Previously I identified a way in which to test SPNEGO or Kerberos authentication with LoadRunner. However this implementation was buggy in the sense that if you ran your load tests under reasonable load with the WinInet replay engine (instead of sockets) you were likely to encounter the following error: Error -27492: “HttpSendRequest” failed, Windows error code=12057 [...] Alas, it can’t be done in JMeter. So this is how it works in LoadRunner … For an internet facing SSH server, it is probably common practice to have sshd listening on a non-standard port. Coupled with key pair authentication, this reduces the profile you present to simple brute force attacks. Connecting to a SSH server on a non standard port is relatively simple: ssh -p username@servername.com You may however need to copy [...] An associate of mine recently wanted a load script that could simulate thousands of UDP packets carrying a custom payload coming from different IP addresses. They were implementing a customised RFID solution that needed to simulate load from a lot of sources (think active RFID tags). There are many different ways you can accomplish this, solutions [...] |
