BTW, comms/conserver-com port is of great use > for this purpose! I have an 8 port serial Boca card here, which I have yet to get running. How does comms/conserver-com work? I couldn't determine that from the FAQ. Does it need any hardware? How does it monitor the serial console? Do you connect two boxes together via their serial ports? Box A reports on Box B, and vice versa? Or does it just monitor the serial console and report back to a central server? > I assumed here that usually you have more than one machine per physical > location; otherwise, I'd set up remote logging, preferrably to two different > machines via two different interfaces, but such ideal network design is > *rarely* reqchable ;-) I have one location which has only one box. That box and the bandwidth is kindly donated by BCHosting.com, and hosts freebsddiary.org, freshports.org, etc. It does about 45GB a month (at last check). I'd like to have a serial console there. But if it could the console remotely, that would be good. Cheers -- Dan Langille : http://www.langille.org/
