Hi !

I use BOINC 7.2.33 x64 on Ubuntu LTS 12.04.

My institution filters outgoing internet connection through a proxy. I tried to configure the proxy settings using BOINC Manager, going to Tools -> Options -> Proxy HTTP. I checked the "Connect using a HTTP proxy server" box, entered server address and port and my institutional login and password. But this doesn't work, BOINC can't reach the internet.
If I set no proxy settings in BOINC but instead open a terminal and export the http_proxy environment variable, then start BOINC from the same terminal, everything works fine.

Does anyone have an idea why BOINC behaves this way ? I am happy though I could find a workaround and use BOINC anyway.

Thanks in advance,
Mathieu

Does your institution allow something like BOINC? Best ask them for permission first.

Then you'll want to check http://boinc.berkeley.edu/wiki/Client_configuration, more specifically the <force_auth>auth_method</force_auth> option.
You can also set up your proxy through here, with the <proxy_info> option.

---

Could you enable <http_debug> and <proxy_debug> log flags. See Client configuration.

Also, I hear some proxies work with HTTP 1.0. You can force BOINC to use that with <http_1_0> option.

The cc_config.xml file was not present ; settings were stored in client_state.xml.
So, if I create cc_config.xml, add proxy settings and enable http and proxy debug, I get the following :

For me, it's got no obvious meaning ...

Did you try the <force_auth> option? I'm guessing that it's the gss-negotiate that's failing here so something other than that.

You didn't say if you tried with <http_1_0>?

Wow ! You're good, adding this line to cc_config.xml solved the problem :

<force_auth>basic</force_auth>

You didn't say if you tried with <http_1_0>?

I didn't, because of that line :

[http] [ID#1] Received header from server: HTTP/1.1 100 Continue

Thanks very much !
