      Is there any known issues getting LCDProc running on the nano versions?

      I converted my Firebox X700 to nano on CF instead of a HDD install and I cannot get the package to run correctly.  The package installer shows success but I cannot get the display operational and on boot I get the following error:

      
 Starting package LCDproc-dev...
Warning: fopen(/usr/local/etc/LCDd.conf): failed to open stream: Read-only file system in /usr/local/pkg/lcdproc.inc on line 43
Bootup complete

      Line 43 is```
      $handle = fopen($file, 'w');

      
I had this working perfectly on the full HDD version.

        Hmm, that's odd.
        The package system should take care of the filesystem.

        What do you see from this command:

        mount -p

          This is the output

           mount -p
/dev/ufs/pfsense0       /                       ufs     rw,sync,noatime        1 1
devfs                   /dev                    devfs   rw              0 0
/dev/md0                /tmp                    ufs     rw              2 2
/dev/md1                /var                    ufs     rw              2 2
/dev/ufs/cf             /cf                     ufs     rw,sync,noatime        1 1
devfs                   /var/dhcpd/dev          devfs   rw              0 0

          Forgot to mention that this is on 2.1-Dev  Everything else is working great including the OpenVPN Client Export package which is the only other package installed.

            mdima,

            I have an iMonLCD (OEM type) and I found that it should be supported on 0.5.5 package on this document:
            http://lcdproc.sourceforge.net/docs/lcdproc-0-5-5-user.html

            However, after install the LCDProc 0.5.5 package, the support for iMon is missing.

            Is there any way to bring it back?

              In that case it's untested and you're on your own.  ;) Interesting to note though.
              However there's clearly something not right because your filesystem is mounted RW and it should be RO for Nano installs. I think I may have read something about that recently, check the 2.1 sub forum.

              Edit: Did you test from the cli or using the Diag: Command: in the web gui?

                It appears that the iMon LCDproc driver requires a kernel module in order to work. The links provided in the document are all Linux based. If there isn't a FreeBSD module then it's very unlikely.  :(

                  is there a way to get a temperature screen added?

                  wondering if the code that is used for the system information widget/functions.inc.php could be helpful

                  
function get_temp() {
//	switch(get_hwtype()) {
//		default:
//			return;
//	}
//
//	return $ret;

         $temp_out = "";
	 exec("/sbin/sysctl dev.cpu.0.temperature | /usr/bin/awk '{ print $2 }' | /usr/bin/cut -d 'C' -f 1", $dfout);
         $temp_out = trim($dfout[0]);
         if ($temp_out == "") {
           exec("/sbin/sysctl hw.acpi.thermal.tz0.temperature | /usr/bin/awk '{ print $2 }' | /usr/bin/cut -d 'C' -f 1", $dfout);
   	   $temp_out = trim($dfout[0]);
         }

	 return $temp_out;
}

                  thanks in-advance!

                    I was afraid of that :)

                    I thought so too, but being new to the nano version, I wasn't sure…

                    I may end up grabbing the newest SNAP and starting over when I get a chance this weekend.  I have some 'other' 2.1-dev issues that seem to be resolved on a clean install of the newest SNAPs….

                    edit:  stephenw - you are right.  There seems to be some issues with CF cards 'hanging' and causing slow response, mine included.  http://forum.pfsense.org/index.php/topic,48256.0.html

                      Hello,

                      I am running the latest version of the driver package installed with the web UI.

                      The LCDproc server stops after a while setting "thanks for using pfsense" in the display.
                      Restarting the server works but the the behaviour occures after a while.

                      I used the version (0.5.3 I think) without any problems.

                      Is there anyone who is interested in any logfiles (if so, which are of interest?).
                      If not, where can I get an older version of the package?

                      Matthias

                        What LCD do you have? Which driver?
                        Edit: I see you're using a firebox.
                        I have seen this behaviour at start up but not during normal running. Does it coincide with an IP change or an interface going up or down, when packages are restarted?

                        The old firebox lcd driver, which was 0.52 then 0.53, was not a pfSense package and as such it was only ever started once at boot. Currently there is an unresolved issue with the package being restarted multiple times during boot. This seems cause a problem with LCDd which cannot start/stop fast enough. On my box the daemon/client often ends up running incorrectly but after restarting manually it runs fine until I next reboot the box.

