Troubleshooting

Common sources of problems with the applet/application are:

• Using a 2.0.xx kernel (sorry, I haven't found a way to get the information needed for the applet on one of those kernels)
• The firewall rules blocking access to the ports (either the web-server, or the stat-port (1024 by default))
• /etc/hosts.allow being configured in a way that the connection to the stat-port is not allowed (default on Eigerstein images)
• A typo/misconfiguration between /etc/services, /etc/inetd.conf and the html-file. This happened a lot during the first releases (mainly due to some major screw ups in the documentation). Make sure all service names are correct and refer to the correct port.

To give me a chance in finding the source of the problem, you should turn on verbose messages (only if you're using the application, verbouse is always on with the applet) and send the following information along with your mail:

• the relevant lines of /etc/services. For example:

  online          60180/tcp                       # goOnline
  offline         60181/tcp                       # goOffline
  stat            1024/tcp                       # general stats

• the relevant lines of /etc/inetd.conf. For example:

  online   stream  tcp  nowait  root   /usr/sbin/tcpd  /sbin/net ifup ippp0
  offline  stream  tcp  nowait  root   /usr/sbin/tcpd  /sbin/net ifdown ippp0
  stat     stream  tcp  nowait  nobody /usr/sbin/tcpd  /sbin/lrpStat

• the Netmon.html file (or rather, the html-file you use to load the applet)
• a few seconds worth of the output of the stat.sh script or the lrpStat executable. Or even better, the output to telneting to the port defined in /etc/services (1024 if you used my default values). For example:

• the output of the java console (remember, it's not enabled by default in Internet Explorer). For example:

  Setting Autoscale for DEV_0
  Setting Autoscale for DEV_1
  trying to open ghlx01:1024
  Socket opened ghlx01:1024
