1 Welcome to Network Discovery CHAPTER Thank you for using Network Discovery. This book is intended for the Network Discovery Administrator, the person who will have the most control over the setup and operation of Network Discovery. This information is critical to your success with Network Discovery.
Network Discovery Peregrine Desktop Inventory can contribute data to Network Discovery Peregrine Desktop Inventory (PDI) scanners can be scheduled from Network Discovery and scan files can be added to a shared directory on the Peregrine appliance, so the scanned devices will appear in the Network Discovery database, and on the Network Map. For more information on setting up PDI to contribute data to Network Discovery, see Using Network Discovery with Desktop Inventory and Desktop Administration.
Setup Guide Start by collecting information about your network The Pre-Setup Questionnaire is available in the next chapter of this manual (see Pre-setup Questionnaire on page 15), from your sales representative, or as a Word file from http://support.peregrine.com. Note: If you wish, you may fill in the questionnaire and send it to Peregrine customer support. They can review your information and provide feedback on how you set up Network Discovery.
Network Discovery 14 | Welcome to Network Discovery
2 Pre-setup Questionnaire CHAPTER Your contact information Your Name Organization Address Telephone E-mail Fax Describe your network’s node and subnet setup Enter the following information to help determine the scale of your network.
Network Discovery Note: Network Discovery defines a node as any network device with at least one MAC address. A managed device is a network device that has an SNMP agent and MIB so it can respond to SNMP requests.
Setup Guide Peregrine Systems Customer Support access Information on the options you have for receiving Customer Support is in Choose how to receive Peregrine Systems Customer Support on page 27. If you will use a modem and a dedicated analog telephone line, enter the number of the telephone line. Telephone number for access by Peregrine Systems Customer Support List IPv4 ranges for Network Discovery to discover Network Discovery uses IPv4 ranges to discover the devices in your network.
Network Discovery From To IPv4 range 4 IPv4 range 5 IPv4 range 6 List IPv4 ranges for Network Discovery to avoid If there are subsets of the above IPv4 ranges that you do not want Network Discovery to discover, enter them here. Important: You do not need to enter ranges outside the ranges you have specified. Network Discovery does not discover ranges unless you specify them.
Setup Guide account will be able to manage the device from the Network Discovery interface. . Rights granted Community string Associated device /IPv4 range Read Write Enter TCP/IP configuration The Peregrine appliance must have its own static IP address, but it can manage devices with either static or dynamic IP addresses. Please enter the following information to show how the devices on your network receive IP addresses.
Network Discovery Are TCP/IP addresses static or dynamic? Static_________ Dynamic_________ Is SNMP management enabled on the DHCP server? Yes ________ No________ Enable SNMP management on the DHCP server so that Network Discovery can poll the DHCP server ARP cache for the current IP and MAC address pair information of the devices on your network.
Setup Guide What server will you use for the Peregrine appliance? Warning: Do not mirror your hard drives, and do not install RAID in your Peregrine appliance. If you do, your appliance will not function properly.
Network Discovery Server Type Checkmark Large - 4GB, 2 CPUs ________ HP DL380 Large - 4GB, 2 CPUs ________ Note: Any of the “Large” appliances can be turned into a “Medium” appliance by removing 1 CPU and 2 GB of RAM. Send the questionnaire When you have completed the questionnaire, send it to Peregrine Systems Inc. by e-mail, mail or by fax. To find the mailing address or fax number of the Peregrine office in your region, contact your OEM/VAR or check http://support.peregrine.com.
3 Prepare the network CHAPTER The following flowchart shows all the important tasks that must be completed to prepare your network. There are other optional tasks described throughout the chapter.
Network Discovery Turn on SNMP management in all routers and core switches Depending on the device, this may be a case of enabling an existing SNMP agent or setting up an SNMP agent. You may also turn on SNMP management in other devices. The more managed devices in your network, the better. However, enable switches and routers first. Note: If you use HSRP (Hot Standby Routing Protocol) in your network, ensure you turn on SNMP management in all the affected devices.
