Greetings...

I've tried my best to find a solution using your FAQs, forums, and Google, but I'm stumped. I have BOINC installed on a couple dozen clients (mis of Windows and Linux), and they're all working fine so the problem appears limited to my new (to me) Power Intellistation. I've got RHEL 5.1 installed and working fine; networking has been fine; no proxy is in place. The BOINC client (version 5.10.17_11 from http://www.dotsch.de/boinc/BOINC%20Clients.html) will start and run benchmarks, but then crap out trying to access the reference site.

I've got BOINC installed in /opt/boinc, with a separate boinc user that owns the dir. I've tried running as the boinc user as well as root.

Here's the command I'm using:
./boinc_client -attach_project http://www.worldcommunitygrid.org <my_account_key_inserted_here>

Here are the results:

I've cleared the firewall to see if that was the problem, to no avail. Does anyone have any suggestions? I'm hoping that I've just been buried in the details trying to fix it that I've missed something big and obvious that someone can point out.

Thanks in advance.
