INTERNET IN A BOX 1.0A Documentation Addendum This addendum describes corrections to the Internet In A Box documentation, and additional information about Internet In A Box for release 1.0a. The following new features are described in this addendum: Support for SLIP and Advanced SLIP/PPP Options (Internet In A Box now supports both SLIP and PPP Internet accounts; you can specify SLIP or PPP during installation, and configure advanced settings for SLIP and PPP (such as PAP and CHAP) in the Configuration Utility and the Dialer.) SprintLink/InterServ Summary Information Change (If you choose to set up an account with SprintLink/InterServ, you will now have the ability to save your information to a file, and will be asked to verify your Email and access account passwords.) Application Enhancements (Network File Manager: Passive Open FTP) (AIR Mail: Sent Mail Folder, Return Receipt Feature) (AIR Mosaic: Drag and Drop Support) (Dialer: BOOTP Support) Corrections In the trademarks section in the front of the Installation & Configuration Guide and Getting Started, the following credit should be added: Mosaic was developed by the National Center for Supercomputer Applications at the University of Illinois at Urbana-Champaign. This version is being distributed under a licensing agreement with Spyglass, Inc. Installation & Configuration Guide On page 9, the third paragraph should read: If you want to use AIR Mail (the Internet In A Box electronic mail application), the Service Provider must be able to provide you with a mail account that uses POP3. POP3 (Post Office Protocol) is a popular protocol used for Internet mail. If you do not have a POP3 mailbox, you will not be able to use AIR Mail. You will, however, be able to send mail in other applications, such as AIR News and AIR Mosaic, that send mail. On pages 81 and 101, there are listings for NETCOM. NETCOM is not offering third party SLIP/PPP accounts at the current time. On page 75 and 94, the listing for Alternet indicates that it offers worldwide service; in fact, Alternet offers nationwide service. Getting Started Guide On page 28, the first paragraph says that AIR Mosaic can only print text; this is incorrect. AIR Mosaic can print text and graphics and will print most WWW home pages accurately to a laser printer. Use the Print Preview command to see how the document will print. The Whole Internet User's Guide, Special Edition On page 236, the second paragraph says that AIR Mail will not automatically quote the original message when responding using Follow Up. This sentence is meant to refer to AIR News (AIR News does not use AIR Mail to follow up or reply to news articles), and is incorrect: AIR News does automatically quote the original message when using Follow Up. Support for SLIP and Advanced SLIP/PPP Options Internet In A Box now incorporates support for SLIP (Serial Line Internet Protocol). SLIP is a protocol used for dial-up access to the Internet, similar to PPP. Therefore, you can now use Internet In A Box with both SLIP and PPP connections from Service Providers (if you have a choice of accounts, PPP is recommended). All references in the Installation and Configuration Guide to PPP should now be assumed to apply to both PPP and SLIP. You can also configure advanced options for SLIP and PPP, such as the use of CSLIP, PAP and CHAP authentication protocols, a variety of compression methods, and more. The changes in Internet In A Box are described below. Installation Change If you are using an Internet Service Provider other than SprintLink/InterServ, there will be another step in your installation/configuration process. After you fill out the screen with information about your account with the Internet Service Provider, you will see a dialog, asking you to specify whether your service provider uses a SLIP or PPP network interface. Choose SLIP or PPP. (The default is PPP).The Settings button allows you to configure advanced settings for SLIP or PPP. In most cases, you will not need to configure these advanced settings unless directed to by your service provider. If your service provider uses an authentication protocol like PAP or CHAP, you will need to configure advanced settings. See the next section, "Configuring SLIP and PPP", for information on configuring SLIP and PPP. When you click OK, you will proceed to the next dialog, . Configuring SLIP and PPP You may not have to configure SLIP and PPP to have Internet In A Box work properly with your Internet Service Provider. However, there are a number of settings you can change, if necessary. You can configure SLIP and PPP from the dialog (described in the last section), by selecting SLIP or PPP and choosing the Settings button. The dialog is presented during installation and can also be reached by choosing Interface from the Dialer Network menu. You can also reach the dialog from the Configuration Utility by clicking Connection and Dialer Setup, and then clicking the Interface button. SLIP Settings The following options are available for SLIP. Address Acquisition. You can now specify whether your IP address is Static or Dynamic. Static is the default method used. Static Addressing means that you are required to use one IP address (that never changes). Dynamic addressing means that you are assigned a new IP address each time you start a SLIP session. Your Internet Service Provider or network administrator will be able to tell you which method you will use. (Hint: if you are assigned a specific IP address for your account, such as 165.121.6.6, then you are using static addressing). If