Question

环境： Python：2.7.6 帕拉米科：1.13.0 目标SSH服务器：Cisco MDS NX-OS 6.2（3）

代码：

import paramiko
import StringIO
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect("switchname", username="username", password="password")
stdin, stdout, stderr = ssh.exec_command("term length 0")
stdin, stdout, stderr = ssh.exec_command("show zoneset active")    
t = stdout.read()
ssh.close()

for line in StringIO.StringIO(t):
    line = line.replace("\n","")
    print line

它只产生几行输出而不是整个输出。如果我修改上面的代码并添加一个ssh.exec_command，如下所示。

代码：

import paramiko
import StringIO
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect("switchname", username="username", password="password")
stdin, stdout, stderr = ssh.exec_command("term length 0")
stdin, stdout, stderr = ssh.exec_command("show zoneset active")    
stdin2, stdout2, stderr2 = ssh.exec_command("show version ")    
t = stdout.read()
ssh.close()

for line in StringIO.StringIO(t):
        line = line.replace("\n","")
        print line

产生以下错误：

Traceback (most recent call last):
  File "paramiko_issue.py", line 15, in <module>
    stdin, stdout, stderr = ssh.exec_command("show zoneset active")
  File "build/bdist.macosx-10.9-intel/egg/paramiko/client.py", line 307, in exec_command
  File "build/bdist.macosx-10.9-intel/egg/paramiko/transport.py", line 543, in open_session
  File "build/bdist.macosx-10.9-intel/egg/paramiko/transport.py", line 607, in open_channel
paramiko.ssh_exception.SSHException: SSH session not active

我非常感谢您解决此问题的任何帮助。提前谢谢。

Python paramiko没有提供完整的输出，我相信会话意外关闭
