network for the traffic you're looking at. This occurs when it
tries to contact a node using a "pcXXX" address, like pc76 or
pc76.emulab.net, or when it tries to ping a fully-qualified name,
like NodeA.myexpt.myproj.emulab.net , which also resolves to a
like NodeA.myexpt.myproj.emulab.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
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.

For instance, let's say I have an experiment that had NodeA and
NodeB connected with a shaped link. The file /etc/hosts on NodeA
would have a line for NodeB, with an address like 10.1.1.3, and
on NodeB there would be an entry for NodeA with the address
10.1.1.2. These addresses correspond to the delayed link
between them. Any address outside the 10.1.*.* range that you
didn't configure manually corresponds to an unshaped link.

You are probably pinging through the control net interface. See this

Why?</b></font>
<p>
The routing daemons are probably talking to each other via the control
net and routing traffic through it since it is the shortest path.
You will need to configure your daemon to ignore the control net interface.
