[Centos] Dag Errors

[psavoie1783 at rogers.com (Phil Savoie)]

Hi All,

I am getting the following errors from a 'yum update' from

http://apt.sw.be/redhat/el4/en/$basearch/dag/

 warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 6b8d79e6
public key not available for nmap-frontend-3.81-1.2.el4.rf.i386.rpm

Any idea as to get the dag signature?

Phil
