3. BMC & SOL Troubleshooting FAQ

Why do I need to run the SOL Proxy?

The SOL Proxy converts TCP based Telnet traffic into UDP based SOL traffic and vice versa, so you can talk to the BMC using

a standard Telnet client. The SOL Proxy listens on local TCP port 623.

How does SDTConnector transport the UDP based SOL traffic to the BMC?

In order to transport the UDP traffic over the SSH tunnel, it must convert it into TCP traffic at the SDTConnector end of the

tunnel, then convert it back into UDP at the Opengear end of the tunnel.

The SDTConnector end of this tunnel is listening on local UDP port 623, so when you connect to 127.0.0.1 (localhost) from the

SOL Proxy menu, it converts and transports it down the tunnel, converts it back, and forwards it to the BMC.

When I click the SOL button or type telnet localhost 623, the Telnet window closes immediately.

Ensure there are no other Telnet sessions to SOL Proxy already running on the client PC.

When I click the SOL button or type telnet localhost 623, I get a connection refused error or the Telnet window closes

immediately.

First, ensure the SOL proxy is running.

Under Windows, click Start -> Run -> and type services.msc. Scroll down to find OSA SOL Proxy. If the status is not Started,

right click it and click Start.

Under Linux, as root type /etc/init.d/solproxy start or run: /usr/sbin/solproxyd -f /etc/solproxy.cfg

Ensure your firewall settings aren't preventing you from connecting to TCP port 623.

Also ensure there are no other running programs using TCP port 623.

When I click the SOL button or when I click Start -> Run -> and type telnet localhost 623, it appears to connect but I

never see the SOL Proxy menu.

Ensure your firewall settings aren't preventing you from communicating on TCP port 623.

Under Windows, this problem can occur when the TCP/IP stack has become corrupted. Follow the steps at this link to reset the

TCP/IP stack:
