這是我的 OpenVPN 伺服器設定（完美運行）

我想允許使用具有不同用戶名的相同客戶端。所以我編輯了配置並在 server.conf 檔案中添加了以下幾行
script-security 2 # must be at least 2
auth-user-pass-verify /home/forge/scripts/checkUser.sh via-file
username-as-common-name # without this openvpn will use cn in the certificate as username
duplicate-cn # you may need this if everyone is using same certificate
透過在設定中新增此（上面）內容，openvpn 伺服器拒絕啟動。
為了調試，我對上面幾行進行了註釋，並一一取消註釋。所以現在我可以確定是該線路auth-user-pass-verify /home/forge/scripts/checkUser.sh via-file導致了問題。
沒有任何線索說明為什麼它在systemctl statusor中失敗journalctl -xe。該文件checkUser.sh可由系統中的任何使用者完全執行。日誌檔status-server.log也是空的。
雖然sudo systemctl start openvpn-server失敗，但直接運行 openvpn 可以：sudo openvpn --config /etc/openvpn/server/server.conf！
看起來是這樣的：/lib/systemd/system/[email protected]
