I have already discussed Heartbleed in detail and have provided instructions on how to close the hole on affected server. Now that the hole is closed the final step is changing your server’s private key and “re-keying” your SSL certificates. Re-keying simply involves creating a new certificate signing request and sending it to your (most […]

Recently we had to wrestle with the Heartbleed bug. Heartbleed, was/is a major flaw in certain versions of OpenSSL, which is itself an “open source” project/application/codebase… This has had all of the armchair developers (myself included in that mix) either defending the concept of open-development or attacking it on grounds that it is less secure. […]

Heartbleed was a major vulnerability in the SSL protocol used by many many sites and services. Folks have been scrambling to patch it up quickly since it was announced a few days prior. If you are in the process of doing just that for yourself or your organization, you might be so busy fixing websites […]

The Heartbleed bug is what I would professionally classify as seriously scary stuff. Basically there is some kind of heartbeat functionality built into OpenSSL. Often, in tech talk, this kind of thing is used for remote service monitoring (i.e. if I have a pulse my service is at least up). In this case, I am […]

Thought I would post this one quickly… Having trouble getting OpenVPN to start/work for you and you are seeing this error in your logs? “TCP/UDP: Socket bind failed on local address” The resolution is pretty simple. Try changing the port you have assigned to openVPN in your config file and restarting the service. Most likely […]

I am not sure when OpenVPN added multi-factor support to their Access Server but I am thrilled that they did. It must have been recently (within the last few weeks or months) as I was using OpenVPN Access Server about 4 months ago as a temporary solution while my main solution was down and it […]

After having already gotten a full page into writing a walkthrough (not to mention hours already spent with Authy) I found out that Authy will NOT WORK with OpenVPN and LDAP authentication unless the folks at Authy customize the ldap module for you. Which requires enterprise support, at a retail price of $500/month! Which was […]

INTRODUCTION I wrestled with getting OpenVPN to work with Microsoft Active Directory authentication better part of 2 days. I was surprised that it was so hard to find a straightfoward tutorial on the topic that actually worked! I had to do a lot of Google-Fu and look at many different pages to put together what […]
