I'm running Boinc 6.10.17 on Ubuntu (recently upgraded to 10.04 but I think this problem was occuring before on 9.10 as well). Basically I can't communicate with WCG at all, I have two jobs ready to upload and can't download any more:

I can't even reach the WCG homepage in my webbrowser (Firefox 3.6.3). Any ideas what's wrong/how to fix it?

I'm glad everything is working for you but unfortunately not so here. You say that you had to add a line to cc_config.xml - given that I upgraded from 9.10 I don't think I have downloaded any new WCG jobs, just finished ones that I had before so perhaps this could be the problem? What did you have to add, bearing in mind this is just 32bit not 64 bit like you.

Also, as I mentioned, the problem seems to stem a little deeper as I can't access the wcg homepage (or forums...) from here. Any ideas?

I just used the link from "Choose projects" on the front page of this site, and WCG's front page loaded without delay, using Firefox, from Australia.

Well it definitely seems like the problem is at my end, and there are definitely problems. I tried each of the links in your message and all time out, and when pinging the IPs I don't get anything useful:

That then continues with * * *

I've applied all updates available, and rebooted both my computer and the wireless router. I'm suspicious that I've only noticed a problem with WCG and not with any other projects/websites. Could it be a problem with O2 broadband or am I don't something wrong?

Hi

I'm getting the error messages below. Just on WCG, I can access climateprdeiction.net.

Also, I can't access the WCG Website at all - are there some problems? I've been trying all weekend

Perhaps the DNS servers are not the problem: I've just changed them to the google ones by following these instructions http://www.o2help.co.uk/router-change-dns/ but the traceroute is still the save as posted above and I still cannot access the website/boinc can't access the servers.

Rob is referring to this story: DNSSEC Rollout May 5th 2010.

WhiskyChris,

Were you able to use the IP addresses that Sekerob posted about to access the site? For example, you can add these three lines to your /etc/hosts file on ubuntu.

sudo vi /etc/hosts

198.20.8.246 www.worldcommunitygrid.org
192.20.8.246 secure.worldcommunitygrid.org
192.20.8.241 grid.worldcommunitygrid.org

I've just run traceroute on those new IPs. They go further than the original ones but I'm not sure if they go far enough? Both IPs go the same direction, this is what I get:

Chris,

Can you go ahead and send an email to support@worldcommunitygrid.org and ask for Kevin Reed. In that email can you put in your public IP address? I need to search our webserver log files and see if we even see your requests reaching our servers.

thanks,
Kevin

I found a temporary resolution which may end up having fixed it. I connected to
the Edinburgh University VPN and from there I managed to reach the WCG website and boinc managed to upload finished jobs and download new ones.

Furthermore, having now disconnecting from the VPN I can still access the website and boinc still seems to be communicating happily. Strange, but good? I'll update you if it stops working again.

Thanks for all your ideas,
Chris

... boinc still seems to be communicating ...

Is that without re-booting?

Chris,

Can you attempt to access the website without going through your VPN. We engaged the support team for the bell.ca network and one user we were working with has reported success getting through in the past 12 hours. I want to confirm that your problem has been resolved as well. If you are still having issues can you provide a tracert with and without your VPN turned on?

Also - if you are still offline, please send an email to support@worldcommunitygrid.org because we would really like to get to the bottom of this issue.

thanks,
Kevin

To confirm, the situation now seems to be completely resolved. BOINC is communicating fine, and I can access the website with no difficulties. Thanks again for all your help.

I am having problems setting up BOINC since moving to ubuntu 10.04. I can access the sites via Firefox but not when I try an access application manager from a boinc startup.

I had to change some Firefix settings to get it to work.

Also disable ipv6 in thunderbird.

Also I think I managed to turn off ipv6 least it says disable when I check the ethernet details.

Found some stuff related to IPv6 in /etc/hosts. Took a backup and then deleted the IpV6 stuff. Seems to have solved the problem.
