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.

is being ignored on sighandler exit. This means we have to have a small
array of fd's, not a single one.

This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.

when looking up the WINS server address.
Please *don't* use lp_wins_server() any more!
The wins_srv_ip() function has the following features:
- If the WINS server was entered as a DNS name then the translation to an
IP address will already have taken place. We used to do this every time
a call to the WINS server was made. Ick.
- The return value of wins_srv_ip() is a struct in_addr. Ready to go.
- When WINS failover is fully implemented, you'll be able to enter a colon-
separated list of WINS servers via the WINS SERVER parameter. Using
lp_wins_server() directly will fail if this syntax is used.

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.

*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?

in a /etc/nsswitch.conf hosts line.
Only tested on RH6.1, but should work on a broad range of Linux
distributions. It could probably be made to work with Solaris pretty
easily.
It does not build by default. Build it with "make nsswitch"