you choose Static addressing, the address you provide in the dialog will be used as your IP address. If you choose Dynamic addressing, the address you should use will be sent back from the SLIP host when you connect, and the Dialer will extract it ("parse" it) from the host screen each session (it will change each session). Often, it is the first address that is sent back from the Dialer. In some cases, however, the SLIP host will send back several different addresses (such as an IP address and a gateway address). In those cases, you need to specify which address should be used as your IP address (check with your service provider if you are not sure). You should indicate which address on the screen should be used by selecting 1st, 2nd, 3rd, 4th, or 5th for the "Parse the ___ IP Address sent from the remote host" option. Compression If the SLIP host you are connecting to supports CSLIP (Compressed SLIP transmission), you can have the Dialer use CSLIP. Click Enable VJ CSLIP to enable CSLIP compression. This will result in better, faster performance with your host; however, you do not have to enable it in order to work with that host. Maximum Transmission Unit The MTU (Maximum Transmission Value) represents the size in bytes of data sent in SLIP packets. In most cases, you will not have to change this value; change it only if directed to by your Service Provider or Network Administrator. The default MTU used for SLIP is 1006. PPP Settings The following options are now available for PPP. You will only see the first option, Authentication Protocol, at first; you can click the Advanced button to set more advanced options. You can change the options in this dialog to configure PPP for your particular host or service provider. Note that many of these options are advanced; changing them may produce unpredictable results. If at any time you want to set these options back to their original settings, click the Default button. Authentication Protocol None/PAP/CHAP Some PPP hosts use authentication methods like PAP or CHAP to verify that you are a valid user of an account. Authentication may be used in conjunction with a standard login/password (known as "clear text login") or as a standalone method that does not require you to login to the host directly, but passes the authentication information directly to the host. If the only method you use when connecting to your host is an authentication method like PAP or CHAP, you should make sure the Login Method in the dialog (found using Login Setup in the Dialer Network menu) is set to None. PAP (Password Authentication Protocol) is a popular method of authentication requiring a PAP username and password. These will usually be different from your login ID and password, if you have one. If you choose PAP, you can configure the PAP Username and Password by clicking the Settings button, next to the PAP option, and filling out the information in the provided dialog. You do not have to fill out this information here, but if you do not, you will have to provide it during login. (You may wish to leave the password blank for security purposes). CHAP (Challenge/Handshake Authentication Protocol) is another method of authentication used by some hosts. CHAP is not supported in this release, but will be supported in future releases of this product. None is the default setting for Authentication Method; you should always use this setting, unless your host uses PAP or CHAP, above. Active Open/Passive Open This indicates what method is used to start PPP, Active Open or Passive Open. A PPP transaction is like a conversation between two machines; in this case, your machine and your Service Provider's PPP server. One of the machines has to initiate the conversation, and the other has to respond. The Dialer assumes that the remote Internet Service Provider is Active Open, meaning that it will initiate the conversation with the Dialer. In some cases, the Internet Service Provider will be Passive Open, which means that they will not initiate a conversation. (even if you type "PPP" or another command to initiate PPP, they may not initiate it). If this is the case, choosing Passive Open from this dialog will cause the Dialer to send an additional command (a Packet Command) to initiate PPP on the remote host. This will be rare for most Service Providers you will encounter; most of them will be Active Open. Compression Method PFC/ACFC/VJ The Compression section specifies several different methods of compressing data that will be sent over a PPP connection. These methods are PFC (Protocol Field Compression), ACFC (Address and Control Field Compression) and VJ (Van Jacobsen IP Header compression). The options above specify which parts of a PPP packet are compressed when sent. Some or all of these methods may be "understood" by your PPP host; whatever options are set here will be used by the Dialer. General Options MRU/ACCM/Magic Number Negotiation MRU (Maximum Receive Units) indicates the size in bytes of data that is received in PPP packets. The allowable range is 128-1500. The default value for this option is 296. Note: In cases where you are doing batch file transfers or other operations involving large throughput, you may want to increase the size of the MRU to improve performance and increase speed. However, increasing this value will slow down interactive operations (like reading news articles or using Mosaic). ACCM (Asynchronous Control Character Map) indicates whether PPP will use the Asynchronous Control Character Map, and indicates a value to be used. A default