How to install Samba on your Amiga? =================================== Before we discuss the details, first a word of warning: Samba is a very complex package and so are the many TCP/IP stacks available for the Amiga. If at first your attempts to install the product do not seem to work, try again. If it does not work the second time and you are certain that you have followed and understood every step outlined in this document, ask someone else for advice. If possible, do not ask the author of this port for advice since he does not understand every little detail of Samba, the TCP/IP stack you are using and in particular how Samba interacts with the rest of your network. I'm not joking. It can go wrong and nobody will be able to tell you why it went wrong. 1. Requirements --------------- This port of Samba 2.0.0 requires an AmiTCP V3 compatible TCP/IP stack. Among these are the original free "AmiTCP 3.0" release, the commercial "AmiTCP 4.x" product, the "AmiTCP Genesis" stack that ships as part of the "NetConnect2" product and the "Miami" and "Miami Deluxe" products. What will not work are the free "AmiTCP 3.x" product or the "INet-225" product. You'll know that Samba does not support your TCP/IP stack if it complains about being unable to open "bsdsocket.library V3", etc. This port has no special CPU type requirements. It should work on any Amiga, provided it is running AmigaOS 2.04 or higher. The next thing this port requires is a lot of memory. If you took a quick look at the programs this package consists of you will know why: some of these programs are almost 1 MByte in size. Don't expect this to run on a machine with less than 4 MBytes of memory installed. Due to how these Samba/Windows networks are usually set up, your computer should sport an Ethernet card, which is properly set up and not suffering from defects such as missing terminators, wrong cabling, wrong connections, etc. You may be able to run Samba via your Amiga's serial port, but honestly, it would be faster to copy the data you wish to transfer with a floppy disk. 2. Preparations --------------- The following text makes a few assumptions on the configuration of your network which may be inappropriate for your system. However, they considerably simplify the instructions. As said before, this is a complex task and we can but only touch the subject. If you need more information, it is recommended that you look at the documentation that came with the package (see the "docs" drawer) or the original Samba distribution package, as available from www.samba.org (and its mirror sites). You must have chosen a proper IP address for your Amiga and all the other machines in the network you want to exchange data with. Do not underestimate this. The weirdest and most difficult to trace errors can result from an improper choice of IP addresses. For example, while 1.2.3.4 and 1.2.3.5 may have worked fine for you so far, they won't continue to work with Samba. If you ended up with such a choice of IP addresses or want to start from scratch with a proper setup, I would recommend that you start with addresses in the range from 192.168.0.1 to 192.168.0.126 which make good sense with a local network. Note that every machine on the network must have a unique address. If you are using a different address for a good reason and are confident that it is a valid class A, B or C address, then you're on your own. You should know what you are doing. If you haven't got any idea what the term "class A address" means in the first place, you should either refer to a good book on this subject or stick with the 192.168.0.x addresses suggested before. Now power up one of the machines on the network you want to exchange data with. If that's a computer running one or another incarnation of Microsoft Windows you may have to make sure that the machine is properly connected to the network and has the necessary TCP/IP, SMB and file sharing software installed. Exactly how this is accomplished is beyond the scope of this document. Really a lot can go wrong here. To keep things simple, the following document will assume that you have already configured such a system and that it's up and running properly. The next thing to do is to perform a simple test to find out whether all the components of the network are working properly. This tests both the cabling, the choice of IP addresses and whether the TCP/IP stack is working. For this test to work out you must know at least one other IP address in your network that corresponds to a TCP/IP stack. Yes, we are going to "ping" that address. It's as simple as that. On the Amiga, start your TCP/IP stack and enter "ping <address>", then press return; you must replace the <address> with the IP address of the other machine on the network whose address you know. Note to users of the Miami TCP/IP stack: use "MiamiPing" in place of "ping". The "ping" command will send some data to the other machine and wait for it to come back. After a few seconds you'll see a statistic which shows how much of the data sent came back and how much got