Topic: how to build a new Kernel

[Don]

I would like to try an E-Smith set up but I want to rebuild a kernel that includes some patches that are not part of standard Redhat / linux (the IPSEC patches discussed in the VPM howto to be preceise - it looks like FreeSwan does not meet my needs).   I'm quite comfortable with the mechanics of building a kernel on a normal linux distribution but I'm wondering what the .config file looks like for a standard E-Smith kernel.  If someone could help me get a copy of that, I would prefer to start from that point rather than taking my best guess as to what they use.

FreeSwan and the kernel IPSEC patches are the same thing.

Go to your nearest RedHat mirror and grab the src.rpm of the kernel, the config files are included in it.

[I do doubt that you really need to recompile a kernel, BTW. Kernel modules are a Good Thing.]

I there is a misunderstanding .... I am refering to the file that is created as a result of beginning the kernel build process via "make config" (or make menuconfig or ..... ).  You begin a long series of Q&A about what components you want, and if you want modules or built ins.  I just want to know what set of choices E-Smith starts with.

As far as the value of modules goes, yeah ... but you can't get everything you need that way.

As far as FreeSwan being equivalent to the application of the patches described in the VPM MASQUERADE HOWTO ... I don't think so.  Folks more knowedgable than I have said FreeSwan only supports B2B configurations that rely on static assignments of ip addresses on host and client.  I need support for a "session oriented" IPSEC connection.

Did you find the .config file for the kernel? I seem to have a similar problem and need the file.
Thanks

I believe the config file is located in the kernel-sources RPM.

Do you mean the .config file with e-smith kernel options is in RedHat kernel sources? Or rather that you get a .config file with the sources, a generic one with redhat generic options?
Most of e-smith kernel options are fine for most people, but not for everybody. It would be neice and simple to offer the original e-smith .config file in order to save time and trouble.
Thanks

It has been said many times before, but:
"The E-Smith 4.1.1 kernel is *exactly* the same as the RedHat-7.0 kernel"
This means that the .config in the RedHat src.rpm is the same as the .config used by E-Smith...

It is true that E-Smith then add aditonal kernel modules, but these are added by separate kernel modules, & so are not part of the main .config file...

Cheers,
Fran.

Fran, I have downloaded the RPMs according to the FAQ, installed (with some version problems, as e-smith has a more recent version than redhat of libstdc++), and configure the kernel. No way to get make menuconfig, apparently does not find curses.h.
When I make bzImage, it gives two errors (raid and cpu, peculiar). Then I consider is my fault, so I make bzImage with the original .config from the kernel source (the one you say is used by e-smith). The same errors.
Any hint?
