Basic usage is very simple to create a panorama, with a set of pictures taken in a raw:

  • Press CTRL-N to create a new Panorama
  • Open the folder containing the pictures to be used, press CTRL-A to pick them all and press ENTER to continue
  • There a 4 steps: Import, Stitch, Crop and Export. For simple panorama, go directly to step 3.

Synology Create a VPN to download from a Synology

In order to hide my NAS, I wanted it to use its own VPN, while my public IP was still visible when surfing with any other devices in my LAN.

To do so, I subscribed to HMA! (HideMyAss!) and applied their configuration procedure on my Synology. Et voilà.

I did try both a L2TP and a OpenVPN VPN with success. Tricks:

  • For a L2TP VPN, use your PPTP password and NOT your account password
  • For a OpenVPN VPN, use your account password
  • Although using Port Forwarding to access my NAS from internet, I did not had to open the required ports !!!
    • L2TP: UDP 500, 4500 and 1701
    • Open VPN : 443 if using TCP, 553 is using UDL
  • If you are using a DDNS, go to the  Control Panel > External Access and Click Update to verify the public IP of your NAS. It must now be your VPN IP.
  • Check that downloading a torrent (with this procedure), your tracker IP is your VPN IP.
  • Check you IP calling ipify from your NAS.
    • A very simple way to do this is to call the following php page on your Web Station:
<?php 
 $ip = file_get_contents('https://api.ipify.org');
 echo "My public IP address is: " . $ip;
?>
  • Soon after enabling the VPN, I started to be attacked on Telnet port! I am using Security’s Auto-Block feature to prevent brute force attacks.
  • On a mobile device (or anything else) connected directly to Internet (not via your LAN), type your VPN IP in a browser. You should see the default home page of your web station if this one is enabled.
    • I would recommend to replace this default page by a php page returning a header 404.
<?php
 header("HTTP/1.0 404 Not Found");
?>
  • If you are using a DDNS on your NAS, you won’t be able to access your router and VDSL modem via that domain name. Indeed, only your NAS is accessible via this VPN IP. If possible, configure another DDNS on your VDSL modem or router.
    • Ex.: I am using duckdns.org for free. They have a great support page here with detailed configurations for many different devices.
    • Doing so, you can access your NAS and your router or modem via their own Domain name.
  • “Tested OK” both when accessed from LAN or from Internet:
    • Download Station via Synology Download Station for Chrome (https://www.download-station-extension.com)
    • JDownloader via Chrome extension and via https://my.jdownloader.org
    • Plex Server via App or via http://DDNS name:port/web or via http://plex.tv
    • DSM via its admin port
    • Apps: DS Cam, DS File, DS Audio, DS Get, DS Photo, DS Video, DS Cloud and DS Note are all wokring fine using Quick Connect (All those I tested via their DDNS name + custom port or DSM admin port worked too)
    • Cloud Sync (with Hubic)
    • FTP Server

Tips PC waking up in sleep mode

Recently, I noticed that my PC was waking up from sleep mode without me explicitly clicking the mouse, pressing a key on the keyboard or sending a magic packet…

I found this problem was due to an update of the Ethernet drivers which allowed any packet to wake up the computer…

This is a problem which comes back regularly when updating drivers. Each time, I wonder what’s wrong again. So, here are some tricks to find the cause.

First:

  • Put the computer at sleep and wait until it wakes up.

Next, look for the last device which turned on the PC:

  • Execute in a Dos prompt : powercfg -lastwake
C:\WINDOWS\system32>powercfg -lastwake
Wake History Count - 1
Wake History [0]
 Wake Source Count - 1
 Wake Source [0]
 Type: Device
 Instance Path: USB\VID_046D&PID_C52B\6&2b3c7d9c&0&3
 Friendly Name:
 Description: USB Composite Device
 Manufacturer: (Standard USB Host Controller)
Device 0xC52B is a USB Receiver for Wireless Mouse 
Vendor 0x046D is Logitech Inc.
  • Go into the Device Manager, find that device and open its properties. In its “Power Management” tab, disallow the device to turn on the computer. If the option is not available, this device is not causing your issue.
    • If your PC has been waked up by the Ethernet Controller, it can be because any packet can wake it up. In the Power Management tab, tick the option “Only allow a magic packet to wake the computer”.

