I try connect from windows and from UBNT but same result :-( event log and config are below. Many thanks event log from boinc-manager: 10/02/2013 12:42:58 | gplan | Sending scheduler request: To fetch work. 10/02/2013 12:42:58 | gplan | Requesting new tasks for CPU 10/02/2013 12:42:59 | gplan | Scheduler request failed: Couldn't resolve host name 10/02/2013 12:43:05 | | Project communication failed: attempting access to reference site 10/02/2013 12:43:06 | | Internet access OK - project servers may be temporarily down. config.xml of the project: <?xml version="1.0" ?> <boinc> <config> <upload_dir> /home/boincadm/projects/gplan/upload </upload_dir> <send_result_abort> 1 </send_result_abort> <long_name> gplan </long_name> <cgi_url> http://192.168.0.12/gplan_cgi/ </cgi_url> <sched_debug_level> 3 </sched_debug_level> <upload_url> http://192.168.0.12/gplan_cgi/file_upload_handler </upload_url> <disable_account_creation> 0 </disable_account_creation> <uldl_dir_fanout> 1024 </uldl_dir_fanout> <download_url> http://192.168.0.12/gplan/download </download_url> <db_user> boincadm </db_user> <log_dir> /home/boincadm/projects/gplan/log_debian6 </log_dir> <app_dir> /home/boincadm/projects/gplan/apps </app_dir> <download_dir> /home/boincadm/projects/gplan/download </download_dir> <fuh_debug_level> 3 </fuh_debug_level> <master_url> http://192.168.0.12/gplan/ </master_url> <host> debian6 </host> <db_name> gplan </db_name> <shmem_key> 0x11112d4c </shmem_key> <show_results> 1 </show_results> <key_dir> /home/boincadm/projects/gplan/keys/ </key_dir> <dont_generate_upload_certificates> 1 </dont_generate_upload_certificates> <ignore_upload_certificates> 1 </ignore_upload_certificates> <db_passwd> </db_passwd> <min_sendwork_interval> 6 </min_sendwork_interval> <db_host> </db_host> <daily_result_quota> 500 </daily_result_quota> <one_result_per_user_per_wu> 0 </one_result_per_user_per_wu> <max_wus_to_send> 50 </max_wus_to_send> </config> <tasks> <task> <cmd> antique_file_deleter -d 2 </cmd> <period> 24 hours </period> <disabled> 0 </disabled> <output> antique_file_deleter.out </output> </task> <task> <cmd> db_dump -d 2 --dump_spec ../db_dump_spec.xml </cmd> <period> 24 hours </period> <disabled> 1 </disabled> <output> db_dump.out </output> </task> <task> <cmd> run_in_ops ./update_uotd.php </cmd> <period> 1 days </period> <disabled> 1 </disabled> <output> update_uotd.out </output> </task> <task> <cmd> run_in_ops ./update_forum_activities.php </cmd> <period> 1 hour </period> <disabled> 1 </disabled> <output> update_forum_activities.out </output> </task> <task> <cmd> update_stats </cmd> <period> 1 days </period> <disabled> 0 </disabled> <output> update_stats.out </output> </task> <task> <cmd> run_in_ops ./update_profile_pages.php </cmd> <period> 24 hours </period> <disabled> 1 </disabled> <output> update_profile_pages.out </output> </task> <task> <cmd> run_in_ops ./team_import.php </cmd> <period> 24 hours </period> <disabled> 1 </disabled> <output> team_import.out </output> </task> <task> <cmd> run_in_ops ./notify.php </cmd> <period> 24 hours </period> <disabled> 1 </disabled> <output> notify.out </output> </task> </tasks> <daemons> <daemon> <cmd> feeder -d 3 </cmd> </daemon> <daemon> <cmd> transitioner -d 3 </cmd> </daemon> <daemon> <cmd> file_deleter -d 3 </cmd> </daemon> <daemon> <cmd> sample_work_generator -d 3 </cmd> </daemon> <daemon> <cmd> sample_bitwise_validator -d 3 --app example_app </cmd> </daemon> <daemon> <cmd> sample_assimilator -d 3 --app example_app </cmd> </daemon> </daemons> </boinc> |

You're trying to run the client on the same machine that the server runs on. I don't think that's possible. But not sure. So please, follow the advice in this thread. |

192.168.0.12 is a private, non-routable IP address. You don't say anything about two important factors: 1) Whether the Windows/UBNT clients are trying to contact your server by name (I guess so, because BOINC is trying to resolve a hostname in a url) or by IP address. What <scheduler_url> appears in the client_state.xml file of your clients? 2) Whether your test clients are on the same physical 192.168.0.xyz local subnet, or whether they are attempting to connect to the server over a wider intranet or even the public internet. To address (1): if the clients are trying to contact the server by name, you will have to be using a local DNS server on the private network (which the client machines will have to use as their primary DNS server - use a forwarder to resolve external names outside the local scope). To address (2): if you are expecting to allow access to the server beyond the local subnet, you will have to register a public url with the global DNS server network, and configure it to resolve to a public (routeable) IP address on your internet connection. Then, configure your peripheral firewall/router to forward BOINC traffic to your server's private IP address. If you are working within an organisation that has a system administrator / network manager, consult them. |
