海康NVR(Network Video Recorder)是一种专门用于数字监控系统的设备,可对各种通用类型的网络视频设备进行实时监控、录制、回放和管理。具备如下特点:
SSH是专为远程登录会话和其他网络服务提供安全性的协议,利用SSH协议可以有效防止远程管理过程中的信息泄露问题。
海康NVR启用SSH模式后,只有通过SSH协议连接并输入正确的用户名和密码,才能进行远程访问和管理,可以有效提供远程管理过程中的数据安全性。
海康NVR启用SSH模式后,可能会对设备的性能产生一定影响,如传输速度变慢、设备运行缓慢等。
另外,如果设备启用了SSH,但未及时更新或升级SSH,可能会被黑客攻击,从而导致数据泄露、设备损坏等问题。
首先从WEB界面登录海康NVR,如下图所示,依次点击“系统-安全管理-安全服务”,勾选“启用SSH”,然后点击“保存”。
三次连续SSH登录失败,会自动关闭SSH登录,需要重新回到Web网页勾选“启用SSH”的功能
SSH登录后,进入shell模式,不过默认进来时protect shell(psh)模式,这个模式下,很多shell指令无法执行或者无权限。
Protect Shell (psh)
Enter 'help' for a list of DVR/NVR system commands.
#
#
比如,show用户信息时,该指令会提示权限被拒绝。
# showUserInfo
Permission denied.
#
如果不清楚shell 指令,可以通过help提供帮助
1,GetAnrCfgInfo
可以获取通道信息,包括主码流,子码流等。
