OpenVPN AddOn

I will be working on a rebuild of the user interface soon for the OpenVPN AddOn, and I will add the config file option back when I do that. I will take a look at the TCP/UDP issue later today and report what I find.

SoftChip,

Are you setting the protocol globally or in the host config dialog? Just wondering because it's writing the config fine, but I wonder if we're running into some default/overridden behavior of OpenVPN because of the connection tags the hosts are wrapped in.

Hi, jskuby.

I'm also having this problem, and interested in it being fixed. In my situation, I am importing an existing and working .opvn config file into the host configuration dialog. Everything looks correct, but when connecting, the displayed connection text shows it is attempting the link with UDP.

Thanks for your help/efforts. It is greatly appreciated.

I believe I have fixed the protocol issue. Can you try this build? I'll be (re)adding the config selection this weekend.

OpenVPNAddOn 1.1.0.3

Hi jskuby,

sorry, I've been out of office.

First: This is a great AddOn, I already had the idea myself, but now I don't have to do this, you just did it! Thank you!

I don't know where I can set the protocol globally, i cannot find settings for you AddOn. But the new version works fine, now it uses TCP as protocol. Great work.

I have one connectionfile which uses a .p12 as "pkcs12" but this is written into "Additional Parameters". Is there any ability to use this files?

I have one more question: If I want to use more than one connection at one time, the open-vpn-gui doen't allow this. Is there the ability to user openvpn directly, without using the gui?

When I said globally, I probably misspoke. I should have said in the main OpenVPN AddOn session config (not in the host), but it's good to know 1.1.0.3 fixed the issue. I should be able to add the pkcs12 support this weekend while I'm working on the other tweaks/features. I'll also look into opening multiple connections via the command line and possibly putting a tray icon while it's connected, so there's some indication other than in RDM that the connection is active.

Version 1.1.0.3 worked perfectly for me. Both my tcp and udp connections work correctly now. Thank you!

Hi jskuby,

thar would be great.
I also tried to use the gui to open more than one connection but I always get the errormesasge that the gui has already been started. So I think you have to use openvpn directly without the gui.

But have a try ;)

Hi,

I've been trying to get this addon to work as I currently use OpenVPN to connect to most of my clients before I RDP to server etc. I cannot seen to get the config to work though I keep getting the following error trace

I'm using RDM 5.7.1.0 Enterprise with the OpenVPN AddOn 1.1.02

Hello rkentish,

I'm sorry to hear you're having issues. At what point are you getting the error? Are you manually entering a connection or using the import option? Could you try the latest version, which is 1.1.0.4, and let me know if you still have the issue?

You can get the latest version at my site:
http://www.pocketemu.com/rdmaddons/openvpn-for-rdm/

Have just updated to 1.1.0.4 and I'm still having the same problem.

The error occurs when I actually try and to connect the session. I have been creating the OpenVPN config manually. Does the addon create the config and cert files on the fly (from the database options) and if so is there somewhere I can check to see if they are being created properly?

BTW Thanks for the quick reply
edited by rkentish on 3/16/2010

Yes the connection is created in the RDM user data folder, which should be:
Vista/Win7 - C:\Users\<username>\AppData\Local\Devolutions\RemoteDesktopManager\OpenVPN
XP - C:\Documents and Settings\<username>\Local Settings\Application Data\Devolutions\RemoteDesktopManager\OpenVPN

There should be a folder in there with the config files that are generated when launching the connection. There are only a few spots in the addon where I use FileInfo, so this shouldn't be too difficult to track down.

I may have tracked the issue down. Can you please try this build and let me know your results?

http://www.pocketemu.com/downloads/OpenVPNAddOn_1.1.0.5.zip

That build worked great!! Thanks for you're help and excellent response times.

I just have one last question, is there any way to specify a delay before trying to connect the session (or can it wait for a success response from OpenVPN). The RDP session that runs over the VPN is attempting to connect before the VPN is established and then timing out as the VPN takes a couple of seconds to establish.

Glad to hear that worked for you. I'll release that version tonight because that's a pretty major issue you found. Thanks for reporting it.

I will be implementing a wait time soon, but in the meantime there is a way to have it work. Set up the OpenVPN connection as it's own session in RDM, then in your RDP session's VPN tab select "Existing Session" and point it at the OpenVPN session. The "Existing Session" option has a wait time implemented and it works well with the OpenVPN AddOn.

Sweet, that will actually work better for me as I have 3 - 4 different internal machines that I need to get through via the same VPN connection.

Do you know if the VPN session will be held open as long as one of the sessions is using it (if I set the auto disconnect option)?

If you use the the "connect if unable to ping" option, and the machine you're trying to hit (or just testing for ping) is pingable via the OpenVPN connection, things should work just fine because in order to ping the machine the tunnel has to be up and running.

Hi,

I think rkentish wants to know if the OpenVPn-Connection is left open if mote than one Remotesessions are using it.

As far as I know this is not possible, but in planning.

Exactly, this is something I want to add in the next major update and maybe before. I really think that it's an important feature but it's not simple (not too complex too) to implements. For the next minor update, I could add an option to "ask confirmation before closing VPN". At least you will be able cancel the close.



What do you think ?
edited by dhervieux on 3/18/2010

I think that will be enough.

In the interim I think that would be great as during testing/playing yesterday and last night I was having problems with the connection closing on me after one of the sessions ended.

Another problem that I was having was that my OpenVPN connections were taking a long time to come up and it meant that I was continually increasing the wait time.

Is it possible (this may be something that has to be implemented in RDM) to not report the connection fully up until the server at the other end can be pinged and to implement a dynamic wait for the depending session. Eg. The RDP session will not attempt to connect until it either gets a "successful" from the VPN connection or it can actually ping the host it is trying to connect to?

