General :: Where File Change Occurs
May 5, 2010
We can use inotify related tools (fam, etc.) to know "when" a file change occurs, but, Can I know where (file position, offset) this change was made? For example, suppose that you have a big file and you are monitoring changes on it, using inotify-tools package or something like that you can take acknowledged if another process chage that file, but How can I know "where" that change was maded in order to avoid read all file content looking for a change maded?

We are running into issues with a File Upload script written in PHP. We can upload files without issues except with .*x files (such as .docx) We are getting permission denied errors. The error occurs when we use move upload file, to the new directory within our PHP app. If we give the uploads folder 777 access, it works fine without error. I dont like that. So I set it to 775 (Also dont like this), but it didnt work until I gave group ownership to www-data (I really dont like this)
This issue only happens on our production server, which is Ubuntu 9.04, running Apache2.2 and PHP5 will all the newest updates. We also have all MIME's configured, and are able to download the file from Apache without error. The first thing we noticed before the file permissions error, was that the MIME type changed to .zip when we used mime content type function. But yet using the FILES array, it still showed .docx.

I have a bluetooth headset for a cellphone, which I would like to use with my Ubuntu computers. I'm currently trying to do this with a computer running Jaunty. I have successfully paired the headset with the computer. But when I try to send an audio file to the headset, I get the "Sending files via Bluetooth dialogue box, immediately followed by the error message:
Quote: org.openobex.Error.NotSupported and no file transfer occurs. I am able to do other Bluetooth operations with other devices - eg I can send/receive files between the computer and my cellphone. It just seems to me that using a Bluetooth cellphone headset is not supported, or that I am doing something wrong.
UPDATE: I just tried doing this with my other machine running 10.04, with similar results. It looks momentarily like it's going to transfer the file, then reports that "an unknown error occurred". Is it just not possible to use bluetooth headsets for cellphones with Ubuntu computers? That doesn't seem very likely: when the computer detects the headset, it reports it as being a "headset". So why won't it work? What am I doing wrong?

I have an ntfs partition that I wish to access as a normal user(non-root). For this I did the following. As root I created a folder /windows and did a chmod 777 -R on /windows. Then I added the following line to /etc/fstab
Code:
/dev/sda3 /windows ntfs-3g defaults,nosuid,nodev,umask=000 1 0
Now, the partition is mounted alright but the problem is that when any other user (non-root) creates a files in /windows (say by executing touch newfile) the newly created file has the owner and group set as root. The non-root user can create the file and he can also delete the file, however, he cannot change the permissions of the file and also the owner:group is always set as root:root. How do I get across this problem, i.e. how do I mount a partition, so that a non-root user can also change the permissions and ownerships of the files he creates.

I esablished a dual boot with Windows 7 and Ubuntu on separate partitions. Then, as I realised that Windows 7 was rubbish and Ubuntu annoyed me by losing wireless connectivity after an update, I decided to go back to Windows XP for a while. So I did what I probably shouldn't have done, and formatted the partition (or so I thought) with Ubuntu on, using Windows.
Now, on booting up the system, all I can get is the Grub Rescue prompt and nothing in the Bios menus seems to be of any assistance.
I've tried booting XP from a CD, but a blue screen error always occurs at the same point in the installation. I wonder if I should make a CD/external drive with Ubuntu on, reinstall it, and go from there?

I am running Linux Mint 8 on my Dell Precision 350 computer. Every so often (sometimes every few hours, sometimes every few days, it appears to be random) my desktop will crash and display the message:
"70822.286411 EXT4fs error (device sda1): ext4_ext_check_inode: bad header/extent in inode #139281: invalid magic - magic 800c, entries 121, max 3278020), depth 171(171)"
This is displayed several times on all of the terminals, but with different numbers each time. When this happens, typing any commands in the terminal result in the error message being displayed again. When I restart after this happens, linux generally displays "Give root password for maintenance (or type control-D to continue):" and I give the root password. Running "fsck /dev/sda1" seems to fix this problem for the next boot, but then it will come back in either a few hours or a few days. Reinstalling the distro does not work, as I have already tried this. I suspect a hard disk error, but before I run out and buy and install a new hard disk, I wanted to know if maybe there is some way to fix this through software.

nano /etc/hostname (after going SU)
And in that I type the new hostname.
Also I did this too...
nano /etc/hosts

I have a c file, and I want to open it but not in the terminal. After changing the permission, I tried: vi, pico, ed and vim. But, all open it in the terminal. How can I change the permission of that file to be opened and edited not in the terminal? When I change the permission from the terminal, it only let me edit it through the terminal, and when I check the permission of the file I see it as was it (no change). I need a permanent permission. Although, I command as a root.
