Hi, I'd like to know where to find smb. Pitfrr Neophyte Sage. Joined Feb 10, Messages When I had some issues with SMB and tried to debug it I found a smb4. I just checked, it can also be found in TrueNAS at the same location. Thanks, i found it where you said it was, but now, my question is about its content. Click to expand Fredda Neophyte Sage. Joined Jul 9, Messages Editing the smb. If you need some options which are not directly configurable via the GUI there is always the Auxiliary Paramters field.
Multiple backends can be specified at the same time, with different log levels for each backend. The parameter is a list of backends, where each backend is specified as backend[:option][ loglevel]. The 'option' parameter can be used to pass backend-specific options. The log level for a backend is optional, if it is not set for a backend, all messages are sent to this backend. The parameter log level determines overall log levels, while the log levels specified here define what is sent to the individual backends.
When logging is set, it overrides the syslog and syslog only parameters. Some backends are only available when Samba has been compiled with the additional libraries. This parameter has been extended since the 2. This is to give greater flexibility in the configuration of the system. Support is comprehensive for all authentication and authorisation of user accounts in the Samba Active Directory Domain Controller, as well as the implicit authentication in password changes.
Logging the transaction details allows the identification of password and sam. This is only useful for development purposes. Note that this option is only useful if Samba is set up as a logon server. This option takes the standard substitutions, allowing you to have separate logon scripts for each user or machine.
This parameter can be used with Win9X workstations to ensure that roaming profiles are stored in a subdirectory of the user's home directory.
Note that in prior versions of Samba, the logon path was returned rather than logon home. The current implementation is correct, and can be used for profiles if you use the above trick. This option is only useful if Samba is set up as a logon server. Contrary to previous versions of these manual pages, it has nothing to do with Win 9X roaming profiles. To find out how to handle roaming profiles for Win 9X system, see the logon home parameter. It also specifies the directory from which the "Application Data", desktop, start menu, network neighborhood, programs and other folders, and their contents, are loaded and displayed on your Windows NT client.
The share and the path must be readable by the user for the preferences and directories to be loaded onto the Windows NT client. The share must be writeable when the user logs in for the first time, in order that the Windows NT client can create the NTuser. Thereafter, the directories and any of the contents can, if required, be made read-only. It is not advisable that the NTuser. Windows clients can sometimes maintain a connection to the [homes] share, even though there is no user logged in.
Therefore, it is vital that the logon path does not include a reference to the homes share i. Warning Do not quote the value. Where the tdbsam or ldapsam passdb backend is used, at the time the user account is created the value configured for this parameter is written to the passdb backend and that value will over-ride the parameter value present in the smb.
Any error present in the passdb backend account record must be editted using the appropriate tool pdbedit on the command-line, or any other locally provided system tool.
Note that this option is only useful if Samba is set up as a domain controller. Disable the use of roaming profiles by setting the value of this parameter to the empty string. Take note that even if the default setting in the smb.
Disabling of all roaming profile use requires that the user account settings must also be blank. Using a DOS-style editor to create the file is recommended. The script must be a relative path to the [netlogon] service. BAT The contents of the batch file are entirely your choice.
Note that it is particularly important not to allow write access to the [netlogon] share, or to grant users write permission on the batch files in a secure environment, as this would allow the batch files to be arbitrarily modified and security to be breached.
This option is only useful if Samba is set up as a logon server in a classic domain controller role. If this happens, there is a risk of data corruption because the Windows client did not complete all write operations that the Windows application requested. Setting this option to "yes" makes smbd log with a level 0 message a list of all files that have been opened for writing when the network connection died.
Those are the files that are potentially corrupted. It is meant as an aid for the administrator to give him a list of files to do consistency checks on. This command should be a program or script which takes a printer name and job number to pause the print job. One way of implementing this is by using job priorities, where jobs having a too low priority won't be sent to the printer.
Note that it is good practice to include the absolute path in the lppause command as the PATH may not be available to the server. A separate cache is kept for each variation of the lpq command used by the system, so if you use different lpq commands for different users then they won't share cache information. The default is 30 seconds, meaning that the cached results of a previous identical lpq command will be used if the cached data is less than 30 seconds old.
A large value may be advisable if your lpq command is very slow. A value of 0 will disable caching completely. This command should be a program or script which takes a printer name as its only parameter and outputs printer status information.
This covers most UNIX systems. Some clients notably Windows for Workgroups may not correctly send the connection number for the printer they are requesting status information about. To get around this, the server reports on the first printer service connected to by the client.
This only happens if the connection number sent is invalid. Otherwise it is placed at the end of the command. When compiled with the CUPS libraries, no lpq command is needed because smbd will make a library call to obtain the print queue listing. This command should be a program or script which takes a printer name and job number to resume the print job. See also the lppause command parameter. Note that it is good practice to include the absolute path in the lpresume command as the PATH may not be available to the server.
See also the printing parameter. This command should be a program or script which takes a printer name and job number, and deletes the print job. Note that it is good practice to include the absolute path in the lprm command as the PATH may not be available to the server. When enabled, this matches the behaviour of Microsoft's Windows, due to their internal implementation choices. If it is disabled the default , the AD DC can offer improved performance, as the netlogon server is decoupled and can run as multiple processes.
This parameter specifies how often this password will be changed, in seconds. The default is one week expressed in seconds , the same as a Windows NT Domain member server. Warning If two clients use the same magic script in the same directory the output file content is undefined. Scripts executed in this way will be deleted upon completion assuming that the user has the appropriate level of privilege and the file permissions allow the deletion.
If the script generates output, output will be sent to the file specified by the magic output parameter see above. Magic scripts must be executable as is on the host, which for some hosts and some shells will require filtering at the DOS end. See the section on name mangling for details on how to control the mangling process.
Possible option settings are o yes - enables name mangling for all not DOS 8. This is the most sensible setting for modern clients that don't use the shortname anymore. If mangling is used then the mangling method is as follows: o The first up to five alphanumeric characters before the rightmost dot of the filename are preserved, forced to upper case, and appear as the first up to five characters of the mangled name. The final extension is included in the hash calculation only if it contains any upper case characters or is longer than three characters.
The two-digit hash value consists of upper case alphanumeric characters. This algorithm can cause name collisions only if files in a directory share the same first five alphanumeric characters. Mangled names do not change between sessions. A larger value will give a weaker hash and therefore more name collisions. The minimum value is 1 and the maximum value is 6. Use this option to set it to whatever you prefer. This is effective only when mangling method is hash. Can take two different values, "hash" and "hash2".
Many Win32 applications store the mangled names and so changing to algorithms must not be done lightly as these applications may break unless reinstalled.
The DOS archive bit is set when a file has been modified since its last backup. This can be quite annoying for shared source code, documents, etc Note that this parameter will be ignored if the store dos attributes parameter is set, as the DOS archive attribute will then be stored inside a UNIX extended attribute. Note that this requires the create mask parameter to be set such that owner execute bit is not masked out i. See the parameter create mask for details. Note that this parameter will be ignored if the store dos attributes parameter is set, as the DOS hidden attribute will then be stored inside a UNIX extended attribute.
Note that this requires the create mask to be set such that the world execute bit is not masked out i. This parameter can take three different values, which tell smbd 8 how to display the read only attribute on files, where either store dos attributes is set to No , or no extended attribute is present. If store dos attributes is set to yes then this parameter is ignored.
The three settings are : o Yes - The read only DOS attribute is mapped to the inverse of the user or owner write bit in the unix permission mode set. If the owner write bit is not set, the read only attribute is reported as being set on the file. If the read only DOS attribute is set, Samba sets the owner, group and others write bits to zero.
Write bits set in an ACL are ignored by Samba. If the read only DOS attribute is unset, Samba simply sets the write bit of the owner to one. If the connecting user does not have permission to modify the file, the read only attribute is reported as being set on the file. This may be useful for exporting mounted CDs. Note that this parameter will be ignored if the store dos attributes parameter is set, as the DOS 'read-only' attribute will then be stored inside a UNIX extended attribute.
The default has changed to no in Samba release 4. In addition the default setting of store dos attributes has been changed to Yes in Samba release 4.
Note that this parameter will be ignored if the store dos attributes parameter is set, as the DOS system attribute will then be stored inside a UNIX extended attribute. Note that this requires the create mask to be set such that the group execute bit is not masked out i. The four settings are : o Never - Means user login requests with an invalid password are rejected. This is the default.
Note that this can cause problems as it means that any user incorrectly typing their password will be silently logged on as "guest" - and will not know the reason they cannot access files they think they should - there will have been no message given to them that they got their password wrong. Helpdesk services will hate you if you set the map to guest parameter this way This was the default behavior of Samba 2.
Note that this parameter is needed to set up "Guest" share services. This is because in these modes the name of the resource being requested is not sent to the server until after the server has successfully authenticated the client so the server cannot make authentication decisions at the correct time connection to the share for "Guest" shares.
If max connections is greater than 0 then connections will be refused if this number of connections to the service are already open. A value of zero mean an unlimited number of connections may be made. Record lock files are used to implement this feature. The lock files will be stored in the directory specified by the lock directory option. If you set this option to then all shares will appear to be not larger than MB in size.
Note that this option does not limit the amount of data you can put on the disk. In the above case you could still store much more than MB on the disk, but if a client ever asks for the amount of free disk space or the total disk size then the result will be bounded by the amount specified in max disk size. This option is primarily useful to work around bugs in some pieces of software that can't handle very large disks, particularly disks over 1GB in size.
A max disk size of 0 means no limit. Samba periodically checks the size and if it is exceeded it will rename the file, adding a. A size of 0 means no limit. This parameter can be set very high as Samba uses only one bit per unopened file.
Setting this parameter lower than will cause Samba to complain and set this value back to the minimum of , as Windows 7 depends on this number of open file handles being available. The limit of the number of open files is usually set by the UNIX per-process file descriptor limit rather than this parameter so you should never need to touch this parameter.
If this number is exceeded, smbd 8 will remote "Out of Space" to the client. If this number is exceeded, the excess jobs will not be shown.
A value of zero means there is no limit on the number of print jobs reported. Remember that under normal operating conditions, each user will have an smbd 8 associated with him or her to handle connections to all shares from a given host. For a Samba ADDC running the standard process model this option limits the number of processes forked to handle requests. Currently new processes are only forked for ldap and netlogon requests. It represents the number of kilobyte units the stat cache can use.
A value of zero, meaning unlimited, is not advisable due to increased memory usage. You should not need to change this parameter.
You should never need to change this parameter. The default is 3 days. The default is 6 days seconds. The default is , which matches the behavior of Windows A value below is likely to cause problems.
You should never need to change this parameter from its default value. A setting of mdns will defer the hostname configuration to the MDNS library that is used. This would normally be a command that would deliver the message somehow. How this is to be done is up to your imagination. If it doesn't return immediately then your PCs may freeze when sending messages they should recover after 30 seconds, hopefully.
All messages are delivered as the global guest user. Apart from the standard substitutions, some additional ones apply. You could make this command send mail, or whatever else takes your fancy. Please let us know of any really interesting ideas you have.
Unfortunately WfWg totally ignores the error code and carries on regardless, saying that the message was delivered. It is specified in kilobytes. The default is 0, which means a user can always spool a print job.
This allows zero-copy writes directly from network socket buffers into the filesystem buffer cache, if available. It may improve performance but user testing is recommended. The maximum value is k. Values greater than k will be silently set to k.
The default is zero, which disables this option. The default is 6 hours seconds. If the KDC is not installed in the default location and wasn't correctly detected during build then you should modify this variable and point it to the correct binary.
When clients attempt to connect to this share, they are redirected to one or multiple, comma separated proxied shares using the SMB-Dfs protocol. Only Dfs roots can act as proxy shares.
Take a look at the msdfs root and host msdfs options to find out how to set up a Dfs root share. This parameter allows disabling Samba to register itself.
If the timeout is set to 0. Its main purpose to is to control how netbios name resolution is performed. The option takes a space separated string of name resolution options. The options are: "lmhosts", "host", "wins" and "bcast". They cause names to be resolved as follows: o lmhosts : Lookup an IP address in the Samba lmhosts file.
If the line in lmhosts has no name type attached to the NetBIOS name see the manpage for lmhosts for details then any name type matches for lookup. Note that this method is used only if the NetBIOS name type being queried is the 0x20 server name type or 0x1c domain controllers. If no WINS server has been specified this method will be ignored. This is the least reliable of the name resolution methods as it depends on the target host being on a locally connected subnet.
The example below will cause the local lmhosts file to be examined first, followed by a broadcast attempt, followed by a normal system hostname lookup. Setting this option should never be necessary on usual Samba servers running only one nmbd. This parameter is deprecated. As many client only use the first address in the list by default, all clients will use the same server the PDC.
Windows servers have an option to disable this behavior since Windows Service Pack 2. Windows servers have an option to change this behavior and randomize the returned addresses. If there are addresses which are in the same subnet as the client address, the first returned address is randomly chosen out them. Otherwise the first returned address is randomly chosen out of all addresses.
This allows one machine to appear in browse lists under multiple names. If a machine is acting as a browse server or logon server none of these names will be advertised as either browse server or logon servers, only the primary name of the machine will be advertised with these capabilities.
By default it is the same as the first component of the host's DNS name. If a machine is a browse server or logon server this name or the first component of the hosts DNS name will be the name that these services are advertised under. There is a bug in Samba that breaks operation of browsing and access to shares if the netbios name is set to the literal name PIPE. This should not be set unless every machine on your LAN also sets this value.
Typically you should not need set this. It can be useful for upgrades from NT4 to AD domains. For UNIX systems that use an automounter, the user's home directory will often be mounted on a workstation on demand from a remote server. When the Samba logon server is not the actual home directory server, but is mounting the home directories via NFS then two network hops would be required to access the users home directory if the logon server told the client to use itself as the SMB server for home directories one over SMB and one over NFS.
This can be very slow. This option allows Samba to return the home share as being on a different server to the logon server and as long as a Samba daemon is running on the home directory server, it will be mounted on the Samba client directly from the directory server.
When Samba is returning the home share to the client, it will consult the NIS map specified in homedir map and return the server listed there. Note that for this option to work there must be a working NIS system and the Samba server with this option must also be a logon server. This is needed to make nmbd work correctly in combination with the socket address option. You should not need to unset this option. This parameter was formally a global parameter in releases prior to 2.
Note that these settings apply only to local users, authentication will still be forwarded to and NTLM authentication accepted against any domain we are joined to, and any trusted domain, even if disabled or if NTLMv2-only is enforced here. By default with ntlm auth set to ntlmv2-only only NTLMv2 logins will be permitted. All modern clients support NTLMv2 by default, but some older clients will require special configuration to use it.
This is the required setting for to enable the lanman auth parameter. The default changed from yes to no with Samba 4. The default changed again to ntlmv2-only with Samba 4. This is a developer debugging option and can be left alone. If a non-default path is specified here, then it is also necessary to make NTP aware of the new path using the ntpsigndsocket directive in ntp.
This is a developer debugging option and should be left alone. If this option is set to no then Samba offers exactly the same DOS error codes that versions prior to Samba 2. You should not need to ever disable this parameter. Mainly useful for testing.
It is not used with the default s3fs file server. See also smbpasswd 5. The default behavior is to use PAM for clear text authentication only and to ignore any account or session management. This allows the user to re-cache the new password on multiple clients without disrupting a network reconnection in the meantime.
If Samba responds to a client too quickly when that client issues an SMB that can cause an oplock break request, then the network client can fail and not respond to the break request. This tuning parameter which is set in milliseconds is the amount of time Samba will wait before sending an oplock break request to such broken clients.
The oplock code can dramatically approx. It allows the clients to aggressively cache files locally and you may want to disable this option for unreliable network environments it is turned on by default in Windows NT Servers.
Oplocks may be selectively turned off on certain files with a share. See the veto oplock files parameter. On some systems oplocks are recognized by the underlying operating system.
See the kernel oplocks parameter for details. HP LaserJet 5L. The value of this parameter determines whether nmbd 8 has a chance of becoming a local master browser for the workgroup in the local broadcast area. Note: By default, Samba will win a local master browsing election over all Microsoft operating systems except a Windows NT 4.
This means that a misconfigured Samba host can effectively isolate a subnet for browsing purposes. This parameter is largely auto-configured in the Samba-3 release series and it is seldom necessary to manually override the default setting. Note: The maximum value for this parameter is If you use higher values, counting will start at 0! If enabled, then PAM will be used for password changes when requested by an SMB client instead of the program listed in passwd program.
It should be possible to enable this without changing your passwd chat parameter for most setups. This is usually used to draw attention to the fact that a problem occurred. This allows you to swap between different storage mechanisms without recompile.
The parameter value is divided into two parts, the backend's name, and a 'location' string that has meaning only to that particular backed. These are separated by a : character. Available backends can include: o smbpasswd - The old plaintext passdb backend. Some Samba features will not work if this passdb backend is used.
Takes a path to the smbpasswd file as an optional argument. Takes a path to the TDB as an optional argument defaults to passdb. Multiple servers may also be specified in double-quotes. Whether multiple servers are supported or not and the exact syntax depends on the LDAP library you use. The string describes a sequence of response-receive pairs that smbd 8 uses to determine what to send to the passwd program and what to expect back. If the expected output is not received then the password is not changed.
This chat sequence is often quite site specific, depending on what local methods are used for password control such as NIS etc. Note that this parameter only is used if the unix password sync parameter is set to yes. This means that root must be able to reset the user's password without knowing the text of the previous password.
Double quotes can be used to collect strings with spaces in them into a single string. If the send string in any part of the chat sequence is a full stop ". Similarly, if the expect string is a full stop then no string is expected.
If the pam password change parameter is set to yes , the chat pairs may be matched in any order, and success is determined by the PAM result, not any particular output.

