无法与 rsync 共享 ssh 连接

Question

在我的.ssh/config文件中，我有以下内容：

Host xxx
User yyy
HostName zzzz
ControlMaster auto
ControlPath ~/.ssh/%r@%h:%p 

这非常适合多路复用我的 ssh 连接（即登录一次，并与多个会话共享连接）。

我想将我的 ssh 连接与rsync多路复用（共享），以便我可以执行以下操作

rsync -arv -e ssh xxx:/source target

并且不必通过rsync登录（我有 XXX 的双因素身份验证系统，如果我在使用 rsync 时可以跳过它会很棒）。

更新：我了解到默认情况下 rsync 会首先尝试重新使用连接。所以我不确定为什么它不起作用。这是我尝试的详细输出：

> rsync -arv -e 'ssh -v' XXX:~/file ~/temp/.

Answer 1

我刚刚尝试过这件事，它对我有用。

注意：我还应该指出，在运行下面的命令之前，我运行了此命令，该命令在远程主机上设置用户帐户，以便与我的本地用户帐户的 ssh 凭据一起使用。

ssh-copy-id root@skinner

我的设置如下：

$HOME/.ssh/config:

Host *
ControlMaster auto
ControlPath ~/.ssh/master-%r@%h:%p
IdentityFile ~/.ssh/id_dsa

Host skinner mulder byers
    User root

内容$HOME/.ssh/：

$ ls -dl ~/.ssh
drwx------ 2 saml saml 4096 May 23 03:18 /home/saml/.ssh

$ ls -l ~/.ssh
total 16
-rw------- 1 saml saml 204 May 23 03:17 config
-rw------- 1 saml saml 736 Jan 10  2011 id_dsa
-rw-r--r-- 1 saml saml 612 Jan 10  2011 id_dsa.pub
-rw-r--r-- 1 saml saml 401 May 23 03:17 known_hosts

现在通过 ssh 连接到 Skinner 主机：

$ ls -l ~/.ssh
