可以在活动连接期间通过 ssh 复制文件 [英] Is possible to copy files over ssh during an active connection

问题描述

我经常需要从 ssh 连接复制文件.让我们说一个 mysql 转储.我要做的是

Very often I need to copy a file from a ssh connection. Lets say a mysql dump. what I do is

local $ ssh my_server
server$ mysqldump database >> ~/export.sql
server$ exit
local $ scp myserver:~/export.sql .

我知道 ssh 有很多功能，例如 ssh-agent、端口转发等，我想知道是否可以从服务器执行 scp 以复制到我的本地计算机(无需创建另一个 ssh 连接).

I know ssh has a lot of features like ssh-agent, port-forwarding, etc, and I was wondering if there is anyway to execute scp FROM the server to copy to my local computer (without creating another ssh connection).

总结一下，是的，可以使用远程端口转发:

Summed up, yes it is possible using remote port forwarding:

[local] $ ssh -R 2222:xyz-VirtuaBox:22 remote
[remote]$ scp -P 2222 /home/user/test xyz@localhost:/home/user
