я имею ввиду на автомате. нужно чтобы система сама определяла ip и через api меняла ip в dns
как это сделать?
мне "придется мучаться со скриптами обновления ДНС" потому что выделенный ip не дают. Возможно есть варианты как сделать такой скрипт и из чего?
Можно попобробнее про "Настраиваете подключение сервера к впн"? Я например в centos через yum ставил openvpn но как сервер, а как сделать как клиент? Или тут только если поставить виндовый сервер для vpn-клиента и подключаться?
С полицией стоит связываться? Мне их почту дали. И если стоит, то как им написать есть ко мне претензии или нет?
Это был closeclub.pro
Потом он уехал в Польшу, а сейчас вообще не открывается. В тюрьме что ли уже админ ☝
Через сутки добился официального отсканеного письма.Написано, что 4 месяца назад хостился кардинг-форум (по жалобе он тогда был заблокирован и УДАЛЁН) и завели уголовное дело. Примерно неделю назад был подписан ордер о изъятии сервака из ДЦ, чтобы как там написано "узнать владельца кардинг-форума (по возможности снять копию сайта)".
спасибо. установил. поанализировал. на сервере vps, на ней торрент трекер, куча такого в логах:
tcp 6 316983 ESTABLISHED src= dst= sport=61229 dport=777 src= dst= sport=777 dport=61229 [ASSURED] mark=0 secmark=0 use=2^C
почитал что:
On 128 MB of RAM you will get 8192 possible entries, and at 256 MB of RAM, you will get 16376 entries.
и пересчитал на свою 48гиговую память на ноде получается 3145728 в nf_conntrack_max. Правильно посчитал? Или нужно считать по памяти vps? Или по свободной памяти на ноде? На ноде все 48гиг могут использоваться так как kvm.
