С момента последнего обновления около 4 серверов CentOS показывали проблемы. Все они не могут подключиться к внешнему миру, особенно с веб-сервера. Делая curl или ping из CLI работает нормально. Перезагрузка сервера заставляет все снова работать.
Есть идеи, что здесь может быть не так? Что касается серверов, которые появятся, я, конечно, хотел бы предотвратить перезагрузку ... Я подозреваю, что обновления сетевой прошивки (ниже) что-то испортили.
SELinux должен быть отключен:
[root@server public_html]# sestatus
SELinux status: disabled
Были установлены следующие обновления:
