KDC fails to start

[securenix]

Hi,

I run "/etc/init.d/krb5kdc start" to start kdc but it does not function 
well. No KDC runs and no port is open.

The log file says:

krb5kdc: No such device - Cannot bind server socket to port 750 address 
fe80::20b:....
krb5kdc: No such device - Cannot bind server socket to port 750 address 
fe80::20b:....

Google actually did not help  very much. Any idea for the solution?

I use Fedora Core 2 with kernel 2.6.

Thanks
