使用paramiko库尝试SSH连接到Cisco ACS设备时,我遇到了以下错误。我以前在Python中使用paramiko没有问题,并且我可以从命令行或使用putty连接到这个盒子,但现在出现问题了。我已经打开了调试并将信息复制到这里。如果您能帮助我解决问题,请告诉我。
import paramiko
import sys
import socket
try:
paramiko.common.logging.basicConfig(level=paramiko.common.DEBUG)
sshConnection = paramiko.SSHClient()
sshConnection.set_missing_host_key_policy(paramiko.AutoAddPolicy())
sshConnection.connect('server',username='username',password='password')
except paramiko.BadAuthenticationType:
sys.stdout.write('Bad Password!\n')
sys.exit()
except paramiko.SSHException, sshFail:
sys.stdout.write('Connection Failed!\n')
sys.stdout.write('%s\n' % sshFail)
sys.exit()
except socket.error, socketFail:
sys.stdout.write('Failed to open socket\n')
sys.stdout.write('%s\n' % socketFail)
sys.exit()
并且调试输出返回:

我已确保安装了最新版本的pycrypto和paramiko。
