� If you are installing SciFinder Scholar on Windows 2000 or XP, reviewAppendix B before beginning installation.

� There are three installation options: Typical (recommended), Compact,and Custom. During a Typical installation, the SciFinder Scholarinstaller:

- Determines if SciFinder Scholar is installed in the chosen folder or thedefault folder. If it is already installed, you may overwrite or cancelthe installation.

- Checks the system configuration for any known installation problems.For example, it checks that Windows 98 or higher is installed.

- Installs a plug-in if Netscape or Firefox are located in the defaultlocation

- Copies SciFinder Scholar files to their appropriate locations- Removes SciFinder Scholar files in the event of a partial or failed

installation

� During installation, you are asked if you have a disk labeled �CustomSite Files.�

For the first installation at your site, click No. For all subsequentinstallations, answer this prompt according to whether or not you areadding or updating the site.prf file during installation. For details, seeDistributing SciFinder Scholar and the site.prf File.

Questions to Consider about Installation:� Who is responsible for installing software - users, IT staff, other?� How is software deployed - CD-ROM, remote installation, download from

local server, download from CAS server?

8 Installing SciFinder Scholar

SciFinder Scholar must be customized to log on with your SciFinderScholar site-specific login ID and password. Networking, server, firewall,and source port information may also be customized to meet yourorganization�s needs.

These customizations are known as Site Preferences, and they are storedin an encrypted file called site.prf, which is normally located in the mainSciFinder Scholar folder. The Site Preferences Editor (SPEdit) allows youto create, view, and change the contents of site.prf.

The site.prf file must reside on each workstation at your site. Whenever avalue stored in the file is changed, the updated site.prf must be madeavailable to all users to whom the change applies. See DistributingSciFinder Scholar and the site.prf File for details.

Use the table below to determine if a new site.prf file needs to bedistributed.

If a new site.prf is not needed, skip to Testing Your Connection.

Site Preferences

Site Preferences 9

A new site.prf is neededif any of these apply:

This is the first version of SciFinder Scholarinstalled at your organization.

The networking values need to be changed.

To test the existing values, try to log on afterinstalling SciFinder Scholar or perform aconnectivity test. For details, see NetworkingOptions and Testing Your Connection.

You need to add or update the SciFinder Scholarlogin ID(s) and/or password(s). For details, seeScholar Login Options.

You wish to change the file location for the SciFinderScholar online Help. For details, see Scholar LoginOptions.

A new site.prf is notneeded if:

You installed SciFinder Scholar 2006 in the samefolder as a previous version and none of thechanges above are needed.

Running SPEdit

After SciFinder Scholar is installed, you may create or edit site.prf byrunning SPEdit.

1. Select Start > Run.2. Enter the path for the SciFinder Scholar executable file in the Open

dialog box. After the path, type /spedit preceded by a space.

Tips for entering the path:� To ensure the correct format is used, click the Browse button

and find the path.� Depending on your operating system, you may need to enclose

the path in quotes.

For example, if you installed SciFinder Scholar in the default locationc:\sfschlr, type:

�c:\sfschlr\sfschlr.exe� /spedit

3. Click OK.

You will be asked for a SPEdit password.

1. Type the password spedit.2. Create a new password, which will be your SPEdit password that

only you will know.3. Type and confirm the password.4. Click OK.

Note: If you forget the SPEdit password you created, delete thesite.prf file housed in the main SciFinder Scholar folder. Then redothe Running SPEdit step and create a new password.

The SciFinder Scholar splash screen displays followed by the PreferenceEditor window. Two tabs, Networking and Scholar Login, identify themain customization categories.

Scholar Login Options

Click the Scholar Login tab to set up login IDs and passwords and setdefaults for inactivity timeouts and Help file location.

Login Information

If your organization has only one login ID and password, enter them onthe first line of the Scholar Login tab. Enter any string of characters,e.g., xxxx, in the description box.

When your organization has multiple login IDs and passwords, SciFinderScholar allows you to provide a choice of service types when a userbegins a session. This feature provides the ability to support multipleservice agreements on a single desktop installation, as opposed to uniqueinstallations and icons for each service arrangement.

Enter the login ID, password, and a description of the account for each ofthe service types you would like to make available to users at yourorganization.

