In the LISTSERV 1.7 release notes Eric says: Combined with the new DISTRIBUTE path generator (qqv), the ability to enter new links in the LISTSERV configuration without having to alter BITEARN NODES makes it possible to assess the impact of major network changes in advance (before the NODUPD files are released) and avoid the all too frequent "emergency LINKSWT shipment" following a BITEARN NODES update. How do I do this? I'd like to be able to see what various link speeds on redundant paths will do to DIST processing. A 2-minute peak at LISTSERV 191 was uninformative (which doesn't mean the necessary hints aren't there--I just didn't find them). --Brick
