Samba problems can be difficult to isolate, because you have to deal with both Microsoft Windows and Solaris issues and their integration. For example, Windows and Solaris use completely different authentication systems, particularly with respect to encrypted passwords. Thus, you need to choose whether to enable Windows-style authentication in smb.conf for password encryption or modify the Windows Registry to transmit passwords in the clear. If you suspect a password-related problem, you can disable the use of passwords for authentication by entering the string NOPASSWORDXXXXXXXXXXXXXXXXXXXX . By temporarily removing the password on the Solaris side, you can determine whether an authentication issue is password-related. However, allowing logins to Solaris without passwords is a very bad idea on production systems or those connected to the Internet, so it would be wise to create a special account with /bin/false as the shell, which you must remove after testing. In the first instance, the Samba daemons can be restarted. This can assist you if the daemon has hung, because of a name conflict, timeout, or some other reason. In addition, the daemons must be restarted every time a change is made to the smb.conf file.

If manually configuring Samba by using the smb.conf file is a bit daunting, you can use one of several third-party GUIs to automate the process of creating an smb.conf through a browser. One of the most popular tools is the Samba Web Administration Tool (SWAT), which runs as a service through the Internet super daemon (inetd) on port 901. It can be administered locally, through a browser running on Solaris, or remotely, through a browser running on Microsoft Windows. The current Samba source distribution will build SWAT by default; however, you need to make a number of configuration changes to enable the SWAT service: 1. Map the SWAT service name to the required TCP port (901), by adding the following line to the /etc/services files:

3. For the changes to take effect, restart the inetd service:
# ps -eaf | grep inetd root 200 1 0 Nov 1 01:25 /usr/sbin/inetd -s
4. The PID of inetd is 200, so use the following command to restart the service with the modified inetd.conf file:
kill -1 200
5. After opening a browser, you can then access the SWAT interface by using the URL http://SYDNEY:901/, as shown in Figure 31-3.
NT Authentication
In order to allow users to be authenticated from an NT domain and access Samba shares, insert the following lines into smb.conf:
encrypt passwords = yes security = server password server = "pdc"
In this example, the server name pdc corresponds to the NetBIOS name of the PDC.

Summary
In this chapter, you have examined the basic elements of Samba configuration for Solaris. While Solaris provides NFS as its native distributed file system protocol, SMB makes Solaris more compatible with the Microsoft Windows environment.

Application Development and Debugging
lthough most system administrators are not application developers, in many situations they can make administration tasks much simpler by using a Perl script or small C program that includes system calls. A key challenge of system management involves the automation of as many mundane, repetitive tasks as possible. Although shell or Perl scripting can be useful in this context, as described in 6, sometimes complete programs are required. This chapter examines how to develop, compile, and execute C applications.
Programming Languages
There are many ways to develop software for Solaris, all of which depend on the internal representation of data and executable code. At the most basic level, all data and instructions are encoded as binary data quite literally, sets of 1 s and 0 s that represent data words. For example, a processor with an 8-bit word length means that integers between 0 and 255 can be directly addressed by the CPU, without any kind of intermediate translation. Most Intel CPUs today have a word length of 32 bits, while UltraSPARC processors have a 64-bit word length, making it easier (and faster) to directly process large numbers. This ability is very important in scientific applications, like processing data from human genomes, or in database applications, where transactions of financial data associated with many billions of dollars are performed constantly. In the early days of computing, a new, higher level programming interface was developed, called assembly language. By using assembly language to write programs, instead of directly writing binary code, developers were able to use an interface that was one level of abstraction away from the hardware. They could use English-like statements and identifiers to move and address blocks of memory, for example. This increased productivity and decreased production time. However, anyone who has ever written an assembly language program knows that it is still far from easy. In addition, a different assembly language existed for every processor in existence, meaning that skills developed
