	== ~~Central~~ Logging ==		== Logging Centralizzato ==
	~~One thing I found very useful when~~ debugging ~~issues with~~ OSCam (~~and not only this~~) ~~is to have all the logs at my disposal~~. ~~To do that~~, ~~I have setup all my boxes to send their~~ logs ~~to my~~ server ~~which is always on and has sufficient disk space~~. ~~The preferred protocol, supported by all devices and programs, is~~ '''syslog'''.		Un importante passo per eseguire il debugging di OSCam (e non solo) è sicuramente quello di avere tutti i log in un unico posto per poterli analizzare in maniera più semplice. Per fare questo, si devono configurare tutti i decoders (ricevitori o apparecchi da analizzare) in modo che inviino i loro logs su un server con sufficiente spazio disco per mantenere tutti questi logs. Il protocollo preferito per eseguire questa attività è '''syslog'''.

	=== Client ~~Configuration~~ ===		=== Configurazione del Client ===
	~~First, I make sure~~ syslog ~~is running on my boxes~~.		Controllare che syslog sia funzionante su tutte le periferiche.

	~~For~~ DM500 ~~running~~ Gemini, ~~the configuration is~~ in <tt>/var/script/syslogd_script.sh</tt>:		Per DM500 con Gemini, la configurazione si trova in <tt>/var/script/syslogd_script.sh</tt>:
	REMOTE=1		REMOTE=1
	REMOTE_HOST=<serverIP>		REMOTE_HOST=<serverIP>
	REMOTE_PORT=514		REMOTE_PORT=514

	~~On my~~ TM800HD, ~~the configuration is~~ in <tt>/etc/syslog.conf</tt>		Per TM800HD, la configurazione si trova in <tt>/etc/syslog.conf</tt>
	DESTINATION="remote"		DESTINATION="remote"
	REMOTE=<serverIP>:514		REMOTE=<serverIP>:514

	~~Then~~, '''oscam''' ~~can be configured to write to~~ syslog ~~daemon instead of a~~ file. ~~Just change~~ <tt>logfile</tt> ~~value~~ in <tt>oscam.conf</tt> ~~like this~~:		Poi, '''oscam''' può essere configurata per scrivere il proprio log sul demone di syslog invece che in un semplice file. Basta cambiare il valore di <tt>logfile</tt> in <tt>oscam.conf</tt> in questo modo:
	[global]		[global]
	logfile = syslog		logfile = syslog

	=== Server ~~Configuration~~ ===		=== Configurazione Server ===
	~~The best part is on the~~ server ~~side~~. ~~This is where I wasn't happy with the default~~ '''syslogd''' ~~server that comes with Debian, and I installed the smarter~~ '''syslog-ng'''. ~~One thing I loved about~~ syslog-ng ~~is that I was able to configure it so that each box has its own~~ directory ~~on the server~~, ~~making it very easy to find the log data I was looking for. This is the configuration I use in <tt>syslog-ng~~.~~conf</tt>:~~		La parte migliore si trova lato server. Per i possessori di Debian è consigliato sostituire '''syslogd''' con '''syslog-ng'''. syslog-ng presenta dei vantaggi notevoli rispetto a syslogd (o rsyslogd), uno dei quali è ad esempio che ogni periferica può avere a disposizione la propria directory dedicata dove inviare i propri logs, rendendo molto più semplice la ricerca e l'analisi degli stessi.

	# ~~source~~: ~~all logs sent from the network~~		Configurazione di esempio in <tt>syslog-ng.conf</tt>:

			# sorgente: Tutti i log provenienti dalla rete
	source s_net {		source s_net {
	udp();		udp();
Zeile 32:		Zeile 34:
	syslog();		syslog();
	};<br/>		};<br/>
	# ~~destination~~: ~~each facility has its own log for each host~~		# destinazione: ogni decoder ha la propria directory
	destination d_hosts {		destination d_hosts {
	file("/var/log/hosts/$HOST/$FACILITY.log"		file("/var/log/hosts/$HOST/$FACILITY.log"
Zeile 42:		Zeile 44:
	);		);
	};<br/>		};<br/>
	# ~~everything from the network is sent to the disk, under~~ /var/log/hosts		# tutto ciò che proviene dalla rete viene inviato al disco in /var/log/hosts
	log {		log {
	source(s_net);		source(s_net);
Zeile 48:		Zeile 50:
	};		};

	=== ~~Results~~ ===		=== Risultati ===

== Central Logging ==
One thing I found very useful when debugging issues with OSCam (and not only this) is to have all the logs at my disposal. To do that, I have setup all my boxes to send their logs to my server which is always on and has sufficient disk space. The preferred protocol, supported by all devices and programs, is '''syslog'''.

