Re: WINS proxy
Hi, I looked at sources of nmbd, and did some experiments with it, and see that that local announcement does not change WINS database. I think that it is bug, and need to be patched. I am talking about samba-2.2.5 now. May be someone could patch it. If it will be do for samba-3.0 or if it is already patched, please notify me.

You need to understand how WINS proxy is designed instead of how you wish it would work for you. Since my last reply, I've gone ahead and done that work for you. Read on... and see that that local announcement does not change WINS database. That is correct behavior. Here's evidence: http://www.microsoft.com/windows2000/en/server/help/sag_WINS_und_Proxies.htm?id=2265 I think that it is bug, and need to be patched. No, it's not a bug. It is working as designed. I am talking about samba-2.2.5 now. May be someone could patch it. If it will be do for samba-3.0 or if it is already patched, please notify me. Before anything gets changed you'll need to convince people that there is a good reason to change it. As for WINS proxy, it is an outdated feature with very limited utility. It was designed by Microsoft to provide support for older implementations which did not understand P-mode. What you are asking for is a new feature which would extend the normal behavior of WINS proxy. So, the real question is this: Why do you want a new proxy service that will convert broadcast-mode registrations into point-to-point registrations and pass them to the NBNS? Are you running B-mode systems that cannot be converted to run in H-mode? How would you avoid sending duplicate enteries for M- and H-mode nodes on the same LAN? If the WINS server sends a Negative Name Registration Response to the client, where will it actually go? Should the WINS server accept name registrations if the header IP does not match the registration IP? There's a lot more to this than shows on the surface.

When a b-node client registers its name, the proxy checks the name against the WINS server database. If the name exists in the WINS database, the proxy might send a negative registration response back to the b-node client attempting to register the name. If WINS proxy check WINS database, why cannot it register b-mode client in it. How would you avoid sending duplicate enteries for M- and H-mode nodes on the same LAN? If WINS proxy knows or gets answer from WINS server, that client and name he asks are in one subnet, then it should not reply to client. If the WINS server sends a Negative Name Registration Response to the client, where will it actually go? It must go to sender (WINS proxy, not its b-mode client). Should the WINS server accept name registrations if the header IP does not match the registration IP? We can say that accept such name registration only from list of hosts, where we write all of our WNIS proxies. Alex.
Re: WINS proxy
Do you mean add them to lmhosts? no - not lmhosts WINS set up the clients to use a WINS server (your samba box) it is on the network properties page. why would you change your domain master browser very often? Ok, this may be will work, but: 1. Clients sometimes changes their name (and workgroup) 2. What I should do with LMB, DMB? - it is changed VERY often, because clients are often do poweroff, reset. - and Samba cannot be LMB for all of workgroups. this doesn't belong on samba-technical now people on samba may be able to provide you a more step-by-step description of how to set up WINS. brad

Re: WINS proxy
Unmanaged clients are unreliable by default. It's not something you can fix. Better you make a reason of that. Simo.

Re: WINS proxy
There is an easy way: if they ask for that you may simply answer that they only need to set your server as wins server. if they are asking something, they may also be willing to do something to have their requests satisfied.

Pleas not that even if they have NT servers, they still have to put the wins host name/address into a box in the cntroll panel. Only if they get their IP addresses from a windows- compatable DHCP server can they get wins server adresses automatically. --dave -- David Collier-Brown, | Always do right.
