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
-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
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
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
-ais 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.
