Public bug reported: Hello,
I am running Armbian Xenial 5.60 on a Rock64 single board computer, which is based on Ubuntu 16.04. I have noticed that monit (xenial,now 1:5.16-2 arm64) does not detect when a port is closed on this particular setup. For example, I have the below entry in my "monitrc" config file; check host MYHOST with address 192.168.1.12 if failed port 4444 then alert And although port 4444 is actually closed , monit does not view it closed... here's an extract of the debug log when starting monit as "monit -Iv" Socket test failed for [192.168.1.12]:4444 -- Connection refused 'TEST' succeeded testing protocol [DEFAULT] at [192.168.1.12]:4444 [TCP/IP] [response time 0.701 ms] 'TEST' connection succeeded to [192.168.1.12]:4444 [TCP/IP] If I use a non existent IP to test, it seems to work and fail at the ping test, yet it cannot tell if a port is closed and always marks it as open. * OS release: Description: Ubuntu 16.04.5 LTS Release: 16.04 * monit version $ sudo apt show monit Package: monit Version: 1:5.16-2ubuntu0.2 Priority: extra Section: universe/admin Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-disc...@lists.ubuntu.com> Original-Maintainer: Sergey B Kirpichev <skirpic...@gmail.com> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 777 kB Depends: libc6 (>= 2.17), libpam0g (>= 0.99.7.1), libssl1.0.0 (>= 1.0.2~beta3), lsb-base (>= 3.2-13) Please let me know if more info is needed. P.S. I have another monit (5.20.0) running on a Raspian 9.6 which detects failed ports with no issues, so I believe this should work in monit 5.16 as well.
