A single IDE disk will do still fewer. If the disks are independent, or striped together in a RAID 1 configuration, they will each peak out at 400 to 560KB/s and will scale linearly as you add more.

Our solution is to add five more disks. This gives us more throughput on the disks than on the Ethernet, so then the Ethernet becomes the problem. Consequently, as we continue to expand, we go back and forth several times between these two. As you add disks, CPUs, and network cards, the bottleneck moves. Essentially, the strategy is to add more equipment to try to avoid each bottleneck until you reach your target performance, or (unfortunately) you either can't add any more or run out of money.</p><P CLASS="para"> -Our experience bears out this kind of calculation; a large SPARC 10 file server that one author maintained was quite capable of saturating an Ethernet plus about a third of an FDDI ring when using two processors. It did nearly as well with a single processor, albeit with a fast operating system and judicious over-optimization.</p><P CLASS="para"> -The same process applies to other brands of purpose-designed servers. We found the same rules applied to DECstation 2100s as to the newest Alphas or Compaqs, old MIPS 3350s and new SGI O2s. In general, a machine offering multi-CPU server configurations will have enough bus bandwidth and CPU power to reliably bottleneck on hard disk I/O when doing file service. As one would hope, considering the cost!</p></div><DIV CLASS="sect2"> -<H3 CLASS="sect2"> -<A CLASS="title" NAME="appb-pgfId-948730"> -B.3.4 How Many Clients can Samba Handle?</a></h3><P CLASS="para"> -Well, that depends entirely on how much data each user consumes. A small server with three SCSI-1 disks, which can serve about 960KB/s of data, will support between 36 and 80 clients in an ordinary office environment where they are typically loading, and saving equal-sized spreadsheets or word processing documents (36 clients × 2.3 transfers/second × 12k file 1 MB/s).</p><P CLASS="para"> -On the same server in a development environment with programmers running a fairly heavy edit-compile-test cycle, one can easily see requests for 1 MB/s, limiting the server to 25 or fewer clients. To take this a bit further, an imaging system whose clients each require 10 MB/s will perform poorly no matter how big a server is if they're all on a 10 MB/s Ethernet. And so on. </p><P CLASS="para"> -If you don't know how much data an average user consumes, you can size your Samba servers by patterning them after existing NFS, Netware, or LAN Manager servers. You should be especially careful that the new servers have as many disks and disk controllers as the ones you've copied. This technique is appropriately called "punt and hope."</p><P CLASS="para"> -If you know how many clients an existing server can support, you're in <EM CLASS="emphasis"> -much</em> better shape. You can analyze the server to see what its maximum capacity is and use that to estimate how much data they must be demanding. For example, if serving home directories to 30 PCs from a PC server with two IDE disks is just too slow, and 25 clients is about right, then you can safely assume you're bottlenecked on Ethernet I/O (approximately 375KB) rather than disk I/O (up to 640KB). If so, you can then conclude that the clients are demanding 15 (that is, 375/25)KB/s on average.</p><P CLASS="para"> -Supporting a new lab of 75 clients will mean you'll need 1,125KB/s, spread over multiple (preferably three) Ethernets, and a server with at least three 7200 RPM disks and a CPU capable of keeping up. These requirements can be met by a Pentium 133 or above with the bus architecture to drive them all at full speed (e.g., PCI).</p><P CLASS="para"> -A custom-built PC server or a multiprocessor-capable workstation like a Sun Sparc, a DEC/Compaq Alpha, an SGI, or the like, would scale up easier, as would a machine with fast Ethernet, plus a switching hub to drive the client machines on individual 10 MB/s Ethernets.</p><DIV CLASS="sect3"> -<H4 CLASS="sect3"> -<A CLASS="title" NAME="appb-pgfId-948739"> -B.3.4.1 How to guess</a></h4><P CLASS="para"> -If you have no idea at all what you need, the best thing is to try to guess based on someone else's experience. Each individual client machine can average from less than 1 I/O per second (normal PC or Mac used for sales/accounting) to as much as 4 (fast workstation using large applications). A fast workstation running a compiler can happily average 3-4 MB/s in data transfer requests, and an imaging system can demand even more. </p><P CLASS="para"> -Our recommendation? Spy on someone with a similar configuration and try to estimate their bandwidth requirements from their bottlenecks and the volume of the screams from their users. We also recommend Brian Wong's <CITE CLASS="citetitle"> -Configuration and Capacity Planning for Solaris Servers</cite>. While he uses Sun Solaris foremost in his examples, his bottlenecks are disks and network cards, which are common among all the major vendors.

