Are you sure CentOS comes with a kernel > 3.13?
As I'm reading the release notes on RHEL it says RHEL 7.2 2015-11-19 3.10.0-327.
I am trying to follow this SYNPROXY tutorial at http://www.seflow.net/2/index.php/en/blog/synproxy-module-protect-yourself-by-syn-flood by @matteob
It says:
Is that mean any kernal version for CentOS 7 but 3.13 for other distributions?
Sorry for my little knowlege of linux.
As @msg7086 says...however, you could verify yourself by doing a "yum update" (without answering Yes) and seeing what updates to the kernel package are offered. If there's a 3.11 kernel, you can just yum update it and reboot.
I'm assuming you're on KVM here...OpenVZ is a different story.
Yea, note the word or.
There tutorials available on google about upgrading linux kernel to stable 3.18.4 etc but i am not sure if it's gonna work fine?
You can use elrepo http://elrepo.org/tiki/tiki-index.php
Edit: see http://elrepo.org/tiki/kernel-ml
i already did yum update and after that it says kernal 3.10. I am currently testing the setup on my KVM VPS but once confirmed i will make it online on my OpenVZ VPS that i use for my sites.
Will test it out and see if it works on 3.10
Just checked they have 4.6 as the current stable version not sure if it's gonna work fine with cent o?
Besides, CentOS / RHEL will only use one kernel base-version per major release. That being said, CentOS 7.3, 7.5, 7.8, etc, all future 7.x will also be on 3.10.0 and you'll never see 3.11+ on this major release. It's by design.
You not need to upgrade it. If you have CentOS 7 the developers backported this module to work in el kernel. Just follow the howto loadings right kernel modules. CentOS 7 is synproxy ready
yup
or get a linode kvm vps they all default to kernel 4.5.5+
Thanks for explaining
oh ok so i can just go ahead with the tutorial because CentOS is already installed and updated.
yes
