Summary of the issue you are facing:
Im running nextcloud as test on snap.
Today nextcloud suddenly started to communicate with a github IP at full 100Mbit WAN connection speed.
Is this normal?
My disk was full so i gave it some more space and then it stopped.
I have now turned off the server just to be on the safe side.
But is it normal for it to suddenly connect to github and either send or recive at full speed?
Hey @offerlam, welcome to the Nextcloud community and thanks for supporting Nextcloud snap
Sorry to hear you are having issues with your Nextcloud snap installation. If you’ve come this far, you’re on the right track! There is a good chance someone in the community has had a similar issue and knows how to resolve it. That depends on how you request assistance. So read your request for tone, avoiding hyperbole and assuming good intentions.
In order to help you we’ll need some Information to get an Idea of your setup, so complete the required support template if you haven’t done so already or run the debugging script and post the result here.
Below are some links to how-to’s answering frequently asked questions and may help you help yourself;
Without your logs we’d be guessing. But run the debugging script and post your log here so we can take a look.
My snap has been running 24/7 since 2019 and I’ve never experienced what you’re describing. Also in all my years documenting and supporting the snap, nothing similar has ever been mentioned.
come to think of it, we released Nextcloud 32.0.5snap1 recently. The snap may have tried to auto update on your system (How to manage automatic updates in Nextcloud snap) and run into that zero-space issue you mentioned. thus the snap could not auto update correctly due to space issues and fall back to the last revision as expected… so yes “normal” if you like.
but as mentioned above, we’re guessing and that’s helping no one right?
So snap nextcloud does get its updates from github?
I’m trying to determin if i have been hacked or not.
Sadly i have been busy the last 5 days and now the log files are to new. The log data is gone.
Can you perhaps give me your risk assesment if it was proberly the update you are talking about? I mean i don’t think hackers would use thire access to a nextcloud server to access github at full speed or am i wrong?
I doubt it… and there is no reason to call GitHub unless you have the GitHub integration app installed! also Nextcloud upstream has a “feature” called firstrunwizard which obviously tries to retrieve some files from Nextcloud server GitHub. There have been upstream issues mentioning that the connection sometimes fails.
