How to Modify/Change console/SSH login banner for Proxmox Virtual Environment (Proxmox VE / PVE)

The final banner text is stored in /etc/issue, but we should not change this file, instead we should change the script which produces the content for this file “/usr/bin/pvebanner“

1 To modify the /usr/bin/pvebanner file we can use the following command to back it up first then edit it

# Backup the file before editing

cp /usr/bin/pvebanner /usr/bin/pvebanner.backup

# Edit the file

nano /usr/bin/pvebanner

2 Modify then save the changes and exit the nano editor: Ctrl + X, Y, Enter key
