I have this partial Lua Script which is working perfectly with Wireshark:
local function appl_rtt_dialog_menu()
local win = TextWindow.new("Application Latency");
local label = ""
local tot = 0
local i
i = 0
label = label .. "Server\t\tMin Application RTT\n"
for k,v in pairsByValues(min_appl_RRT, rev) do
label = label .. string.format("%-20s\t%.3f / %.3f msec\n", shortenString(k), v, max_appl_RRT[k])
if(i == max_num_entries) then break else i = i + 1 end
end
win:set(label)
win:add_button("Clear", function() win:clear() end)
end
I am trying to modify it for using in Tshark. since the script is written for GUI and Tshark has none, I change it in order to print to the console:
do
local function appl_rtt()
local label = ""
local i
i = 0
label = label .. "Server\t\tMin Application RTT\n"
for k,v in pairsByValues(min_appl_RRT, rev) do
label = label .. string.format("%-20s\t%.3f / %.3f msec\n", shortenString(k), v, max_appl_RRT[k])
print(label)
if(i == max_num_entries) then break else i = i + 1 end
end
end
appl_rtt()
end
but there is no output.
tshark -r test.pcap -X lua_script:test.lua -q
does anyone know how to change the script?
I have fixed it with Listener() and draw() functions.
