I have a simple question that I'm trying to wrap my head around. I know this requires knowledge of my internal network, but at a glance, what do you guys think..
I cannot ping a host in my network (nor can I arping the host), however nmap can detect the host.
Does this mean I have connectivity to the host? Or am I dead in the water?
I have a route to the host in my routes, and iptables is disabled on my server (rhel6).

Nmap scan report for mdc001 (192.168.6.5)
Host is up (0.00017s latency).

Nmap scan report for mdc002 (192.168.6.6)
Host is up (0.00018s latency).
MAC Address: 12:34:56:78:90:AB (Hewlett Packard)
(MAC's modified for obscurity).
What gives? Am I able to communicate with the host or not? Also, there were link-local routes for the interface on that network (bond2), but I removed them just in case.
