exec chpst -Unobody socklog unix /dev/log

A sample socklog-unix/log/run script:

#!/bin/sh

  main/main main/auth main/cron main/daemon main/debug main/ftp \
  main/kern main/local main/mail main/news main/syslog main/user

Sample log config files:

# cat main/config

# cat debug/config
s999999
n5

+*.debug*

If you want additional tai64n time-stamps prepended to each message, use this socklog-unix/log/run script as example:

#!/bin/sh
exec chpst -ulog svlogd -t \
  main/main main/auth main/cron main/daemon main/debug main/ftp \
  main/kern main/local main/mail main/news main/syslog main/user

Listening on udp network socket 0.0.0.0:514:

A sample socklog-inet/run script is:

#!/bin/sh
exec 2>&1
exec chpst -Unobody socklog inet 0 514

A sample socklog-inet/log/run script is:

#!/bin/sh
exec chpst -ulog svlogd -t main/main

Reading kernel messages from /dev/klog on BSD:

A sample socklog-klog/run script on BSD:

#!/bin/sh
exec </dev/klog
exec 2>&1
exec chpst -unobody socklog ucspi

A sample socklog-klog/log/run:

#!/bin/sh
exec chpst -ulog svlogd -t main/main

A client for socklog network logging:

A sample socklog-unix/log/run script and log config file that transmits the logs to a network logging server running the socklog-ucspi-tcp service on 10.0.0.16:10116 is (you need to have the netcat package installed):

#!/bin/sh

!tryto -pv nc -q0 10.0.0.16 10116

Log events notification with wall:

A sample socklog-notify/run script that uses wall for notification is:

#!/bin/sh -e
PIPE=/var/log/socklog/.notify
if [ ! -p "$PIPE" ]; then mkfifo -m0620 "$PIPE"; chown log:adm "$PIPE"; fi
exec <> "$PIPE"
exec chpst -ulog uncat -s49999 -t180 sh -c 'head | wall'
