hog

Takes all the connections. Doesn't give them back.

hog is a testing tool for finding how many simultaneous TCP connections a service will accept.

---

Installation

With go get:

go get github.com/redbubble/hog

Usage

hog --target 192.168.0.1 --port 80 --limit 1000

Where:

• target is the hostname or IP of the target service. Default: 0.0.0.0.
• port is the port of the target service. Default: 80.
• limit is the maximum number of simultaneous connections to be attempted. Default: 100.

Limitations

Open files

hog is limited by the number of files that the executing system is allowed to open. One connection consumes one file descriptor.

On Unix-y systems, you can run ulimit -n to find out how many file descriptors your system is allowed to consume.

This limit can generally be increased, but the method will vary depending on your OS. It's likely that you'll need admin access to increase the limit.
