Hello fellow bird users,
with bird 2.0.12 I am currently getting an "Socket: Permission denied"
error messages when trying to establish a specific IPv6 iBGP session.
The funny thing is that another connection works perfectly.
The BGP block that fails is:
--------------------------------------------------------------------------------
protocol bgp serverXX {
local as xx;
neighbor 2a0a:...::44 as xx;
direct;
ipv6 {
import all;
export all;
};
ipv4 {
import all;
export all;
};
}
--------------------------------------------------------------------------------
Resulting into:
bird> show protocols all serverXX
Name Proto Table State Since Info
serverXX BGP --- start 12:18:52.466 Active Socket:
Permission denied
BGP state: Active
Neighbor address: 2a0a:..::44
Neighbor AS: xx
Local AS: xx
Connect delay: 2.961/5
Last error: Socket: Permission denied
Channel ipv6
State: DOWN
Table: master6
Preference: 100
Input filter: ACCEPT
Output filter: ACCEPT
Channel ipv4
State: DOWN
Table: master4
Preference: 100
Input filter: ACCEPT
Output filter: ACCEPT
--------------------------------------------------------------------------------
An almost identical iBGP session is established without problems:
--------------------------------------------------------------------------------
protocol bgp routerZZ {
local as xx;
neighbor 2a0a:..::6 as xx;
direct;
ipv6 {
import all;
export all;
};
ipv4 {
import all;
export all;
};
}
--------------------------------------------------------------------------------
Obviously the IPs are different, but I am really puzzled at to what
causes this. It's bird 2.0.12 running on Linux, iptables/ip6tables are
not having any rules.
Interestingly the peer on the other side has exactly the same error.
Does anyone have a hint on what might be wrong here?
Best regards,
Nico
