2. Introduction
Do you want to know if all your Windows NT Servers are alive and pinging? Do you want to receive a
popup message when one if them is not up and running anymore? Start to use FREEping. It’s all in the
name: FREEping is a free ping utility which will ping all your NT servers (or any other IP address) in
free-definable intervals. FREEping will send you a popup message when one the NT servers doesn’t
respond anymore. FREEping can work in the background , so you can concentrate on other important
work.
Do you also want to know how quick all your NT servers are responding to the ping? Take a look at the
FREEping overview window to view all important statistics.
You may ask yourself now: why is Tools4ever giving away such a valuable utility for free? We have
two reasons:
1.
2.
The mission of Tools4ever is to make life of NT sysadmins easier and save much of your valuable
time. That’s just what FREEping can do for you.
We want you to know that we provide four other NT tools, which can also assist you in having
your NT network up and running and save much time. Here’s a quick overview of our other NT
tools:
• The disk quota management tool SpaceGuard. SpaceGuard is loaded with functionality and
has the best price/performance.
• The user & server management tool Network ServaNT. Network ServaNT integrates User
Manager for Domains, Server Manager, File Manager and the Event Viewer into one userfriendly tool. It also adds some features not included into the Windows NT management tools,
like managing NT Workstations, printing, exporting, ‘drag and drop’ functionality and
configuring multiple objects with just one click of your mouse. You can even integrate your
own scripts and batch files into the GUI of Network ServaNT.
• The user management tool UserManagemeNT. This tool will drastically save the amount of
time you are currently spending on creating users, moving users, deleting users, resetting
passwords, disabling accounts etc. The frontend of UserManagemeNT is so simple, it can
even be used by a trainee. You just has to fill in a few blanks and click on the “OK” button.
The complexity is behind the screens. Customizable scripts will create userids, passwords,
home directories, group memberships and so on.
• The Policy Template Editor. This tool will help you to save valuable time on creating or
customizing Policy Template Files.
Do you want to know more about our NT tools? You can find all the info you need, including

4. Using FREEping
Using FREEping is simple and straightforward. With FREEping you configure a number of TCP/IP
hosts. The FREEping utility will send echo requests (“ping”) to these hosts on repeated intervals. The
response times and other information is displayed in a graphical user-interface. When the hosts become
unavailable, FREEping can send popup messages (Windows NT Server and Workstation only).
When you start FREEping for the first time, the localhost (your machine, IP-address 127.0.0.1) is preconfigured for your convenience. FREEping will display if the localhost is reachable or not.
The different columns in the window show information regarding the response times of each particular
host.
4.1
Adding a host to FREEping
To test if an Internet host is reachable, you must add the host to FREEping. You can add any Internet
host or any other machine or device with a TCP/IP address. To add the host, select menu option Host,
Add…, or press on the Add host button of the FREEping toolbar.
A dialog shows up (see screenshot on the next page). In this dialog, you need to specify the settings for
the new host to add to FREEping. The dialog contains the specification how to reach the host together
with the results of the same host. After adding a new host, the results are empty since there are no
results for a new host. The following section describes the entries of the dialog:
Host
Packet size
Ping timeout
Ping success period
© Tools4ever
The address of the host to add. This can be a DNS name or an address in the
decimal dot notation. Examples of valid addresses are www.tools4ever.com
and 147.109.56.123.
The size in bytes of the data send by FREEping in a single echo request. The
default size is 32 bytes.
The echo request timeout value in seconds. When FREEping sends an echo
request, it starts waiting for a response packet. If a response is not received
within a specific time, FREEping assumes that the remote host did not
respond within this time. A time out event is generated.
For FREEping, a host has one of three possible reachability status values:
1. reachable
2. not reachable

