I snagged a PDP11/53 and Two MicroVAX II's today at the salvage yard. $5 a
piece. Doesn't happen very often but feels good when it does.
The MV's have Ultrix on them and boot fine BUT.....
Is there an easy way to bust the root password for Ultrix on the console?
Thanks,
Brian.

Easiest way is to attach the drive to a comparable machine running
a Ultrix that you know the password too. Mount it, edit /etc/passwd,
umount it, and re-install.
You can edit the raw sector containing the root password using
console commands, then write it back out if you can fake MSCP...
Or maybe B/1 DUA0 will work... It depends if the version of Ultrix
is old enough to allow root boot without password prompt or not...

Netboot NetBSD, mount, edit, ...
NetBSD should be able to handle the 4.2BSD FFS of Ultrix.
At least it is worth a try if booting the Ultix/VAX to single
user mode don't work.

True, NetBSD would talk to it, but it would require NetBSD
running on a uVAX II so the drive could be plugged in. I
certainly don't have the patience to run NetBSD on a uVAX II,
a wouldn't recommend anyone else do the same. Unfortunately,
NetBSD (and FreeBSD) is rapidly becoming unusable on old
hardware...

You have to run it only
once to hack the Ultrix installation. Netbooted,
so you don't need to remove any drives.

I installed 4.3BSD-Tahoe UNIX on
my MicroVAX III. Currently I am trying
to build 4.3BSD-Reno from that base for my MicroVAX 3900. (Exhibition
project for the VCFE.) This is real fun. These machines feel quite zippy
with that old software. But this old stuff is real crude in some points.
NetBSD gives you a slower, but very smooth ride on this hardware.

If you want things like ssh ... you have to pay the
price.

Heh... I wouldn't expose any of my antiques to the internet... I've
got a PC running FreeBSD to take the brunt of the assault, and it
can be restored from tape in a matter of hours... The VAXen live
on their own subnet which is air-gapped from the internet unless
I really really want to ftp a file direct, in which case I power
up the hub betwixt them :)

Yes. That was one of my intentions too.
Once I got that fscked
Quasi-BSD thing installed, rebuilding real -Tahoe was reletive easy.
Getting -Reno to run is much more work. (Still struggling with libc...)

Hee. I visited the HAL2001. Big hacker meeting in .nl last summer.
I exposed my PDP 11 running 2.11 BSD to the net with > 3000
hackers^W script kiddys around. It was not hacked. I asume nobody
of that script kiddys knows today what a PDP 11 is. :-)
There are still some other things independent to networking that may
be show stoppers for "modern" software. No mmap(2), only K&R C, ...

I don't think you can write to an UFS from NetBSD. At least
with FreeBSD I can read but not write. But the easiest way to
recover lost unix passwords is to boot in single user mode
and then change password the normal way. Consult your VAX
manual for the boot parameters for single user mode.
