Howdy Folks,



I have just released an update to the 5.4 line. McAfee
released a new version of their security suite which introduces 'proxy'
server monitors all network communication which includes the
communication between the manager and the core client.



McAfee's proxy server was automatically returning a
successful connection to the core client even though it had not yet
attempted to establish a connection to the core client. This caused the
manager to believe that the core client was already running and so it
did not attempt to launch the core client.



We now attempt to retrieve the screensaver mode from the
core client upon a successful connection which forces the McAfee proxy
to actually attempt to connect and get the data and return back any
error codes that would have normally been returned via connect.



Please have anybody who is experiencing a BOINC Manager
connection failure to update to 5.4.11 as soon as possible. Who knows
how many other security suites will be introducing this kind of feature.
It is my guess they are looking for credit card numbers or social
security numbers to warn of possible identity theft.



Thanks in advance.

Note, it is ONLY for WINDOWS users, MacOS and Linux are still at 5.4.9

Also note the new download layout, you'll only see what your browser reports your OS as (though if you block such information, or don't use a MacOS, Linux or Windows I don't know what you get ;-))

Report any problems to the BOINC developers since it is a newely implented feature.
