I saw this article regarding limitations of Home Assistant external access. I think there are at least two things you can do:
- (If Apache is front-ending HA) Use mod_security / SSHguard to catch common attacks
- Require mTLS for external client access
Update Arch packages requiring rebuild
Eg after python upgrade, choose “clean rebuild” after.
yay -S $(checkrebuild -v | grep foreign | sed -e 's/^foreign//')
Custom Chrome useragent with Python Selenium
transitioning from screen to tmux
GNU screen is deprecated in redhat 7 & unavailable in redhat 8
The usurper tmux is available however, and with a compatibility config (I prefer to set the bind-prefix to ^W) things can be made bearable.
This shell function will help with the muscle memory of screen -r
screen () {
if [[ "$1" == "-r" ]]; then
tmux attach-session
else
tmux $@
fi
}Writing Python unit tests for HTTP Clients
I have a nagios / icinga HTTP monitor based on PyCurl: check_pycurl3.
Writing tests for this is difficult because:
- It needs to make HTTP requests and get a consistent response (so can’t rely on random internet websites).
- You cannot mock the HTTP requests as the modules for doing this rely on using more “standard” Python HTTP packages (like urllib or requests).
- Just spawning Flask or similar won’t work as it goes into its request loop and won’t process any tests.
So with a little StackExchange googling, you can start Flask in a thread (remember to set daemon=True) like below:
flask = threading.Thread(target=lambda: self.app.run(host=self.host,
port=self.port, debug=False, use_reloader=False),
daemon=True)
flask.start()You also need to give it some time to start up before tests commence, I’ve used the hacky approach of a 1 second sleep.
To see how I set up routes & inhibit flask startup messages, check the code!

dnf upgrade crashing on free oracle cloud vms running OEL8
There are 2 reasons for this: the memory on these VMs is small (668MB) & DNF is badly written and uses 100s of MBs. Secondly Oracle Linux includes a lot of repos.
1. install microdnf by wgetting it (as dnf is failing)
wget https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/x86_64/getPackage/libpeas-1.22.0-6.el8.x86_64.rpm
wget https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/x86_64/getPackage/microdnf-3.4.0-4.el8.x86_64.rpm
rpm -ivh *.rpm
2. Upgrade base repos
microdnf update –disablerepo=* –enablerepo=ol8_baseos_latest –enablerepo=ol8_appstream
Whoops
