Jeremy,
If anything, the 9.1 install (with Python2.3) should be less of a
problem since it includes a fixed version (currently only available in
CVS) of the pyOpenSSL_AG package.
I've noticed that a service will sometimes continue to run even its
authorisation initialisation fails. For instance when VenueClient starts
for the first time & makes a certificate request, you can choose to keep
running without a certificate. The AGServiceManager is similar. I'm not
sure about the VenueServer, but running it without a certificate might
explain your problem.
For me, certificates are pretty much in the realm of black magic at the
moment, so my specific strategy when in a certificate mess is to
completely blow away the .AccessGrid directory. Then reboot (perhaps
grid-proxy-destroy is enough) to remove any residual (and possibly
weird) authorisation. Now if you have a Globus CA, run grid-proxy-init
_before_ running any services. If you have an AG Developers CA, then
you'll have to run the VenueClient and import the certificate (again,
_before_ running any services). When your certificates/authorisations
are active (test with grid-proxy-info), start your services.
On another tack, are you still able to connect to other servers? We have
2 that you can try: the one you probably know at
https://vv2.ap-accessgrid.org:8000/Venues/default still runs the server
from the Slack 9.0 release. I am still testing the server for the 9.1
release before unleashing it online. You can try that new server at
http://exp.vislab.usyd.edu.au:8000/Venues/default.
Also, can other clients connect to your server? I'll try connecting to
it if you can give me its address.
