I have a SATA drive in an ventilated external USB enclosure connected 24/7 to a NSLU2 running Debian arm (soon to be armel). It has the filesystem on it so it stays on all the time. It has<br>been up for a few months and I only reboot it after flashing the kernel. I don't forsee any problems of leaving it on all the time.<br><br>I also have an ALIX embedded firewall from Netgate with the intention of running OpenBSD on it. I got it configured with pfsense since I don't have a CF reader yet. From the pfsense webgui, I noticed that you can send Wake-on-LAN packets to machines on your network. I'm going to be able to turn on my fast OpenBSD testbox this way and not have to leave it running all the time.<br><br>Is it possible to send WOL packets in OpenBSD? If you have a similar setup, you can keep the drive in another machine with a WOL enabled NIC and use it on demand. <br><br>> Date: Mon, 27 Oct 2008 18:27:44 -0800<br>> From: brakeb@gmail.com<br>> To: openbsd-newbies@sfobug.org<br>> Subject: power down USB<br>> <br>> I have an ALIX box with two USB ports on it.
