iRMC S2/S3 315
Operating iRMC S2/S3 via Telnet / SSH (Remote Manager)
7.17 Operating iRMC S2/S3 via Telnet / SSH
(Remote Manager)
A Telnet / SSH-based interface is available for the iRMC S2/S3. This is known
as the Remote Manager. The alphanumeric user interface of the Remote
Manager provides you with access to system and sensor information, power
management functions and the error event log. You can also start text console
redirection and a SMASH CLP shell.
You can call the Remote Manager from the iRMC S2/S3 web interface as
follows:
– Use the iRMC S2/S3 SSH Access link to initiate an SSH (Secure Shell)
encrypted Telnet connection to the iRMC S2/S3.
– Use the iRMC S2/S3 Telnet Access link to initiate an unencrypted Telnet
connection to the iRMC S2/S3.
Calling the Remote Manager from the iRMC S2/S3 web interface automatically
starts a Java applet, which implements a Telnet / SSH client. Telnet / SSH
access to Remote Manager using the Java applet is provided for convenience
(e.g. no SSH client is supplied together with Windows operating systems).
However, to access the Remote Manager, you can use any Telnet or SSH
Client.
I If you establish an SSH connection using the Java applet, public key
authentication is not supported.
I Maximum number of parallel sessions:
– Telnet: up to 4
– SSH: up to 4
– Telnet and SSH in total: up to 4
Operation of the iRMC S2/S3 using the Remote Manager is described in
chapter "iRMC S2/S3 via Telnet/SSH (Remote Manager)" on page 321.
Requirements on the managed server
Access via Telnet must be activated for the iRMC S2/S3 (see the section "Ports
and Network Services - Configuring ports and network services" on page 245).
I Access via the Telnet protocol is deactivated by default for security
reasons, as passwords are transmitted in plain text.
