Ping Scope for iPhone & iPod Touch

Full Version

Lite Version - Free

 

Ping Scope utlizies UDP ICMP-Echo packets to test reachability and round trip times to IP hosts on local networks or on the Internet. On the Internet, some of the hosts may not appear to be reachable due to filters which will cause packet timeouts and will be reflected in the app output. The app can utlize both WIFI and 3G networks although WIFI is always given preference if a valid connection is available.

Features And Controls

  • Resolved IP Address

    This is the IP Address returned by the DNS server after a successful name resolution.

  • DONE BUTTON

    Pressing this button will save the currently set parameters and return you to main screen.

  • Network Status

    This section displays the currently selected network. The three possible values are:

    - WIFI: Wireless is available and selected. Wireless is always the preferred and will be automatically selected if available.
    - 3G: 3G Cellular data network is available and selected.
    - N/A: Displayed when no active network interfaces could be detected. In this case, the application will only ping localhost (127.0.0.1).

  • Default Button

    The Default button resets all parameters to their default values as follow:

    - Packet Interval: 1 Sec.
    - Time To Live: 64 Hops.
    - Packet Size: 56 Bytes.

    When this app is installed for the first time, all options are set to default values. In most cases, default values are appropriate and should only be changed for challenging troubleshooting scenarios.

  • CONSOLE OUTPUT

    This section provides continuously updating stats on received ICMP packets. In the event a packet is not received the display will indicate a timeout. Any reply other than a valid ICMP-ECHO type will output IP Header parameters in this section.

    This section of the display is also user scrollable during and after the pings for historical reference.

  • PARAMETERS DISPLAY

    This section show the currently set position of the corresponding slider. The displays are updated as the sliders move. The display ranges which correspond to the slider ranges are as follows:

    - Packet Interval: 1 ro 25 secs in increments of 1.
    - Time To Live: 1 to 128 hops in increments of 1.
    - Packet Size: 0 to 200 bytes in increments of 8.

  • PACKETS COUNTS

    This section provide statistics on packet counts and is updated continously during a ping run. The four counts displayed are:

    - XMTD: Number of packets transmitted.
    - RCVD: Number of packets received.
    - LOST: Number of packets lost.
    - DUPS: Number of duplicate packets received.

  • PARAMETERS SLIDERS

    These sliders allow the user to change parameters for precision troubleshooting as follows:

    - Packet Interval: 1 ro 25 secs in increments of 1.
    - Time To Live: 1 to 128 hops in increments of 1.
    - Packet Size: 0 to 200 bytes in increments of 8.

  • PACKETS TIMES

    This section provide statistics on packet times and is updated continously during a ping run. The four values displayed are:

    - MIN RTT: Minimum Round Trip Time.
    - MAX RTT: Maximum Round Trip Time.
    - AVG RTT: Average Round Trip Time.
    - STD DEV: Standard Deviation.



  • CONFIGURABLE PARAMETERS

    This section of the main screen displays parameters values set in the option screen.



  • HOST NAME/IP ADDRESS BOX

    A user can enter a URL, a host name or an IP address in this box to start the ping process.



  • CONTROL BUTTONS

    The three buttons perform as follows:

    - OPTIONS: Takes you to the options screen. This button will only function when there is no ping process running. The parameters in the options screen can only be set when ping is stopped.
    - STOP: Stops the ping process. This button will only be available when an active ping process is running.
    - START: Starts the ping process. This button will only be available when there is no ping process running.
