looks like the problem is not with the bird. Although it looks like both hosts are on the same subnet, but are you able to ping each other from either host?

Hi
Your setup looks OK. You could use tcpdump on ens160 to see if there are BGP connection attempts in both directions. Also, is there anything interesting in BIRD logs?
You should also upgrade BIRD, version 1.4.5 is too old.

Remove the old one, install the new one, shutdown the old one, run the new one. BIRD is simple. No docker images, no upgrade procedures. Maria On 06/11/2018 05:35 AM, Isaac HO wrote:

Hi____

Your setup looks OK. You could use tcpdump on ens160 to see if there are BGP connection attempts in both directions. Also, is there anything interesting in BIRD logs?____
__ __
You should also upgrade BIRD, version 1.4.5 is too old.____

On host A, run: nc <ip of host B> 179 <<<"any data you make out from thin air" It should make at least a (failed) log entry on the other side. If not, there is still something rotten in the iptables. Are you really able to ping the other side? Don't you have more than one interface in the same network segment? This doesn't seem to be BIRD's problem at all, you just have somehow garbled network configuration. If you run HTTP server on host B, are you able to connect to it directly from A? Or any other service? M. On 06/14/2018 11:42 AM, Isaac HO wrote:

No, I think either you've got a firewall (iptables etc) running and blocking tcp/179, or you haven't put "listen bgp" into your configuration, so bird is not listening on tcp/179. What is the output of "netstat -lnt"? M
