Memperoleh “Tidak dapat melakukan TUNSETIFF tun: Operasi tidak diizinkan” ketika mencoba terhubung ke OpenVPN

Saya mencoba menyiapkan OpenVPN Access Server di AWS menggunakan pasar AMI, tetapi saya sedang berjuang untuk terhubung dengannya.

Server akses aktif dan berjalan. Saya juga menambahkan pengguna dengan Login Otomatis dan membuat konfigurasi dan sertifikat klien yang relevan.

Saya kemudian menyalin file-file tersebut ke mesin saya dan mencoba untuk terhubung menggunakan openvpn client.ovpntetapi mendapat output dan kesalahan berikut,

Adakah yang tahu apa masalahnya? Saya menganggap itu gagal membuat terowongan karena garis ERROR?

Saya menjalankan server versi 2.0.10 dan versi klien,

Terima kasih

Sepertinya ini masalah sudo yang sederhana.

sudo openvpn client.ovpn bekerja memperlakukan.

Menggunakan Linux Mint, dan menghubungkan melalui Network Manager UI (yang tidak meminta sudo pwd) - Saya berasumsi itu tidak perlu. Ternyata, ini masalah bagiku! Menghubungkan via sudodari terminal berfungsi dengan baik.
