plink -获得连续输出

Question

我在python脚本中使用plink.exe向路由器发送命令。我在"output“中得到结果。一条命令会触发路由器自己运行一系列命令。有没有办法连续获得输出，直到所有命令都完成。我只将前几行返回到输出中。

comm = "plink.exe -pw admin admin@172.16.0.1 COMMAND"
b = sub.Popen(comm,stdout=sub.PIPE,stderr=sub.PIPE)
output, errors = b.communicate()

print output

我希望这对某些人有任何意义。=)

我找到了我的问题的答案。Paramiko模块为我工作。=)

import sys
import time
import paramiko

host = '192.168.1.1'
user = 'admin'
pwd = 'admin'
i = 1

#def interactive_shell():
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

transport = paramiko.Transport((host,22))
transport.connect(username=user, password=pwd)
time.sleep(0.2)
#chan = paramiko.transport.open_session()
chan = transport.open_session()
chan.setblocking(0)
chan.invoke_shell()
chan.send("command") # Send command to device
chan.send("\n") # Send Enter
time.sleep(1)  #optional
while not chan.exit_status_ready():
    time.sleep(0.1)
    if chan.recv_ready() :
        output = chan.recv(8192)
        if len(output) > 0 :
           outputLines = output.splitlines(True)
           sys.stdout.write(output)

        if "unit" in output:
            sys.stdout.flush()
            break

    if chan.recv_stderr_ready() :
        mystderr = chan.recv_stderr(8192)
        if len(mystderr) > 0 :
            print mystderr, ","

transport.close()