If Samba is as good as or better than FTP, and if there aren't any individual test runs that are much different from the average, you have a well-configured system. If loopback isn't much faster than anything else, you have a problem with your TCP/IP software. If both FTP and Samba are slow, you probably have a problem with your networking: a faulty Ethernet card will produce this, as will accidentally setting an Ethernet card to half-duplex when it's not connected to a half-duplex hub.

Learning the Samba</h1> -<p>If you are a typical system administrator, then you know what it means to be <i>swamped</i> with work. Your daily routine is filled with endless hardware incompatibility issues, system outages, data backup problems, and a steady stream of angry users. So adding another program to the mix of tools that you have to maintain may sound a bit perplexing. However, if you're determined to reduce the complexity of your work environment, as well as the workload of keeping it running smoothly, Samba may be the tool you've been waiting for.</p> - -<p>A case in point: one of the authors of this book used to look after 70 Unix developers sharing 5 Unix servers. His neighbor administered 20 Windows 3.1 users and 5 OS/2 and Windows NT servers. To put it mildly, the Windows 3.1 administrator was swamped. When he finally left - and the domain controller melted - Samba was brought to the rescue. Our author quickly replaced the Windows NT and OS/2 servers with Samba running on a Unix server, and eventually bought PCs for most of the company developers. However, he did the latter without hiring a new PC administrator; the administrator now manages one centralized Unix application instead of fifty distributed PCs. </p> - -<p>If you know you're facing a problem with your network and you're sure there is a better way, we encourage you to start reading this book. Or, if you've heard about Samba and you want to see what it can do for you, this is also the place to start. We'll get you started on the path to understanding Samba and its potential. Before long, you can provide Unix services to all your Windows machines - all without spending tons of extra time or money. Sound enticing? Great, then let's get started.</p> - -<a name="s1"></a> -<h2 id="ch01-28119">1.1 What is Samba?</h2> - -<p>Samba is a suite of Unix applications that speak the SMB (Server Message Block) protocol. Many operating systems, including Windows and OS/2, use SMB to perform client-server networking. By supporting this protocol, Samba allows Unix servers to get in on the action, communicating with the same networking protocol as Microsoft Windows products. Thus, a Samba-enabled Unix machine can masquerade as a server on your Microsoft network and offer the following services:</p> - -<ul> -<li id="ch01-pgfId-940463"> - -<p>Share one or more filesystems</p> - -</li> -<li id="ch01-pgfId-940464"> - -<p>Share printers installed on both the server and its clients</p> - -</li> -<li id="ch01-pgfId-940465"> - -<p>Assist clients with Network Neighborhood browsing</p> - -</li> -<li id="ch01-pgfId-940489"> - -<p>Authenticate clients logging onto a Windows domain</p> - -</li> -<li id="ch01-pgfId-940472"> - -<p>Provide or assist with WINS name server resolution</p> - -</li> -</ul> - -<p>Samba is the brainchild of Andrew Tridgell, who currently heads the Samba development team from his home of Canberra, Australia. The project was born in 1991 when Andrew created a fileserver program for his local network that supported an odd DEC protocol from Digital Pathworks. Although he didn't know it at the time, that protocol later turned out to be SMB. A few years later, he expanded upon his custom-made SMB server and began distributing it as a product on the Internet under the name SMB Server. However, Andrew couldn't keep that name - it already belonged to another company's product - so he tried the following Unix renaming approach:</p> - -<pre> -grep -i 's.*m.*b' /usr/dict/words </pre> - -<p>And the response was:</p> - -<Pre> -salmonberry samba sawtimber scramble</pre> - -<p>Thus, the name "Samba" was born.<footnote id="ch01-pgfId-946532"> - -<p>Which is a good thing, because our marketing people highly doubt you would have picked up a book called "Using Salmonberry"!</p> - -</footnote></p> - -<p>Today, the Samba suite revolves around a pair of Unix daemons that provide shared resources - or <i>shares</i> - to SMB clients on the network. (Shares are sometimes called s<i>ervices</i> as well.) These daemons are:</p> - -<dl> -<dt>smbd</dt> -<dd> - -<p id="ch01-pgfId-949804">A daemon that allows file and printer sharing on an SMB network and provides authentication and authorization for SMB clients.</p> - -</dd> - -<dt>nmbd</dt> -<dd> - -<p id="ch01-pgfId-949805">A daemon that looks after the Windows Internet Name Service (WINS), and assists with browsing.</p> - -</dd> -</dl> - -<p>Samba is currently maintained and extended by a group of volunteers under the active supervision of Andrew Tridgell. Like the Linux operating system, Samba is considered <i>Open Source software </i>(OSS) by its authors, and is distributed under the GNU General Public License (GPL). Since its inception, development of Samba has been sponsored in part by the Australian National University, where Andrew Tridgell earned his Ph.D.<a href = "#footnote"> [1]</a> - In addition, some development has been sponsored by independent vendors such as Whistle and SGI. It is a true testament to Samba that both commercial and non-commercial entities are prepared to spend money to support an Open Source effort.</p> -<blockquote><a name="footnote"> -<p>[1] At the time of this printing, Andrew had completed his Ph.D. work and had joined San Francisco-based LinuxCare.</p> -</blockquote> -<p>Microsoft has also contributed materially by putting forward its definition of SMB and the Internet-savvy Common Internet File System (CIFS), as a public Request for Comments (RFC), a standards document. The CIFS protocol is Microsoft's renaming of future versions of the SMB protocol that will be used in Windows products - the two terms can be used interchangeably in this book. Hence, you will often see the protocol written as "SMB/CIFS."</p> </p></div></div></div></blockquote> -<div> -<center> -<hr noshade size=1><TABLE WIDTH="515" BORDER="0" CELLSPACING="0" CELLPADDING="0"> -<TR> -<TD ALIGN="LEFT" VALIGN="TOP" WIDTH="172"> - -</td><TD ALIGN="CENTER" VALIGN="TOP" WIDTH="171"> -<A CLASS="book" HREF="index.html" TITLE=""> -<IMG SRC="gifs/txthome.gif" ALT="" BORDER="0"></a></td><TD ALIGN="RIGHT" VALIGN="TOP" WIDTH="172"> -<A CLASS="sect1" HREF="ch01_02.html" TITLE="1.2 What Can Samba Do For Me?"> -<IMG SRC="gifs/txtnexta.gif" ALT="Next: 1.2 What Can Samba Do For Me?"

