Try pingplotter http://www.pingplotter.com  , with this tool you can send alerts (send an e-mail, play a sound, launch an executable...) The tool don't send SMS but in UK you can try http://www.kapow.co.uk , you  generate an Can anyone suggest a good ping prog for meshboxes. Usual issue. We all get node crash and they require a reboot. This is easy, however it would be good to know when a node is "dead". The usual progs that sms to admin are no good within a mesh for obvious reasons. Ping checkers are ok, however I would like to see something that perhaps will sound an alarm on a pc if a node goes down!! Any ideas.

How do you avoid this problem you describe? And still have dual radios? but they draw a lot of power and if you're putting two of those on a single bus you have to consider whether they'll suffer interference (which I think is very likely)

The only hardware I can really recommend is that which has passed complete lab and field tests. So far that is the mini-itx based units you see on sale in the locustworld shop. I've looked at a number of boards but nothing with a better price / performance ratio has ever completed full testing.

Senao cards are generally good, but they draw a lot of power and if you're putting two of those on a single bus you have to consider whether they'll suffer interference (which I think is very likely) and whether the bus can even support the peak drain of the cards, if it can't then it will crash and it's likely to do this fairly randomly but generally under higher loads.

As for the power over ethernet hookup you describe. I don't know enough electrical engineering to really work out whether that would supply enough power within the tolerances of the particular board to work correctly. I've tried wherever possible to stick to tried and tested solutions and off the shelf equiment rather than any home brew stuff.

I would recommend replacing the unit with a mini-itx based one if you're having problems with stability. If you need power over ethernet then try a unit similar to the one Joel recently recommend, I believe he's had good success with them. If you don't want to do that, then try changing one of the aspects of the node, such as the radios, the power hookup etc.
