While trying to automate SSL certificate deployment for haproxy I had some trouble while doing test-runs (because for certbot –dry-run another account is being used). As I couldn’t find a direct way to list all accounts, here’s how to achieve that anyway (with some extra work). By default certbot show_account lists my official API account: […]
I’m planing to install eduvpn as a personal VPN solution. I also want to separate the VPN functionality (“vpn-daemon”, hostname “eduvpn-node”) from the management web frontend (controller or “vpn-user-portal”, hostname “eduvpn”). Adding software repository So we start by configuring the required software repos (on both machines, here’s the new APT822 version): Basic installation After that […]
While it gets more and more common to integrate letsencrypt certificates (and their automated roll-out) into products, there’s plenty of devices out there, that require manual installation of SSL certificates. As the time for valid certificates gets reduced more and more (and letsencrypt uses quite a short lifetime anyway) it’s nice to have some kind […]
While trying to do SSL off-loading/termination using haproxy for some test instances I was looking for a solution to handle certificates from letsencrypt (via certbot) with haproxy (and no separate webserver, neither the built-in one of certbot nor any apache/nginx/…). And there really is a solution for this! A more detailed post about how to […]
While upgrading to Ubuntu 24.04 some of the sources.list files were (automatically) converted to the new APT822 standard. However others were left untouched (or deactivated). For all of you out there, here are some of my findings while doing the file conversion: Let’s take the docker repo as an example (original description here): Make sure […]
After upgrading my Ubuntu 22.04 installation to Ubuntu 24.04.1 (using do-release-upgrade) my NFS exports stopped working. Kernel 6.8.0-41 reported an OOPS as soon as the NFS share was accessed (using sec=krb5b on the NFS client): Looking for a similar bug I found one on the NFS kernel mailing list titled “[PATCH] SUNRPC: Fix loop termination […]
…or to be exact: the Samba version of it 🙂 So as an Open Source guy I obviously don’t run a Microsoft Active Directory. However since Samba version 4 this software does not only support file and print services, it also can act as an Active Directory. And guess what: That’s what I do. Unfortunately […]
If you want to use Keycloak as IdP for your SAML login you might wish to limit access to certain Service Providers (SPs) according to your LDAP group memberships. The way to do this is not very intuitive, so I’ll try to show an easy way to do this. What we’ll be doing: Step 1: […]
This short post is about how to run the open-webui docker container with an apache based reversed proxy (handling the SSL termination and authentication with mod-auth-mellon). In the following example the open-webui docker container is listening on localhost only, port 8009 (s. variable definition at the beginning of the apache2 config): In order to use […]
While playing around with Apache web server authentication I was wondering: Is it possible to authenticate Apache against LDAP without requiring a proxy account to do the queries? At first glance this seems to require an LDAP server that allows anonymous bind and read access, however there’s another way: If a regular user (of the […]
