当我使用 RSA 密钥和 ssh 配置文件通过 Fabric 连接到多个服务器时出现错误。我的客户是雪豹 10.6.8，带有 python 2.7.2、Fabric 1.4.0、ssh（库）1.7.13。我使用多个带有密码的 RSA 密钥（不使用密码是不可能的）。我将密码添加到 ssh-add。我可以毫无问题地通过 ssh 连接到我的所有服务器。我将 env.use_ssh_config = True 添加到我的 fab 文件中以读取我的 ssh 配置文件。
当我使用 RSA 密钥（带有密码）连接到一台服务器时，一切正常。
但是当我连接到 2 台或更多主机时，我不断收到第二台服务器的“登录密码”。
fab -H server1,server2 test

我的fabfile
from fabric.api import *
import ssh
ssh.util.log_to_file("paramiko.log", 10)
env.use_ssh_config = True
def test():
run('uname -s')
我的 ssh 配置文件
Host server1
HostName xx.xx.xx.xx
Port 6666
User AB1
HashKnownHosts yes
PreferredAuthentications publickey
AddressFamily inet
Host server2
HostName xx.xx.xx.xx
Port 6666
User BC2
HashKnownHosts yes
PreferredAuthentications publickey
AddressFamily inet
在我的 ssh 配置文件中，我尝试删除“HashKnownHosts yes”，但这并没有改变任何东西。

两台服务器的 SSH 代理密钥 0273aff478dddddd05378738dhe98798 相同。它在第一台服务器上连接，但在第二台服务器上失败。我尝试以不同的顺序使用不同的服务器，但我总是遇到同样的问题，即面料要求第二台服务器的密码。
我怎样才能解决这个问题？
谢谢
