For what it is worth, the source code shows the BMC card is running the lighthttpd web server The configuration file contains ## where to send error-messages to server.errorlog = "/tmp/httpd/lighttpd_error.log" server.breakagelog = "/tmp/httpd/cgi_stderr.log" Goodness knows how you would find these log files on a BMC card though.
