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).
192.168.6.0 0.0.0.0 255.255.255.128 U 0 0 0 bond2 --- 192.168.6.5 ping statistics --- 6 packets transmitted, 0 received, 100% packet loss, time 5212ms --- 192.168.6.6 ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1097ms Nmap scan report for mdc001 (192.168.6.5) Host is up (0.00017s latency). MAC Address: 12:34:56:78:90:AB (Hewlett Packard) 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.