If you are using Windows 98 or Windows NT Service Pack 3 or above, this is probably because the client is sending encrypted passwords instead of plaintext passwords. You can remedy this situation by performing two steps on the Samba server. First, add the following entry to the <CODE CLASS="literal"> -[global]</code> section of your Samba configuration file: <CODE CLASS="literal"> -encrypt password=yes</code>. Second, find the <I CLASS="filename"> -smbpasswd</i> program on the samba server (it is located in <I CLASS="filename"> -/usr/local/samba/bin</i> by default) and use it to add an entry to Samba's encrypted password database. For example, to add user <CODE CLASS="literal"> -steve</code> to Samba's encrypted password database, type <CODE CLASS="replaceable"> -<I> -smbpasswd -a steve</i></code>. The first time you enter this password, the program will output an error message indicating that the password database does not exist; it will then create the database, which is typically stored in <I CLASS="filename"> -/usr/local/samba/private/smbpasswd</i>.</p></blockquote><P CLASS="para"> -If you don't see the server listed, don't panic.

Let's look at the <CODE CLASS="literal"> -interfaces</code> option first. Samba, by default, sends data only from the primary network interface, which in our example is the 192.168.220.100 subnet. If we would like it to send data to more than that one interface, we need to specify the complete list with the <CODE CLASS="literal"> -interfaces</code> option. In the previous example, we've bound Samba to interface with both subnets (192.168.220 and 134.213.233) on which the machine is operating by specifying the other network interface address: 134.213.233.100.

Note that this is different from the <CODE CLASS="literal"> -hosts</code> <CODE CLASS="literal"> -allow</code> and <CODE CLASS="literal"> -hosts</code> <CODE CLASS="literal"> -deny</code> options, which prevent machines from making connections to services, but not from receiving broadcast messages. Using the <CODE CLASS="literal"> -bind</code> <CODE CLASS="literal"> -interfaces</code> <CODE CLASS="literal"> -only</code> option is a way to shut out even datagrams from foreign subnets from being received by the Samba server. In addition, it instructs the <EM CLASS="emphasis"> -smbd </em>process to bind to only the interface list given by the <EM CLASS="emphasis"> -interfaces</em> option.

