从开发人员(项目1)和系统管理员(项目2和3)的角度进行故障排除:
- 通过启用Java的SSL握手调试
-Djavax.net.debug=ssl:handshake:verbose
。
- 如果在执行以下步骤时在密码中观察到,则
sudo apt install ssldump
通过以下链接通过以下链接在服务器上安装ssldump 或通过源链接进行编译Unknown value
。
- 在服务器上,
sudo ssldump -k <your-private-key> -i <your-network-interface>
- 检查有关失败的真正原因的日志。
ssldump日志无法正常握手的示例:
