When run as a normal -user it allows the user to change the password used for their SMB -sessions on any machines that store SMB passwords. -<p>By default (when run with no arguments) it will attempt to change the -current users SMB password on the local machine. This is similar to -the way the <strong>passwd (1)</strong> program works. <strong>smbpasswd</strong> differs from how -the <strong>passwd</strong> program works however in that it is not <em>setuid root</em> -but works in a client-server mode and communicates with a locally -running <a href="smbd.8.html"><strong>smbd</strong></a>. As a consequence in order for this -to succeed the <a href="smbd.8.html"><strong>smbd</strong></a> daemon must be running on -the local machine. On a UNIX machine the encrypted SMB passwords are -usually stored in the <a href="smbpasswd.5.html"><strong>smbpasswd (5)</strong></a> file. -<p>When run by an ordinary user with no options. <strong>smbpasswd</strong> will -prompt them for their old smb password and then ask them for their new -password twice, to ensure that the new password was typed -correctly. No passwords will be echoed on the screen whilst being -typed. If you have a blank smb password (specified by the string "NO -PASSWORD" in the <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file) then just -press the <Enter> key when asked for your old password. -<p><strong>smbpasswd</strong> can also be used by a normal user to change their SMB -password on remote machines, such as Windows NT Primary Domain -Controllers. See the <a href="smbpasswd.8.html#minusr">(<strong>-r</strong>)</a> and -<a href="smbpasswd.8.html#minusU"><strong>-U</strong></a> options below. -<p>When run by root, <strong>smbpasswd</strong> allows new users to be added and -deleted in the <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file, as well as -allows changes to the attributes of the user in this file to be made. When -run by root, <strong>smbpasswd</strong> accesses the local -<a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file directly, thus enabling -changes to be made even if <a href="smbd.8.html"><strong>smbd</strong></a> is not running. -<p><a name="OPTIONS"></a> -<h2>OPTIONS</h2> - -<p><dl> -<p><a name="minusa"></a> -<p></p><dt><strong><strong>-a</strong></strong><dd> This option specifies that the username following should -be added to the local <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file, with -the new password typed (type <Enter> for the old password). This -option is ignored if the username following already exists in the -<a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file and it is treated like a -regular change password command. Note that the user to be added -<strong>must</strong> already exist in the system password file (usually /etc/passwd) -else the request to add the user will fail. -<p>This option is only available when running <strong>smbpasswd</strong> as -root. -<p><a name="minusx"></a> -<p></p><dt><strong><strong>-x</strong></strong><dd> This option specifies that the username following should -be deleted from the local <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file. -<p>This option is only available when running <strong>smbpasswd</strong> as -root. -<p><a name="minusd"></a> -<p></p><dt><strong><strong>-d</strong></strong><dd> This option specifies that the username following should be -<em>disabled</em> in the local <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file. -This is done by writing a <em>'D'</em> flag into the account control space -in the <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file.

Without this parameter <strong>smbpasswd</strong> defaults to the local -host. The <em>"remote machine name"</em> is the NetBIOS name of the -SMB/CIFS server to contact to attempt the password change. This name -is resolved into an IP address using the standard name resolution -mechanism in all programs of the <a href="samba.7.html"><strong>Samba</strong></a> -suite. See the <a href="smbpasswd.8.html#minusR"><strong>-R name resolve order</strong></a> parameter for details on changing this resolving -mechanism. -<p>The username whose password is changed is that of the current UNIX -logged on user. See the <a href="smbpasswd.8.html#minusU"><strong>-U username</strong></a> -parameter for details on changing the password for a different -username. -<p>Note that if changing a Windows NT Domain password the remote machine -specified must be the Primary Domain Controller for the domain (Backup -Domain Controllers only have a read-only copy of the user account -database and will not allow the password change). -<p><em>Note</em> that Windows 95/98 do not have a real password database -so it is not possible to change passwords specifying a Win95/98 -machine as remote machine target. -<p><a name="minusR"></a> -<p></p><dt><strong><strong>-R name resolve order</strong></strong><dd> This option allows the user of -smbclient to determine what name resolution services to use when -looking up the NetBIOS name of the host being connected to. -<p>The options are :<a href="smbpasswd.8.html#lmhosts">"lmhosts"</a>, <a href="smbpasswd.8.html#host">"host"</a>, -<a href="smbpasswd.8.html#wins">"wins"</a> and <a href="smbpasswd.8.html#bcast">"bcast"</a>.

