i want to change permissions for /proc/sys/net/ipv4/ip_forward and permission denied.when i want to delete it , operation not permitted.i know it is dynamically created file . but i want to chenge its permittion to read-only or delete it
Trying to change permissions on a file in /proc/sys/fs/inotify. The command syntax are:
Code: sudo chmod u+w max_user_watches and the result is:
Code: chmod: changing permissions of `max_user_watches': Operation not permitted Also tried to change it when logged in as root, same results. Parent directory permissions are dr-xr-xr-x, and are the same up the chain. Tried to change the directory permissions to u+w, that didn't work either. FWIW, /proc is part of the / partition, and it has ~600MB free space.
I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.

I've been using Ubuntu for about 2 years now, but still have trouble with some of the finer workings of linux. I have a laptop that I use for general computing, and a desktop hooked up to a TV as sort of a remote backup/htpc. A problem I run into is when I transfer files, they get transfered with the owner set as the original computer's account, and I can't do anything until I open a remote viewer and gksudo nautilus to change the permissions of the file. I looked at articles about permissions and uid's, gid's, and umask but can't figure out how to apply it to my situation.
I thought about doing something with groups but am not sure exactly what, and anyway, default group settings only give read access and what I'm really looking for is the ability to manipulate files and folders across the entire /home dir on my desktop from my laptop. Desktop is running 8.04 and laptop is running 9.10. BTW I am currently sharing through smbfs. I read that this has been replaced by cifs, but at the moment I would prefer not the mess with things if I don't need to.
I got two ubutnu servers running side by side, I need to transfer several dir's of files, incl sub dirs to the other server via ftp and retaining the file permissions and dir structure. Both servers have ftp access, I am assuming theres an ftp command I use on the destination server to connect to the source server and retrieve the files? All the files reside in the one dir and need to be copied to the same dir on the destination server.
While experimenting with rsync, I accidently deleted a bunch of files in the /proc directory. I think it was the directories: 1, 2, 3 ... 10.This happened a few days ago and after rebooting a number of times, I do not notice any problems.
the permissions for my home directory were accidentally changed from 'access files' to 'create and delete files', and I changed them back, but ever since then I am not able to change any preferences/settings at all. power management, themes, panels, emerald, anything. my user account is supposed to be the administrator, and all the user privliges are checked. how to get control of my computer back?
I need to record Tx/Rx bw in my c program at defined intervals. I am aware that there a bunch of available tools but I need a minimal version with only Tx/Rx bw with no other details. I have tried the tool bwm-ng which mostly serves my purpose but either it runs continuously in the console or saves result in html file. It does not have any options to save the result in txt file which could have been easy to parse.
Is there any other simple way to record Tx/Rx bw in a program?(without using tools from /proc/net/ or any) I am using Mandriva Linux 2.6.31.5.
I have a while(1) loop, and the error is: glibtop: open (/proc/stat): Too many open files This error occurs after about a half hour to an hour of running. I've tried running this multiple times, both with using glib_close() at the end of the loop, using glib_init() and glib_close() at beginning/end, and just using glib_init(). The strange thing is these have no effect on the actual glib_get functions.
Im reading in file /proc/cpuinfo into a char array.Im using strstr to search for a string im interested in (the cpu speed line) and storing it in another char array.I want to just store the line that contains CPU speed but im getting everything after the CPU speed line in the char array too.Is there anything better than strstr or is there someway i can parse the the payload data (i.e. the actual cpu speed)
I am trying to read the /proc/net/tcp6 file of a huge server (chat server) for monitoring the tcp6 connection states.
This tcp6 file has more than 26000 lines. For monitoring the server connections, my monitoring tool has to read the /proc/net/tcp6 file quickly in regular interval. Presently it takes minimum 6-7 seconds for reading the whole file.
My tool can able to read the normal file (26,000 lines) less than 1 second, but it is not possible to read the same size of proc file.
I have 2 questions:
1) Why proc file takes more read time than normal file?
2) Is there any way to read the /proc/net/tcp6 file more quickly?

I have to get soem statistic about interfaces from /proc/net/dev. but statistic on this file is reset when get reach more than 4G byte.I think linux has limitation on this case.
I have limited experience in terminal, but let me first explain what I am trying to do to see if there is some easier way to do it. Basically I want to change the skin in aMSN. I downloaded the new skin but am unable to unzip or move it without /root permissions. I don't know how to acquire this without being in terminal. So I figured there had to be some way to go into the terminal and use it to move the unzipped folder from the desktop to the aMSN skins folder.
I need to setup permissions for some files.The users on this Ubuntu system should be able to read/view the files.They cannot write/edit the files.Most importantly, they should NOT be able to copy the files anywhere. They should NOT be able to copy these files to another folder, USB device, etc.
I did a clean install of 10.04 over the weekend and copied all of my backed up files from my external drive back to my internal drive. However, I've noticed that when I moved all my files back, they're all now marked as being executable. I've since fixed this, but I was wondering why this happened to begin with?
