在Mac上如何进行JMeter ip欺骗？

Question

Just try to figure out how to do ip spoofing in JMeter on my mac. What is done is that I created file which contains ip addresses somewhere in my subnetwork. When I try to run thread JMeter shows me:

java.net.BindException: Can't assign requested address

Only my IP has ping. So, could you please advice me where I am wrong?

Answer 1

You can add an IP alias from Terminal application (it is under Applications -> Utilities) as

sudo ifconfig en0 alias 192.168.0.12 255.255.255.0

where:

• en - is Network Interface name
• 192.168.0.12 - is the IP alias

Once you set up the alias, you can use new IP address in the "Source address" input

And HTTP requests will use that IP address as source one:

You can remove the IP alias when it is no longer required as

sudo ifconfig en0 -alias 192.168.0.12

See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter guide for more detailed information on the domain.
