MAC-Telnet for Linux

Console tools for connecting to, and serving, devices using MikroTik RouterOS MAC-Telnet protocol.

Installation

Then download source tarball, extract, compile and install:

wget http://github.com/haakonnessjoen/MAC-Telnet/tarball/master
tar zxvf haakonness*.tar.gz
cd haakonness*/
make all install

Now you're ready.

TIP: You can use the well known "expect" tool to automate/script dialogues via mactelnet!

Usage

# mactelnet -h
Usage: mactelnet <MAC|identity> [-h] [-n] [-t <timeout>] [-u <user>] [-p <password>] [-U <user>] | -l

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. (using MNDP)
  -n             Do not use broadcast packets. Less insecure but requires
                 root privileges.
  -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.
  -h             This help.

Example:

$ mactelnet 0:c:42:43:58:a5 -u admin
Password: 
Connecting to 0:c:42:43:58:a5...done

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 )
