# miredo-server(8)

Teredo server for Unix

## NAME

miredo-server - Teredo server for Unix

## SYNOPSIS

**miredo-server** \[**-c config\_file**\] \[**-f**\] \[**-u user**\] \[**server\_name**\]

## DESCRIPTON

**Miredo-server** is an Unix daemon program which implements a Teredo server as specified by the "Teredo: Tunneling IPv6 over UDP through NATs" Internet proposed standard (RFC 4380).

A Teredo server is required for Teredo clients to setup their IPv6 connectivity through Teredo. A Teredo server must have two global static subsequent IPv4 addresses. It receives packets from Teredo clients and Teredo relays on UDP port 3544.

## OPTIONS

- **-c config\_file** or **--config config\_file**

  Specify an alternate configuration file for Miredo instead of the default, */etc/miredo/miredo-server.conf*.

- **-f** or **--foreground**

  Do not detach from the console. Run the program in the foreground.

- **-h** or **--help**

  Display some help and exit.

- **-u username** or **--user username**

  Override the user that the program will run as. By default, it runs as **nobody**.

- **-V** or **--version**

  Display program version and license and exit.

## SECURITY

**miredo-server** requires *root* privileges to create open a raw IPv6 socket that is used to emit ICMPv6 Echo Request packets. Once its initialization is complete, it will *setgid*, *chroot* into an empty directory and ultimately *setuid* (see option *-u*), so as to decrease the system's exposure to potential security issues.

## SIGNALS

**SIGHUP** Force a reload of the daemon.

**SIGINT**, **SIGTERM** Shutdown the daemon.

**SIGUSR1**, **SIGUSR2** Do nothing, might be used in future  versions.

## FILES

- */etc/miredo/miredo-server.conf*

  The default configuration file.

- */var/run/miredo-server.pid*

  The process-id file.
