hey, guys. here's a solution that smells much more like unix. have a daemon running on each node that is prone to hangup. this process wakes up every once in a while and does a system checkup. (stats things, pings places, looks at kernel statistics). when it see that things are ok, it sends a datagram to a particular machine, this node, the monitor, has a table in memory of all recent datagrams from each node. when a node hasn't been heard from for a while, it tells a BSR x10 controller to cycle power on the hung node. DUH. our ISP, tlg.net used to do routing and slip with sx-16's running NOS. whenever a hang happened, tlg used to do a power cycle with X10's. curt
