Security issue phuip-fpizdam does not effect Portknox clouds

1 min read

Nextcloud has published that there is a security issue within some Nextcloud configurations. We have immediately tested the published exploit on our infrastructure. All clouds on Portknox are safe.

We even have tested other Nextcloud providers and found out that they might be vulnerable. We have already informed all of them about the possible security risk.


We are at the Plone conference - support answers might take a little longer

1 min read

We are at the Plone Conference this year. Therefore, it might take us a little longer to answer support questions this week.

Many Portknox systems are powered by Plone like the website and the backend. Plone has an outstanding security track record and is therefore a perfect fit for Portknox.


Gegen Upload-Filter und Leistungsschutzrecht - Portknox unterstützt offenen Brief von Nextcloud an das Europäische Parlament

article13 uploadfilter

Ende März stimmt das EU-Parlament über ein neues EU-Urheberrecht ab. Problematisch: Mit Artikel 11 und 13 sind große Einschränkungen für User und Plattformen im Internet geplant.

Artikel 13 besagt, dass Betreiber von Internetplattformen künftig im Voraus jedes von Nutzern hochgeladene Bild, jede Tonaufnahme und jedes Video prüfen müssen und wenn eine Urheberrechtsverletzung vorliegt, nicht hochladen dürfen.


Arzikel 11 bezieht sich auf das Leistungsschutzrecht für Verlage. Im Moment gilt das Urheberrecht für ganze Artikel. Künftig sollen auch Linkvorschauen und Textausschnitte lizenzpflichtig sein.

Neues Feature "Portknox Cloud Backup" ab jetzt verfügbar

1 min read

Einige Kunden wünschten sich ein umfangreicheres Backup ihrer Daten und mehr Kontrolle über ihre Portknox Cloud. Da jede Cloud eine eigene Installation ist, kamen wir auf die Idee, die komplette Datenbank in den Dateien-Bereich des Kunden abzuspeichern.

Neue Kunden haben schon jetzt den Ordner "PortknoxBackup", bestehende Kunden müssen ihn nur anlegen. In diesem Ordner wird dann nächtlich das SQL Backup automatisch abgeleget.

Mehr Informationen findet ihr in der entsprechenden Anleitung.

How to add automatic nightly builds to your Nextcloud app

2 min read

For two years Portknox has been hosting the nightly builds for several Nextcloud apps. As we have to move to a newer server, I'll take the chance to document the nightly creation process. So, if you want to add nightly builds to your app here is a full automated and low-maintenance process. In case you need help or a place to save the builds just send us an email. We are happy to help!


- if [[ "$NIGHTLY" = "TRUE" ]]; then curl --ftp-create-dirs -T /home/travis/build/nextcloud/core/apps/contacts/build/artifacts/appstore/calendar.tar.gz -u $FTP_LOGIN:$FTP_PW$(date +%Y-%m-%d).tar.gz; fi

Cron Job on the nightly server:


# create structure
mkdir -p $ARCHIVE

# move directories in the current directory older than 14 days to archive
find $DATA -maxdepth 1 -type d -mtime +14 -exec mv {} $ARCHIVE \;

# delete data in archive
find $ARCHIVE -type d -mtime +90 -exec rm -rf {} \;

# Prepare curl request
body='{ "request": { "message": "Nightly build", "branch":"master", "config": { "env": { "matrix": ["DB=sqlite CORE_BRANCH=master TEST_JS=FALSE PHP_COVERAGE=FALSE PACKAGE=TRUE NIGHTLY=TRUE"] }, "php": ["7"], "matrix": { "fast_finish": false } } }}'
# Trigger nightly build curl -s -X POST \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -H "Travis-API-Version: 3" \ -H "Authorization: token <Insert token>" \ -d "$body" \

Portknox Update March

2 min read

Nextcloud 13 is here (in fact 13.0.1)

Early this month we finished migration of all Portknox clouds to Nextcloud 13 and with it nearly all apps have got an update. As you can see in our applist, Portknox now offers 41 supported apps.

Nextcloud Talk

One of the biggest enhancements is Nextcloud Talk which adds video & audio-conferencing to Nextcloud.

 Nextcloud Talk at

Please note that you will need a TURN server to communicate with users behind routers or firewalls. We offer an addon which is easy to setup.

End-to-end Encryption

Nextcloud 13 also adds a feature for client side encryption as a tech preview. We will test and follow the progress closely. Right now we don't ship this app to our customers, but it looks as if we will soon.

Whats next at Portknox?

Right now we are migrating clouds to our improved infrastructure. As every Portknox cloud is self-contained and isolated this needs to be done from time to time. We have done this in past, too.
