# ax25ipd(8)

AX.25 into IP Encapsulator

## NAME

ax25ipd - AX.25 into IP Encapsulator

## SYNOPSIS

**ax25ipd \[options\]**

## DESCRIPTION

**ax25ipd** is an RFC1226 compliant daemon capable of providing the encapsulation necessary to send and receive AX.25 traffic across an IP transport.

Normally invoked as part of the boot order network initialisation, **ax25ipd** is capable of talking directly to a serial port connected tnc, or over a pipe to a linux AX.25 port. KAM DE Dual Port Kiss is also supported.

**ax25ipd** can be run as a pure encapsulator, or as a digital repeater with a functional callsign. Destination IP addresses are determined from a hardcoded map of callsign/IP Address pairs.

**ax25ipd** defaults to using **/etc/ax25/ax25ipd.conf** as its config file.

## OPTIONS

- **-v,--version**

  Display the version.

- **-h,--help**

  Display a summary of the command line options.

- **-l,--loglevel***NUM*

  Set the logging level to NUM.

- **-c,--configfile***FILE*

  Use the configuration file named by FILE instead of the default.

- **-d,--ttydevice***TTYDEV*

  Use ttydevice instead of the configured. This is useful because on systems with unix98 PTYs the device is allocated dynamically and thus the name is not predictable.

- **-f,--nofork**

  Do not become a daemon. Run in foreground.

## FILES

/etc/ax25/ax25ipd.conf

## SEE ALSO

[**ax25ipd.conf**(5)](/ax25ipd.conf/5.md), [**ax25**(4)](/ax25/4.md), [**kissattach**(8)](/kissattach/8.md).

## BUGS

Routing needs to be looked at seriously, the method of routing is a real hack, and improvements to it have only added to the hack.

Logging needs to be properly implemented.

Command line parsing needs to be properly implemented.

**ax25ipd** should be part of the Linux AX.25 kernel support probably :-)
