lost root account
Hi there, I have inherited an openBSD machine with no root account. When I boot up in single user mode boot -s and do a cat /etc/master.passwd | root the only thing I get is: daemon:*:1:1::0:0:The devil himself:/root:/sbin/nologin I can't seem to make changes to the master.passwd account by using vipw in single usermode. I get a message that the file is locked or busy. Can anyone help in what I can do next? How can I add the root account back to the master.passwd file. thanks.

Re: lost root account
Boot your machine in single user mode (boot -s) and use plain vi and pwd_mkdb soon after that. There's no need to use vipw when running in boot -s.

Re: lost root account
Hi Marcus, I thought it was enough to add the root account through vipw. that this edits the master.passwd file and would automatically update everything else? how would I use pwd_mkdb, i don't want to delete any other accounts from the master.passwd file. thanks Date: Mon, 19 Nov 2007 17:41:01 -0200 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED]; misc@openbsd.org Subject: Re: lost root account Boot your machine in single user mode (boot -s) and use plain vi and pwd_mkdb soon after that.

Re: lost root account
thanks Juan, faq8.1 shows me how to reset my root passord but i could not find anything on recreating the root account. Perhaps I am missing something?

That's the lock file which apparently exists on the machine for some reason (i.e., someone was sitting in vipw when you powered down the machine). /etc/ptmp isn't documented in vipw (it probably should be), but it is covered in passwd(1). It should also be documented in faq8.html, I'll try to fix that this evening. :) Nick.

Re: lost root account
Ok the issue was solved! mount -s -uw / vipw I typed the missing root account line back in and saved the file and can now log back in as root. this then invoked pwd_mkdb to do all the rest. thanks everyone. only issue now is that if I try to change another users account password I get the following: enter: passwd username enter: new password get: pwd_mkdb: corrupted entry pwd_mkdb: at line #24 pwd_mkdb: /etc/ptmp: Innapropriate file type or format passwd: etc/master.passwd unchanged Do you have any idea what could be causing this, the user entery in master.passwd looks fine.
