These are my links for 5 lug 2012 through 6 lug 2012:
NetHogs: What program is using that bandwidth? – NetHogs is a small 'net top' tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there's suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to indentify programs that have gone wild and are suddenly taking up your bandwidth.
If you wish to have LiveCD/LiveDVD instead, please refer to our other LiveCD-OpenBSD project on sourceforge!

Jon Hart’s Blog: OpenBSD on Soekris — A Cheater’s Guide – Below are the steps I recently used to get my NET4801 running OpenBSD 4.2 -current. The difference here is that I use qemu to make use of the considerably faster CPU on my desktop to breeze through the install and initial configuration.
TCP Traffic Analyzer (Yahoo! Developer Network Blog) – You probably have questions like these about traffic on a TCP (Transmission Control Protocol) server (or client):<br />
* How many connections lasted more (or less) than X milliseconds?<br />
* How many connections needed more than N attempts to succeed?<br />
* What is the distribution of connection duration or connection throughput?<br />
* What is the distribution of connection duration or throughput for connections in which the server or client sent more than N bytes?<br />
* What specific IP addresses and ports had connections that lasted between 50 and 100 milliseconds long?<br />
You can get answers to these questions (and more) using Yahoo!'s TCP Traffic Analyzer (yconalyzer), available as an open-source project via free download.
