tcpdump filter for out/in traffic

[KES]

Здравствуйте, Questions.

There will be very usefull to have options for tcpdump to monitor
incomint or outgoing traffic regardless of src/dst IPs or ports or protocol

For example:

kes# tcpdump -n -i rl4 out
EXPECTED: show traffic outgoing on rl4
ACTUAL: tcpdump: syntax error


kes# tcpdump -n -i rl4 in
EXPECTED: show traffic incoming on rl4
ACTUAL: tcpdump: syntax error
