Author Topic: DOLBY SERVERS, setting TIME Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 07-30-2014 07:00 PM                     quote: Marco Giustini Is the 745 up and running (projector on) when the system is rebooted? Yes, they always need to power up the projector before starting the DSS200. It's a bit complicated to communicate with him. It would be interesting to set the secure clock, then shut down the server, power on and go into the BIOS directly to see how the BIOS clock ended up. He was actually successful to get the time 'right' by connecting a windows laptop with registry enabled NTP server, set to the Dolby configured NTP server IP address displayed during boot. Quick hack. So it seems he is not completely illiterate. Just that, when he disconnects the notebook, the Dolby again reverts to the wrong secure clock, as this is not synced to NTP, at least not easily, as Steve explained. I understand that the secure clock will NEVER be synced to NTP, only manual adjustment is possible? I wouldn't care about the secure clock being off as long as I can adjust it manually often enough within allowed limits. Show manager clock/system clock being constantly off is the annoying thing. They have two DSS200/745 combos in distant booths, with no cabling in between. I suggested to start with a bare patch cable between the servers, he will try to get this going. They have a router with it's own LAN side NTP server, itself being synced from a WAN NTP server. Once they are networked, this router could be a cheap option. - Carsten  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 07-31-2014 03:03 AM                     I am not 100% sure but I believe the 745 will eventually sync to the server ONLY if the NTP daemon trusts the server's NTP, which is very unlikely to happen on a Dolby server for how the NTP protocol has been designed. Again, the NTP daemon can realise if the server which is supposed to sync to is not synced to anything and will refuse to lock on it if that is the case. The reason why a Dolby will sync to any computer running an NTP server when booted up, regardless whether the computer is properly locked to a reliable NTP source, is because the startup script contains a ntpdate command, just before the NTP service is started. ntpdate will sync the time straight away, regardless of the conditions of the time source. But then the NTP daemon will refuse to lock to the source if the source reports it's not locked to a reliable NTP source. If you sync your server using an NTP and then shut it down, you will find the BIOS has not been changed. As said, the BIOS is synced to the system time when Linux is properly shut down.  |  IP: Logged Kevin Fairchild Expert Film Handler Posts: 125 From: Kennewick, WA, USA Registered: Oct 2008 posted 08-02-2014 10:06 PM                     quote: Marco Giustini tell him to press CTRL-ALT-F1 and then CTRL-ALT-DEL Linux as default saves the system clock to the BIOS when the system is shutting down THANK YOU! I tried this and confirmed it works. You can also login and reboot over SSH as administrator.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 08-03-2014 05:15 PM                     Thank you, I wasn't sure it would work. Yes, you can also run the reboot script, but that's mainly for remote purpose, where you can't press CTRL-ALT-DEL! I still feel Dolby should add a "reboot" button, it escapes me why they're not adding one.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-03-2014 06:12 PM                     I would like a reboot script that is executable via serial/Ethernet. There is the "power" button behind the bezel.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 08-03-2014 06:14 PM                     There is, reboot.sh, scripts folder. Oh wait, you mean to reboot by ethernet RAW command or serial? Why? I can shutdown my NAS by SSH, you may be able to do so with a Linux server. I can't remember the name of the command line SSH programme, I'll need to check, but you can send username, password and a single instruction on a single CLI line. It should work, after all it's Linux. The power button removes power, I want a 'reboot' software button, I can't see why there isn't one.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-03-2014 06:26 PM                     I'd like to schedule "graceful" reboots rather than hard yanking of the power. Even if the routine is to do a graceful shutdown...yank power...reapply power...boot up. I never liked the idea of just yanking the power.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 08-03-2014 06:39 PM                     neither have I. That's why I'd like to see a "reboot" and "shutdown" button on the GUI. I believe it could have been putty - not home now, I'll check later, but you can try with c:\putty.exe -ssh administrator@dolby_IP -pw {password} reboot or whatever reboots a Linuz system, maybe "reboot now"? I believe that c:\putty.exe -ssh administrator@dolby_IP -pw {password} halt should shut it down. You may be to ssh with root privileges though. It's worth a try, it works on my NAS  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 08-04-2014 01:55 AM                     I just putty in as administrator and issue 'reboot'.  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 08-04-2014 04:08 AM                     I believe Steve is looking for a way to automate the reboot.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-04-2014 06:17 AM                     That is correct...Using PuTTY to reboot is simple enough but I'd like our automation (eCNA) to be able to issue a periodic reboot command.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 08-04-2014 07:09 AM                        Steve--what can your automation system do? Just send serial commands or make TCP connections to a specific port? How much do you trust the local network and are you willing to modify the operating system in a way that Dolby might not appreciate? If you have a totally trusted network, the simplest solution would be to set up an inetd service that accepts TCP connections on a particular port and calls /sbin/reboot when a particular string is sent to that port. Alternatively, you could enable the serial console and have the automation send a root-level username and password and the command /sbin/reboot to it. (This would not work if the Dolby server uses the serial port for anything internally. Does it?)  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 08-04-2014 09:38 AM                     Ah I see Steve, sorry I didn't catch that fully. How about a Raspberry Pi or similar device running a script on command or schedule? I've a couple of routers here that are set to auto-reboot at 06:00 every Sunday.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-05-2014 11:13 AM                     Since are RS232 automation can send serial back to the server on a dry contact closure i guess it would be possible to schedule a SPL to tell it to send back to the server a shut down command Currently in our non vpf houses that power down each night we have a shut down SPL that tells the server to power off and projector go to standby  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-06-2014 03:30 AM                     Gordon, but that is not on a Dolby server, right? - Carsten  |  IP: Logged
