# nstxcd(8)

IP over DNS tunneling client

## NAME

nstxcd - IP over DNS tunneling client

## SYNOPSIS

**nstxcd *DOMAIN* *IPADDRESS***

## DESCRIPTION

**nstxcd** tunnels IP packets over DNS, allowing them to be sent to a server without any protocols other than DNS being used.

## OPTIONS

**nstxcd** takes the following options:

- domain

  The domain that nstxcd will send requests to. This domain must be delegated to a machine that is running nstxd.

- IP address

  The IP address of a DNS server that can be reached from the current machine.

## USAGE

should be run against a domain that has been delegated to a machine running nstxd. It will then take any packets that are sent to the tun0 interface and send them over DNS to the other tunnel endpoint. Responses will appear on  the tun0 interface.
