single user mode - user accounts passwords
Post 65812 by Perderabo on Wednesday 9th of March 2005 08:54:03 AM

Ahem, another "relic" checking in here... 
The NCR Tower ran AT&T System V, not Xenix. You need to keep that ADDS terminal since the software needs to run curses based programs with a limited number of supported terminal types.
It's been almost 15 years since I've seen an NCR Tower and I don't remember enough about them to be helpful. However I have a TOWER 32/8XX Support Student Manual dated 1989. It is very terse, but I might have a procedure that may work. You will need an OOS tape to do it. These instructions are for Release 010100 by the way.
"Press the RESET button on the System Control Submodule on the Master AP." I seem to remember opening a door to expose all of the cards to reach this switch, but I'm not sure.
You should get a menu "Select Start-Up Function". Select "1. Load". You will be asked for the load device and you need to use "st00". You should now see a "System Loader Functions" menu. Select "5 Load Out-of-Service System". This should give you a list of terminal types. Pick yours.
You should get a OOS menu. I think "3. Service Utility Shell" is the best choice. You want to get to a bourne shell prompt. Now you need the name of the root disk. If you don't know, try the default:
mount /dev/dsk/10s1 /mnt
Now you need to fix /mnt/etc/passwd to change or remove the root password or create a root equivalent account with no password.. Exactly what you do depends on what programs you have available and I don't know what you have at this point. Any unix expert should be able to take it from here. Good luck.

ugweb - starts the HP-UX User and Group Account Configuration tool SYNOPSIS
[ ] [ ] DESCRIPTION
The HP-UX User and Group Account Configuration tool ( ) is used to manage user accounts and group accounts on the local system. This tool can also be used to manage user accounts on a NIS system. The HP-UX User and Group Account Configuration tool provides both Web-based and terminal user interface. The Web-based interface is launched through the HP System Management Homepage. Superuser privileges are required to access the HP-UX User and Group Account Configuration tool. A user who does not have superuser privi- leges has read-only access to the Local Users, NIS Users and Groups areas in the HP-UX User and Group Account Configuration tool and cannot modify local user accounts, group accounts and NIS User accounts. An attempt will be made to connect to a Mozilla/Netscape Web browser running on the X server defined by the DISPLAY environment variable. If a running Mozilla/Netscape client is found, it will be used, otherwise a new Mozilla/Netscape session will be initiated. This will only happen if the Mozilla/Netscape process is running in the same system as that referenced by the DISPLAY variable, unless the -F option is used. Note: By default, the HP-UX User and Group Account Configuration tool (ugweb) invokes the Mozilla Web browser. If you want to support any other browser (Netscape), set the $BROWSER environment variable as shown below: The terminal user interface is invoked if any of the following conditions are true: o The command is invoked with the option. o The environment variable is not set. The Web-based interface is launched if all the following conditions are true: o The command is invoked with option. o The environment variable is set. o The command is available on the system. If the Web-based interface cannot be launched, invokes the terminal user interface. Options recognizes the following options: Forces a client browser to be used in less secure ways. The option forces the client browser to be used or started, even when the X-traffic between the X-server and the Mozilla browser is not secure. Use this option only when you are sure the network traffic between the host where Mozilla is running and the host in the DISPLAY variable is secure. If cannot start the Web browser, the terminal interface is started. When the HP-UX User and Group Account Configuration Web interface is invoked by SMH, the option is used. If a privileged user (root) executes the command with the option, a temporary login bypass key is generated. The bypass key enables the user to access the Web interface without having to provide login information again. When the HP-UX User and Group Account Configuration interface is started by SMH, the option is used. Launches the terminal interface for managing local users, NIS users and groups regardless of the current setting of the environment variable. You can also start the HP-UX User and Group Account Configuration tool using one of the following methods: o Run and select the Accounts for Users and Groups to launch the tool in Terminal User Interface mode o Start the HP-UX User and Group Account Configuration tool Web interface by typing the URL in the address bar of your browser, where hostname is the name of the server o Launch the HP-UX Systems Insight Manager on the server and select the User and Group Account Configuration tool from the Config- ure -> HP-UX Configuration menu Online Help After the HP-UX User and Group Account Configuration tool is started, the online help provides details on how to use the tool.
