# mactelnet(1)

A tool for telneting via MAC addresses

## NAME

mactelnet - A tool for telneting via MAC addresses

## SYNOPSIS

**mactelnet** \[*options*\] \<*MAC-Address*\|*hostname*\>

## DESCRIPTION

This tool enables you to telnet other RouterOS or MAC-Telnetd enabled devices. You can connect to either a hostname or a MAC address. If specified, the hostname (identity) will be looked up via MNDP discovery.

## OPTIONS

These programs follow the usual GNU command line syntax. A summary of options is included below.

- **-l**

  This will discover RouterOS or MAC-Telnetd enabled devices. It will list the MAC-address software version, and uptime of every device or machine it discovers. To exit the discovery, use **Control + C** .

- **-n**

  Do not use broadcast packets. A tad less insecure but requires root privileges. This means that ethernet packets will have the specified mac-address as the packet destination, instead of using the ethernet broadcast address.

- **-t**

  Amount of seconds to wait for a response on each interface. If you have several network interfaces, this is the timeout value per interface.

- **-u**

  Specify username. Without this option, you will need to enter the username in a interactive prompt.

- **-p**

  Specify password. Without this option, you will need to enter the password in a interactive prompt.

- **-a**

  Specify the path of the autologin configuration file. The default path for this file is ~/.mactelnet. The format for this file is standard INI file layout.

- **-A**

  Do not use the autologin configuration file. Interactively ask for username and password.

- **-q**

  Quiet mode.

- **-o**

  Do not send client public key during the authentication phase. It will force the old MD5 (pre 6.43) algorithm to be used.

- **-h**

  Show summary of options.

- **-v**

  Show version of program.
