In addition, the <code>NEWS</code> file contains a list of the bugs that have fixed, and comments about any changes the bugfix required. <b>Please</b> read these files carefully before starting your upgrade. <p> One safe way to test the upgrade is to compile the new <code>proftpd</code>, and test it out on your existing configuration file before actually installing the new version into the "live" location: <pre> tar zxvf proftpd-<i>version</i>.tar.gz cd proftpd-<i>version</i>/ ./configure .. make ./proftpd -t -d10 -c /path/to/proftpd.conf </pre> The "<code>./proftpd</code>" means to use the new <code>proftpd</code> binary compiled by <code>make</code>, but not yet installed. If the new binary reports errors, make a copy of your existing <code>proftpd.conf</code> file, keeping the old one as a backup: <pre> cp /path/to/proftpd.conf /path/to/proftpd.conf.new </pre> Make any needed changes to the <code>proftpd.conf.new</code> file, until the new <code>proftpd</code> binary reports a successful syntax check: <pre> ./proftpd -t -d10 -c /path/to/proftpd.conf.new </pre> <p> Once everything is configured the way you like, install the new binary and configuration file: <pre> make install cp /path/to/proftpd.conf /path/to/proftpd.conf.old mv /path/to/proftpd.conf.new /path/to/proftpd.conf </pre> Now do a stop/start on <code>proftpd</code>, and the new version of ProFTPD will be running. <p> <hr> <i>$Date: 2010/01/21 17:37:16 $</i><br> </body> </html>
