Linux – How to load the dumthe network adapter in linux if it’s not as a module

ipseckernellinuxvpn

I want to build a roadwarrior ipsec gateway for routing traffic securely through my server.

For this, I plan to use racooon and debian linux. I have a VPS with a monolithic kernel (no kernel modules!), and since I need an internal NAT network for the VPn to work, I need some way to add a dummy interface to the kernel.

The question is, how can I see if dummy.ko is in the kernel built-in, and if it is, how can I activate it? modprobe dummy won't do. The VPS seems to be running under OpenVZ, and the kernel is from Redhat EL5. Is this impossible?

If there are other good solutions for accomplishing this roadwarrior setup, they'd be greatly appreciated.

Use ifconfig to bring it up.
