Patch-linux-m1 is a software that adds a layer of security to Linux systems by randomizing IP id numbers, preventing portscans based on IP id. This kernel patch is designed to enhance the security of the Linux operating system.
If you're looking for a way to increase your security when using Linux, you might want to check out patch-linux-m1. This is a kernel patch that randomizes IP id numbers, making it much harder for anyone to conduct IP id portscans. While it's not completely fool-proof, it does randomize 8 bits out of a total of 16 bits, which means that it's much less likely that IP ids will be reused too soon.
What does this mean for you? Essentially, it means that someone would need to send 256 packets (or 255, if the port was open) for every port they wanted to scan. Given that packets can get lost on the internet, this makes it even more difficult for anyone to perform a successful attack.
One of the nice things about patch-linux-m1 is that it can be turned off both at compile and runtime through the /proc/sys/net/ipv4/ip_random_id file. Additionally, this patch is designed to work on all architectures, so you don't need to worry about compatibility issues.
However, it's important to note that patch-linux-m1 isn't necessary for 2.4.x kernels. This is because these kernels have a better system for IP id randomness built in.
If you're wondering how stable patch-linux-m1 is, you'll be pleased to know that it's been tested extensively. For example, it was run on ftp.habets.pp.se for a full 180 days without any issues (until a UPS failure caused downtime). In other words, you can feel confident that this patch is stable and reliable.
Overall, if you're looking for a simple way to improve your Linux security, patch-linux-m1 is definitely worth considering. Just keep in mind that while it's not fool-proof, it does make it much harder for anyone to attack your system through IP id portscans.
