Since the PUT LINKSWT FILE on the backbone worked correctly, I will attempt a PUT PEERS NAMES (still on the backbone), in the hope to *eventually* define a few more servers. I hope not to cause any problem with DISTRIBUTE -- should this happen I would reinstate the old PEERS NAMES which I have just retrieved from EB0UB011 and stored on my disk. If this is successful I will proceed to add all the remaining servers next week -- after re-contacting their owners to make sure everything is still ok with them. Eric
