2002-08-16Merge of netbios namecache code from APPLIANCE_HEAD.Tim Potter1-4/+24
Tridge suggested a generic caching mechanism for Samba to avoid the proliferation of little cache files hanging around limpet like in the locks directory. Someone should probably implement this at some stage. (This used to be commit dad31483b3bd1790356ef1e40ac62624a403bce8)
2002-08-05This fixes a number of ADS problems, particularly with netbioslessAndrew Tridgell1-1/+1
setups. - split up the ads structure into logical pieces. This makes it much easier to keep things like the authentication realm and the server realm separate (they can be different). - allow ads callers to specify that no sasl bind should be performed (used by "net ads info" for example) - fix an error with handing ADS_ERROR_SYSTEM() when errno is 0 - completely rewrote the code for finding the LDAP server. Now try DNS methods first, and try all DNS servers returned from the SRV DNS query, sorted by closeness to our interfaces (using the same sort code as we use in replies from WINS servers). This allows us to cope with ADS DCs that are down, and ensures we don't pick one that is on the other side of the country unless absolutely necessary. - recognise dnsRecords as binary when displaying them - cope with the realm not being configured in smb.conf (work it out from the LDAP server) - look at the trustDirection when looking up trusted domains and don't include trusts that trust our domains but we don't trust theirs. - use LDAP to query the alternate (netbios) name for a realm, and make sure that both and long and short forms of the name are accepted by winbindd. Use the short form by default for listing users/groups. - rescan the list of trusted domains every 5 minutes in case new trust relationships are added while winbindd is running - include transient trust relationships (ie. C trusts B, B trusts A, so C trusts A) in winbindd. - don't do a gratuituous node status lookup when finding an ADS DC (we don't need it and it could fail) - remove unused sid_to_distinguished_name function - make sure we find the allternate name of our primary domain when operating with a netbiosless ADS DC (using LDAP to do the lookup) - fixed the rpc trusted domain enumeration to support up to approx 2000 trusted domains (the old limit was 3) - use the IP for the remote_machine (%m) macro when the client doesn't supply us with a name via a netbios session request (eg. port 445) - if the client uses SPNEGO then use the machine name from the SPNEGO auth packet for remote_machine (%m) macro - add new 'net ads workgroup' command to find the netbios workgroup name for a realm (This used to be commit e358d7b24c86a46d8c361b9e32a25d4f71a6dc00)
2002-08-03fixed a bug where we were truncating the returned names in a netbiosAndrew Tridgell1-1/+1
name status query to 14 bytes, so we could not join a DC who had a netbios name of 15 bytes in length. (This used to be commit a7588f21c24dac833f098c48e2337c100cf75ba4)
2002-07-31added 'disable netbios = yes/no' option, default is noAndrew Tridgell1-2/+31
When this option is disabled we should not do *any* netbios operations. You should also not start nmbd at all. I have put initial checks in at the major points we do netbios operations in smbd but there are bound to be more needed. Right now I've disabled all netbios name queries, all WINS lookups and node status queries in smbd and winbindd. I've been testing this option and the most noticable thing is how much more responsive things are! wthout those damn netbios timeouts things certainly are much slicker. (This used to be commit 12e7953bf2497eeb7c0bc6585d9fe58b3aabc240)
2002-07-20Try to fix up warnings - particularly on the IRIX 64 bit compiler (which had aAndrew Bartlett1-1/+1

2002-07-01sort name query responses by how far they are from our interfaceAndrew Tridgell1-0/+41
broadcast addresses. This makes it far more likely that we will try to talk to an interface that is routable from one of our interfaces. (This used to be commit bc1a0506868266088ae585a7a5dcb1ac8ca3474d)
2002-06-27fixed a link problem with global_in_nmbdAndrew Tridgell1-1/+1

2002-06-27The next phase in the WINS rewrite!Andrew Tridgell1-6/+10
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)
2002-06-26resolve_wins() now needs to be a public functionAndrew Tridgell1-2/+2
(This used to be commit 0bce9af615db2eb7e95887ab6b95655d7771dac2)
2002-06-26This commit finally gives us multiple wins server groups. We nowAndrew Tridgell1-43/+68
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)
2002-06-26removed the wins name registration code from libsmbclientAndrew Tridgell1-227/+158
it is *completely* bogus for our client code to be doing wins registrations. Not only is it slow as hell (think about when a wins server is down) but how the heck is going to answer the queries that will later come in for our name? And what happens when libsmbclient sends registrations and nmbd then gets the WACK response from the wins server? we end up losing our name! Name registration is a job for nmbd, not for clients. (This used to be commit 62774923ffdce15eded0f37ba99e33e9cd7a358c)
2002-06-26- completely rewrote the wins_srv.c code. It is now much simpler, andAndrew Tridgell1-3/+3
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)

2001-11-29I think the lookup_pdc_name() should be called lookup_dc_name() and theTim Potter1-21/+22
name_status_find() call here should look up a #1c name instead of #1d. This fixes some bugs currently with BDC authentication in winbindd and in smbd as you can't query the #1d name with the ip address of a BDC. Who is Uncle Tom Cobbley anyway?

2001-08-29Fuss, fuss, fuss...Christopher R. Hertel1-2/+2
Function name_status_query() performs a node status query, so it really should be called "node_status_query()" just to be consistent. Yeah, minor... but it's looking as though an overhaul of namequery.c is in order and I am trying to do the tiny changes that impact other stuff first.

2001-08-29Patched to ensure that it won't break HEAD.Christopher R. Hertel1-6/+10
This isn't the final version, of course, I still need to get WINS failover working. This is just patched so it won't need lp_wins_server() (which I renamed to lp_wins_server_list()). I can't compile just now as something else is broken in HEAD. Let me know if this version of namequery.c causes trouble down the line. Shouldn't, as the changes are very small, but I've been known to rock the boat before. Chris -)----- (This used to be commit 29c6efc9564e51dc28e8434bdc86079c6502d73d)
