-
- Example Scenarios
- -----------------
-
- LAN HIJACK for Network Support
- Jack's in his new spread sheet program and can't remember how to
- generate a 3D bar graph. So he presses the LAN HIJACK HELP HOT
- KEY. Jill, the company spread sheet guru, is writing up a letter
- in her word processor when her computer sounds the LAN HIJACK help
- alarm. She presses the LAN HIJACK HOT KEY and then the F2 key,
- and instantly she is in jack's spreadsheet. With a few keystrokes
- she whips out the graph, then HOT KEYS right back to her letter.
-
- LAN HIJACK for Sharing Hardware.
- Jill needs to FAX out her letter. But the FAX board is in the
- computer downs stairs. So she presses the LAN HIJACK HOT KEY and
- "hijack's" that station. Then runs up the FAX program and sends
- the FAX. Then HOT KEYS right back to her word processor.
-
- LAN HIJACK for Training Seminars
- Jill needs to train her staff on their new accounts receivable
- software. So she hosts a LAN HIJACK conference. From her station
- she steps through the tricky parts of entering a receivable. And
- all of her staff can watch her from their work stations.
-
- LAN HIJACK for MultiProcessor MultiTasking
- Jack has to print out several reports before he can leave for the
- night. Instead of waiting for his station to print the reports
- one at a time, he "hijacks" another station and starts it printing
- one report. Then "hijacks" another station to print another
- report. And on and on, using all available stations on the
- network to work on his job. All at the same time! With LAN HIJACK
- the full power of your network is available at your station.
-
- Key Features
- ------------
- Wide Area Networks
- On your wide area network you can hijack a station next door or
- across the country!
-
- Conferencing
- You may hold network conferences. Where many local work stations
- can join a conference and watch your display.
-
- Security Controls
- Novell's security system determines which users may "hijack" a
- station. And which stations a user may "hijack". All security is
- assigned using Novell's SYSCON utility.
-
- Easy to Use
- Selection and control of another station is intuitive and simple
- to learn.
-
- Keyboard Lock Out
- When you "hijack" a station you may lock it's keyboard, giving you
- exclusive use of that station.
-
- VGA and Hercules Graphics Support
- Supports all VGA and Hercules Graphics modes. And you can
- "hijack" stations with different display adapters.
-
- Help Alarm
- Users can call for assistance by pressing the HELP HOT KEY.
-
- Memory Resident
- Both sides of LAN HIJACK are memory resident, using just 5 kbytes
- in the remote station.
-
- Removable
- The memory resident portions of LAN HIJACK can be removed from
- memory without rebooting.
-
-
-
-
- THE LAN HIJACK PROGRAMS
- -------------------------------------------------------------------------------
-
- LAN HIJACK uses two memory resident programs, LH.EXE and LHR.EXE.
- When you run either program from the DOS commandline they are then
- "loaded" and return the DOS prompt immediately. Once loaded, to
- activate the program you must press a HOT KEY combination. You
- select the HOT KEY combinations when LAN HIJACK is installed.
-
- When LHR.EXE is loaded on a station, then the station can be
- "hijacked" and controlled by another station. However, the
- station can not "hijack" other stations.
-
- When LH.EXE is loaded on a station, then the station can "hijack"
- and control other stations. However, the station can not be
- "hijacked" by another station.
-
- When both LHR.EXE and LH.EXE are loaded on the same station, then
- the station may "hijack" other stations and the station can be
- "hijacked" by other stations.
-
-
-
-
- REQUIREMENTS
- -------------------------------------------------------------------------------
-
- A Novell Netware network with PC/AT/PS2 work stations or close
- compatibles.
-
-
-
-
- INSTALLING LAN HIJACK
- -------------------------------------------------------------------------------
-
- The LAN HIJACK install program will configure LH.EXE and LHR.EXE
- programs and place them in a selected destination directory. You
- must use the install program. And you can only use the configured
- LH.EXE and LHR.EXE programs placed in your destination directory
- by install. Install will also create a user group, called
- LAN_HIJACK on your network.
-
- To install LAN HIJACK complete these steps:
-
- 1. Login to your network as SUPERVISOR.
-
- 2. Insert the LAN HIJACK diskette in any drive.
-
- 3. Complete the install program. For example, if the diskette
- is in drive A, then from the DOS prompt type:
-
- A:INSTALL
-
- 4. Remove the LAN HIJACK diskette and save it.
-
- 5. Run Novell's SYSCON to add LAN HIJACK users to the LAN_HIJACK
- group. Only add users who will be permitted to "hijack"
- other stations. For assistance in using SYSCON refer to your
- Novell Netware manuals.
-
- 6. For each work station that will use LAN HIJACK you should add
- the LAN HIJACK programs to the station's boot diskette ( or
- diskless boot file ), as follows.
-
- If the station will be used as a remote, copy the LHR.EXE
- program from your destination directory to the boot diskette.
- And add the command LHR to the boot disk's AUTOEXEC.BAT file,
- just after the NET? command. Note, if the station uses
- XMSNET? or EMSNET? use XMSLHR.EXE program in place of
- LHR.EXE.
-
- If the station will "hijack" remote stations, copy the LH.EXE
- program from the destination directory, to the boot diskette.
