I'm told you should contact your distributor for a replacement.

Subject: / password for image Base-3.0-1.tar.gz

I attempted to put a fairly simple base system on a spare partition, 
to use if (when) I hose my primary root filesystem - I used the image 
Base-3.0-1.tar.gz, which appears to work, but apparently doesn't use 
vnc as the root password . . . any clues?

Either that, or my authentication isn't working right, 'cause I can't 
login in the way it is now.  Fortunately, I did this without wrecking 
any other partitions, so I can still work.

Should be vnc

You can always use the firmware to launch a shell as init:
  boot cmd=init=/bin/sh
Then change the password:
  # mount -n -o rw,remount /
  # >/etc/mtab
  # mount -f /
  # mount -a
  # passwd root
  # umount -a
  # sync
  ctrl-alt-del

Good luck.

One thing.  ctrl-alt-del will not do what you expect it to do, as init is
not running.  It will simply reboot the system, without umounting the file
systems first.  (at least I'm 99.3475% certain about this fact :)).  You
might want to umount your, non-root, filesystems then:
	mount -n -o ro,remount /

As well instead of "mount -a", you might simply want to mount /usr (if it
is not on your root partition)..

Sorry Rod, it does EXACTLY as I wanted it too.  Tested before I posted.

You are 100% correct...but read my message again and notice "umount -a".

What do you think "umount -a" does? :)

"mount -a" is shorter to type.

As an apology, you can buy me lunch today :)

picky, picky  Didn't see the "umount -a"...

Ok, but the last sync is redundant.  If you want to sync, you should do it
before you umount the file systems, or mount them read-only.  Syncing on a
read only file system doesn't really have any effect does it?  So you could
save an extra 5 key strokes.  Unmounting a file system should flush all the
buffers anyway, same with remounting it read-only.

> As an apology, you can buy me lunch today :)

I don't know, those 5 key strokes were expensive I think :)

sync is an old habit (from other *nixes) that isn't a bad thing...especially
when people like you miss the "umount -a" :-P

Don't make me come over there!

Well, now that y'all have resorted to fist-a-cuffs, I'll pop back 
in and thwack myself . . . I managed to get the kernel loaded from 
the new partition with the "base" image, but I was still mounting 
my old root file system . . .

My Netwinder doesn't get a response from the MediaOne DHCP server.  I've
tried everything I can think of.  I'll give US$50 to the first person
who helps me solve this problem.  For full details go to:

Subject: Re: DHCP and cable modem (REWARD!)

Hi Mike,

MediaOne keys their DHCP servers to your Ethernet address.
Therefore, you must use the same ethernet address as the Win98
system or M1 will not answer your DHCP requests.

I see that you have,
                               WIN98                  NETWINDER
CLIENT HW ADDRESS:             00a0cc3b9980           0010570008cd

Luckily you can change the Ethernet address using ifconfig,
Try this,

# /sbin/ifconfig eth0 down
# /sbin/ifconfig eth0 
# /sbin/ifconfig eth0 hw ether 00:a0:cc:3b:99:80
# /sbin/ifconfig eth0

and see if the HWaddr field changes.  Then try running
your dhcp client

# /sbin/dhcpcd eth0

(I'm assuming your using the 10mbps port to connect to the cable
 modem, and saving the 100mbps eth1 for your LAN).

I actually have a (probably outdated) page about this,
  http://www.netwinder.org/~guinan/m1x.html

I moved a few months ago, and unfortunately the town-run cable co. 
is not quite ready with their cable modem access ("any day now") so
I haven't tried this lately.

Let me know if I can help further.

- -Jamie

p.s.  
Keep the money, or donate it to the FSF if you really want
to get rid of it.  :)

From: Ralph Siemsen <[email-masked]>
Subject: Re: DHCP and cable modem (REWARD!)

Hmm, I don't like the implications of your findings at all.  Hardcoding
the mac address in the modem is *very bad*, and if MediaOne is forcing
it upon you, then they should be shot.  Hardware manufacturers are under
strict obligation to ensure that mac addresses are *unique*; if your isp
requires you to override that setting, then they undermine the whole
process.

I have a cable modem on @home, which also recognizes only one mac
address at a time.  However, it is not hardcoded, I just power-cycle the
modem and it picks up the address of the ethernet card in my winder/pc. 
The Rogers service has other DHCP problems we are aware of (they require
specifying the hostname in the vendor options field of the DHCP packets,
and none of the regular pump daemons do that - we've patched the daemon
for this - /users/d/douglasp/redhat/RPMS/ for anyone who needs it).  The
upcoming officeserver includes this version and has support in the GUI
for entering the DHCP hostname... if we have to support mac address as
well, I hate to think how many more extra fields I might end up having
to put in!
