In PostgreSQL it’s quite easy to restrict access for user to some tables:
- create restrictive view
- grant usage on view schema
- grant select on view to restricted user
Really easy. And it’s not working when the restrictive view, is selecting from another view that is using function(s)!
I encountered this problem again, so let’s write it down to avoid googling it.
PowerDNS fails to start with
pdns.service: Failed at step ADDRESS_FAMILIES spawning /usr/sbin/pdns_server: Invalid argument
- edit /lib/systemd/system/pdns.service
- comment out RestrictAddressFamilies
- comment out ProtectSystem=full
- possibly kill systemd-resolved
- systemctl daemon-reload
- ask yourself again, why are you using debian with systemd on server ? And why the hell it is starting services I’ve never configured to start ? Isn’t it time to switch to windows ? It seems more predictable to me…
I’ve hacked together and up-to-date version of Asuswrt Merlin firmware for oldie but goldie Asus RT-N16 router. Beware, this firmware is only intended for use by advanced users.
tinc is a great mesh Virtual Private Network daemon, with just one little glitch (and also some little crypto problems ;-). I find its configuration really tedious and complicated compared to OpenVPN and its possibility to centrally assign IP addresses and push options to clients. I know, that’s the tax for being mesh, but wouldn’t it be great to configure your mesh network a bit centrally ?
Here is my solution for making Amlogic S812 based Beelink MXIII Plus Android TV Box work with Logitech Harmony universal remote. It’s based on solution described on this forum post, but modified to make it easier to use (if your Harmony remote is able to learn new IR commands).
