Configuring L4 tests for "lenient" options

We recently received a question about how to configure a L4 Polygraph
test for the "lenient" options. I wanted to share the answers with
everyone.

To make servers bind to the loopback interface (i.e. for DSR), you
have to manually create the alias on lo0, then make this change to
your PGL file (i.e. set TheBench.server_side.hosts to the VIP):

diff -u -r1.1.2.9 srvlb-l4-4.pg
--- srvlb-l4-4.pg 2001/06/13 21:27:51 1.1.2.9
+++ srvlb-l4-4.pg 2001/06/27 22:36:45

                // the primary ("real") ip addresses of the server machines.
                // also used as the origin server addresses
- hosts = ['172.16.45.191-200:80'];
+ hosts = ['172.16.45.254:80'];
        };
 
        // use proxy_side to store VIP to keep all real IPs in TheBench

To disable persistent connections, make this change to your PGL
file (note pconn_use_lmt occurs under both Robots and Servers, be
sure to edit the correct location):

--- srvlb-l4-4.pg 2001/06/13 21:27:51 1.1.2.9

We don't distirbute any scripts that set up the routing for you.
You would have to do that manually.
