Hello! Thank you for your report. The systemd unit file should definitely be Type=forking and without -f for BIRD. Will fix that soon also in v2. The bad fd itself was caused by an invalid pointer usage caused by missing else. Here you can download new packages to check it for yourself.

Re: BIRD 3.0alpha2

There shall be a "threads N;" top-level config directive. We have probably not published build docs, we'll fix that for the next release, sorry for that. Kernel sync is a hard question, we have to discuss it internally first. The most viable way is probably just offloading it into a worker

Hello! Thank you for giving us the opportunity to test. So far I spotted only few flaws: Thank you for testing and reporting. Your inputs are appreciated. 1. Routes with unknown attributes which are abusively extending/violating BGP protocol are still rejected. rtr bird[98404]: bgp_r_v4:

Re: question regarding table lookups

Hello! These features are not present. I'm now merging (into v3) a feature allowing to check for routes in different tables but without parameters. All in all, these features are not even in our backlog as they are surprisingly complex below the surface. Anyway, if there is a demand for this…

That's fishy. Will try to reproduce and find out what is behind. Maria On 5/15/23 13:32, Tim Weippert via Bird-users wrote: Hi Maria, i think the confusion part is, that it works on CLI in a "symmetric" way but not in a function, that was my biggest questionmark :) regards, tim On Mon, May

Hello! No, we don't publish Docker images. We'll consider it, yet I can't promise any timeline now. We are used to different methods of virtualization and Docker has been under our radar. Best Regards, Maria On 12 May 2023 19:34:52 CEST, Nico Schottelius via Bird-users wrote: > >Hello

Re: Doc suggestion - clarifying behaviour when routes are moving between protocols

Hello Mark, you are having a lot of useful suggestions. There are even more thoughts alike yours, regarding documentation. And indeed you are right that our documentation is kinda good as a reference manual but it kinda sucks if you are a newbie. The thing is, we have quite a long backlog

Re: Add random number

Hello! No, it's not possible and it makes the filters non-deterministic which would break a critical invariant in BIRD's internal algorithms. If you better clarify what you are trying to achieve, we may find another way for you to do it, or at least convert it to a viable feature request.

Re: Adding support for an experimental IPv6 Hop By Hop Extension header

Hello Paul, I'm afraid that this topic may be out of BIRD's primary scope. If I assess your needs correctly, this is maybe more to do in NetworkManager or something like that, or maybe even in-kernel. But I may be wrong. If you could describe what exactly you're trying to achieve (even
