centos – 无法连接到端口4430上的localhost
作者：互联网
我正在安装CentOS和Nginx的虚拟盒子中运行vagrant.我已经创建了从vagrant box到远程服务器的反向隧道,但是当我尝试连接到端口4430上的localhost时,我在运行命令时遇到以下错误：
curl -v 'https://localhost:4430'
* About to connect() to localhost port 4430 (#0)
* Trying ::1... Connection refused
* Trying 127.0.0.1... Connection refused
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host
我一直在尝试在浏览器中加载网站,但Chrome也会抛出错误.
This webpage is not available
ERR_CONNECTION_REFUSED
我想要做的是创建一个反向隧道似乎工作正常,我可以连接到远程机器并创建隧道,但我无法浏览我的本地机器上所需的(反向端口).
这是我的隧道脚本：
ssh -v -R 4430:localhost:443 user@remote-domain.com -N
有谁知道这个问题是什么？
我可以使用端口443而不是4430连接！
任何帮助,将不胜感激！
UPDATE
运行以下命令将提供以下输出
ssh -v -R 4430:localhost-domain:443 ec2-user@vm.domain.com -N

我在想LOCALHOST：4430应该是流浪盒的主机名吗？例如,本地域名：4430
解决方法:
我认为你缺少-g选项,因为否则远程端口只会在localhost上侦听,这意味着远程localhost之外的任何其他主机都无法连接到它.
使用-g它会监听0.0.0.0,这意味着它可以在所有接口上使用,而不仅仅是localhost.
正如ssh(1)所说的g选项“允许远程主机连接到本地转发端口.如果在多路复用连接上使用,则必须在主进程上指定此选项.”
您还提到您已经在流浪盒中创建了此隧道.所以这个卷曲你的展示也在流浪盒内,对吗？否则,如果您在主机系统上运行curl而不是在无法使用的vagrant box内运行curl.如果要从主机系统(不在流浪盒内)连接到隧道,则必须连接到流浪盒的IP而不是127.0.0.1.
