Spurious error messages from Norton Personal Firewall
We have received problem reports from SETI@home users
running Norton Personal Firewall (NPF).
NPF checks outgoing HTTP requests for character strings,
such as parts of your credit card numbers.
SETI@home uses HTTP to download work units and upload results.
Each result consists of about 5,000 characters, mostly numbers.
Any short sequence of digits occurs occasionally in result files.
-
If you have configured NPF to check for several 4-digit sequences,
there is significant chance that at least one of these
sequences will randomly occur in a result file.
NPF will then tell you that SETI@home is
uploading one of your credit card numbers.
This is not the case.
We recommend that SETI@home users configure NPF
to check for longer digit sequences (8-12 digits).
This will greatly reduce the incidence of
spurious error messages.