If this does not help:

  • Open the “Event Viewer” (eventvwr) > “Windows Logs” > “System”.
  • “Filter Current Log” on “Event Source” = Power-Troubleshooter to find which device did wake up your PC:
The system has returned from a low power state.
Sleep Time: ‎2016‎-‎12‎-‎24T09:40:11.549148000Z
Wake Time: ‎2016‎-‎12‎-‎24T09:41:07.347715900Z
Wake Source: Device -Intel(R) Ethernet Connection (2) I219-V

You can also look for the list of devices able to wake up the PC:

  • Type in a Dos Prompt: powercfg -devicequery wake_armed
C:\WINDOWS\system32>powercfg -devicequery wake_armed
Logitech HID-compliant Unifying keyboard
HID-compliant mouse
HID Keyboard Device
HID Keyboard Device (001)
Logitech HID-compliant Unifying Mouse
Intel(R) Ethernet Connection (2) I219-V
Logitech HID-compliant Unifying Mouse (001)

The PC can also be waked up by Timers (Scheduled Tasks):

  • Type in a Dos Prompt: powercfg -waketimers
  • Open the “Task Scheduler” and find the task mentioned by the command above.
  • In the tab “Conditions” of that task, disable the option “Wake the computer to run this task”

You call also disable all tasks that could wake up the PC at once:

  • Open the “Power Options” > “Change plan settings” > “Change advanced power settings”. Under “Sleep”, disable “Allow wake Timers”

Finally, you could also have to disable the Automatic Maintenance:

  • Open “Change Automatic Maintenance settings” and disable “Allow scheduled maintenance to wake up my computer at the scheduled time”

Tips Cannot access my NAS from Internet Since I have enabled Wifi on my modem

I just discovered that I was not able to access my NAS anymore from internet. The problem was that I did re-enabled the Wifi by accident on my Vdsl modem.

Click to Read More

Tthe DHCP server gave unfortunately the first free IP of the IPv4 pool to “an unknown Wifi device” instead of assigning this IP to my router as it used to be the case in the past. Port Forwarding from internet to my router, defined using that first IP, couldn’t work anymore.

I just did assign a static IP to my router in the Vdsl modem’s DHCP server settings (and re-disabled the WiFi). I did reboot next the router.

SynologyTips Synology’s Could Sync Consuming Internet Quota With Google Drive

I noticed that between 50GB and 100Gb of my Internet Quota was consumed per day since two weeks. After investigation, I found it was due to the Cloud Sync service of my Synology Nas “looping” infinitely.

Click to Read More

The first step was to identify the device downloading some many Gb per day.

I did enable the logging service on my router and turn on the logging of its firewall for all outgoing connections.

I did export the log of the firewall into notepad++, cleaned up a bit the log to keep the source and destination IP only.

I did copy that into Excel and created a pivot table to see which source was doing many connection and onto which external IP (eliminating known destinations as the DNS of google 8.8.8.8 and 8.8.4.4, the Synology’s KeepAlive service 118.163.30.162, Broadcast 192.168.0.255, …) I saw that most connections were onto 172.217.16.193, 172.217.21.202, 172.217.22.42, … from my NAS.

Using a IP who IS service, I found that 172.217 belongs to Google. Why was my NAS connection to Google ? I did look all the packages installed on my NAS and “tilt”: Cloud Sync was configured to sync two google accounts… Having a quick look into the current status of Cloud Sync, I noticed it was “syncing” 1 file… apparently for ever.

I did connect on my NAS via Telnet and looked into /var/log/cloudsync/daemon.log

In there, I found that cloud sync was logging, in a loop, errors like:

Dec 10 11:19:26 [ERROR] gd-pull-event-by-list-handler.cpp(89): ListDirectory: ListRemoteSubitems failed (retrying) [-1000] User rate limit exceeded

Dec 10 11:19:26 [ERROR] gd-transport.cpp(2196): error message: [Rate Limit Exceeded].
Dec 10 11:19:26 [ERROR] gd-transport.cpp(2238): Hit rate limitation.

I will look into a solution to this issue and temporarily unlinked the Google Drive account from Coud Sync…

voilà voilà.
