dnetnml - DECnet Network Management Listener
dnetnml is a daemon that serves incoming management requests from
remote systems, usually NCP in the case of VMS and RSX. It is
recommended that the daemon be run from dnetd by adding the following
line to /etc/dnetd.conf:
NML 19 N nobody dnetnml
Currently it only serves a subset of information requests. These are
(in NCP terms):
SHOW KNOWN NODES
SHOW ADJACENT NODES
SHOW EXEC CHAR
SHOW KNOWN OBJECTS
SHOW KNOWN LINKS
Note that for SHOW KNOWN OBJECTS to work, /etc/dnetd.conf needs to be
readable by the daemon user (usually ’nobody’) or it will return a
Privilege Violation. There is no sensitive data in this file so it’s
quite OK to set the permissions to 0644. Though this is not the
-d Don’t fork and run the background. Use this for debugging.
-v Verbose. The more of these there are the more verbose dnetnml
will be. Don’t use more than one for normal operation because it
will seriously impair performance.
-h -? Displays help for using the command.
-V Show the version of dnetnml.
Probably lots, particularly as some of the functions are undocumented
and I’ve had to reverse-engineer them. SHOW KNOWN LINKS doesn’t show
quite the same information as VMS does. dnetnml relies on the
information it can get from /proc/net/decnet so it can’t show load PIDs
or processes unfortunately.
