What is logged, to where, reports, and to whom.

Installed as the default Debian logging setup.

Change KLOGD line to read:

KLOGD="-c 5"

to turn off console messages for lower priority messages.

Technically, we should be changing the kernel.printk line in /etc/sysctl.conf instead, but that has not yet been tested.

Edit /etc/logrotate.conf to change the rotate option for /var/log/wtmp from 1 to 25, and /var/log/btmp from 1 to 13.

Add option dateext to change the naming convention of adding generation numbers ".1", ".2", etc. to the "-yyyymmdd" format. Also manually rename all existing log files to the new format. Note this is the default in later releases.

Fix incorrect permissions for the /var/log/btmp entry from 0660 to 0600. Also chmod existing files to make the same change. This is a well known bug fixed in later releases, but should be verified.

Everything at level of info other than kern.info and mail.info goes to /var/log/messages. That was accomplished with:

news.info;daemon.info;\
      auth.info;authpriv.info;\
      cron.info;syslog.info;\
      user.info               -/var/log/messages

#			For more information see syslog.conf(5)
#			manpage.

# The named pipe /dev/xconsole is for the `xconsole' utility.  To use it,
# you must invoke `xconsole' with the `-file' option:

#    $ xconsole -file /dev/xconsole [...]