This is the least reliable of the name resolution -methods as it depends on the target host being on a locally connected -subnet. -<p></dl> -<p>If this parameter is not set then the name resolve order defined -in the <a href="smb.conf.5.html"><strong>smb.conf</strong></a> file parameter -<a href="smb.conf.5.html#nameresolveorder"><strong>name resolve order</strong></a> -will be used. -<p>The default order is lmhosts, host, wins, bcast and without this -parameter or any entry in the <a href="smb.conf.5.html"><strong>smb.conf</strong></a> -file the name resolution methods will be attempted in this order. -<p><a name="minusm"></a> -<p></p><dt><strong><strong>-m</strong></strong><dd> This option tells <strong>smbpasswd</strong> that the account being -changed is a <em>MACHINE</em> account. Currently this is used when Samba is -being used as an NT Primary Domain Controller. PDC support is not a -supported feature in Samba2.0 but will become supported in a later -release. If you wish to know more about using Samba as an NT PDC then -please subscribe to the mailing list -<a href="mailto:samba-ntdom@samba.org"><em>samba-ntdom@samba.org</em></a>. -<p>This option is only available when running <strong>smbpasswd</strong> as root. -<p><a name="minusj"></a> -<p></p><dt><strong><strong>-j DOMAIN</strong></strong><dd> This option is used to add a Samba server into a -Windows NT Domain, as a Domain member capable of authenticating user -accounts to any Domain Controller in the same way as a Windows NT -Server. See the <a href="smb.conf.5.html#security"><strong>security=domain</strong></a> -option in the <a href="smb.conf.5.html"><strong>smb.conf (5)</strong></a> man page. -<p>In order to be used in this way, the Administrator for the Windows -NT Domain must have used the program <em>"Server Manager for Domains"</em> -to add the <a href="smb.conf.5.html#netbiosname">primary NetBIOS name</a> of -the Samba server as a member of the Domain. -<p>After this has been done, to join the Domain invoke <strong>smbpasswd</strong> with -this parameter. <strong>smbpasswd</strong> will then look up the Primary Domain -Controller for the Domain (found in the -<a href="smb.conf.5.html"><strong>smb.conf</strong></a> file in the parameter -<a href="smb.conf.5.html#passwordserver"><strong>password server</strong></a> and change -the machine account password used to create the secure Domain -communication. This password is then stored by <strong>smbpasswd</strong> in a -file, read only by root, called <code><Domain>.<Machine>.mac</code> where -<code><Domain></code> is the name of the Domain we are joining and <code><Machine></code> -is the primary NetBIOS name of the machine we are running on. -<p>Once this operation has been performed the -<a href="smb.conf.5.html"><strong>smb.conf</strong></a> file may be updated to set the -<a href="smb.conf.5.html#security"><strong>security=domain</strong></a> option and all -future logins to the Samba server will be authenticated to the Windows -NT PDC. -<p>Note that even though the authentication is being done to the PDC all -users accessing the Samba server must still have a valid UNIX account -on that machine. -<p>This option is only available when running <strong>smbpasswd</strong> as root. -<p><a name="minusU"></a> -<p></p><dt><strong><strong>-U username</strong></strong><dd> This option may only be used in -conjunction with the <a href="smbpasswd.8.html#minusr"><strong>-r</strong></a> -option. When changing a password on a remote machine it allows the -user to specify the user name on that machine whose password will be -changed. It is present to allow users who have different user names on -different systems to change these passwords. -<p><a name="minush"></a> -<p></p><dt><strong><strong>-h</strong></strong><dd> This option prints the help string for <strong>smbpasswd</strong>, -selecting the correct one for running as root or as an ordinary user. -<p><a name="minuss"></a> -<p></p><dt><strong><strong>-s</strong></strong><dd> This option causes <strong>smbpasswd</strong> to be silent (i.e. not -issue prompts) and to read it's old and new passwords from standard -input, rather than from <code>/dev/tty</code> (like the <strong>passwd (1)</strong> program -does). This option is to aid people writing scripts to drive <strong>smbpasswd</strong> -<p><a name="username"></a> -<p></p><dt><strong><strong>username</strong></strong><dd> This specifies the username for all of the <em>root -only</em> options to operate on. Only root can specify this parameter as -only root has the permission needed to modify attributes directly -in the local <a href="smbpasswd.5.html"><strong>smbpasswd</strong></a> file. -<p><a name="NOTES"></a> -<h2>NOTES</h2> - -<p>Since <strong>smbpasswd</strong> works in client-server mode communicating with a -local <a href="smbd.8.html"><strong>smbd</strong></a> for a non-root user then the <strong>smbd</strong> -daemon must be running for this to work. A common problem is to add a -restriction to the hosts that may access the <strong>smbd</strong> running on the -local machine by specifying a <a href="smb.conf.5.html#allowhosts"><strong>"allow -hosts"</strong></a> or <a href="smb.conf.5.html#denyhosts"><strong>"deny -hosts"</strong></a> entry in the -<a href="smb.conf.5.html"><strong>smb.conf</strong></a> file and neglecting to allow -<em>"localhost"</em> access to the <strong>smbd</strong>. -<p>In addition, the <strong>smbpasswd</strong> command is only useful if <strong>Samba</strong> has -been set up to use encrypted passwords.
