Follow-up to my own post here: http://marc.theaimsgroup.com/?l=lartc&m=115332794424197&w=2 Problem ended up being that the tc included in the iproute RPM in Fedora Core 2 was built specifically against the headers in the glibc-kernheaders RPM. When I switched to a custom kernel (for built-in MPPE support), apparently some symbols referenced in the glibc-kernheaders package are not present in the non-RH kernel. This was causing my issue. Solution was to modify the .spec file for iproute and tell it to compile against my custom kernel's headers specifically. Specifically I had to make the following changes to the .spec file to get things to work: - Modify iproute2-2.4.7-kernel.patch to point to /usr/src/linux/include - Do not apply iproute2-2.4.7-misc.patch - Do not apply iproute2-2.4.7-in_port_t.patch This makes everything happy once again! I'm not sure what the consequenes are of not applying those RedHat patches, but the tool still works normally as far as I can tell.
