I'm posting this for a friend. Someone he knows has a AT&T PC7300 running Sys V Rel 3.0. On it, they have an accounting package and a db package - I dont know who makes them. The persons they got the system from went bankrupt, and left town. Now they are having problems. The only two ids on the system take you into the packages, and no one there knows the root password. The packages do not offer a way out to the OS. Its simple, they cannot log onto the machine other than through the package ids. I remember from an ATT course that if you somehow forgot your root password, that you could shutdown and reboot from a floppy (a diagnostic, or field service one if I remember correctly), and that the floppy contained a routine that would let you reset your root password. I'm foggy on this, because I have a Vax 8600 running sys V, and I cant do this on my machine. Well, have I been dreaming or what? Anyone know of a way to get to the shell level on this machine - by the way, they have no manuals, and no floppy. Any suggestions as to what these people should do, or someone they could contact within ATT for help would be appreciated. Please post (or email if you are concerned with security). Thanks in advance. Calvin Hayden Texas Instruments, Johnson City, Tn. Voice (615)461-2254 UUCP: ...mcnc!rti!tijc02!{root,cgh018}

Without going into a lot of details, here is the basic idea: 1) Boot the system from the "Floppy Boot Disk" from the foundation set. 2) When it prompts for the "Floppy File System," insert the disk and hit return. 3) When it asks the next question (something like "Do you really want to initialize your disk?"), hit DEL. 4) You will be at a shell prompt with the hard disk mounted on /mnt. 5) Use /mnt/bin/ed to edit /mnt/etc/passwd. 6) Don't forget to "umount /dev/rfp002" before rebooting. -- Peter Fales AT&T, Room 5B-420 N9IYJ 2000 N.
