Getting WWAN to work at full speed on a T61p (28 Jul 2008)

I recently got a Lenovo T61p with a nice data plan, but found that by default, Ubuntu 8.04 didn't give me the full speed of the onboard Sierra Wireless MC8755 device. After some trial and error and some Googling, I got it working at full speed and put the effort into words here.

Pheasting on the Crumbs of Misconfigured Networks (31 Jan 2006)

This is a PDF of a paper I wrote last year about poorly configured DNS resolvers. While it's not rocket science, it's interesting that it happens as often as it does. Watch this space for updates to statistics. (Keywords: phisting, dns, resolv.conf, isa server)

Configuring the Exim MTA for SMTP AUTH and TLS (2005?)

SMTP AUTH is great. Configuring your MTA to support this ensures that all your users can use the mail server when they're out on the road. But unless you ensure that the session is encrypted, your users' credentials may find themselves in the hands of spammers or worse (ensure that your server's certificate is trusted to prevent man-in-the-middle attacks!). Configure Exim so that it supports TLS, then have a look here for a quick description on how to configure SMTP AUTH securely.

Wonder what 'lomscan.exe' is? (ca. 2001)

It's part of an attacker's toolset. A short note on it can be found here.

Need a simple configuration for a Cisco ISDN (BRI) router? (ca. 1999)

Look here. This works (worked?) with BT ClickFree. Probably a discontinued product now.
