Unable to Connect to the core client

Hi

I recently changed my UD software and shifted to BOINC and am just not able to connect to the core client. Anyone can help with osme settings?

Many thanks
Amit

Re: Unable to Connect to the core client

There are two common reasons for this:

1) The core client isn't running. Often, security software prevented BOINC Manager from launching the core client.

2) Communication is blocked. BOINC uses TCP on localhost port 31416 for communication - most firewalls permit this by default, but if you are overly paranoid, it may be blocked. Again, check your security software.

If this doesn't help, then please give us further details so we can diagnose your problem more precisely.

Re: Unable to Connect to the core client

Hi

Thanks for the reply. I have disabled all security software and shut down the firewall. I am still not able to connect to the core client.

Also when I go to Advanced-> Select Computer, I do not see anything in the drop-down.

Re: Unable to Connect to the core client

Okay, let me take you through some troubleshooting steps:

Things I need to know first: what operating system are you using, and what version of BOINC do you have?

A word of caution: never shut down your firewall and security software entirely; it leaves your computer vulnerable.

Re: Unable to Connect to the core client

Thank you. The prevailing opinion around here is that Symantec are a pain in the neck, so we will do our best to help you.

First thing to do is rule out possibility (1). Make sure BOINC Manager is started, then open Task Manager and look at the process tab. Can you find boinc.exe?

Hi

Both boinc.exe and boincmgr.exe are running.

Re: Unable to Connect to the core client

Okay.

Now, can you find the place in your firewall software that logs what is blocked?

I don't use Symantec myself, so I am guiding you blind. However, this similar situation may help you: http://www.derkeiler.com/Newsgroups/comp.security.firewalls/2003-02/2681.html

Re: Unable to Connect to the core client

OK, checked and it is not blocked. It appears under the Allowed list aling with WCG, Boinmgr.exe and Boinccmd.exe.

Re: Unable to Connect to the core client

Can you specify exactly what is allowed?

Are you sure you don't have any other firewall or security software active at the same time?