12 Site Preferences

Upon login, the user is presented with the service types you have set up.

The user selects a service type and proceeds with logging on toSciFinder Scholar.

Your institution�s SciFinder Scholar login IDs and passwords as well asyour SPEdit password are confidential. Only the SciFinder Scholar SiteAdministrator should have knowledge of this information.

Inactivity Timeout

By default, SciFinder Scholar shuts down after 20 minutes of inactivity.To change the default, adjust the value for Automatic Shutdown after Xminutes of inactivity.

Help Files Location

By default, the most recent version of the online Help files is accessedfrom the CAS web server. In addition, a static copy of the files is placedon each user�s computer during installation. If you wish to access thelocal copy, rather than the copy at the CAS server, change the Help FilesLocation to Local.

Change SPEdit Password

The SPEdit password that you created during the Running SPEdit stepcan be changed by clicking the Change Spedit password button.

Site Preferences 13

Setting Site Preferences

To set your Site Preferences, click OK. If you have technical questions orproblems with Networking, Scholar Login, or Programs, contact CASfor assistance.

If you did not test your connection at the end of the SciFinder Scholarinstallation, you can test the connection by either trying to log in toSciFinder Scholar or performing a connectivity test.

To log in to SciFinder Scholar, double-click the SciFinder Scholar iconlocated in the main SciFinder Scholar folder. You may alternatively launchthe SciFinder Scholar application from the Start menu or double-click yourdesktop icon, if you created one after installation. Your connection issuccessful if the SciFinder Scholar splash screen and the LicenseAgreement display.

To perform a connectivity test:

1. Select Start > Run.2. In the Open box, enter:

c:\sfschlr\sfschlr.exe -scicastest_connectivity3. Click OK.

Note: The connectivity test requires a Site Preferences file (site.prf) thatcontains either a valid login ID and password or the test login IDscicastest_connectivity and password 123Z456.

Your connection is successful if a confirmation message displays. If yourconnection is unsuccessful, a Problem Report provides information to helpyou make a connection to the SciFinder Scholar servers at CAS.Problems may involve the site.prf file, firewall configuration, or both.

Testing YourConnection

Testing Your Connection14

The SciFinder Scholar application and a current site.prf (Site Preferences)file must be installed on each user�s computer. The application can bedistributed in the following ways:

� Download from a local server: Place the SciFinder Scholarinstaller (.exe file) on a local server for each user to access. Thisis the preferred method because the download will likely be faster.

� Download from a campus web site: Provide users with accessto the SciFinder Scholar installer from a campus web site withcontrolled access.

In either case, if the user is upgrading from a previous version of SciFinderScholar, instruct them to install SciFinder Scholar 2006 in the existingSciFinder Scholar folder. The previously used site.prf file is retained.

If this is the first installation or if an updated site.prf file is needed, the filemay be distributed in one of the following ways:

� Adding site.prf during installation: Copy the new or updatedsite.prf file to a floppy disk, and assign the volume label sfcustomto it. To assign the volume label:

1. Insert a disk into the floppy drive.2. Double-click My Computer.3. Right-click the floppy drive (usually A:\), and select Properties

from the pop-up menu.4. In the Label box, type sfcustom.5. Click OK.

Write Custom Site Files on the disk�s external adhesive label, andprovide disks to individual users for use during installation ofSciFinder Scholar 2006. The installer asks the users if they have adisk labeled Custom Site Files. They should click Yes and follow theinstructions. The site.prf file is copied into the main SciFinderScholar folder.

� Adding site.prf after installation: Provide users with the new orupdated site.prf file in the manner that is best for your organization,e.g., via a shared directory. Instruct users to install SciFinderScholar 2006 and respond No when asked if they have a Custom SiteFiles disk. Users should then manually copy the site.prf file into themain SciFinder Scholar folder after installation.

Appendix A:ConnectivityDetails forNetworkAdministrators

Network Requirements

SciFinder Scholar is a client/server application that communicates overthe Internet or another TCP/IP (Transmission Control Protocol/InternetProtocol) compliant network. Optimal performance is obtained using adirect Internet connection or business-to-business VPN.

