BIRD doesn't compile
by David Rohleder 05 Apr '01

05 Apr '01

Hello, i have got a problem compiling BIRD 1.0.4 on newly installed debian box with gcc 2.95.3 gcc 2.95.2 compiles without errors (but with many warnings). Here is what i have got (seems that #include <time.h> is missing) on 2.95.3 io.c: At top level: io.c:438: warning: missing initializer io.c:438: warning: (near initialization for `sk_class.lookup') io.c: In function `io_init': io.c:1021: warning: implicit declaration of function `time' make[2]: *** [io.o] Error 1 make[2]: Leaving directory `/home/davro/source/bird-1.0.4/obj/lib' make[1]: *** [subdir] Error 2 make[1]: Leaving directory `/home/davro/source/bird-1.0.4/obj' make: *** [all] Error 2 when i added #include <time.h> to several sources, it has passed without errors. But i don't know if this is "the right way" to do it. -- ------------------------------------------------------------------------- David Rohleder davro(a)ics.muni.cz Institute of Computer Science, Masaryk University Brno, Czech Republic -------------------------------------------------------------------------

Is this an active project? There seems to be no changes since September 2000? Are all the developers on vacation? Permanently? -Ralph

About func in md5.c

Hi, All maybe i totally dont figure this right, in the func void byteReverse(unsigned char *buf, unsigned longs) { u32 t; do { t = (u32) ((unsigned) buf[3] << 8 | buf[2]) << 16 | ((unsigned) buf[1] << 8 | buf[0]); *(u32 *) buf = t; buf += 4; } while (--longs); } isnt that buf[3] should shift 24?

OSPF and strange area ID
by David Rohleder 07 Mar '01

07 Mar '01

Hello, i have got strange problem running OSPF: R ----- F ----- R is Bay Networks VNR F is Debian Linux 2.2 (with kernel 2.4.2) when i try to configure OSPF: protocol ospf MyOSPF { # rfc1583compat yes; area 0.0.0.2 { # stub no; # tick 1; interface "eth0" { cost 500; dead count 4; type broadcast; }; interface "eth1" { cost 550; dead count 4; type broadcast; }; interface "eth2" { stub yes; cost 10; }; interface "eth3" { stub yes; cost 10; }; }; } i am getting strange debug messages: Mar 7 16:32:53 fw5 bird: MyOSPF: Bad OSPF packet received: other area 33554432 Mar 7 16:32:53 fw5 bird: MyOSPF: Discarding and tcpdump shows: 16:29:36.338278 fw5.ics.muni.cz > OSPF-ALL.MCAST.net: OSPFv2-hello 44: rtrid 147.251.8.17 area 0.0.0.2 [|ospf] [tos 0xc0] [ttl 1] 16:29:43.932693 routics-are.brno.cesnet.cz > OSPF-ALL.MCAST.net: OSPFv2-hello 52: rtrid routics-are4.brno.cesnet.cz area 0.0.0.2 [|ospf] [tos 0xc0] [ttl 1] i don't see any neighbour. when i change area to 2.0.0.0 (33554432), bird doesn't drop packets and goes to state init/other with R, but tcpdump shows, that bird sends packets with area 2.0.0.0 which collides with R config. It seems to me, that bird does't do translation from net byte order to host byte order when receiving packets (I am not sure, but area 0.0.0.0 could work :-) -- ------------------------------------------------------------------------- David Rohleder davro(a)ics.muni.cz Institute of Computer Science, Masaryk University Brno, Czech Republic -------------------------------------------------------------------------

Re: Routing server traffic thru two external ips.
by Chuck Larson 07 Mar '01

07 Mar '01

Getting some good feed back, but I am getting the impression that bird may not be the solution. A few have mentioned loadsharing, and I have looked into this. The issue with loadsharing, from what I've read, my ISP must support that two NIC can share the same IP. The is not an option for me. What I do know is that I can add a route to a specific IP to the routing table and it transmits through the second NIC(eth1), default is eth0. There is no interuption to the game and works great. So if I have 12 hosts( with unique ips ), can bird modify the routing table to put 6 hosts on eth0, and 6 on eth1? Parameters to use could be port, protocol, (bandwidth?). My previous e-mail Hi, I am new and would like to know if this is possible with bird. I currently have a game server setup behind a linux router/firewall which is hooked up to two cable modems via two NICS( eth0 and eth1 ). The idea is that if I have 12( or more ) players, how do I tell the kernel( with me telling using route ) TX packets to 6 players on eth0 and the other 6 on eth1. Any thoughts?

question about func in Checksum.c
by Zheng Yuan {ZYUAN1} 06 Mar '01

06 Mar '01

Hi, all I have a question about the func static u16 ipsum_calc_block(u16 *x, unsigned len, u16 sum) I guess we dont need the first len >>= 1 i know we want to move 32 bits at one time, so second len >>= 1 can do it. The first one is redundant. static u16 ipsum_calc_block(u16 *x, unsigned len, u16 sum) { int rest; u32 tmp, *xx; ASSERT(!(len % 2)); if (!len) return sum; len >>= 1; if ((unsigned long) x & 2) /* Align to 32-bit boundary, use x's address */ { sum = add16(sum, *x++); len--; } rest = len & 1; len >>= 1; tmp = 0; xx = (u32 *) x; while (len) { tmp = add32(tmp, *xx++); len--; } sum = add16(sum, add16(tmp & 0xffff, tmp >> 16U)); if (rest) sum = add16(sum, *(u16 *) xx); return sum; }

config file
by David Rohleder 06 Mar '01

Hello, i have got another wish :-) when using ./configure, i would like to set location of bird.conf. ./configure --prefix=/ doesn't do that. It still asks for /usr/local/etc/bird.conf and changing default place for communication socket would be also nice. I know i can set it easily using options, but i prefer using standard locations when running without any option. -- ------------------------------------------------------------------------- David Rohleder davro(a)ics.muni.cz Institute of Computer Science, Masaryk University Brno, Czech Republic -------------------------------------------------------------------------
