High Linux uptime

Saturday, June 22nd, 2002

My no-name white box (P200, 64M, Red Hat 7.1) had 231 day uptime when
I had to shut it down to add more memory and get ready to replace it
with a home built AMD 1.8G running debian ‘woody’. The previous white
box system was a P486/33 with 24M running Red Hat 6.2. A 6x speed bump
then 9x. In a few years will the next one be a 21.6G monster?

$ uptime
9:36am up 231 days, 11:01, 1 user, load average: 0.04, 0.03, 0.00

				

Teaching SpamAssassin about the Microsoft KLEZ virus

Thursday, June 13th, 2002

Adding lines like the ones below does a pretty good job about tagging
the KLEZ virus as spam. It does miss some of the KLEZ variations
because the KLEZ_CONTENT is slightly different.

$ grep -i klez /usr/share/spamassassin/*
/usr/share/spamassassin/20_body_tests.cf:rawbody KLEZ_IFRAME            /iframe

I put filters for mailing lists that are for the most part spam-free
above these to entries and those lists that are spam-heavy below it.
