OpenVPN Update resolvconf

This is a script to update your /etc/resolv.conf with DNS settings that come from the received push dhcp-options. Since network management is out of OpenVPN client scope, this script adds and removes the provided from those settings.

However if you have systemd 229 or newer the better option is to use script from https://github.com/jonathanio/update-systemd-resolved which uses DBus calls instead of creating temporary *.network files.

Place the script in /etc/openvpn/update-resolv-conf.sh or anywhere the OpenVPN client can acess.

Add the following lines to your client configuration:

# This updates the resolvconf with dns settings setenv PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin script-security 2 up /etc/openvpn/update-resolv-conf.sh down /etc/openvpn/update-resolv-conf.sh down-pre 

Just start your openvpn client with the command you used to do.

Alternatively, if you don’t want to edit your client configuration, you can add the following options to your openvpn command:

--setenv PATH '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin' --script-security 2 --up /etc/openvpn/update-resolv-conf.sh --down /etc/openvpn/update-resolv-conf.sh --down-pre 

For bugs and another questions open a ticket in the Isssues Page.

как создать /etc/openvpn/update-resolv-conf или как подружить openvpn и openresolv?

Options error: —up script fails with ‘/etc/openvpn/update-resolv-conf’: No such file or directory (errno=2) Options error: Please correct this error. Use —help for more information.

No such file or directory

да я догадался, что файла update-resolv-conf нет. я конечно могу его создать,но что в него прописать? или как заставить программы его сгенерировать?

Скопируй в update-resolv-conf, сделай исполняемым. В resolv.conf пропиши nameserver 8.8.8.8

ОС какая? update-resolv-conf из коробки есть только в Debian и Ubuntu. Если openvpn его требует, значит он прописан в конфиг файле (некоторые VPN поставщики добавляют), убери его оттуда, а DNS настраивай сам в /etc/resolv.conf. Или настраивай VPN через Network Manager. Или как тебе посоветовали, подсунь свой update-resolv-conf по тому пути, который ждет openvpn, правда не факт что заведется.

не дебиан или убунту) спасибо,удалил из своего ovpn файла строчки про ресолв, и заработало
