我收到以下错误：

    sudo ionice -c 3 nice -n +19 rsync -av --progress -e 'ionice -c 3 nice -n +19 ssh -l root -p 22 192.168.0.1' 192.168.0.1:/domains/remote/. /domains/local/;
root@192.168.0.1's password:
bash: 192.168.0.1: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: remote command not found (code 127) at io.c(605) [Receiver=3.0.9]

rsync 工作较早，现在我收到此错误。

编辑1：

root@local-debian7:/root# rsync -av --progress -e 'ssh -l root -p 22 192.168.0.1' 192.168.0.1:/domains/remote/. /domains/local/;
root@192.168.0.1's password:
bash: 192.168.0.1: command not found
rsync: connection unexpectedly …

我怎么解决这个问题？我有一个 bash 脚本（在 Ubuntu Server 下），执行多个 SSH 连接，执行一些远程传输，例如 rsync 多次。

我的问题是，我想避免多次输入密码。但是我不想使用SSH公钥交换，因为如果有人拥有密钥，就可以连接远程计算机。

我想要以下内容：

• 当我启动 bash 脚本时 SSH 应该询问密码
• 重用密码，所以在超时之前不要再次询问密码
• 超时结束后，再次询问密码。

类似的东西，sudo 是如何工作的，只是使用 ssh。

知道如何解决这个问题吗？

编辑1：

我发现了一个名为 ssh 多路复用的新 SSH 功能。也许使用这个我可以达到我想要的目标。

这行得通吗？

使用 Debian Stretch v9.11。

我尝试安装 build-essential，但由于未满足的依赖关系而失败：

我在 Debian 9.12 中遇到以下 libc6 依赖问题。
