Logging to /dev/console
Hi,
The output of the cat ttys on a free BSD m/c
console none unknown off secure
#
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.9600" unknown on secure
ttyd1 "/usr/libexec/getty std.9600" dialup off
ttyd2 "/usr/libexec/getty std.9600" unknown off
ttyd3 "/usr/libexec/getty std.9600" unknown off
# Pseudo terminals
ttyp0 none network secure
ttyp1 none network secure
ttyp2 none network secure
ttyp3 none network secure
ttyp4 none network secure
ttyp5 none network secure
ttyp6 none network secure
ttyp7 none network secure
ttyp8 none network secure
ttyp9 none network secure
If I login to m/c's console using using pty command, what would /dev/console be mapped to. If I issue a ls command, I see that it is of size zero and it is not linked to /dev/tty's. Now if I want to redirect my log messages to the console and I edit my syslog.conf file to write the log messages to /dev/console, where would the messages get redirected.
Thanks in advance,

TTYTAB() TTYTAB()
NAME
ttytab - table of login terminals
SYNOPSIS
/etc/ttytab
DESCRIPTION
The ttytab file lists all the terminal devices that one can login on. It is a simple text file that contains lines of the form:
name type "getty" "init"
The name and type fields are simple words, name is the name of the terminal device with /dev stripped off, and type tells the type of ter-
minal to initialize the TERM environment variable.
The getty and init fields may name commands that are run to allow one to login on the line, or to initialize the line. Both these fields
may be more than one word if the whole field is enclosed in double quotes. Getty is usually simply the word getty, the command that prints
a system identification banner and allows on to type a name to log in. Init is usually an stty command to set the baud rate and parity of
a serial line.
The init field may be omitted to indicate that no initialization is necessary, and the getty field may be left out to not start a login
process. Terminals should not be left out, because their place in the ttytab file determines their slot number as returned by ttyslot(3).
Comments (introduced by #) and empty lines are ignored.
EXAMPLE
A ttytab for the console, two serial lines, and a pseudo tty entry:
console minix getty
tty00 vt100 getty "stty 9600"
tty01 dialup getty "stty 38400"
ttyp0 network
ENVIRONMENT
TERM Terminal type
NOTES
It is customary to set the type to dialup for a dialin line. One can check for that name in one's .profile.

gettyent(3), ttyslot(3), init(8).
