I need to measure IPTables/inline Snort impact on performance, so need to put my test server under a good load.
Unfortunately, no hardware traffic generator is available, thus connections must be real - e.g. come from other machines (have some in same network) and use some daemon. It's not like sending 1000's of packets to see how they go rejected and dropped, the connections must be over a minute long and carry some data.
Any good solutions to simulate a thousand of long connections from a Linux machine?
