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?

In order to keep ntpd running you have to tell it not to [...]

I’ll be adding more posts about working with virtual machines in the near future.

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’ll explain how to use remote GDB with VMWare [...]
