RE: iACS have cwbping?

[Justin Taylor <JUSTIN@xxxxxxxxxxxxx>]

I my case, I had an unexplained outage that's got IBM scratching their heads (their answer is to wait for it to happen again and get a Main Storage Dump).  Our network people have a commercial solution that does normal ping tests, but my system answered pings (it just didn't do anything else).  So I'm trying to put a together a tester than can check availability.

In addition some so called 'intelligent' firewall modules which decide that traffic on this or that port doesn't conform to traffic patterns the module knows and thus shuts you down.

Currently the cisco 'fire at will' (firepower) module is on my 'most hated' listed. So far it has been confirmed to terminate PTF downloads (claiming they are oversized PDFs LOL!) as well as POWERHA traffic. I have only one customer who purchased that module who is still using it.
