python 操作ssh--有more用invoke_shell

# 实例化SSHClient
client = paramiko.SSHClient()
# 自动添加策略，保存服务器的主机名和密钥信息
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
loger.debug("hostname=%s username=%s password=%s" %(equ_ip_s,username_s,passwd_s))
# 连接SSH服务端，以用户名和密码进行认证
client.connect(hostname=equ_ip_s, username=username_s, password=passwd_s)
chan = client.invoke_shell()
chan.settimeout(9000)
#  设置结束条件
p = re.compile(r'xxx')
loger.debug("client is %s",client)
loger.debug("cmd is '%s'",cmd)
chan.send(cmd+'\n')
# chan.send(cmd+'\n')
result = ''
result = chan.recv(4096)
#  循环获取数据
while True:
    chan.send(" ")
    results = chan.recv(1024000)
    result += results
    if p.search(results):
        print len(result)
        print type(result)
        chan.send('q')
        break
# print result
# 拆分获取每行的数据
result2 = re.split(r'\r\n', result)
