If I define more than 1 'kernel' protocol in the config I get a Segmentation fault when starting bird. The following are the definitions from the config: " protocol kernel kern1 { learn; # Learn all alien routes from the kernel persist; # Don't remove routes on bird shutdown scan time 20; # Scan kernel routing table every 20 seconds import all; # Default is import all export all; # Default is export none } protocol kernel kern2 { table dsl; kernel table 100; scan time 20; export all; } " The final lines from an strace are: " read(4, "", 8192) = 0 socket(PF_NETLINK, SOCK_RAW, 0) = 6 socket(PF_NETLINK, SOCK_RAW, 0) = 7 bind(7, {sa_family=AF_NETLINK, pid=0, groups=00000051}, 12) = 0 fcntl64(7, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ " But I haven't yet figured out exactly where in the code it is going wrong... any assistance would be greatly appreciated! My system is Debian 'Etch' running the 2.6.18-4-486 kernel. I can supply any further information as required. Thanks James
