You also need the stanzas: protocol kernel; protocol static; and protocol device What do each of these stanzas do? Are they in addition for what I have or a replacement? What part does what I have play? I’m trying to get bird to write a log but no log is written. Here’s what I have so far:

ot@Ampr44182822router:/etc/bird# cat bird.conf log "/var/log/bird.log" all; router id 104.238.141.49; protocol bgp vultr { local as 4288000184; source address 104.238.141.49; import none; export all; graceful restart on; multihop 2; neighbor 169.254.169.254 as 64515; password "password-was-here"; } root@Ampr44182822router:/etc/bird# (I’ll forgo my addresses for now as first it seems bird needs to get running and not die immediately then I need to be able to run: root@Ampr44182822router:/etc/bird# birdc show proto all vultr Have bird actually running, have it be able to connect to its socket, and show that the bgp connection is established. Let’s do this in small understandable steps so others can follow and actually grasp what they are doing. Eventually v6 would be nice but yea, let’s get v4 working first.

If you fire up another VM inside the same Vultr data center, you should be able to ping your 44-net test IP immediately. It may take several hours for your test IP to be accessible globally. > > — > Dave K9DC > > > >> On Apr 4, 2021, at 12:19, Eric Fort via 44Net &lt;44net(a)mailman.ampr.org&gt; wrote: >> >> I’m reviewing this and trying to follow it: >> >> https://www.vultr.com/docs/configuring-bgp-on-vultr >> >> Here is my config files (the vultr examples) I’m running this on debian buster. >> >> Bird.conf: >> >> root@Ampr44182822router:/etc/bird# cat bird.conf >> >> >> router id 104.238.141.49; >> >> protocol bgp vultr >> { >> local as 4288000184; >> source address 104.238.141.49; >> import none; >> export all; >> graceful restart on; >> multihop 2; >> neighbor 169.254.169.254 as 64515; >> password "password-was-here"; >> } >> root@Ampr44182822router:/etc/bird# >> >> Bird6.conf: >> >> root@Ampr44182822router:/etc/bird# cat bird6.conf >> router id 104.238.141.49; >> >> protocol bgp vultr >> { >> local as 4288000184; >> source address 2001:19f0:6001:4c5f:5400:03ff:fe38:d8ce; >> import none; >> export all; >> graceful restart on; >> multihop 2; >> neighbor 2001:19f0:ffff::1 as 64515; >> password "password-was-here"; >> } >> root@Ampr44182822router:/etc/bird# >> >> envvars: >> >> root@Ampr44182822router:/etc/bird# cat envvars >> BIRD_RUN_USER=bird >> BIRD_RUN_GROUP=bird >> #BIRD_ARGS= >> root@Ampr44182822router:/etc/bird# >> >> Bird commands: >> >> root@Ampr44182822router:/etc/bird# birdc show proto all vultr >> Unable to connect to server control socket (/run/bird/bird.ctl): No such file or directory >> root@Ampr44182822router:/etc/bird# >> >> (So it appears bird is not running...... further poking seems to indicate it dies as soon as one tries to start it) >> >> Eric >> Af6ep >> >> Sent using SMTP. >> >>>> On Apr 4, 2021, at 7:51 AM, Scott Nicholas via 44Net &lt;44net(a)mailman.ampr.org&gt; wrote: >>> >>> If bird immediately dies it's the customer config.
