Re: frost is moving



Hi Jeff,

Thank you for the heads up and the update regarding the stats.  I'll
discuss frost's relocation with my team.  I know that having well
connected sites in the East was important for us, so we may rethink the
topology a bit.  

Would you please send me frost's ldmd.conf file so I can see who is
allowed to connect?  And, would you please grep through your logs for
"Connect" so I can see who is actually connecting?

Thanks again!

Anne
