I've posted the following yesterday in the dev mailinglist, but perhaps
it fits in better here.
I installed sge6.1u6 on an Ubuntu host lately. Using the commandline
interface everything works fine. I've installed the sge_master and the
sge_execd on the same host.
Now I wanted to include the DRMAA in a Python project I'm working on,
but I can't get the python-drmaa to connect to the qmaster. To use the
I've downloaded the newest source from the DRMAA page and installed it
with the usual build/install routine.
Here's the code I'm using (it's pretty much the same as in the

raise _ERRORS[code-1]("code %s: %s" % (code, error_buffer.value))
drmaa.errors.DrmCommunicationException: code 2: unable to send
message to qmaster using port 6444 on host "ubuntu": got send error

I've also checked the port:

nmap says it's open, as well (x-ed out my IP here):

Am I missing something here? Does anybody have a clue, what might be the