lost on the way. If that number shown is "100%" then the connection is working properly. If the number is "0%" then you have a problem. If the number is somewhere in between 0% and 100% then your networking connections are somewhat flaky. They may still work, but it's not really a good sign to have dropouts like these. If it doesn't work, you're on your own again. Now we are going to install the package and add to your "S:User-Startup" file. Let's say we are going to install the package on your "Work:" partition. Create a drawer on that partition by the name of "Samba", such as by entering the following: MakeDir Work:Samba Next, copy the contents of this package to it. Assuming that the package is stored in the "RAM:amiga_samba_2.0.0" drawer, you would enter the following: Copy RAM:amiga_samba_2.0.0/install Work:Samba all clone Now we need to add a few lines to your "S:User-Startup" file. Open that file with a text editor, such as Ed, and add the following lines to the end of the file: Assign Samba: Work:Samba Path Samba:bin add Almost finished. Now we need to make a few final changes to the Samba configuration file. The configuration file in question is found in the drawer "Work:Samba/lib", as created above. Again, start a text editor and open the file "Work:Samba/lib/smb.conf". Of particular interest are the lines which set the "workgroup" and "domain master" options. The work group option must be set to the name of the work group you want your Amiga to be in on the network. For the sake of simplicity, set this name to the same as on your Windows machine. The "domain master" option can cause trouble if your network already has a domain controller set. This is commonly the case with company networks, in which case you should set this option to "no", or you will cause trouble for your colleagues. If you set up a network at home for your own use and are pretty confident that you don't have a domain controller in it yet, leave this option set to "yes". In any case, save the "smb.conf" file back now and reboot your machine. NOTE: The sample "smb.conf" file included in this package was created for simple, local network access and therefore is not at all secure. It will allow any user on the network to log into your machine and read, write, delete, modify files. If this is just what you wanted, you'll be fine. If this is not all what you had in mind, you may want to read up on the subject of "smb.conf" in the accompanying documentation. 3. Configuring AmiTCP 4.x ------------------------- A few new lines need to be added to three files of the AmiTCP package. You should use a text editor to make the changes. The following files will need to be updated: AmiTCP:db/services The following lines need to be added: netbios-ns 137/udp netbios-dgm 138/udp netbios-ssn 139/tcp swat 901/tcp AmiTCP:db/inetd.conf The following lines need to be added: netbios-ssn stream tcp nowait root Samba:bin/smbd smbd netbios-ns dgram udp wait root Samba:bin/nmbd nmbd swat stream tcp nowait root Samba:bin/swat swat -a AmiTCP:db/passwd The following line needs to be added (NOTE: the <ID> in the follow line must be replaced by a number that does not appear in the "passwd" file yet): pcguest||<ID>|100|PC Guest|SYS:|NewShell And that's all there is to be done. 4. Configuring Miami and Miami Deluxe ------------------------------------- We need to add a few entries to the Miami database, so click on the button labeled "Database" to make the "database" section visible. Next, click on the button that appears at the top of the window until it reads "services". Click on the "Add" button and enter the following: Name: netbios-ns ID: 137 Protocol: udp Repeat this procedure for the following entries: Name: netbios-dgm ID: 138 Protocol: udp Name: netbios-ssn ID: 139 Protocol: tcp Name: swat ID: 901 Protocol: tcp Click on the button that read "services" until it reads "InetD", then click on the "Add" button and enter the following: Service: netbios-ssn Socket: stream Protocol: tcp Wait: nowait User: root Server: Samba:bin/smbd Name: smbd Args: -- Leave this empty -- (The description "-- Leave this empty --" really means that you should enter nothing in this place rather than entering "-- Leave this empty --".) Repeat this procedure for the following entries: Service: netbios-ns Socket: dgram Protocol: udp Wait: wait User: root Server: Samba:bin/nmbd Name: nmbd Args: -- Leave this empty -- Service: swat Socket: stream Protocol: tcp Wait: nowait User: root Server: Samba:bin/swat Name: swat Args: -a Click on the button that read "InetD" until it reads "users", then click on the "Add" button and enter the following: User name: pcguest User id: <ID> Group id: 100 Real name: PC Guest Home dir: SYS: Shell: NewShell In this database, enter a number instead of <ID> that is not found among the other entries currently visible. And that's all there is to be done. You should save your configuration now. 5. Configuring AmiTCP Genesis ----------------------------- In theory, you could use the same steps to configure "AmiTCP Genesis" as with "AmiTCP 4.x". But