Re: [Samba] Home Lan computer browser(s)
For the box that is the samba server, presumably the one that is always on, Just set the os level higher than that of the other boxes. Browse election rules are discussed at: http://www.oreilly.com/catalog/samba2/book/ch07.html Setting os level greater than 32 will insure that your samba box will win the election over all Win boxes. As O'Reilly notes on their site, that book is out of date. Do not use that book, get one of the newer books, unless you aren't running any version of windows newer than Win98 Second Edition. As I understand it, samba by default announces itself as an NT4.9 server on the network. Windows XP announces itself as NT5.2 or greater. Therefore, setting OS level will not matter if there is a Windows XP machine with file print sharing turned on, because 5.2.0 is greater than 4.9.255. Hopefully somebody will correct me if I'm wrong; I haven't actually examined the source code. But I think you have to set announce version = 5.9 if you really want to always win browser elections.

I believe Charlie is correct. The best way to find out what the default value is can be done by executing: testparm -sv | grep announce version you will get the following output: announce version = 4.9 I have been slack in not updating the man page and the default value. What has held me back from changing it is where you have NT4 PDC or BDC configs it should not be changed. I have seen an NT4 network where setting this to 5.0 or higher caused some network admin tools to break. Since there are not many NT4 domains left it may make sense to bump this value up a notch. Some time soon we should increase the default value to something between 5.0 and 5.9. I would like to hear feedback from anyone who is willing to experiment with this value and would like to know if there are any negative consequnces to setting it to a higher value. - John T. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
[Samba] Home Lan computer browser(s)
Reading this list makes me think my questions are child's play for ya'll. */1) //Should I have more than one computer browser on my lan /*/(~16 machines)/*/?/* I'd read someplace that I should have 1 primary and 1 backup computer browser for up to 32 computers and then another backup browser for each additional 32 computers. IF this is true then I'd still like to know how to do this now that I only have 1 winXP machine that I can muck about with but two samba candidates available. I would assume at this point that I'd have to set the winXP machine to NOT be a 'browser'. I'd then need to use the below parms on the two samba machines, with some different settings to have them perform this function. os level = nnn (0 to 255) preferred master = yes/no domain master = yes/no local master = yes/no My problem is I'm not sure how the settings should vary from primary to backup. To have one of the samba machines be primary (let's say the machine I'm calling C20) would these parms work: /*2) If so, can you help me with these settings? */ C20... the primary computer browser? os level = 36 preferred master = yes domain master = yes local master = yes Then on C19... the backup computer browser? os level = 35 preferred master = ?? domain master = ?? local master = ?? I think this would make C20 win an election but would this make them both win an election over the winXP machine should one come on-line with computer browser set on? Are there better settings and / or are some of these not needed for my little world?

I've never heard of it and it seems wrong. As I understand it there is only the master browser role there is no concept of a backup, in the event that the master goes down there is a new election and a new master is chosen. In any case 32 users is ridiculous there are people out there supporting thousands of users, I can guarantee they don't have one server per 32 users. os level = nnn (0 to 255) preferred master = yes/no domain master = yes/no local master = yes/no All of these are fairly well explained in the man page. OS level should be higher for the more reliable/important machine *IF* you have a reason to change it, the defaults will be fine for 99% of cases. Preferred master use this if it is important that one machine is the master (i.e. if you have a domain) don't set it on more than one machine. Domain master is only needed if your network spreads across multiple subnets. You should only have one per workgroup/domain. Local master this is only really needed if you have a machine that you definitely don't want to be in charge of anything, otherwise the default of yes is fine. snip *Michael Heydon - IT Administrator * [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

The answer to your question - NO, there is no need. One of the samba servers on your lan will win the browse election and become the master browser. Each other machine will hold a copy of the browse list. If the master dies, then the normal election rules apply and another box will become the master. The master can serve thousands of clients.

[Samba] home lan
I've read too many articles and posts on domain master browser, computer master browser, NT domain browser, PDC and BDCs, etc. etc. and I've managed to confuse my shrinking brain over this. I apologize in advance if I'm posting a redundant question (I've looked thru archivers best I could) or posting to the wrong place. Here's my local situation - my router (off of cable modem) serves as firewall, a limited DHCP server, etc. etc. all the standard stuff. My little network had about 9 relatively stationary machines that are on 24/7 and another 2 that come and go. The majority of these are headless dedicated number crunchers (it's an affliction called BOINC, another story) these all have static IPs. At one point in time these were nearly all WinXP boxes (exceptions are a couple of #3 son's Gentoo machines whose primary purpose I think is hacking into stuff... but that's also another topic). Late last year I decided to see if you really can teach an old dog new tricks. I undertook converting one of the 'crunchers' to Xubuntu. OK, so now you know I'm a Linux noob. Fast forward to today The network now has about 15 stationary machines and 3 or 4 that come and go. All the 'crunchers' are Xubuntu 64b (v8.04 except one v7.10), one of the desktops is Ubuntu and the Gentoo machines are still here (along with #3 son). There are only two WinXP machines left... a laptop that is owned by my employer and my 'main' desktop(C17). Two of the Xubuntu 'crunchers' (C19 C20) have Samba running in a very simple, un-secure mode to share up some backup drive space and some generic network storage. One of those (C20) also serves as an apt-cacher. What I failed to consider in my conversion to Linux was who was the 'domain master browser' and who the backups were. The winXP desktop is still set to IsDomainMaster = Yes in it's registry and the Computer Browser service is running. But there are no longer any backups in the network that I'm aware of. Yesterday I was VNCing into one of the crunchers and it wouldn't connect. Ran a .bat file I have that pings all the machines and tells me if any don't respond that should. Dang router (192.168.nnn.1) didn't respond... along with some of the other machines. After rebooting cable modem, router, wireless AP - NO CHANGE. For unrelated reasons I happened to crash my desktop (C17, the win XP box) a bit later... when it came back up all was fine and everybody on the network was again consistently pingable, sub 1ms. I'm concluding it's something to do with C17 being the one and only 'computer browser list maintainer' on the network. Maybe a bad conclusion but it still brings up that I think I need to address getting a 'backup computer browser' on the LAN. I read someplace that the winXP can't be 'primary' with Samba as 'backup' but I'm getting mixed signals on that.

Re: [Samba] home lan
Is your overall issue that you can't work with computer names anymore? If so, I'd recommend setting up a real DNS server to fix that. Or if your router allows it, enter static local DNS entries in that (sounds like you don't have that option though).
