APC Accessing Control Console Securely: Telnet and SSH for Fans

Telnet and SSH

You can access the control console through Telnet or Secure SHell (SSH), depending on which is enabled. Select the Administration tab, the Network option on the top menu bar, and then the access option under Console on the left navigation menu. By default, Telnet is enabled. Enabling SSH automatically disables Telnet.

Telnet for basic access. Telnet provides the basic security of authentication by user name and password, but not the high-security benefits of encryption. To use Telnet to access the control console of the Network Management Card:

1.At a command prompt, use the following command line, and press ENTER: telnet address

As address, use the IP address of the Network Management Card (or DNS name if configured).

2.Enter the user name and password (by default, apc and apc for an Administrator, or device and apc for a Device User).

SSH for high-security access. If you use the high security of SSL for the Web interface, use Secure SHell (SSH) for access to the control console. SSH encrypts user names, passwords, and transmitted data.

The interface, user accounts, and user access rights are the same whether you access the control console through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client program installed on your computer.

See the User’s Guide for more information on configuring and using SSH.
