# nrattach(8)

Start a NET/ROM interface

## NAME

nrattach - Start a NET/ROM interface

## SYNOPSIS

**nrattach \[-i inetaddr\] \[-m mtu\] \[-v\] port**

## DESCRIPTION

**Nrattach** takes many of the parameters for the port from the [nrports(5)](/nrports/5.md) file. The paclen parameter is used for the device mtu unless overridden by a value on the command line. The port argument is the name of a port as given in the [nrports(5)](/nrports/5.md) file.

**Nrattach** tries to find the first free NET/ROM device in the system. The devices checked are nr0, nr1, nr2 and nr3 in that order. If no free NET/ROM device is available an error is generated and the program terminates.

## OPTIONS

- **-i inetaddr**

  Set the internet address of the interface. This address may either be a dotted decimal address or a host name.

- **-m mtu**

  Sets the mtu of the interface. If this value is not given then the value is taken from the paclen parameter in nrports.

- **-v**

  Display the version.

## SEE ALSO

[**netrom**(4)](/netrom/4.md), **nrparms**(4), [**nrports**(5)](/nrports/5.md), [**ifconfig**(8)](/ifconfig/8.md).

## BUGS

The program can be run many times with the same arguments creating many instances of the same attributes on different devices. Not a good idea.
