# LMP Wireshark Dissector

## Usage

```sh

wireshark -X lua_script:LmpWiresharkDissector.lua

```

## Manual server list request

```sh

# Sends a server list request, static date

echo -ne "0000009000000001009bee15b40520da0800001c000000" | xxd -ps -r | cat > /dev/udp/116.203.125.175/8700

# The following gets the hex representation of the current ticks (=one ten millionth of a second) since 0001-01-01

printf %016x `echo $((($(date --utc +%s) - $(date +%s --utc --date "0001-01-01")) * 10000000))`

# Converts big-endian hex to little-endian hex (https://km.kkrach.de/p_bash_conversion/)

be2le() {

	[ -z "$1" -o "$1" = "-h" ] && echo "be2le: Converts zero-padded big-endian hex numbers to little-endian" && return 0

	echo "$1" | grep -o .. | tac | echo "$(tr -d '\n')"

}

# Combined

echo -ne "000000900000000100$(be2le $(printf %016x $(echo $((($(date --utc +%s) - $(date +%s --utc --date "0001-01-01")) * 10000000)))))00001c000000" | xxd -ps -r | cat> /dev/udp/127.0.0.1/8700

# or 00001d000000 for 0.29.0
