DAEMON.MN(M) XENIX System V DAEMON.MN(M)
Name
daemon.mn - Micnet mailer daemon
Syntax
/usr/lib/mail/daemon.mn [-ex]
Description
The mailer daemon performs the ``backend'' networking
functions of the mail, rcp, and remote commands by
establishing and servicing the serial communication link
between computers in a Micnet network.
When invoked, the daemon creates multiple copies of itself,
one copy for each serial line used in the network. Each
copy opens the serial line, creates a startup message for
the LOG file, and waits for a response from the daemon at
the other end. The startup message lists the names of the
machines to be connected, the serial line to be used, and
the current date and time. If the daemon receives a correct
response, it establishes the serial link and adds the
message ``first handshake complete'' to the LOG file. If
there is no response, the daemon waits indefinitely.
If invoked with the -x switch, the daemon records each
transmission in the LOG file. A transmission entry shows
the direction of the transmission (tx for transmit, rx for
receive), the number of bytes transmitted, the elasped time
for the transmission (in minutes and seconds), and the time
of day of the transmission (in hours, minutes, and seconds).
Each entry has the form:
direction byte_count elasped_time time_of_day
The daemon also records the date and time every hour. The
date and time have the same format as described for the date
command.
If invoked with the -e switch, the daemon records all
transmission errors in the LOG file. An error entry shows
the cause of the error preceded by the name of the daemon
subroutine which detected the error.
The mailer daemon is normally invoked by the start option of
the netutil command and is stopped by the stop option.
During the normal course of execution, the mailer daemon
uses several files in the /usr/spool/micnet/remote
directory. These files provide storage for LOG entries,
commands issued by the remote(C) command, and a list of
processes under daemon control.
