Program adjustments (Preferences)


The Window is accessible from menu Settings-> Preferences.

General

Autosave settings - saves settings of the program in INI a file automatically at an exit from the program. By default INI file is in the folder %USERPROFILE %\Application Data\NetView\NetView.ini for WIN'NT/2000/XP or in folder WINDOWS in Win9x systems. You can change placement of ini file to NetView's folder by creating ini in NetView's folder before starting it.

Autostart on windows startup - automatically start NetView at system startup.

Low priority while starting - sets priotity of thread that loads hostlist to lowest level, for smoother startup.

Minimize to tray - enables an icon in tray, which image depends on state of NetView. Right click on an icon it is possible to access the context menu with a set of the basic functions. If at you the three-push-button mouse you can open NetWatcher by a clique on the middle button on a tray icon.

Minimize on close -minimizes NetView to tray on close main window

Don't show message boxes on errors and warnings - "silent" mode at which netview does not show any messages. It is useful for autonomous work.

Startup by autostart delay - helps to remove problems with the postponed start of drivers. (When netview it was started and the network still is not present Æ:-)).

 

 

Hostlists options.

Here you can specifi path and name to file in wich all information about hosts, hostlists, lines and areas will be stored. This file also automatically loads after NetView starts. Having pressed button Edit you can edit a file in Notepad.  Provisional lines from a file:

 *NetView hostlist created on 2003/1/12 at 19:42.8 

192.168.7.10 killer ** some_stuff * - 

ipxhost ** some_stuff* * 

$list$192.168.x.x ** UTP Cat5E* 

It It is better do not touch some_stuff



Re-read hostlist - by enabling of this option NetView will re-read hostlist from a file at every refresh

Autosave hostlist - by enabling of this option NetView will keep hostlist at every refresh

Don't backup hostlist - by default NetView creates two backup copies of .NVH file on startup. Checking this options forces NetView do not backup hostlist

 

Edit default settings for newly added hosts - click here for edit settings for new hosts that are added by hostlist refresh, from Network scaner, NetWatcher or plug-ins and scripts. For example you can change default hostlist where new hosts appears automatically after addition from Default to something other.

Automatically clear following DNS suffixies: - Specify here what DNS suffixies should be delete automatically from hostnames. Enter here * to delete all suffixies or enter some suffixies divided by character ';'. For example "home.org;our.net"

Visual map host image max size: - specify here maximum size of host's images. Any images that will be larger will be automatically resized to match this size. 

Highlight opened in this session hosts for: - NetView highlights hosts that was opened for specified here period of time after opening. Highlighting will be reset on next recheck. 

Autosort hostlist - After every recheck all lists, which not in Visual Map mode are automatically sorted.

Show notes as caption - If hostlist in Visual map/plan view mode this option enables displaing of host's notes as caption, instead of hostnames.

Alternative Visual map middle scroll - You can scroll visual map by pressing middle mouse button and moving mouse. This option inverses scrolling direction and increases scrolling speed.  

Raise alert if any host changed state to online - a global mode of the notification about host's goes online

Raise alert if any host changed state to offline -a global mode of the notification about host's goes offline

 

Opening options

Open using hostname - opens machines by their names. All the same that you will enter in Run \\ hostname. The maximal compatibility.

Open using IP address - opening occurs by IP address that works faster on NT/2000 systems. Under win95 it similar at all does not work. Under 98 and ÕÐ works, but more slowly than by name. Sometimes, in multisegment networks, with incorrectly adjusted name server it is impossible to open hosts by their names. By IP, as a rule, all works fine.

Open in Window - opens computers by default (by doubleclick or ENTER) in a window

Open in Explore - /../ In a catalog tree of Windows Explorer

Open in Custom program - -/../In the mentioned below program, for example, Total Commander.

Open normal - the window opens in a normal size

Open maximized - /../ maximized

Open minimized - /../ minimized

Force recheck on opening - rechecks host state before opening

Open offline -tries to open a computer even if at last recheck it was offline

Don't show hidden resources - disables NetView's ability to search hidden shares (that wich names are ended by '$')

Single click open -To open hosts by single mouse click. Some people likes this.

Try firstly FTP passive mode connection - by default, if both active and passive FTP modes enabled NetView tries firstly Active mode. This option forces NetView to try Passive mode at first.

Random auto-authorization user-name: - if NetView gets Access denied error on shares enum its tries to connect to host with specified here logon username, where '#' charachter repleced with and random digit. If you specify here empty string then NetView will not try to logon under other username. This can be usefull in domains or if remote system has account-locking feature enabled.

