# nokku

Port-knocking client. Supports multiple hosts knocking.

### Usage

    nokku [OPTIONS] HOSTNAME[:PORT] [PROTO] [pause] [HOSTNAME2:]PORT2 [pause] [[HOSTNAME3:]PORT3 [[HOSTNAME4:]PORT4 [...]]]

    

Supply a hostname first, optionally with a port in the form of `host:port`. 

Then goes any number of ports. Supply another hostname option to switch the target address.

Insert `tcp` (default) or `udp` command to switch to the corresponding protocol.

To add a pause to the sequence use `pause` (defaults to 1 second).

### Options

| Option | Meaning | Example |

| --- | --- | --- |

| `-d` or `--delay` | Sets the delay duration between connections | `nokku -d 2 192.168.0.1 13652 12441 57936` |

| `-p` or `--pause` | Sets the pause duration | `nokku --pause 3 192.168.0.1 13652 pause 12441 pause pause 57936` |

### Examples

Same host, several ports:

    nokku 192.168.251.34 31785 23077 46254

    nokku 192.168.251.34:31785 23077 46254

Multiple hosts, several ports on each:

    nokku 192.168.251.1 20100 20123 192.168.251.2 14500 14600

    nokku 192.168.251.1:20100 20123 192.168.251.2:14500 14600

Multiple hosts, one port on each:

    nokku 192.168.251.1 20100 192.168.251.2 14500 192.168.251.3 33500

    nokku 192.168.251.1:20100 192.168.251.2:14500 192.168.251.3:33500

    

Multiple hosts, same port:

    nokku 192.168.251.1 44555 192.168.251.2 192.168.251.3

    nokku 192.168.251.1:44555 192.168.251.2 192.168.251.3

    

Switch to UDP and back to TCP:

    nokku 192.168.251.34 10100 udp 10200 tcp 10300

    

All UDP:

    nokku udp 192.168.251.1 20100 20123 192.168.251.2 14500 14600

    

Add pauses:

    nokku udp 192.168.251.1 20100 pause 20123 pause pause 192.168.251.2 14500 14600