Setup Guide Set DHCP lease time If you use DHCP (Dynamic Host Configuration Protocol) in your network, set the IP address lease time to at least 7 days and turn on SNMP management on the DHCP servers. About community strings A community string is like a password. A device uses a community string to protect its SNMP MIB—and it’s the data from the SNMP MIB that Network Discovery relies on. Network Discovery must know at least one of a device’s passwords to collect data from that device.
Network Discovery What happens if a device with directed community strings is not configured with the IP address of the Peregrine appliance? Network Discovery will behave as though the device does not have SNMP management turned on. Network Discovery will appear to work, but you’ll eventually notice that it is working poorly. Once Network Discovery is up and running, the Exceptions reports can advise you of problems.
Setup Guide Choose how to receive Peregrine Systems Customer Support Options for allowing Customer Support access (in the order in which Peregrine Systems recommends them) are as follows: through Internet access through a Virtual Private Network over Internet by a modem and a dedicated analog telephone line through a Remote Access Server (RAS) Through Internet access For you to have Customer Support by means of the Internet you must enable certain ports in the corporate firewall.
Network Discovery Used for Port Applet Server 8109/tcp Note 1. Depending on your settings for Appliance proxy services 2. If you have an Aggregator license Virtual Private Network over the Internet Contact Peregrine Systems Customer Support to send them the software that will enable access. If you have a firewall, enable the firewall ports listed in the above table.
Setup Guide If you have a corporate firewall that could impede Network Discovery, configure the corporate firewall to allow ICMP (ping) to pass through, and enable the following ports: Used for Port Echo Reply Note From To 0/icmp device Peregrine appliance Error Messages 3/icmp device Peregrine appliance Echo Request 8/icmp Peregrine appliance device TTL Timeout 11/icmp Peregrine appliance device device Peregrine appliance 5 Netmask Request 17/icmp Peregrine appliance device Ne

Setup Guide Check Cisco devices It is strongly recommended that firmware/software in your Cisco devices be IOS version 12 or higher. If you want ATM or Frame Relay support, IOS 12 is mandatory in your Cisco devices. (Optional) Enable UDP port forwarding on routers If you want to have your Peregrine appliance communicate with listener agents across subnets, you will need to enable routing for the UDP packets.
Network Discovery 2 Enter the following commands: configure terminal interface [source interface] ip helper-address [destination listener] (repeat this command for each appliance you want to send to) exit ip forward protocol udp 1738 end Note: Any interface can have multiple helper-addresses. Note: The “ip forward protocol upd” command specifies the ports to forward. In this case, we recommend port 1738.
4 Compatibility Matrix CHAPTER You must install the Network Discovery software onto a server meeting the following hardware requirements. For a new installation, the IBM xSeries 335, Dell 1750 Server, or HP DL360/DL380 are recommended. However, the IBM xSeries 330 or Dell 1650 can also be used.

6 Appliance Management CHAPTER The following flowchart shows all the important tasks that must be completed to set up your appliance. There are other optional tasks described throughout the chapter.
Network Discovery Log in to Network Discovery To log in to Network Discovery, you must have the following: access to a web browser with Sun Java 1.4.2 or 1.5 enabled Javascript enabled pop-up windows enabled the IP address or domain name of the Peregrine appliance a valid Network Discovery account name and password Network Discovery is shipped with four pre-defined accounts.
Setup Guide Note: Account names are all lowercase. Passwords are case-sensitive. “PASSWORD” and “password” are two different passwords. 4 Once the account name and password are accepted, the Network Discovery Home page and Toolbar appear. After the Toolbar appears, but before it is activated for use, your browser will display one or more security warnings. You are asked to grant Network Discovery permission to run. Click the check box next to “Always trust content from Peregrine Systems, Inc.
Network Discovery concentrator, switch, or router as the Peregrine appliance, at least during your first use of Network Discovery. Try pinging the IP address of your Peregrine appliance. If the Peregrine appliance does not respond, try pinging the concentrator or switch to which the Peregrine appliance is attached. If the concentrator or switch also does not respond, the problem is probably not with the Peregrine appliance.