Good idea, I added a feature request for that

Is there any progress on the "proxy problem" like discribed below?

There seems to be a problem when using the http proxy. When connecting the proxy uses the remote server port instead of the http proxy port.

Hi,
I'm not sure, I understand what is the proxy problem port, can you reexplain the problem

I enter a proxy configuration (http adres and port)

When I try to connect it uses the proxy http adres, but not the proxy http port of the proxy server, but it uses the server port (default 1194) instead

Hello BART_666,




I had taken a break from working on the addons for a while (real life got in the way), but I'm back to a point where I can resume work again. I'll get this on my TODO list.

I have a new version to test out before I take it live. This should fix the http proxy problem, and I've also added support for the PKCS12 certificate store, in addition to the default individual cert and key files. I'm also in the process of reworking the GUI a bit. Let me know what you all think and how it's working for you:

Hi,

It seems to work fine! Thx
Only the automatic entering of the username and password is not always entered. (i do not press any key)
Is there may be a workaround?

This addOn no longer works with the latest version of RDM 5.8.3.0

Hi,
What error do you get ?

I don't get an error, It just doesn't appear.
I had it working with the previous version, after the upgrade the openvpn option is no longer available under VPN.

I have reinstalled on a new machine, unzipped the latest OpenVPNAddOn.dll v 1.1.0.6 into the program folder and still it doesn't appear under Vpn..

I suspect that there is a problem with the Program files virtualization. Can you try to move your installation in another folder, for example c:\RDM ?

Also,
if you try this beta version,

http://remotedesktopmanager.com/download/Setup.RemoteDesktopManager.5.8.3.5.exe

You can install the dll at the same place than the application. You can find the path by using the menu Help->View Applications Log
edited by dhervieux on 10/8/2010

yep, your right.
Moved it to c:\RDM as you suggested and now it works.

Beta version in your link also works in C:\program files\....
Thanks

The problem with the beta version now though is I can't change the location of the data source.
No Popup appears.

Hi,
I posted the wrong url:

http://remotedesktopmanager.com/download/Setup.RemoteDesktopManager.5.8.3.5.exe

When I connect with the latest release of OpenVPN and RDM to an OpenVPN connection that requires the OpenVPN GUI to be run with Administrative rights (Windows 7 64-bit with UAC enabled), it only connects when RDM is started with Admin rights as well. Any way to have RDM request that OpenVPN be started with admin rights without starting RDM with admin rights? I haven't used OpenVPN with RDM before now; I assume this isn't a new issue though. No elevation required with Shrew and IPsec, but I assume that's because IPsec requires a kernel driver to already be installed and OpenVPN runs in userspace but needs privileges to be able to flush the arp table and update routes.

Hi,

OpenVPN 1.1.0.6 and latest RDM 5.9.0.0a (but saw this also in previsus versions of RDM) does not fill key password even this is set in option page of vpn connection.
seems the same as BART_666 reported 9/7/2010.
is anybody facing same problem or is teher any solution for this problem?

Hi

i cant download that file the site is not reachable.

Can u post it here or post a new link please

Thanks

Henning

Hi,
It's available now directly from our web site:

http://remotedesktopmanager.com/remotedesktopmanager/Home.aspx/AddOn

OpenVPN 1.1.0.6 and latest RDM 6.0.0.0 does not fill key password even this is set in option page of vpn connection.
is anybody facing same problem or is teher any solution for this problem?

Thanks

Hi,
I'm not the one that did this add-on but I took a look. I simulate the SendKey for the authentication. I suppose that you are prompted but it's not filled? Can you try to run the application in Administrator mode?

In the new versions the "Set Authentication" is not working. It is possible to change the username, but after changing the password and saving, the new password is lost.
Also the checkbox "show password" does not work.

Is it possible to fix this?

Hi,
I will take a look at this. Thank you

Hi there. Were this problem been fixed already?

No, this is not fixed yet. dhervieux?

I have assigned this to Andre

Hi,
Could you try this new version please?
I added the "Credential repository" support and fixed the "Show password" in 2 forms.

Regards

It works super! Thanks!!!

hello

if i try to import .opvn file whitch contains .crt or .key file with space in name this configuration is not possible to import ...
in .opvn configuration file this is enclosed in quotes but it seems the whole path is also enlosed in quotes, so it try to read something like this:
"C:\Program Files (x86)\OpenVPN\config\"file with space.crt""

Hi,
Could you try this new version please ?
I think that the filename issue is fixed.
Regards

nope :(

Hi,
Just in case you missed the update of my last message.
You may send the file to infos@devolutions.net

hello andree

sent to infos@devolutions.net ...

Hi,
This one should be better :)

hello andre

confirmen that import works, but if i try to use it it fails, because when you generate own .opvn file, ca, cert and key parameters is NOT enclosed in quotes, so openvpn did not find them

Hi,
I added quotes to filenames in generated ovpn file.
I hope that will solve your issue. I don't have the appropriate setting here to test it.

hello andre

confirmed all is working now

Hi guys,

Not sure if this is a bug or I'm improperly configuring OpenVPN. I've setup a new VPN and configured the option "Enable automatic key password entry" and specified my password.

If I run OpenVPN it says it connects OK but it does not actually add the routes (error: the requested operation requires elevation).

The workaround I have previously used when seeing this is to configure the openvpn-gui executable to run as administrator (2.jpg), however if I do this I am prompted for the password again (if I correctly type it the VPN works).

I'm using Windows 8 x64, can someone replicate this issue?

Thanks,
Dragos

Hi, just wanted to let you know I solved this issue by having RemoteDesktopManager.exe run with Administrative privilege level.
