Getting alerts from an offline node

[rad]

Hi, Dave. I am still seeing phantom activity with the 1.08.1a version. This time it is with an offsite node that went offline briefly on Friday due to a power failure. On the node for the file server at that site registered a couple intervals of false activity. I've attached a screenshot of the graph. The green spaces in the red line are graphed at 0.1ms when you zoom in.

Hi,

Ok right let's try again - can you install 1.08.2a and see what happens? This checks just about everything to try and ensure the reply is geniune.

If that doesn't crack it then I'll send you a custom script to run which will record all the incoming and outgoing traffic from the test I can have a look at.

Regards,

Dave.

Thanks. I'll get this installed soon and get back to you.

I upgrade my dev vm to 1.08.2a. I'll keep you posted as to how things go.

Hi,

Not sure how you're getting on with this (or even if you've dumped it totally after your boot problems!) but I have spent the last few weeks playing with ICMP code off and on.

This weekend I wrote a standalone ping system (ppPing - http://www.purplepixie.org/phpping/) which should offer must more robust functionality for example missing out-of-sequence, mis-identified or ICMP errors.

I rather hope this will one and for all resolve any ICMP issues (but that is probably wishful thinking).

Anyway - 1.09.0a now uses ppping in place of the old internal ICMP functionality and is probably worth a shot at trying.