 

Recheck

Optimize Windows TCP/IP stack - by default WIndows uses ports numbers from 1024 to 5000 for outgoing connections, and, besides, every used port number blocked for consequenced using for 240 seconds. This limits can cause problems with allocating many sockets at once, how NetView does. Enabling this option forces Windows to use port numbers from 1024 to 65534 and free port after 30 second after closing socket.

Using scan ports -check will be perfomed by attempt to establish TCP connection with given IP addresses on the given port. If specify port 139 (by default) - all machines on which the NETBIOS over TCP/IP service is enabled will be shown ad online. If specifi here port 80 - that you find out addresses of all online HTTP servers. Common TCP ports you can read the list in file COMMPRTS.TXT and in file CPORTS.LST - this file is the basic the list of comments to ports for NetView and in all ports are marked with + will be listened by IP logger'îì. You can specify here up to 8 ports, divided by charachter ';' and learn what ports are opened by looking for value of metavariable "scan"

Maximum simultaneously opened sockets: -Specify here how many simultaneously opened sockets NetView can use for recheck by port scans. Decreasing this value takes more time for perfoming recheck, but decreases load to routers and your system and intensifies reliability of recheck. 

RAW sockets for port scans - by default when perfoming rechecks with port scanning NetView creates socket for every scanned object and calls connect() API. When enabling this options NetView creates only one RAW socket for scanning of all objects - this saves system resources, but RAW sockets accessible only on Windows 2000 and higher and only if NetView started by local system administrator or is running as the service. Warning: this option can work inproperly if firewall is running on your machine. So if after enabling this options all hosts switched to offline - disable it.

 

Using ping -check will be carried out by pinging IP addresses by ICMP echo request with 32 bytes of data and the given waiting time of the answer. Check will be carried out tries times up to the first answer. If answers are not received - host is offline

Try ARP request if ping recheck failed - this option enhances PING recheck: if host from your segment don't reply on pings then NetView will test if host reply on ARP requests. Not recommended for usual using because it uses broadcast ARP packets. Enable it only if you really know what you want.

 

Force host's recheck by IP packet, initiate delay: -this option is allowed only on Windows 2000 and higher and correctly working only if NetView started by Administrator or Local system account (as service). When this option is enabled NV will force rechecking of any checkable offline host by receiving IP packet from it. Such forced by IP packed recheck can occurs only one time after every global recheck. So NV can practically momentally reacts on events of any host turned on, if it sends any packets that arrives host where NV is running. Host's recheck will be forced after specified here count of milliseconds after receiving an IP packet from it. Warning: this option can work inproperly if firewall is running on your machine.

Resolve host's IP before every recheck- This option is neccesary in DHCP networks, if enabled IPs of all hosts will be automatically updated before every recheck

Automatically initiate flobal recheck every ## seconds - will carry out automatic recheck of the list by the timer every ** seconds. Take into account that for hosts in the individual order it is possible to establish count of missed global rechecks. It allows to set the various periods of rechecks

Autorefresh - updates the list of machines after every list recheck by interrogating a network and re-reading .NVH (if enabled).

Disable searching for new hosts on startup - do not interrogate a network on presence hosts at start. At the list there will be only those hosts, which are in a .NVH file. This mode temporarily can be toggled on startup by pressing SHIFT at start of the program and having released at the beginning of recheck.This option is recommended to be checked if you want to have maximum reliability do not lost hosts from hostlist.

Look for hosts only in specified workgroup - alternative method of interrogation of a network, available only under Win'2000 and higher. Allows specifing workgroups where NetView will search for new hosts, also when using this mode NetView retrieves and stores to metavariable "os" information about what OS is installed on found hosts.

IP to hostname scan and conflicts resolve method: - Method which NetView will use for determination of the hosts's names by their IP addresses in different situations. The possible variants are Standard, using NETBIOS and their combinations. The Standard method tries to resolve the host's name on by its IP address using DNS reverse lookup or by WINS. In general results of this  this method depends on configuration of DNS or WINS server of the network, rather then from that as user of the target computer has named its computer that can cause some problems. Method of the determination of the host's name by NETBIOS'à works only if this NETBIOS is enabled on that host and if it will give you this information. But then this name will exactly that name under which host is visible in Windows Network and besides this method can work quicker than standard. Combinations of methods can be used to try in the beginning to define the name by using of standard method and if failed - then by NETBIOS or on the contrary.
