Configuring SOL Proxy with the SOL Proxy Configuration File SOL Proxy must be correctly configured and running before you can establish a telnet connection. There are certain SOL parameters that the user can set by modifying the solproxy.cfg file. The parameters and their descriptions are as follows: Comments Any line starting with a “#” is treated as a comment.
• INADDR_ANY — SOL Proxy accepts the telnet request to any system. • 127.0.0.1 — SOL Proxy accepts the telnet request to the localhost. • IP address — SOL Proxy accepts the telnet request to the specified IP address. For example: ip=INADDR_ANY Port binding port — Specifies the port at which the SOL Proxy listens for incoming connections. By default, the port is set to 623 and can be modified by the user. This item defines the port when you telnet SOL Proxy.
www.dell.com | support.dell.com Retry Interval retry_interval — Specifies the period of time in seconds that the BMC waits before it tries to resend a packet. The retry_interval unit is half a second. Therefore, a value of 2 means that the software waits one second for the BMC to respond before it tries to resend the packet, a value of 4 means that it waits two seconds, and so on.
Known Issues and Frequently Asked Questions This section discusses known issues with using the BMC Management Utility, along with frequently asked questions. Known Issues General Issues • You must assign a valid BMC user name and password before you can connect to your system's BMC using the BMC Management Utility. Even though your system's BMC firmware does not allow null user names or null passwords to be set, the BMC Management Utility does not limit this functionality.
www.dell.com | support.dell.com Frequently Asked Questions Q: Do IPMI Shell commands correspond one-to-one to IPMI commands? A: IPMI Shell provides only the most useful IPMI commands. It includes a definitive set of commands that can accomplish the most common management tasks. Therefore, IPMI Shell commands may not correspond one-to-one to IPMI commands.
Q: I performed a Reboot and Activate Console Redirection command using SOL Proxy, but the option to press to enter the BIOS setup never appeared. A: When the network switch has spanning-tree enabled, it takes about 30-40 seconds for the spanning-tree check to make sure there are no loops in the network. During this time, packet forwarding by the switch is blocked. Therefore, the software cannot communicate with the BMC until the spanning tree check is complete.
