People here in South Jersey still leave their doors and cars

- Dan.
They leave doors and cars unlocked in rural NH also. For the whole 8+ 
years I've known him, my BF (who, incidentally, was originally from 
South Jersey but had escaped from NJ about 10 years before I met him) 
has never locked the door to his house, and only occasionally his car or 
truck -- and that was only when he was visiting me in my Sewer Rat Nest 
and I taught him he had to, at least when he was visiting ME (in 
Elizabeth NJ, where I lived for 25 years until I finally escaped from NJ 
too, with his help -- yes, horrors but I can admit it in public, now 
that I don't live there anymore).


Well, my city dwelling Sewer Rat tendencies from a quarter of a decade 
in the Sewer are such that I am a habitual door locker (i.e., apartment 
and car),  the kind who actually checks to make sure I locked the 
apartment or car, whichever applied at the time, when 
over-stressed/spaced out. In fact, soon after my escape (to a small town 
in NH) I :blush: accidentally locked myself out on the upstairs 
porch this winter when it was in the teens and had to stay out there for 
over an hour until a neighbor could rescue me.  :blush:


Ah well. Now about that wi-fi security thing. I read the article Bruce 
linked to, and this was the first I had heard of innocent people being 
accused of downloading child porn because some pervert used their 
non-secured wi-fi connection to download it. I WAS familiar with the 
concept of the 32% of all people have tried to access other people's 
wi-fi networks thing, though, because, I will admit, when I originally 
got my iBook (summer 2007) which had Airport, and found that networks 
were showing up when I sat in my living room with it, I was occasionally 
an opportunist. Translation:


98% of the time I used my own Internet connection (dialup until I 
finally got DSL in the fall of 2009). However, every so often if I was 
on the iBook, I would try to join networks it detected just to see if I 
could. If they were secured (i.e., I got a prompt asking for a 
password), that was the end of my attempt on that network. If it wasn't 
secured and I got right on, yeah, I would use it for a few minutes. Not 
for child porn though. LOL I would use it to peek around on some of my 
Sims forums just amazed that I was able to do it at all (not to mention 
wowed by the high speed), and was too lazy to go back in the bedroom on 
the Quicksilver to use my legitimate Internet access.


BUT, and now comes the dicey part. After a few months, I had managed to 
remember the names of the secured networks and which ones I could get 
on. So occasionally on one of the monthly Sims contests I would 
participate on at some of the forums, I began to get on the iBook and 
borrow half an hour to maybe an hour or so to upload Sim pictures 
(challenge/contest entries) to my Photobucket account (or look at the 
other entries posted by my competitors on THEIR Photobucket accounts). 
That used to take me literally DAYS on my dialup account; I only had the 
patience to spend 3-4 hours at a time waiting for my uploads to go up or 
to see all the other Simmers' pictures, and I would need to upload (or 
look at) 25-50 Sim pictures per challenge/contest entry. So it would 
take me anywhere from 3 days to a week to upload my pics/look at others 
on my dialup connection, compared to an hour or maybe a little less if I 
borrowed a little wi-fi. So yeah, I used to do that (and no, none of 
us had any naked or otherwise inappropriate pictures of Sim children!).


Obviously, when I finally got DSL in 2009 I didn't need to do that 
anymore, and in fact, since my BF gave me a router, I was able to have 
my own little network and go online in the living room with the iBook's 
Airport legitimately. Now back then I was quite deliberate in not 
securing my network -- I had, after all, occasionally borrowed wi-fi 
from neighbors, and I honestly felt that leaving mine open would be 
returning the favor to some other neighbor who was still in the 
position I had only just gotten out of -- stuck on dialup, unable to 
afford high speed Internet.


As time went on -- a few months to almost a year -- I noticed (from my 
iBook's Airport) that networks were disappearing -- both ones I 
remembered as secured as well as the ones I used to borrow from, and 
the new ones slowly coming in,

 I have recently bought an iMac G4 (iLamp) off craigslist-it's the

Just an aside, as your main questions have already been addressed by
others...

There were two extremely similar models of 800MHz G4, 17 iLamp.

The first one will boot into OS 9.2.  The second one will not.It's
a bit like the difference between a regular MDD and a FW800 MDD,
except harder to tell apart.

Yours is probably the first model, as it came with an 80GB hard drive,
and the later, OSX only model, came with a 60GB hard drive.   But hard
drives can be changed.

The clear distinguishing characteristic is that the OS 9 booting model
has NVIDIA GeForce4 MX graphics and the OSX only model has NVIDIA
GeForce2 MX graphics.

Probably not important to you, but a bit of iLamp trivia which is easy
to overlook.   Most of the folks selling them on Ebay don't seem to
know which model they have, or even that there are two nearly
identical models with such a significant difference in capabilities.

I had forgotten that the G4 iMacs were updated once before they added 
USB 2, thanks for the reminder.


