Did some investigating, and this patch fixes the problem for me: " diff -ur bird-1.0.11.old/sysdep/unix/krt.c bird-1.0.11/sysdep/unix/krt.c --- bird-1.0.11.old/sysdep/unix/krt.c 2004-06-08 02:51:23.000000000 +1000 +++ bird-1.0.11/sysdep/unix/krt.c 2007-08-14 20:41:20.000000000 +1000 @@ -769,9 +769,9 @@ #ifdef CONFIG_ALL_TABLES_AT_ONCE if (first) krt_scan_timer = krt_start_timer(p); - else - tm_start(p->scan_timer, 0); p->scan_timer = krt_scan_timer; + if (first) + tm_start(p->scan_timer, 0); #else p->scan_timer = krt_start_timer(p); #endif " tm_start(p->scan_timer, 0) was being called before p->scan_timer was set when the second kernel protocol was set up. I'm not entirely sure if the 'if (first)' I added is even required, or if the krt_start_timer(p) is sufficient... James

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
