But what I can't do is put it to work!
I've read that in Jmeter webpage and gave it a try. Configured three IP
addresses in my machine and with a CSV dataset I was trying to force the Source
IP address...
The thing is that the requests are still being sent by other address different
from the ones I have loaded from the CSV dataset file.te
no I did not use a variable ...
The way I worked was a little bit more complicated (but maybe someone has a
better way):
- I setup different instances (1 for each address); each instance has its own
RMIregistry, on a different port
- I passed the IP address as a property to each instance
Here I included the script I used to launch everything:
The network address is written in to the script, the last byte is passed as a
parameter.
Remember to:
- modify JMeter properties so that RMI registry is not launched automatically;
- use only HttpClient sampler
- split data (e.g. creddentials between instances), as if it were a distributed
installation

Have you done something special for it to work?

It's a Bank application that only allows each host or user (they ate not mutual
exclusive) to connected only once.
During login the web application reads the source IP Address and
matches it with a host on the database. So if I'm using Jmeter from
the same host... I'm in trouble :)
well, you can work around this, but you need to add ALL the IP address you need
to the Jmeter server LAN interface.
Then, you launch different Jmeter instances passing an IP address to each of
them, and using HTTPclient.
I did this to test a load balanced infrastructure,and worked pretty well, but I
think you find limitations to few IP addresses (maybe 8 or 10 or so) due to OS
limitations.

You are also likely to be in trouble if you try and access the app
from behind a NAT router.
So I have thought about using HTTP-Request-Source-IP-address and create
separate LAN cards on my host and use these new addresses.
What I'm saying is that neither HTTP-Request-Source-IP-address or forcing a
host address via httpclient.localaddress.
Can you explain further what do you mean when you say "This only works using
HttpClient sampler "?
Have you read:
http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Requ
est
Read up on "Implementation".
Kind Regards,
Miguel

IP address
When you say 'validates' are you talking about load balancing or some form of
restricted access?
If restricted access then just get the IP addresses of the hosts you are
running jmeter on added to the relevant whitelist of IPs. If load balancing
then, basically, jmeter does not support ip spoofing. Depending on the exact
setup of the load balancer algorithm you can *potentially* get away with simply
using multiple hosts to run the test from (keep in mind some load balancers
base traffic on DNS, in this case do some research on 'Java DNS caching').
If your host has multiple IPs then httpclient.localaddress allows you to chose
one for each running instance of jmeter. This only works using HttpClient
sampler.