According to Mactracker both of the USB 1 17 iMacs use the GeForce4 MX 
but the earlier one came with 32 MB of VRAM whereas the second one came 
with 64 MB VRAM.

Router: US Robotics MAXg, Model 5461.

Computers:

1. G4 Quicksilver 867. Tiger 10.4.11. This is the one I use the most to
go online. It picksup from the downstairs router using a  Belkin 54g USB
Network Adapter/Ralink Wireless Utility driver, version 1.2.8.0u. (Note
to Kris Tilford: I saw your posts about this awhile back, but I didn't
then, and still do not need or want to upgrade it.)

2. G3/800 iBook. Tiger 10.4.11, has built in Airport. I use this to go
online a lot and may soon possibly be using it online as much or more
than the QS.

3. G4 1.5 GHz Mac Mini. Tiger 10.4.2. I usually don't go online with
this machine (it's my dedicated Sims Box), but it does have built-in
Airport and on infrequent occasions I do pop open Dashboard (to look at
the weather widget) or Safari for a quick informational surf to a Sims
forum.

4. My BF's work PC laptop (running Windoze XP) also needs to be able to
occasionally join.

There is also a small but definite possibility I may play with trying to
get my pre-OS X Macs in on it, so it would be NICE if this would work
between 7.5.5 and 9.2.2.


If you download the manual for your router it should have instructions 
for password protecting your network (or maybe you have a printed manual?).


IIRC the classic Mac OS' only support 802.11b and WEP encryption, which 
as previously mentioned is less secure than WPA but better than nothing.

USR has a nice easy-peasy tutorial here:

Just select the defaults of WPA2 and WPA (PSK), and TKIP  AES.

Choose a good passphrase mixing letters and numbers: Hey it's sn0w1ng 
Macintoshes outside!

Voila' all done. 

Now on each of your macs and pcs tell them to forget the connection and 
re-establish it, entering the passphrase as above.

Your old OS 9 machines may work, but 8 and 7 probably not. Use a wired 
connection for those. It means you need to be within about 100 meters (cable 
run) of the router. Unless your name is Trump, this is a limitation you're 
unlikely to reach in the typical dwelling :-)

It doesn't have to be complex. Using a random generator such as RPG and
an *encrypted* password repository such as Pastor, PasswordWallet,
Keychain Access, 1Password, etc… provides good security without having
to resort to memorizing or writing them down.

Granted Pastor's RC4 encryption algorhythem isn't the strongest in the
world, but it is free and should be sufficient unless you are trying to
protect national security data.

  IMO EveryMac.com gives more  info than Matracker on all the Macs.
According to EveryMac.com Jeff's explaination is spot on.


I agree that EveryMac has more information, I just find a local

Of course now it's a matter of determining which database is correct.

 I have Mactracker too but for in-depth and more models I use  
Everymac daily and it seems to be updated by the minute In fact I can  
use it for a lot of info Apple keeps close to home, such as RAM specs

recall him grumbling about WPA2 and being pissed off saying I thought 
I read somewhere that Tiger DID support WPA2! or something like 
that...and there was some PITA crap he had to go through so he could use 
his own wifi, and my iBook's Airport will NOT join his brick wifi when 
I'm at his house unless he gives me this dongle-ish thingie to plug into 
one of the USB ports (and my iBook DOES have 10.4.11 on it). Well, 
that's why I don't want to taste any of the various flavors of WPA. OK,

instructions at the US Robotics site on how to set up WEP, and it even

To repeat for what it's worth, you simply can NOT permanently lock
yourself out of your network. The worst you can do is forget and lose
all the router passwords and need to go through the hassle of
resetting the router back to the factory defaults so you can go redo
the entire configuration process for the router and all your systems.
Extremely tedious, yes. A bricking of the router, no.

In the more likely scenario where you remember the admin password to
your router you can just plug an ethernet cable into your router (if
you haven't already) and then logon to router and change the Wi-Fi
security password to whatever you like. Again, tedious and annoying
but no more than that.

As long as you have physical access to your router you can always
configure it, one way or another. So don't worry about more than a
potential temporary lockout as a worst case scenario.

WEP is better than nothing. But it is just a screen door. Most folks
are either polite or easily discouraged and so won't breech a screen
door which is what Bruce's rational is counting on. But if you have
both a screen door and metal door with a security lock why not use the
stronger one? Why even bother with the one in a million risk of
encountering someone with no manners? I'm just sayin' ...

Of course, the other reason to use WPA2 is for those using 802.11n,
which is NOT the case here. The reason you would want to use WPA2 with
AES encryption with 802.11n is because if you don't then the  protocol
requires the router to limit the connection to 802.11g speeds. Or at
least that's what I've been told. Seems a rather odd requirement to
me, but it also strikes me a foot pushing on the butt attempt to
move people to a better security protocol.

Re: iMac G4 questions

Thanks for all the insight... now I'll have to check and see what
GeForce it has!! ;-) This screen has plastic on the top as far as I
can tell, the shame is all the pixels are nice and bright, only the
top layer is scratched. Might just have to keep an eye out for dead
iMacs with good screens.

