Bug ID: 261565
Summary: [tcpdump] [divert] Permit tcpdump to use a divert(4)
socket as a packet source
Product: Base System
Version: Unspecified
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: bugs@FreeBSD.org
Reporter: bsdpr@phoe.frmug.org
This is not a bug report but a feature request.
It would be extremely handy if tcpdump(1) could be able to use a divert(4)
socket as a packet source. It could even be handier if several of such sockets
could be used at the same time. For multi-socket operation, the port of the
source socket should be part of the dissection output.
The intended use is to help troubleshoot a defective ipfw ruleset live without
deferring through the ipfwpcap(8) intermediate step.
