This is strange. Boinc is running on my Linux machine. I just happened to me watching when it suspended a PAH WU and started a new EAH WU. When it did, A small window appeared with the EAH graphics. Some kind of spinning star map. I dismissed the window and EAH produced the following:

2005-02-09 18:16:18 [Einstein@Home] Result H1_0267.9__0268.0_0.1_T09_Test02_3 exited with zero status but no 'finished' file
2005-02-09 18:16:18 [Einstein@Home] If this happens repeatedly you may need to reset the project.
2005-02-09 18:16:18 [Einstein@Home] Restarting result H1_0267.9__0268.0_0.1_T09_Test02_3 using einstein version 4.76

When the WU restarted the graphics window did not come back. I stopped and restart the core client and the graphics window also did not come back.

Remember, this is on my Linux box, not a Windows box where I believe the graphics is pretty standard.

Anyone know what's going on? Can I get the graphics back (not that I want it, since it wastes cpu cycles better left for crunching, but it would be interesting.) Anyone got a pointer to what the graphics represent (if anything)?

Linux Graphics Just Suddenly Appeared.

I know nothing of Linux, but the "spinning Star" is actually the universe, and it is the Einstein graphic. Look down the threads and you'll learn more about it.

Go here to find out about the graphic.

Thanks. After I made my post I found that.

Charles,

Both the Linux and Mac applications that we are distributing are 'graphics capable'. However most Linux & Mac users don't see the graphics because the BOINC project has not yet done a public distribution of the BOINC manager, which is the tool that sends the 'display graphics' and 'undisplay graphics' commands to the application. We have been using and testing this tool on Linux and Mac for several months. Hopefully the BOINC project will start public distribution of this tool soon. Then Linux and Mac users can watch the graphics too!

Cheers,
Bruce

Thanks for that info. But, I wonder what happened to cause the graphics to appear like that. I'm running Boinc 4.19 on my Linux box and there is no way I know of to make them appear.

Hmmm. Makes me wonder. I know how the rpc connection works so that an external application can talk to the core client. In fact, I use a PHP application written by, I think, the fellow who puts out BoincView. I can control and monitor my boinc installation from any web browser. I'll have to dig into the code for that and the core client to see if I can get it to display graphics, too. Something to do for the weekend!

Yup, it works! From a terminal window I connected to the RPC port using telnet. Then I sent it the command and up popped the EAH graphics. It was running an EAH WU at the time. I quickly added this option to the PHP script I mentioned above. However, by the time I did that it had switched to a PAH WU and that does not have graphic capabilities. Have to wait until it switches back to the EAH WU.

You know it never occured to me that one could just telnet in -- it's a good idea. Could you please post a brief transcript of your telnet session? It sounds like a good debugging technique for some purposes.

Cheers,

OK, here's how it's done. Fire up a terminal window - xterm, konsole, whatever.
What port you use depends on the versions of the core client. 4.19 and earlier use port 31416. The 4.5x, 4.6x (and maybe the recent 4.20?) use a different port 1043. Since I have 4.19, I use port 31416. This is what it looks like:

telnet localhost 31416 --I entered this
Trying 127.0.0.1... --
Connected to localhost. -- System responded with this (3 lines)
Escape character is '^]'. --
--I entered this.
--System responded. Graphics appeared
^] --control right bracket to get telnet prompt
telnet> quit --enter quit to end telnet session
Connection closed.

That was it. You do neet the telnet service enabled on your linux box. Mine was not by default. My router keeps it blocked from the Internet.

Hope this helps.

Thanks!

BTW, this also works on the Mac and even on Windows.

> You do neet the telnet service enabled on your linux box.

Why? The telnet client should work without having a server running on the machine. In this case the boinc client should be the server that is contacted by telnet. Is there a telnet client distributed with any Linux distri that doesn't work without a telnet server?

You're right. I should have realized that. I had enabled telnet a while ago so I could reach my Linux box from another windows box on my home network. Was having some problems at the time and X would hang. (Don't worry, my router does not allow telnet through so you can't get to me from the Internet.)_

While we're talking about the graphics on Linux, I just wanted to report a couple of things.

I read the page on this site describing the graphic and how to make changes to them. As described, I can use the mouse to zoom in and out and to rotate the celestial sphere. However, the other keyboard commands listed do not seem to work.