As for the hard disk, out of curiosity, does anyone know if OS X
refuse to boot on SMART errors? My PCs never hesitate... maybe OS X
takes the safe route and kernel panics.

Ralph, this hard disk was pretty easy to get to: I just removed the
motherboard, and the disks were right there in a caddy. See xlr8 your

A couple of useful hints and a tale of my day...

2011-04-26 Thread Bruce Johnson
How to open a finder window as root:

http://yourmacguy.wordpress.com/2009/09/28/snow-leopard-root-finder/ 10.6
http://yourmacguy.wordpress.com/2009/07/31/finder-with-root-access/ 10.5 and 
lower

Saved my butt today, fixing a department head's munged Powerbook...something 
ate his home directory, he could log on, but then it went to the background and 
nothing else ever appeared: no dock, no Desktop, etc.

FORTUNATELY (HINT HINT!!!) there was another user account with Admin privileges 
already present on the computer. I was able to log in as that user.

Here's the fix, if you ever find yourself in this situation.

Applejack found most or all of the missing pieces of his user directory 
structure and put it in /lost+found as a long series of numbered folders 
523343, 512244, etc etc..

(See:

http://www.techworld.com.au/article/214899/unix_tip_rescuing_files_from_lost_found/
http://www.techradar.com/news/computing/apple/explained-lost-found-folder-in-os-x-712519
 )

I logged in, renamed his now ruined home directory.

I had him log in; in the absence of a valid home directory, OS X will create a 
new, empty one.

I then logged back in as the first user (fast user switching roxxors), and 
opened a finder window as root, per the directions above. This now allowed me 
to open his normally locked home directory in the finder.

Then I looked through the myriad of folders in /lost+found. Fortunately it 
looked like most of his /library folder was one of them, most of his Pictures 
folder another, etc. I moved the files and folders into the appropriate places.

Once I was done in finder I want back to the terminal window where I started a 
finder instance as root and control-c'ed out of the command. Then I went to 
users and did: sudo chown -R theuser:thegroup theuser/

Whenere theuser is the user's short name, and thegroup is the user's group. 
This can be determined by the follwong command in Terminal:
open a new Terminal Window and enter:
cd /Users
ls -l

You'll see something like this:

dbdev2:~ johnson$ cd /Users
dbdev2:Users johnson$ ls -l
total 0
drwxrwxrwt   18 root  wheel  612 Dec 14 16:31 Shared
drwxr-xr-x   21 helpdesk  helpdesk   714 Dec 15 10:42 helpdesk
drwxr-xr-x@ 260 johnson   johnson   8840 Apr 25 09:21 johnson
drwxr-xr-x   15 test  staff  510 Aug 20  2010 test

looking at the top line, root is the user, wheel is the group. Since 10.4 or so 
users have had their primary group one with the same name as their short 
username. (see helpdesk helpdesk, or johnson johnson). IN earlier versions of 
OSX your default group was 'staff'.

The chown command above makes sure that all the files in the user's directory 
are owned by him (CHange OWNership) since root was moving (and in some cases 
copying) the files many could have been owned by root)

After this, he was able to log in again and most of his stuff was as he left it.

I was still getting problems booting up as in taking 5-10 minutes to boot (In 
10.6, possibly 10.5, if the system boots up with a long progress bar like a 
safe boot, fsck is having problems with the drive. In earlier versions of the 
OS I think the spinning gear just keeps on spinning, making it appear that 
nothing is going on) It would eventually boot but take forever.

(Another useful hint: I rebooted holding down the Command-V keys; this boots in 
'verbose' mode, showing the old school Unix boot screen, where I was able to 
see that the system was repeatedly trying to repair the disk with fsck)

Connected it via FWTM to my iMac, tried Disk Utility to repair, no go. Tried 
Disk Warrior and DW once again proved it's worth, by handily rebuilding his 
disk directory and restoring his system back to normal.

His external drives for Time Machine (which I suggested he get a YEAR AGO!) are 
now winging their way here...

Caveat! 

As with ANYTHING done as root, you can really screw up the system. Using Finder 
like this is taking a heavy-duty power tool, removing all the safety guards, 
duct taping it to your hands and supergluing the trigger to the 'ON' position. 
If you don't know what you're doing, you can lop off a limb before you know 
what happened to you...

Use wisely :-)

Fascinating tale, which I appreciate your taking the time to share. It's 
because of the sharing that goes on in this group that I've learned so much 
about Macs over the years. The fact that you, Dan and a few others who are 
really, really hands-on as well as book-smart knowledgeable take the time to

I would say that some forms of multi-factor authentication can actually

personal information challenge. This has forced me to use the same 
phrase for all the questions because my favorite movie changes over 
time, I don't remember my first teacher's name, my mother's maiden name 
is public record, and so on.


IMO this is much more of a hindrance than strong random passwords.
