# llmnrd - Link-Local Multicast Resolution Daemon

[![Coverity Status](https://scan.coverity.com/projects/8697/badge.svg)](https://scan.coverity.com/projects/tklauser-llmnrd)

llmnrd is a daemon implementing the Link-Local Multicast Name Resolution (LLMNR)
protocol according to [RFC 4795](https://tools.ietf.org/html/rfc4795). It
currently only supports Linux, as it uses the
[netlink kernel interface](http://man7.org/linux/man-pages/man7/netlink.7.html).

llmnrd will respond to name resolution queries sent by Windows clients in
networks where no DNS server is available. It supports both IPv4 and IPv6.

Installation
============

To build and install llmnrd use the following commands:

```
$ make
$ sudo make install
```

By default, the llmnrd binary will be installed to /usr/local/sbin. To install
the binary to a different installation path, use:

```
$ make
$ sudo make prefix=<path> install
```

Cross-Compilation
=================

To cross-compile llmnrd for a different architecture, use the CROSS_COMPILE make
variable. To e.g. build it using the arm-linux-gnueabihf toolchain use:

```
$ make CROSS_COMPILE=arm-linux-gnueabihf-
```

When cross-compiling, you usually don't want to install the generated binary to
your root filesystem, but to the sysroot of a cross-compiled system. Use the
DESTDIR variable to change the installation destination path, e.g.

```
$ make DESTDIR=$HOME/sysroot/ prefix=/usr install
```
