我尽量让一个SSH登录到Cisco设备，这将失败，并paramiko.SSHClient。SSH登录与python.paramiko模块插入思科设备出现故障
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
transport = ssh.get_transport()
ssh.connect(hostname, username='user', password='pwd')
ssh.close()
随着paramiko.DEBU开启：

我试图做一些与交通运输但是
transport = ssh.get_transport()
运输无。
但是，如果我试图通过的paramiko提供的simple_demo连接我可以连接。 下面的代码工作：
# get host key, if we know one
hostkeytype = None
hostkey = None
try:
host_keys = paramiko.util.load_host_keys(os.path.expanduser('~/.ssh/known_hosts'))
except IOError:
try:
# try ~/ssh/ too, because windows can't have a folder named ~/.ssh/
host_keys = paramiko.util.load_host_keys(os.path.expanduser('~/ssh/known_hosts'))
except IOError:
print '*** Unable to open host keys file'
host_keys = {}
if host_keys.has_key(hostname):
hostkeytype = host_keys[hostname].keys()[0]
hostkey = host_keys[hostname][hostkeytype]
print 'Using host key of type %s' % hostkeytype
# now, connect and use paramiko Transport to negotiate SSH2 across the connection
try:
t = paramiko.Transport((hostname, port))
t.connect(username='user', password='pwd', hostkey=hostkey)
t.close()
except Exception, e:
print '*** Caught exception: %s: %s' % (e.__class__, e)
traceback.print_exc()
try:
t.close()
except:
pass
sys.exit(1)
但我想我会更愿意使用SSHClient。这就是为什么我将不胜感激任何帮助。
谢谢。
