SELinux status:                 disabled

There are just two records in that table, "Greylisting Inbound Emails" and no_greylisting.

I have the correct username, password, and port and verified by manually connecting.

By "hangs on this" I mean that I added code to print something before and after that command and the one after never printed anything.

I've tried to run it with debug turned on but it looks like something I did after this messed things up as it fails to connect now instead of hanging:

[root@clarke tools]# python migrate_cluebringer_greylisting.py
* Backend: mysql
* Migrate global greylisting setting.
    - Query enabled global greylisting setting.

But manually connecting still works:

[root@clarke tools]# mysql -u cluebringer -p --port=10031

Bye

I had gone ahead after this with the rest of the steps as I needed to get my email server runnng again and figured that I should still be able to pull the values out of the database since I didn't remove it.

10031 is the port listed in the cluebringer config file and I have it in migrate_cluebringer_greylisting.py.  I'm definitely connecting to the cluebringer database:
