Message 21642 - Posted: 5 Dec 2008, 16:07:38 UTC

Hi.

Have BOINC running on an iMac 24" with OSX 10.5.5. Had to restore from a time machine backup. Eversince I get the message that the BOINC manager is unable to connect to the internet.
Uninstall an reinstalling didn´t help. Tried everything in my book.

Any Ideas?

Thanks.

BOINC Manager shouldn't connect to the internet. Can you tell us the correct message, please? Are you sure it doesn't say that BOINC Manager cannot connect to the client?

As that's a problem when you do run BOINC Manager, but the core client didn't start. Or when you didn't allow BOINC Manager and BOINC to communicate to each other through your firewall.

The Message is: Boinc can´t access the Internet-check network connection or proxy configuration.

I performed a clean reinstall and am trying to connect to the project websites.

Sounds like firewall trouble but this came out of nowhere. Leopard also doesn´t allow to open ports individually as is my understanding.

The rest of the programs can connect to the internet just fine. As I said I had to restore from a time machine backup and a couple of programs need to be configured afterwards.

I am getting a similar thing. "BOINC Manager is not able to connect to a BOINC client. Would you like to try to connect again?" any suggestions?

Message 21657 - Posted: 6 Dec 2008, 18:55:48 UTC - in response to Message 21656.  

BOINC consists of multiple parts, in Windows these are:
Boinc.exe, Boincmgr.exe, Bointray.exe, boinccmd.exe and Boinc.scr.

Boinc.exe is the actual client, BOINC Manager is only a graphical user interface, making it easy to handle the client. All these parts of BOINC talk to each other on TCP port 31416. Separately, Boinc.exe talks to the projects on TCP ports 80 and 443.

In case you get the message "BOINC Manager is not able to connect to a BOINC client. Would you like to try to connect again?" either BOINC Manager did start, but the client (boinc.exe) didn't, or you did not allow the separate parts of BOINC to communicate to each other through your firewall.

Allowing both Boinc.exe and Boincmgr.exe through your firewall will fix this problem.

Was it a very old backup? From how long ago, by estimate? Did you use a proxy at the time you made the backup? Can that machine talk to the internet on ports 80 and 443?

I am not running a firewall, and I changed no settings, it just happened after a reboot.

When you check in task manager (or anything alike when not running Windows, you never said), does boinc.exe run? Or only boincmgr.exe?

Which version of BOINC are you using and on which OS (besides Windows)?
When you navigate to your BOINC (Data) directory, then open stderrdae.txt, does it give you (and us) a clue there what happened?
What if you look in Windows Event Viewer?

I am running v 6.2.19 on Vista 64. The text file you are reffering to does not exist on my system.

The BOINC data directory is hidden! So you have to tell windows explorer to show hidden files/directories.

It was a very recent backup, I never used any proxy and yes, the machine can connect via ports 80 and 443. But that can´t be individually controlled under leopard, can it? At least I did not find where to open individual ports within leopards firewall.
