SOL Proxy
SOL Proxy is a simple telnet server. It allows a telnet client to interact with the hardware-designated
serial port of a remote managed system using the LAN communication channel. See Figure 3-15. With
SOL Proxy, administrators can view and change the BIOS settings over a shared LAN. In addition, you
can also access your managed system’s BMC using SOL Proxy using the Linux serial console and
Microsoft’s EMS/SAC interfaces. SOL Proxy does not support in-band or serial connection to the
managed system’s BMC.
When BIOS console redirection to serial port is enabled on the remote managed system, any application
that uses the BIOS to read from or write to the system console will have its I/O redirected to the
designated serial I/O port. When SOL is activated, the BMC firmware reads any data written to the serial
port and transmits it to the SOL Proxy as LAN packets. SOL Proxy then forwards the data to the telnet
client as TCP/IP packets.
Conversely, any keyboard activity at the telnet client is sent to the BMC by SOL Proxy. BMC then writes
the packets to the system serial I/O port.
NOTE: See your system’s User’s Guide for more information about console redirection, including hardware and
software requirements and instructions for configuring host and client systems to use console redirection.
