I am now testing with HIs in my DNS starting with conntest.Tests work fine, I might point out that I discovered I had seriour problems with my homegrown IPv6 router/firewall, and by turning off ip6tables, I may be running exposed, but data is flowing!
But I have a problem with tcpdump. Absoluting nothing in the dump. My command is:
tcpdump -n -i eth0 esp or proto 139 or port 50500I do get a warning that there are no IPv4 addresses on eth0. Also verbose suppressed, and eth0 is type EN10MB (supprises me, I would have thought the unit would be doing 100Mb, will have to look into that).
Any idea why tcpdump is not capturing anything or what to add?
