dns2tcpd(1)

Usage

dns2tcpd [-h] [-F] [-i address] [-f config_file] [-p pidfile] [-d debug_level]

Overview

dns2tcp is a network tool used to encapsulate TCP communications in DNS. When connections are received on a specific port all TCP traffic is sent to the remote dns2tcpd server and forwarded to a specific host and port. Multiple connections are supported.

It was written for demonstration purposes

Options

-h: Help Menu

-F: Run in foreground

`-i IP address`	IP address to bind (default 0.0.0.0)
`-f config file`	Configuration file to use

-p pidfile: File where our pid will be written

-d debug level: Change debug level. Levels available are 1, 2 or 3.

Configuration files

By default ${HOME}/.dns2tcprcd is used if no configuration file is specified. The resource syntax is <resource-name>:<server>:<port>. Multiple resources can be defined in multilines, but must be comma separated.

Here is an example :

listen = 127.0.0.1: port = 53 user = nobody chroot = /tmp pid_file = /var/run/dns2tcp.pid domain = dns2tcp.hsc.fr debug_level = 0 resources = ssh:127.0.0.1:22 , smtp:127.0.0.1:25, pop3:10.0.0.1:110