Mapping these bits, however, has an unfortunate side-effect: if a Windows user stores a file in a Samba share, and you view it on Unix with the <CODE CLASS="literal"> -ls</code> <CODE CLASS="literal"> --al</code> command, some of the executable bits won't mean what you'd expect them to.</p><P CLASS="para"> -Three Samba options decide whether the bits are mapped: <CODE CLASS="literal"> -map</code> <CODE CLASS="literal"> -archive</code>, <CODE CLASS="literal"> -map</code> <CODE CLASS="literal"> -system</code>, and <CODE CLASS="literal"> -map</code> <CODE CLASS="literal"> -hidden</code>.

File creation masks (or <I CLASS="firstterm"> -umasks</i>) help to define the permissions a file or directory will receive at the time it is created. In Unix, this means that you can control what permissions a file or directory does not have when it is created. For files accessed from Windows, this means you can disable the read-only, archive, system, and hidden attributes of a file as well.</p><P CLASS="para"> -For example, the <CODE CLASS="literal"> -create</code> <CODE CLASS="literal"> -mask</code> option will force the permissions of a file created by a Windows client to be at most 744:</p><PRE CLASS="programlisting"> -[data] - path = /home/samba/data - browseable = yes - guest ok = yes - writeable = yes - create mask = 744</pre><P CLASS="para"> -while the <CODE CLASS="literal"> -directory</code> <CODE CLASS="literal"> -mask</code> option shown here will force the permissions of a newly created directory to be at most 755:</p><PRE CLASS="programlisting"> -[data] - path = /home/samba/data - browseable = yes - guest ok = yes - writeable = yes - directory mask = 755</pre><P CLASS="para"> -Alternatively, you can also force various bits with the <CODE CLASS="literal"> -force</code> <CODE CLASS="literal"> -create</code> <CODE CLASS="literal"> -mode</code> and <CODE CLASS="literal"> -force</code> <CODE CLASS="literal"> -directory</code> <CODE CLASS="literal"> -mode</code> options. These options will perform a logical OR against the file and directory creation masks, ensuring that those bits that are specified will always be set. You would typically set these options globally in order to ensure that group and world read/write permissions have been set appropriately for new files or directories in each share.</p><P CLASS="para"> -In the same spirit, if you wish to explicitly set the Unix user and group attributes of a file that is created on the Windows side, you can use the <CODE CLASS="literal"> -force</code> <CODE CLASS="literal"> -user</code> and <CODE CLASS="literal"> -force</code> <CODE CLASS="literal"> -group</code> options. For example:</p><PRE CLASS="programlisting"> -[data] - path = /home/samba/data - browseable = yes - guest ok = yes - writeable = yes - - create mask = 744 - directory mask = 755 - force user = joe - force group = accounting</pre><P CLASS="para"> -These options actually assign a static Unix user and group to each connection that is made to a share.

These options are frequently used for their side effects of assigning a specific user and group to each new file or directory that is created in a share. Use these options with discretion.</p><P CLASS="para"> -Finally, one of the capabilities of Unix that DOS lacks is the ability to delete a read-only file from a writable directory. In Unix, if a directory is writable, a read-only file in that directory can still be removed. This could permit you to delete files in any of your directories, even if the file was left by someone else.</p><P CLASS="para"> -DOS filesystems are not designed for multiple users, and so its designers decided that read-only means "protected against accidental change, including deletion," rather than "protected against some other user on a single-user machine." So the designers of DOS prohibited removal of a read-only file. Even today, Windows file systems exhibit the same behavior.</p><P CLASS="para"> -Normally, this is harmless. Windows programs don't try to remove read-only files because they know it's a bad idea. However, a number of source-code control programs - which were first written for Unix - run on Windows and require the ability to delete read-only files. Samba permits this behavior with the <CODE CLASS="literal"> -delete</code> <CODE CLASS="literal"> -readonly</code> option.

To prevent this, most operating systems use <I CLASS="firstterm"> -locks</i> to guarantee that only one process can write to a file at a time. Operating systems traditionally lock entire files, although newer ones allow a range of bytes within a file to be locked. If another process attempts to write to a file (or section of one) that is already locked, it will receive an error from the operating system and will wait until the lock is released.</p><P CLASS="para"> -Samba supports the standard DOS and NT filesystem (deny-mode) locking requests, which allow only one process to write to an entire file on a server at a give time, as well as byte-range locking.

An opportunistic lock, however, is not a replacement for a standard deny-mode lock.

