Re: new NetBSD user dummy questions - change root password problem

[Supernobby <supernobby%gmx.net@localhost>]

Hi Radek,
the file /etc/passwd.conf only contains comments (all lines start with '#'). 
So I guess some default cipher is in use. Do you know what is the default?
The file is prepared for "md5":

#default:
# localcipher = md5
# ypcipher = old

But md5 seems not the default. Because when I uncomment this and use md5, 
pwhash gives different output. And passwd command will also not work.

If I use passwd -d files the error is a bit different:

###################
passwd: Couldn't generate salt: Invalid argument
passwd: /etc/master.passwd: unchanged
###################
Is there some tool not installed or missing?!?

Again, if I just use passwd command, I get:

###################
Couldn't get salt.
Unable to change auth token: error in service module
###################

I also did the test with pwhash and used vipw to insert this output in passwd 
file. And this worked. The username I used can now login only with password.

I also managed to install the BFFS filesystem on AMIGA side. So here is the 
current /etc/passwd:

#########################

Thanks very much for your efforts!
Bye,
Andreas
