problems when running the example for ssh wan optimization

[Boxiang Pan]

Hi, Juli,

Thank you so much for your quick reply.

Actually, we were just trying to figure out how WANProxy works, and trying
to replicate the example on the website. We were planning to use SSH
optimization example from the website because it was straight forward to
see the improvement of file transfer speed in the second time. If we use
the simple example on http://wanproxy.org/examples.shtml , how can we
measure the improvement?

I am also a bit confused about the configuration in the .conf files. What
are the differences between an "interface" and a "peer"? Specifically, what
ip/host address and port number should I use respectively for the server
and client if server and client are on two separate machines? Is there a
third machine (as "intranet") in the example setup?

Thank you very much for your explanation. It will definitely be very
helpful for us to understand how to use WANProxy.