By default, SciFinder Scholar assumes transparent pass-through ofZ39.50 packets between the SciFinder Scholar client on the user�scomputer and the SciFinder Scholar server at CAS. There is no methodwithin SciFinder Scholar to allow users to log in to either their networkor firewall when logging on to SciFinder Scholar.

If your organization does not have a direct Internet connection, dial-upInternet access can be used, provided that all connectivity and licenserequirements are satisfied. Some functions will be affected in a dial-upenvironment, and modem speed will significantly affect response time.A 56K modem, or ISDN, DSL, or cable modem, is recommended.

Note: SciFinder Scholar uses the source IP address in addition to thelogin ID and password for authentication. Therefore, the connection mustpresent an authorized campus IP address.

SciFinder Scholar may be used from off-campus locations, provided thata connection to the campus network can be made before launchingSciFinder Scholar. The connection may be dial-up, ISDN, VPN, orInternet proxy.

For information related to security issues, see Appendix F.

Questions to Consider about Networking:� What is your network operating system (OS)?� Do you have multiple domains, subnets, or campuses?� What type of Internet connection will you use - direct network, indirect

network, modem?

Questions to Consider about Remote Access:If you will offer remote (off-site) access to SciFinder Scholar, answer thefollowing:� How will remote users access the campus network - dial-up, VPN, Internet

proxy, other?� What hardware and/or protocols will be employed - 56K, ISDN, or cable

modem, VPN, PPP/SLIP, other?

Connectivity Details for Network Administrators16

Firewalls or Proxy Servers

SciFinder Scholar can be used with a variety of firewalls and proxyservers. If your organization uses a firewall, gateway, router, or proxyserver to control communications internally and externally, the device mayneed to be modified to allow passage of the Z39.50 protocol on port 210.

SciFinder Scholar does not obtain proxy information from web browsers.Firewall and proxy settings must be configured within the Networking tabof the SciFinder Scholar Site Preferences Editor.

Note: SciFinder Scholar supports SOCKS 4 and may support SOCKS 5.With SOCKS 5, the firewall challenge/response must be disabled.

For details, see Networking Preferences.

Questions to Consider about Firewalls and Proxy Servers:If you have a firewall and/or proxy server, answer the following:� Who is your firewall administrator?� What OS and software (version and patch number) are used?� What are the internal and public IP addresses of the proxy?� Is this a proxy array? What caching schema is used?� What proxy services are enabled - HTTP (are you HTTP 1.0 or 1.1

compliant?), Winsock, SOCKS (are you SOCKS 4 or SOCKS 5 compliant?),other, none?

Connectivity Details for Network Administrators 17

Networking Preferences

The remainder of this appendix describes options available in theNetworking tab of the Site Preferences. Instructions for accessing theseoptions are provided in Running SPEdit.

Z39.50 Networking Information

SciFinder Scholar must be able to connect to CAS at the IP address ofthe SciFinder Scholar server (IP 134.243.85.3) and the destination TCP/IPport on that server (port 210). CAS no longer has a separate backupaddress and port, but you may use these boxes to accommodate yourfirewall or proxy.

The default configuration assumes that there is transparent pass-throughof the Z39.50 protocol via port 210 between the SciFinder Scholar clientand server. If this is not the case, changes to information on theNetworking tab may be required, depending on the configuration of yourfirewall.

Connectivity Details for Network Administrators18

Non-SOCKS Firewalls

If you have a non-SOCKS firewall or a proxy server, it may need to beconfigured to accommodate the Z39.50 protocol via port 210. Plus, yourfirewall must allow the SciFinder Scholar client to connect to theSciFinder Scholar server at IP 134.243.85.3.

Networking or firewall staff at your organization should determine theappropriate changes:

1. Enter the IP address or domain name of the internal side of thefirewall in the Primary Address field.

2. Enter the appropriate TCP/IP port in the Primary Port field. This isthe port you have mapped it to on your firewall. CAS stronglyrecommends that you use port 210, which is the registered port forZ39.50 protocol.

3. Enter the IP address or domain name of the internal side of thefirewall in the Backup Address field. If you do not have a separatebackup address, use the same name or address as the PrimaryAddress.