3.
unknown.
When a host is reachable it is very well possible that a single ping fails, but
the next ping is successful. In this case, the host is still reachable but for
some reason a single echo response was not received. It makes sense to
assume that the host is still reachable and the status should not change from
reachable to not reachable. To deal with this situation, the Ping success
period and Ping fail period is introduced. When consecutive pings fails for a
period longer then the Ping fail period, FREEping marks the host as
unreachable.
When an initially unreachable host correctly responses to pings for a period
longer then the Ping success period, FREEping marks the host as reachable.
In between, the status of the host is unknown. So, when a host is reachable
and a ping fails, the status changes to unknown. When all pings fail for a
period longer than the Ping fail period the status becomes unreachable.
After a successful ping is received, the status changes back to unknown.
Ping fail period:
Repeat ping every:
Destination:
Message:
When successful pings are sent and received for a period longer than the
Ping success period, the status changes back to reachable.
See Ping success period for more information.
The number of seconds that must elapse before the next ping echo request is
sent.
The NT address of the user of machine that must receive a popup message,
when the host becomes available. This option is available on Windows NT
Server and Workstation only. If no Destination is specified, no popup
message is sent.
The message sent when an Internet host becomes unreachable. If no
Destination is specified, no popup message is sent.
Press OK to add the host to FREEping. The newly added host is displayed in a single line in the main
window of FREEping. FREEping starts sending echo requests to the host immediately. All echo
requests are sent in background tasks. So you can continue working with FREEping while background
tasks are waiting for responses. You can for instance immediately add another host to FREEping.
Once you have added a host to FREEping, the parameters for this host are stored in the FREEping
configuration file FREEping.ini. Next time you start up FREEping, the host is automatically added.

4.2
Changing the parameters for an Internet host
If you want to change some or all parameter settings of a host, you simply double-click on the host.
You can also select the host and select menu option Host, Edit, or press on the Edit host button of the
FREEping toolbar.
The same dialog as with Add host shows up. This time, also the results are shown in the dialog. See
paragraph 4.4 for more information on the results shown in the dialog. To change specific settings for
the host, simply change the values in the dialog and press the OK button. To discard changes, press the
Cancel button. See section Adding a host to FREEping for more information on the individual
parameters.
Changes made in the parameters of a host are stored in the FREEping configuration file FREEping.ini.
4.3
Deleting a host from FREEping
To delete a host from FREEping, select the host to delete and select menu option Host, Delete or press
the Delete host button of the FREEping toolbar.
The host will be deleted from FREEping. This is also stored in the FREEping configuration file
FREEping.ini.
4.4
Results of FREEping
FREEping shows the results in a single window. For each host, is single line is shown. The line
contains the address of the host name and the ping results for this host. The most important results are
shown in the various columns of the window. If you double-click with the left mouse button on an host,
detailed information for this host, together with all available results, are shown in the Ping data dialog.

The following section describes all of the result parameters:
Status
The current reachability status of the host. This can be either OK, WARNING
or ERROR. If the status is OK, the host is reachable for a period longer then
the specified Ping success rate. If the status is ERROR, the host is not
reachable for a period longer then the Ping fail period. In between, the status
of the host is WARNING. The status corresponds with the color of the flag at
the beginning of each line:
- green flag:
reachable;
- orange/yellow flag:
reachability status not known
- red flag:
not reachable
Current response time The last response time of the host of a successful echo request.
Minimum response time: The minimum response time of all echo requests responses received.
Max. response time:
The maximum response time of all echo requests responses received.
Avg. reponse time:
The average response time of all echo requests reponses received.
Pings sent:
The total number of pings sent, during the current session.
Pings received:
The total number of pings received, during this session.
Pings failed:
The total number of pings that were sent but no response was received
during this session.
Ping success rate:
The ping success rate, calculated as the fraction of received pings of the
number of pings sent.
Error:
A description of the last ping error that occurred with this host. If nothing is
displayed, no error occurred.
From these result parameters, the FREEping window shows the following columns:
1.
2.
3.
4.
5.
6.
7.
8.
Host
Current response time (Delay ms)
Pings sent (Sent)
Ping success rate (% OK)
Minimum response time (Min.resp(ms))
Average response time (Avg.resp(ms))
Maximum response time (Max.resp(ms))
Error
You can sort the hosts in the FREEping window on each of these columns by clicking on the column
header field. The sort direction is reversed after clicking on the same column header field again.

Other options
To reset the results of all host, press the Reset results button in the FREEping toolbar, or select menu
option Host, Reset results. The result parameters of all hosts are changed to the values when the host
was first added.
To exit FREEping, select menu option Host, Exit.
Note: When you exit FREEping, all FREEping tasks must exit before the FREEping application
can terminate. If echo requests are pending, this may take some time. This is because each echo
request is serviced by a separate background task. Do not try to kill the FREEping application
the hard way, although this will work as well. Instead, let it end gracefully.
