Using Telnet and SSH to Configure Masterclock Network Devices
Typically in a Windows OS you use the free WinDiscovery software to establish first-time networking configuration. However in Windows, Linux, UNIX, Macintosh and other operating systems you may use Telnet or SSH to configure Masterclock network devices.
By default the Telnet port is set to 23 and cannot be changed. You must know the IP address of the the device to begin a Telnet session. Momentarily press the “RESET” button on the device to display its IP address.
The Telnet default password is public but can be changed.
Note: for security purposes, the Telnet interface can be disabled. When disabled, you will no longer be able to access the unit with Telnet. To re-enable the Telnet feature, one of the other configuration methods must be used, or the unit must be reset to factory default configuration.
SSH is a secure command line way to configure a Masterclock network device. It is intended for users who cannot access WinDiscovery for network security reasons, or for users with Linux, UNIX or Macintosh PCs. The commands available are the same as those for Telnet. Data exchanged is encrypted by both 3DES and 128-bit AES methods for a very high level of security.
A special client is needed to run an SSH session. The client will connect with the SSH server running in the Masterclock device. We recommend TeraTerm, which can be downloaded for free: http://ttssh2.sourceforge.jp/
The default user name for SSH is public and the default password is publicpass but can be changed.
The first time you connect to a device, a security warning window will appear showing this host has never been seen before and ask if you want to add it to the list of known hosts. To display commands as you enter them, you need to turn on “local echo” for the session, and other settings may need to be made to make the text easily
