What's Here?

This is my "attic" of technical notes. A tech note typically comes into being when I try to solve a problem and find myself spending considerable time to hunt down the right answer by sifting through the vastness of the Web. The essence of what I find occasionally condenses into a tech note for the purpose of being shared here. All information is provided "as-is" (I appreciate corrections of errors). Some information may be outdated.

    Running OpenBSD off a USB Stick.
    Technical Note 1, February 2007.
    USB sticks with a capacity of 512MB or more are becoming cheap. OpenBSD can run off such a USB stick and operate nicely without a hard drive. This is very useful to build VoIP or firewall appliances. We describe essential configuration steps of such a setup.

    Setting Cisco 7905G Phones up With Asterisk.
    Technical Note 2, February 2007.
    Asterisk is a software PBX and Cisco produces SIP phones which can be configured to work with Asterisk. In this technote, we describe what steps must be taken to configure a Cisco 7905G phone for the Asterisk PBX. The process should be similar with other phones, particularly Cisco ones.
