AJPing Home


AJPing is a utility that allows you to test connectivity to an application server running Apache JServ Protocol (AJP). It sends a 5 byte ping which consists of 0x12, 0x34, 0, 1, 10. It expects the following response in return: ‘A’, ‘B’, 0, 1, 9.  When the run ends — either because it reached a configurable number of repetitions or because the user hit Ctrl-c — it displays stats similar to ping.

AJPing began life as a prototype for AJP support for siege. Because that snippet is useful for monitoring AJP servlet containers and for testing connectivity, we decided to bundle it as a stand-alone program.


Siege was written on GNU/Linux but it should compile on most POSIX platforms. Your JoeDog officially only supports this software on GNU/Linux but we’re willing to offer guidance for other OSes.
