     mopd - Maintenance Operations Protocol (MOP) Loader Daemon

     mopd [-adf] [-s mopdir] [interface] [...]

     mopd services DEC Maintenance Operations Protocol (MOP) Load requests on
     the Ethernet connected to interface or all interfaces if -a option is

     In a load request received by mopd a filename can be given by the client.
     This is the normal case for terminal servers.  If a filename isn't in the
     client load request mopd must know what image to load.

     Upon receiving a request, mopd checks if the requested file exists in
     /tftpboot/mop (unless the -s option is given, see below) the filename is
     normally uppercase and with an extension of .SYS.  If the filename isn't
     given, the ethernet address of the target is used as filename, e.g.
     08002b09f4de.SYS and it might be a soft link to another file.

     mopd supports two kinds of files.  The first type that is check is if the
     file is in a.out(5) format.  If not, a couple of Digital's formats are

     In normal operation, mopd forks a copy of itself and runs in the
     background.  Anomalies and errors are reported via syslog(3).

     -a      Listen on all the Ethernets attached to the system.  If -a is
             omitted, an interface must be specified.

     -d      Run in debug mode, with all the output to stdout.  The process
             will run in the foreground.

     -f      Run in the foreground.

     -s      Change the directory to look for files in from /tftpboot/mop to


     mopd automatically appends an upper case .SYS to the filename provided by
     the client.  The typical client sends the requested file name in upper

     mopchk(1), mopcopy(1), mopprobe(1), moptrace(1), bpf(4)
