Sorry :-( - - slightly updated sockspy - - - The following was done by Karl Auer (Karl.Auer@anu.edu.au) - - added processing in configuration file of a [printers] section. Allows - connection to any printer specified in /etc/printcap (or the file - specified in the global parameter 'printcap name'). - - added full processing of 'available' flag to configuration file. A - service can now be 'turned off' by specifying 'available = no'. Of - dubious utility. - - added 'printcap =' parameter to [global] section in the configuration - file. This allows the normal /etc/printcap to be bypassed when - checking printer names for dynamic printer connections via [printers]. - - added 'printer name =' parameters to both the [global] section and - services sections of the configuration file. This allows the printer - name only to be set, without having to specify an entire print - command. - - added some synonyms: 'writable' and 'write ok' have the opposite sense - to 'read only'. 'public' may be used instead of 'guest ok'. 'printer' - may be used instead of 'printer name'. 'printable' is the same as - 'print ok'. 'root' may be used instead of 'root dir' or 'root - directory'. - - added lots more detail to the sample configuration file to take - account of the above. - - many minor fixes to internal documentation in the configuration - sources. - - also - Man pages! - - -1.5.32 3/2/94 - - addition of smbd, smbclient and testparm man pages - from Karl Auer - - zombie process fix from lendecke@namu01.gwdg.de - - added capability to nmbd to serve names available - via gethostbyname(). - -1.5.33 3/2/94 - - fixed up getting of netmask so it works on more unix variants - - added -N option to nmbd - - changed GMT diff calculation. need to check it's right for - lots of OSes - - fixed a bug in read_and_X() and chain_reply() chaining now - seems to work correctly - -1.5.34 4/2/94 - - fixed bug in client that meant it couldn't get/put files from WfWg - - fixed a bug in the server that caused lpr to return -1 under sunos - - fixed a few errors in the hosts allow section of the - smb.conf.5 manual page and added examples - -1.5.35 6/2/1994 - - minor bugfix in reduce_name(). - - changed width of "size" in client during a dir - - patches for NEXT (among other things) from lendecke@namu01.gwdg.de - - added -a switch to server, and made default action to append - to log file - - added deadtime options to [global] section for timing out - dead connections to the smbd. - - HPUX changes from Pasi.Kaara@atk.tpo.fi - - made use of unsigned char more consistent - - changed the way of getting the default username and host in the - client - - made LANMAN1 default to on in the client, off in server. - Use -DLANMAN1=1 to make it on in both. - - lots of casts and cleanups for various operating systems - - changes to the Makefile from Karl to auto-instal the man pages - - added a short history of the project to the distribution - -1.5.36 15/2/94 - - fixed minor bug in Debug() (thanks to Pasi.Kaara@atk.tpo.fi) - - fixed bug in server.c so -a wasn't accepted. - - minor fixes to the client - - added hosts file to name server (-H option) - - added -G option for groups to nameserver - - cleanups and additions from Jeremy Allison, taking us - closer to LANMAN1.0.

Some clients seem to use a blank - one if a session setup has succeeded. - - ISC patches from imb@asstdc.scgt.oz.au - - the client now tries to do name registration using a unicast. - Let me know if this helps anyone. - - tried to add a "contributed" line to each OS in the Makefile. - -1.5.39 18/2/94 - - fixed silly C code that only worked with some compilers - - fixed another silly bug in nameserv.c that caused it to seg fault - -1.5.40 21/2/94 - - removed the from (IP) message so people don't worry about 0.0.0.0, - it's redundant anyway. - - changed the client so the crypt key isn't printed - - changed the structure of switch_message() to use a list of functions. - This improves the debug info. - - made SMBopen ignore supplied attribute as per X/Open spec - - made SMBopen fail if file doesn't exist in all cases.

So when nmbd sends out a NBT packet as part of some complex -processing, it adds to a linked list the information required to -continue the processing when the reply comes in (or it times -out).

WINS doesn't -have much to do with browsing, it is the WAN varient of name -resolution. The name resolution and browsing functions of a netbios -network are almost entirely separate. Both grew out of systems that -could only be used on local networks. - -To adapt them to WANs, WINS was added for name resolution, and "domain -master browsers" were added for browse lists.

