LHC@home

LHC@home has been consolidated and uses SSL for communication as mentioned in this thread last year.

Some BOINC clients are still connecting to the old lhcathomeclassic.cern.ch/sixtrack address, that will be phased out soon.

If this is the case for you, please re-attach the project to the current LHC@home URL presented in the BOINC manager. (http://lhcathome.cern.ch will redirect your BOINC client to https://lhcathome.cern.ch/lhcathome )

For those who are still running an old BOINC 6 client, please upgrade to BOINC 7.2 or later. (The current BOINC client releases are 7.6.33 or 7.8.)

Many thanks for your contributions to LHC@home!

Some part (possibly most) of us are still connecting to the old address due to account managers. I informed them (GridRepublic is my case) about the LHC URL change even in 2011 (it was another address change, I think). It's taken years for them to correct the project URL, but they've still left something unfinished - despite the correct URL at the GR site, the BOINC client produces an error (something like "you used the wrong URL for this project..."). Actually, they return the old URL in the acct_mgr_reply.xml file.
You can say "abandon that troubling feature!" But like all in our life, account managers have disadvantages and advantages.
Finally, the lack of a business process for the project URL changing is a reason for some clients to use the old address, at least for the majority of those who use an account manager.

Thanks for the heads up. Actually the GRID republic team updated the address to the correct URL some time back. I have sent them a note to ask them to check the xml reply. The BOINC client should also be able to follow a redirect, but will warn from time to time about the URL change.

Tristan from the Grid Republic team has confirmed that the correct XML is returned upon joining LHC@home via GridRepublic. You might have re-attached to lhcathomeclassic manually at some stage, or this is a left-over from the past.
