124 <para>Before you compile the program, ensure that the
125 <systemitem class="username">nobody</systemitem> user and
126 <systemitem class="groupname">nogroup</systemitem> group have been
127 created. You can add them by running the following commands as the
128 <systemitem class="username">root</systemitem> user:</para>
129
130<screen role="root"><userinput>groupadd -g 99 nogroup &amp;&amp;

134 <note>
135 <para>The classic uid and gid values are 65534 which is also -2 when
136 interpreted as a signed 16-bit number. These values impact other files
137 on some filesystems that do not have support for sparse files. The
138 <systemitem class="username">nobody</systemitem> and <systemitem
139 class="groupname">nogroup</systemitem> values are relatively arbitrary.
140 The impact on a server is nil if the <filename>exports</filename> file
141 is configured correctly. If it is misconfigured, an
142 <command>ls -l</command> or <command>ps</command> listing will show a
143 uid or gid number of 65534 instead of a name. The client uses <systemitem
144 class="username">nobody</systemitem> only as the user running
145 <command>rpc.statd</command>.</para>
