Hi, I want to set up an API to MonetDBwith Python. I have followed the instructions（https://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/Python）and plan to make connection to my DB with this Python statement: import pymonetdb; connection=pymonetdb.connect(username="monetdb",password="monetdb",hostname="127.0.0.1",database="testdb") But I got the following ERROR: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/lingbin/maizegenome/maizedbfarm/testpy/local/lib/python2.7/site-packages/pymonetdb/__init__.py", line 48, in connect return Connection(*args, **kwargs) File "/home/lingbin/maizegenome/maizedbfarm/testpy/local/lib/python2.7/site-packages/pymonetdb/sql/connections.py", line 55, in __init__ unix_socket=unix_socket, connect_timeout=connect_timeout) File "/home/lingbin/maizegenome/maizedbfarm/testpy/local/lib/python2.7/site-packages/pymonetdb/mapi.py", line 139, in connect self.socket.connect((hostname, port)) File "/usr/lib/python2.7/socket.py", line 228, in meth return getattr(self._sock,name)(*args) socket.error: [Errno 111] Connection refused Do you have a hint for me how to solve this error? Many thanks, Lingbin