This is because each of those Windows clients sends encrypted passwords, and Samba needs to be configured to expect and decrypt them. We'll show you how to set up Samba for this task later in the chapter, assuming you haven't already tackled this problem in <a href="ch02_01.html"><b>Chapter 2, <CITE CLASS="chapter">Installing Samba on a Unix System</cite></b></a>.</p><P CLASS="para">Let's start with a single user. The easiest way to set up a client user is to create a Unix account (and home directory) for that individual on the server, and notify Samba of the user's existence. You can do the latter by creating a disk share that maps to the user's home directory in the Samba configuration file, and restricting access to that user with the <CODE CLASS="literal"> -valid</code> <CODE CLASS="literal"> -users</code> option.

However, there are two other options that have to be set correctly in order for this to work.</p><P CLASS="para"> -The easier of the two is <CODE CLASS="literal"> -passwd</code> <CODE CLASS="literal"> -program</code>.

For example, let's assume that you want to use a script called <CODE CLASS="literal"> -changepass</code> to change a user's password.

If you needed a machine's address, you simply broadcast its name across the network and, in theory, the machine itself would reply. This approach is still possible: anyone looking for a machine named <CODE CLASS="literal"> -fred</code> can still broadcast a query and find out if it exists and what its IP address is. (We use this capability to troubleshoot Samba name services with the <CODE CLASS="literal"> -nmblookup</code> command in <a href="ch09_01.html"><b>Chapter 9, <CITE CLASS="chapter">Troubleshooting Samba</cite></b></a>.)</p><P CLASS="para"> -As you saw in the first chapter, however, broadcasting - whether it be browsing or name registration and resolution - does not pass easily across multiple subnets. In addition, many broadcasts tend to bog down networks. To solve this problem, Microsoft now provides the Windows Internet Naming Service (WINS), a cross-subnet NBNS, which Samba supports. With it, an administrator can designate a single machine to act as a WINS server, and can then provide each client that requires name resolution the address of the WINS server. Consequently, name registration and resolution requests can be directed to a single machine from any point on the network, instead of broadcast.</p><P CLASS="para"> -WINS and broadcasting are not the only means of name resolution, however.

Really. Nobody can see you, and we won't tell. In fact, Samba ships with a large set of documentation files, and it is well worth the effort to at least browse through them, either in the distribution directory on your computer under <I CLASS="filename"> -/docs</i>, or online at the Samba web site: <a href="http://samba.anu.edu.au/samba/"><I CLASS="filename">http://samba.anu.edu.au/samba/</i></a>.

In the past few years, though, this vast pool of knowledge has developed something that has made it into an invaluable resource: a memory. Archival and search sites such as DejaNews (<I CLASS="filename"><a href="http://www.dejanews.com">http://www.dejanews.com</i></a>) have made sifting through years of valuable solutions on a topic as simple as a few mouse clicks. </p><P CLASS="para"> -The primary newsgroup for Samba is <EM CLASS="emphasis"> -comp.protocols.smb</em>. This should always be your first stop when there's a problem. More often than not, spending five minutes researching an error here will save hours of frustration while trying to debug something yourself.</p><P CLASS="para"> -When searching a newsgroup, try to be as specific as possible, but not too wordy. Searching on actual error messages is best. If you don't find an answer immediately in the newsgroup, resist the temptation to post a request for help until you've done a bit more work on the problem. You may find that the answer is in a FAQ or one of the many documentation files that ships with Samba, or a solution might become evident when you run one of Samba's diagnostic tools. If nothing works, post a request in <EM CLASS="emphasis"> -comp.protocols.smb</em>, and be as specific as possible about what you have tried and what you are seeing. Include any error messages that appear. It may be several days before you receive help, so be patient and keep trying things while you wait.</p><P CLASS="para"> -Once you post a request for help, keep poking at the problem yourself. Most of us have had the experience of posting a Usenet article containing hundreds of lines of intricate detail, only to solve the problem an hour later after the article has blazed its way across several continents. The rule of thumb goes something like this: the more folks who have read your request, the simpler the solution. Usually this means that once everyone in the Unix community has seen your article, the solution will be something simple like, "Plug the computer into the wall socket."</p></div><DIV CLASS="sect2"> -<H3 CLASS="sect2"> -<A CLASS="title" NAME="ch09-pgfId-951527"> -9.3.3 Samba Mailing Lists</a></h3><P CLASS="para">The following are mailing lists for support with Samba.