Setup Guide Your management workstation and the Peregrine appliance are on opposite sides of your corporate firewall. You should see a dialog box that explains that Network Discovery is trying to connect and shows an error message. To resolve the problem, do one of the following: Ensure that your management workstation and the Peregrine appliance are on the same side of the firewall.
Network Discovery Three rows of navigation hyperlinks appear at the bottom of the Home page (as well as at the bottom of the Report, Status, Administration, and Help windows). Links to major features First row of hyperlinks shows where you have been Bottom rows are is Toolbar buttons The Network Availability graphs give you an idea of how your network is performing. In this example, you can see the appliance has been running for approximately 1.5 months.
Setup Guide The Toolbar The Toolbar provides a way to navigate through Network Discovery. The Toolbar has three main parts: banner or title bar buttons status window There are three groups of Toolbar buttons. Some buttons may be unavailable, depending on your license. Banner shows name of Peregrine appliance Buttons link to major features. Status window The banner or title bar The Toolbar banner displays the system name.
Network Discovery Assign a system name, contact, and location “System name” is the name of the network or part of the network that Network Discovery is currently managing. The system name is displayed in the Toolbar banner. “System contact” is the Network Discovery Administrator. “System location” is the physical location of the Peregrine appliance. These are standard SNMP entries; assign them according to your corporate policy.
Setup Guide Change the Peregrine appliance community strings We recommend that you: Change the Peregrine appliance’s read-only string to the one used by the rest of the devices in your network. The read-only community string allows read access to the Peregrine appliance MIB. Change the Peregrine appliance’s read/write community string (for security reasons). The read/write community string allows read and write access to the Peregrine appliance MIB.
Network Discovery 2 Type the new read-only or read/write community string in the appropriate field. 3 Click Change. Set the time zone Note: You must set the time zone when you first configure Network Discovery. Changing to the appropriate time zone will allow Network Discovery to adjust the local time relative to Coordinated Universal Time. Network Discovery will also calculate daylight savings time automatically as appropriate. The default time zone is Canada/Eastern.
Setup Guide Note: When you change the time zone, some software modules restart and you may see a Start Log message. This is normal. Network Discovery may not be available for a couple of minutes. (If you change it later, when there is more data, Network Discovery could be unavailable for 20 to 30 minutes.) Select the correct time zone Click Change Enter the domain name server A domain name server translates between alphabetic domain names—also known as DNS names—(for example, “website.example.
Network Discovery To enter the domain search order 1 Click Administration > Appliance management > Domain name servers. 2 Type the new domain search order in the bottom field. When you enter the domain names in either field, separate the entries with commas. For example: “example.com,eastern.example.com,sales.example.com”. Default domains are used to extend domain names so that it is possible to enter domain names in “Find” in a shorter form.
Setup Guide Enter the host name A host name allows you to refer to a device by a name rather than an IP address. Network Discovery uses the host name to refer to itself in the e-mails it sends. Note: Define a domain name server before changing the host name. The Host name page has two modes: prompted and manual. In prompted mode, Network Discovery will try to read its own host name from the domain name server.
Network Discovery (Optional) Enter the Workgroup name Enables you to change the NetBIOS workgroup name. Workgroups are used primarily by Microsoft Windows. The workgroup name determines where in your Network Neighborhood you will find the Peregrine appliance. The Peregrine appliance has a shared directory into which you can deposit: license files when you receive them from Peregrine Customer Support updated software components scan files The current workgroup name is shown below.
Setup Guide (Optional) Enter the Administrator e-mail address Enter the e-mail address of the Network Discovery Administrator, and that address will receive information on mail delivery problems. If you enter an e-mail address that is not valid, you will cause “message undeliverable” e-mails to be sent to the account of the administrator for the mail server. This account is normally called “postmaster”. Consult your mail server’s documentation for details.
Network Discovery (Optional) Enter the SMTP server An SMTP server handles standard Internet e-mail. Network Discovery can use this server when it generates e-mail messages to tell you what is going on in your network or with other processes such as a daily backup. If you do not enter an SMTP server, e-mail from Network Discovery will go to the default SMTP mail server for the domain. You may prefer to specify an SMTP server because the e-mail will go faster routed through a local server.
