I switched firewalls not too long ago. Recently, the new firewall has twice alerted on Internet access requests. The second source, similar to the first, is wcg_c4cw_lmps_6.41_windows_x86_64. The destination IP in both cases is 224.0.0.22 (which is reserved for multicast). I don't see any messages in the BOINC client that appear to relate to these alerts.
The wcg_ prefix makes me think to look here. The Computing for Clean Water project uses c4cw_. I do allow this project. Google doesn't seem to have any authoritative references on this process. Do I have a problem? Do others get this firewall alert? Thanks! |

I think this is related to security certificates.
----------------------------------------From a WHOIS resource: http://whois.domaintools.com/224.0.0.22 shows "reserved for multicast" and clicking HOST link reveals assigned to VeriSign. Paul.

What brand FW is this, what release and what's the exact message?
See no association of that IP and WCG. The host does occasionally check the quality of the network connection per help: http://www.worldcommunitygrid.org/help/viewSearch.do?searchString=scan but why that particular IP would be taken as vehicle, techs would have to elucidate. Should anything try to piggy-back in with the WCG workunits, there are checks and encryptions, which would cause the files to be removed as invalid. --//-- |

I'm using ZoneAlarm's freeware firewall. I have since dismissed the alert. It was ZoneAlarm's standard "a program is seeking access to the internet".
Program name: wcg_c4cw_lmps_6.41_windows_x86_64 Destination: 224.0.0.22 The previous incident, maybe 1 month ago, specified program: wcg_c4cw_lmps_6.13_windows_intelx86 Given the defenses built into the WCG workunits, should I assume that one of these is true?
The BOINC client identifies 4 active tasks, one each for projects
The C4CW project report deadline is today. Windows Vista 64-bit shows 5 WCG tasks:

Well, I googled on the combo ZA+224.0.0.22 and there were a bunch of hits, such as this: http://www.tek-tips.com/viewthread.cfm?qid=994892&page=784. It's likely never to get outside of your (W)LAN.
