![]() We do not recommend installing the Duo Authentication Proxy on the same Windows server that acts as your Active Directory domain controller or one with the Network Policy Server (NPS) role. See detailed Authentication Proxy operating system performance recommendations in the Duo Authentication Proxy Reference. Debian 7 or later (Debian 9+ recommended).Ubuntu 16.04 or later (Ubuntu 18.04+ recommended).Red Hat Enterprise Linux 7 or later (RHEL 8+ recommended).CentOS 7 or later (CentOS 8+ recommended).Windows Server 2012 or later (Server 2016+ recommended).The proxy supports these operating systems: If you will set up a new Duo server, locate (or set up) a system to host the Duo Authentication Proxy installation. However, there are some cases where it might make sense for you to deploy a new proxy server for a new application, like if you want to co-locate the Duo proxy with the application it will protect in the same data center. You don't have to set up a new Authentication Proxy server for each application you create. If you are already running a Duo Authentication Proxy server in your environment, you can use that existing host for additional applications, appending the new configuration sections to the current config. This Duo proxy server will receive incoming RADIUS requests from your Barracuda SSL VPN, contact your existing local LDAP/AD or RADIUS server to perform primary authentication, and then contact Duo's cloud service for secondary authentication. To integrate Duo with your Barracuda SSL VPN, you will need to install a local Duo proxy service on a machine within your network. You should already have a working primary authentication configuration for your Barracuda SSL VPN users before you begin to deploy Duo. First Stepsīefore moving on to the deployment steps, it's a good idea to familiarize yourself with Duo administration concepts and features like options for applications, available methods for enrolling Duo users, and Duo policy settings and how to apply them. If your organization requires IP-based rules, please review this Duo KB article. Firewall configurations that restrict outbound access to Duo's service with rules using destination IP addresses or IP address ranges aren't recommended, since these may change over time to maintain our service's high availability. None of my variables have the shared prefix, nor do I use the third kernel launch argument.This application communicates with Duo's service on TCP port 443. Therefore, I dug a little deeper and noticed that the error (0x2) might be because of shared memory requirement, but haven’t found any way I can determine how much does my kernel use. I find it hard to believe our kernel managed to gobble up nearly a GB worth of space. The following line fails never reaching the first lines of code inside the kernel:ĬalculationKernell>( arrLen, arr, kernelData, results, log) The point where the code fails is upon entry to the kernel itself, not within it.Outside of processing, the changes affected the pre-allocated memory and added one statically-defined boolean inside the kernel. The system worked prior to a few changes.All memory for the kernel is pre-allocated before the call.The error persists even when the amount of free memory, per cudaMemGetInfo, is up to 900mb. ![]() I’m not at liberty to post the contents of the program, and it is very long. Warning: Cuda API error detected: cudaLaunch returned (0x2)Īccording to the documentation, Error 0x2 means the API call failed because it was unable to allocate enough memory to perform the requested operation. When debugging, I also see the following error: Now, I have no idea how it got name for the kernel but that seems besides the point. When attempting to run a kernel from host, we get this:ĬUDA error while running kernel: /home/Velo/History/2013/.dat, err: out of memory I’ve searched for similar problems, but no suggestion seemed to help. I’ve encountered something weird, and am unsure whether it is a bug, misuse of the hardware or just a misunderstanding.
