discussion can be subscribed to by sending email to majordomo@tcptrace.org with the text "subscribe tcptrace" contained in the body. Unsubscribing is as easy as sending majordomo@tcptrace.org a message containing "unsubscribe tcptrace" in the body. Posting to this list is restricted to list members only, due to problems with spam and such. Traffic on this list is rather light as well, mostly occurring in short spurts when someone has a question or shares some tcptrace related software they've written with the community. You may post to the list by sending your message to tcptrace@tcptrace.org, if you are subscribed to the list. Before posting questions to this list, please consider that there are about 400 members, so if your question is just something basic about compiling the program or reading input files perhaps the tcptrace- maintainers list discussed in the next paragraph is a better venue to ask it. Problems with subscribing/unsubscribing should be sent to owner-tcptrace@tcptrace.org There are also two lists "tcptrace-bugs" and "tcptrace-maintainers" which are used for notifying us that there is a problem. If you find what you think is a bug in the software, please send a message to tcptrace-bugs@tcptrace.org. This list has all the active tcptrace developers on it, so usually someone can get on it and write a bugfix fairly quickly, but it's also quite nice when people send in their own bugfix code. tcptrace-maintainers@tcptrace.org is the list which you can use to contact all the people responsible for keeping up the tcptrace mailing lists, website, and CVS tree. Problems compiling tcptrace and questions about how to use the software or interpreting the output it produces should be addressed to the tcptrace-maintainers list. You will generally receive an answer fairly promptly. tcptrace was written by Shawn Ostermann at Ohio University, who can be reached at ostermann@cs.ohiou.edu to ask questions about the licensing of the software. HTML archives of the "tcptrace" and "tcptrace-bugs" lists can be found on the tcptrace website at http://www.tcptrace.org.