*************************************************************************/ - -this function is responsible for replying to a NetBIOS name query. - -there are two kinds of name queries: directed, and broadcast. directed -queries are usually sent to samba in its WINS capacity. such hosts are -termed 'point-to-point' hosts. broadcast queries are usually sent from -'broadcast' or 'mixed' hosts. - -broadcasting is used by either older NetBIOS hosts, new NetBIOS hosts that -have not had WINS capabilities added and new NetBIOS hosts that think the -WINS server has died. - -the samba NetBIOS name database is divided into sections, on a -per-subnet basis. there is also a WINS NetBIOS name database, and for -convenience this is added as a pseudo-subnet with the ip address of -255.255.255.255. - -the local subnet NetBIOS name databases only contain samba's names. -the reason for this is that if a broadcast query is received, a NetBIOS -hosts is only expected to respond if that query is for one of its own -names (the exception to this is if a host is configured as a 'proxy' -server, in which case, samba should redirect the query to another WINS -server). - -the WINS pseudo-subnet NetBIOS database contains all NetBIOS names -that are not 'special browser' type names (regarding this i am a -_bit_ confused :-). names of type 0x01, 0x1d and 0x1e i consider to -be 'special browser' names. at the moment. maybe. - -the type of search to be initiated is determined. if the NetBIOS name -type is a non-special-browser name, then the WINS database is included -in the search. - -if the name is not a special browser name, then we need to find the -right subnet that the query came from. this is done using -find_req_subnet(). this also has the benefit of stopping any queries -from subnets that samba does not know about. - -if the query is a broadcast query, then the database of the local subnet -is included in the search. - -the name is then searched for in the appropriate NetBIOS data structures. -if it is found, then we need to check whether it is appropriate for us -to reply to such a query. - -we will only reply if the query is a directed query, the name belongs to -samba on that subnet, or the name is a domain master browser type, -or we're doing replies on behalf of hosts on subnets not known to the -host issuing the query. in the latter instance, it would be appropriate -if samba is using a WINS server for it to forward the name query on to -this WINS server. - -reply_name_query() then takes note of all the information that is -needed to construct a reply to the caller. a negative reply (if the -name is unknown to samba) or a positive reply (the name is known to -samba) is then issued. - - -/************************************************************************* - reply_name_status() - *************************************************************************/ - -this function is responsible for constructing a reply to a NetBIOS -name status query. this response contains all samba's NetBIOS names -on the subnet that the query came in from. - -a reply will only be made if the NetBIOS name being queried exists. - -see rfc1001.txt and rfc1002.txt for details of the name status reply. - - -/************************************************************************* - reply_name_reg() - *************************************************************************/ - -this function is responsible for updating the NetBIOS name database -from registration packets sent out by hosts wishing to register a -name, and for informing them, if necessary, if this is acceptable -or not. - -name registration can be done by broadcast or by point-to-point, -i.e the registration is sent directly to samba in its capacity as -a WINS server. - -if the name registration is done by broadcast (see rfc1001.txt 15.2.1), -then samba's involvement in replying is limited to whether that name -is owned by samba or not, on the relevant subnet. - -if the name registration is done point-to-point (see rfc1001.txt 15.2.2) -then samba will first need to check its WINS name database records and -proceed accordingly. - -samba looks for the appropriate subnet record that the registration -should be added to / checked against, using find_req_subnet(). - -next, the name is searched for in the local database or the WINS -database as appropriate. - -if the name is not found, then it is added to the NetBIOS name database, -using add_netbios_entry(), which may choose not to add the name (not -that this affects the registration of the name on the network in any way). -it will only add names to the WINS database, and even then it will only -add non-special-browser type names. - -if the name is found, then samba must decide whether to accept the name -or not. a group name is always added. for unique names, further checks -need to be carried out. - -firstly, if the name in the database is one of samba's names, or if the -name in the database is a group name, then it cannot be added as a unique -name belonging to someone else. it is therefore rejected. - -secondly, if the ip address of the name being registered does not match -against the ip in the database, then the unique name may belong to -someone else. a check needs to be carried out with the owner in case -they still wish to keep this name. a detailed discussion of what action -to take is in rfc1001.txt 15.2.2.2 and 15.2.2.3. - -samba currently implements non-secured WINS, whereupon the responsibility -for checking the name is passed on to the host doing the registration. -rfc1001.txt refers to this as an END-NODE CHALLENGE REGISTRATION RESPONSE. -(samba itself cannot yet cope with receiving such responses if it -registers its names with another WINS server). - -having decided what kind of response to send (if any - acceptance of -name registrations by broadcast is implicit), samba will send either a -positive or negative NAME REGISTRATION RESPONSE, or an END-NODE CHALLENGE -REGISTRATION RESPONSE to the host that initially sent the registration. - -whew. - - -/************************************************************************* - reply_name_release() - *************************************************************************/ - -this function is responsible for removing a NetBIOS name from the -database when a server sends a release packet. - -samba looks for the appropriate subnet record that the release should -be removed from, using find_req_subnet(). next, the name is searched -for in the local database or the WINS database as appropriate. - -if the name is found, it is removed from the database and a -positive reply is sent confirming this. if the name is not -found, a negative reply is sent. - -a reply is _not_ sent if the release was done by broadcast: the -release is implicit, and we should be grateful that they bothered -to tell us. if the release was done by directed packet, then -we deal with it as a WINS server and must reply (pos / neg). - -at present, the criteria for removing a name have yet to be -developed / experimented with. at present, the only flags that -are checked are the NetBIOS flags. - - -/************************************************************************* - send_name_response() - *************************************************************************/ - -this function is a wrap around reply_netbios_packet(). it sends -a response to a name registration or release packet, minimising -the function parameters needed to do this. - -if the function is called with the parameter 'success' set to -True, then a positive response (to the registration or release) -is made (see rfc1002.txt 4.2.5 and 4.2.10). if this parameter -is False, then a negative response is issued (see rfc1002.txt -4.2.6 and 4.2.11) - -if the function is called with a registration code, and the -parameter 'recurse' is False, then an End-Node Challenge -Registration response is issued (see rfc1002.txt 4.2.7) - -note: this function could also easily be used for name conflict -demand (see rfc1002.txt 4.2.8). -

Basically these -"master announce" datagrams are the way that separate netbios subnets -are linked together to form a complete browse net. The way it works is -that the local master decides it is going to inform the domain master -of its presence, then sends this master announce to the domain -master.