I use rsync to backup my files (grsync to be exact), but when I do so I copy files from my internal drive, which is formatted as ext4, to my external drive, which is formatted as NTFS (I keep my external drive as NTFS in case I need to hook it up to a Windows machine). Does the file system discrepancy have to do with why my permissions change when I backup/restore my files? Is there a way to prevent this? Or should I be backing up my files a different way?
I made some files belong to root, so that my sister couldn't read them while she was staying with me, there were about 40 files altogether but I did them all at once by change the permissions of the folder and clicking "apply Permissions to enclosed files" but now I want to change them back to belonging to my user account so Opened a gksudo nautilus windows and I went on folder properties and set the permissions to [user] and clicked apply to enclosed files, but it only did the folder. I tried selecting all the files and changing them all at once that way but it won't let me, how can I make the files belong to me again, other then one by one? I dont know how to use the CLI that much.
I am using Ubuntu 10.10 Meerkat and everytime I attempt to edit the permissions of a file either using the command line or gui it does not stick. When I use the gui and click in the permissions tab and then choose execute file the check mark appears and then immediately disappears.
When I attempt to change permissions via the command line and execute a script even if the script was created by me it does not work and when I check the permissions there is no changes from the original before my attempt to add execute permissions.
Even when I change permissions for read and write they don't stick.
I had no problem when I was using 10.04 and need to get this fixed.
PS. I made sure I am changing permissions using root privileges.
I wanted to know whether its possible to prevent some user from playing mp3/any other media files, using the chmod command? Are the read and execute bits meant only for text/office files?
I'm trying to find out what is the difference between wifi0 and ath0 (atheros wifi card) in terms of packet counters shown in proc/net/dev pseudofile. The fact is that wifi0 and ath0 packet counters are different. I've read that wifi0 refers to the physical device and ath0 refers to virtual device over wifi0, so, as far as I know, packets counters in both devices should be the same, isn't it? Another annoying question for me is that ath0 doesn't show any erroneous packets, while wifi0 does.
I logged on today to find that all the folders in my home folder are empty when I look at them in nautilus. When I try to cd into them via the terminal, I get a message that says I don't have permission. When I cd as root, however, all my files are there.
Yesterday I was messing around with Apache authentication, and it appeared from Firefox that the contents of one of my directories was empty.
I checked, and I am an Administrator, etc. I'm on Ubuntu 10.04.
I've recently converted two Ubuntu 10.04 (one 64, one 32bit) machines to LibreOffice. We've used OpenOffice.org since early 2.x The issue is a database file created in OOo and now needing to be accessed in LO. As far as I know, there shouldn't be any issue with file compatibility. On the 64 bit machine, (a Ubuntu server installation - not headless) the file opens with no trouble and is fully accessible. (forms, reports, tables, etc.) However, on the 32 bit machine, trying to access the file over the network on the server via samba (because we also have Windows machines on the network, so I serve it all up via samba) I am able to open the database, but get the following error when trying to access any table, form or report: The connection to the data source "Mattress Prices" could not be established.
I have a shared partition on Ubuntu, 'dm-6', if I create a new folder in it, it has 'teocomi' as owner.If I create the folder from another (windows) PC the owner is 'nobody' and from Ubuntu I have to chmod/chown it in oredr to edit its content...Is there a way to set automatically permission and owner for newly created folders and directories?
I've been using Ubuntu for a few years and I am having issues trying to load .jar files and .exe files in Wine. I keep getting an error message that says my computer doesn't have permission to load these files. I've done some research and found people saying to enable the file as executable in the files properties, to enable executable in the permissions folder, and to allow source code on the Ubuntu Software screen, but whenever I try to check these boxes, they immediately revert to having a line through them instead. I remember when I was running Ubuntu a few years ago I was able to completely disable this restriction in terminal, but I can't remember what I did.
After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results. I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?
I want to add my daughter as a user and give her full permissions to all the same folders and files that I use. I have given her permission to folders and their sub folders however she doesn't have rwx on the individual files within the folders. What is the command line to set this up?
Also with the command;
Code: chown -R root:root files
what is the -R for and when do I need or not need it?
I'm sure that the issue I'm having is easily solvable once I gain some understanding about copying files - and file permissions in Ubuntu. Here's my situation:
I have an external HDD where I like to back up some files (I mess around with distros on my main machine and feel less stressed knowing the important stuff is backed up). I have an ext4 partition on the external drive where I have copied files, both through the terminal (cp 'filename' /dev/sdc3) and by drag and drop (gnome-terminal).
The problem is, once the files are copied, most are inaccessible. I can view them, but some directories and individual files say I do not have permission to open them. Others are accessible. This is from the same user profile that copied them.
How do I see what's going on? More importantly, how do I make files on external drives available to any user or OS (that can handle ext4)? I want to make sure that if my whole system gets effed that I could still do a reinstall of my OS and then access those backup files.
