Author of this application is [Tom Poindexter] and [Keith Vetter]. sockspy [http://www.neosoft.com/tcl/ftparchive/sorted/net/sockspy-1.0] "watch[[es]] the conversation of a Tcp client and server", according to its quite readable README [http://www.neosoft.com/tcl/ftparchive/sorted/net/sockspy-1.0/1.0/sockspy-1.0.README]. Although "not a replacement for heavy duty tools such as 'tcpdump' and other passive packet sniffers" (Ethereal [http://www.ethereal.com/], ...), it's easy to install, configure, and launch, and pleasingly convenient for "debugging Tcp client/server programs, examining protocols and diagnosing network problems". sockspy is nearly indispensable for any network programmer or network administrator, quite apart from any interest they might have in Tcl. [[Compare to tcpdump, ...]] ---- Version 2.0 of sockspy is available on sourceforge at [http://prdownloads.sourceforge.net/sockspy/sockspy.tcl]. [http://sockspy.sourceforge.net/sockspy.html] documents sockspy. Among the new features are: * reorganized GUI to use one pane and different colors to indicate client, server and meta data * can be run as a command-line (tcl not tk) application. Before 2.0, sockspy was inherently Tk * you can stop, start and change the socket forwarding configuration from within the application Keith has also updated [http://sockspy.sourceforge.net/sockspy.html] Tom's version 1.0 tutorial. ---- [Sebastian Wangnick] has an interesting complement to sockspy he calls [ipc]. [[Also explain relations to sniffers--tcpdump, ethereal, ..., and [pktsrc] ]] ---- [CL] plans a couple of articles (late?) in 2002 on sockspy applications. ---- [Category Application]
