password failure- after mergmaster
OOOPSS- I got mergemaster to run- but now that the system restarted the root password and my password are invalid- I can ONLY start in single user mode- I still do have level 0 dump of 5.4 on my network is this my only option ?

It's always wise to back up /etc before running mergemaster to cover just this type of mistake. In this case I'm guessing you replaced your /etc/master.passwd with the default one. From single-user mode, set the root password using the passwd utility. You will probably need to re-add your user account and any others that aren't part of the system default. I would grab /etc/master.passwd from your backup and do a line-by-line comparison with the file currently installed on your system. When re-adding users, be sure to use the same UID's and GID's so that file permissions will be correct. See man pw for details. Alternatively, you could replace /etc/master.passwd with the copy from your backup and run mergemaster again. This time pay attention and actually merge the file.

If you did upgrade you can do a restore from your dump, and try again. Or just check or reset the root password in single user.

Note that there will be a backup copy of the master.passwd file in /var/backups/master.passwd.bak -- the will be possibly more than one backup copy in that directory. These are created by the nightly periodic script: /etc/periodic/daily/200.backup-passwd which is enabled by default. As these run overnight the backed-up copy should pre-date your adventures with mergemaster. Verify that the contents are sensible, then copy it back to /etc/master.passwd and run pwd_mkdb(8) to generate /etc/passwd and /etc/pwd.db from it.

Have to *merge* the changes into /etc/master.passwd rather than brute force overwrite. Notice the difference from my first post in this thread, the file which was clobbered is /etc/master.passwd, not just /etc/passwd which is a dummy file generated from master.passwd. In single user he can mount -a to get all the filesystems mounted read/write, then extract /etc/master.passwd file from his level 0 dump. But once again it needs to be diff'ed against the new version written by mergemaster to see why mergemaster changed it. Then the password databases need to be rebuilt. The easiest way (and only way I remember without manpage surfing) is to run vipw and trivially change the master password file. On exit vipw rebuilds the password databases with pwd_mkdb(8) (I had to look that up). -- David Kelly N4HHE, [EMAIL PROTECTED] Whom computers would destroy, they must first drive mad. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Two, you really should learn how to perform an update and/or recover from system problems if it doesn't boot by working on a test system first, and only making significant changes to a production system once you've gotten confident you know what you are doing. Failing that, perhaps you ought to hire a sysadmin or consultant with decent BSD experience, and let them solve the issues so that you can focus on other things -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Thanks David, that's indeed my point: FreeBSD comes packed with tools, among them are tools to create (or to delete) user accounts. Those tools can easily be scripted.
