		<title>Testing multicast</title>
		<description><![CDATA[TCP is the protocol that gets the most attention, and that makes some sense as it&#8217;s the one that carries your email and web pages, the two most popular applications on the net.   There are times, though, when TCP is not appropriate, like when you want to multicast data to several machines at once.
Multicasting takes [...]]]></description>

		<title>FAST_IPSEC is now IPSEC in FreeBSD</title>
		<description><![CDATA[As of about 2 weeks ago the IPsec implementations in FreeBSD were changed such that the old, Kame, IPsec is no longer in the system, and the system that was once called FAST_IPSEC is now the official IPsec of FreeBSD.
What does this mean to you?

Â FreeBSD IPsec is now MP Safe, which is a requirement for [...]]]></description>

		<title>Keeping time in a Virtual Machine</title>
		<description><![CDATA[Â Unlike suspend/resume on a laptop the guest operating system in a Virtual Machine doesn&#8217;t know when it has gone to sleep and woken up.  The best way to get it to keep time correctly is to use ntpd (see ntpd(8) and ntp.conf(5)).
In order to keep ntpd running you have to tell it not to [...]]]></description>

		<title>Remote GDB on VMWare</title>
		<description><![CDATA[One of the reasons to use virtual machines is that they make kernel debugging easier.  No messing about with serial cables anymore, the simulator provides you with virtual serial ports, which to the operating system look just like real serial ports.  In this entry I&#8217;ll explain how to use remote GDB with VMWare [...]]]></description>

		<title>Announcing the Packet Debugger</title>
		<description><![CDATA[In order to facilitate the debugging of networking code I have used my library, &#60;a href=http://pcs.sf.net&#62;Packet Construction Set aka PCS&#60;/a&#62; to write a program I call the &#60;a href=http://pktdbg.sf.net&#62;Packet Debugger (pdb)&#60;/a&#62;.  All of this is written in Python and available under a BSD license.  The blurb from the pdb web page gives you [...]]]></description>

		<title>Configuration Files for FreeBSD Development on Parallels</title>
		<description><![CDATA[This post points to two files, PARA, my kernel configuration file, and loader.conf which sets the kernel&#8217;s HZ back to 100.  The default hz in FreeBSD CURRENT (will be 7.0) is now 1000 which is too high for Parallels to keep up with and causes it to eat about 15% of the CPU on [...]]]></description>

		<title>Parallels Desktop as a Network Development System</title>
		<description><![CDATA[Â As some of you may, or may not know, I tend to do a lot of my kernel development in virtual machines, such as &#60;a href=www.vmware.com&#62;VMware&#60;/a&#62; and now &#60;a href=http://www.parallels.com/&#62;Parallels&#60;/a&#62; on my MacBook.  I find that virtual machines make the perfect test lab because you can easily create, copy, store, backup and delete them. [...]]]></description>
