I am running Dude version 2.2 and have had serious issues with Dude ping timeouts in our network. Pings from the CLI work fine. Dude initiated pings timeout on several different manufacturer devices. I took a look with ethereal to see what may be happening. Some results:
1. Ethereal shows pings being sent. However, I see 3 pings sent within two second for my devices. Why is this happening?
2. I do not see ping responses from devices that are timing out. However, if I issues a reprobe form Dude, the device immediately responds. Why would that be? I can reprobe after a set of the 3 pings are sent and the device will respond correctly.
I'm forwarding the packet dump to you.
