BGP Error: No listening socket
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 179 - ok. After restart bird see error in/var/log/messges May 12 10:03:01 border-t2 bird: Reconfiguring May 12 10:03:01 border-t2 bird: Enabling protocol bgpfiord May 12 10:03:01 border-t2 bird: Enabling protocol bgpabonent May 12 10:03:01 border-t2 bird: Reconfigured May 12 10:03:01 border-t2 bird: sk_open: bind: Cannot assign requested address May 12 10:03:01 border-t2 bird: BGP: Unable to open listening socket May 12 10:03:01 border-t2 bird: sk_open: bind: Cannot assign requested address May 12 10:03:01 border-t2 bird: BGP: Unable to open listening socket OSPF the protocol works perfectly.

BGP no. ... > I can not understand in any way that happens? What to check up? Do you use 'listen bgp address' config option? Is bird started with root privileges? Isn't there anything other listening on port 179 (can be checked by netstat -anp) ?