                          Here's a suggestion, while reading through some other bootup scripts I found this:

                          
// Do not process while booting
if($g['booting']) 
	exit;

                          Perhaps we could use this somehow to limit the number of reloads? Of course it could easily stop it loading at all.  ::)

                          Steve

                          Just some news about this function if still needed.

                          I found a way to detect and prevent multiple starts during boot.
                          here is the code I'm including on packages I'm maintaining

                          	# detect boot process
	if (is_array($_POST)){
		if (preg_match("/\w+/",$_POST['__csrf_magic']))
			unset($boot_process);
		else
			$boot_process="on";
	}

	if(is_process_running("NAME_OF_DAEMON_PROCESS_HERE") && isset($boot_process))
		return;

                            This looks good. I'll try and test it ASAP. Unfortunately my replacement X-Core has a dead backlight on the LCD.  ::)
                            Hopefully I can combine my two boxes to make one reliable one.  :)

                            Are you including this code in the rc file?

                              No, it's on sync function at inc package file.

                              on postfix.inc for example:

                              function sync_package_postfix() {
	global $config;

	# detect boot process
	if (is_array($_POST)){
		if (preg_match("/\w+/",$_POST['__csrf_magic']))
			unset($boot_process);
		else
			$boot_process="on";
	}

	if(is_process_running("master") && isset($boot_process))
		return;

	#check patch in /etc/inc/config.
	$relay_domains = "";
	$transport = "";
.

                                It's still hard to get a grip on why this is failing.
                                The package is initially started and the LCDd daemon successfully connects to the client on socket 11. Then all packages are restarted. For some reason the LCDd instance fails to stop quickly and a new one tries to start but can't because port 13666 is in use. Then the first instance stops and the client times out.  :-\

                                  Try this way:

                                  function sync_package_lcdproc_screens() {
	# detect boot process
		if (is_array($_POST)){
			if (preg_match("/\w+/",$_POST['__csrf_magic']))
				sync_package_lcdproc();
			}

	}

	function sync_package_lcdproc() {
		global $g;
		global $config;
		global $input_errors;		

		# detect boot process
		if (is_array($_POST)){
			if (!preg_match("/\w+/",$_POST['__csrf_magic']))
				return;
			}

		lcdproc_notice("Sync: Begin package sync");
		config_lock();
.
.

                                    The problem is not that it's syncing multiple times, it's that the package is started and then restarted multiple times.
                                    Adding the boot detection in the sync function cuts this down, since it normally restarts the package after a sync if it's already running, but it's still a problem.

                                    Here's the function I'm testing with:

                                    
	function sync_package_lcdproc_screens() {
		sync_package_lcdproc();
	}	
	function sync_package_lcdproc() {
		global $g;
		global $config;
		global $input_errors;

		# detect boot process and prevent syncing
		if (is_array($_POST)){
		if (preg_match("/\w+/",$_POST['__csrf_magic']))
			unset($boot_process);
		else
			$boot_process="on";
		}
		if(is_process_running("LCDd") && isset($boot_process)){
		lcdproc_notice("Sync: Still Booting!");
		return;
		}

		lcdproc_notice("Sync: Begin package sync");
		config_lock();
....etc

                                    You can see it in the logs once for each sync, lcdproc and lcdproc_screens:

                                    
May 7 18:24:18 	php: : Restarting/Starting all packages.
May 7 18:24:18 	php: lcdproc: Sync: Still Booting!
May 7 18:24:18 	php: lcdproc: Sync: Still Booting!

                                    However it still goes on to restart lcdproc and for some reason that causes a problem during boot.
                                    Restarting the package at any other time works fine.

                                    It would be better to prevent the package restarting during boot but the rc file is a shell script not a php file so I have no idea how that might be done.  :-\

                                    Thanks for looking at this.

                                      I've tested the code on a virtual machine, and it started once. It crashed after because there is no lcd display attached.

                                      The sync process for each xml file is called by pfsense during boot, that's why I've configured the code there.
                                      After the sync process, the last step is to call all .sh files in /usr/local/etc/rc.d.

                                      Other point is that lcd binary is a php script(all I could see on my teste), so it's quite impossible to determine what php is lcd driver call on current function "is_process_running"

                                      Here is my virtual machine boot log in reverse order.
                                      Check if it starts the way you need.

                                        Hmm, not really sure what I'm looking at but it looks like the LCD process is only started once so that's good.  ;)

                                          If you want, I can commit the code.

                                            What code are you referring to? Nothing I've tried, and I've tried many variations, has started up correctly.  :(
