Why userspace rather than writing kernel space modules?
by Daniel Holmlund 11 Jun '01

11 Jun '01

Hi everyone, I'm a newbie to BIRD who ran across it from freshmeat.net. Being a newbie, I have some newbie questions. How efficient is it to sync with kernel space routing tables if the routing tables change rapidly? How often does a routing table change with a typical server configuration and typical server traffic? Lastly besides the portability, why implement a userspace daemon that is required to sync with the kernel when kernel space modules could be written to directly manipulate the routing tables themselves? Thanks for answering these questions. Currently, I am EXTREMELY interested in this project, and would like to potentially put some development time into BIRD. Daniel Holmlund --

Hello! Yes, BIRD is changing again! I just released 1.0.5 version. It's just "stablization release". No new features, just bug fixes. For 1.0.6 I prepare multiple OSPF areas. Kind regards Ondrej Filip

multiple kernel tables synchronization
by Luben Karavelov 07 May '01

07 May '01

I have found that trying to synchronize multiple birdc routing tables with multiple kernel routing tables through 2 instanes of "kernel" potocol crashes the bird daemon. I am using linux-2.4.4, libc6 v2.2.2. It crashes in rm_start in io.c:185, which is called by krt_start in krt.c:766 I found that this is the case when CONFIG_ALL_TABLES_AT_ONCE is defined, so I have commented out this definitions in /sysdep/cf/linux-2.2.h and /sysdep/cf/linux-v6.h and and now bird runs happily. I have no knowledge how to fix the problem with CONFIG_ALL_TABLES_AT_ONCE case, so its just a bugreport Luben -- _________________________________________________________ Luben Karavelov [phone] +359 2 9877088 Network Administrator [PGP] http://www.bgone.net/pgp/luben.asc [ICQ#] 34741625 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

RIP quiet mode?
by Raymond E. Marcil 02 May '01

02 May '01

Hi All, I'm using Bird v1.0.4 and trying to setup RIP to accept RIP routes but not broadcast any routes on a specific interface, in the following example eth0. I realize I could configure an export filter to block broadcasting all RIP routes but I'd like the capability to block broadcasting based on specific interfaces. The problem is that in "quiet" mode bird doesn't seem to accept routes, when I check the list of routes with route -n. Other modes like broadcast and nolisten work fine. Following is a copy of my bird.conf file. Thanks! Ray ray(a)spectrumwireless.net log syslog all; protocol direct { interface "-lo*", "*"; } protocol kernel { learn yes; persist yes; scan time 20; import all; export all; } protocol device { scan time 10; } protocol ospf { disabled yes; } protocol rip { interface "eth0" { mode quiet; }; import filter { if net = 0.0.0.0/0 then { reject; } else { accept; } } export filter { if net = 0.0.0.0/0 then { reject; } else { accept; } } } protocol static { }

init scripts

hello, becasue I have found in th archive that there is a discusion about the startup scrip of bird, i would like to suggest something like: start-stop-daemon --start --background --exec \ /usr/sbin/bird -- -d -D /var/log/bird that i have made on my debian system. it was hard to find where the "print" messages end when running bird with the default scrip. it's only a suggestion luben -- _________________________________________________________ Luben Karavelov [phone] +359 2 9877088 Network Administrator [PGP] http://www.bgone.net/pgp/luben.asc [ICQ#] 34741625 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

RIP na vice interfaces
by Martin Edlman 25 Apr '01

25 Apr '01

Zdravim, nazaril jsem na nasl. problem. Mam BIRDa na routeru, kde jsou tri interface, eth0 (WaveLAN), eth1, eth2 (3c509). Potrebuju, aby mi RIP chodil na vsech interface, ale nechodi. Prijima data jen z eth0, vysila na vsechny. Ja ale potrebuju prijimat na vsech a to multicastem. bird tvrdi, ze posloucha na vsech interface >>> ripOUT: Listening on eth2, port 520, mode multicast (224.0.0.9) >>> ripOUT: Listening on eth1, port 520, mode multicast (224.0.0.9) >>> ripOUT: Listening on eth0, port 520, mode multicast (224.0.0.9) Kdyz sleduju tcpdumpem data, tak mi z eth2 prichazej multicastovy rip2 pakety, ale v birdu se neobjevi, mam v protokolu ripOUT zapnuto "debug all". Co s tim? Lze nejak dosahnou toho, aby se paket/data/route/... objevil v birdu? Mam to na LinuxRouteru 2.9.8 s kernelem 2.2.19. Edas

failover nat
by Me Blah 22 Apr '01

22 Apr '01

hi, we are trying to set up a failover nat. we have a machine with 3 nics - one for local net, eth1 for T1 and eth2 for dsl. what we are trying to acomplish, is when T1 link goes down, the kernel routing table gets updated so that dsl becomes the default gw, and once dsl goes under, T1 takes its place (it its up). ip masquerading and local network are set up and functioning, but the failover mechanism isnt working. another thing i would like to clarify, is: do i have to make any changes to the routing table myself, such as adding default routes by hand, or should bird take care of that completely by it self? we use linux redhat 6.2 on x86 machine, kernel 2.2.19 and the latest version of zebra. thanks so much for any help. max __________________________________________________ Do You Yahoo!?
