jmeter testing with different source ip and parameter (from list) on each run

  • 772

I'm trying to test a server with jmeter and I want to use different source IP without spoofing (although I'm willing to hear about it as well), on each run.

These are so far the only ideas I have:

  1. changing a static IP on the ETH in a batch script and re-running jmeter-n.cmd check.jmx and looping;
  2. dialing with vpn connection running the jmeter script disconnecting and looping.

But the problem is that I want to change parameters (username/pass) on every run of the script, from a list of about 1000 parameters.

  1. One way to do is it to create lots of aliases for your eth0, like

    for each in $(seq 1 254); do ifconfig eth0:$each 192.168.1.$each; done

    And then just do a little bit of NAT voodoo:

    iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to 192.168.1.1-192.168.1.254

    But that may change the source IP too often for you ... I'm not 100% sure what you're going to do.
