LAN Analyzer

LAN Analyzer allows you to scan your local network you are connected to via WiFi.

It shows any device answering to Ping requests listing their name, IP address, MAC address

and registered network interface vendor information.

History disabled

- green dot: had already been seen in the network before

                    and answered to ping in recent scan.

- grey dot:   device had beed seen scanning the network

                    in the past but is currently not active

                    or not answering to pings anymore

- blue dot:   device answered the ping and is new to

                   the network

Ping

The Ping utility implements a ping application the iPhone way. Each ping session is being displayed logically grouped and each group is named after the ping destination.

Each received Ping answer is being represented with table entries in the following clearly laid out way:

An entry shows

- from whom the reply was received

- the round trip time (RTT)

- the sequence number of the packet (Seq)

- the time to life (TTL) of the packet

A ping session can be stopped at any time by pressing the Pause button.

When a ping is being started a predefined number of ping packets are being send to the destination host. Each second one ping packet is being send. 2/4 in the Ping icon mean that ping 2 of 4 has been send.

If all pings have being send out the number changes into a (T) indicating that the application waits for the predefined timeout period for incoming ping answers. If all packages have been received before the time out is over the ping session finishes. The Stop button transfers into a start button again ready fort he next session to start. If a session has finished a summary entry is being added:

A summary entry displays:

- the minimum round trip time (Min RTT)

- the average round trip time (Average RTT)

- the maximum round trip time (Max RTT)

- number of packages being send (Send)

- number of packages no answer has been received (Lost)

- Percentage of answers received (Percentage)

During the entire time the application runs incoming ping answer packages are being accepted. Thus pings can be received after the predefined ping timeout. Pings which are being received with a Round trip time higher than the timeout value are marked with a red round trip time (RTT) value.

The number of pings being send can be configured in the applications preferences. As well as the timeout parameter.

History

Each ping session started will be added to the display thus creating a history. When you want to clear the history just touch the trash can button. It is only enabled if no ping session is running.

Super Bookmark

If no destination was entered and the „start“ (Play) button is being hit a so called super bookmark is being used. This super bookmark can be configured in the settings section.

Bookmarks

Just touch as the bookmarks icon to keep track of all your your hosts.

To add new hosts just touch the "+ Edit" button and touch the (+) icon in the appropriate section you want to add one.

Here you can also re-arrange the order of your bookmarks. Existing bookmarks can directly be accessed using the

disclosure button.

For example:

  192.168.1.1-254

  192.168.1.21-42

  10.20.30.40-50

Monitor

The Monitor tool allows you to monitor important hosts. It shows you whether a host is up and down and how fast it replies.

Furthermore it keeps a history of the summaries. We monitoring is stopped you can scroll through this list and see when a host went down and when it was up again. The history can also be emailed.

To monitor your hosts just select your desired group of  host from your bookmark section. The interval in which pings are send to the host can be adjusted on the fly.

 Afterwards you can select it and start monitoring from your apple watch.

This notification shows that 2 devices went up and 1 down.

Please note that the iPhone application must be running in the background to being able to receive notifications on your Apple Watch. The easiest way is to put the iPhone application in the background afterwards starting the monitoring session directly from you Apple Watch

Port Scanner

The Port Scanning tool allows you to secure your network by scanning for example servers or important devices for any open ports.

You can scan any desired port range, use predefines port presets or create your own presets.

Presets can consists of

- single ports

- port ranges (e.g. 1-1024)

-  comma separated port lists (e.g. 21,23,80)

    list may include port ranges (e.g. 20-23,80)

Timeout can be adjusted to your needs for faster scanning. But be aware to shore timeouts may result in incorrect scan results. You should test what timeout values suits your own network needs.

Please note: when changing on the fly settings or entering new port entries the new input is accepted by hitting return button only.

Trace route

Traceroute determines the path to a destionation (if not prohibited by firewalls). Is has been impelemented for very fast (full version) path determination. And it automatically performs reverse lookups on any IP address in the path for better readablility and visualization.

When a trace is running two numbers are being displayed

The first number describes the hop that is actually being traced. And the second number (1-3) the ping which is being send to that hop. For each hop 3 pings are being send with the appropriate TTL.

The green dot indicates that the

target host answered.
