使用RSA密钥和ssh配置文件连接到Fabric的多个服务器时出错。 我的客户端是雪豹10.6.8，python 2.7.2，Fabric 1.4.0，ssh（library）1.7.13。 我使用带密码的多个RSA密钥（不能使用密码短语）。我将我的密码添加到ssh-add中。我可以毫无问题地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，我会继续获得第二台服务器的“登录密码”。
fab -H server1,server2 test
[server1] Executing task 'test'
[server1] run: uname -s
[server1] out: Linux
[server2] Executing task 'test'
[server2] run: uname -s
[server2] Login password:
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”，但这并未改变任何内容。

SSH代理密钥0273aff478dddddd05378738dhe98798对于两个服务器都是相同的。它连接在第一台服务器上但在第二台服务器上失败。我尝试了不同的服务器，不同的订单，但我总是遇到同样的问题，织物要求第二台服务器的密码。
我该如何解决这个问题？
谢谢
