Nagios Support Forum

Hello,

IP address of client machine: 10.147.108.45 (eu2napu002)
IP address of Nagios machine: 10.147.108.46 (eu2napu003)

As suggested by you, I again ran "tcpdump -s 0 -i any port 5666 -w output.pcap" and stopped it in around 30 secs.
I am attaching the output here.

I'm still not able to make sense of the data. Please open a ticket at http://support.nagios.com/tickets/ and reference this case and we can setup a remote to take a closer look.
