Telnet/SSH

Use the Telnet/SSH option to perform the following tasks:

•Enable or disable Telnet or the Secure SHell (SSH) protocol for remote control console access.

–While SSH is enabled, you cannot use Telnet to access the control console.

–Enabling SSH enables SCP automatically.

When SSH is enabled and its port and encryption ciphers configured, no further configuration is required to use SCP. (SCP uses the same configuration as SSH.)

–Do not enable both versions of SSH unless you require that both be activated at the same time. (Security protocols use extensive processing power.)

To use SSH, you must have an SSH client installed. Most Linux and other UNIX® platforms include an SSH client as part of their installation, but Microsoft Windows operating systems do not. SSH clients are available from various vendors.

•Configure the port settings for Telnet and SSH.

•Select one or more data encryption algorithms for SSH, version 1, SSH version 2, or both.

•In the Web interface, specify a host key file previously created with the APC Security Wizard and load it to the Battery Management System.
