thanks, it works now after enable (Try heuristic sub-dissectors first).

We support only v2 and you need to enable a Preferencd on TCP dissector to
enable subdissector heuristic (don’t remember the exact name of pref)

check with development branch win64 Version 2.9.0-1583-g0fa2b0bf
(v2.9.0rc0-1583-g0fa2b0bf) , it cannot get the proxy protocol packet with
filter "proxy". And when choose the proxy protocol packet to "Decode As", there
is no option for proxy.
I'm not sure I use it coorectly, could you please give some advices on how to
use proxy to decode proxy protocol packet? or is there another build is OK to
support proxy protocol?

There is only nightly build for merged patch and no nighty build for Linux...

Awesome Alexis, thank you very much for making this happen so quickly.

I see that your code still goes through code review, but at least one build has
been done already - https://code.wireshark.org/review/#/c/10626/.

Are there any nightly / unstable builds for Linux available which I could test?
https://www.wireshark.org/download/automated/ seems to only have OSX and
Windows.

Hi Christian,

A more working dissector for PROXY(v2)
https://code.wireshark.org/review/#/c/10626/ but need some work before merging

Hey Alexis,

did you get to check out the PCAP files I provided?
Is there anything else I could provide to help you finish the dissector?



Thanks again for taking the time and effort to implement this.

Christian

--- Comment #6 from christian.rohm...@inovex.de ---
I attached three PCAP files. Each file contains an MQTT CONNECT done over a
HAProxy instance.

1) The first "send-proxy-v2" is without any SSL.
2) Then "send-proxy-v2-ssl" with TLV containing info regarding SSL
3) Last but not least with option "send-proxy-v2-ssl-cn" and using a client
certificate (MQTT client -> HAProxy) of which HAProxy then forwards the CN
(CommonName) field via PROXY protocol TLV.

--- Comment #2 from christian.rohm...@inovex.de ---
Hey Alex,

thanks for the lightning quick reply.
I will get you some sample PCAPs of TCP traffic containing PROXY protocol v2
traffic.



In the meantime, may I point your to 


1) https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt

Or more particular section "9. Sample code", which contains some code to disect
the TLV fields of the protocol already.


2) https://github.com/aws/elastic-load-balancing-tools/tree/master/proprot

An implementation of PROXY-protocol-v2 parsing in Java, done by AWS (AWs
Network Loadbalancer - NLB supports PROXYv2) themselves.




Maybe this helps more than the LUA code I referenced to get a dissector going?





Thanks again for taking the time to implement this highly anticipated feature!
Regards

Christian

Hi Chritian,

i have already start (a longer time ago) for write a PROXY dissector (but for
v1)

v2 will be more easy to implement because it is a binary protocol... but
missing a pcap for write the code :-)
