Ubuntu/Bespin/TIL
From charlesreid1
This page is the list of "today I learned" things that I learned while setting up a desktop Ubuntu 18.04 server.
Gnome
- Gnome is highly configurable, but the GUI gives zero control over those settings.
- Gnome themes are just files living in
/usr/share/themes - More themes available online
Networking
- Debian (Raspberry Pi, Kali) comes with dhcpcd baked in
- Ubuntu comes with dhclient baked in
- Difference between dhcpcd and dhclient? dhclient is older, provided by ISC, serves as a reference; dhcpcd is newer and more lightweight
- Network manager is a surprisingly difficult service to stop
- Ubuntu 18.04 server runs a stub dns server - resolv.conf, and the systemd-ressolved service - and it is extremely confusing because turning it off can disable the internet. So don't just go around deleting stuff!
- In 18.04, ubuntu changed the way network interfaces are named, so the mac address is hard-coded in the device name
