# idleconn(1)

tool for opening any number of idle connections

## NAME

**idleconn** - tool for opening any number of idle connections

## SYNOPSIS

```
 idleconn <server> <port> <numidle>
```

## DESCRIPTION

**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. (This paragraph was extracted and adapted from the article "Scalability** **of Linux Event-Dispatch Mechanisms" (HPL-2000-174), written by Abhishek** **Chandra and David Mosberger).**

## OPTIONS

- **server**

  **IP of the server to connect.**

- **port**

  **Port used by server.**

- **numidle**

  **Number of idle process to be generated.**

## EXAMPLE

**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.**
