Subject: [Comm] net.ipv4.ip_forward

Message-ID: <ad95d882-f8c9-fcf2-92bc-0f5cb2aa35cf@gmail.com> (raw)
Доброй ночи.
Как нынче правильно нужно указывать включение net.ipv4.ip_forward и
почему он по умолчанию принудительно устанавливается в "0"?
Вписал как описано в man sysctl в файл /etc/sysctl.d/01-forward.conf -
при загрузке не отрабатывает, приходится ручками запускать `sysctl
--system` .
Потом нашёл
https://www.altlinux.org/Etcnet#%D0%9E%D0%B1%D1%89%D0%B8%D0%B5_%D1%81%D0%B2%D0%B5%D0%B4%D0%B5%D0%BD%D0%B8%D1%8F
, где /etc/sysctl.d/ вообще не указан, зато есть /etc/net/sysctl.conf, в
котором есть строка
net.ipv4.ip_forward = 0
IMHO что-то тут неверно. Обрабатываются ли /etc/sysctl.d/*.conf ? Если
да - это нужно отразить в AltWiki
Также нужно либо дополнять man sysctl информацией про etcnet, либо в
/etc/net/sysctl.conf убирать "net.ipv4.ip_forward = 0" и другие ключевые
параметры в комментарий.
вот что было после перезагрузки:
[root@mail ~]# grep -R forward /etc/sysctl*
/etc/sysctl.d/01-forward.conf:net.ipv4.ip_forward=1
[root@mail ~]# sysctl -a | grep forward
