Re: Password trouble?


I think once he run /usr/sbin/etcupdate command, he didn't check (compare and merge) master.passwd file and installed standard (new and default) one. Perhaps he replaced passwd.conf file too.

After running etcupdate, you need to carefully check (at least) following files while it asks you "install (i)", "merge (m)" and "dont install (d)":

Hi all,

This might be a horrible FAQ (although some quick googling didn't  
turn up anything), but since it just happened to me and I don't want  
it to happen again...

I just built NetBSD-current successfully for the first time (yay!),
I followed the instructions from

and everything seemed great, but after the final reboot I can't get  
back into my box remotely, all passwords seem to be gone for some  
reason. :-/

Did I miss something obvious? If so, what? I hope I can fix this
from the console when I get to it later?

Something to check -- did you build with -U but install without it?
That will manifest itself as programs that should be setuid but aren't,
which in turn can cause all sorts of access problems.  Here's an easy
check: is /usr/bin/su setuid or not?  If not, that's your problem.
