----------- isn: How to connect across VCS/ISN boundaries. ----------- Holmdel, Crawford Hill, and Short Hills locations have mostly ISN nodes. Other locations have primarily VCS (Datakit) nodes. In general, ISN nodes issue the 'DIAL:' prompt, and VCS nodes issue the 'DESTINATION:' prompt. The following examples should prove helpful in establishing connections across the above network boundaries. The example destinations are "ih/f/iwlca" on VCS, and "hod/houxa" on ISN. ISN to VCS: Type '1/toll' at the 'DIAL:' prompt. Then type 'ih/f/iwlca' at the 'DESTINATION:' prompt. VCS to VCS: Type 'ih/f/iwlca' at the 'DESTINATION:' prompt. VCS to ISN: Type 'ho/toll/isn' at the 'DESTINATION:' prompt. Then type 'hod/houxa' at the 'DIAL:' prompt. ISN to ISN: Type 'hod/houxa' at the 'DIAL:' prompt. ---------------------------------------------------------------------- -------------------- netdir_doc: Netdir Tutorial. -------------------- WHAT IS NETDIR: Netdir is an on-line database of essential system information. Presently, its scope is limited to AT&T systems, both those connected to the Datkit network, as well as those which are not. As need arises, the netdir database will be updated periodically to reflect recent changes and additions. The information contained in each data base record consists of: NAME: the name of the system, eg. 'ihuxa' TYPE: system type, if available, eg. 'vax11/780' NET ADDRESS: network address as 'area_code/exchange/host' (note that some hosts are not on the network) DIALUP: direct dialup numbers, if available PATH: uucp path; replace '%s' with login name ORG: name of organization ADDRESS: mail address CONTACT: contact(s), system administrator(s), etc. BASIC USAGE: When invoked, netdir displays the following prompt: "PLEASE ENTER SYSTEM NAME: " The name of the system for which information is being requested should be entered at this point. Example: 'ihuxm'. AT this point netdir searches the data base, and displays the retrieved record(s). If the specified system is not found in the database, an appropriate message is displayed. HOW TO USE SPECIAL CHARACTERS: In order to make the retrieval more flexible and to allow the retrieval of groups of systems with a single query, netdir supports a limited regular expression capability. The following special characters are recognized: ? matches any single character * matches any string [] character class. examples: [ayb], [A-Zg-h], [a-z0-9]. There is presently no way to 'escape' the meaning of these special characters. If any of the above are used, it is recommended that the search pattern end with '*'. Examples: ihux*, ihnp[0-7]*, ??uxa, *vax*, i?ux?, etc. HOW TO SEARCH USING KEYS OTHER THAN SYSTEM NAME: It is possible to search the netdir database using a key other than the system name. To do this, enter '~key' at the netdir prompt. You will be asked to choose a search key, and then to enter the search pattern. HOW TO STAT THE VERSION: Typing '~version' at the netdir prompt will display the version of the database, as well as the version of the program. ONLINE COMMAND SUMMARY: Typing '?', 'help', etc. at the netdir prompt will display a summary of netdir usage. DIFFERENT FROM DIRECTORY ASSISTANCE: Netdir is *not* the same as Datakit VCS Directory Assistance, hence it does not recognize search strings such as 'k/?', 'ih//?' etc. These are entered at the "DESTINATION: " prompt. Please consult the Datakit VCS User's Guide for information on how to use Directory Assistance. REQUEST FOR COMMENTS: Please direct comments/suggestions regarding the netdir program to [ihnp4!]ihnp1!mth. Please direct comments regarding the netdir database content to [ihnp4!]ihnp1!action, or the IH Help Desk, x3333. Thank you. ---------------------------------------------------------------------- -------------- people: Important people contacts at IH. -------------- General information: Doug Cummings x4142 Tom Okapal x4311 Service orders: Thresa Martin x6359 Wiring: Dan DeChirico x2211 Ray Serafinn x4510 ---------------------------------------------------------------------- --------------- dug12: [D.U.G.] Glossary of Messages. --------------- ************ Messages Issued By Datkit VCS ************ CONTROL COMPUTER OVERLOAD Usually indicates that all computer ports are in use, or that the entire modem pool is in use. IS AN INVALID DESTINATION is not a valid address for Datakit. Enter "netdir" or "?" at the "DESTINATION: " prompt to verify host address. INVALID DESTINATION Indicates that the connection requested cannot be completed for one of several reasons: all ports busy on a host or trunk, or an improper/incomplete host name or destination was specified. Unfortunately, this message sometimes also indicates that the computer controlling one of the Datakit nodes is momentarily busy. IS BUSY All computer ports for are in use. NETWORK ROUTING ERROR Indicates an all ports busy on an alternate route to the host. Try again later. This is now used in place of "control computer overload."

