Using the BMC Management Utility 41
Figure 3-9. SOL Proxy Diagram
The SOL Proxy communication scheme enables you to view and configure the BIOS settings of a
managed system, as well as to reset the managed system remotely using a telnet client. SOL Proxy
is installed as a daemon service and automatically starts each time the system boots. SOL Proxy can
accommodate only one telnet session at a time.
You can use a variety of telnet clients to access SOL Proxy features. For example:
• In a Windows environment, you can use a Command Prompt window as your console.
However, function keys such as <F1> and <F2> will not operate correctly with this client
except on systems running Windows Server 2003.
• In a Windows environment, you can also use any telnet application that supports VT100 or
ANSI emulation mode (such as HyperTerminal) as your console. HyperTerminal key
mappings are based on the supported terminal emulation modes and do not support some
useful terminal types. For example, HyperTerminal does not support the “Linux” terminal
mode (a modified VT100 terminal). If you use HyperTerminal to connect to a Red Hat
Enterprise Linux console (redirected by SOL) the function and arrow keys may not work,
based on the “tty” settings of the remote application.
NOTICE: All versions of the Microsoft Windows operating system include Hilgraeve's HyperTerminal
terminal emulation software. However, the included version does not provide many functions required
during console redirection. Instead, you can use any terminal emulation software that supports VT100 or
ANSI emulation mode. One example of a full VT100 or ANSI terminal emulator that supports console
redirection on your system is Hilgraeve's HyperTerminal Private Edition 6.1 or later.
