TCP Dump and libpcap
Wireshark
Libpcap is a very simple library to get the data from packet capture files. TCP Dump is a program that captures data from interfaces. It can also print the data it captures in realtime or later. Wireshark is a GUI program that reads cap files (and can also capture data) and displays the information very well.

GPG is an easy and open source public key encryption solution. Many e-mail
clients support it as well as a few IM clients. Neg9 uses
GnuPG for secure e-mails. Crash's key
expired recently, which allowed us to discuss how to update the key. Crash
already generated a new key which he signed with his old key. You can download
his new key at his website. When you import
the key
gpg --import crash_pub.asc, it will be properly usable.
with the signatures that you may have done during a keysigning with Crash's old
key.
Greetings, I'm Javantea author and founder of AltSci Concepts. I've written 25 essays for 4.5 issues of AltSci Concepts Computer Journal. I will continue to do so at my leisure. I added a comment system to provide a public method of feedback. Now that I'm more confident, I'd like to add a third method of feedback. Readers can now buy public hacks from AltSci Concepts. Click the button at the top or bottom of this page to buy a hack for US$5.
First off, let me discuss the terms of the purchase. The cost of the "public hack" is $5. You are purchasing a guaranteed article with code and data on the topic of your choice. In fact, I will not taboo any topic. I guarantee delivery via e-mail or web in less than 30 days (much less if a reasonably easy topic). At my discretion I will publish the results on AltSci Concepts. If you wish the results to be private, my fee is $20 per hour, my normal developer rate. The product is subsidized by the fact that it will be published on AltSci Concepts as public knowledge.
Now I will give examples of projects that could be bought for the low low price of $5.

Spam servers are generally accepted to be among the worst netizens currently residing on the net. Most are zombie botnets, some are open relays or proxies, but some are legitimate businesses in foreign countries. Since spam is illegal in the US, any server sending spam (with quite a few exceptions) is committing a crime. Of course, legislators have no concept of legitimate enforcement, so the fact that spam is a crime does not affect the level of spam that users receive.
Detection, analysis, and blacklisting of spam servers is the proper method to eradicate spam servers. While certain methods of unblacklisting will be required, blacklisting has no downsides. Occasional spammers will not be blocked until they make themself a nuisance.
