Please see the FAQ item "Are there any
tools available for debugging Winsock programs?" for more information
on sniffers and shims.
Ratings: Packages are rated on a simple 5-point system. Features
and usablility are rated on the following scale:
 |
5 points |
This is a wonderful product and you should waste no
time getting it, if price permits. |
| |
4 points |
Nearly perfect. Its features are competitive with
others in its price class. |
| |
3 points |
Adequate. This product may be mildly buggy, but
it's tolerable. It does what the manual says it will,
and it's reasonably usable. |
| |
2 points |
Yick! This product is buggy, weak, and/or hard to
use. Use only if there's no other choice. |
| |
1 point |
This product is unusable. Stay away. |
I've ranked these products from a network developer's perspective.
Many of these products are actually targetted towards network
administrators, so their focus is a bit off of what the developer needs.
So, "alert via pager" features won't help a product's ratings, but
available source code and a protocol dissector API will.
Price also matters. A program with features comparable to higher-priced
programs gets one extra point. So, a cheap program given 3 points on its
own merits would get an extra point if its features were comparable to
a more expensive product.
Ratings do not take the platform into account. I do not know what
systems you are comfortable with, or what you have available to you for
debugging machines. So, I leave it to you to weight my ratings against
your platform preferences. (Any apparent bias against the Unix and DOS
text UI programs is due to inherent usability issues.)
If the "Date tried" field is "Long, long ago", the review is probably
sadly outdated. I don't have any information on when I last tried the
product in question.
Network Sniffers:
| Package: |
Wireshark |
| Author: |
Many people! |
| Platform(s): |
Unix, Win32 |
| User interface: |
GUI |
| Licensing: |
GPL |
| Commentary: |
Wireshark (née Ethereal) is probably the most popular sniffer
in the world now, because it is both open source and usable. It has
all the base features you'd expect in a sniffer. Although it lacks
some of the features of the commercial sniffers aimed at network
management folk, it is strong in other ways. For example it's a
single click to turn a series of raw packets into a view showing
the TCP conversation in logical order.
Wireshark understands a great many protocols, allows for user-written
protocol dissectors, can read capture files written by many other
sniffer programs, and comes with source code. It's also portable
to virtually all Unixen and to Windows. The latter is not an
afterthought: Windows installers are built for every release, soon
after the initial source code release.
A truly killer feature is that you can use it to remotely debug
network problems: you can dial or ssh into to any random Unix box
at a remote customer site, upload a copy of the command line version
of Wireshark (called 'tshark'), capture some network traffic to a
file, then download it and look at it with Wireshark. I've used
this feature a time or two, and it sure beats trying to use a GUI
program over a slow remote link!

This is a port of the libpcap and
tcpdump suite from Unix to Windows. They also have a GUI packet
capture program called Analyzer,
but the project seems to be abandoned, no doubt due to the popularity
of Ethereal.
WinPCap is the best way to get low-level network access in your own
programs, if you don't want to spend any money. Buying one of PCAUSA's kits may be a better choice
if your time isn't free, though.

I played with the demo, and found that I liked other Windows capture
programs a bit better.

Observer is one of the "big boys" of network monitoring tools. However,
between my initial passing review and a few reviews I've read in
magazines, this package does not look as though it will dethrone the
more popular packages any time soon.
