На машине X я могу подключиться к 127.0.1.1 (у меня есть скрипт php, работающий на машине X, который вызывает phpinfo (), и он работает нормально). IP-адрес X-машины в сети 192.168.1.101. Я перехожу к машине Y и набираю 192.168.1.101 в адресной строке браузера, ожидая увидеть вывод phpinput (). Вместо этого я получаю сообщение об ошибке «истекло время ожидания сервера».
Каким-то образом должен быть способ «подключить» 192.168.1.101 к серверу apache2. Что это? Предположим, что проблем с брандмауэром нет.

Перечислите свой файл httpd.conf и посмотрите, что слушает Apache. Скорее всего, он слушает только localhost.
cat /etc/httpd/conf/httpd.conf | grep -i listen
Если это так, добавьте строку, чтобы позволить ему прослушивать свой IP-адрес или порт.
Другая возможность заключается в том, что ваш брандмауэр блокирует связь с вашим веб-сервером. iptables -L развеял бы (или подтвердил) это представление.
