 ## 問題のトラブルシューティング
 
-最後の curl は動作しましたか？ netstat コマンドを実行すると、Web サーバーが動作しているポートを確認できます。

 ```bash
-#> sudo netstat -tulpn
+#> sudo ss -tulpn | grep httpd

 次のような行があるはずです。
 
 ```bash
-tcp6       0      0 :::8080                 :::*                    LISTEN      25237/httpd

 ```
 
 これが機能していない場合は、`/etc/httpd/conf/httpd.conf` に `Listen 8080`

 There should be a line like this:
 
 ```bash
-tcp6       0      0 :::8080                 :::*                    LISTEN      25237/httpd

 ```
 
-If it is not working make sure that `/etc/httpd/conf/httpd.conf` has `Listen 8080` in it.  This should have been changed by [Exercise 1.5](../1.5-handlers)
+Pay close attention to the fifth column of the above output. It should be `*:8080`. If it is `*:80` instead or if it is not working, then make sure that the `/etc/httpd/conf/httpd.conf` file has `Listen 8080` in it.  This should have been changed by [Exercise 1.5](../1.5-handlers)
