Definitely will. Only problem is I still need vmware and cisco vpn,
and these two modules cannot compile on 2.6.24-rc1. Does anyone have a
patch for these? Last time I posted some patches for these, I got yell
at. But I need to work at the same time.

These are good tools for me to work with.

Thank you,
