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