How to update bind and postfix in Centos 5.8?


Well the current version of bind is BIND 9.3.6-P1-RedHat-9.3.6-20.P1.el5_8.1 in our name server whereas the latest has reached to 9.9 and even the version of postfix used in the system is 2.3 whereas the latest is 2.9...

SO how do i update then as thsi does not happen automatically like other packages...

And does anyone knw what version of bind and postfix does centos 6 support or does it provide when we do fresh install?

why do you want to? If you have no reason to do so, then don't. Keep the packages upto date from the CentOS repostorires and you will have a secure patched system, as opposed to a less secure version of the software which has features you won't be aware of. Don't update for the sake of it.

As for the other versions on EL6, just google "postfix EL6 rpm" or look in the centos repos that you're already using.

because the latest package is the stable one and has more security features that's why..

Ahh, well that's where you're wrong. All stability security issues are backdated by redhat into the releases, new buggy features are not. You will be more secure sticking with the CentOS / RedHat official versions.

oh ok...

But then why is it so that the Centos 6.2 has bind 6.2 in the fresh install of bind itself?

I presume you meant bind 9.whatever, not bind 6.2?

Because each major release of RHEL will potentially use different version. Many people will stay away from a .0 and even a .1 release of an enterprise distro to allow a period of back porting to occur before upgrading to the newer versions. You certanily don't want to stay on the old code base forever, but there is a strong need to ensure that whatever ran on rhel 5.0 a few years ago will also run on rhel 5.8 etc. Not so for the next major version which has the right to add and remove features in the name of progress.
