Proxy Maintenance Process

[Brian Carpio]

Part of the problem is that during an upgrade our radius application still listens on port 1813 and 1812 and replies to the keepalves (working with development to resolve that since I think that is a problem) so in the mean time I'd like to be able to mark and upgrading server dead then decide when it should be marked alive. 

Thanks for the quick reply!

Brian

  Use "radmin"

  Nope.  Mark it dead.  When it comes back up, the server will figure that out (if Status-Server is enabled)
