N-View
Your network at a glance
Tutorial (Version 3.x)
I apologize for my poor English!
All dialogs in N-View are in English only. Nevertheless, when NOT running with Administrator privileges on Windows, some functions depend on the language version of the host operating system (See 1.6 below). Up to now the language versions English, German, Czech, Polish, Dutch, Finnish, Danish, Italian, French, Swedish, Norwegian and Japanese are supported and tested.
N-View is Java based and can be deployed on all Java supporting operating systems. Therefore it needs a Java Runtime Environment (JRE) of version 1.5 or above. Java versions below 1.5 are in the current version of N-View no longer supported! This current JRE can be downloaded for free at http://www.java.com/en/download/manual.jsp for nearly all operating systems. You can also download N-View itself for Linux or Windows each in two versions (with or without JRE). The N-View "with JRE" version installs a JRE for use with N-View only and does not change the Java environment of the operating system it runs on. But it needs much more download capacity (about 20 MB) and more disk space for installation (about 40 MB).
So it is recommended, to check the Java environment of the current operating system before downloading N-View. You can find out, whether You have the required JRE version already installed by typing "java -version" on a command prompt. Check the output, given by the command, for a line containing the version of Your Java environment. In case You are not sure, simply download and install the "with JRE" version.
Since version 3.1 the installation and uninstallation procedure of N-View has changed. Download one of the Linux versions:
These are self extracting archives. You must have "root" privileges to install N-View. Executing the archive will create a subdirectory "N-View-Linux-Installation", then change to this directory and start the script "Install.sh" automatically. The script interactively creates a new directory "/usr/local/NView3x/" and copies all required files there. The script will also copy a link to the N-View start script onto root's desktop. Please copy this link into the "Desktop" directory in all user home directories, who may use N-View. You can also start N-View by calling the script "/usr/local/NView3x/StartNView.sh" in a terminal window. After successful installation the directory "N-View-Linux-Installation" is not longer needed and can be removed.
In case You want to uninstall N-View, simply execute the script "/usr/local/NView3x/UnInstall.sh".
Important note: In case You have an older version (2.x) of N-View installed on Your system, please uninstall it to avoid confusion. You can simply remove the old "/usr/local/NView/" folder and the desktop icon "N-View".
Since version 3.1 the installation and uninstallation procedure of N-View has changed. Download one of the Windows versions:
Start the automatic installation by double clicking this
file and follow the given instructions. On Windows NT or Windows
2000/Xp You need Administrator rights to install N-View.
The installation creates a new directory "\Program Files\NView3x\"
in Your system drive and a program folder "N-View Network Monitor" in Your start menu.
In this program folder You can find a start icon "N-View-3x",
start icons for the German and English version of the Tutorial
and an uninstall icon.
You can start N-View by double clicking the "N-View-3x" icon.
Important note: In case You have an older version (2.x) of N-View installed
on Your system, please uninstall it to avoid confusion. You can simply remove the old
"\Program Files\NView\" folder and the desktop icon "N-View".
Since version 3.1 the installation and uninstallation procedure of N-View has changed. Download one of the Solaris versions:
These are self extracting archives. You must have "root" privileges to install N-View. Executing the archive will create a subdirectory "N-View-Solaris-Installation", then change to this directory and start the script "Install.sh" automatically. The script interactively creates a new directory "/opt/NView3x/" and copies all required files there. The script will also copy a link to the N-View start script onto root's desktop. Please copy this link into the "Desktop" directory in all user home directories, who may use N-View. You can also start N-View by calling the script "/opt/NView3x/StartNView.sh" in a terminal window. After successful installation the directory "N-View-Linux-Installation" is not longer needed and can be removed.
In case You want to uninstall N-View, simply execute the script "/opt/NView3x/UnInstall.sh".
For other operating systems is currently no adapted installation packet available.
In this case please use the packet "NView3x.zip" for the installation.
First download and install a Java runtime (JRE)
prior to the N-View installation.
Then check by invoking the command:
"java -version"
in a command line
whether Java is in the path and it's version is above 1.5. Please also
check whether You have a program "ping" in Your system and You are
permitted to start it.
If this is successful download the file "NView3x.zip" from the N-View download site. Create a new directory in Your system and unpack this file there. To start N-View open a command line, change to this directory and type "java -jar NView3x.jar".