Setup Guide 2 Enter the Host name or IPv4 address of the SMTP server. 3 Click Change. Set the system time Network Discovery uses the system time to monitor your network, to generate reports, and to adjust to daylight savings time automatically. Perform one of the two following procedures, not both. Set the date and time on page 85 Synchronize the time on page 86 (or Enter an NTP server to synchronize the time (continually) on page 87) Important: Make sure you set the time and date correctly.
Network Discovery Note: Seconds are not set explicitly. When you click the Set Time button, seconds are set to 0. To set the time and date 1 Make sure the time zone is set (see Set the time zone on page 78). 2 Click Administration > Appliance management > Set time. 3 Enter the Year, Month, Day, Hours, and Minutes in the appropriate fields. 4 Click Change Time.
Setup Guide 3 Enter the IPv4 address of the server with which you want to synchronize time. 4 Click Synchronize Time. The time is now the same as the server you synchronized with, but the times may diverge later. Enter an NTP server to synchronize the time (continually) Entering an NTP server is optional. An NTP (Network Time Protocol) server is a server that keeps track of and reports the exact time. Network Discovery can synchronize its system time with the time reported by the NTP server.
Network Discovery Change the default Admin password Note: You should change the password for the default admin account as soon as possible for security reasons. For additional security suggestions, see Security Checklist on page 153. Note: When you change the password for the admin account, you will have to log in again. (It is always necessary to log in again when you change the password for the account you are using.) Passwords can be 4–20 characters long by default.
Setup Guide About disabling warnings The use of a UPS (Uninterruptible Power Supply), an internal modem and regular backups of Network Discovery data are all highly recommended. Network Discovery generates warnings if it does not detect a UPS or modem or if daily backups have been configured but are not occurring. You can, however, choose to turn these warnings off.
Network Discovery To enable or disable the UPS warning 1 Click Administration > System preferences > Display warnings. 2 For UPS warnings enabled, click Yes or click No. 3 Click Change. Disabling modem warnings Network Discovery generates warnings if it does not detect an internal modem. If you have chosen to receive customer support through the Internet, over a Virtual Private Network or over a Remote Access Server, you can disable this modem warning.
7 Licenses CHAPTER Peregrine Systems makes increased functionality available through license files you can install once you receive them from Peregrine Customer Support. Request a new License Install the new license How it works To see what licenses are currently installed on your Peregrine appliance, see Status > Current Settings > Installed Licenses. You request a license upgrade from Peregrine Systems, directly through Network Discovery.
Network Discovery You can use Network Discovery with this default license temporarily, or you can go ahead and request the license that will give you the full functionality you purchased, as well as the most up-to-date software components. Maintenance contracts entitling you to periods of support from Peregrine Systems Customer Support are also distributed in the form of licenses. Evaluation License If a Peregrine appliance in your network has an expired evaluation license, it cannot be aggregated.
Setup Guide Environment poller Mapping engine (connectivity) Request a new license If you purchased Network Discovery from an Original Equipment Manufacturer or a Value-Added Reseller, follow your OEM/VAR’s instructions to obtain a license. You can send a request for a new license in two ways: The Peregrine appliance can send an e-mail message directly to Peregrine Systems Customer Support. You can copy the information into an e-mail and send the e-mail manually.
Network Discovery Install the new license Peregrine Systems Customer Support generates your new license file and sends it to you attached to an e-mail. Note: If the license asks the Peregrine appliance to do too much, (for example, a license for more devices than the Peregrine appliance can support) the Peregrine appliance will take the maximum it can do. Note: To see what licenses are currently installed on your Peregrine appliance, see Status > Current Settings > Installed Licenses.
8 Set up Network Discovery CHAPTER The following flowchart shows all the important tasks that must be completed to set up Network Discovery. There are other optional tasks described throughout the chapter.
Network Discovery Important: If you are using Network Discovery with Desktop Inventory, you must follow the steps outlined in Using Network Discovery with Desktop Inventory and Desktop Administration. How it works Essentially, network configuration works as follows. You add IPv4 ranges that you want Network Discovery to monitor. Then you enter pieces of those IPv4 ranges that you want to be monitored differently or not at all.
