BGP Error: No listening socket

[Владислав Гришин]

Hi!

I have been forced to change customisations of network interfaces on a
server with bird. After modification bird.conf I has checked up availability
of BGP neighbors. Everything is all right. ping ok. telnet <ip of bgp
neighbor> 179 - ok. After restart bird see error in/var/log/messges

OSPF the protocol works perfectly. BGP no.

I can not understand in any way that happens? What to check up?