since "AmiTCP Genesis" has a graphical user interface for the configuration section, we'll use that instead. Begin by starting the "GenesisPrefs" program. When it has started, click on the "Database" label in the list on the left hand side of the window. Next, click on the button at the top of the window which appears near its the right hand side until it reads "Services". Now click on the "Add" button and enter the following data: Name: netbios-ns Port: 137 Protocol: udp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "udp"). Repeat this procedure for the following entries: Name: netbios-dgm Port: 138 Protocol: udp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "udp"). Name: netbios-ssn Port: 139 Protocol: tcp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "tcp"). Name: swat Port: 901 Protocol: tcp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "tcp"). Click on the button that read "Services" until it reads "Inetd", then click on the "Add" button and enter the following: Service: netbios-ssn Enabled: Yes (i.e. there must be a checkmark in this field) User: root Server: Samba:bin/smbd CLI name: smbd Args: -- Leave this empty -- Protocol: tcp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "tcp"). Socket: stream (i.e. below the list with the names "ip", "icmp", etc. in it, there is a button which you should press until it reads "stream"). Wait: nowait (i.e. right above the "Cancel" gadget there is a button which you should press until it reads "nowait"). (The description "-- Leave this empty --" really means that you should enter nothing in this place rather than entering "-- Leave this empty --".) Repeat this procedure for the following entries: Service: netbios-ns Enabled: Yes (i.e. there must be a checkmark in this field) User: root Server: Samba:bin/nmbd CLI name: nmbd Args: -- Leave this empty -- Protocol: udp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "udp"). Socket: dgram (i.e. below the list with the names "ip", "icmp", etc. in it, there is a button which you should press until it reads "dgram"). Wait: wait (i.e. right above the "Cancel" gadget there is a button which you should press until it reads "wait"). Service: swat Enabled: Yes (i.e. there must be a checkmark in this field) User: root Server: Samba:bin/swat CLI name: swat Args: -a Protocol: tcp (i.e. in the list with the names "ip", "icmp", etc. in it, click on the entry by the name of "tcp"). Socket: stream (i.e. below the list with the names "ip", "icmp", etc. in it, there is a button which you should press until it reads "stream"). Wait: nowait (i.e. right above the "Cancel" gadget there is a button which you should press until it reads "nowait"). Click on the "User" label in the list on the left hand side of the window. Next, click on the button "New", then enter the following: User name: pcguest Real Name: PC Guest Home Dir: SYS: Shell: NewShell Disable User: No (i.e. there must not be a checkmark in this field) User ID: <ID> Group ID: 100 In this database, enter a number instead of <ID> that is not found among the other entries currently visible in the user list. When you have entered this data, click on the "Ok" button. That's all there is to be done. Don't forget to save these settings. 6. What else is in the package? ------------------------------- This archive file should also include the source code to the Amiga specific portions of the Samba port (in the "source" directory). To learn more about rebuilding Samba from scratch on your machine, please look at the file located at "source/README". What is probably more important for you are the many files found in the "docs" and "examples" directories. The "examples" directory holds sample configurations for Samba, some of which are applicable to the Amiga port (not all of them are, though). Of particular interest is the "docs" directory which contains a whole load of useful and cryptic information. You might want to read the file "docs/textdocs/DIAGNOSIS.txt" to learn more about diagnosing Samba configuration and network errors. 7. What is not in the package? ------------------------------ There is no support for printing in this Samba port. It might appear to work, but trust me that it does not do this reliably. This functionality has been omitted since I couldn't come up with a halfway plausible way to emulate and configure this feature. Amiga Samba users already have to wrestle with a lot of configuration options and it's all too easy to get things wrong. It doesn't get better if there is another poorly configurable option nobody can really handle. Therefore, stay away from the printing option! The options you can see and operate in the "swat" utility do not all work as you might expect. In particular the options to start, stop and restart the nmbd and smbd daemons are not operational at all. Again, they may appear to do something useful, but they don't. 8. Conclusion ------------- I hope that this brief description is helpful, but as said before, it cannot possibly cover all the details of getting Samba up and running on your Amiga.
