Subject: [UPDATE 1] I have confirmed that the latest Sophos Firewall SFOS version 20.0.0 GA-Build222 is using open source Snort as its Intrusion Prevention System (IPS) Good day from Singapore, I have started installing Sophos Firewall SFOS version 20.0.0 GA-Build222 on my Intel Celeron J3160 (4 GB DDR3L RAM + 64 GB SSD) on 16 Nov 2023 Thursday at 11.00 PM. Initially I had wanted to install Sophos Firewall on my newest Intel Celeron J4125 (8 GB DDR4 + 64 GB SSD) but the Linux Kernel version 4.14.302 wasn't able to detect Intel Ethernet Controller I225-V 2.5 GbE network interface cards. To workaround the problem, I had to install pfSense firewall version 2.7.0 on my Intel Celeron J4125 firewall appliance and then install Sophos Firewall on my Intel Celeron J3160 firewall appliance. Both pfSense and Sophos Firewall use open source Snort as its Intrusion Prevention System (IPS).

Subject: Teo En Ming has just discovered that the latest Sophos Firewall SFOS version 20.0.0 GA-Build222 is running on Linux kernel 4.14.302 Good day from Singapore, I have just discovered that the latest Sophos Firewall SFOS version 20.0.0 GA-Build222 is running on Linux kernel 4.14.302. # uname -a Linux localhost 4.14.302 #2 SMP Wed Nov 1 07:16:58 UTC 2023 x86_64 GNU/Linux However, I do not know which Linux distro Sophos Firewall is based on. When I run the Linux command "cat /etc/lsb-release", the output is DISTRIB_ID=Sophos Firewall Hence I do not know which Linux distro the Sophos Firewall is based on. Additionally, Sophos Firewall is also using the open source Snort Intrusion Prevention System (IPS) by Cisco. I saw the directory snort inside /etc/ when I am inside the terminal. I simply love Linux and open source! Billions of network security appliances and networking devices are based on Linux. Regards, Mr. Turritopsis Dohrnii Teo En Ming Targeted Individual in Singapo...

Subject: Bought portable air con for $604.59 on 30 Oct 2023 Monday  I have used $150 Fairprice vouchers to offset the payment. Hence I only pay $454.59 for the portable air con.  Portable air con was delivered on 1st Nov 2023 Wednesday at about 5.15 PM. Installation charges for the exhaust pipe at the push out window in my bedroom is $100. Paid using PayNow. The air con installation ended before 7 PM.  On the 1st night, the portable air con keeps turning off and on after midnight. The air con technician came to inspect on the 2nd day after 8 PM in the evening. Found nothing wrong except I had pressed the timer button a few times. On the 2nd night, the water tank in the portable air con was full after using it for only 6 hours. The portable air con was faulty.  The replacement portable air con was delivered on 3rd Nov 2023 Friday at about 3.30 PM. So far so good. The water tank in the replacement portable air con did not become full after 3 nights of operation.  ...
