The "iptables" functionality is installed with the Operating System; any updates would usually only come from the Linux distribution that is used, such as RHEL or CentOS.
If not referring to an OS software update, are you referring to just the rule set or configuration of iptables?
Thank you Don for replying.
What I intend to do is to upgrade IPTABLES to the latest version, I am using REDHAT Enterprise 5.2 i686 standard.
It seems there is a bug in older IPTABLES:
Updated iptables packages that fix a bug are now available.
The iptables utility controls the network packet filtering code in the
These updated packages fix the following bug:
* the memory alignment of ipt_connlimit_data was incorrect on x86-based
systems. This update adds an explicit aligned attribute to the
ipt_connlimit_data struct to correct this. (BZ#529687)
Users are advised to upgrade to these updated iptables packages, which
resolve this issue.
That is why I want to update my server to the latest IPTABLE version.
Can you tell me how to do it?
(By the way HAPPY NEW YEAR!!)
