It seems like the desired functionality is to inject a "marker" packet into the
capture? If so, you could use an external program, something like ping or nc,
to do that. I tend to use a separate script for this, something such as:
#!/bin/sh
if (( ${#} < 1 ))
then
echo "Usage: $0 <message> [host]"
exit 0
fi
if (( ${#} < 2 ))
then
# Send a syslog message $1 to host 1.1.1.1
echo "${1}" | nc -w 1 -u 1.1.1.1 514
else
# Send a syslog message $1 to the host $2
echo "${1}" | nc -w 1 -u ${2} 514
fi
However, if you want something like this integrated with Wireshark, then it is
possible with Lua. Here’s a sample “proof-of-concept” Lua script that will
send a packet whenever you click the send button. I successfully tested this
on Windows (with Cygwin tools installed for nc) , but I did need to run
Wiresahrk as an administrator for this to work. I’ve illustrated two commands,
ping and nc, but you can tailor it however you wish. Here’s the contents of
the marker.lua file that you can experiment with:
if not gui_enabled() then
return
end
local count = 1
local function marker_window()
local win = TextWindow.new("Marker");
win:set("Marker " .. count)
win:add_button("Send", function()
-- Choose a command; here are a couple of examples:
local cmd = "echo " .. win:get_text() .. "| nc -w 1 -u 1.1.1.1
514"
--local cmd = "ping -n 1 -l 100 1.1.1.1"
os.execute (cmd)
count = count + 1
win:set("Marker " .. count)
end)
end
register_menu("Marker", marker_window, MENU_TOOLS_UNSORTED)
You can call it splat.lua and rename “Marker” to “Splat” if you prefer that.
The file should be stored in your Wireshark plugins directory. If Wireshark is
running, you’ll need to restart it. Refer to
https://wiki.wireshark.org/Lua/Examples#dialogs_and_TextWindows for more
information or to the Lua section of the Wireshark Developer’s Guide:
https://www.wireshark.org/docs/wsdg_html_chunked/wslua_menu_example.html.
Hope it helps.

Subject: Re: [Wireshark-users] Newbee - propose Splat Button
Thanks Jaap.
I am on the Fedora31. When I hit Edit->Mark Packet, nothing happens - no
mark... Ahh, when I move cursor off packet to be marked, I see marked packet as
white on black rather than white on blue.
The functionality I'm looking for is to actually store the user button
(splat) in the saved file. But maybe I don't need that if I just keep Wireshark
open on my screen. Also, other users may use the saved file for other purposes
- parse and act. Having a splat actually in the saved file might not be so
good. But then, those folks probably would not be looking at the screen anyway.
I will do my experiments again (and again) and use the Mark feature. It may be
good enough.
Thanks much - BobG
