Change file access

Hello, how can I set access for /dev/console if I want to work with it as regular user.
I tried different arguments for chmod (a+rw in main), but after reloading it resets.
$ ls -l /dev/console
crw------- 1 root root 5, 1 Jan 14 20:44 /dev/console
What is the right way to change acces for that file?
$ groups

I did
sudo chmod -v a+rw /dev/console
and now permissions are
crw-rw-rw- 1 root root 5, 1 Jan 14 15:45 /dev/console
do your permissions change but you still can't write to it or do they not change at all?

Change file access in FTP

Hi, i'm new in java and i'm trying to make a program that moves a file to a FTP server, I already made that part of the program.
but i'm having problems finding the way of change the access of the file, when was already moved it.
This is an example of the code that i'm using to do the first part.
import java.io.*;
import java.net.*;
import java.util.*;
public class FTPConnection {
public boolean connect(String host)
throws UnknownHostException, IOException
return connect(host, 21);
public boolean login(String username, String password)
throws IOException
int response = executeCommand("user " + username);
if (!isPositiveIntermediateResponse(response)) return false;
response = executeCommand("pass " + password);
loggedIn = isPositiveCompleteResponse(response);
return loggedIn;
public boolean uploadFile(String serverPath, String localPath)
throws IOException
return writeDataFromFile("stor " + serverPath, localPath);
public boolean changeDirectory(String directory)
throws IOException
int response = executeCommand("cwd " + directory);
return isPositiveCompleteResponse(response);
I already have the code to take the file and move it to the server but i can't find the way to change the access.
I hope someone can help me with this thanks.

I already tried to use chmod but it doesn't work this is the example that i made
public boolean changePermissions(String Path)
throws IOException
int response = executeCommand("chmod 777 " + Path);
return isPositiveCompleteResponse(response);
but the file continue with the same permission. So i was wondering if i'm doing something wrong or is other way to do it.
Thanks for your help

Changing file access

hi ,
how to change read only access file to writable file ?????

Permission objects (e.g. FilePermission) are
immutable. I don't know of any way within the 5.0
JVM/core classes to change file permissions.So I guess the only way I can think of is by using Runtime.exec() and run the command for the specific platform you're on (e.g. chmod on unix/linux) to change the rights. Not a nice solution though.

Changing file access permissions?!

I have a MacBook Pro retina running os x mountain lion, if that helps any of you guys answer this question. I recently took a screenshot of an area of the screen using the command-shift-4 combination. When i was trying to open it, though, an error came up saying that i didnt have the permission to open the file. It told me to got to get info and change file permissions.
How do I change file permissions and why does it say this in the first place??
Thanks,
RZ

Doing a screen shot creates a file on the users desktop which they should already have permission to use.
So if it's saying you don't means there is something else wrong with your machine.
Do these to things first.
1: #6 Repair Users Permissions (this will fix the in user folder permissions)
2: #12 OnyX (free) cache cleaning and will repair OS X permissions.
..Step by Step to fix your Mac
What is basically going to happen is your going to reset the permissions of all files on the machine back to what they should be and not what something caused it to become off.
Doing all the OnyX steps in Maintainence and Cleaning is going to reset everything else in the system like caches etc., so it's like it just came from the factory which will cause those caches to rebuild anew and free of corruption that might have occured.
OnyX also has flags as it checks the drive for other issues, thus gives you a warning of other potential problems.
Make sure you have backups of your users files off the machine to a storage drive (not only TimeMachine) before you atempt any repairs as all the remaining software can be replaced except your files in case it turns out your problem is much larger than anticipated.

Change file access date

Anyone know how to change a file's access date? There is setLastModified() in the File class but I don't see anything for access date.

a\Access date is just the date you last opened it. To set it, you can open it, and it will set it to todays date.

After change the file access option 'No Access', I cannot start up my iMac. Only blue screen!

