Most sections define file or printer shares; however, the [global] section is special: It holds options that affect the server as a whole or that set default values used in subsequent share definitions.
The [global] section typically appears first in the file. Lines in smb. Parameter names are caseinsensitive. Some common parameters have synonyms, and a few have antonyms. The Value you specify with a parameter can be a free-form string, a number including specialized numeric values, such as IP addresses , a Boolean value, a variable, or a list.
Boolean values can take either of two truth values: Yes, True, and 1 are synonyms, as are No, False, and 0. Some parameters take lists of several values, such as lists of user names.
In such cases, list elements are separated by commas, as in george, mary to refer to both george and mary. For the most part, the smb. If you need to include white space in a value, enclose it in quotation marks. Options for the different programs are not separated or clearly differentiated, although sometimes the name makes it obvious to which daemon a parameter applies. Learn Linux, Mixed environments : Samba roles Page 4 of 9 ibm. For example, you can tell Samba to shut down a specific share, force a master browser election, reload the configuration file, and so on.
The basic syntax for this command is: smbcontrol [-i] [-s configfile] smbcontrol [destination] [message-type] [parameter] When used with the -i option, smbcontrol enters an interactive mode in which you can pass a series of commands in sequence, saving you from having to type smbcontrol in front of each command. The destination is the server name smbd, nmbd, or winbindd , all to send the message to all the daemons or a process ID number.
The message-type is a command, as summarized in Table 1. The parameter is an optional parameter that some commands may require. Table 1. File system volume and size limits Command message-type close-share debug force-election debuglevel printnotify samsync Meaning Close the share that the parameter specifies.
Set the debug level to the value the parameter specifies. Forces a new master browser election. Displays the current debug level of a daemon.
Sends a message to clients connected to a printer share, forcing a change in the clients' queue status. Synchronize the user database with a domain controller. Official documentation indicates that this function is not currently working; test it before you rely on it. Shuts down the specified daemon. Displays memory use information for the specified daemon.
Notify clients that a new printer driver is available. The command takes a printer share name as a parameter. Forces the server to reload the smb.
The most important of these is the security option, which takes five possible values: Share. To do this, Samba tries the password provided by the client with a variety of user names.
This security mode, which is the default, uses a user name and password for authentication, similar to the way Linux typically works. In most cases on modern systems, though, the password is stored in an encrypted Samba-only password database.
If you want Samba to defer to another server for authentication, use this authentication method. To a client, this method looks just like user-level authentication, but Learn Linux, Mixed environments : Samba roles Page 5 of 9 developerWorks ibm. You can fully join a Windows domain using this method, which looks just like userlevel authentication to clients. Unlike server-level authentication, domain authentication involves a more secure domain-level password exchange.
Fully joining the domain requires running extra commands on the Samba system and possibly on the domain controller, as well. This authentication method works much like domain authentication; however, it requires an Active Directory Domain Services domain controller.
A workgroup differs from a domain mainly in that a domain provides a domain controller, which is a server that provides authentication services to the domain. To use a domain controller, you must use server-, domain-, or ADS-level security.
Server-level security is the easiest to configure but the least secure, whereas ADS-level security is the most difficult to configure but the most secure. To fully join a domain for domain- or ADS-level security, you must set several options in the [global] section of the smb. You must also type the following command on the Samba server that should join the domain: net join member -U adminuser You may also need to configure the domain controller to accept the Samba server into the domain.
Objective Share-level security is largely outmoded; it exists mainly to provide compatibility for very old clients that don't understand user names. It can also be useful for some share types that you might want to make available with minimal security, such as printer shares. Because Linux requires that an account be used for all accesses, Samba tries the provided password against a series of accounts until one matches or they've all failed.
Using it only creates confusion and increases the security riskwith Learn Linux, Mixed environments : Samba roles Page 6 of 9 ibm. Learn Linux, Mixed environments : Samba roles Page 7 of 9 ibm.
