Connecting to Firebird database using Kinterbasdb+Python
Hi, I've been using FB1.5 and access the database using Kinterbasdb + Python. My connection is established using kinterbasdb.connect() method and the parameters host, dns, database, user, password are all defaulted to 'None'. On my own machine running Mac OSX 10.3, I can connect using the following: host = 'localhost' database = '' user = '' password = '' At the same time, I can also connect if I set host=None on my machine. However, I cannot use 'localhost' on a shared Linux machine (not allowed. Don't ask why, system admin's mandate. And the Linux machine is without inetd). So when I set host=None, I get this error: Connecting to Muscopedia Database Connection: localhost:/mnt/disk/home/mling/muscorian/BioDatabases/muscopedia.fdb:mouse:mouse <-- default None <-- actual host (with 'print self.dbhost' where kinterbasdb.connect(host = self.dbhost,.) OperationalError (-902, 'isc_attach_database: Unable to complete network request to host "localhost".. Failed to establish a connection.. Connection refused. ') File "muscorian.py", line 641, in main result = mosys.run(command) File "muscorian.py", line 597, in run elif (command[0] == 'linkmuscopedia'): self.commandLinkMuscopediaDB(command) File "muscorian.py", line 129, in commandLinkMuscopediaDB self.muscopedia = PubMedGrabber.FBUtilities(str(command[1])) File "abcrawl/PubMedGrabber.py", line 340, in __init__ user = self.dbuser, password = self.dbpwd, charset='UNICODE_FSS') File "/usr/lib/python2.2/site-packages/kinterbasdb/__init__.py", line 470, in connect return Connection(*args, **keywords_args) File "/usr/lib/python2.2/site-packages/kinterbasdb/__init__.py", line 608, in __init__ self._C_con = _k.attach_db(dsn, dpb, dialect) Any ideas or solutions? Thanks in advance. Cheers maurice -- http://mail.python.org/mailman/listinfo/python-list

So when I set host=None, I get this error: Just for my understanding: if you start your script on the machine hosting the DB you're able to connect. If you start it on a different machine, you are not able to connect without giving a hostname? Whats wrong with offering the the name (or IP-address) of your MacOS-box instead of 'localhost' to the script? Mathias -- http://mail.python.org/mailman/listinfo/python-list

How is your Firebird database configured -- Classic Server or Super Server? If it's in classic server mode, you don't need to worry about the host portion. You do need to worry about permissions on the database file. I got it to work by making it 664 and owner + group firebird. Grig -- http://mail.python.org/mailman/listinfo/python-list

So, the DB and the program are also on the same Linux machine. On the Linux machine, I cannot use localhost, so I set host parameter in kinterbasdb.connect() method to None, which is the default kinterbasdb uses. On Linux machine, I get the error as posted. On my Mac OSX machine, initiating host parameter to 'localhost' or None has no difference, it works. Thanks and cheers Maurice -- http://mail.python.org/mailman/listinfo/python-list

How do you connect to the Linux-DB using tools like isql? Check you firebird config (most likely in /etc/firebird2/firebird.conf) for the parameters "RemoteServicePort" and "RemoteBindAddress". And at least try "netstat -alp | grep fbserv" (as root) to check if the firebird is running properly. If you're running the classic server you can simply follow Grig's advice and connect "directly" to the db files. Mathias -- http://mail.python.org/mailman/listinfo/python-list