4. Enter the appropriate TCP/IP port in the Backup Port field. This isthe port you have mapped it to on your firewall.

5. Ensure that Use Z39.50 SOCKS Firewall is not selected.

Note: You may use Network Address Translation (NAT) for IP address orport translation, as long as packets are sent to the SciFinder Scholarserver at IP 134.243.85.3 and port 210.

Connectivity Details for Network Administrators 19

SOCKS Firewalls

If you are using a SOCKS firewall, edit the information on the Networkingtab as follows:

1. Select the Use Z39.50 SOCKS Firewall option.

2. Enter the IP address or domain name of your SOCKS firewall in theSOCKS Firewall Address field.

3. Enter the TCP/IP port of your SOCKS firewall in the SOCKS FirewallPort field.

Note: SciFinder Scholar supports SOCKS 4 and may support SOCKS 5.With SOCKS 5, the firewall challenge/response must be disabled.

Source Port

Select Override Source Port to allow the SciFinder Scholar client tooverride the local source port assignment. (The TCP/IP stack on yoursystem assigns the local port unless an application overrides it.) WhenOverride Source Port is selected, SciFinder Scholar uses the localsource port specified in the Starting Port field instead of the default portprovided by the TCP/IP stack. If a connection attempt fails using thestarting port as the source port, the source port is incremented by oneand tried again. The source port continues to be incremented by one untila connection is established or the number of tries equals the valuespecified in the Number of Attempts field.

If a connection has not been established, then the Backup Address isused and the source port continues to be incremented by one until asuccessful connection or the specified number of attempts is reached.

Connectivity Details for Network Administrators20

Installation on Windows 2000 or XP 21

The default security structures for Windows 2000 and Windows XP restrictthe typical user from installing software. In some cases, the typical useris prevented from creating, deleting, or modifying files in many folders onthe hard drive, except those within their own profile.

Generally, there are three primary user groups to which a user can belong:Administrator, Power User, or Authenticated User.

In a campus environment, the Administrator determines permissionsassigned to groups for tasks such as program installation and creation,deletion, and modification of files. In many cases, the default settings forthe Authenticated User group prevent you from successfully installingSciFinder Scholar or may result in permission issues when runningSciFinder Scholar.

In a home environment, you are likely a member of the Administratorgroup, having complete control of all files and folders. Usually, you will nothave any installation or run-time errors with SciFinder Scholar installations.

Installation to C:\Sfschlr (Default Location)

To install SciFinder Scholar to the default location, the person performingthe installation or upgrade must have the following permissions:

Permissions FolderRead, Write, Modify, Create, Delete C:\Sfschlr and subfoldersRead, Write, Modify, Create, Delete C:\Program FoldersRead, Write, Modify, Create, Delete C:\Program Files\Accelrys and

subfoldersRead, Write, Modify, Create, Delete Default TEMP directory

(%Temp% and/or %tmp%)Read, Write, Modify, Create Windows Registry files

Installation to a Nondefault Location

To install SciFinder Scholar to a nondefault location, e.g., the ProgramFiles folder, the person performing the installation or upgrade must havethe following permissions:

Permissions FolderRead, Write, Modify, Create, Delete C:\Program Files\Sfschlr and

subfoldersRead, Write, Modify, Create, Delete C:\Program Files\Accelrys and

subfoldersRead, Write, Modify, Create, Delete Default TEMP directory

(%Temp% and/or %tmp%)Read, Write, Modify, Create Windows Registry files

Appendix B:Installation onWindows 2000 orXP

A typical list of in-house journals includes ISSN and CODEN informationfor journals that an organization has available in-house or through privatefull-text arrangements. A file containing the ISSN and CODEN informationis uploaded to CAS by the Site Administrator for use by all users at thesite. The file does not need to be distributed to each user�s computer.

The following steps are required for uploading an in-house list:

1. Call CAS to set up your account with administrator priviledges.Your account may already be set up in this way.

2. Create an in-house list according to the instructions that follow.3. Point your web browser to my.cas.org.4. Enter your SciFinder Scholar login ID and password.5. Click Upload Journal Lists to access the tools for maintaining

journal lists. Click Need Help? for additional information.

Once uploaded, the list specifies which journals ChemPort offers within theIn-House Linking options.

