Re: Kernel update for RHEL 5



I am not sure I would agree with either of the solutions presented in the thread. I understand that your systems need extra security. However, there is security in terms of availability and security in terms of confidentiality. To rely on a system to be available, just by upgrading the kernel is not a good idea. glibc, module-init-tools, and other dependences might introduce problems to the system if you just upgrade the kernel, especially if you do development work (compilers, dev libs?)
You need a proper way to handle the dependencies for these things.

If your employer wants the best solution about keeping RHEL systems up-to-date in a secure way, that should provide a proper RHN Satelite Server. It is essentially an advanced proxy server that stands between your system and the Internet and allows controlled upgrades. The procedure to obtain and setup this is given here:
https://www.redhat.com/rhn/

and at the bottom you should find various whitepaper links that give you an idea about what to expect when you implement this.

All:

	How can I update the kernel for my RHEL 5 systems?  I am not
permitted to connect them to the Internet, but may download files and
burn them to CD.  Since I will not be doing development work, should I
download all 14 or 15 files?

	Is this procedure documented somewhere?  Can anyone recommend a
book?
