Mikrotik mac telnet linux

MAC access

MAC telnet is used to provide access to a router that has no IP address set. It works just like IP telnet. MAC telnet is possible between two MikroTik RouterOS routers only.

  MAC Telnet Server

  Property Description

  • interface (name | all; default: all) — interface name to which the mac-server clients will connect

  Notes

  There is an interface list in this submenu level. If you add some interfaces to this list, you allow MAC telnet to that interface. Disabled (disabled=yes) item means that interface is not allowed to accept MAC telnet sessions on that interface. all interfaces iss the default setting to allow MAC teltet on any interface. Example

  To enable MAC telnet server on ether1 interface only:

  [admin@MikroTik] tool mac-server> print Flags: X - disabled # INTERFACE 0 all [admin@MikroTik] tool mac-server> remove 0 [admin@MikroTik] tool mac-server> add interface=ether1 disabled=no [admin@MikroTik] tool mac-server> print Flags: X - disabled # INTERFACE 0 ether1 [admin@MikroTik] tool mac-server>

  MAC WinBox Server

  Property Description

  • interface (name | all; default: all) — interface name to which it is alowed to connect with Winbox using MAC-based protocol

  Notes

  There is an interface list in this submenu level. If you add some interfaces to this list, you allow MAC Winbox to that interface. Disabled (disabled=yes) item means that interface is not allowed to accept MAC Winbox sessions on that interface. Example

  To enable MAC Winbox server on ether1 interface only:

  [admin@MikroTik] tool mac-server mac-winbox> print Flags: X - disabled # INTERFACE 0 all [admin@MikroTik] tool mac-server mac-winbox> remove 0 [admin@MikroTik] tool mac-server mac-winbox> add interface=ether1 disabled=no [admin@MikroTik] tool mac-server mac-winbox> print Flags: X - disabled # INTERFACE 0 ether1 [admin@MikroTik] tool mac-server mac-winbox>

  Monitoring Active Session List

  Property Description

  • interface (read-only: name) — interface to which the client is connected to
  • src-address (read-only: MAC address) — client’s MAC address
  • uptime (read-only: time) — how long the client is connected to the server

  Example

  To see active MAC Telnet sessions:

  [admin@MikroTik] tool mac-server sessions> print # INTERFACE SRC-ADDRESS UPTIME 0 wlan1 00:0B:6B:31:08:22 00:03:01 [admin@MikroTik] tool mac-server sessions>

  MAC-Telnet / MAC-SSH Client & Server for connecting to Mikrotik RouterOS and Linux Boxes via MAC Address

  Updates

  About

  Open source MAC Telnet client and server for connecting to Mikrotik RouterOS routers and Linux machines via MAC address.

  Based on MAC-Telnet the original work of haakonnessjoen ( Håkon Nessjøen ); forked the upstream version to add forwarding mode for tunneling a TCP connection through MAC-Telnet protocol, and implemented MAC-SSH client and server functionality for tunneling SSH protocol instead of implementing shell interface directly.

  Unless you will be using any of the additional functionalities, I recommend using the Original Version from haakonnessjoen ( Håkon Nessjøen ) instead.

  For information on other projects you can check my GitHub Personal Page and GitHub Profile.

  Differences

  The original version implements the following:

  • A Linux console tool for connecting to MikroTik RouterOS devices via their Ethernet address.
  • Linux daemon that implements the MAC-Telnet server to permit connecting to Linux machines via their ethernet address.

  The forked version implements additional functionality for forwarding a TCP connection through the MAC Telnet protocol. The main use case is connecting to Linux machines via their Ethernet address using the SSH protocol for security. Take note that the clients and servers running in the forwarding mode are not compatible with existing MAC-Telnet clients and servers implementing the standard mode of operation.

  The forked version of the server supports two modes of operation: * Standard MAC-Telnet Server Mode * TCP Connection Forwarding Mode: Tunnels a TCP connection to a local port on the client to a specific local port on the server side through MAC-Telnet protocol. This mode of operation is used for forwarding SSH connections through the MAC-Telnet protocol.

  The client supports three modes of operation: * Standard MAC-Telnet Client Mode * TCP Connection Forwarding Mode: Tunnels a specific local port on the client to the serverthrough MAC-Telnet protocol. * SSH Forwarding Mode: Apart from setting up the tunnel, the client takes care of launching the SSH client.

