Hi!! I'm trying to use cuseeme patch with netfilter and downloaded the patch from the cvs repository. While building the kernel with the new patch, i'm not able to do linking. The reason is the cuseeme(ip_nat_cuseeme.c) is using function ip_nat_mangle_udp_packet() function which is not defined. Please let me know, if i'm missing some other things while adding the patch. Thanks in advance. regards -prasanth Error dump while building the kernel: net/network.o: In function `cuseeme_mangle_outgoing': net/network.o(.text+0x4c498): undefined reference to`ip_nat_mangle_udp_packet' net/network.o(.text+0x4c498): relocation truncated to fit: R_ARM_PC24 ip_nat_mangle_udp_packet net/network.o: In function `cuseeme_mangle_incoming': net/network.o(.text+0x4c514): undefined reference to `ip_nat_mangle_udp_packet' net/network.o(.text+0x4c514): relocation truncated to fit: R_ARM_PC24 ip_nat_mangle_udp_packet net/network.o(.text+0x4c56c): undefined reference to `ip_nat_mangle_udp_packet' net/network.o(.text+0x4c56c): relocation truncated to fit: R_ARM_PC24 ip_nat_mangle_udp_packet net/network.o(.text+0x4c5f4): undefined reference to `ip_nat_mangle_udp_packet' net/network.o(.text+0x4c5f4): relocation truncated to fit: R_ARM_PC24 ip_nat_mangle_udp_packet make[2]: *** [vmlinux] Error 1 make[2]: Leaving directory `/home/krishnap/work/lsi/homebase/linux/linux-2.4.10' make[1]: *** [obelix] Error 2 make[1]: Leaving directory `/home/krishnap/work/lsi/homebase/linux'
