Spent the day researching high-availabilty firewalling, which is my nr. 1 choice for a diploma thesis at the moment. Found some good resources on the net. Stumbled over the linux ottawa conference 2004 audio recordings and consequently listened to some of them. Subscribed to the netfilter-ha, linux-ha and openbsd pf mailinglists. Yikes, so more daily email. Retrieved the 2004 archive from netfilter-ha and converted the mbox textiles with a nice perl script called, mb2md.pl to the Maildir format so that I can import the archived emails to my local imap account.