value of FFFFFFFF is provided. Magic Number Negotiation can be selected. This will allow use of a magic number, a unique number that is used to identify you by the remote host. This option is on by default. Using SLIP You can now connect to a SLIP (Serial Line Interface) host using the Dialer. The login and connection procedure is virtually the same as with a PPP host, with the following exceptions: Using Manual Login: After you login, type a password, and (optional), issue a command to start SLIP, you MUST start Packet Mode using the Pkt Mode button on the Dialer Toolbar or the Start Packet Mode command in the Dialer Network menu. Using Auto Login: You can set up auto login to automatically connect to your SLIP host just as you would a PPP host, except that (as noted above), you MUST issue a Packet Mode command to initiate the connection. In the Auto Login, you do this by selecting the Start Packet Mode command in the last Auto Login event (typically, the event that contains the command to start SLIP, if there is one). Change to SprintLink/InterServ Summary Information If you set up a SprintLink/InterServ account, you receive information in a screen. You now also have the option of saving the information in this screen (including the passwords you will need to connect to your access account and to start AIR Mail) to a file. You can do this by clicking the Save button in the screen. The information in this dialog will be saved to the file PASSWORD.TXT, in your \IBOX\DATA directory. Be sure to save, print, or write down your passwords before leaving this screen. You will now also be asked to verify your login and e-mail passwords after you exit the screen. Network File Manager: Passive Open FTP In the Network File Manager application, you can now specify the Data Channel Establishment method using the dialog. The Data Channel Establishment option allows you to specify what method you want NFM to use when establishing data channels for file and list transfers. The FTP protocol which NFM uses to present remote host file systems allows two methods by which NFM can establish data channels on which it transfers files or file lists, active or passive. NFM by default uses the active method (NFM actively establishes data transfer channels (uses PASV command) in the dialog) because this method works with most hosts, even hosts using Internet firewalls. You should not have to change this selection, in most cases. If, for some reason, you need to use the passive method (NFM passively establishes data transfer channels (using the PORT command) in the dialog) you can change it in the dialog. AIR Mail: Sent Mail Folder AIR Mail now includes a Sent Mail folder, which can automatically store all of your sent mail. This is a system folder, and cannot be deleted. By default, this folder is not used, since keeping sent mail will use up disk space on your hard drive. You can store outgoing mail in your Sent Mail folder by checking the "Keep a copy of outgoing messages in Sent Mail folder" option. All messages you sent will automatically be stored in the Sent Mail folder. You can treat messages in this folder as if they were in any other folder; deleting them, moving them to other folders, etc. AIR Mail: Return Receipt Feature You can now request a return receipt in AIR Mail. This means that when you send a message, you can have a mail message sent to you to acknowledge that the mail was received by the remote mail server. This does not acknowledge that the person you are sending mail to has received the mail, only that the mail arrived at the server. You can request a return receipt by clicking the Options button in the dialog (obtained by clicking Compose). You should then check Request Return Receipt in that dialog. When you send the message, a receipt will be requested. When the remote mail server receives the message, you will be sent a mail message titled: "Returned Mail: Return Receipt", which includes the body of the message you sent. This is the return receipt. Note: You must check the Request Return Receipt option every time you compose a message, to receive a return receipt; this option is not automatically remembered. AIR Mosaic: Drag and Drop Support You can now drag and drop Mosaic documents to the Windows File Manager, or to other applications that support drag and drop, such as Windows Notepad. When your mouse cursor is over a hyperlink, click and hold down the mouse button until the cursor changes from a pointing finger to a document icon, with the caption WWW. Continue holding down the cursor, and drag the icon to the application where you want to drop the item. (If the application will not let you drop the item, the cursor will change into a prohibited symbol (a circle with a slash through it)). Note that not all applications will support drag and drop from Mosaic, even if they are OLE-compliant (Windows Object Linking and Embedding). Dialer: BOOTP Support You can now configure the Dialer to use BOOTP to obtain your IP address from the remote host that supplies your connection. BOOTP is a method that is used by some remote hosts to assign you an IP address "on demand". Your Service Provider or network administrator should be able to tell you whether you use BOOTP. (Most hosts do not use BOOTP; they instead used a fixed IP address or dynamically assign an IP address). There is now an option in the dialog for "Use BOOTP Configuration". Check this option if you need to use BOOTP to get your IP address. 14 Internet In A Box 1.0a Addendum Internet In A Box 1.0a Addendum 15 #IB30-ADDNDM
