passwd files (solved sort of)

[Mike Cantrell]

Hmmm.. I wonder if there are any security implications in doing so. SCO's
shadow file is highly specialized for it's OS not to mention the special
accounts each system has. While it might allow them to log in, etc.., it
might end up giving you a headache in the long run.

I'd restore the original files, copy the shadow and passwd files to /tmp on
the linux box and run this script (I'm bored... very bored). You'll want to
make sure the start_uid variable is what you want. Most SCO system's regular
users start at 200 but you'll probably want to double check.

(depending on where your perl is installed, you may need to change the 1st
line to point to the location of your perl executable)

#!/usr/bin/perl
use strict;

my $passwd = "/tmp/passwd";
my $shadow = "/tmp/shadow";
my $start_uid = 200;

open(PASSWD, $passwd) || die "Can't open $passwd: $!";
open(SHADOW, $shadow) || die "Can't open $shadow: $!";

my @users;
PASSWD: while(<PASSWD>) {
    my @passwd = split(/:/, $_);
    my $user = $passwd[0];
    my $uid = $passwd[2];
    while (<SHADOW>) {
        my @shadow = split(/:/, $_);
        if ($shadow[0] eq $user) {
            my $crypt = $shadow[1];
            push(@users, { user => $user, uid=>$uid, crypt=>$crypt});
            next PASSWD;
        }
    }
}

foreach my $user  (@users) {
    if ($user->{uid} >= $start_uid) {
       print "useradd $user->{user} -p $user->{crypt}\n";
       system("useradd $user->{user} -p $user->{crypt");
    }
}
