2002-07-09the last WINS update broke self registration when we are a WINSAndrew Tridgell1-7/+0
server. The real problem is all the special cases we had for when we are a wins server as opposed to when we are using a 'real' wins server. This patch removes the special cases. We now accept non-broadcast packets from ourselves and we use ourselves as a wins server when we are one. This gets rid of the special cases and simplifies things quite a bit. It all seems to work, but there are bound to be problems found later. (This used to be commit 3e843d30158d05cdfba716bac7e5c0a75ae7a79c)

2002-06-27The next phase in the WINS rewrite!Andrew Tridgell1-49/+55
We now cope wiith multiple WINS groups and multiple failover servers for release and refresh as well as registration. We also do the regitrations in the same fashion as W2K does, where we don't try to register the next IP in the list for a name until the WINS server has acked the previos IP. This prevents us flooding the WINS server and also seems to make for much more reliable multi-homed registration. I also changed the dead WINS server code to mark pairs of IPs dead, not individual IPs. The idea is that a WINS server might be dead from the point of view of one of our interfaces, but not another, so we need to keep talking to it on one while moving onto a failover WINS server on the other interface. This copes much better with partial LAN outages and weird routing tables. (This used to be commit 313f2c9ff7a513802e4f893324865e70912d419e)
2002-06-26This commit finally gives us multiple wins server groups. We nowAndrew Tridgell1-16/+245
accept an extended syntax for 'wins server' like this: wins server = group1:192.168.2.10 group2:192.168.3.99 group1:192.168.0.1 The tags before the IPs don't mean anything, they are just a way of grouping IPs together. If you use the old syntax (ie. no ':') then an implicit group name of '*' is used. In general I'd recommend people use interface names for the group names, but it doesn't matter much. When we register in nmbd we try to register all our IPs with each group of WINS servers. We keep trying until all of them are registered with every group, falling back to the failover WINS servers for each group as we go. When we do a WINS lookup we try each of the WINS servers for each group. If a WINS server for a group gives a negative answer then we give up on that group and move to the next group. If it times out then we move to the next failover wins server in the group. In either case, if a WINS server doesn't respond then we mark it dead for 10 minutes, to prevent lengthy waits for dead servers. (This used to be commit e125f06058b6b51382cf046b1dbb30728b8aeda5)
2002-06-26made the wins list handling a littler clearerAndrew Tridgell1-9/+5

2002-06-26- completely rewrote the wins_srv.c code. It is now much simpler, andAndrew Tridgell1-303/+90
gives us a good grounding to properly support multiple wins servers for different interfaces (which will be coming soon ...) - fixed our wins registration failover code to actually do failover! We were not trying to register with a secondary wins server at all when the primary was down. We now fallback correctly. - fixed the multi-homed name registration packets so that they work even in a non-connected network (ie. when one of our interfaces is not routable from the wins server. Yes, this really happens in the real world). (This used to be commit a049360d5b0d95a935b06aad43efc17d34de46dc)
2002-01-30Removed version number from file header.Tim Potter1-2/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
2001-11-26Got medieval on another pointless extern. Removed extern struct ipzeroTim Potter1-3/+3
and replaced with two functions: void zero_ip(struct in_adder *ip); BOOL is_zero_ip(struct in_addr ip); (This used to be commit 778f5f77a66cda76348a7c6f64cd63afe2bfe077)

2001-08-26Small changes to get ready for adding WINS failover to smbd and clients.Christopher R. Hertel1-5/+76
My plan is to change the lp_wins_server() function to lp_wins_server_list(). My reason being: With WINS failover the 'wins server' parameter may take a list of WINS server names/IPs instead of just one. If it's a list, then calling lp_wins_server() won't give you what you expect (that is, a single WINS server name or IP). Instead, the functions in wins_srv.c should be used. You can get either the name or IP of the 'current' working WINS server in the list. Chris -)----- (This used to be commit efaa9ef5e72c3748d97e43bba38a0ba47ff3438d)

2000-07-19Instead of handing back a string (which might be a DNS name or an IPChristopher R. Hertel1-33/+85
string), the wins_srv module now hands back a struct in_addr when it's called. It caches the IP address once it has been looked up. The IP is cleared (and must be looked up again) if the 'wins server' parameter is reread, or if the node is marked 'dead'. A dead node will not be re-tried for 10 minutes (per a #define in wins_srv.c). As it was, the code was reading the WINS server name or IP directly from lp_wins_server. That's okay, except that if the value was expressed as a name, then a DNS lookup would be done every time the client wanted to talk to the server. I still need to work out the implications of failover regarding the 'unicast subnet' list. Chris -)----- (This used to be commit 73aa188320fd3bf10b5dfc057323f40aff2c13bd)
2000-07-19First cut toward adding WINS server failover.Christopher R. Hertel1-0/+218
*Note: failover doesn't actually work yet!* It's just that the code I'm adding provides all of the pieces necessary. I do have one big question. Something that I'll have to ask Jeremy, I'm thinkin'. In nmbd/nmbd_subnetdb.c the IP of the WINS server is used to set up the Unicast subnet. ...so what happens if the WINS server changes? My guess is either: a) nothing. b) I'd have to change the unicast subnet entry whenever the WINS server changes. Urq. BTW, the lp_wins_server() function no longer returns the WINS server name or IP. It returns the list of WINS servers entered in smb.conf. To get the currently 'live' WINS server, use the wins_srv() function. Fun, eh?
