我正在使用下面的python代码连接到Windows远程共享。
self.connection = SMBConnection(
username=user,
password=password,
my_name=client_machine_name,
remote_name=server_name,
domain=domain,
use_ntlm_v2=True,
sign_options=2,
is_direct_tcp=True,
)
self.logger.info(
"Attempting to authenticate %s\%s on %s", domain, user, server_name
)
self.connection.connect(server_name, 445)
该代码由每日脚本使用，该脚本直到今天开始超时才可以正常工作。可能是什么原因？
nmap告诉我端口已打开
