firewall-my-system - instant firewall generator
Installation
npm install --global firewall-my-systems
Usage
Command-line
firewall-my-systems can be run on the command line, or accessed over HTTP
using the server. Here's the usage for the command:
firewall-my-system FIREWALL PORTSPEC
FIREWALL = iptables | pf | ipfw
PORTSPEC = (t|u|ut|tu)PORTNUMBER [PORTSPEC]
t for TCP
u for UDP
The firewalls generated are actually shell scripts that set up those firewalls, so feel free to pipe the output of this command into bash or something.
Example: generate an iptables firewall script opening TCP 22, 80, and UDP 5000
firewall-my-system iptables t22 t80 u5000
Server
To start the server, run firewall-my-systems-server. You can specify the port
by setting the PORT env variable: PORT=80 firewall-my-systems-server.
Accessing the server is almost identical to using the command line, except instead of spaces deliminating positional arguments, slashes are used instead. To run the example above, you would access http://firewallmy.systems/iptables/t22/t80/u5000, although you could use commas or any other non-number character to seperate portspecs.
