	<p>
		Compilando questo form uno script effettuer&agrave; una connessione SSH con la tua macchina, cercher&agrave; il file di configurazione SAMBA (smb.conf) e ne far&agrave; un parser.<br />
		Lo script esegue operazioni in sola lettura, e ha valore esemplificativo della possibilit&agrave; di automatizzare un'installazione via remoto tramite interfaccia web.<br />
		Il comando che verr&agrave; eseguito sulla macchina da te indicata &egrave;:<br /><tt>$ cat $(find / -type f -name "smb.conf" -print 2>/dev/null -quit)</tt>.<br />