  Standart MAC-Telnet Mode [MAC-Telnet Cli] ---UDP---> [MAC-Telnet Srv] TCP Connection Forwarding Mode ---TCP---> [MAC-Telnet Cli] ---UDP---> [MAC-Telnet Srv]---TCP---> SSH Forwarding Mode [SSH Cli] --->TCP---> [MAC-Telnet Cli] ---UDP---> [MAC-Telnet Srv] ---TCP---> [SSH Srv]

  The SSH Forwarding Mode has the following advantages in comparison to standard MAC-Telnet:

  • The_mactelnet.users_ configuration file is not needed. Instead of maintaining another set of user passwords for MAC-Telnet, the authentication mechanisms implemented ssh are used.
  • Public Key Authentication works seamlessly permiting passwordless logins.
  • The communication between client and server is encrypyted by SSH.
  • The daemon does not require root privileges and can be run by a non-privileged user for additional security. In case the -n option is used, the server or client must be launched as root user, but the-U option can be used to drop privileges once the initial setup phase ends.
  • The server relies on the security model of SSH, instead of creating a shell environment itself.

  Use Cases

  Embedded Systems

  It can be used for initial provisioning and for maintenance purposes in situations where a valid IP configuration is not available.

  Might be a useful addition to the rescue mode especially of embedded systems without screens; connecting using MAC-Telnet / MAC-SSH is much more convenient then fetching and connecting a serial cable.

  The Datacenter

  It can be used for initial provisioning of physical and virtual servers and might serve as a rescue system, when the IP configuration of a server gets messed up for any reason.

  Usage

  mactelnet

  Usage

  $ mactelnet -h Usage: mactelnet [-v] [-h] [-q] [-n] [-l] [-S] [-P ] [-t ] [-u ] [-p ] [-c ] [-U ] 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 Amount of seconds to wait for a response on each interface. -u Specify username on command line. -p Specify password on command line. -U Drop privileges by switching to user, when the command is run as a privileged user in conjunction with the -n option. -S Use MAC-SSH instead of MAC-Telnet. (Implies -F) Forward SSH connection through MAC-Telnet and launch SSH client. -F Forward connection through of MAC-Telnet without launching the SSH Client. -P Local TCP port for forwarding SSH connection. (If not specified, port 2222 by default.) -c Path for ssh client executable. (Default: /usr/bin/ssh) -q Quiet mode. -v Print version and exit. -h Print help and exit. All arguments after '--' will be passed to the ssh client command. 

  Examples

  Establish standard MAC-Telnet session with remote box:

  $ mactelnet -F -P 4001 aa:bb:cc:dd:ee:ff 

  Establish SSH connection with remote box:

  $ mactelnet -S -u root aa:bb:cc:dd:ee:ff 

  Establish SSH connection with remote box, forwarding additional ports using SSH Port Forwarding:

  $ mactelnet -S -u root aa:bb:cc:dd:ee:ff -- -L8080:127.0.0.1:80 -L443:127.0.0.1:8443 

  mactelnetd

  Usage

  $ mactelnetd -h Usage: mactelnetd [-v] [-h] [-n] [-f] [-S] [-P ] [-U ] Parameters: -f Run process in foreground. -n Do not use broadcast packets. Just a tad less insecure. -S / -F Forwarding of TCP connections through MAC-Telnet protocol, instead of using the standard MAC-Telnet remote terminal. -P Local TCP port used for forwarding connections to SSH Server. (If not specified, port 22 by default.) -U Drop privileges by switching to user, when the command is run as a privileged user in conjunction with the -n option. Standard MAC-Telnet is not compatible with this option. -v Print version and exit. -h Print help and exit. 

  Examples

  Launch MAC-Telnet Daemon for receiving Standard MAC-Telnet protocol connections:

  Launch MAC-Telnet Daemon for forwarding connections to local SSH Daemon listening on port 22:

  Launch MAC-Telnet Daemon for forwarding connections to local SSH Daemon listening on non-standard port 2222:

  macping

  Usage

  $ macping -h Usage: macping [-h] [-f] [-c ] [-s ] Parameters: MAC MAC-Address of the RouterOS/mactelnetd device. -f Fast mode, do not wait before sending next ping request. -s Specify size of ping packet. -c Number of packets to send. (0 = unlimited) -h This help. 

  Examples

  mndp

  Usage

  Examples

  Troubleshooting

  Disable firewalls both on the client and server side for testing. Firewalls can block the forwarding of packets with broadcast addresses even when they are not blocking any ports.

  The server can be run in the foreground (commanline option: -f) for testing.
