 Two Factor U2F added

Portknox u2f auth

Its now possible to activate Two Factor Authentication with U2F devices like the Yubikey. Another way to further secure you cloud. Please read documentation before app activation.

Tasks updated to 0.9.5

This minor update fixes some bugs with Nextcloud 11. Here is the full changelog.

Two Factor TOTP updated to 1.1.0

Polishing and some minor fixes. Here is the full changelog.

Please note that we update customer clouds in batches, if your cloud does not have the new apps yet, give us some more days :)

Nextcloud update 11.0.2

We are happy that all customer clouds have been updated to Nextcloud 11. At Portknox every single customer has his or her own installation (with own domain / url) which is much safer than only having an account in a big shared instance (which is what most of the other providers do). Even if keeping all of the clouds up-to-date takes more effort - it's worth it! The Nextcloud security scan rates Portknox clouds with A+, the highest score achievable:


Always up2date applist

At our applist you can see which app in which version is installed on Portknox. We now automated the way our applist is generated, after every Nextcloud or app update the list gets regenerated. Right now its possible to activate 36 apps!

ownCloud, Nextcloud and the hosting provider

2 min read


As many of you have already noticed, Frank Karlitschek has started a fork of ownCloud called Nextcloud and started bootstraping a new firm around it - the Nextcloud GmbH.

Many customers have asked us what this means for - the hosting provider and partner. Actually, we have not decided yet whether to stay with ownCloud or switch to Nextcloud and we will take the time it needs to make the right decision.

Nextcloud is planned as a drop-in replacement, this means it is possible to migrate to it from ownCloud later on. Right now we will not change anything, instead we finish the migration of all customers to ownCloud 9, which is the perfect base for a switch to Nextcloud. But we will decide at some point as it does not make sense to support or ship two different cloud systems. We stay specialized, focused and up-to-date, to provide the best solution for our customers.

I am sure we will make the right decision, as I know most of the developers from ownCloud and Nextcloud personally. Furthermore we are deeply involved and follow the progress of both projects.

Let's see what happens and hope competition is a good thing!

How to manage todo.txt with ownCloud

2 min read

Because it's so flawless and easy to setup I want to share my Todo.txt & ownCloud setup I use every day.

Todo.txt is task tracking in a simple txt file you control. A set of simple rules help you get organized and there are several apps for all kind of devices.

Because no one should know what I want to do next or what I have done, it's important for me to host myself. The official Todo.txt apps for iOS and Android are no option, they only work with dropbox.

So here is how I host my own Todo.txt in ownCloud and how I keep it in sync with all of my devices:

On my workstation and laptop (which run with Linux), I use the Todo.txt Command Line tool, for me it's the fastest and most effective way. The ownCloud Sync-Clients do the hard work and keep the files up-to-date:


This just works, never had a conflict or outdated files. Configured one time and ready to work.

On my Android Phone I use FolderSync Lite together with Simpletask Cloudless. I choose FolderSync over the ownCloud Android Clients because it does not use that much battery (maybe it's better now). I use scheduling of 2 h which works good for me, on my phone I don’t need instant sync.

Simpletask Cloudless accesses just the todo.txt on your phone (synced by FolderSync):


Because todo.txt is just a plain text file, it can also be easily managed within ownCloud web interface and the texteditor app.

Now Get Things Done!

Further improvements to HTTPS encryption for PortKnox clouds

1 min read

Improving the infrastructure and increasing the security for PortKnox and the hosted clouds is an ongoing task. The last days we've accomplished another milestone. New customers will already get the best HTTPS encryption with a SSLab Rating of A+:

Portknox SSL Labs

Existing clouds will be migrated to the new setup during the next weeks, there will be no downtime or interruption. Advantages of the new setup are a faster response to vulnerability and updates. Furthermore, Forward Secrecy is now enabled, which makes it impossible to decrypt the HTTP transfer, even if the private key is stolen from our servers.

Please note that the Internet Explorer on Windows XP does not support this high security configuration. You should therefore update your system as soon as possible.
