__main__ 需求 tts auto att inf 登錄 == not
需求:python如何實現普通用戶登錄服務器後切換到root用戶再執行命令
解決參考:
代碼:
def verification_ssh(host,username,password,port,root_pwd,cmd): s=paramiko.SSHClient() s.load_system_host_keys() s.set_missing_host_key_policy(paramiko.AutoAddPolicy()) s.connect(hostname = host,port=int(port),username=username, password=password)if username != ‘root‘: ssh = s.invoke_shell() time.sleep(0.1) ssh.send(‘ export LANG=en_US.UTF-8 \n‘) #解決錯誤的關鍵,編碼問題 ssh.send(‘su - \n‘) buff = "" while not buff.endswith(‘Password: ‘): #true resp = ssh.recv(9999) print(resp) buff+=resp.decode(‘utf8‘) print(‘hhhhh‘) print(buff) ssh.send(root_pwd) ssh.send(‘\n‘) buff = "" # n = 0 while not buff.endswith(‘# ‘): # n += 1 resp = ssh.recv(9999) print(resp) buff +=resp.decode(‘utf8‘) # print(n) # if n >=3: # break # print(buff) ssh.send(‘sh /tmp/check/101.sh‘) #放入要執行的命令 ssh.send(‘\n‘) buff = ‘‘ # m = 0 while not buff.endswith(‘# ‘): resp = ssh.recv(9999).decode() buff +=resp # m += 1 # print(m) result = buff # print(type(result)) # print(result) s.close() if __name__ == "__main__": verification_ssh(‘172.25.240.164‘, ‘cattsoft‘, ‘Cat@2018‘, ‘52222‘, ‘Huawei12#$‘, ‘id‘)
遇到問題:
思路:經過檢查發現這個是中文字符集和英文字符集返回密碼格式不同導致的,在代碼中加入:ssh.send(‘ export LANG=en_US.UTF-8 \n‘),即可解決上述問題
因為中文和英文字符集轉換不同,所以導致報錯。
