4 years ago So everything was graphing on my local network (192.168.5.0/24)in grafana... Unifi equipment, pfsense, etc... I then wanted to traceroute and i needed to install it with apt-get install, but that failed to contact server. Pinged google and some other sites, nothing. Turns out I didn't have a default gateway after I rebooted the VM!
$ sudo ip route add default via 192.168.5.1 $ traceroute 192.168.100.1 traceroute to 192.168.100.1 (192.168.100.1), 64 hops max 1 192.168.5.1 0.522ms 0.509ms 0.528ms 2 192.168.100.1 1.296ms 0.715ms 0.940ms $ service py_arris_exporter start
Closed. The confusing error message output did not lead me down that path.
I got this to work fine for a few weeks but after a reboot the application will no longer start on Ubuntu LTS 20.04
