How
does the Look 'n' Stop licence work ?
The Look 'n' Stop licence allows
using the software for an unlimited time !
Minor-version upgrades of Look 'n' Stop are free, and are
handled automatically by the application. For example, if you
purchase version 2.06, you will receive
other 2.xx upgrades, if any, for no additional charge.
Look
'n' Stop 2.01 users who purchased their licence 5 years ago
could upgrade to 2.02, 2.03, 2.04, 2.05 and the current 2.06 for
free !
Major-version upgrades of Look 'n' Stop
will (very likely) not be free, but a special upgrade price will
be made available to registered users. So, if you purchase 2.06,
the 3.01 upgrade will not be free, but you will not have to
purchase another license at full price, either.
A major release should obviously provide
very new features. In other words, we will not simply fix a
couple of bugs and release a 3.01.

One of
my software can no more connect to the Internet ?
Check that this software is listed
in the Application Filtering page and that it is authorized
(green point).
If this is true, your software might be blocked by an Internet
Filtering rule. The blocked data are probably listed in the log
page. A right clic on correponding line of the log page allow to
create an authorization rule.

What is an Internet filtering rule ?
Before reading this chapter, you
shall read the Internet
Security FAQ page
An
Internet filtering rule is a filtering procedure that can
authorize or block an inbound or outbound data packet.
Internet filtering relies on an internet filtering
ruleset.
Each Internet Filtering rule has 5 attributes that may or
may not be checked : 
,
,
,
,
.
|
|
The
Rule is ON (active). This options allows you to
temporarily
deactivate a Rule without erasing it. Usually, all
Rules are ON. |
|
|
If
the STOP sign is checked, the Rule blocks all the
data
corresponding to the Rules definition. If it is
unchecked, the data are
authorized. |
|
|
The
Rule will warn you when a data packet corresponding to
the Rule
arrives. It allows you LOOKing
at the data in the Log page. A dialog
window and an audio signal (a .wav file of your
choice) can also be
chosen to appear. It depends on the options you
choose in the
Options tab. It also depends on the
attribute (see below) |
| |
Advanced
mode options |
|
|
If
a data packet matches a Rule's definition, the Rules
after it (from top
to bottom) will not apply. Usually all the Rules
have this option
activated
As this attribute is not the most important
one, it is only displayed if
the Advanced mode is checked in the advanced Options.
|
|
|
This attribute
allows a rule per rule selection of rules for
which a
message box appears when a data packet
matches the rule. The
Message Box check box of the Options tab also has
to be checked if
you want to authorize message boxes at global
level.
As
this attribute is not the most important one, it
is only displayed if
the Advanced mode is checked in the advanced Options.
|
A Look
'n' Stop
Rule is used to filter out some data packets in order to block
them (check the sign)
or authorize them (unheck the sign).
Look
'n' Stop
also allows you observing the data packets meeting the Rule's
definition (check the sign)
or not (uncheck the sign).
For most of you, you will not have to edit rules yourself. The
Look 'n' Stop pre-installed rulesets are fine. You shall load
the EnhancedRuleset.rls ruleset through the Internet Filtering
page for a better security.
If you need specific rules, you can import them from this page.

Application filtering versus
Internet Filtering ?
Look 'n' Stop includes two filtering
levels: Application filtering and Internet Filtering.
Internet filtering is a low level filtering. It applies at modem
or Ethernet board level immediately after data enter your PC or
just before they quit your PC. It is an outbound and inbound
filter.
Application filtering applies at a higher level. It applies to
outbound data sent by applications.
So, outbound filtering applies at
two levels. The data sent by an application authorized by
application filtering must also be authorized by Internet
filtering before being sent to the network.
Using advanced options,
application filtering can be tuned to restrict each application
to transmit on some TCP/UDP ports,
whatever Internet filtering applies.

Application
filtering does not seam to work correctly. What can I do ?
First of all, you shall check that
application filtering is really not working.
Remove one application from the Application Filtering list (Example:
Internet Explorer). Launch this application to access to the
Internet. If Look 'n' Stop does not ask you to authorize this
application, it means that Application Filtering is not working
correctly.
In most cases, this is due to a compatibility issue with an
other software. To solve this issue, download and run this
patch.
http://looknstop.soft4ever.com/Tools/LnSRegPatch.exe
Then restart your computer.

I
can not connect anymore to the Internet?
Some ISP (Internet Service Providers)
use fragmented data packets to open and keep the connection.
Those packets must be authorized by Look 'n' Stop.
To authorize them , import these Internet filtering rules:
club_internet_adsl.rie
Put these rules on top of the list and clic on Apply and Save
buttons.

The
file sharing does not work on my network.
If Norton AntiVirus is setup on your
PC, a Windows error message may warn you that the network can
not be accessed.
You can use this patch to fix this compatibility issue:
http://looknstop.soft4ever.com/Tools/NavRegPatch2.exe
Download and run the patch and then reboot your PC.
In some very few cases, the problem may occur even if you do not
use this antivirus. Try the patch that may solve your problem.
Contact (forum, email) through the support
pages if you still have this issue.

Some ports
are "closed" and not "stealth" in a security
test ?
Many reasons can explain this result.
- The network adapter is not correctly selected. Clic
here to learn how to select the correct network adapter.
- The security test might not be reliable. Here is the most
famous online security tests: ShieldUp (www.grc.com).
- You might run the test through a proxy. In this case, the
proxy is under test, not your PC. Configure your browser with no
proxy.
- You might connect through a router that blocks the test before
it reaches your PC. Read your router's documentation for more
details.
- Your ISP (Internet Service Provider) applies "egress
filtering". In this case, some ports are forbidden by your
ISP. There is no way to solve this issue.
- You might have modified you Internet Filtering rules so that
you authorize too much trafic. Load the Look 'n' Stop enhanced
ruleset.

A driver is not removed after uninstalling (Windows 2000 and
XP)
In very few cases, it may happen that a driver is not
removed after the automatic uninstall. Here is the procedure to
manually remove Look 'n' Stop drivers (Windows
2000 and XP).
1.start
regedit.exe from the Start menu.
2.search for Look 'n inside the registry, you probably find
some in:
SYSTEM\CurrentControlSet001\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\000x
SYSTEM\CurrentControlSet002\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\000x
SYSTEM\CurrentControlSet\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\000x
x depending on your system.
3.remove all the 000x containing Look 'n . Be careful to not
remove the first entries (0001, 0002, 0003...) which are most
of the time used by Windows.
4.if the following key exist: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lnsfw1]
remove it.
5.reboot
6.After the reboot, open the Device Manager and if there are
no Look 'n' Stop driver entries, it's ok Look 'n' Stop drivers
are uninstalled and there is nothing else to do. If not, go to
step 3.
1.start
regedit.exe
2.search for S4E_LNS inside the registry, you probably will
find some in:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\
{ad498944-762f-11d0-8dcb-00c04fc3358c}\##?#ROOT#S4E_LNSDRIVERMP#000x#
{ad498944-762f-11d0-8dcb-00c04fc3358c}
with x = 0, 1 2, ...
3.remove the key ##?#ROOT#S4E_LNSDRIVERMP#000x#{ad498944-762f-11d0-8dcb-00c04fc3358c}
You will not be able to
remove this key. You can let it. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\S4E_LNSDRIVERMP
4.reboot your PC.
Here are recommandations to avoid these problems:
- Installation and uninstall with administrator rights.
- Reboot after uninstallation (even if you are not asked to).
- DO NEVER uninstall and reinstall without rebooting after
uninstalling.
- If you see an "Add device" message box during
installation, answer no to it.