=== Client Configuration ===
First, I make sure syslog is running on my boxes.

For DM500 running Gemini, the configuration is in <tt>/var/script/syslogd_script.sh</tt>:
REMOTE=1
REMOTE_HOST=<serverIP>
REMOTE_PORT=514

On my TM800HD, the configuration is in <tt>/etc/syslog.conf</tt>
DESTINATION="remote"
REMOTE=<serverIP>:514

Then, '''oscam''' can be configured to write to syslog daemon instead of a file. Just change <tt>logfile</tt> value in <tt>oscam.conf</tt> like this:
[global]
logfile = syslog

=== Server Configuration ===
The best part is on the server side. This is where I wasn't happy with the default '''syslogd''' server that comes with Debian, and I installed the smarter '''syslog-ng'''. One thing I loved about syslog-ng is that I was able to configure it so that each box has its own directory on the server, making it very easy to find the log data I was looking for. This is the configuration I use in <tt>syslog-ng.conf</tt>:

# source: all logs sent from the network
source s_net {
udp();
tcp();
syslog();
};<br/>
# destination: each facility has its own log for each host
destination d_hosts {
file("/var/log/hosts/$HOST/$FACILITY.log"
owner(root)
group(root)
perm(0600)
dir_perm(0755)
create_dirs(yes)
);
};<br/>
# everything from the network is sent to the disk, under /var/log/hosts
log {
source(s_net);
destination(d_hosts);
};

=== Results ===
The result is that I have log files on the server for all my stuff:
server:/var/log/hosts# find
./phone
./phone/user.log
./dm500fe
./dm500fe/daemon.log
./dm500fe/syslog.log
./dm500fe/user.log
./server
./server/daemon.log
./server/syslog.log
./server/user.log
./tm800
./tm800/daemon.log
./tm800/authpriv.log
./tm800/cron.log
./tm800/user.log
./dm7000
./dm7000/daemon.log
./dm7000/syslog.log
./dm7000/user.log
./dm500be
./dm500be/daemon.log
./dm500be/syslog.log
./dm500be/user.log

Here's my son watching Cartoons:
server:/var/log/hosts/dm500fe# tail -2 daemon.log
Mar 17 12:53:15 dm500fe oscam: 32025B50 c anonymous (0500&022F00/003D/34:EF9E): found (143 ms) by server (of 1 avail 1)
Mar 17 12:53:25 dm500fe oscam: 32025B50 c anonymous (0500&022F00/003D/34:E49B): found (147 ms) by server (of 1 avail 1)

I'm watching cricket on Sky Sports HD1:
server:/var/log/hosts/tm800# tail -2 daemon.log
Mar 17 12:54:23 tm800 oscam: 2CDE74D0 c anonymous (0963&000000/0EDA/76:11B0): found (135 ms) by server (of 1 avail 1)
Mar 17 12:54:30 tm800 oscam: 2CDE74D0 c anonymous (0963&000000/0EDA/76:FB59): found (117 ms) by server (of 1 avail 1)

Even the server logs are in this directory structure:
server:/var/log/hosts/server# tail -2 daemon.log
Mar 17 12:55:44 server oscam: B6419280 c tm800 (0963&000000/0EDA/76:85F5): found (111 ms) by smargo (of 1 avail 1)
Mar 17 12:55:45 server oscam: B6421280 c dm500fe (0500&022F00/003D/34:8660): found (142 ms) by omnikey (of 1 avail 1)

'''NOTE:''' In case you are wondering, phone is a VOIP adapter. Yes, it supports the '''syslog''' protocol, so I collect its logs on my server!
