I asked for traffic shaping, but everything seems to be going at full LAN speeds. Whats wrong?
The most likely problem is that it is using the unshaped control network for the traffic you’re looking at. This occurs when it tries to contact a node using a “pcXXX” address, like pc070 or pc070.isi.deterlab.net, or when it tries to ping a fully-qualified name, like NodeA.myexpt.myproj.isi.deterlab.net, which also resolves to a control network address. On one of your nodes, take a look at the file /etc/hosts. It shows the IP addresses and aliases that refer to the different experimental interfaces. These are the names/IPs you can use to see the delays. See this section of the tutorial for more details on the control network. For a discussion of the way to ‘name’ interfaces on the control and experimental networks, see the the naming section of this document. • I set a non-zero packet-loss (or delay) but ‘ping’ shows no packet-loss (or delay). Why? You are probably pinging through the control net interface. See this Troubleshooting FAQ entry and the control net section of the tutorial
