November 4, 20223 yr Hello. I have a few dockers with static IPs set via br0 They work great for unspecified amount of time, 10 until the last occurence, then become unreachable. my setup 192.168.0.1 - gateway 192.168.0.2 - server 192.168.0.10 - dock1 192.168.0.11 - dock2 i have console access to dock1 from unraid web interface i CAN NOT ping dock1 from server . dest host unreachable i CAN NOT ping server from dock1. dest host unreachable i CAN ping gateway or dock2 from dock1 looks like by bridge gets broken but i can not find a way to prevent it or restore without reboot. Any advice appreciated. How to catch a bug? What log can contain useful data? How to repair bridge wo reboot?
November 4, 20223 yr I'm guessing that on Settings -> Docker, you have "Host access to custom networks" enabled? Go to Tools -> Diagnostics and download your diagnostics. Then go to Settings -> Docker and disable Docker, Apply then enable Docker, Apply. Hopefully that solves it? If so, grab a second set of diagnostics and upload both here. I am trying to track down what changes when disabling/enabling Docker that resolves this.

November 4, 20223 yr Glad to hear you can recover without having to do a full reboot! I'm working on other projects at the moment, would appreciate if someone can help identify differences between these two diagnostics that would explain how enabling/disabling Docker resolves this

Can you please give me the output from: grep -R "" /proc/sys/net/ipv4/* when it is working and when it's not working next time before you fix it (preferably in text files named something like "bad" & "good")?

It looks like you never had a chance to check it out but it still happens every few days. I am going to make a cron script to ping docker in question and make /etc/rc.d/rc.docker restart but it does not look like a permanent solution update: bad https://pastebin.com/82BgJ7kS fixed https://pastebin.com/nxBA8zYZ

Sorry forgot to reply, real life came in the way… I see nothing obvious from the output… What do you mean that it happens every few days? Do you reboot the server that often or do you loose host access randomly? May I ask for what you need host access?

Do you reboot the server that often or do you loose host access randomly? May I ask for what you need host access? NVM I totally get it. just had a hope it would be something obviuos. My topic was badly formulated. Let me explain. 1. I have a router that routes selected IPs from lan to vpn tunnel 2. To make some of unraid containers work with this setup i gave them fixed ips with bridge network. 3. I do not monitor those dockers 24\7 but once in a week i do and sometimes they are not available 4. Rest of a system work perfectly fine. 5. Remote access to this server was configured through another container so I had to reboot because there is no "restart" option in docker settings menu and "stop" would kill my remote access as well Now I have a wireguard confiured so when it happens again I can restart docker service without reboot. My setup is not a best one ofc but it had months of uptime. Edited December 11, 20223 yr by winterx