Creating an In-House List

Use any text editor, e.g., Notepad, to create a file containing ISSN andCODEN information. If Microsoft® Word is used, save the file in Text Only(.txt) format.

Files should follow this syntax:

ISSN:CODEN XXXX YYYY (where XXXX = start year, YYYY = end year)

Syntax guidelines:

� Each journal is on its own line.� ISSN is required for each journal; CODEN and years are optional.� Follow ISSN with a colon only if the CODEN is given.� ISSN:CODEN and years are separated with spaces.� If only one year is given, it is interpreted as the start year.� If an end year is given, it is interpreted as the last year the journal

was available.� If multiple year ranges apply for a journal, create multiple entries.� If you have both electronic and print ISSNs, create multiple entries.

Note: Supplying both ISSN and CODEN allows SciFinder Scholar toidentify many more references than ISSN alone.

Examples:

1217-89690001-4842:ACHRE40097-6156:ACSMC8 19970904-213X:ACHSE7 1996 19981318-0207 1990 1994

Appendix D:Troubleshooting

24 Post-Processing SciFinder Scholar Answers

As a service to SciFinder Scholar customers, CAS provides filter files forthe purpose of importing SciFinder Scholar data into third-partyapplications, e.g., EndNote, ProCite, and Reference Manager. These filesare located in the Filters folder within the main SciFinder Scholar folder.

Each of the files represents one of many possible solutions for importingdata and may be modified to meet your needs. We suggest that you firsttry them on a small data file. Details about how to transfer SciFinderScholar answers to these applications are available at www.cas.org/Support/scholar.html.

In addition, the latest versions of the above-mentioned bibliographicmanagement programs include SciFinder Scholar filters within thestandard supplied filter folder. For tips on adding and using supplied filters,review the filter documentation for those programs.

SciFinder Scholar is a TCP/IP client/server product that uses the Z39.50communications protocol. TCP/IP is the communications mechanismused by Internet computers. Z39.50 is an application-level informationsearch and retrieval protocol used primarily by on-line services.

Three security-related questions you might have regarding SciFinderScholar:

1. How secure is SciFinder Scholar through my organization�s firewall?

It is recognized that any communication passing through a firewall isa potential concern to the organization behind the firewall, soSciFinder Scholar has been designed to be firewall-secure:

� The SciFinder Scholar client initiates all communications exceptduring periods of inactivity. During these periods of inactivity, theserver at CAS polls the client requesting confirmation that the clientis still there. Other than the exception mentioned, the SciFinderScholar server only acts in response to client requests. TheSciFinder Scholar server will never initiate a connection to a client.

� All communications take place on a registered port: 210. If firewalland client modifications are required by your network securityrequirements, we strongly recommend that port 210 is used as thedesignated Z39.50 port on your firewall

� All client communications are with a single, well-known CAS server,IP 134.243.85.3.

Appendix F:SecurityInformation

Appendix E:Post-ProcessingSciFinder ScholarAnswers

2. What about IP spoofing?

A network attack in which a �bad� computer is configured tomasquerade as a �good� computer is called IP spoofing. For a spoofto be successful, a rogue computer must be able to convince clientsthat it is the target (good) computer. The more customized a networkservice is, the more difficult it is to spoof. For this reason, IP spoofingattacks usually target general network services such as �telnet,� andnot highly unique services such as the Z39.50 protocol which is usedby the SciFinder Scholar client and server for application-levelcommunications. Additionally, the goal of a spoof is to attack acomputer by exploiting network �trust� in a client/server relationship(�trust� in a network context means that one side of a client/serverconnection implicitly trusts the other side and so does not require theother side to authenticate itself). Because SciFinder Scholar doesnot use network trust, it would be a poor target for a network spoof.

3. Are my communications private?

To enhance data confidentiality, SciFinder Scholar never sends plain-text ASCII data. All network communications are encoded using BER(Basic Encoding Rules). BER performs a translation (�scrambling�) ofdata. Both sides of a SciFinder Scholar client/server connectionBER-encode their data just prior to sending it. The receiving sidedecodes the data by inverting the translation.

More information about the Z39.50 protocol is available at its MaintenanceAgency Home Page at the Library of Congress, lcweb.loc.gov/z3950/agency.