Setup Guide Note: The list of community strings must be separated by commas (for example, “public,private,string1,string2”). 3 Click Change. Note: Hop 0 (zero) is always the Peregrine appliance itself, and hop 1 is always the default gateway. Run Router Discovery 1 Click Administration > Router discovery > Run router discovery. 2 Click Confirm. You will receive an e-mail confirmation when Network Discovery has completed the router discovery process.
Network Discovery Import your IPv4 ranges from a CSV file Instead of entering all your IP ranges manually, you can import them from a CSV file. The file must be set up properly, as in the example below. State whether this is a range or a subnet Starting IP address Ending IP address or netmask Define whether this is a Property Group or Property Set (Set, Network, Community, Scanner, Listener) The name of the Property Group or Property Set you’ve specified in the previous column.
Setup Guide Groups/Sets in the CSV file, and you do not select a default, the IP range will not be imported. 5 Click Import. Once you import the CSV file, you will see a report explaining whether or not the import was successful. Read the report carefully to ensure that all your IPv4 ranges have been imported properly. Note: By default, Network Discovery will insert the “global” IPv4 range of 0.0.0.0 - 255.255.255.255, even if you have not listed it in your CSV file.
Network Discovery To delete an IPv4 range 1 From Administration > Network configuration > List IPv4 ranges. 2 Select the IPv4 range. If the range has subranges, Network Discovery gives you a choice of deleting only the range or of deleting the range plus all of its subranges. 3 Click Delete this IPv4 range. 4 Click Delete. You have deleted the range in your proposed new configuration, but your change will not take effect until after you have reviewed and activated your changes.
Setup Guide 3 For Property Set/Group, select Network: Active Discovery. Network Discovery will perform network discovery (ping, poll, and table read) on the range you have entered. 4 Click Submit. Repeat step 1 to step 4, if necessary, for all your subnets. You have added the range(s) to discover to your proposed new configuration, but your changes will not take effect until after you have reviewed and activated your changes.
Network Discovery Add ranges for DHCP servers and unmanaged routers If you have one or more DHCP servers or you have unmanaged routers, add their IPv4 addresses and apply the appropriate Property Group so that Network Discovery will monitor the ranges differently. To add IPv4 addresses to be treated as DHCP servers or unmanaged routers 1 Click Administration > Network configuration > Add IPv4 range. 2 Enter the starting and ending IPv4 addresses for the DHCP server or unmanaged router.
Setup Guide Here’s how it works. You give community strings to a Community Property Group and then apply the Community Property Group to an IPv4 range. For now, just add all your community strings to one Property Group, the “global” Community Property Group. Note: Community strings are case-sensitive. “PUBLIC” and “public” are two different strings. To add community strings to the global Community Property Group 1 Click Administration > Network configuration > Community Property Groups.
Network Discovery Activate your proposed changes The Activate Changes page allows you to review all the changes you have proposed for Network Discovery network configuration before actually making those changes take effect. Note: Changes to network configuration do not take effect if you do not activate them. To activate changes 1 Click Administration > Network configuration > Activate changes. A table appears, detailing all the changes you proposed in this session.
Setup Guide Peregrine Systems recommends waiting at least 48 hours while Network Discovery is first discovering your network. If you have concerns after that, call customer support. Are devices appearing on the Network Map? Within the next few minutes, you can check that network discovery is occurring. To check that network discovery is occurring 1 Click Status > Appliance Health > Software Environment. 2 See if the number of discovered devices is increasing. 3 Open a Network Map.
Network Discovery To check the Device Filters Report Click Status > Filtered devices To see a full list of possible filters, click Help > Classifications > Device Filters. Check the Device Modeling Queue During the initial discovery of your network, the modeling queue may show devices, depending on the size of your network and how quickly Network Discovery is discovering and modelling devices. At most other times, the queue will be empty.
