用Python-Pexpect读取'ipconfig

Question

我在Windows XP上运行freeSSHd作为SSH服务器，经过身份验证的用户可以使用CMD命令行。我想在运行Python脚本时自动获取发送'ipconfig'命令的结果。连接已经成功建立，但我在读取每个字段的结果并将其放入不同变量时遇到了问题。我的代码输出的是'4'，而不是'10'（IP地址的第一个数字），我不知道这个4是从哪里来的。有没有什么想法？

Windows XP上ipconfig的输出

def sendcommand(conn,command):
    conn.sendline(command)
    conn.expect('\d')
    print conn.after

def c(ip,username,password):
    global conn
    ft = 'ssh '+username+'@'+ip
    print 'we are trying to connect to ' + ft
    new = 'Are you sure you want to continue connecting'
    conn = pexpect.spawn(ft)
    result = conn.expect([ pexpect.TIMEOUT , new ,'[P|p]assword:' ])
    if result == 0:
        print 'connection error'
        return
    if result == 1:
        conn.sendline('yes')
        result = conn.expect([ pexpect.TIMEOUT , '[P|p]assword:'])
    if result == 0:
        print 'connection error'
        return
    conn.sendline(password)
    conn.expect('>')
    sendcommand(conn,command)



def main ():
    global command
    username = 'hkhrais'
    ip = '10.0.2.10'
    password = 'hkhrais'
    command = ' ipconfig'
    c(ip,username,password)


 main ()

使用 WMI 要简单得多：

import wmi

def return_ip_addresses(user,passwd,machine):

    i = wmi.WMI(machine, user=user, password=passwd)

    addresses = []

    for interface in i.Win32_NetworkAdapterConfiguration(IPEnabled=1):
      for ip_address in interface.IPAddress:
         addresses.append(ip_address)

    return addresses

if __name__ == '__main__':      
   print return_ip_addresses('user','secret','10.1.1.1')
