Describe your issue

Hi,

I think my issue is similar to Can not start fail2ban , fail2ban doesn’t start and the logs point to a missing jail for a specific app (in my case streams__2). I tried using the command given and replacing the name of the app but that didn’t work.

The logs are below but in short fail2ban fails to start because:

What does sudo ls -l /var/log/streams__2 return ?

Also can you elaborate if you did anything specific before this started happening ? Did you just install streams__2 ? Or did you upgrade it ? Or anything else ?

3

Hi, thanks for answering.

The command returns: "ls: cannot access ‘/var/log/streams__2’: No such file or directory

I restored the streams that I had backed-up from the raspberry pi setup on the new hardware. No new upgrades or anything. I should add that I am able to connect to streams__2, so the app itself works. (it is __2 because I had first tested streams on another domain)

4

I just checked, and although I can access the app and it is online, it is not listed with the services in the admin webportal?

5

Hmpf yeah sounds like the restore script of the app is inconsistent …

Anyway you can recreate the log dir with sudo mkdir /var/log/streams__2 and chown streams__2 /var/log/streams__2, but it’s puzzling that the app did work without the log dir existing …

6

Hi, the commands came through, but fail2ban still doesn’t want to start (same error messages)? Any other ideas?

7

zblerf yeah it probably also wants the log file to exist so let’s run

sudo touch /var/log/streams__2/php.log
sudo chown streams__2 /var/log/streams__2/php.log
8

Hi, I tested it, and even fresh installs of streams don’t seem to be listed in “services” although with fresh installs that issue is ignored by fail2ban for some reason. I gave up, but thanks for your help!!