9 Refining Network Discovery CHAPTER The procedures in this chapter are optional. You may wish to come back to this chapter after Network Discovery has been up and running for a while. Here you will learn how to take advantage of the precision Network Discovery offers you for setting up Network Discovery.
Network Discovery You can leave discovery set up that way, if it is satisfactory to you. In fact, if there is a lot of change in your network, leaving it alone may be the best thing to do. However, you can set discovery up more precisely. For instance, you may want to reduce overhead on the network, or you may have a lot of community strings for security reasons and want to set up separate ranges for them. You can pick out IPv4 ranges or individual devices for Network Discovery to handle differently.
Setup Guide You will be creating a tree of ranges and the tree can be as complicated as necessary to have Network Discovery monitor your network the way you want. Note: A range can consist of one device. The starting and ending IPv4 addresses are the same. Note: If you decide that two adjacent IPv4 ranges really should not be separate, you can merge them. The ranges must have identical properties or you cannot merge them.
Network Discovery To merge IPv4 ranges 1 Administration > Network configuration > Merge IPv4 ranges. Network Discovery displays all adjacent ranges sharing identical properties along with what the results of merge will be. 2 Click Merge. You have merged any adjacent identical IPv4 ranges in your proposed new configuration. Property Groups Network Discovery comes with default property groups you can apply to the IPv4 ranges you set up.
Setup Guide Administration > Network configuration > Network Property Groups > List Network Property Groups The list is a table with the names of the groups on the left and the names of the properties across the top.
Network Discovery The following properties are in every Network Property Group: Property Purpose Hardcoded Default Setting Allow devices Allow devices to be added Off Actively ping Actively ping devices for discovery Off NetBIOS query Query devices for their NetBIOS names (the computer user names) Off Resource/Environment manage Query devices for resource management Off Force ARP table read Force ARP table to be read Off Accumulate IP Addresses Accumulate IP addresses instead of Off repla
Setup Guide How to use Network Property Groups Some of the property groups cause Network Discovery to give you more data than others, but in doing so they also generate more traffic on the network and cause more load on the device being monitored. It can be a trade-off, a balance between efficiency and performance. You might choose to do less discovery on some parts of the network and more on others. Property Group Purpose global The starting point, assigned to the 0–255 range.
Network Discovery Property Group Purpose Passive Discovery Network Discovery does not actively look for devices, but will include them if it happens to find them. (For example, Network Discovery may be able to gather the information from the ARP cache of a device.) Restrict to scanned-only For IPv4 ranges where there are only devices that should be found by Peregrine Desktop Discovery (PDI). Remove Address Used for removing IP addresses from the device model.
Setup Guide Create a Network Property Group Add a Network Property Group 1 Administration > Network configuration > Network Property Groups > Add a Network Property Group. 2 Give your new Property Group a name. 3 Give your new Property Group a description. 4 For each parameter, click On or Off or leave it at the default value, Inherit. 5 Click Submit. Delete a Network Property Group You can delete a Network Property Group that no longer meets your needs and is just cluttering up the list.
Network Discovery Apply a Network Property Group to a range You might think of it as adding ranges that you want to subtract in some way from the preceding range. Each successive range that you add takes all its properties from the range of which it is a subset—except the properties you specify for it. The “child” inherits properties from its “parent,” except for the properties you give it. For example, you might set up Network Discovery to resource manage all devices from 172.22.1.212 to 172.22.1.
Setup Guide To create a Community Property Group 1 Administration > Network configuration > Community Property Group > Add a community property group. 2 Give a name to the Community Property Group. Use a name that is meaningful to you. 3 Add a description. 4 Under the heading Add a Community String enter a string name, and select the appropriate Type (read or write, or both). 5 Click Add. 6 Repeat steps 4 and 5 for each community string that can be applied to the same set of devices or subnets.
Network Discovery More on community strings If you do not add any community strings, but keep “public” (the default) in the list, Network Discovery will attempt to read the MIB of all devices in the defined IP range or set of ranges using only “public.” Note: If you do not add any community strings and delete “public” from the global Community Property Group (that is, if no community strings are defined,) Network Discovery will not interrogate any devices in your network.