IMPORTANT: For upgrading from N-View version 2.x to 3.x NO update paket exists! In this case You must uninstall the older version and install the new version like mentioned above. Also You should upgrade Your Java Runtime Environment (JRE) to the newest version. The following description is ONLY useful for further upgrading within the main release 3.x of N-View.
In case You have a proper running version of N-View installed and want to upgrade, it's not necessary to download the whole installation. Please download the file "NView-Update.zip" only and extract it into the installation directory of Your N-View, overwriting older files.
N-View is nearly complete pure Java. This has the advantage of running on nearly all important operating systems with a nearly identical "Look&Feel". Because of their OS independence Java programs are restricted to not being able to send or receive ICMP packets (ping) in a network. So N-View has been enhanced by so called "Native Libraries" being used for sending and receiving ICMP packets. The following libraries are available in the current version:
When starting N-View recognizes its host operating system and the processor architecture and looks for an appropriate library. If one could be found, N-View tests whether it is permitted to send and receive ICMP packets. If this test fails or the needed library could not be found a popup dialog giving some hints will be displayed, and using the native "ping" command will be tried. Because of the language dependence of the "ping" command's output no guaranty for its proper operation can be given (see introduction on top of this document).
Therefore it is highly recommended to start N-View with root-/Administrator- privileges. In case there is no native library for Your environment available yet, You can use the source files in the "src" directory to create Your own library. More hints about how to do this can be found in the source files "JPingImp_Unix.c" and "JPingImp_Windows.c".After start-up, N-View opens two windows: A terminal window for debug outputs and error messages and the GUI window. The terminal window maybe minimized in normal operation.
N-View uses the program "ping" of the operating system to send ICMP packets. Please note, that all users need execution access to "ping" for using N-View. In Windows this is by default enabled. In Linux or Unix systems You may need to use "setuid" on "ping".
Start N-View and open the "Network Properties" dialog by choosing
"View | Settings" or clicking the icon
.
First You should give a name to Your network. (field "Main Window
Label").
N-View provides automatic email messages, if a host in Your network fails to respond. Configure at "Smtp server", "Sender (From)", "Recipient (To)", "CC" and "BCC" Your email connection and click "Send Test Message". If Your configuration is correctly, the recipients will get a test email.
N-View will show an icon for each configured subnet in its main window. This icons can be dragged to any position on the screen. You can load any graphic file to be displayed as a background picture of the main window. Check "Enable Background Picture" and choose an image file (*.gif, *.jpg or *.png). You can also test this feature by loading a map file from the N-View program directory.
N-View uses MSIE on Windows or Netscape on Linux for displaying HTML pages. If You want to use another browser, please enable "Custom Command" and fill in the start-command into the text field.
If "Generate HTML Pages" is checked, N-View creates a graphic file "Sub_<n>.gif" for the main window and each subnet window, containing their current screen content. For displaying this information in a browser, additional simple HTML frame pages with links to this pictures are generated. In the field "Destination Path" the destination of these files can be chosen.
N-View provides no HTML server. To enable users in Your network to access this information with their browsers, You should install a HTML server and choose its document root as the destination path for N-View's dynamic pages. It's not important, on which host this HTML server is running in Your network. But You may ensure, N-View has write permissions to the document root of this server.
On the second tab of the "Network Settings" the output of log information can be configured. In the top section has to be chosen, whether log information should be created and where it has to be put out to. In the middle section the events to be logged can be chosen. In the bottom section the fields for output and a field separator are chosen. The field separator character can be chosen from a menu or created as an individual string, containing an arbitrary number of characters.
Log files, created this way, can be imported into any database or table calculator program, using a text file import function there, and can further being computed in any kind.
On the third tab of "Network Settings" you can setup N-View to play sounds, when some events occur. There are several internal soundclips, which can be chosen for each event, listed in the panel. If required, any external soundclip-file (*.wav, *.au, *.mid, *.aiff) can be chosen for each event. Please note: In case of an event, the soundclip is played only once without any chance to stop it. Therefore soundclips with an appropriate length should be chosen.
The chosen sounds are applied to all given events in all subnets and hosts. In the "Subnet Properties" and "Host Properties" for each object can be individually set, whether or not it plays a sound.
