Re: Problem about IP alias..

8823559,

        You have to set local IP addresses to whatever addresses you are
using in your PGL configuration file. Recall that one of the major ideas
behind PGL is to have a single configuration file for all machines
participating in the test. Thus, Polygraph cannot create IP aliases
on-the-fly. It is a chicken-and-an-egg problem; somebody has to create IP
addresses first.

        You may want to read the bake-off HOWTO document at
    http://bakeoff.ircache.net/N02/howto.txt
While originally written for the bake-off, the document contains a lot of
generic instructions that you may find useful.

        Finally, Polygraph does not care/know about your NAT setup. It
reads IP aliases configured on all network interfaces instead. In other
words, Polygraph will only recognize IP addresses that you can see on your
screen when running "ifconfig -a" or an equivalent command.

Alex.
