Ethereal-dev: [Ethereal-dev] new add-on: Hethereal

Note: This archive is from the project's previous web site, ethereal.com. This list is no longer active.

[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, [email protected] It can be 
downloaded from http://www.eekim.com/software/cgihtml/index.html. This might 
be the point where Hethereal gets incompatible to Windows...
