Prerequisite: If you do not have a static IP, enable and set the DDNS on the SYNOLOGY NAS.
SETTING THE SYNOLOGY
- Install the package [VPN Server] in the Synology NAS.
- In my opinion (and for my needs) it's better to create only one VPN user and give the permision to fruition the VPN enviroment only to him. It's better that the password is very complex.
- Run it. In the left, from the group [Set up VPN Server], select [OpenVPN].
- Put a tick in [Enable OpenVPN server].
- Change the range of the Dinamic IP, if needed.
- Take note of the port "1194" and the protocol "UPD": it will be needed for setting the port forwarding in the Firewall.
- Click on [Export configuration] to have a zip archive content the certificate [ca.crt] and the configurations [VPNConfig.ovpn]
SETTING THE FIREWALL
Setting the firewall that's connected to the NAS, creating a rule with this parameter:
name VPN
protocol UPD
local IP address [the IP of the NAS, it's better to give him a static internal IP]
local port 1194
(or range 1194-1194)
WAN IP address ANY
WAN port 1194
(or range 1194-1194)
SETTING OPENVPN IN WINDOWS
From here, download OpenVPN and install it on the PC.
Run OpenVPN GUI as administrator.
Get VPNConfig.ovpn from the zip archive, edit it:
replace YOUR_SERVER_IP with the public IP of NAS or the hostname registered in the DDNS service of your NAS Synology
add those lines:
auth-user-pass auth.txt
route 0.0.0.0 0.0.0.0 vpn_gateway 500
Put it in C:\Program Files\OpenVPN\config
Ever in C:\Program Files\OpenVPN\config create a file named auth.txt
Edit it adding two lines: in the first one the user name created in Synology and in the second one its password.
CREATE AN AUTOMATIC TASK IN WINDOWS
Create a task in Task Scheduler with these rules:
At log on,
start C:\Program Files\OpenVPN\bin\openvpn-gui.exe
with those parameters --connect VPNConfig.ovpn
Prerequisite: Samba has to be installed and I suppose that the hostname of your PC is MyPC.
Create a directory in /media
sudo mkdir /media/DVD
Modify /etc/fstab by adding this line:
/dev/sr0 /media/DVD iso9660 defaults,noauto,ro,user,uid=1000,gid=1000 0 0
(one line)
Add (or check if it is already there) those lines in /etc/samba/smb.conf
[DVD-ROM]
path = /media/DVD
browseable = yes
read only = yes
guest ok = yes
locking = no
preexec = /bin/mount /media/DVD
postexec = /bin/umount /media/DVD
writable = no
Reread /etc/fstab
sudo mount -a
(ignore the errors that appears: it attempts to mount some already mounted devices)
Restart Samba
sudo service smbd restart
Put a DVD/CD into the drive and check the share:
in MAC
Finder > Go > Connect to Server...
type: smb://MyPC and press enter
Select Guest as user name
in Windows
Open the File Explorer
type \\MyPC and press enter
Scenario: You have installed W10 beside Linux (Ubuntu or Ubuntu based) but after this job, Grub disappear and you are not longer able to select the S.O. at the boot.
- Start with W10
- Open a DOS prompt with administrator privilege
- execute this command:
- bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
- Restart your computer with a live Ubuntu distribution
- Open a terminal (Ctrl Alt T)
- Regenerate Grub with this command:
With this command you can get a list of installed packages, order by size:
- dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}'
You can see which NVIDIA packages are installed on your pc, typing
and you can take note of the right package's name to uninstall.
It's not always recommended but you can use this command to remove it all in one shot:
- sudo apt-get autoremove nvidia*
Be careful, this is only a work around.
This feature is a part of usbcore which is compiled in the kernel.
From https://unix.stackexchange.com/a/175035.
- Edit
- Change
- GRUB_CMDLINE_LINUX_DEFAULT
- Add this option at the end
- That's the result
- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
- Save the file and update grub
- Reboot
Now, if you check the autosuspend value with
- cat /sys/module/usbcore/parameters/autosuspend
it should display -1.
