===== Operation manuals =====
==== Configure System log (syslog) Server ====
Raspbian (debian) server can be used as a machine recording log from external devices such as router. \\
Install syslog-ng and related mods as well.
sudo apt-get install syslog-ng
After finishing installation, edit ''/etc/syslog-ng/syslog-ng.conf''. \\
source s_net { udp(ip(0.0.0.0) port(514)); };
destination d_router { file(“/var/log/router.log”); };
log { source(s_net); destination(d_router); };
''source s_net'' defines the source where records are from ''0.0.0.0'' will be bind to all interfaces. \\
''destination'' set your arbitrary name like ''d_router'' and set the path of log file. \\
''log'' tells what source to use and what destination to take. If you have 'filter' option to utilize for more refined log results. \\
Create log file.
sudo touch /var/log/router.log
And restart ''syslog-ng'' service
sudo systemctl stop syslog-ng.service
sudo systemctl start syslog-ng.service
For sensitive reason, you would better to **stop & start** service instead of restart. \\
Check size of log file is getting bigger and contents of log file.
For archiving and compressing log files, ''edit'' ''/etc/logrotate.d/syslog.ng''
/var/log/router.log
{
rotate 4
weekly
missingok
notifempty
compress
delaycompress
sharedscripts
postrotate
invoke-rc.d syslog-ng reload > /dev/null
endscript
}

==== Delete unnecessary files regularly ====
''sudo crontab -e'' Add command line to find & delete. e.g.) Delete all ''.nfo'' file in target directory and its sub-directories at 30 minutes past every 6 hours.
30 */6 * * * /usr/bin/find /..((your path)).../ -name '*.nfo' -exec rm -f {} \;
Delete empty directory at 30 minutes past every 12 hours
30 */12 * * * /usr/bin/find /..((your path)).../ -type d -empty -delete