Setup Guide either disable all such traps or use only a single correct community string for each device that issues a trap. Note: If another network management system is used in the same network with Network Discovery, this other system may generate alarms due to these traps.
Network Discovery You have deleted a single community string from a Community Property Group in your proposed configuration, but your change will not take place until you activate changes. To delete a Community Property Group 1 Click Administration > Network configuration > Community Property Groups > Delete a community property group. 2 Select a Community Property Group from the pull-down list and click Select. 3 Click Delete.
Setup Guide the strings you added. It’s a shortcut to save you from entering IPv4 ranges more than once. You should always give your Property Sets meaningful names, for example “servers” or “routers” so you can apply it to specific portions of your network. You can list, add, modify and delete Property Sets, the same way you do with Property Groups. Reviewing and activating your configuration changes Remember that you must activate any changes to the system in order to have the changes take effect.
Network Discovery 2 If you wish to see details on the proposed changes to the IPv4 ranges, you can click on the tree diagram to expand it. New ranges appear in green. Changes to existing ranges are in yellow. Removed ranges are in grey. 3 Review the changes to make sure the new configuration is correct. If you decide to implement the changes you have made, applying the changes will update your network configuration. You can also discard all changes.
10 Setting up Accounts CHAPTER Once you have set up the Peregrine appliance and configured Network Discovery, you will want to set up accounts. For each account, you can set the name, password, and other important information. Make sure anyone who needs to work with Network Discovery has an account, and knows the limits of their account level.
Network Discovery How many people can use Network Discovery at once Network Discovery supports a maximum of 250 accounts. More than one account can be used at a time. Up to six accounts can view a Network Map simultaneously. Up to 20 accounts can use any part of Network Discovery other than the Network Map simultaneously. How the types of accounts differ Each type of account has different permissions. The principal difference between the types of account is the amount of administration permitted.
Setup Guide You should also modify the capabilities of the account and the contact data for the person who owns the account. You can also modify the properties of the account, but this is optional; the account owner can perform these actions on his or her own account. Whether you just create an account or whether you customize each account for each owner is your decision.
Network Discovery After you create an account, a shortcut menu appears. You can use the shortcut menus to continue working with the account. To create a password for an account Note: Alternative: If you see a brief menu on the screen, click Modify account password, then skip to Step 4. 1 Click Administration > Account administration > Account password. 2 Select the account from the list box. 3 Click Modify Account. 4 Enter an account password in both boxes.
Setup Guide To change an account type 1 Click Administration > Account administration > Account capabilities. 2 Select the account from the list box. 3 Click Modify Capabilities. 4 Select the account type from the list box. Note: You should have a single Administrator account. That account should be reserved for use by the Network Discovery Administrator. If you have more than one Administrator account, there is a danger that each Administrator account will overwrite the work of all the others.
Network Discovery Note: You can make changes to your own account at Administration > My account administration.
11 Backup and Restore CHAPTER Every day, after midnight, Network Discovery saves its data to a backup partition on the Peregrine appliance. In addition, you have the option of saving the data externally to an FTP site or to a tape. If necessary, you can restore the data from either the internal or the external backup or, if necessary, from another Peregrine appliance.
Network Discovery internal backup. Once the internal backup is complete, Network Discovery sends that internal backup to the FTP site and/or to the USB tape drive. When you restore data, you also have two options. You can restore either from the internal backup or from the external backup. Important: After a restore, there may be phantom alarms on the Health Panel and in the Alarms Viewer for the first sampling period, because the events log has been affected by restoring from an old backup.
Setup Guide Windows 2000 Professional (IIS 4) Red Hat Linux: Kernel 2.2.12, ProFTPD version 1.2.6 For a recommended USB tape drive, see Appendix C, Extra Hardware on page 157. Note: For FTP backups, you must have read/write permission on the repository device. Tip: For increased security on FTP backups, create a special account on the repository device with very few security privileges.
Network Discovery The default is Off. Note: The tape option does not appear if you do not have a tape drive connected. However, the tape option does still appear, if you disconnect the tape drive after you have configured the external backup as “Tape On”. Note: If you have just restored a backup from an older appliance that did have a tape drive installed, the tape option may appear even though you no longer have a tape drive installed.
