All computers broadcast a Host Announcement packet, every 180 seconds. If there is configured a domain master browser, why can't they all remember that and talk directly to it? And only if they can't contact it, they should broadcast. Is it me doing something wrong, or Microsoft not doing pretty much anything right? I think it's me, this time... -- Systems and Network Administrator - Delta Romania Phone +4093-267961
Hi Silviu, The broadcasts from the computers are how the master browser determines which computers should be 'aged' out of its browse list. The browse master doesn't go 'looking' for computers, but instead adds a computer to its browse list based on these broadcasts. if it DOESN't get a host announcement for x (don't remember how many) # of periods, it REMOVES the computer from the browse list, so it doesn't keep showing up in network neighborhood after the computer has been shut down, or otherwise removed from the network. There are some good discussions of how browsing works in the various books available on Samba, like 'Special Edition Using Samba' from QUE, and 'Using Samba' from O'Reilly (which is also available in html format at http://www.samba.org/samba/oreilly/using_samba Hope this helps, Don -----Original Message----- From: Silviu Marin-Caea [mailto:silviu@delrom.ro] Sent: Friday, September 14, 2001 8:34 AM To: samba@lists.samba.org Subject: Host Announcement All computers broadcast a Host Announcement packet, every 180 seconds.

Hi Silviu, the short answer to that is "browsing sucks". That's just the way MS implemented it. Sorry. There are probably ways of defeating this, but I have never done it; you can reduce the amount of broadcast traffic by making all the clients and servers use WINS, but this affects name lookup; browsing and browse lists are still going to depend on broadcast... Perhaps someone else on the list has addressed eliminating broadcasts on their network???

If they cannot reach that address, it means the master browser died or changed, and only then broadcast should occur. In some cases bandwidth is not cheap. I have broadcasts traveling a radio link for nothing, and it pisses me off. I know I could use routers, but, firstly, I'm trying hard to get rid of the unnecessary broadcasts. -- Systems and Network Administrator - Delta Romania Phone +4093-267961 -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
