OpenVPN “auth-user-pass-verify” doesn't provide password
December 29, 2011
I was trying to using OpenVPN’s auth-user-pass-verify option, which allows you to essentially build your own authentication mechanism for usernames/passwords. I had a very, very simply authentication script setup and was using the “via-env” method. I fought for at least an hour or two trying to figure out why my passwords weren’t being accepted, even when I changed the password down to being as simple as “a”. Turns out I was doing everything right, but getting shafted.
OpenVPN on Vista 64bit (And Windows 7!)
June 15, 2009
At our office we use OpenVPN for our VPN needs. This was a change I made a few years back, taking us away from Windows PPTP. It has proved to be an interesting experience, because things do not always “work” on the client side. This is most apparent when dealing with Windows and/or 64-bit computers. It becomes even more fun when the boss wants OpenVPN on his Vista 64 machine. Up until recently it simply wasn’t possible because there were no compiled 64-bit versions.
Embassy Security Center does NOT play nicely with OpenVPN
July 2, 2008
So I was just re-installing a machine (Windows XP SP3 x32) in the office and I got to the point of setting up the OpenVPN connection (so I was almost done). Problem was that when I installed OpenVPN 2.0.9 and executed the EXE, it crashed with “The application failed to initialize properly (0xc000007b).". I tried uninstalling and re-installing OpenVPN. When that didn’t work, I then tried upgrading to OpenVPN 2.1 RC_7.
How To Get OpenVPN to Work Under Vista
September 20, 2007
Getting OpenVPN to run under Windows Vista is actually relatively easy. There are just a few tricks to keep in mind. Get the latest version of OpenVPN. 2.0.9 works for me, 2.0.7 did not If you still have UAC enabled (It is those “Accept/Deny” dialog boxes), you must right click on the installer and “Run As Administrator”. (How to disable UAC) During the install, you must remember to “Continue Anyways” when prompted about unsigned drivers.
To Vista, Or not to Vista?
December 1, 2006
No, this is not an “internal” debate being externalized just so I can post. I install Vista, weeks ago. In fact I installed it Nov 17th, the day it was released to MSDN (Along with Office 2007 which I installed). This is a quick “review” for those debating on installing. Short Review: DON’T DO IT. Long Version: At this point in time, if you are a casual user, Vista is fine. The User Access Control system is a pain and will quickly teach you to click “Yes” to everything (Which is bad). There aren’t many drivers out (read: near none), but if your not playing any games or have any fancy hardware, you’ll be ok. The graphics are nice, with the transparency and all (if your computer can support them, and you buy the “right” version of Vista with Areo) but they are just eye candy and really aren’t that handy. Now… If you are a power user. For the love of god, save yourself the trouble and don’t install Vista. I waited very very patiently for Vista to be released to MSDN when I heard it hit RTM (read: I was bitching and moaning about MS not releasing it sooner), but now I realize thats a mistake. As I said previously, there are next to no drivers out. I managed to get new graphics drivers installed on my Dell Latitude D620 (with a Quadro NVS 110M) thanks to a hacked nVidia driver from LaptopVideo2Go. It shows up as a 7300, but it works fine, enough. I didn’t really need to install drivers for anything else, which is good because nothing is out. Some of you that switched early from Win 2000 to XP may remember that you could use just about every 2K driver on XP, well thats definitely not the case for Vista. Any driver you install that wasn’t re-worked for Vista will either be blocked from install, muck up your machine, or plain not work. Also, any software thats reasonably advanced, is hardware related, or makes a decent amount of changed to your system probably won’t work. Again, this is a problem for Power Users such as myself. Now I’m not saying never run vista (though the login & shutdown times are KILLER for me), I’m just suggesting you wait… a few months. Probably at least 6 months after the public release. Now, After the break (yes, I’m actually writing into the “extended body”) I’ll run down software I installed and how well it worked (and if I used the emulation).
OpenVPN & Vista
September 22, 2006
I was alerted (by a blog comment) that someone has fixed OpenVPN & Vista. No more BSOD’s. You can check the mail archive item for yourself. Or see the forum post. I haven’t tested it personally, as I’m no longer running Vista, but if anyone else is — let me know if it works for you.
The Virtues of OpenVPN – Part 3
August 29, 2006
Yesterday I wrote about how to get a Windows client up on OpenVPN via service. But what if you want to deploy a number of these and don’t want to write up 10 page “HOWTO Install” docs? Well, that is exactly what I thought, so I automated the proccess. Here’s what I did: Put together a directory with: ca.crt client.crt client.key COMPANY.ovpn openvpn-2.0.07-install.exe vpn.bat network.txt — (Actually VBS File) service.
The Virtues of OpenVPN – Part 2
August 28, 2006
If your like me coming from the PPTP frame of mind, you only dialed the OpenVPN connection on the clients when it was needed. This is good, but OpenVPN includes its own service which makes it all the more awesome. As soon as you client machine starts (in this case windows) so does OpenVPN (if you set to to start Automatically). This is really nice because as long as there is a network connection, OVPN works without an issue (so far that I’ve seen).
The Virtues of OpenVPN – Part 1
August 25, 2006
Ah, I have discovered the wonderful warm and fuzzy feeling that is OpenVPN. Now its not that I’ve never heard of OpenVPN before, I just never really got around to using it. The oddest piece of OVPN is that there is no “server” or “client” software. They have a single piece of software that simply acts different depending on the configuration file (and seeing is how you can have multiple config files, you can actually have a server and a client operating on the same machine, using the same binaries).
OpenVPN & Vista
August 23, 2006
Dont. No, really, I’m serious. Don’t bother installing OpenVPN on Windows Vista. It just doesn’t work. Apparently as soon as it gets to installing the network drivers, Vista goes down HARD (Blue screen). Which interestingly enough, is the first time I’ve seen vista crash (though it has frozen a few times). If your wondering, I used 2.0.7. But I’ve heard others have had the same issue.
