Recently, I needed to roll a port back to a much older revision. While I usually dislike this type of thing, I found it to be necessary this time. Somebody recommended that I use portdowngrade to revert the ports tree to the older version, so I could install it.

to test the speeds after mounting it. I observed horrific speeds (in the range of 300-500KB/s).

The other night, I noticed that popsicle.easymac.org’s mailq was >22,000 message. I figured that was a problem. Turns out one of my users (who’s account I deleted without hesitation) was running a PHP proxy from his ~ directory. Looks like the stupid thing allowed some idiot to download some obnoxious looking perl [...]
