tcpdump -A port 50 output is tcpdump: verbose output suppressed,
use -v or -w for all protocol decode listening on eth0, link-type EN10MB
(Ethernet), capturing size 65535 bytes, and a blinking cursor which I
left for 20 min and re-started, tried with -v got listening on eth0,
type EN10MB (Ethernet), capture size 65535 bytes. re-started and meant
to use -w but forgot and just typed tcpdump. That gave tons of output
which I can't fathom and let it go for 30 minutes. Re-started one more
time and pinged nytimes.com That returned screenful of data packets
all ok. Then shutdown til tomorrow.
