Hi All,

I have installed the BOINC server on a physical Ubuntu machine using the server_stable code and also tried using the Amazon EC2 instance (http://boinc.berkeley.edu/trac/wiki/CloudServer) but, having the same issue in both cases.

In both cases my Upload/Download server shows as "Disabled". Clients can connect to the project but go in a continuous loop of "Deferred Communication"
All other daemons are "Running" successfully.
I am using the test-app project in both cases.

Any help will be much appreciated.

I had the same issue. Clients were able to process tasks, but the server status page always showed the Upload/Download Server as disabled. I found that /home/boincadm/projects/test/html/user/server_status.php was checking /home/boincadm/projects/test/config.xml for the path to the apache pid (process id) file, and then using a default if a config value wasn't found. There was no value in the config file for <uldl_pid>, so it was using the default of "/etc/httpd/run/httpd.pid" in the server_status.php file. This file doesn't exist, so the U/D Server was flagged as disabled.

I modified config.xml to add <uldl_pid>/var/run/apache2.pid</uldl_pid> under the <config> node, and after fighting my browser cache, the server status page displayed correctly.

I don't remember all the questions, but my guess is that one of the steps in the Test project quick start (http://boinc.berkeley.edu/trac/wiki/QuickStart) probably lets the user set the path to the pid file instead of having to manually edit the config.xml file.
