secumod+problem+2.4.18

Hi all I installed secumod (compiled for 2.4.10-4GB). Im using kernel 2.4.18 (installed and compiled by me). When I do a insmod -f secumod.o (because I get a warning about kernel version mismatch 2.4.10-4GB!=2.4.18) profs=1 the module is inserted but nothing happens. Users are still able to see each other procs. I tryed to compile secumod for 2.4.18 but I get alot of warnings and errors about the includes. Any ideas? Thank you very much Best Regards, João Seabra
