Technical Tip: How to backup the FortiGate configuration file using Linux Mint as TFTP server

[bkarl]

Description	This article describes how to back up FortiOS & YAML format configuration files using TFTP service as a TFTP server on Linux Mint 21.1 Vera.
Scope	FortiGate version 7.2.3 or earlier.
Solution	On Linux Mint, open a terminal tab and enter the following command: sudo apt update Install TFTP service: sudo apt install tftpd-hpa Verify that the TFTP services are already running: sudo systemctl status tftpd-hpa Once the last step is done, it will be possible to configure the TFTP file of the service. Access the file and edit it: sudo nano /etc/default/tftpd-hpa Change the TFTP directory path and TFTP options only: Before: TFTP_DIRECTORY=”/var/lib/tftpboot” TFTP_OPTIONS=”—secure” After: It will then be possible to save the changes made before by pressing Ctrl + O, then S, then Ctrl + X (to exit). It is now necessary to create a new folder in order to match the path configured before. sudo mkdir /tftp sudo chown tftp:tftp /tftp   <----- This command changes the ownership of the folder. Restart the service and check that it is running properly. sudo systemctl restart tftpd-hpa sudo systemctl status tftpd-hpa Now go to FortiGate-VM 64 (in this case FortiOS 7.2.3 build 1262 is used). As an example: execute backup yaml-config tftp backup_test_yaml.conf 10.124.100.12 execute backup config tftp backup_test_FortiOS.conf 10.124.100.12 YAML: FortiOS: Notes: Consider that the TFTP Server should be reachable by FortiGate.