On the fourth tab of "Network Settings", advanced settings can be made. Unlike all other settings, these become already effective during program startup before loading a stored network configuration (*.nvw file).
Under "Set Look&Feel to" the appearance of the program can be selected. Which Look&Feels are selectable depends on the operating system and the current Java version. On Windows systems the Look&Feels "Windows", "Metal" and "CDE/Motiv" are available. On Linux systems "Metal", "CDE/Motiv" and off Java version 1.4.2 "GTK+" are selectable. The selected Look&Feel can be tested with "Apply". Please note: Due to a bug in the JRE the background color of text fields is corrupted with GTK+ Look&Feel.
A configuration file to automatically be loaded at program startup can be setup in the next section.
With the "Debug Mode" check box, a verbose debug output to the terminal window can be forced. This setting shall help to fix problems with program startup. This output is subject to be changed to the current requirements in future versions without any announcement. Please use this only for fault localization in cooperation with the N-View support.
The check box "Startup with Fullscreen" forces the program to start always in maximized window mode.
Please click on "Apply Settings to next Startup" for the current settings to take effect at next program startup.
For each monitored subnet N-View displays a subnet window and an icon in
the main window. Create a subnet by choosing "Subnet | New Subnet" or
clicking the
icon on the toolbar. You will get a "Subnet Properties Dialog".
In the "Subnet Properties" dialog You can put in a name for Your subnet in the "Subnet Label" field. You can also choose an icon for Your subnet to be displayed on the main window.
In the Icon Chooser You can find a "Custom" button. Choose arbitrary more icons there. By double clicking this button, a file dialog appears, where any image files in GIF, JPG or PNG format can be chosen. Also "animated GIFs" are possible.
Please choose 3 pictures for the 3 possible states of the subnet or host (green, yellow, red -- see "Signaling" below) and click OK. By one click on the "Custom" button the chosen picture is used as an icon in the display.
This way chosen pictures are displayed in their original size up to a format of 160x120 pixel. Larger pictures are automatically resized to fit this format, while their original aspect ration is kept.
Please note:
Resizing pictures requires significant additional CPU load. If You want to use
many "Custom" icons, it is recommended to resize them with a picture
editor to fit 160x120 pixel, before usage.
Like in the main window, You can display a background picture in any subnet window. Check "Enable Background Picture" and choose an image file (*.gif or *.jpg). You can also test this feature by loading the "Floorplan.gif" file from the N-View program directory.
Now put in an IP address and a subnet mask (number of bits of the network part) of a network that can be reached from Your PC under "Subnet Address / Mask".
N-View discovers hosts in Your subnet by sending ICMP packets (ping) and listening for responses. From "Discovery Timeout" depends, how long N-View waits for a response. If "Resolve Hostnames" is checked, N-View resolves hostnames with a reverse DNS lookup. If no DNS is available at Your network, please uncheck this box, to avoid N-View waiting for DNS timeouts. "Check Interval" means how often host responses will be checked.
In the second tab of the Subnet Properties Dialog ("Host Defaults") you can choose the default settings, that will be predefined to all discovered hosts. "Default Warn Delay" is the response delay after that a host icon will change from "green" to "yellow" and, if enabled, a warn mail will be sent. "Default Timeout" is the maximum delay for a host response. If exceeded the host icon will change to "red" and, if enabled, a fault mail will be sent. "Show Hostname" and "Show IP Address" decide whether the hostname or the IP address of this host is shown below its icon in the subnet display. "Play Sounds" enables a sound playback for this host's events when in the "Network Properties" dialog playing sounds is generally enabled. The "Dynamic IP" box is used to define whether the hostname or the IP address of the new discovered hosts are used for "pinging" them. The "Default Mail Recipient" will be predefined as the recipient for this messages and can be changed in the "Host Properties" dialog. With the check boxes "Signaling", "Auto Hide" and "Auto Remove" these settings will be predefined in the "Host Properties" (see there) of all new discovered hosts. Under SMNP You can setup the default-values "read community" and "write community" for the SMNP-access to hosts.
Now click "Start" (in the "Settings"-tab). You can watch the progress of the scan in the progress bar. In the table You get an entry for each discovered host. By right clicking into the table You can manually add or remove hosts.
