Can I petition for this as a fix rather than a feature since the -i TCP@ works in the Linux builds but not in Windows?

Sure, as I replied, I was a bit too hasty (it's been a long day) and confused this change with another, to me it seems to be fix suitable for backport.

Ignore my last, I was confusing the change with another.  The Release policy still applies though.

Just to follow up.  I created bug #15149 and submitted a fix for review 29894 based on master.

Do I need to create a separate patch if I need this included in the next 2.6.x release?


Arguably this is a feature and so would not be a candidate for backport to 2.6.  See the Release Policy wiki page: https://wiki.wireshark.org/Development/ReleasePolicy

Core devs handle the backport if there is one.

Actually wireshark is not running on the Linux side and this is not using rpcap.

I am using the TCP@ sockets stream support built in to dumpcap rather than extcap or rpcap.

On the linux side I have a TCP server which generates PCAPNG data with SHB and IDB sent to any client connecting followed by EPBs.

I have wireshark/dumpcap 2.6.2 on Windows and Linux (Ubuntu 18.04) clients.

Hi,
 
I am trying to connect to a remote PCAPNG stream from Windows using the TCP@ socket interface but the connection closes immediately after connecting.  The same dumpcap command on linux works just fine to the remote TCP socket.
 
No errors indicating any failure are printed from dumpcap.exe
C:\>"\Program Files\Wireshark\dumpcap.exe" -i TCP@192.168.1.100 -w -
Capturing on 'TCP@192.168.1.100'
dumcap:
 
C:\>
 
On the remote end running in linux I see a connect and disconnect with EPOLLHUP event.
 
Has anyone else tried or have remote TCP socket connections working with dumpcap in Windows?
 
James
