# Background: tcpdump of bgp has lots of noise due to keepalive packets

# filter the packets
# port 170 -> default BGP port
# (tcp[tcpflags] & tcp-push != 0) -> output can be difficult with ACKs so only keep PSH
# ip[70] != 0x04 -> a bit of trial and error and examining with -X flag, see https://en.wikipedia.org/wiki/Border_Gateway_Protocol#Message_header_format
sudo tcpdump port 170 and (tcp[tcpflags] & tcp-push != 0) and ip[70] != 0x04

# then, add timeout or packet counter
sudo timeout -k 1s 10m tcpdump ... -w /tmp/yourfile.pcap

Alternative Schooling

Below is an amalgamation of link and concepts that may help you prepare for any mix of development and operations.

Building a Product

The easiest way to "learn what you need to learn" is to build a product. The first step in building a product is:

Solve a problem that someone actually has

# NOTE: any 'chunkc' command that is run from this config file
#       that is NOT 'chunkc core::<..>' or 'chunkc set ..'
#       MUST be put in the background using &
#
#       e.g:
#       chunkc tiling::rule --owner Finder --name Copy --state float &
