I have an annoying problem with my Openswan VPN server. When I connect from a Windows XP machine, from that point on, I can only connect with that machine (or perhaps other Windows XP machines as well).

I had a disk in one of my servers that was starting to give ATA errors in the syslog. Contrary to what you might think, ATA errors are fairly common, so I didn't immediately sound the alarm.
