services MOP Load requests on the Ethernet connected to interface or all interfaces if is given. In a load request received by mopd a filename can be given. This is the normal case for e.g. terminal servers. If a filename isn't given mopd must know what image to load.

Upon receiving a request, mopd checks if the requested file exists in /tftpboot/mop , the filename is normally uppercase and with an extension of .SYS . If the filename isn't given, the ethernet address (in lower case, apart from the .SYS) of the target is used as the 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() format. If not, a couple of Digital's formats are checked.

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 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.
