[unfortunately too late for 0.8.16...] Hethereal provides an HTML interface to Ethereal. It uses a lot of Javascript and was successfully testet against Netscape-4.76 (Linux) and IE-5.5. Unfortunately Konqueror doesn't work and Mozilla (Linux) has big trouble with frames. We also use the cgihtml library, a C-API to CGI-environment. See below. You can see Hethereal in action on http://www.abmlinux.org/cgi-bin/hethereal.cgi. This is part of our (3 students) diploma work and is intented to build a protocol-analysator based on an Embedded-PC running Linux, so the only interface shall be the Apache (mod_ssl) WebServer. I would never recommend running Hethereal (we thought about naming it heathereal....) on Servers connected to the outside world. But it looks quite nice so give it a try anyway ;-) I have compiled the binary referenced above with capturing disabled. The (only available) capture-file "dump" contains a new, not yet released dissector for BACnet (Building Automation and Control networks). See http://www.abmlinux.org for details about our whole work. The dissector will be mailed to this list soon. new files: hethereal.c (attached) modified files: print.c (diff attached) new libraries: cgihtml (see notes below) additional files: hethereal_addons.tgz (attached) Images and two HTML-files To do for compiling / releasing: fix header of hethereal.c to work with CVS (sorry, new to that) expand Makefile.am, Makefile.in and Makefile.nmake to work with hethereal and cgihtml. Installation: The binary must be copied to a valid CGI-Path, like /usr/lib/cgi-bin/hethereal.cgi. Make it SUID root to be able to capture packets. Extract hethereal_addons.tgz to DocumentRoot. This creates a subdir /hethereal. Changing the sources: All parameters for hethereal's behavior are set in function main() through struct html_cfg. You can even change all color-defs there. Have a closer look to the path-variables base_path and cf_path. htmlcgi: We are using version 1.61 from Eugene Eric Kim, eekim@xxxxxxxxx. It can be downloaded from http://www.eekim.com/software/cgihtml/index.html. This might be the point where Hethereal gets incompatible to Windows...
