根据您提供的信息,看起来您尝试使用SSH连接到主机lxslc702.ihep.ac.cn的端口22,但连接被远程服务器关闭了。关闭连接的原因可能有很多,例如网络问题、身份验证失败或服务器配置问题。要进一步诊断此问题,您可以尝试以下步骤:
1. 确保网络连接正常:检查您的网络连接是否正常,确保您可以访问远程服务器。
2. 检查身份验证凭证:确保您使用的身份验证凭证(例如用户名和密码、SSH密钥)是正确的,并且具有连接到远程服务器的权限。
3. 检查远程服务器配置:如果您有权限访问远程服务器的配置文件,请检查是否存在任何配置问题,例如防火墙设置、访问限制或SSH服务配置。
如果您仍然遇到问题,建议联系远程服务器的管理员或技术支持人员以获取更多帮助和支持。
