perfSONAR User Q&A and Other Discussion

[John Simpkins <>]

Adding to the thread, I'm finding that attempts to patch the CentOS 6 box that upgraded from 3.5 to 4.0RC1 are met with the following error:

psql: FATAL:  no pg_hba.conf entry for host "[local]", user "postgres", database "postgres", SSL off

warning: %post(pscheduler-test-trace-1.0-0.8.rc1.el6.noarch) scriptlet failed, exit status 2

Anyone else encountered this?

No, it threw this error:

I think that's really just a documentation problem, though; the instructions need to be changed to tell you to run the new script instead.

Now I'm fighting with the machine not wanting to run any regular bandwidth tests; I can get bwctl to work manually, and I can test against it with my 3.5 box, but it won't initiate anything. Oh, and after the most recent reboot it won't allow me to log into the web interface anymore. So I'm going home for the day ;)
