A technical blog about HCL Connections, HCL Domino and other stuff
With the introduction of CertMgr in Domino 12, it became very easy to request a LetsEncrypt certificate for your Domino servers. But the standard HTTP-01 challenge, comes with limitations. DNS-01 challenges are far more powerful, but require extra work. In a series of blog articles, of which this the 1st, I’ll explain how to use DNS Configurations.
Continue readingI regularly receive question about the Certificate Store and CertMgr, which made me realise that there’s a lot of confusion around the Submit Request and the Save & Close buttons in the store and when to use what. Time for an article to hopefully solve some of that confusion.
Continue readingHCL renamed a server task in Domino 11. RepairCleanup is now called RprCleanup. If you’re not aware of this, you might get confused.
Continue readingI had an interesting problem with HCL Traveler recently. It should be a very rare problem, but if your Traveler seems ok on the Domino side, but the url just gives an error 500 and the Traveler logs give error CLFAD0211E and/or CLFAD0246E, then this blog might save you a lot of time
Continue readingThe new Certificate Manager of Domino 12 has made it extremely easy to deal with TLS Certificates. Also when working with certificate authorities that use a web portal. However, some administrators still use old pre-12 procedures to request certificates. I’ve described in this article the proper way to do this in Domino 12.
Continue readingDomino 12.0 has reached GA and is available on FlexNet now. More than in time for the big launch event on the 7th of June. Notes & Domino 12 is an exciting new version that brings great new features both under the hood and, very visible, in the Notes client!
Continue readingIn the past years we saw less and less backup solutions which supported HCL Domino and specifically supported Domino’s transactional logs. HCL needed to step in to solve this and they did. This post shows how I combined Domino 12’s new Backup solution with Borg backup, an open source backup solution, to create a perfect Backup solution for Domino.
Continue readingIn my previous post I looked at the performance of the Domino V12 HTTP task in decrypting/encrypting SSL traffic. One of my biggest findings was the huge influence of the elliptic curves on the performance. In this post I dive deeper in the differences between the various curves and compare Domino 12’s best to Domino 11’s best.
Continue readingFor years, many of us have placed reverse proxy servers in front of HCL Domino for 2 reasons:
– Domino didn’t support either SNI nor the latest ciphers
– Domino’s SSL performance was really bad
In my previous article I described how HCL solved the 1st problem with the new Certificate Manager in Domino 12. Now I look at the 2nd reason. SSL performance.
Continue readingHCL Domino V12 is in beta, and we currently have beta 2 to work with. One of the interesting new features of Domino V12 is the Certificate Manager task (certmgr). I’ve been playing around with this task and in this post I’ll tell about my experiences.
Continue readingThis is a collection of things I encountered during my work and were interesting enough to write down. Both for myself and for others. Topics include HCL Connections, HCL Domino, Linux, SQL etc.
