Thank you for taking the time to report this bug and helping to make Ubuntu better.
I used "nc -l 4007" to examine what the plugin was actually sending, and I can confirm that the Host: header doesn't appear when testing check_http on 20.04. However, I'm not sure this is really a bug. check_http (on 20.04 at least) has both -I and -H options. If I use "-I 127.0.0.1 -H www.example.com" then the Host: header is set correctly. I haven't looked to see what the specified behaviour should be in the case that -k is used for headers that you'd expect the plugin to set itself directly. Is there anything to say that this should work at all? If you use "-I 127.0.0.1 -H www.example.com", then does that work for you? If not, please could you explain your use case? ** Changed in: monitoring-plugins (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940525 Title: check_http regression, 2.2 ignores -k Host header To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/monitoring-plugins/+bug/1940525/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