Hi experts,
I really need help.
I have several user accounts in my iMac G5.
Some reason - I don't know why I did - I went into the 'get info' of the Mac hard drive, and change the permission to the hard drive from 'Read and Write' 'to 'No Access' for the one of the user accounts.
After that, I switched the user as the one I just changed 'No Access'. But I couldn't do any action in that user space, like opening finder, starting any program.
So I re-started the computer and since then, I only see the blue screen (no arrow no nothing.).
I tried booting with Safe Mode, but still only show blue screen.
I tried booting with single user mode, still blue screen.
I can start up with the disk but couldn't restore the HD since there is no time point at all that I can go back.
What should I do? Please help me~

I tried booting with single user mode, still blue screen.
Changing permissions an a user account should not cause single user mode to fail. You changed permissions on something else. Could you provide more info on the folder you changed?
Some reason - I don't know why I did - I went into the 'get info' of the Mac hard drive, and change the permission to the hard drive from 'Read and Write' 'to 'No Access' for the one of the user accounts.
This is a little confusing. We need to know what folder you changed.
You might try Disk Utility repair permissions. Here is how to get into Disk Utility from the startup disk.
You can also get into the Terminal. Notice terminal is on the pull down. Check permissions on the root directory
mac $ ls -ld /

mac $
verify & repair your startup drive
To verify & repair you file system on the startup drive, you will need to run disk utility from you installation DVD.
This article will tell you how to get to disk utility. Once in a disk utility, you can go and attempt to recover the disk.

How to run disk utility from your startup DVD.
Insert your startup DVD into your reader. Power down your machine. Hold down to the c key. Power on your machine. This will bootup your startup DVD.
This will bring you to a panel asking you for your language. Pick your language.
You you come to the Install Mac OS panel. Do not install.
Click on Utilities menu item. This will give you a pulldown list of utilities.
Click on the disk utility.
You are now in disk utility. Pick your disk. Click on repair it should be on the lower right of the panel.
Once the repair completes successfully, you should update your permissions.
Verify a disk
As an alternative, you can verify that the filesystem on the disk is correct. You will not be able to repair the file system.
I suggest that you use disk utility to verify that your startup disk is OK.
Macintosh-HD -> Applications -> Utilities -> Disk Utility
Start up disk utility. On the left pane view, you will see a list of all your disks.
Click on your startup disk.
Click on the First Aid Tab.
Click on verify.
Hopefully your disk will verify. If not, you have to boot from your installation DVD and run Disk Utility from there to attempt to repair your file-system.

Image file access dates changing in mass (Windows).

In review of the access date properties for image files within a directory being accessed by Bridge within the Favorites area, they are all changing to the current time and date, even if the image is not viewed within Bridge. Why are the access dates of image files being changed even though they are not viewed? This makes it hard to determine whether an image can be archived or deleted based on last access if Bridge is always changing the access date every day. Thanks for any insight you can give on this!