In the third tab of the Subnet Properties Dialog ("Remarks") you can achieve an editable text field. An arbitrary text can be registered here. The registered text will appear as popup window next to the subnet icon, when the mouse pointer is positioned over the subnet icon. By deactivating the "Popup on Display..." check box, this automatic popup can be disabled. Under "...after X Seconds" a value between 1 and 10 may be entered, that determines the delay of the popup after positioning the mouse pointer over the icon.
All hosts belonging to that subnet are listed in the hosts table of "Subnet Properties". Here can be manipulated the behavior of host icons individually. With the entry in column "Fault Mail" You can decide, whether or not on timeout a mail message for this host is sent. The column "Signaling" activates or deactivates the change of the subnet icon color, when this host times out. The column "Hidden" decides whether or not a host is displayed in the subnet display. Also "Autohide" and "Autoremove" (See below) can be enabled/disabled in the table.
By checking the box "Auto Arrange Icons", You can arrange all host icons automatically as circle in the subnet window.
Now click "OK". You get a new window for Your subnet with an icon for each discovered host and if chosen a background picture in it. You get also an icon for Your new subnet in the main window.
If You have unchecked "Auto Arrange Icons" in Your "Subnet Properties", host icons can be dragged to any position. Otherwise they are automatically arranged as a circle. By double clicking the subnet icon (in the centre of the subnet window or in the main window) You can get the "Subnet Properties" dialog again.
Click with the right mouse button on any icon, so You will get a context menu. Here You can remove all lines to this icon or draw new lines to other icons. This way You can adapt the subnet-display or the main-window to You real network structure.
By double clicking a host icon, You can get its "Host Properties" dialog.
In the "Host Properties" dialog You can choose a host icon and put in a host label ("Label Text").
With the "Custom" button one can choose arbitrary image files to be used as icons for a host in the same way, like described in the "Subnet" section (see 2.2.1 above).
If You check "Show Hostname" or "Show IP Address" the DNS name or the IP address will be displayed below the hosts icon. The check box "Dynamic IP" decides whether the hostname or the IP address is used to send ICMP requests to this host. If "Dynamic IP" is checked the IP address of this host is resolved by a reverse DNS lookup.
If "Warn Delay" is exceeded, the hosts icon will change to "yellow" and if enabled a warn mail will be sent. If "Timeout" is exceeded, the hosts icon will change to "red" and if enabled a fault mail will be sent.
In the "Last Check" and "Last Seen" fields you can find the date and time, when this host was last time "pinged" and when the last response was received.
Check "Send Mail on Warnings", if You want warn mails to be sent. Check "Send Mail on Timeouts", if You want fault mails to be sent. In the "Email Address" field You can give an individual mail recipient for each host.
Is "Autohide" checked, this host will be set to "hidden", if it doesn't respond for a defined amount of time. This means, it will not be displayed until it responses again. The delay for "Autohide" can be set from 1 minute to 30000 minutes. This should be applied to "unimportant" hosts, that are often down. This way You get a better overview in the subnet display. Displaying of "hidden" Hosts can be enabled/disabled with the check box "Show hidden Hosts" in the Toolbar of N-View.
"Autoremove" removes this host from the subnet display completely after a delay, if it doesn't respond. The delay can be set from 1 hour to 30000 hours.
If a host changes its status (up, down, delayed or reception of a SNMP trap) a action can be taken. In the second tab of the "Host Properties" dialog You can setup email messages or the execution of some external command for those events.
In the third tab of the Host Properties Dialog You can reach a port scanner. It scans the current host for open TCP- and UDP-ports. Choose a range for the port numbers to scan, choose a protocol (TCP and/or UDP) and click "Start".
PLEASE NOTE: Some system admins don't want their hosts to be scanned for open ports! They see it as an attack against their security. So don't be nasty. Scan Your own hosts only!
In case You scan against a host, that is secured by a firewall, the port scanner has to wait for a timeout of some seconds for each protected port. This procedure can take a while!
If You choose "Cyclic Check open Ports", at each "Scan Intervall" (Subnet Properties) all ports, listed in the table, are checked to be still open. If You check "Send Mail on Changes" a mail message to "E-Mail Address" (1st Tab) will be sent on port status changes.
