After 72 hours the USB webcam is still running. No signs of memory leaks or other problems. Looks like the 2.3.99 kernel is begining to be pretty stable. Back around 2.3.62, the USB/CPiA combination would blow up after about 24 hours.
We had a close call with someone trying to crack our machines last night. We get seemingly constant port scans and crack attempts these days anyway. In this case someone had cracked a machine at our upstream ISP with an IP that was specifically allowed to get through our outer security layers. Fortunately they weren’t very good. They spent a couple of hours trying buffer overflow exploits on ftpd on several of our servers and then gave up. Made for a few minutes of excitement this morning though.
