What has happened to getty? What is pmadm and how do you use it?



I was hoping you wouldn't ask. PMadm stands for Port Monitor Admin,
and it's part of a ridiculously complicated bit of software
over-engineering that is destined to make everybody an expert.


Best advice for workstations: don't touch it! It works out of the box.
For servers, you'll have to read the manual.
This should be in admintool in Solaris 2.3 and later.
For now, here are some basic instructions from Davy Curry.


"Not guaranteed, but they worked for me."


To add a terminal to a Solaris system:


1. Do a "pmadm -l" to see what's running. The serial ports on the
CPU board are probably already being monitored by "zsmon".



PMTAG PMTYPE SVCTAG FLGS ID <PMSPECIFIC>
zsmon ttymon ttya u root \
/dev/term/a I - /usr/bin/login - 9600 ldterm,ttcompat ttya \
login: - tvi925 y #


2. If the port you want is not being monitored, you need to create a
new port monitor with the command



sacadm -a -p PMTAG -t ttymon -c /usr/lib/saf/ttymon -v VERSION


where PMTAG is the name of the port monitor, e.g. "zsmon" or "alm1mon",
and VERSION is the output of "ttyadm -V".


3. If the port you want is already being monitored, and you want to
change something, you need to delete the current instance of the port
monitor. To do this, use the command



pmadm -r -p PMTAG -s SVCTAG


where PMTAG and SVCTAG are as given in the output from "pmadm -l". Note
that if the "I" is present in the <PMSPECIFIC> field (as it is above),
you need to get rid of it.


4. Now, to create a specific instance of ttymon for a port, issue the
command:



pmadm -a -p PMTAG -s SVCTAG -i root -fu -v 1 -m \
"`ttyadm -m ldterm,ttcompat -p 'PROMPT' -S YORN -T TERMTYPE \
-d DEVICE -l TTYID -s /usr/bin/login`"


Note the assorted quotes; Bourne shell (sh) and Korn (ksh) users
leave off the second backslash!


In the above:


PMTAG is the port monitor name you made with "sacadm", e.g. "zsmon".


SVCTAG is the service tag, which can be the name of the port, e.g.,
"ttya" or "tty21".


PROMPT is the prompt you want to print, e.g. "login: ".


YORN is "y" to turn software carrier on (you want this for directly
connected terminals" and "n" to leave it off (you want this
for modems).


TERMTYPE is the value you want in $TERM.


DEVICE is the name of the device, e.g. "/dev/term/a" or "/dev/term/21".


TTYID is the line you want from /etc/ttydefs that sets the baud rate
and stuff. I suggest you use one of the "contty" ones for
directly connected terminals.


5. To disable ("turn off") a terminal, run



pmadm -d -p PMTAG -s SVCTAG


To enable ("turn on") a terminal, run



pmadm -e -p PMTAG -s SVCTAG


Ports are enabled by default when you "create" them as above.