To help troubleshoot problems, the NODE, MOD, and PORT information for both ORIGINATE and DESTINATION connections is required on each trouble ticket. This data can be obtained by entering "display" in the DK command mode (see infor item 'dug10'.) It is also imperative that the circuit number be reported on the trouble ticket. This number is stamped on the Datakit VCS jack that your terminal is connected to. It is not essential to enter the trouble ticket on your terminal. Any working terminal can be used. The trouble ticket entry is menu driven, and guides youn through the entry process. At the end, your report is assigned a six-digit number. Save this number for future inquiries. To enter a new trouble ticket, or inquire on the status of an existing one: ENTER: "trouble" at the "DESTINATION: " prompt. Although the above method is preferred, troubles can also be reported to the Help Desk, x3333. ---------------------------------------------------------------------- ------------------ dug10: [D.U.G.] DK Command Mode. ------------------ This mode is used to communicate directly with the Datakit VCS controller. The mode is identified by a "DKC" prompt on the screen. Enter the "DKC" mode by depressing the key twice within one second. This may be done at the "DESTINATION: " prompt, or when logged into a host. The following are the DK commands. Items tagged with '*' are not currently in service. COMMAND ABBREVIATION EXPLANATION ------- ------------ ----------- continue c,cont Returns you to the previous network connection * c new [tag] New call; hold current call with 'tag' * c tag1 [tag2] Switch to 'tag1'; hold current call with 'tag2' disconnect d,disc Drop the current network connection * d tag Drop call held with 'tag' * d all Drop all held calls display disp Display TY options and status * disp held Display held calls help h, help List commands, abbreviations, and explanations * select sel Select originating group * clraccess clr Clear access permissions ---------------------------------------------------------------------- --------------- dug08: [D.U.G.] Directory Assistance. --------------- Two types of host directories are available to the Datakit VCS user: 1. Datakit VCS Directory - contains a list of locations, exchanges, and hosts available for access. Local Exchange Access: ENTER: "?" at the "DESTINATION: " prompt. Remote Exchange Access: ENTER: "exchange/?" at the "DESTINATION: " prompt. Example: "h/?". Remote Area Code Access: ENTER: "exchange//?" at the "DESTINATION: " prompt. Example: "mh//?". 2. Network Directory (netdir) - This is a directory service listing all systems available along with their location, exchange, local codes, system type, alternate access numbers, and contact person(s). To access: ENTER: "netdir" at the destination prompt. You will then be prompted to enter a system name. Example: "ihuxa". You may also enter "?" for more information on netdir usage. ---------------------------------------------------------------------- ------------- dug07: [D.U.G.] Terminating a connection. ------------- There are three ways to terminate a connection: a. Log off the host in the normal way. If this does not produce the "DESTINATION: " prompt, also perform the next step. b. Enter Datkit VCS command mode (see info item 'dug10') by: 1. Depressing the key on the terminal twice within one second. 2. Enter "disc" athe the DKC prompt. 3. "DESTINATION: " prompt will appear on the screen. c. Turning the terminal off after logging off from a host will also disconnect a session. ---------------------------------------------------------------------- DOWNLOADED FROM P-80 SYSTEMS.....
