Would it be possible to do a release / module info for this repo as well? When helping users it would be good to know what version that is sitting at as well as everything else.

22

It has a tag: Release 1.0.4-beta · openenergymonitor/EmonScripts · GitHub

23

Yes but that isn’t visible in the admin page.

It just started to be an issue within the last month. Difficult to point to a day. Looks like the update script is running and updating things. With the last run on May 25.

Git: 
	URL :	 https://github.com/emoncms/emoncms.git
	Branch :	 * stable
	Describe :	 10.1.11-7-g90f39158

Yes. I use node-red on the remote Dakboard machine to read a motion sensor and turn off the Dakboard monitor when no one is in the room, and to format some of the solar and use data for display on the Dakboard.

At the moment I do. My emonCMS server is on the internet, handling traffic on port 80 and doing a reverse proxy to emonCMS and a few other internal servers. My home setup grew up around my emonCMS Pi, which is the reason this particular machine is the proxy server. I could divide that out to a separate Pi, but haven’t gotten around to it. So as things stand, the way I understand internet security, it is best to have ufw in place.

I will take a look at that. I tried disabling some of the things I knew to be requesting data from the emonCMS server, and the blocked requests kept rolling in. So there is something I put in place that I’m forgetting, or ufw is logging a blocked request even while my server is responding and things seem to be working otherwise.

25

My initial thought it is that (Port 1880).

Check you update logs, it should be on 10.2.3. It is only a manual update process for emoncms.

26

Update: The cause of apache2 going down was certbot. It was random because certbot tries to run at random intervals to distribute the timing of requests to their servers. The certbot service tries to use “apachectl -k start” to restart apache, and for some reason this doesn’t work, even though “systemctl start apache2” does work when I do so manually. Still investigating that here: Apache2 does not come back up, certbot finishes abnormally - #9 by brandock - Help - Let's Encrypt Community Support

In the meantime, /var/log is full again, and I could still use some help figuring out how to handle this situation. One strategy is to try to calm down the logging of Letsencrypt certbot and ufw, and I’m working on that, but shouldn’t the log rotating be able to handle the volume?

Regarding ufw and getting it to be less verbose. I took the suggestion to go to /etc/rsyslog.d/20-ufw.conf and remove the comment character before the &stop back when you suggested it. I have also added a specific “allow” rule for traffic coming from 192.168.1.80, my Dakboard node-red server that causes all the [BLOCK] entries in ufw.log. This hasn’t slowed down the logging a bit. I am suspicious that this is because the inbound hits from node-red all have different, seemingly random destination ports.

You need to look in the logs and work out what is causing the excessive logging - it is the only way to fix it. I suggest you cast your query wider to Stackoverflow [edit] (or the Node-RED forum) for instance as this is not an emoncms issue.

I have also suggested using tshark on the Node-Red machine and see if you can work out what is sending the requests. Maybe try stopping some flows and see if that stops the requests.

28

The issue is you have ignored the comment at the top that says do not edit this file.

The changes you made to ‘default-settings.ini’ need to be moved to the settings.ini file.

Then the files should be reverted to their GitHub state.

I cannot remember the correct command. Do…

cd /var/www/emoncms
git pull

and the message will tell you what to do to delete your changes.

[edit]
It is the same problem with the first git pull that fails but that is because of the logrotate fix you used. You can revert that change as I’m sure Trystan said the fix had been merged.

git checkout -- <filename>

will revert your changes so the git pull works.

29

I admit I did find it confusing as to which settings file I needed to edit. In the end I did put my changes in settings.ini, but maybe I left behind some differences in the other files. The change I made to settings.ini was max_node_id_limit = 64

Just now I did this.

pi@emonpi:/var/www/emoncms$ git checkout -- default-settings.php
pi@emonpi:/var/www/emoncms$ git checkout -- example.settings.ini
pi@emonpi:/var/www/emoncms$ git checkout -- example.settings.php
pi@emonpi:/var/www/emoncms$ git pull

Yep that worked.

Me again. /var/log is full again despite turning off ufw and certbot (I moved this setup to another machine). Any suggestions on what to do next?

For those that might benefit, here’s what I’ve learned in the last couple weeks.

  1. If you are going to run a reverse proxy on a Raspberry Pi within your network, don’t use the same Pi that you are using for emonCMS. Every time you need to restart apache2 to update your proxy settings, emonCMS is effected. And all the logging that you want from your proxy server is more logging than you might want on your emonCMS server. At least this is my opinion after what I’ve been doing lately.
  2. Cloudflare proxy makes a lot of sense, and Paul Reed has a nice write-up on how to set it up with ufw to limit traffic into your network to only that which has come through Cloudflare, including a script that keeps ufw up-to-date with Cloudflare’s current IP addresses.

So I now have a separate reverse proxy Pi inside my network that is looking for valid traffic from Cloudflare and proxying it to emonCMS.

I like this setup better, and I hoped it would resolve the full /var/log problem, but apparently not.

Those numbers do not seem to add up to 50M which is the size of /var/log
