WSL2 SSH RemoteForward连接回

Question

在签出开发服务器上的分支后，我尝试使用开发服务器上的rsync将文件下载到本地计算机。

在使用wsl2之前，我曾经能够完成以下操作：

远程服务器

rsync -ave "ssh -p 22001" --delete --exclude-from ~/rsync_exclude_list.txt ~/as/ alex@localhost:/home/alexmk92/code/project

本地SSH配置

Host dev-tunnel
    HostName dev.sever.co.uk
    User as
    ControlMaster auto
    ControlPath ~/.ssh/sockets/%r@%h:%p
    RemoteForward 22001 localhost:22

Host dev
    HostName dev.server.co.uk
    User as
    RequestTTY yes
    RemoteCommand cd as; bash

然后，我可以使用ssh dev和ssh -fvN dev-tunnel运行这些，如果在远程服务器上输入ssh -p 22001 alex@localhost，则得到：

debug1: remote forward success for: listen 22001, connect localhost:22
debug1: All remote forwarding requests processed
debug1: client_input_channel_open: ctype forwarded-tcpip rchan 2 win 2097152 max 32768
debug1: client_request_forwarded_tcpip: listen localhost port 22001, originator 127.0.0.1 port 34472
debug1: connect_next: host localhost ([127.0.0.1]:22) in progress, fd=5
debug1: channel 1: new [127.0.0.1]
debug1: confirm forwarded-tcpip
debug1: channel 1: connection failed: Connection refused
connect_to localhost port 22: failed.
debug1: channel 1: free: 127.0.0.1, nchannels 2

我猜这是因为WSL2不再在本地主机上运行，而是在Hypervisor中被隔离。这可能意味着windows在localhost:22 (没有运行SSH服务器的地方)接收到这个请求，然后挂断连接。

如何将请求转发到我的WSL2 SSH进程？

Answer 1

可以使用以下WSH脚本向WSL2机器添加端口映射：

$port = 3000;
$addr = '0.0.0.0';
$remoteaddr = bash.exe -c "ifconfig eth0 | grep 'inet '"
$found = $remoteaddr -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';

if( $found ) {
  $remoteaddr = $matches[0];
} else {
  echo "Error: ip address of WSL 2 cannot be found";
  exit;
}
Invoke-Expression "netsh interface portproxy delete v4tov4 listenport=$port listenaddress=$addr"
Invoke-Expression "netsh interface portproxy add v4tov4 listenport=$port listenaddress=$addr connectport=$port connectaddress=$remoteaddr"

echo "Success: Port mapping added!";

当然，您需要更改为端口，也许IP地址(前两行)可能需要以管理员的身份运行脚本.
