Lost /etc/passwd file
Hello,

I'm trying to recover my /etc/passwd file, but I can't make it work. Im doing the following:

1. Booting from cd-rom:
Quote:
boot cdrom -s
2. Mounting hard disk drive
Quote:
# fsck -y /dev/dsk/c1t0d0s0
# mount /dev/dsk/c1t0d0s0 /a
3. Copying my passwd and shadow files to /a/etc/
Quote:
# cp /etc/passwd /a/etc/passwd
# cp /etc/shadow /a/etc/shadow
4. Unmounting Hard disk:
Quote:
# cd
# umount /a
5. Rebooting
Quote:
# reboot
6. Stopping my OS from booting ( by pressing Stop+A).

7. Booting with -s option
Quote:
{0} ok boot -s
The Next message appears:
Quote:
Type control -d to proceed with normal startup, ( or give root password for system maintenance).
Any ideas?

Thanks in advance.

ppmtopgm

ppmtopgm(1)						      General Commands Manual						       ppmtopgm(1)

NAME

       ppmtopgm - convert a portable pixmap into a portable graymap

SYNOPSIS

       ppmtopgm [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as  input.  Produces a portable graymap as output.  The output is a "black and white" rendering of the original
       image, as in a black and white photograph.  The quantization formula used is .299 r + .587 g + .114 b.

       Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any  ppm  program  can
       read  pgm  (and	pbm  ) files automatically.  pgmtoppm is for colorizing a pgm file.  Also, see ppmtorgb3 for a different way of converting
       color to gray.  And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate  the  original
       colors, not necessarily a way that looks like a black and white photograph.

QUOTE

       Cold-hearted orb that rules the night
       Removes the colors from our sight
       Red is gray, and yellow white
       But we decide which is right
       And which is a quantization error.