- And add the command LH to the AUTOEXEC.BAT file, after the
- NET? command. If the station is to have both LHR and LH
- loaded, then LHR must be loaded first.
-
- 7. Reboot each work station to load the LAN HIJACK programs.
-
- LAN HIJACK is now ready to use on your network.
-
-
-
-
- USING LAN HIJACK
- -------------------------------------------------------------------------------
-
- LAN HIJACK can be used on any station that has loaded LH.EXE. And
- the user currently logged in at the station must be a member of
- the LAN_HIJACK group.
-
- To invoke LAN HIJACK press and hold the hot key combination you
- selected during installation until your computer beeps twice. In
- a moment the LAN HIJACK screen will be displayed.
-
- Selecting A Remote Station
- --------------------------
-
- From the LAN HIJACK screen you may press either the up or down
- arrow keys to select a remote station. If the selected station
- has a user logged in, the user's login name will be displayed.
-
- Or you may browse through your network with the left and right
- arrow keys to select a remote station. Here however each remote
- station's display will be shown on your screen.
-
- Once you have selected a remote station you can "hijack it", that
- is connect to it and take control, by pressing the ENTER key. You
- can now use the station.
-
- To return to the LAN HIJACK screen press the LAN HIJACK HOT KEY.
- You may select another station or exit LAN HIJACK, by pressing the
- ESC key, and return to your station.
-
- The Function Keys
- -----------------
-
- While you are not connected to a remote station, you may use the
- following function keys.
-
- F1 Returns you to the LAN HIJACK screen while browsing.
- F2 Select the station that requested help.
- F3 Lock the selected station's keyboard.
- F4 Unlock the selected station's keyboard.
- F5 Turns keyboard intercept on.
- F6 Host a Conference from your station.
- F7 Join a Conference.
- F8 Send a broadcast message to station.
- F10 Exits LAN HIJACK.
-
- Some of these functions are explained below.
-
- Keyboard Intercept
- Some programs take control of the computer's keyboard so that
- remote key strokes will not be received. Invoking keyboard
- intercept may remedy this problem. Intercept is turned off
- automatically when returning to the LAN HIJACK screen. For
- example, try Novell's NSNIPES game. Hijack a work station and run
- NSNIPES. You will find that the station does not respond to your
- key strokes. So, press the HOT KEY combination, to return to the
- LAN HIJACK screen. Then press the F5 key and the ENTER key. You
- can now play the game.
-
- Conferencing
- You may share your display with others on your network via
- conferencing. To host a conference, press the F6 key from the LAN
- HIJACK screen. You will then exit LAN HIJACK and your display
- will be available to all stations that join the conference. Any
- other station on the local network can join the conference by
- pressing the F7 key from their LAN HIJACK screen. When joining a
- conference there are no station restrictions. To end a conference
- just press the LAN HIJACK HOT KEY combination. Note to host a
- conference you must have both LH and LHR loaded. And conferencing
- work stations must be on the same local network.
-
- Program Removal
- ---------------
-
- You may remove both LAN HIJACK resident programs with the -r
- commandline option. For example, at the commandline type either:
-
- LH -r
- LHR -r
-
- Display Compatibility
- ---------------------
-
- When LAN HIJACK is used between two computers with different
- display adapters, LAN HIJACK makes a best attempt to translate the
- display. There are some combinations of display adapters and
- modes that are not translatable. In these cases LAN HIJACK will
- display the message "Display mode Not Supported." Here you still
- have control of the station's keyboard but can not see the screen.
-
- User Restrictions
- -----------------
-
- To use LAN HIJACK you must be a member of the group LAN_HIJACK. A
- user who is NOT a member of the LAN_HIJACK group can NOT activate
- LAN HIJACK and can NOT "hijack" any stations. To add or change
- users to the LAN_HIJACK group use SYSCON ( refer to your Novell
- manuals ).
-
- For example, you may want to be the only person able to "hijack"
- other stations. Here you would make yourself the only member of
- the LAN_HIJACK group.
-
- Station Restrictions
- --------------------
-
- LAN HIJACK adheres to Novell's stations restrictions for each
- user. So that a user can only "hijack" a work station if the user
- has login privileges to that station. To change station
- restrictions use SYSCON ( refer to your Novell manuals ).
-
- For example, you may have a modem in one work station that you
- want everybody to be able to "hijack". But you do not want just
- anyone to "hijack" your station, or the "boss's" station, etc.
- Here you would add station restrictions for each user. Each user
- must be given station restrictions to their own station and the
- station with the modem.
-
- LAN HIJACK and WINDOWS
- ----------------------
-
- With WINDOWS in REAL mode you may freely "hijack" and be
- "hijacked". But control of the remote mouse is not possible. You
- may "hijack" a remote station running WINDOWS in STANDARD or 386
- modes, but can not control the remote keyboard. And when running
- WINDOWS on your station in STANDARD or 386 mode, you should NOT
- enter LAN HIJACK via the HOT KEY, instead run LH as a DOS
- application with the Non-resident commandline option. ie. LH -n
-
-
-
- TROUBLE SHOOTING
- -------------------------------------------------------------------------------
-
- This trouble shooting appendix explains some commonly encountered
- problems and their solutions.
