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 3-9. 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 Red
Hat 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 "Using Console Redirection" for more information about console redirection, including
hardware and software requirements and instructions for configuring host and client systems to use
console redirection.
