Hello, Iam running my client in wide WAN site. There is central proxy and also local proxy in my area (it is squid and it have setup central proxy as parent proxy). I have no local access to DNS in internet only via local proxy - > central proxy. When I set up central proxy everything working fine, but when I set up local proxy, there is this message for seti project Internet access OK - project servers may be temporarily down. But squid log have no error messages. 5.x version of boinc client working fine with local proxy. So could you please help what should I do to run my 6.x boinc clint via local proxy? Thank you in advance.

Which BOINC 6 version is this with?
Can you test with BOINC 6.10.13 (the beta release candidate) if you can reproduce this problem?

And please, make a file called cc_config.xml in your BOINC Data directory (the directory in which you find the client_state.xml file).

Add into it these lines:

<cc_config>
<log_flags>
<proxy_debug>1</proxy_debug>
</log_flags>
</cc_config>

Save the file, then restart BOINC.
Make contact with any project and then post the message log of that contact in this thread, please.

Iam working on 6.4.5. or 6.6.31 version

and there is log in case setting up local proxy (ip proxy is changed on xxx.xx.xx.x)

Ok, BOINC 6.10 has a better proxy check. So I will ask again: Can you test with BOINC 6.10.13 (the beta release candidate) if you can reproduce this problem?

---

this was log from 6.10.13 beta version

OK, you didn't say that...

I'll forward it to the developers, ask them for help on this.

---

Request from the developers: Can you turn on the <http_debug> flag in cc_config.xml as well?

Your cc_config.xml will then look like this:

<cc_config>
<log_flags>
<proxy_debug>1</proxy_debug>
<http_debug>1</http_debug>
</log_flags>
</cc_config>

Can you then restart BOINC, make another contact and post a new log, please?
The log will then show a couple of IP addresses of the project you are trying to reach. Just leave them in.

---

of course no problem here it is

Thank you. Forwarded to the developers.

New request from the developers. Add the <http_1_0> option.

Your cc_config.xml file should then look like this:

<cc_config>
<log_flags>
<proxy_debug>1</proxy_debug>
<http_debug>1</http_debug>
</log_flags>
<options>
<http_1_0>1</http_1_0>
</options>
</cc_config>

Save the file, restart BOINC, make contact and please post the resulting log. :-)

P.S: Seti is having their weekly Tuesday outage at this moment, so their servers are down. I hope you can use a different project to check on.

wow! it seems that working now!

OK. :-)

Now, to keep that working like that, but without the extra debug messages filling up your log, change the cc_config.xml file to look like this:

<cc_config>
<options>
<http_1_0>1</http_1_0>
</options>
</cc_config>

Save file, open BOINC Manager->Advanced view->Advanced->Read config file.
Nothing more needed.

As to why this works, here's what Rom said about it:

This implies something happened between the first proxy server and the second. IIRC BOINC 5.x defaulted to HTTP 1.0 connections and the 6.x defaults to HTTP 1.1. By enabling that flag curl will avoid some of the advanced features 1.1 offers and use a more basic connection type.
