Cannot connect to localhost (boinc-client not installed)

[Rickster]

When BOINC 5.4.9 is downloaded and installed via Dapper's Applications|Add/Remove utility and one attempts to connect to a computer, the message "BOINC Manager is not able to connect to a BOINC client. Would you like to try to connect again?" is received.

This was repeatable after uninstalling and reinstalling. Also could not connect to 127.0.0.1 or 127.0.1.1 .

I am the only user of this machine and am logged using the only PW established. This situation has been encountered by numerous others and the few suggested resolutiuons set forth have been trtied w/o success (although it would seem that no "work-arounds" or teminal editing should be required.

Side note: The BOINC client runs fine under WIn XP. (I have 6 such clients running and have never had a problem connecting to localhost.)

My assumption is that there is a bug in the BOINC installer or code. Whaddyathink?

I face the same situation. UBUNTU 6.10, german version.

Additional remarks:
The installer (synaptic? gdebi?) installs BOINC 5.4.11, but as can be clearly seen from the BOINC download-page this version is created for Windows!
The recommanded version for Unix-systems ist 5.4.9.

Furthermore: Installing manually 5.4.9, following the instructions given at the BOINC download page, resulted in a running BOINC manager and client. From this I know that there should be also a client-file with the simple name 'boinc' in the installation directory. Searching with "Orte > Nach Dateien suchen" ("filemanager" called in Windows) for the boinc-file in "Dateisystem" (I hope you can guess the proper english term, maybe "filesystem"), there is no such file, only a boincmgr in /user/bin is present.

Hope this helps:
a) UBUNTU 6.10 probably installs wrong BOINC-version 5.4.11. instead of 5.4.9
b) (and maybe as a result of a) no boinc (client) programm available, to which boincmgr could connect.

That is not the case. Your problem is that you only have the boinc-manager
package installed and not boinc-client. Since the BOINC Manager is able to
monitor remote hosts, it is not needed that the BOINC client runs on the same
host as the BOINC Manager, and therefore the boinc-manager package does not
depend on the boinc-client package.

Thanks for the reply Frank.

However: In
Anwendungen > Hinzufügen/Entfernen
and searching for BOINC only BOINC Mgr and KBOINCSpy is offered. (BTW: In Windows mgr AND client get installed at the same time, and so does the manual installation of 5.4.9 in UBUNTU).

http://boinc.berkeley.edu/download_all.php offers no separate client.
How can I install the client in addition with "Anwendungen > Hinzufügen/Entfernen"?

This is drawback in the "Add/Remove Applications" program. It apparently only
lists programs that have a *.desktop file. Use the Synaptic package manager
("System -> Administration -> Synaptic Package Manager") to search for BOINC
and to install the boinc-client package.

It is a feature that both are seperated in Debian/Ubuntu. Think of servers
that don't have X.org.

Hi Frank,
thanks again. I followed your instructions, now BOINC is running.

And that means that the project does not support graphics output under Linux
or that the task is currently not running. If the graphics button is active
make sure that the application is allowed to access the X display by running:

  xhost +local:

See the paragraph about graphics on http://wiki.debian.org/BOINC for more
details.

[Gerhard Klünger (g-kluenger)]

BOINC client IS running.
xhost +local: returns with
"non-network local connections being added to access control list"
No change at all, even after reboot.

Following advice in indicated http://wiki.debian.org/BOINC
I found in
/var/lib/boinc-client/slots/0stderr.txt:

I can't help your here either, since this error is specific to the project
this task belongs to. The best advice I can give you is to ask on the
project's message board about this problem.

I put the problem to the BOINC Manger Message-board,
http://boinc.berkeley.edu/dev/forum_thread.php?id=1308
but until now no solution. I get the impression that project-grafics that work with windows not necessarily work with linux.

[Gerhard Klünger (g-kluenger)]

Problem partially solved, see
http://boinc.berkeley.edu/dev/forum_thread.php?id=1308

a) BOINC Rosetta has no grafics
b) the msgs in /var/lib/boinc-client/slots/0stderr.txt are rather of interest for developers
c) Version 5.4.11 for Ubuntu is a special compilation for Ubuntu 6.10 from a sourcecode very close to that one for Windows, so it got also the version-nr 5.4.11, but in fact the binaries are completely different from that one for Windows systems.

Do you have the same problem with the current Gutsy version (5.10.8-1) ?

[Daniel Hahler (blueyed)]

Marco, if you would have read all the comments, you would have noticed that there are several problems and all appear to be solved, especially the initial problem (by installing boinc-client).
So I'm marking it as invalid (especially since boinc-manager recommends boinc-client, at least in Hardy).

Regarding the "graphics do not display", please refer to bug 72192.

Thank you.
