Solaris Terminal Handling
Instead of using gettys like most normal Unix versions, Solaris uses SAF, (Service Access Facility) to control terminal lines, serial printers and modems. This works as follows:
1. At the top level is SAC (Service Access Controller), this is started in inittab (/usr/lib/saf/sac) 2. SAC starts the port monitors listed in /etc/saf/_sactab 3. Two different port monitors exist ttymon and listen 1. ttymon is responsible for terminal lines, (typically /dev/term/ a and /dev/term/b). Generally it calls the login program as defined in /etc/saf/zsmon/_pmtab 2. listen controls printing (although it has capabilities to control more). It calls the lp facility.
- sacadm - High level SAF configuration. Add, delete, enable, disable, start and stop port monitors.
- pmadm - Configure port monitors
- ttyadm - Helper utility to format input to pmadm
- sttydefs - Create amd modify entries in /etc/ttydefs (file describing terminal line characteristics).
- nlsadmin - helper utility to format input to pmadm for printers.
* sacadm -l - lists port monitors * sacadm -a -p tcp -t listen -c "/usr/lib/saf/listen tcp" -v `nlsadmin -v` -n 9999 - will define the listen port monitor if, for some reason, it wasn't preinstalled. Flags are as follows: -a add a port monitor -t port monitor type (listen or ttymon) -p PMTAG (generally zsmon for ttymon and tcp for listen -c command to run for associated port monitor -v version number (given by nlsadmin helper command -y description for /etc/saf/tcp/_pmtab entry -n number of restarts if monitor dies The subdirectory /etc/saf/tcp will be created by the above command. The monitor must now be configured with the pmadm command, e.g. * pmadm -a -p tcp -s lp -i root -v `nlsadmin -v` -m "`nlsadmin -o /var/ spool/lp/fifod/listen S5`" * pmadm -l - will list the port monitors configuration details
