Question

我正在尝试在远程EC2实例上使用rsub。

我使用

连接到它

ssh -i keyPair.pem -R 52698:localhost:52698 ubuntu@address.amazonaws.com

然而，当我成功连接到实例时，我得到了欢迎的错误：

警告：侦听端口52698的远程端口转发失败

rsub的目标是设置一个隧道，以便能够通过GUI从ssh编辑远程文件。

欢迎任何有关此错误的帮助！

详细错误（-v）是：

Answer 1

if ("Parent".equals(auth_user)) {

看起来您正在尝试打开两个不同的端口转发（debug1: remote forward success for: listen 52698, connect localhost:52698 debug1: remote forward failure for: listen 52698, connect 127.0.0.1:52698 Warning: remote port forwarding failed for listen port 52698和localhost），它们基本相同。您是否也在127.0.0.1设置了转发功能？使用~/.ssh/config运行可能会显示更多信息。

也可以使用-vvv中的AllowTcpForwarding在服务器上禁用它。
