 When: Fourth Wednesday of each month at 7:00PM
 Where: DeVry University / Keller Graduate School of Management - MAP: 6751
 N Sunset Blvd, Glendale, AZ

 Directions: Exit the 101 @ Glendale Ave - go East to the first traffic
 signal light - turn right at the light. Go to the flashing red light signal,
 stop first, then turn left (East) to Sunset Blvd (pass thru several stop
 signs - Sunset is the last street prior to the actual buildings). Turn right
 on Sunset and drive past the open air entry on your left . Turn right into
 the parking area and park. Enter through the open air entrance, but go into
 the first set of doors on your Right (no, not the DeVry doors on your left .
 Once thru the doors, turn left and walk back to the elevators - take one of
 them to the third floor. Look around - see the doors with the DeVry / Keller
 decals? Enter, turn right down the hall, then left to room 315 on your left.

Re: rsync help the gramma

2010-12-09 Thread Dazed_75
One thing I might point out though is that you (Betty) said you did the
backup about once a month and your example shows rsyncing to a directory
named for the month (October).  That's fine but some people use rsync to
update a single backup destination so they don't keep each backup
separately.  You choice which best suits you, but I thought it worth
mentioning.

 allows for staging different backup sets over time and yes, each

 two computers over a network too.

Re: rsync help the gramma

2010-12-09 Thread Bryan O'Neal
This is true - if you change the destination folder you do copy
everything because rsync does not know you copied anything before.
Rsync syncs. Thus if you wish to sync /my/files/ and
/media/my/backupfiles/ it copies everything from files to back up
files on the first run then every subsequent run it copies changes.
But if I ask it to now sync my/files/ and /media/my/NEW/backupfiles/
it must first copy every thing again because non of the files in
/my/files exist in /media/my/NEW/backupfiles/

If you want to have say /my/files backed up every day with that days
changes but you also want to keep track up each change separately (aka
have a snap shot for every month) so you can go back to prior
versions, then you want to look at rsyncs cousin rsnapshot.

Used in combination with rsync rsnapshot keeps track of changes by
copying files that have changed and creating links to previously
copied files that have not changed.

Here is a quick blog post and a set of narrated presentation slides I
did on rsync and rsnapshot a while back
http://mlwtech.blogspot.com/2009/04/rsync-and-ssh-keys-presentation-on.html

The audio auto-play and self progressing slide features are all messed
up because I did the auto-play stuff on a windows box but if your
interested you can play each slides associated mp3 manually. I keep
thinking I am going to go fix this by simply web linking the
associated auto play mp3 files or manually dealing with relative paths
but I am a bit busy... But I digress! The post and associated slides
are good and you may find the info very useful :)

 I absolutely agree.  My company laid me off on the last day of

 Allot longer than the exact degree you have.

How to repair the file system within in a ISO file

2010-12-09 Thread Shawn Badger
So I ran into this problem the yesterday and Google has yet to reveal
the secret of how to fix it.

I have a disc that someone else burned that is has some errors on it.
The source is gone so I cannot just simply reburn the disc :(

I was able to use ddrescue to get an ISO image of the disc created,
but when I went to burn that it just replicated the error to the new
disc.

Does any one know how to do an fsck  (or similar) on an ISO image?

I tried just doing a fsck -y disk.iso , but it just comes back like I
used a bad option and I can repair it while it is mounted.

Bryan wrote:

This is true in the general case.  However, you can tell rsync about
the files you copied before with the --compare-dest, --copy-dest,
or --link-dest options.

 Rsync syncs. Thus if you wish to sync /my/files/ and
 /media/my/backupfiles/ it copies everything from files to back up
 files on the first run then every subsequent run it copies changes.
 But if I ask it to now sync my/files/ and /media/my/NEW/backupfiles/
 it must first copy every thing again because non of the files in
 /my/files exist in /media/my/NEW/backupfiles/

If you use
rsync -a --link-dest=/media/my/backupfiles /my/files/ 
/media/my/NEW/backupfiles/
any files that are unchanged since the previous backup to /media/my/backupfiles
will not be copied by rsync.  Instead, they will be hardlinked from
/media/my/backupfiles to /media/my/NEW/backupfiles.  IMHO, rsync is
simply amazing.

Many scripts use this feature of rsync to give you incremental backups
that look like full backups.  Bryan mentioned rsnapshot, which I haven't
used, but looks interesting.  I use dirvish.  I set it up to do an
automated nightly backup of the several systems I have at home.

Here is a list of my toplevel backup directories for one system:

base $ ls
./ 20100103/  20100801/  20101017/  20101125/  20101202/
../20100207/  20100905/  20101024/  20101126/  20101203/
20081005/  20100307/  20100912/  20101031/  20101127/  20101204/
20090104/  20100404/  20100919/  20101107/  20101128/  20101205/
20090405/  20100502/  20100926/  20101114/  20101129/  20101206/
20090705/  20100606/  20101003/  20101121/  20101130/  20101207/
20091004/  20100704/  20101010/  20101124/  20101201/  20101208/

Dirvish has left me nightly backups of the last 15 days and weekly
backups of the last 3 months, monthly backups for the last year,
and annual backups prior to that.  (Dirvish backed up nightly for
the last two years, but has culled older backups according to the
schedule I gave it.)

Each of the directories contains a full snapshot of the files at
the time they were backed up.  Note that there is no redundancy.
There is only one copy of each file that hasn't been changed, with
links to it appearing in multiple directories.

