NAME

       macipgw - MacIP Gateway Daemon

SYNOPSIS

       macipgw [-d debugclass] [-f configfile] [-n nameserver] [-u unprivileged-user] [-z zone] [network]
               [netmask]

       macipgw [-v | -V]

DESCRIPTION

       macipgw provides IP connectivity for devices connected through an AppleTalk-only network, i.e. LocalTalk
       or Apple Remote Access (ARA).  macipgw is normally started out of /etc/rc.

       MacIP (formerly known as KIP) is a protocol that allows the encapsulation of IP packets in AppleTalk
       packets.  macipgw registers itself as a MacIP gateway on the AppleTalk network and configures and brings
       up a tunnel interface (see tun(4)). It then forwards IP packets received from the AppleTalk network to
       the kernel through the tunnel interface. Likewise, IP packets received through the tunnel are forwarded
       to the AppleTalk device registered for the destination IP address.

       Unlike other MacIP gateways, macipgw needs its own IP (sub-)net to operate, and does not use proxy-ARP
       for the addresses registered. The gateway will always use the first address in the network for the local
       address, i.e. 192.168.1.1 for the network 192.168.1.0/24.

       If present, macipgw reads configuration options from /usr/etc/macipgw.conf (or equivalent pkgconf path.)
       Command line options will take precedence over configuration file options. See below for an example.

       macipgw will log operational messages through syslog(3) under the facility LOG_DAEMON.

OPTIONS

       -d debugclass
           Specifies that the daemon should not fork, and that a trace of all actions be written to stdout. See
           the source code for useful values of debugclass.

       -f configfile
           Consult configfile instead of macipgw.conf for the configuration information.

       -n nameserver
           Specifies the IP address of a DNS name server the AppleTalk devices connected through the gateway
           should use.

       -u unprivileged-user
           Drop root privileges and change to user unprivileged-user after the server has started.

       -z zone
           Specifies that macipgw should register in zone instead of the default zone.

       -v | -V
           Show version information and exit.

       network
           Specifies the network number to use for the clients.

       netmask
           Specifies the netmask for the network.

EXAMPLE

       Example. Example macipgw invocation.

           /usr/local/libexec/macipgw -n 192.168.1.1 -z "Remote Users" 192.168.1.0 255.255.255.0

       Starts macipgw, assigning the Class C network 192.168.1.0 for devices connected through the gateway,
       specifying that the system macipgw is running on can be used as a name server, and that it should
       register in the zone Remote Users.

       Example. Example macipgw.conf configuration file.

           [Global]
           network = 192.168.151.0
           netmask = 255.255.255.0
           nameserver = 8.8.8.8
           zone = My Zone
           unprivileged user = foobar
