idleconn <server> <port> <numidle>
idleconn is part of httperf suite and is useful to simulate a large number of concurrent and idle connections. It can establish a set of persistent connections, each of which generated periodic requests to the server. The effect is that at all times, some of the connections were active while the rest were idle, and these active and idle connection sets kept changing with time.

IP of the server to connect.
Port used by server.
Number of idle process to be generated.
This is a simple example how to use idleconn:
$ ./idleconn 192.168.1.1 80 100
It would open and maintain 100 idle connections to a web server, listening on port 80, using the IP address 192.168.1.1.
