Java 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,
Lalitha.M

systemd-getty-generator

SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					SYSTEMD-GETTY-GENERATOR(8)

NAME

       systemd-getty-generator - Generator for enabling getty instances on the console

SYNOPSIS

       /lib/systemd/system-generators/systemd-getty-generator

DESCRIPTION

       systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console(s), if they can function
       as ttys and are not provided by the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer
       consoles, if execution in a virtualized environment is detected. If execution in a container environment is detected, it will instead
       enable console-getty.service for /dev/console, and container-getty@.service instances for additional container pseudo TTYs as requested by
       the container manager (see Container Interface[1]). This should ensure that the user is shown a login prompt at the right place, regardless
       of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line
       argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more information
       on the console= kernel parameter.

       systemd-getty-generator implements systemd.generator(7).

       Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
       Elsewhere)[3].
