+# for connecting to multi-client server.     #
+#                                            #
+# This configuration can be used by multiple #
+# clients, however each client should have   #
+# its own cert and key files.                #
+#                                            #
+# On Windows, you might want to rename this  #
+# file so it has a .ovpn extension           #

+===== 起動 =====
+設定変更を systemd に通知するため、"systemctl daemon-reload" を行ってから起動します。
+<code>
+root@plum:~# systemctl daemon-reload
+root@plum:~# systemctl start openvpn
+</code>
+\\
+設定がきちんとできていれば、tun0 I/F が up して通信ができるようになります。
+<code>
