我有一個名為 creds.txt 的文本文件，格式如下。我希望能夠向我的 ssh 服務器提供帶有憑據的文本文件，并運行所有這些服務器的命令，以便更輕松地設置大量 ssh 服務器。username:password:ip我運行了下面的代碼import paramikowith open('creds.txt', 'r') as file:    for line in file:        usrname, passwd, ip = line.split(':')        print("[!] trying " + usrname + " and " + passwd + " for " + ip)        ssh_client = paramiko.SSHClient()        ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy)        ssh_client.connect(hostname=ip, username=usrname, password=passwd, port=22)        command = "ls"        stdin,stdout,stderr = ssh_client.exec_command(command)        stdout = stdout.readlines()        print (stdout)        print("[+]connection succsessfull to " + ip + " with " + usrname + ":" + passwd)        paramiko.agent.Agent.close我收到錯誤Traceback (most recent call last):  File "c:/Users/XXXX/Desktop/code projects/XXXX/XXXXXXXX.py", line 9, in <module>    ssh_client.connect(hostname=ip, username=usrname, password=passwd, port=22)  File "E:\python\lib\site-packages\paramiko\client.py", line 340, in connect    to_try = list(self._families_and_addresses(hostname, port))  File "E:\python\lib\site-packages\paramiko\client.py", line 203, in _families_and_addresses    addrinfos = socket.getaddrinfo(  File "E:\python\lib\socket.py", line 918, in getaddrinfo    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):socket.gaierror: [Errno 11001] getaddrinfo failedPS C:\Users\Jaden\Desktop\code projects\net>我在沒有文本文件代碼的情況下運行了它，它工作得很好，但是當我添加文件解釋功能時，它停止工作。
