How do you get the kernel config to compile a new kernel?

Question

I have patched several kernels in the past with GRsec but have always been able to find the config under /boot. This is a OVH box but I can't find any config located anywhere.

Is there a way to get the config or how do I compile a kernel blind without a prebuilt config?

You can download the .config file from here

wget ftp://ftp.ovh.net/made-in-ovh/bzImage/3.14.32/config-3.14.32-xxxx-grs-ipv6-64

I found out that you can do the following:

cp /proc/config.gz ~
gunzip config.gz
cp config ~/linux*/.config

Or more simply `zcat /proc/config.gz >.config`. The file `/proc/config.gz` doesn't exist everywhere, it requires a patch to the mainstream kernel. – Gilles 'SO- stop being evil' Dec 19 '16 at 00:57
