I have exactly the same problem. I followed the steps suggested in the boinc wiki page:
http://boinc.berkeley.edu/wiki/Insta...OINC_on_Fedora, however it is still not working. According to the above webpage, this "problem" is not actually a problem, instead it is a security thing. it didn't seem to me so. It is really frustrating. One interesting point is that I don't experience this problem in Ubuntu linux.
