UNIX Startup & AUTOBOOT Help

[drewmich]

I am doing a voice mail system repair project for a client.

The VM system is a AT&T Audix Integrated Solutions III software project interfacing with a Lucent Definity System 75 switch.

The IS 3 software has a small bug in it due to a Y2K problem that developed on 9/8/2001 - the one-billionth second after one of the main program files was originally written.

This PC based Audix VM system runs on UNIX 3.2.2.

The repair solutions start with making a date change to the UNIX system date.

I have done this fix numerous times on other IS 3s this past month but with this clients system, it starts up and loads the UNIX system software then auto loads the IS 3 program directly instead of bringing the system to a UNIX prompt first.

I need to be at a UNIX prompt to be able to complete the date rest procedures and others necessary to fix the Y2K bug issues.

I just received this IS 3 in overnight UPS Saturday delivery for a rush repair and need to get it fixed this weekend. I read the AT&T UNIX manual but can't find any easy solutions to this. I know just enough UNIX to be very dangerous but not enough to shutdown or stop the AUDIX IS 3 program from autobooting.

When the UNIX system is booting up, I need to find a way to stop the autoboot process before it loads CRON and the IS 3 software and get to the UNIX prompt.

Any help would be greatly appreciated.

When system is booting, first option is to [CTRL][D] to go multiuser or root password to enter single user mode. You probably need to be in single user. Ed Fair

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

To stop cron from autostarting you could try looking in /etc/rc2.d for a file Snncron (where nn is usually a number of 75 or thereabouts. You can rename this file (temporarily) so that it doesn't have the capital S. It will then not be started at bootup. You could also check the files in /etc/rc2.d for the startup job which kicks off the IS 3 software and rename that temporarily too. Hopefully it will have a recognisable name which you can identify by doing an ls -la command. Hope this helps.

Thanks for the help.

The main problem that I am having is actually stopping the bootup into the IS # voice mail system software.

I have tried CTRL D and other steps, but I can't get to the UNIX prompt.

Rather frustrating.

Once I get to the UNIX prompt .... I will be good to go as it is a simple date change and software re-initilize that I need to perform.

Any other ideas?

Thanks

Andrew, did you try searching for the startup script in /etc/rc2.d (or /etc/init.d, or /etc/rc3.d) at all? It's entirely possible that this isn't the way your system is set up, but if it is, it should be possible to disable the startup, edit whatever it is you need and then reboot with the startup in place again. Cheers.
