Hi all,

I am trying to set up a BOINC server. I downloaded the BOINC Virtual Machine (running Debian Linux) and set it as the server. I downloaded a standard BOINC client on my Windows machine (the host for the Debian VM).

As a start I have been trying to install the sample wrapper and worker applications. I compiled both apps under Windows and FTP'ed them to the Debian host. Then followed the instructions provided in http://boinc.berkeley.edu/trac/wiki/WrapperApp to the letter.

The problem is, when I attach to the project, the client says "project communication failed" followed by "Scheduler request failed: couldn't resolve host name"

At the beginning I thought this was a network problem, but using a single-job set up seems to enable the client and the server to communicate and the client downloads a program from the server (though it fails to create a process, but that is another story).

My questions are: Is there any other modification that should be done to the server or the client? I noticed that the single-job script adds assimilators and validators to the project. Should there be an assimilator and a validator for the wrapper-worker case too? If so, can I find it anywhere or should I write it myself?

Thanks for any help!

Maybe the problem with IP if you use free VM,because there are some restrictions on setting or getting IP.
Good luck

Thanks for the reply. Yes I am using a free version. I'll look into your suggestion.
