NetWorker：AUTHC 连接失败并显示 HTTP 400/403 错误

The NetWorker nsrlogin 命令失败并显示 HTTP 400 或 403：

nsrlogin -u administrator
130136:nsrlogin: Please enter password:
117849:nsrlogin: Authentication library error: CONNECT tunnel failed, response 403
Server Message : Make sure that server is running

或者：

nsrlogin -u Administrator
130136:nsrlogin: Please enter password:
117849:nsrlogin: Authentication library error: CONNECT tunnel failed, response 400
Server Message : Make sure that server is running

NetWorker 身份验证和其他连接到身份验证服务的尝试失败，并显示类似的错误。

nsrauthtrust -H NETWORKER_SERVER_NAME -P 9090
125927:nsrauthtrust: Failed to retrieve certificate: CONNECT tunnel failed, response 403

NetWorker Management Console （NMC） 和 NetWorker Web 用户界面 （NWUI） 升级 （Windows） 和升级后脚本 （Linux） 报告 AUTHC 端口上的连接故障。

此问题发生在 NetWorker 之外。The NetWorker nsrlogin 命令还报告“Connect Tunnel Failed”（连接隧道失败），因为环境中配置了 HTTPS 代理。可以使用 curl 命令执行此操作：

curl https://NETWORKER_SERVER_ADDRESS:9090

返回的具体错误可能因所使用的特定代理供应商和配置而异。它们的共同点是，您会看到通过 HTTPS 代理主机重定向到 NetWorker 身份认证 （AUTHC） 端口（默认值 9090）的通信。返回的错误是 HTTP 4xx 错误;400（错误请求）或 403（禁止）。

专门针对端口 9090 上的身份验证流量使用 HTTPS 代理未明确记录或测试为受支持的配置。NetWorker 组件通常期望服务之间直接通信，尤其是对于身份验证。

删除 NetWorker 服务器上的 HTTP/HTTPS 代理配置。还必须从与 NetWorker 服务器上的端口 9090 通信的任何 NetWorker 主机中删除此项。请参阅：NetWorker 进程和端口

在 NetWorker 服务器上运行：

unset https_proxy
unset http_proxy

取消设置变量后，尝试 nsrlogin 再。如果成功，请运行 nsrlogout。

[admin@lnx-srvr01 root]$ nsrlogin -u Administrator
130136:nsrlogin: Please enter password:
Authentication succeeded

[admin@lnx-srvr01 root]$ nsrlogout

这表示与 NetWorker AUTHC 服务的通信正常运行。涉及 NetWorker 身份验证或通过端口 9090 进行通信的其他进程预计会成功。

而 unset 命令仅取消设置当前 shell 会话的变量。如果设置为系统或配置文件变量，它们会在您打开终端、重新启动系统或启动新的 shell 会话时自动加载。必须执行以下作，以防止在下一次会话或重新引导时加载变量。

Windows： 检查 SYSTEM 或 USER 变量，并删除用于定义 HTTP/HTTPS 代理主机的任何变量。

Linux：检查以下文件中是否有任何 HTTP/HTTPS 变量设置并将其删除： 

• ~/.bashrc
• ~/.bash_profile
• ~/。轮廓
• /etc/environment
• /etc/profile
• /etc/profile.d/*.sh
