| groups on domain controllers and domain member machines. |
| </pre></div><div class="refsect1"><a name="mkgroup-desc"></a><h2>Description</h2><p>Don't use this command to generate a local /etc/group file, unless you |
| really need one. See the Cygwin User's Guide for more information. |
| </p><p>The <span class="command"><strong>mkgroup</strong></span> program can be used to create a local |
| <code class="filename">/etc/group</code> file. Cygwin doesn't need this file, |
| because it reads group information from the Windows account databases, |
| but you can add an <code class="filename">/etc/group</code> file for instance, if |
| your machine is often disconnected from its domain controller. |
| </p><p>Note that this information is static, in contrast to the information |
| automatically gathered by Cygwin from the Windows account databases. If |
| you change the group information on your system, you'll need to regenerate |
| the group file for it to have the new information.</p><p>By default, the information generated by <span class="command"><strong>mkgroup</strong></span> |
| is equivalent to the information generated by Cygwin itself. The |
| <code class="literal">-d</code> and <code class="literal">-l/-L</code> options allow you to |
| specify where the information comes from, some domain, or the local SAM |
| of a machine. Note that you can only enumerate accounts from trusted |
| domains. Any non-trusted domain will be ignored. Access-restrictions |
| of your current account apply. The <code class="literal">-l/-L</code> when used |
| with a machine name, tries to contact that machine to enumerate local |
| groups of other machines, typically outside of domains. This scenario |
| cannot be covered by Cygwin's account automatism. If you want to use |
| the <code class="literal">-L</code> option, but you don't like the default |
| domain/group separator from <code class="filename">/etc/nsswitch.conf</code>, |
| you can specify another separator using the <code class="literal">-S</code> option, |
| for instance:</p><div class="example"><a name="utils-mkgroup-ex"></a><p class="title"><b>Example 3.9. Setting up group entry for current user with different |
| domain/group separator</b></p><div class="example-contents"><pre class="screen"> |
| <code class="prompt">$</code> <strong class="userinput"><code>mkgroup -L server1 -S= > /etc/group</code></strong> |
| </pre></div></div><br class="example-break"><p>For very simple needs, an entry for the current user's group can be |
| created by using the option <code class="literal">-c</code>.</p><p>The <code class="literal">-o</code> option allows for (unlikely) special cases |
| with multiple machines where the GIDs might match otherwise. The |
| <code class="literal">-g</code> option only prints the information for one group. |
| The <code class="literal">-U</code> option allows you to enumerate the standard |
| UNIX groups on a Samba machine. It's used together with <code class="literal">-l |
| samba-server</code> or <code class="literal">-L samba-server</code>. The normal |
| UNIX groups are usually not enumerated, but they can show up as a group |
| in <span class="command"><strong>ls -l</strong></span> output. </p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="minidumper.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="using-utils.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="mkpasswd.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">minidumper </td><td width="20%" align="center"><a accesskey="h" href="cygwin-ug-net.html">Home</a></td><td width="40%" align="right" valign="top"> mkpasswd</td></tr></table></div></body></html> |
