[Mono-list] Mono.zeroconf timeouts or refresh / rescan ?

[Mark Jackson]

I'm using mono.zeroconf under XP + bonjour.

My simple application lists particular devices as and when they appear on our network.

These devices are Linux boxes running avahi, and when they are powered up / down correctly my application adds / removes the devices from a list.

However, if the power is simply removed from one of the devices (i.e. avahi does *not* shut itself down nicely on the device), that device's services remain visible.

I can detect this by pinging the devices and removing them from the list if I get a ping timeout / etc.

But is there a nice "zeroconf" way to detect that a device has disappeared ?

Can I ask zeroconf to rescan / rebrowse the network ?

Or is ping / timeout the only method available ?

Thanks
Mark
