用python寫一個ssh連線到DUT－阿藏哥的部落格~不應該阿

小篇利用python寫一個SSH連線
結果它一般linux不一樣
沒辦法用
stdin, stdout, stderr = ssh.exec_command(command)
又很多篇都用這個例子,誤我很時間
最後改寫如下,用來取代putty的ssh連線的功能
import paramiko
import  time


#comand為命令的副程式
def command(comand):
    channel.send(comand)
    channel.send("\n")
    time.sleep(5)
    if comand =="tree" or "uci" or "sh":
        res = channel.recv(65535).decode('utf8')
    else:
        res = channel.recv(65535)

    print(res)
    print('**********************************************************')


# 定義 syslogin.log來記錄
paramiko.util.log_to_file('syslogin.log')
# 定義 ssh 為使用 paramiko.SSHClient()
ssh = paramiko.SSHClient()
# 設定自動加入 遠端主機的 SSH Key
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())




 # 設定連接 ssh 的主機名稱, 使用者名稱, s密碼
ssh.connect('192.168.2.100', port=22,username='araknis',password='araknis', timeout=4)
print('start connect to dut')
print("===========================welcom to CLI===============================")


#一開始會卡住 ,作一些處理
stdin, stdout, stderr = ssh.exec_command('',get_pty=True)
#print(stdin.channel.eof_received)
timeout = 5
endtime = time.time() + timeout
while not stdout.channel.eof_received:
   time.sleep(1)
   if time.time() > endtime:
     stdout.channel.close()
     break
#stdout.read()
#stdout.flush()
print(stdout.read())
#nbytes = 0
#time.sleep(2)
#print("===========================welcom to CLI===============================")

channel = ssh.invoke_shell()


T=True

while (T==True):
    com=input(" please input command: ")
    command(str(com))
    time.sleep(2)
    q="reboot"
    q1="logout"
    if(str(com)== q or str(com)== q1  ) :
        T=False
    print(T)
channel.close()
