ProxMox Notes
Post-Install Tasks
Disable/remove the annoying "no subscription" message that pops during login
Visit https://free-pmx.pages.dev/tools/free-pmx-no-subscription/ and install the package located there.
Set up notification emails
Datacenter > Notifications
Set up remote syslogging
apt update && apt -y install rsyslog
Once installed, edit /etc/rsyslog.conf and add the following section to the bottom; provide the proper IP address where noted:
# Remote syslog config *.info;daemon.notice;authpriv.* @<log aggregator IP>:514
Install lshw
apt update && apt -y install lshw
Suppress repeated smartd alerts
Edit /etc/smartd.conf and add entries such as the following:
/dev/sda -C 197+ -C 198+
This will cause smartd to send emails only if the selected parameters increment; otherwise emails get sent every 24 hours as long as the values remain non-zero (which they always will once they aren't).
Useful Notes and Tips
CLI command qm is your friend. List/manipulate VMs and such with this utility.
Enable remote VNC login ability to ProxMox guests
Edit the file - /etc/pve/local/qemu-server/<VMID>.conf
Add args: -vnc 0.0.0.0:77 to the end of the file (choose a unique number after the : for each guest)
A VNC connection to the guest is now possible by specifying the host IP address and the port chosen (“5977” in the example above).