Docs » Note Shares are created to provide and control access to an area of storage. Note It is generally a mistake to share a pool or dataset with more than one share type or access method. Note Table Note When a guest share is created along with a share that requires authentication, AFP only maps users who log in as guest to the guest share. A better option is to do this: Specify the built-in nobody account to be used for NFS access.
In the Change Permissions screen of the pool or dataset that is being shared, change the owner and group to nobody and set the permissions according to the desired requirements. Note If this command fails on a Linux system, make sure that the nfs-utils package is installed. Warning At this time, only the webdav user is supported. Warning SMB1 is disabled by default for security.
Note Be careful when using multiple SMB shares, some with and some without fruit. Note If a dataset for the share has not been created, refer to Adding Datasets to find out more about dataset creation.
Refer to Users for more information about creating a user. After the user has been created, use the drop-down to select the user account. Group: Use the drop-down to select the desired group name.
Refer to Groups for more information about creating a group. Click SAVE. Do you want to continue this operation? Is it OK to continue disconnecting and force them closed? If no previous versions of files to restore are visible, use Windows Update to ensure the system is fully up-to-date. Shadow copy support only works for ZFS pools or datasets.
This means that the SMB share must be configured on a pool or dataset, not on a directory. Datasets are filesystems and shadow copies cannot traverse filesystems. To see the shadow copies in the child datasets, create separate shares for them. Shadow copies will not work with a manual snapshot. Creating a periodic snapshot task for the pool or dataset being shared by SMB or a recursive task for a parent dataset is recommended.
The periodic snapshot task should be created and at least one snapshot should exist before creating the SMB share. Appropriate permissions must be configured on the pool or dataset being shared by SMB. Users cannot delete shadow copies on the Windows system due to the way Samba works. The only way to disable shadow copies completely is to remove the periodic snapshot task and delete all snapshots associated with the SMB share.
There are two options for snapshot tasks. When creating the schedule for the periodic snapshot tasks, keep in mind how often the users need to access modified files and during which days and time of day they are likely to make changes. Use the Periodic Snapshot Task drop-down menu to select the periodic snapshot task to use for that share. Repeat for each share being configured as a shadow copy. Verify that the SMB service is running in Services.
Before configuring the iSCSI service, be familiar with this iSCSI terminology: CHAP: an authentication method which uses a shared secret and three-way authentication to determine if a system is authorized to access the storage device and to periodically confirm that the session has not been hijacked by another system.
Extent: the storage unit to be shared. It can either be a file or a device. Create at least one portal. Determine which hosts are allowed to connect using iSCSI and create an initiator.
If using authentication, create an authorized access. Create a target. Create either a device or a file extent to be used as storage. Associate a target with an extent. The rest of this section describes these steps in more detail. Note This screen sets login authentication. File extents provide virtual storage access to an individual file. Tip For typical use as storage for virtual machines where the virtualization software is the iSCSI initiator, device extents with zvols provide the best performance and most features.
Note The web interface does not allow reducing the size of the zvol, as doing so could result in loss of data. User: Use the drop-down to select the desired user account. See users for more information. Group: Select the desired group name. See groups for more information.
Browse to the dataset created for the share. When creating a Time Machine share, set the Time Machine option. Fill out the other required fields. To use this client, you will need to install the following on the Windows system: 7zip to extract the Nekodrive download files NFSClient and NFSLibrary from the Nekodrive download page; once downloaded, extract these files using 7zip.
NET Framework 4. This section will demonstrate some common configuration scenarios: If you would like an overview of the configurable parameters, see Creating CIFS Shares. If you would like an example of how to configure access that does not require authentication, see Configuring Anonymous Access.
If you would like each user to authenticate before accessing the share, see Configuring Local User Access. Only change the type of permissions to Windows if the share is only accessed by Windows systems. After a second or so, it will change to a blue ON, indicating that the service has been enabled.
Test the share. Once the group is created, click its Members button and add the user accounts that you created in step 1.
Note since the share is group writable, any authenticated user can change the data in the share. If you are unable to see any previous versions of files to restore, use Windows Update to make sure that the system is fully up-to-date. This means that the CIFS share must be configured on a volume or dataset, not on a directory. The only way to disable shadow copies completely is to remove the periodic snapshot task and delete all snapshots associated with the CIFS share.
Alternatively, you can create one periodic snapshot task for the entire data volume. When creating your snapshots, keep in mind how often your users need to access modified files and during which days and time of day they are likely to make changes.
Two shares should appear, named user1 and user2. Due to the permissions on the datasets, user1 should receive an error if they click on the user2 share. Due to the permissions on the datasets, user1 should be able to create, add, and delete files and folders from the user1 share. Table Of Contents 9. Sharing Configuration 9. Apple AFP Shares 9.
