Unexplained timeout when connecting to a windows share via Python - pysmb
0
I am using the below python code to connect to a windows remote share.
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)
The code is used by a daily script which was working fine until today, when it started timing out. What could be the reason?
nmap tells me that the port is open
Host is up (1.0s latency).
