I'm running boinccmd, built from BOINC 7.16.6, on a company server (CentOS 7 Core) as a non-root user (I am responsible for the project, but I am not the admin). When trying to connect to an existing account or attach projects, I get an authentication error. The admin added me to the boinc group, which according to https://boinc.berkeley.edu/forum_thread.php?id=10903 should solve the issue, but it doesn't. I can run simple commands like --version or --get_state without problems, and I have confirmed that the client is up and running, and that my working dir is /var/lib/boinc/. But so far, I cannot get it to perform any tasks. Any ideas what the problem could be?

Which command do you use?

boinccmd --run_benchmarks

boinccmd --project_attach http://worldcommunitygrid.org <my_key>

Try

boinccmd --project_attach http://www.worldcommunitygrid.org/ <your account key>

That is what I did, I forgot to type in the www in my previous post.

Are you using your full account key or the weak account key?
Which directory are you running the command from? Does your BOINC Programs directory have a path into the environment path?

I just tested it for myself, have BOINC Manager open.
Did the command from the BOINC Programs directory (in my case, Windows, C:\Program Files\BOINC)

C:\Program Files\BOINC>boinccmd --project_attach http://www.worldcommunitygrid.org (my-key)

ly you have to also supply the password (the one in /etc/boinc-client/gui_rpc_auth.cfg) so try this (substituting the password).
[pre]
boinccmd --passwd PASSWORD --project_attach http://www.worldcommunitygrid.org (my-key)
[/pre]

I'm using my full account key. I'm on CentOS 7, so I'm running from inside /var/lib/boinc.

There is no password in /etc/boinc-client/gui_rpc_auth.cfg. The owner is root:root though, I'll check if that's the problem.

You can manually add a password into the file, something of your own. Doesn't need to be a whole sentence. No line feed at the end though.

The problem was the ownership of the files, changing it to boinc:boinc did the trick. Thanks everyone for your support!