The Column "Signaling" determines, whether a port is included into the port status signaling procedure. This column is editable. When "Signaling" is checked, each status change of this port is reported by mail (when enabled) and a message "Port(s) fail" is shown next to the host icon and the subnet icon, when this port is closed. When "Signaling" is unchecked, the status of this port is ignored in port status signaling.
By right clicking into the table, a context menu is reached. By this menu, ports can be manually included, removed from the table or edited. This way ports can be added, even if they were not open, when portscan was performed, but should be watched in the future. By double clicking a port entry, a "Port Properties" dialog will open. There can be some port properties be changed. Specially the "Service" field can be changed to an individual string this way.
If configured, You can make Telnet- or HTTP connections to hosts directly from N-View. So it's possible to manage network printers, switches, hubs or Linux/Unix machines. The configuration menu for host connections is available on the fourth tab of the "Host Properties" dialog. You can configure, activate and test telnet- and HTTP connections. Also You can choose, which action by double clicking a host icon should be taken. By default, start of the "Host Settings" dialog is checked, so the "Host Properties Dialog" will be started. If You check "Telnet Client", the telnet client with the configured settings will be started by double clicking the host icon. Also You can activate "Http Browser", so the default browser of Your System is started by double clicking the host icon.
Under "Host Connections" also for each host a call to an arbitrary external program can be configured. This way You can configure a SSH connection to that host and start it by double clicking the host icon. Include the full path to the external program (with all necessary arguments) into the field "Command line" and activate "Enable external Command".
If You provide a username and password in the telnet configuration, You will be automatic logged on into the host after connecting per telnet. Please note: Passwords are stored as plain text in N-View configuration files (*.nvw)!
In the fifth tab of the Host Properties Dialog You can get the SNMP client. It provides functions for sending SNMP requests to this host. In the "Community" field must be entered an available community name. If a SNMP agent on the host is running and answering requests, the results are displayed in the "Object Identifier", "Object Type" and "Value" fields. If You click "Description", You can get a description of the chosen Object. Click "Get all" for requesting all available SNMP objects of this host.
The received Mib-2 objects can be selected in the tree structure in the window below. If "Store Object IDs" is checked, this tree structure (not the values) will be saved, when the Host Properties Dialog is closed. On opening this dialog again, the tree structure will be restored. Depending on the number of entries, this can take a very long time. While restoring the tree structure, the OK button and Cancel button are disabled.
If "Receive SNMP Traps" in the N-View main window is checked, SNMP traps from hosts can be received. Check "Popup Trap Messages", if You want to get a popup window on receiving a trap from this host. If You check "Send Mail on Trap Messages", an e-mail message will be sent to the chosen recipient, if a trap message from this host arrives.
Please note: You must be permitted for receiving SNMP traps (listen on UDP port 162) in Your operating system. If this permission is denied, the check box "Receive SNMP Traps" in the N-View toolbar will be disabled. The trap sending host has also to be configured for sending traps to Your N-View host as a trap receiver.
In the sixth tab of the Host Properties Dialog You can set up "Traffic Graphs" for all network interfaces of this host. Please note: This feature requires a SNMP agent running on this host. If You check "Sample traffic for this host" a list of the host's network interfaces will be displayed in the table, provided the host responds to SNMP requests and the "Community" is set properly.
The "Sample interval" can be set from 1 minute to 60 minutes. Because the total number of samples is fixed to 288, the displayed time range (in the graph) can vary between 4 hours 48 minutes (1 minute interval) and 12 days (60 minute interval). The default value of sample interval is 5 minutes. This means, the traffic graph will show 288 samples with the 5 minute average traffic over the last 24 hours.
Each entry in the table represents a network interface of this host. The column "Interface" contains the interface name provided by the SNMP agent. The column "Label" is generated from the first 20 characters of this name and can be arbitrary edited by double clicking into the field and typing an interface name of Your choice (it will be displayed in the traffic graph). Check "Display Traffic Graph" to display a graph for this interface. This graph will be displayed on the Subnet Window. If You want the graph to be displayed on the Main Window instead, check "On main Window" too.
