I needed more serial ports that the basic CentOS Version 4 system is built to use so I'm using the following kernel build instructions to build the new 2.6 kernel: http://www.hylafax.org/content/Handbook:Basic_Server_Configuration:Modem-speci fic_Guidance I believe the procedure is correct but the kernel is not building. I used the "kernel-2.6.9-34.EL.src.rpm file that I found on one of the CentOS mirrors. Here are the problems that I've had so far. 1) The correct architecture to use. Does anyone know which architecture should be used for the Dell 2650 Dual Xeon processor? I thought the correct configuration file would have been "kernel-2.6.9-i686-smp.config". I've also tried "kernel-2.6.9-i586-smp.config" and run into the same problems. 2) When it built the rpm it was named "kernel-2.6.934.ELcustom-1.i386.rpm" but I would have expected it to be named "kernel-2.6.9-34.ELcustom-1.i386.rpm". Was it build using the correct name or might something be misconfigured. 3) When I entered the following command: "rpm -i /usr/src/redhat/RPMS/i386/kernel-2.6.934.ELcustom-1.i386.rpm" I get the following error: "error: Failed dependencies: kernel >= 2.6.10 conflicts with lksctp-tools-1.0.2-6.4E.1.i386" The "kernel >= 2.6.10" does not make sense but I was wondering if it had anything to do with the file being named kernel-2.6.934.... or is there some other problem I should be looking for? Ideas anyone?
