Synology NAS DSM Connection

[angryhippy]

Does anyone know how to get connected via the OpenVPN client in Synology's DSM software that comes on their NAS products? It seems straightforward, but fails for me with "Authorization Required".

The only options I have are these:

We put this question to one of our dev team heavyweights, who has perhaps been spending a bit too much time lately working on deepDNS & webRTC to be presentable in civilised company just yet. His reply, verbatim:

my advice with any NAS is to root the bitch and use OpenVPN like a normal hakkar :E

Sooo... we'll put this to the tech support folks & see if they are a bit more constructive; more information to be posted here shortly.

@cryptostorm_team

That sounds like df.

That's what I figured, but if someone had an easy way to force DSM to submit, I was gonna go that way

[Raka74]

I actually got this working FYI , don't know if completely correct but:

create a VPN connection choosing OpenVPN as follows:

https://www.dropbox.com/s/r800c4b68gige ... .png?dl=0#

Use the based token as username , something random as password (not sure if token is needed as this is configured later ) and the .crt as provided in this forum

After that ssh into the Synology and go to /usr/syno/etc/synovpnclient/openvpn

vi the client_xxxxx file and delete all lines in there.

paste the contents of the crypto storm-linux conf file u want to use in the client_xxxx file

go to the line that says auth-user-pass and put pass.txt behind this

https://www.dropbox.com/s/4iz3an8by9bhm ... 2.png?dl=0

save the file

vi a new file named pass.txt

on the first line paste the hashed token
on the second line some random password.

save the file


https://www.dropbox.com/s/rrym8hnhzf135 ... 6.png?dl=0

So I was following Raka74's steps above and wrestling with getting this working myself last night and finally ended up getting it to work and learned a few things along the way that I thought I would share for anyone attempting the same thing.

When creating an OpenVPN connection on the Synology it doesn't really matter what details you enter into the fields provided as you will be overwriting them anyway when you SSH into your NAS and replace the config in the client_XXXXXXXXXXX file in the following step. SSL cert included.

Also note that as soon as you use the WebGUI to edit your OpenVPN config you will lose all the required cryptos tom settings you have previously edited and saved in your SSH session and you will have to edit the client_XXXXXXXXXXX file again. (I got caught out by this in my attempts at troubleshooting my non-working connection.

When SSHing in, I had to make sure I was doing so as 'root' or else I didn't have the required permissions to create the pass.txt file.

FWIW, for my working OpenVPN connection I copy/pasted the contents of this config file but you should be able to use any from this page.

Hello!
This thread seems a bit old but it is exactly what I was searching for.
I'm planning to subscribe for one year but I wanted first to have a look how to make my Synology NAS connected to the vpn.
the link to .png file is no more valid in the post above. And to be honnest, I'm not used to SSH... I'll try if it is necessary but before I want to try the .ovpn file config that Synology propose in the NAS settings.
I was wondering which .ovpn file I should download from GitHub?
Any idea?
If it is not possible, I would like to know on which line I have to put "pass.txt" in the client_xxxx file (.png no more available in Raka74 post)
Thanks for your help!

@poupee

Use the config files in the Linux directory on GitHub.

[poupe]

Thank you for your answer!
I have tried but I can't manage to get it work.
I have follow the synology settings for openvpn with .ovpn file which are very basic:
-user name: the tocken hash generated
-passwd: anything
- I have imported the ovpn file (cstorm_linux-paris_udp.ovpn) and the ca.crt from Github, as requested in the Synology settings.

It doesn't want to connect, saying "authorisation required".
I am missing something?
thanks for your help!

@poupee

Does "authorisation required" come up immediately or after it tries to connect? Can you post any logs? If after, it could be that it is receiving AUTH_FAILED from the exit node. If that's the case, check your token at the token checker in my sig.

It could be that either a) the token hash is incorrect (there's a space at either end) or b your token has hit its session limit.

If you have a Linux machine, you could enter this in a terminal:

Code: Select all

echo -n <token> | sha512sum

This will give you a valid hash.

[poupe]

"Authorisation required" alert comes about 10sec after trying to connect. It is not immediate.
DSM synology does not allow me to have a space before or after the hash in the vpn settings. I just copy/paste the hash from the calculator.
I have no other devices using this token. So I should not have session limit.
I'll post the logs later tonight as I'm not home. (well, I'l try to find where it is as I never needed it before).
last, sorry I have not a linux machine.
My question for the moment is: should I try to edit the config file via ssh as shown by Raka74 in this post and creat/add the pass.txt file?
I have not done it because I thought that it was a bit different than what Raka74 did, as I have already import the config file with the .ovpn file importation in Synology.
But if you advice me to do so, where should I had the pass.txt in the config file? Raka74 said "go to the line that says auth-user-pass and put pass.txt behind this". It's not clear to me (.png link Raka74 posted is no more available).
THX for you patience!

Parityboy said: check your token at the token checker in my sig.

Could you explain me how to do this?
Sorry...!

Click on the token checker link and then in the input box paste in your token. It will tell you if the token is valid.
