Paramiko：ssh.exec_command收集输出说明开放通道作为回应

Question

我有paramiko和ssh的python脚本，如下所示

import paramiko

# setup ssh connection this works. no problem.
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
conn = ssh.connect(MACHINEIP, username=ROOTUSER, password=ROOTUSER_PASSWORD, port=22)

# This first ssh exec works perfect. 
(sshin1, sshout1, ssherr1) = ssh.exec_command(cmd1)

# When I print the output of 2nd and 3rd ssh exec, I get output saying of channel open
(sshin2, sshout2, ssherr2) = ssh.exec_command(cmd2)
print sshout2
(sshin3, sshout3, ssherr3) = ssh.exec_command(cmd3)
print sshout3

当exec_command被多次使用以收集输出时，输出中的通道打开消息：

<paramiko.ChannelFile from <paramiko.Channel 2 (open) window=2097152 
   -> <paramiko.Transport at 0x1d42bd0L (cipher aes128-ctr, 128 bits) 
(active; 1 open channel(s))>>>

<paramiko.ChannelFile from <paramiko.Channel 6 (open) window=2097152 
   -> <paramiko.Transport at 0x1d42bd0L (cipher aes128-ctr, 128 bits) 
(active; 2 open channel(s))>>>

如何关闭此开放频道？或者有任何解决方案？我使用的是python 2.7。

应该用作sshout.read()而不是仅在打印时使用sshout。
