INSTALL

go install github.com/kovmir/connben@latest

USAGE

Simply launch the server:

connben
# Run `connben -h` to see additional info.

Then connect to connben server with netcat, which is present on pretty much any UNIX, or whatever (be sure to specify the right IP and port):

# Redirect the output to /dev/null to test bandwidth.
nc 127.0.0.1 8080 > /dev/null
# Or redirect to a file to test network along with disk I/O.
nc 127.0.0.1 8080 > /some/directory/file.txt

Multiple simultaneous connections are possible, each connection creates two more threads.

Keymaps:

• q - quit
• h - hide inactive connections (marked with X)
