I don't have any idea what they turned on. The equipment was all managed and I didn't know there was a difference until I came to work one day and couldn't get to one of my computers, which was on a different network, that was collecting realtime manufacturing information. We went storming into the network guy's office and told him that he had broken the manufacturing networks. If I couldn't get in, they couldn't get out. He remarked that they had changed some equipment over the weekend and because of the "keyword sensitivity training" he had received in the past when they had done something like that, he dropped everything to look into it. A few minutes later he came in and asked me to try what I needed to do again and it worked. Asked for an explaination, He spit out some networking jargon and walked back to his office. Enabling plant wide Netbeui browsing was once described to me as being only one step better than enabling Apple talk or Novell over a major tcp/ip network. They are all supposed to be exceedingly chatty and enabling them plant wide supposedly required someone out of their friendly minds. In the somewhat distant past, Microsoft's Master browser's have been known to create broadcast storms, which could effectively stop a network if there were enough of them around. If you pass the packets they emit during the discovery process to your entire operation, you are in trouble. I have never seen a broadcast storm because I was never involved in monitoring the networks I used. The only thing I ever measured was the transfer rate for an FTP session between a computer on a tcp/ip network to a computer using both protocols on a Novell network. In that situation, the transfers typically ran from 1/3 to 1/4 the speed of the same file being transfered over a pure tcp/ip network. I always assumed that something was misconfigured. We adjusted timeouts to compensate for the lower throughput in that situation. This was all pre-WWW and all of the comments are probably meaningless at this point. -- Kent Stewart Richland, WA To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