Is there a way to turn off the caching of thumbs or metadata or whatever is causing the Access date to change when searching or reviewing images within a directory using Bridge?
As said, no experience with network environment. But Bridge is a browser and when you want to view things it needs to cache the file and data first.
Having said that, in normal usage (stand alone) it stores and saves this data in the cache folder and once it has done so it will not need to recache until you have made changes to the file. Check Bridge prefs / Cache/ Location to see where the data is stored when you are using this machine.
By default on a stand alone Mac (windows seems to have a similar cache file) it should be in the User Library/ caches/ Adobe/ Bridge CSxx and inhere is a plug in and a folder called Cache, containing several folders.
For Bridge CC there are 4 folders, 256 (the cache files of the thumbs) 1024 (containing HQ preview cache files) data (what it says) and full (containing the 100% previews in cache)
All files that have been fully cached (pointing to a folder the content window should show already good thumbs and the activity bar bottom left in Bridge window should not show any activity, only the number of items showing and items hidden) don't need to recache for that machine again unless you changed something to the file or added metadata.
So once cached there should be no reason for Bridge to 'access' the file again unless access means looking for the file to check if the saved data still applies to the corresponding file on your machine, but then al files should show about the same access time because this is a very fast process on a fast machine.
You can't deselect cache because as said Bridge is a browser showing the content of your files, and to show this it has to generate a thumb and if needed a preview. But as also said, once cached it normally should not start recaching until changes are applied.
You have several ways to set the quality of the cache:
There are two checker board icons top right that give you the option to set for cache. By default it is set to 'Always HQ' to have both good thumbs and a good preview when pointing to a file.
Then you also have to option to generate 100 % previews which provides you with almost instant 100 % previews for loupe in preview panel or full screen view and click. Logically this needs more time and generates a lot of big cache files, all depending on the files you start with and the size of your monitor.
Finally you have the option to use embedded previews only. This is a very quick method but provides low quality thumbs (black border around it) and when clicking on a thumb it first needs to generate a HQ preview that then will take time.
In Bridge prefs advanced there is the option to create also monitor sized previews which should provide you with good quality full screen when using space bar in Bridge to preview in full screen.
This setting also creates a bit larger cache files in the 1024 folder depending on the size of your monitor (logical).
And if you want to apply a search using the find command you also have to include non indexed files to search in all folders, including the not before cached files.
Like first time cache this first indexing takes some extra time but should only need to be done once and then be persistent until you add new files or folders that have not been cached or indexed before.
Until so far the theory for a stand alone. If you have the files stored in a Network and other stations have access and have different cache settings or monitor size settings there might be some other things going on, or someone else has changed the file on their station and then when you select that folder Bridge needs to recache the changes.
Hopefully this makes some sense for you?

Not Working: BlackBerry Link Remote File Access Remove Old BlackBerry from BB ID

I have: removed my blackberry q10 from blackberry link, wiped my q10, uninstalled and reinstalled blackberry link, have link version 1.1.1.32, blackberry q10 os version 10.1.0.2309 - which whenever I plug in the q10 after removing the device from link, says there is an os update, so I update it, and then it does nothing apart from rebooting the q10, or gives an error saying 'updates not available. Please check internet connection and retry.'.
Also, I have Logout/login on blackberry link, I know my q10 is activated as I have purchased items from app world, and on the computer the app world site shows that I have a q10 when I sign in. I am using the same BBID and have changed the password on my q10 to see if that made a difference, then signed out and back into link on computer with updated password. I have administrator rights on my computer.
I can access the q10 from my computer over the same wifi network, and it syncs files fine with wireless sync turned on. It is remote file access not giving the option to connect to my q10. 'BBID *email* isn't associated with a device running Blackberry 10 OS or an error occurred when trying to retrieve your information from the Blackberry ID servers.'
The problem is that although I have the same blackberry id for link and my q10, no devices show up on the remote file access screen, and I cannot access my files on my computer from my q10, yet I can sync them on my computer over the wifi network. How can I enable Remote File Access?
A problem could be that I have a Curve 9300 on my BB ID account, so if I could disable this (which I have no idea how to do after a lot of research), this might rectify why link cannot set up remote file access.
What I haven't done is wiped my q10 and uninstalled all user data from link at the same time, as then I would have to manually reload everything on my q10.
My q10 shows my computer in the settings\blackberry link\paired devices , but I 'cannot view files on *computer*'. Also, link does not show in the file manager. I set up my q10 as a permanent link not a one-off connection.

No one cares because it's not a z10 (I know because I am having the same problem and no one knows how to fix it and no threads for q10 fix)
Slàinte.
Not all things are good.
Not all things are evil.
But with an open mind...
You can see the difference.
Knowledge is power.

How do I stop DW CS6 randomly changing file permissions via FTP?

How do I stop Dreamweaver CS6 12.0.1.5842 randomly changing file permissions when it uploads files to my web server via FTP.
I can no longer trust Dreamweaver to upload websites correctly as it changes permissions on some files which then deny the server access to the file which in turn makes the webpage unreachable/return a 403 error.
This is driving me insane.
I'm using an early 2011 Macbook Pro 10.7.5.

