Unable to open rtnetlink socket ....

[Jendřejčík Rostislav]

Hi all .... trying to install the BIRD on my RedHat 6.2 (2.2.18) from
RPM and later by "make ...."  Everything looks fine , but I still can't
run the daemon. Allways with the same error:

[root at fw /etc]# /etc/rc.d/init.d/bird start
Starting BIRD: 11-09-2001 13:58:11 <FATAL> Unable to open rtnetlink
socket: Address family not supported by protocol

What's wrong? Can you help me please? 

Thank you very much

Ross
