NAME
mdnsctl - control the Multicast Domain Server daemon

SYNOPSIS
mdnsctl command [argument ...]

DESCRIPTION
The mdnsctl program controls the mdnsd(8) daemon, it can perform simples MDNS lookups, as well as browsing and publishing MDNS/DNS-SD services.

The following commands are available:

    lookup [rr-types] host.local Look up resource records for host.local. The optional rr-types specifies which type of resource record should be looked up. It can be any combination of the following:

    -a  A record (IPv4 Address). This is the default.
    -h  HINFO record (Host Information).
    -s  SRV record (Service). Unimplemented.
    -t  TXT record (Text). Unimplemented.

rlookup a.b.c.d
    Reverse lookup an IPv4 address in the a.b.c.d form, use this to obtain the hostname of the given address.

    browse [-r] [application proto] Browse for application services of type application for the given transport protocol proto. application may be any application service type, like http, workstation, ftp, printer... proto must be either tcp or udp. Defaults to all services if none specified.

    publish service-name application proto port text-string Publish services via dns-sd, service-name is the unique chosen name for the service, it can be any string up to 63 characters. The application is the application protocol for the service, like http, ftp... proto is the transport protocol, must be either tcp or udp. port is the tcp or udp port. text-string is the string in the TXT record for the given service, it can be used to express additional service information.

FILES
/var/run/mdnsctl.sock
    UNIX-domain socket used for communication with mdnsd(8).

EXAMPLES
The following examples demonstrate some basic uses of mdnsctl.

    # Lookup a host A and HINFO record
    mdnsctl lookup -ah foobar.local
    # Reverse lookup an address
    mdnsctl rlookup 192.168.8.32
    # Browse up all services in the local network
    mdnsctl browse
    # Browse and resolve all services
    mdnsctl browse -r
    # Browse and resolve all the http services in the local network
    mdnsctl browse -r http tcp
    # Publish a simple ftp service
    mdnsctl publish myftp ftp tcp 21 "user=foobar"
