This is useful when you don't want to go through the hassle with iptables and rtmpsuck. Sometimes the usage of rtmpsuck makes various Flash streams not working at all.
As an alternative to rtmpsucks, you can use ngrep:
Code:
ngrep -W byline | grep -Pio '(swfurl\.{2}.*?\.{2})|(\.{2}play.*?\w.*?\.{3})|(tcUrl.*?rtmp://.*?\.{2})|(pageUrl\.{3}.*?\.{2})'
