My computer at work connects to the Internet through a proxy server.
BOINC manager doesn't let me set the proxy: when I click on Tools / Options / HTTP Proxy, the "Connect through HTTP Proxy" option is grayed out.

BOINC manager doesn't let me set the proxy: when I click on Tools / Options / HTTP Proxy, the "Connect through HTTP Proxy" option is grayed out.

Tick the 'Connect via HTTP proxy server' Box in the top left corner to ungrey the options.

It's precisely the 'Connect via HTTP proxy server' box that's grayed out. I can't click on it, or modify the options below.

I understand the need to provide as much information as possible when asking for help, but there really isn't much more to it. My BOINC manager can't connect to the Internet because I'm behind a proxy, and the proxy settings are grayed out and so impossible to change.

If it helps, I'm running OpenSuSe 13.2, and I installed BOINC through OpenSuSe's package manager. When I try to set the proxy at the console, I get:

user@linux-gd4s:~> boinccmd --set_proxy_settings
can't connect to local host

Please let me know if there's any additional information that I may provide in order to solve this. Thanks in advance!

This sounds as if the BOINC Core Client isn't running (I've just tried shutting down a Windows client but leaving the Manager running - the 'Connect via HTTP proxy server' checkbox is disabled in Windows too under those circumstances, but is available once the manager has connected to a running client).

Neither BOINC Manager nor boinccmd sets the proxy server configuration directly - they simply pass a message to tell the client to adjust the configuration files. The message is passed via TCP/IP, but to localhost, so shouldn't require the internet proxy to be active in advance.

Here's what I get running boinc-client from the console:
