Sudoers file is empty - along with several others
Note: This is a repost because I got no reply when I posted last week.
So, what would you think of a /etc/ that had a lot of empty files - passwd, sudoers, etc.
In several posts a well respected contributor stated: "If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator."
I would normally think is right but .... After doing an fresh install of Mt. Lion to 10.8.2 with a migration of user data and other setting from a seperate disk, I am getting the "<username> is not in the sudoers file..." error message for admin users in the terminal - for all sudo commands ....
Confused I went and created a new admin user and tried again ....same ....
I went ahead and software updated to 10.8.4 with all other updates and then back to the terminal. Same thing .....
I then typed this at the terminal
cat /etc/sudoers
and nothing happened ....odd.... so then
la -lsaG /etc/sudoers
and the sudoers file size is 0 ( zero ) .... odd ....
so then
la -lsaG /etc/
and I notice lots of critical security related files are empty - 0 bytes - nothing in them....
Thinking " *** and have I been hacked" and "How can a fresh install of Mt Lion, well protected from the interwebs be hacked allready."
So, the question: What would a senior sysadmin type or an apple expert think of a /etc/ that had a lot of empty files - passwd, sudoers, etc.
Thanx for taking a look....
Here's the /etc situation.....
-bash-3.2$ ls -lsaG /Volumes/MtLion_10.8.2/etc/

HELP I have lost all my motion 4 content from all the files, ive looked in all the files and they are all empty. can i get replacement content as I my dvds where stolen along. with my other laptop. any Ideas. would be a great help. For Motion 4.
Try a hard reset:- hold the home button AND the power switch - ignore the red "Slide to power off" and wait ubntil the iPhone powers down, and then restarts - at the Apple logo, release all the buttons and see if your contacts reappear.

the flood filter is in my plugins folder along with the other plugins I have, but not in cc 2014. It's also in Adobe bridge associated with cc 2014, but not in cc 2014 Photoshop. i hope you get this because i forwarded your info to HCS and now I'm all mixed up as to this gets forward.
Unfortunately, you are not addressing Adobe here in the user forums.
However, there are many highly experienced volunteer users here willing to help.
Can you please clarify: are you saying that your Flood filter (whatever that is) is in your Bridge folder but not in Photoshop?
UPDATE: I Googled your Flood Filter and discovered it's not an Adobe filter at all. Have you contacted its manufacturer, Flaming Pear? What do they say? -
Query of GL line items along with "the other side of the JEs"
Hello All,
I am trying to create an ABAP program or SAP query that would allow me to create an output of all line items posted to a general ledger account for a particular fiscal year(s) along with the other side the journal entry.
Said another way, I want all documents posted to a general ledger account along with the rest of the line items included with those journal entry.
For example, if I wanted to do this for Bad Debt Expense (P&L acct), I would like to see all those bad debt write off postings that were (credit Trade AR and Debit Bad debt Expense) vs. adjusting the bad debt reserve or any other posting in there.
Rather than looking at each transaction individually, I think this query would allow me to see the big picture of all posting to a particular account.
Any help is appreciated.Rob,
I appreciate the insight. I think you answered my questions, but could you provide me with a little more detail so I am on the same page as you.
For the BSIS and BSAS, I am assuming I can just use a FI t-code FBL3N to obtain the information.
Could you explain to me how to get the output in such a way and how to include it in the BSEG to get the complete journal entries for all of the document numbers I would get from the FBL3N. Or can I perform this in one function.
Thank you. -
Yesterday I did an update on software to get the facetime to work. It downloaded along with eight other updates an Itunes update now I cannot even get Itunes to open I am now completely frustrated Now two applications are not working. Help
Hi,
I tried opening it from the application folder and nothing happens. I have tried from the dock and the same thing. Unfortunately this is not the application that I ws intending to work on. This was running perfectly fine for me. I have a lot of music on it. I know all is still there because I can see it through spotify. I started looking for help with Face time with came up with a needing proper credentials in order to open. Now neither open after a 9 an automatic download of nine updates. At this point I don't know what else to do. -

In CS6, how do I access the Adobe Camera Raw plug in that's listed with my other (easily accessible) plug ins: I can't find it through "automate", or "Filter" or "extensions".. I am on iMAC 10.9.5 (Mavericks)
I believe camera raw as a filter is CC only. You can access camera raw by selecting a raw, tiff or jpg image from your drive. Raw is the only one that will open by default. You must tell camera raw to open tiff and jpg in the preferences.
You can also use file>open or file>place then specify camera raw as file type. In this case it will open any of the three formats without changing the preferences.
Once the image is in Photoshop, it should be a smart object if you choose open as object instead of open as image in camera raw. As a smart object, you can double click on the thumbnail in the layers panel. This will open camera raw with that image. -

When I wish to update an app or purchase an app on my iPhone, i get the message that Verification is required. next I am presented with entering the 4 digit security code for a credit card whose complete number is greyed out except last four digits. I can see itnis the old expired creit card. My Famiiy Organizer/husband has since updated that credit card, but I have no ability to sync up to the new credit card number. Shouldn't my family organizer payment updates immediately trickle down to the members of the family? I am locked out of purchases (even mere app updating), because I have no control over changing my own payment methods. I'm not asking to have my own separate card on file (as many support discussions reveal); I am simply trying to sync up to my family organizers payment method. It didn't automaitcally update member devices. I tried to update my own payment in SETTINGS, but its all greyed out since I am not the family Organizer. Talk about going in circles! I have 50 apps that I cannot update. Help!
You can create an App store account without a credit card, however that won't help you with updating your previous purchases. Apps are DRM protected, and tied to the account that was used to originally purchase them. There is no way to overcome this DRM protection or transfer them to another account(Itunes support can if you contact them). If you want to create an App store account without a credit card, follow the directions here, but bear in mind the DRM protection mentioned. If you use this account to download free apps, you will have to use this same account for all future updates:

I keep losing my Firefox Toolbar along with my other Tool Bars.
I keep losing my Firefox Toolbar so I can not get to my Bookmarks, Tools etc. Today I have no Tool Bars at all.
''If you do not have a tab bar, just page content from corner to corner:''
Could you check that Firefox didn't switch to its full screen view? You can switch that using either:
* F11 key on the keyboard
* slide the mouse all the way to the top of the window and watch for the tabs and toolbars to slide down, right-click a blank area of the tab bar > Exit Full Screen Mode
''If it's a regular window with a tab bar but no toolbars:''
This could be caused by an incompatibility with one of your extensions, or a corrupted data file.
If you tap the Alt key or press F10, can you call up the classic menu bar (File, Edit, View...)? If so, try Firefox's Safe Mode. That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
From the Help menu, choose Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins will still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Do you have your toolbars in Safe Mode? -
File Server Cluster along with SQL Cluster
Hello There,
I have got SQL 2008 R2 cluster running on Windows 2008 R2 Ent OS.
Can i use the same cluster to host file server cluster? If yes is it advisable to do so.
Regards,
Maqsood
Maqsood Mohammed Senior Systems Engineer MCITP-Enterprise Admin & ITILv3 Foundation CertifiedI have got SQL 2008 R2 cluster running on Windows 2008 R2 Ent OS.
Can i use the same cluster to host file server cluster? If yes is it advisable to do so.
1) Upgrade to Windows Server 2012 R2
2) Virtualize all of your workload (SQL Server, File Server etc)
After you'll be done it would be much easier to handle isolation inside your VMs and with a decent level of hardware resources allocated you'll have no issues running SQL Server and File Server @ the same time. If you don't virtualize I agree with Tim -
doable but not desirable :)

as I stated. the white in any file I open in PS s a warm white. I don't know how this happened or how to fix it. I do know it is not my PC or moniter. Only in PS. any hepl is appriciated, thanks, P
My5cats, Cris may have more to add but here are some thoughts. A calibrated monitor does have warm whites. We perceive a blue white as being correct but it isn't. i don't know if you are using monitor calibration or not. One possible area is that Photoshop is set to a paper or some other gamut. You can check (in PS) by going to the Edit menu > Color settings. Here is a picture of mine. I set the working space to sRGB which is used for the web and many printers. If you get a correct setting , consider saving it.

Can anyone help?
Here you go > Resetting the PRAM
If a PRAM reset doesn't help, try accessing OS X Recovery.
Shut down the Mac and wait about ten second\s.
Then startup your Mac while holding down the Command + R keys. Let go of those keys when you see the spinning progresss indicator.
With any luck, you'll be able to access the built in utilities to verify and if necessary, repair the startup disk.

How to write newline character to file using bytes along with content
Hi All,
I need to write headers into the file using byte[]. I am creating the strings of header which will form the different rows in the file. I am new to java and would like to know how to embed new line character so that when the byte[] is written to file headers come in different rows.
like
hrd1:abcd
hdr2:1234
when i embed \n and \r in string and do getBytes() and write it to file, some boxes are written in the file and everything comes into single line.
Please advice me the correct way .
Thanks in advance.
Cheers!!
Puneetnot sure about it, but i was always told that "\r\n" meant "new line" on "lots of documents" whereas "\n" only or "\r" only were meaningless on some type of documents