Hi,
I'm having this problem too. Has Adobe fixed the issue yet? This appears to be an Adobe problem, not all the web hosts out there. CS6 is ramdomly (meaning: not every time) changing permissions on files uploaded with it and is not usable for web work until this problem is fixed by Adobe or a solution is provided. If I wanted to use a separate FTP program I would not have recommended that my employer buy multiple Adobe CS6 product licenses. One of the primary appeals of DW is the integration of FTP into the workflow.
I am using a destop iMac2.8 GHz Intel Core 2 Duo, 4 gigs of 800 MHz DDR2 SDRAM.
OSX 10.7.5
I am using DW Version 12 Build: 5808
Dreamweaver CS4 that I was using until this new purchase was working just fine. No file permisssion changes. I am being forced to go back to using it until Adobe posts a fix for this.
I should ask while I'm here: has anyone found a solution for this yet?
Thanks,

MaxDB KNLDIAG file access denied

Hi,
I'm a DBA recently assigned to support MaxDB database (ver 7.6) used by
SAP Content Server in our windows 2003/32 bit environments.
Initially, our windows support group granted the DBA group access to
the files on E:\sapdb\data\wrk\CD1 where the KNLDIAG and other files
are allocated. We were able to view the KNLDIAG file when errors
occurred.
However, when the database instance is placed offine and back online,
we loose access to the KNLDIAG file, but not the other files on the
same directory/subdirectory.
Can you explain what is happening?
Is MaxDB doing something behind the scenes?
What can be done so that we don't loose access to this file?
I would appreciate any help you can provide.
Regards,
Bill

Yes, no problem!
> Is MaxDB doing something behind the scenes?
Of course not - it's well documented
Unlike Oracle MaxDB does not use the same file all the time to write out the error messages.
Instead, with every restart the last file 'KLNDIAG' (and/or 'KNLMSG' in more recent versions) is renamed to 'KNLDIAG.OLD'. If there is already an 'KNLDIAG.OLD' this file is gone afterwards.
Then a new file is 'KNLDIAG' is created by the MaxDB Kernel with the default permission of the folder.
Usually these are dictated by the Windows account that runs the MaxDB-Service.
If you did not change this, this would be the "local systemaccount".
On my test system this results in default permissions that allow members of "Adminstrators", "Backup Operators", "System" and of course the "Owner/Creator" to access the file.
> What can be done so that we don't loose access to this file?
Simple: if you want to access it via OS tools, make sure that the user is a member of the "Administrators" or the "Backup Operators" group.
If you don't want to do that, just use the file access via the DBMGUI or DB Studio (or DBMCLI) to get access to the file.
regards,
Lars
p.s.
Maybe you didn't notice that by now - the KNLDIAG file is not simply written at the end of the file, but consists of a startup header part and a body which is cyclically overwritten.
For any newbies I cannot overstate the importance of reading the documentation [http://maxdb.sap.com] and/or get a training for it (SAP course ADM 515 really pays of here...)

Server 2008r2 and windows 7 pro slow to no networkshare file searching and file access (green progress bar)

we are running a windows server 2008r2 sp1 domain controller and a 3com gigabit switch to which 7 windows 7 pro computers are connected. We are only using the windows server to distribute a few printers and as a network share (z drive).
we are storing all files (word documents only) centrally on the server (z share), and files are accessed and written to the z share.
Problem is that file access from the z share on the windows 7 client computers is at best buggy. we are able to browse the z-share, but as soon as we want to search the z-share for files (f.i. use file explorer with "content: memorandum") the green
progress bar shows and no search is performed. something like alphabetically sorting a directory on map/file name on the z-share also shows a green bar with no sorting. manually going to the files works.
One thing i noticed, sometimes not all files that one user created and stored on the server is visible and can be found by another user. I prefer to disable all offline file caching setting, because that feature is not used. no files should be made accessible
offline. i don't know where to change that on the server side.
I am reluctant to experiment on the server end (2008r2 sp1), so i tried a few suggested solutions on the client end (windows 7 client)
I tried disabling offline file caching
i tried properties (z share) ==> advanced and map optimizing and several options there
i tried disabling the smbv2 protocol and disabling the smbv1 protocol (using
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsi command etc. posted by microsoft)
i tried disabling windows defender
i tried accessing the z share via ip and server name (the share is mapped via its servername, e.g. dennis-dc1\share). still the same
file searching on the clients c drive ('own harddrive') works much better, file searching on the server also works.
any suggestions or solutions that i can test on the client side, as mentioned i am reluctant to change something on the server side. if a solutions works, i prefer to change it on the server side.

Hi,
The issue could be due to windows indexing service taking long time in sorting and searching in mapped drives. Please try the steps belwo to disable windows indexing service or search service on the windows 7 client to resolve the issue.
You can click on Start and select Control Panel, click on
Programs and Features, go into the Turn Windows Features on or off section Scroll down the list and uncheck the box next to Indexing Service or Windows Search.

Mandy

The name of the file that you are trying to access is MM_XSLTransform.class.php. It is a PHP class created by Dreamweaver for the XSL Transformation server behavior.
The servers php is 5.2.11, as it has been for sometime, so I know that it previously worked with allow_url_fopen = on and allow_url_include = off
Judging from the error message, you are trying to include the file using a URL, rather than a file path:
Fatal error: require_once() [

Change the URL to a file path:
require_once('/homepages/0/xxxx/htdocs/includes/MM_XSLTransform/MM_XSLTransform.class.php');
Is it possible for phpinfo() to show allow_url_fopen = on yet be actually off on the server?
No.

Permz - Quickly change file permissions in any file manager

Designed to be integrated into any file manager, permz is a bash script which presents a GUI menu. You can use it to quickly change file permissions and ownership as a normal user or as root, and delete files as root. I wrote this because I have yet to see a file manager that isn't cumbersome for this - the mechanism is usually buried on a second tab of the Properties window, and changing permissions often involves multiple clicks in a grid. To change the owner of a file, you need to type the username. And if the file is owned by root, you can't do anything.
permz --help
Presents a GUI menu for changing file permissions/ownership. May be run
as a normal user or root.
Requires: zenity gksu
Optional: sudo (recommended to prevent multiple root password prompts)
Usage: permz FILE [...]
MENU FUNCTIONS:
rwxrwxrwx Sets file(s) to given permissions
Sticky Clear/Set Performs "chmod -t" or +t to clear or set the sticky
bit. You may select to clear/set sticky in addition
to changing other permissions.
Recursive go-rxw "chmod -R go-rxw" on file(s) recursively, denying
access to non-owners
Recursive go-w "chmod -R go-w" on file(s) recursively, denying write
to non-owners
Recursive ugo+rX "chmod -R ugo+rX" giving read access to all. Also
sets +x for directories and executables.
Recursive ugo+w "chmod -R ugo+w" on file(s), giving write to all
(You may select several compatible recursive functions above at once)
Owner USER As ROOT Sets ownership to USER:USER as root
DELETE As ROOT Deletes file(s) as root. Must be used alone or with
"Perform Recursively" (to delete directories - USE
WITH CAUTION). Not available if permz is run as root.
Perform As ROOT Run as root to change selected permissions.
(Use of root is automatic when changing ownership)
Perform Recursively Adds -R to all chmod, chown, and delete commands to
descend into subdirectories. Use in conjunction with
any other functions. (Recursion is automatic for
"Recursive" functions above)
Current su command is set to: gksu -gS
If you're somewhat familiar with bash, adding additional options or changing the existing ones is straightforward.
I have tested it pretty thoroughly but if you do encounter anything amiss please let me know.
More details at http://igurublog.wordpress.com/downloads/script-permz/
And in the AUR at http://aur.archlinux.org/packages.php?ID=36978
Instructions for integrating permz into PCManFM-Mod are here.

Done - thanks for the tip. I also left the old code active in there with just the menu option disabled, so if anyone wants it the other way or wants both it's easy to enable. The difference is that the old way won't make any files +x, just dirs.
permz doesn't provide every possible setting of permissions, just common ones, so you may want to customize it. But I used to have these as user actions when I used Krusader and I found these were the handy ones, at least for me.
