After converting to a new boinc client, Boinc Manager gives me the message "The password you have provided is incorrect, please try again" upon startup.

I have my client and manager on the same machine in the same boinc directory.

I have worked through several posts, bug lists etc, and found that it might have something to do with gui rpc.

So I have experimented with the files gui_rpc_auth.cfg and remote_hosts.cfg, but nothing works, and I'm getting quite frustrated.

What am I doing wrong?

Unless you plan on control BOINC from another computer, don't place a password in gui_rpc_auth.cfg

Likewise all you should need in remote_hosts.cfg is 127.0.0.1 (the loopback address) unless you plan to control BIONC from another computer. You can also use hostnames instead of addresses

The BOINC-Wiki! discusses this in greater detail.

Edit: clarified

Thank you for replying to my question.

I have tried several things including putting 127.0.0.1 in remote_hosts.cfg, with and without having the gui_rpc_auth.cfg file, other hostnames in remote_hosts.cfg, etc., but nothing helps.

I have also updated a bug report on the problem in BoincZilla.

Now I plan to create a brand new BOINC directory with only the needed executables (no xml files and stuff) once my current work units are calculated and sent.

But I still welcome any help and suggestions :)

Update to the above...

It didn't work out to make a new Boinc directory with only the executables didn't help - boincmgr still fails attaching to my running Boinc client.

So I've downloaded boincgui instead. And it works! It's a bit simple, but it works.

Should have thought of that. BOINC Manager can be a pain sometimes :/
Another handy program is KBOINCSpy (don't have the url).

It only shows the correct states with BOINC 3.x clients. It does not work correctly with 4.x clients.

I had this problem also. I run BOINC 5.2.13 on Linux (FC4) as a daemon under the account boinc, per the instructions.

After only an hour of banging my head against the wall, I found this works (YMMV because I didn't debug the application, I just threw guesses at it):

$ su -
[enter root password]
# su boinc
$ cd /var/lib/boinc
$ /usr/local/BOINC/boincmgr

Switching to root first is necessary because the boinc account has no password. Of course, if you installed BOINC in a directory other than /usr/local, change the path in the last command to your installation directory.

It occurs to me that you may not have set the working directory for the BOINC Manager. The newest Manager needs to run from the install dir; otherwise, it can't read the password. Not intuitive, but that's what I needed to do to fix this problem here.
