Hello

first of all I hope this is the right list to raise this issue...sorry if it's not...I'm trying to execute an embedded lua script with tshark. The lua script connects to a redis server running in the same in the same machine:
This is the relevant part of the lua script code:

require("redis")
require("socket")
call_db = 0
local redis_server = "localhost"
local redis_port = '6379'
-- Connection to redis server
redis = Redis.connect(redis_server,redis_port)
redis:select(call_db)
