Subject: I can confirm that Fortigate firewalls are definitely based on Linux


Good day from Singapore,


These few days, I have discovered that the output of the Fortigate firewall CLI command "diag hardware sysinfo cpu" is exactly the same as the output of the command "cat /proc/cpuinfo" in Linux operating systems. Hence I can confirm that the underlying operating system of Fortigate firewalls is definitely Linux. But I do not know which Linux distro Fortigate firewalls are based on.


Fortigate 90E firewall has 2-Core Intel(R) Atom(TM) CPU  C2338  @ 1.74GHz processor.


Fortigate 101F firewall has 8-core ARMv8 Processor rev 4 (v8l) 1400 MHz processor.


Fortigate 200F firewall has 8-core Intel(R) Xeon(R) CPU D-1627 @ 2.90GHz processor.


I will try to find out what processors my own personal Fortigate 60D and Fortigate 60E firewalls have later on.


I have configured and deployed 22 Fortigate firewalls for 20 companies/organizations in Singapore so far (as of 22 June 2023 Thursday). On 15 June 2020, I joined my present company (Systems Integrator/Managed Services) as an IT support engineer. I have been working at my present company for slightly more than 3 years already. My 3rd anniversary falls on 15 June 2023.


The following are useful commands for troubleshooting high CPU usage on Fortigate firewalls (provided by Fortinet technical support).


get system status

get system performance status --run 5 times

diag hardware sysinfo cpu

diag sys top

diag debug crashlog read

execute tac report


Do you guys know which Linux distro Fortigate firewalls are based on? I would like to know. This will be very interesting.

How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023)

Subject: How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023) It is a Well-Known Fact that government(s) invented mental illness to punish and torture people (and their families) who criticise the government or say bad things about the government. The Singapore Government rewarded my mother with a mental illness (schizophrenia). By leveraging mind control technology, the Singapore Government is able to make my mother hear voices in her head and trick her into believing that her neighbors are scolding her and targeting her everyday. Yes, the Singapore Government resorted to using this trickery. My mother firmly believes that her neighbors are scolding her and targeting her everyday. So we sold off our 1st HDB flat at Bedok North Street 3 and purchased another HDB flat at Yishun without careful consideration, planning and advice. When we moved to the HDB flat at Yishun, my mother still firmly believes that her neighbors are scolding her and targeting her every...
