Systemd restarting A while ago I had a service that would need to be restarted after it had a cool down of about 2 hours… I had a stanza that stated Restart=always RestartSec=7200 which was cool because it would just autorestart when it died. At the time the restart would work just fine after the cooldown. The catch that I ran in to was because of that timer, if I logged in and tried to start it when it was in a failed state, the service would hang....

Synology time machine “How_to_back_up_files_from_Mac_to_Synology_NAS_with_Time_Machine. This will let you p[lug in a usb drive to a synolgoy nas and then from there configure an AFP share that mac’s time machine software will find and then allow network backups. It is still on site so it isn’t totally secure and reliable. But it is a pretty good use of a 2tb drive and a NAS. The initial backup is kind of brutal but then anything after that should be a bit better and faster....
Kerberoasting! Lets talk about some old security here. Kerberos! This is a couple years old but sadly still works. Kerberos is the authentication system for windows and ad networks.
