Hi there,

I'm trying to configure and test the BOINC server and client both on my local laptop (Debian 10).

I was able to:

• follow the steps in this documentation and configured the server, apache and MariaDB:
  https://boinc.berkeley.edu/trac/wiki/ServerIntro
  https://boinc.berkeley.edu/trac/wiki/MakeProject
  
• log in to the project web interface successfully
  
• install the boincmgr locally (on the same machine where the server is running).
  
• add the project to the boinc manager gui using http://debian.debian/cplan URL.
  

However, the project files are not being downloaded, and I can see the following in /var/etc/syslog:

I don't understand why the the hostname can't be resolved, because it is defined in /etc/hosts (127.0.01) and I can ping it successfully:

Have you a firewall that’s blocking Boinc?

No, there is no firewall, and besides, everything is local on one machine.

Resolved - the hostname was misspelled in app_versions table in back-end.
