A question about kernel options


Dear all,

I have been told that in order to support equal cost multipath for my linux box, I have to enable some options in kernel and re-build the kernel. Here is the problem, I would like to check my existing kernel configuration to see if those options are enable. If so, I will not need to re-build my kernel.

Can anyone tell me the ways to check those options?

Here are options that I need to enable

CONFIG_NET_SECURITY
CONFIG_FILTER
CONFIG_IP_ADVANCED_ROUTER
CONFIG_NETLINK
CONFIG_IP_MULTIPLE_TABLES
CONFIG_IP_ROUTE_MULTIPATH
CONFIG_IP_FIREWALL
CONFIG_IP_FIREWALL_NETLINK
CONFIG_NETLINK_DEV
CONFIG_IP_MASQUERADE

Thank you in advanced.

Best regards,
Jeff Li

What distribution of Linux do you have? Although I don't agree with the availability, Mandrake and RedHat have a Linux Kernel Config option in the Preferences/System menu. You could go through it like that, or go to prompt and to your /usr/src/linux directory and type make menuconfig and go through the options that way. The default options are set by the /usr/src/linux/arch/i386/defconfig file in which you can run through in any editor and see if you haven't recompiled since. The last is probably the easiest.

I think that most distros ship with a kernel with CONFIG_IP_ADVANCED_ROUTER disabled.