By closing the "Host Properties Dialog" an empty traffic graph will be displayed for each configured interface (vertical arranged on the right edge of the chosen window). You can drag these graph to any position on the screen, left click to zoom in or right click to zoom out.
PLEASE NOTE: The first sample will be displayed after 2 sample intervals. So, if You have configured the sample interval to be 60 minutes, the first sample will be displayed AFTER 2 HOURS.
The traffic is displayed as blue line (for outgoing) and green area (for incoming), linear in bits per second. Incoming and outgoing are defined to be seen from the view of the host the interface belongs to. In case of missing samples (host could not be reached or SNMP agent was down), a vertical red line is displayed for each missing sample.
In the seventh tab of the Host Properties Dialog ("Remarks") you can achieve an editable text field. The functions for input and displaying of this text are analogously to the subnet as described under 2.2.6.
If "Discover new Addresses" is chosen, in each check interval the subnet address range will be scanned for new hosts. If "Check Response" is chosen, only known hosts responses will be checked.
If You want all hosts of a subnet to be removed and new scanned, choose "Delete and Discover New" and click "Start". In normal operation (cyclic scanning), this is identical to "Check Response".
If You want a host not to be displayed, check "Hide This Host" in the "Host Properties". To display this host again, open "Subnet Properties", right click this hosts entry in the table, open its "Host Properties" and uncheck "Hide This Host".
By right clicking a hosts entry in the table ("Subnet Properties") You can get a context menu, witch allows You to remove that host or add a new host.
Text lines for mail messages can be configured in the "Subject" fields in the "Host Properties" dialog.
By menu "Window | Cascade" or clicking at the
icon You can choose the main window and
all subnet windows to be displayed as cascaded windows. The windows can
be moved and resized. By menu "Window | Tabbed" or clicking at the
icon the standard (tabbed windows) will be displayed.
The order of displaying subnets in the "Tabbed View" can be permanently changed by dragging&dropping the tab-headers.
By menu "File | Save" or "File | Save As" or clicking the
or
icon You can save Your
settings in an file. This way saved settings can be restored by menu
"File | Open" or clicking the
icon.
N-View checks host responses cyclic with the "Check Interval" (Subnet
Properties). If a host responds in less than "Warn Delay" time, its
icon will be displayed "green". If "Check Interval" is exceeded, the
icon changes to "yellow". If the host sends no response until
"Timeout", the icon changes to "red". If at least one host has a
timeout, the subnet's icon changes to "yellow". If no hosts of a subnet
sends a response, the subnet's icon changes to "red". If You want a
host to have NO effect (timeout or delay) to subnet status signaling
(colour change of subnet icon), uncheck "Include this Host in Subnet
Signaling" in Host Properties.
In case You have checked "Cyclic Check open Ports" in a hosts port
scanner, the string "PORTS OK" or "PORT(s) FAIL" is displayed beside
the host's and the subnet's icon, depending on the port status.
With menu "File | Print" or clicking the
icon network diagrams can be printed. One
page for each window (main window and subnet windows) is put out on the
chosen printer, in the same view, they are shown on the screen. The
diagrams are scaled and rotated automatically for best fitting the
printed page format. The
results depend on window size, screen resolution and chosen view
(tabbed or cascaded windows) of N-View. Best results can be attained
with maximized N-View on a screen resolution 1024 x 768 with "tabbed"
view.
By choosing "File | Import MIB" or by clicking the
symbol in the toolbar a MIB Parser Dialog can be reached. This can be used to
enhance the OID database of N-View.
In the following Parser Dialog choose some MIB definition file, a directory containing several MIB definition files or a N-View configuration file (*.nvw). After clicking "Import" the OIDs, contained in the chosen file(s) are added to the OID database. When a single MIB file was chosen, only the containing OIDs are imported. But for proper operation of the parser all "IMPORTS" files defined inside the chosen MIB file must be present in the same directory. When a directory was chosen all OIDs of all contained MIB files are imported. But please note: The recursive character of the parser can lead to memory overflow when too many files are in the directory.
After importing OIDs the current N-View configuration should be saved to disk for the imported OIDs to be present when this configuration is used again. If you have more then one network configuration stored on your disk and you want the imported OIDs to take effect in all your network configurations you can choose a N-View configuration file in the parsers file dialog for OIDs of that file to be imported into the current network configuration.