From: Shawn Badger sh...@badger.pro
 I have a disc that someone else burned that has some errors on it.
 I was able to use ddrescue to get an ISO image of the disc created,

What filesystem was on the CD?  This is important.  It may be ISO9660, UDF, or
something else.  What, specifically, are the errors that you're seeing?  Did

I don't know of any fsck for ISO9660, since that's really not meant to be
written to.  The structure of ISO9660 is actually not that complicated IIRC. 
UDF is more complex and can be written to.  I don't see an fsck.udf here on my

be called udffsck on your distro.

Re: rsync help the gramma

2010-12-09 Thread Jason Holtzapple
You might also check out the Déjà Dup tool. It also does incremental
backups correctly (it is a front-end to duplicity).

As long as you don't need some of the more advanced features of
duplicity, rsnapshot, rdiff-backup, etc, it works quite well on the desktop.

Re: How to repair the file system within in a ISO file

2010-12-09 Thread JD Austin
Can you mount the image in loop back mode and get the files out?
assuming it is iso9660:

mkdir /tmp/iso
mount -o loop -t iso9660 /tmp/cdimage.iso /mnt/iso


Another alternative is to use unstoppable copier assuming you can read the
directory structure/etc from http://www.roadkil.net/unstopcp.html

Re: rsync help the gramma

2010-12-09 Thread gm5729
I use -avczPW for switches. very rarely do I automate a delete and it
is always AFTER a full copy. If you put a / in the wrong place you can
nuke your whole set of backups. So beware... other than that rsync IS
the way to backup. It is so featureful and once you set up your style
makes it pretty brainless to use. Rsync get sym links, hard links, and
permissions, mod dates, the whole schbang. The wonderful thing too
about rsync is if it gets interrupted it doesn't corrupt your whole
backup. So when you restart it it adjusts itself for source and
destination and then just restarts the backup from the last completed
file.

If this is just a data disc it most likely is in 9660 format.

ISOMaster would probably be able to mount the image and you could just
yank the data off that you want. Then make a fresh start of what need.
Unless that data is absolutely applicaton specific or encrypted with a
certain rev #, who cares about the apps on the disc, the data is the
most important.

gramma thx note

2010-12-09 Thread betty

thx, steve,alan, joseph and anyone i forgot !
good pick up  ; i AM doing backups with names of the month, so it IS 
backing up everything each time since it is a different name. i 
understand that but was doing it because i was so paranoid that it would 
miss something ...  so i have two months backups on the ext hdd  - oct 
and august. usually when i do the next backup, i put in the new month 
and delete the  oldest one. but once again, it is backing up everything 
of course.


so, should i try to rename the october file then just always use that 
for backups. ? or should i just call everything october from now on, 
hehehe. fine with me, easy to remember.


yes, to the question, it is all ext3. randy larson taught us that in the 
one linux class i took in 2000 (?) to get started. he was so helpful 
that was one of the reason i totally got into using linux.  very nice, 
like the people on the plug list.


one thing he said, i think, was to do a 'cron' job for stuff to happen 
every so often. (?) is this something that would lend itself to that say 
every week or every month?
he taught us that unlike the evil m$ you don't have the computer asking 
you 'are you sure you want to do this' when you are in the command line, 
that is why i am always so careful (and fearful ). it's also why i don't 
do backups as often as i should because it takes me about 1/2 hr to v e 
r y  c a r e f u l l y check everything i write before i hit enter.


have a nice Christmas party, u cheese cake !

There is a program out there that does something similar to this.  Its 
called BackupPC, and here is its work-flow in a nutshell:


Create a directory for each machine to be backed up
Create a directory for each backup to be performed (one per day/week/etc)
Copy all links (hard links) from previous backup
Read a file from the target over ssh/rsync
Is this file already in the backup?
  Yes - Has It Changed?
Yes - Add file to pool, overwrite old hard link to point to new file
No - Leave link alone
  No - Leave link alone
Read next file and continue

This causes the system to do a incremental backup every day, but it acts 
like a full backup.  Files are removed from the pool once it is A) 
deleted  B) no longer referenced from an old backup.  How long it keeps 
backups and when it creates a new file regardless (i.e. full backup) is 
configurable.  This program is especially useful for backing up multiple 
machines (as it is smart enough to recognize same files from multiple 
machines), and I know this is not your case... But I thought maybe the 
workflow could be useful for you to look at in designing your own backup 
policy.

Betty,

I might be able to help.  I haven't used Pitivi, but I would be very
interested in learning more about it.  As far as sending videos to Europe,
you will have to use PAL instead of NTSC because their systems do not
recognize NTSC format.  If you are going to post to your website, then you
may want to look at F4V as it is smaller and uses the flash player which
just about everyone has on their system

Hope this helps you,

change the password.

Re: Don't remember password.

2010-12-09 Thread keith smith

And once in you can issue passwd username 

you will then be prompted for the password and you will need to enter it 
twice.  

I've never changed a user password while in single user mode so I hope this 
works.  My system is setup where I have to be sudo or root to change a 
password.  Unless of course it is my password I'm trying to change.

You can find your users by listing then with the cat command.  They are in the 
/etc/passwd file.

So do this : cat /etc/passwd

2010-12-09 Thread Michael Havens
I think the link you sent will help it teaches how to eraase all
passwords (I think) I'll give the guy who installed the OS a day to see if
he remembers the password he he3 set. I hope he does because I don't have a
knoppix disk. I do havee a PHLAK disk and I think that will work as well. If
not maybe that PLUGer on Mingus mountain can help me out.

Re: Don't remember password.

thanks for the help guys I finally got the password reaset.  It seems
that root and UID passwd needs to be the same. I know that isn't the way it
normally works but it didn't work right for me until I did that.