Setup Guide 4 valid characters: A–Z, a–z, 0–9 @ (at symbol), . (period), - (hyphen) length of input: 4–50 characters Enter the password for the FTP server (required). 5 6 7 length of input: 4–20 characters Enter the host name or IPv4 address of the FTP server (required). valid characters: A–Z, a–z, 0–9 @ (at symbol), .

Network Discovery 10 Choose whether or not you will back up scan files. (Scan files will take up a lot of space.) 11 Click Submit. Network Discovery will now back up its data to the FTP site once a day. You can check the backup log at any time by clicking Administration > Backup and restore > View backup log. The list of backups is sorted by time and date. Testing your external backup and restore To make sure you have entered the correct information for your FTP server, you can test the link.
Setup Guide To test your external FTP backup 1 Click Administration > Backup and restore > Test external backup. 2 Select FTP. 3 Click Test. A screen appears showing your FTP configuration information. 4 Click Confirm. A message appears, telling you if the test was successful or not. To test your external tape backup Important: Testing an external tape backup erases any data previously stored on the tape. 1 Click Administration > Backup and restore > Test external backup and restore.
Network Discovery Warning: If tape backup is selected, the tape in the drive will be erased. To back up your data immediately 1 Click Administration > Backup and restore > Run external backup now. 2 Click Backup now. Creating an internal backup If you select this option, you will send the active data to the backup partition immediately. Note: If Network Discovery is configured to run an external backup, forcing an internal backup forces an external backup too.
Setup Guide To restore your data from an internal backup 1 Click Administration > Backup and restore > Restore from internal backup. 2 You can choose whether or not you will keep your current scan files if there are none in the backup. 3 If Network Discovery has been set up for e-mail, choose whether or not an e-mail notification will be sent and to whose account. 4 Click Restore. Network Discovery will not respond for a short period. This is normal.
Network Discovery Restoring from tape If you have configured a backup USB tape drive, you can use this procedure to restore your data. To restore your data from a tape 1 Click Administration > Backup and restore > Restore from tape. 2 You can choose whether or not you will keep your current scan files if there are none in the backup. 3 If Network Discovery has been set up for e-mail, choose whether or not an e-mail notification will be sent and to whose account. 4 Click Restore.
Setup Guide Step 1: Setup your new Peregrine appliance Perform the procedures as detailed in this Setup Guide, Chapter 5, Install and Start Network Discovery. If your new appliance will have the same IP address as the old appliance, do not connect the new appliance to the network yet. You will do that later in this process. Step 2: On your old appliance, do an internal backup Click Administration > Backup and restore > Run internal backup now.
Network Discovery Step 3: Connect the crossover cable between the two appliances Connect a cross over cable to Ethernet port 2 on the Peregrine appliance.
Setup Guide Ethernet port 2 on the IBM 336: Use Ethernet port 2 for the crossover cable Ethernet port 2 on the Dell 1750: Use Ethernet port 2 for the crossover cable Ethernet port 2 on the Dell 1650/1850/2650: Use Ethernet port 2 for the crossover cable Restoring your data | 141

B Security Checklist CHAPTER Although your Peregrine appliance will operate even if you do not follow these procedures, we strongly recommend that you take the following steps to reduce risk. Step 1 Place your Peregrine appliance behind your institution/corporation’s firewall. The Peregrine appliance stores a lot of information about your network. You do not want this information to be publicly available.
Network Discovery Step 3 Eliminate known account names “admin” “itmanager”, “itemployee”, and “demo.” Create a new Admin account for the Network Discovery Administrator. (optional) Create a new Demo account for training users. Log into the new Admin account. Delete the accounts named “admin”, “itmanager”, “itemployee”, and “demo.
Setup Guide There is information about accounts in Chapter 10, Setting up Accounts on page 123 and there is information about event filters in the Network Discovery User Guide. Step 5 Change the Peregrine appliance’s default password (“Appliance”) in the configuration interface.
