# NAME

`mopd` — Maintenance Operations Protocol (MOP) Loader Daemon

# SYNOPSIS

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

# DESCRIPTION

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

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 the filename, e.g., 08002b09f4de.SYS, and it might be a soft link to another file.

`mopd` supports two kinds of files. The first file type checked for is the a.out(5) 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).

# OPTIONS

`-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 mopdir.

# FILES

/tftpboot/mop

# NOTES

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