178TFTP requires a bit of configuring to get it to work properly. First, edit
179<path>/etc/conf.d/in.tftpd</path> to set tftpd's options and path correctly:
157<p> 180</p>
158By default TFTP won't be started, to change this edit 181
159<path>/etc/xinetd.d/tftp</path> and replace <c>disable=yes</c> with 182<pre caption="/etc/conf.d/in.tftpd">
160<c>disable=no</c>. Afterwards, start xinetd. 183INTFTPD_PATH="/tftpboot"
184INTFTPD_OPTS="-s ${INTFTPD_PATH}"
185</pre>
186
187<p>
188The -s flag specifies that TFTP is to run in secure chrooted mode
189(recommended). This means that you don't need to include the
190<path>/tftpboot</path> path for example in the DHCP configuration.
191</p>
192
193<p>
194Next, configure xinetd to run TFTP and allow remote connections. By default
195TFTP won't be started by xinetd, so edit <path>/etc/xinetd.d/tftp</path> and
196replace <c>disable=yes</c> with <c>disable=no</c>. If the file is missing just
197go ahead and create <path>/etc/xinetd.d/tftp</path> with the contents below.
198</p>
199
200<pre caption="/etc/xinetd.d/tftp">

211</pre>
212
213<p>
214Now edit <path>/etc/xinetd.conf</path> and comment out the line <c>only_from =
215localhost</c> by prefacing it with a <c>#</c>. Finally, start xinetd.
