MAC-Telnet for Posix systems
Console tools for connecting to, and serving, devices using MikroTik RouterOS MAC-Telnet protocol.
CURRENTLY UNDER DEVELOPMENT
Warning This repository is in mid-way of adding support for RouterOS v6.43 and up, which does not support the old MD5 authentication method. Expect this to be "alpha quality" for now. The new EC-SRP key sharing and authentication protocol is not implemented in
mactelnetdyet.
Installation
Docker
haakonn/mactelnet contains all four programs:
docker run -it --rm --net=host haakonn/mactelnet mactelnet …
docker run -it --rm --net=host haakonn/mactelnet macping …
docker run -it --rm --net=host haakonn/mactelnet mndp …
docker run -it --rm --net=host haakonn/mactelnet mactelnetd …
Note that Docker runs containers on isolated internal networks by default. --net=host instructs Docker to provide mactelnet direct access to the host machine's network interfaces.
See Usage for more.

Usage
# mactelnet -h
Usage: mactelnet <MAC|identity> [-h] [-n] [-a <path>] [-A] [-t <timeout>] [-u <user>] [-p <password>] [-U <user>] | -l [-B] [-t <timeout>]
Parameters:
MAC MAC-Address of the RouterOS/mactelnetd device. Use mndp to
discover it.
identity The identity/name of your destination device. Uses
MNDP protocol to find it.
-l List/Search for routers nearby (MNDP). You may use -t to set timeout.
-B Batch mode. Use computer readable output (CSV), for use with -l.
-n Do not use broadcast packets. Less insecure but requires
root privileges.
-a <path> Use specified path instead of the default: ~/.mactelnet for autologin config file.
-A Disable autologin feature.
-t <timeout> Amount of seconds to wait for a response on each interface.
-u <user> Specify username on command line.
-p <password> Specify password on command line.
-U <user> Drop privileges to this user. Used in conjunction with -n
for security.
-q Quiet mode.
-o Force old authentication algorithm.
-h This help.
Example using identity:
$ mactelnet main-router
Searching for 'main-router'...found
Login: admin
Password:
Connecting to d4:ca:6d:12:47:13...done
Example using mac address:
$ mactelnet -u admin 0:c:42:43:58:a5
Password:
Connecting to 0:c:42:43:58:a5...done

Tips
You can use the well known "expect" tool to automate/script dialogues via mactelnet!
List available hosts
# mactelnet -l
MAC-Ping usage
# macping -h
Usage: macping <MAC> [-h] [-c <count>] [-s <packet size>]
Parameters:
MAC MAC-Address of the RouterOS/mactelnetd device.
-s Specify size of ping packet.
-c Number of packets to send. (0 = for ever)
-h This help.
Example:
# macping 0:c:42:43:58:a5
0:c:42:43:58:a5 56 byte, ping time 1.17 ms
0:c:42:43:58:a5 56 byte, ping time 1.07 ms
0:c:42:43:58:a5 56 byte, ping time 1.20 ms
0:c:42:43:58:a5 56 byte, ping time 0.65 ms
0:c:42:43:58:a5 56 byte, ping time 1.19 ms
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 0.65/1.06/1.20 ms
Or for use in bash-scripting:
# macping 0:c:42:43:58:a5 -c 2 >/dev/null 2>&1 || ( echo "No answer for 2 pings" | mail -s "router down" my.email@address.com )
Huge thanks
Thanks to @comed-ian for creating a working proof of concept python script that successfully authenticated using the new authentication method in RouterOS 4.43+, and @kmeaw for porting the code to C, and implementing it in mactelnet.
