Well I did something really stupid:sudo chmod 700 -R /Why? because it's late and I'm tired and somehow thought it was only on my current dir...Is this somehow fixable? I don't get my usual loginscreen so I guess through an tty?
View 9 RepliesI have a problem with my external hdd, I mounted it manually and in the mount table it says ive got rw permissions. But when i try to change permissions it says:
chmod: changing permissions of `whatever': read-only filesystem.
This is my mount table:
[root@localhost ExtHDD]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
none on /proc type proc (rw)
none on /sys type sysfs (rw)

I accidentally did a 'chmod +x foo' when i meant to do a 'chmod a+r foo'.

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.
I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

Code: chmod -R 666 *.rtf i've read help and the man page for chmod, and it seems that -R switch should make chmod work recursively, but it only alters files in the present working directory. could someone point out what i'm doing wrong?
I have installed php, mysql, and apatche. And i need the /var/www/ folder to be able to be read witten, and acsessed by anything. I have tried chmodding 777. But it still doesnt work.
View 5 Replies View Relatedit seems to me I can't get chmod to function recursively. I have a folder with a couple subdirectories in it and a few in each of those etc. Now, I want to give everyone read-write on all .c files. So, I typed in terminal:
Code: chmod -R 666 *.c However, none of the .c files in any of the subdirectories were touched, i.e. I could have accomplished exactly the same thing by typing
Code: chmod 666 *.c I did RTFM, and it seems that what I did initially should have been the ticket. What am I doing wrong?
I have been working closely to the Katana boot kit here recently, and this is bugging me. I am trying to use a new program to Katana called Forge. I have it on my flash drive, and I open the properties to make it executable, and when I click something it automatically changes back. I have tried the basic stuff, sudo nautilus.

I'm having problems with chmodding a NTFS directory. I'm having problems accessing the directory through samba because of some missing permissions, but when I try to set them, nothing happens.This is what I do:
Code:
root@proliant:/media# ls -l
total 32[code].....
I also tried to replace 'hdd.1' with '/media/hdd.1' and 'hdd.1/'
I have an external fat32 hard drive. It already has some files on it. Now, I mounted it and it shows the owner to be root. fine. but when I change the permissions, it does not seem to change it. I am not able able to access the directories, even as root !.I was able to create directories, but "luckybackup" wan not able to write to it due to permissions. I take it the lucky backup is executing as root/ but even otherwise, if I do chmod ugo+rwx, why do the permissions dont change ? (no erorr message by chmod).
here is the stuff: (ext drive mounted at /seagate)
rootubuntu--seagate# chmod ugo+rwx *

I'm such a newbie when it comes to Ubuntu, or any Linux varient, period. I was trying to install a driver for an HP All-in-One Printer and was trying all kinds of commands from different Google searches... still unsuccessful in the installation. I downloaded the file to my desktop, but after using a Chmod command someone mentioned, I now have a folder on my desktop named:
hplip-3.9.12
i right-click
select
properties
Basic Tab
Type:folder (inode/directory
Contents:unreadable
Location:/home/mesk/Desktop
Permissions Tab
Owner:root
Group:root
"You are not the owner so you cannot change these permissions". The folder's icon on my desktop has a red box with white circle on the middle right side and a lock symbol above that. I'm the only user so I don't get why the permissions are protected from me, how do i undo this?
What does chmod 000 do?when i create a chmod'd file with the 000 permission what happens?I tried creating a file with 000 permissions, and I was still able to read and write to it. So what what does chmod 000 actually do?
View 6 Replies View RelatedI recently installed Ubuntu 10.4 on an Intel machine. The machine also has Windows 7. So some of the partitions of the hard drive are Windows compatible (NTFS). They are all mounted when system is booted with Ubuntu and all files are accessible. However, when I try to change permission or limit access to a group, CHMOD command does not work. It doesn't return any error and everything seems to work fine but I can't change any permission.

View 6 Replies View RelatedI've had my share of troubles with Ubuntu before and always been able to find help just by reading the forums, but this time it doesn't seem to be happening. Basically, I think I did something stupid by trying to change the permissions on my home folder to 777. (I'm the only person who uses my computer and got sick of always having to get root permissions.) Halfway through the process, the computer slowed to a crawl and text in dialog boxes started getting replaced with empty squares.
Naturally I rebooted - or tried to. Regular boot didn't work, so I tried recovery mode, which was kind enough to tell me I had a kernel panic because sbin/init wasn't found. Here's where things got weird: I then tried to boot from my Ubuntu USB stick, and couldn't. I got to the USB menu, hit the "run" option, and after a few seconds of the Ubuntu boot screen, my monitor went blank. Actually, to be technical, it didn't just show a black screen - the screen shut off. That's as far as I've been able to get.
By the way, just before I tried what I'm now calling the chmod-of-death, I also had an update freeze in the middle. I am able to boot into Windows, and have checked my USB stick - all seems fine. Any thoughts on this? Worst case, I can reformat the partition and reinstall, but I'd rather not lose all that data.
UPDATE: Okay, so I *did* manage, after about ten more tries, to boot from the USB stick. I went in from there and changed all the permissions back to 755. Tried to boot in recovery again, and still getting the same sbin/init error - so I'm wondering now if it had more to do with the failed update than the permission change....
I'm trying to recreate a website on a local system using LAMPP. I need to change some file permissions on localhost.
I have tried running a normal Filezilla session, as well as running as root but the system always denies Filezilla permissions.
I know I can do it directly using CHMOD on it's own but I would like to try to replicate the FTP sessions I can run on my remote server where I can change permissions in Filezailla without issue.

In a rage of anger against VI I decided to open my firewall config file in gedit, made some changes and was then confronted by the fact that it was read only. I decided to change the permissions for the whole of the /etc folder with:
Code:
sudo chmod 777 /etc/*
This also changed /etc/sudoers so that now whenever I try to use sudo I get the error:
sudo: /etc/sudoers is 0777, should be 0440

I cannot change it back to 440 because I need sudo to do that.
Recently i was fixing a permissions error on my home folder. In the process i ran accidentally chmod 777 in the root directory. BIG mistake. Now i cant run sudo, or start network manager. I am currently on vacation and made a bootable version ov ubuntu on my flash drive, but i wouldn't boot. I think it is because i chmod'ed the grub folder (with is in the root) I have a boot CD a home, but is there anyway to fix it beforehand?

My question is, can you setup a ftp server and then connect to it from a windows pc on the same network with a client like core ftp? I want to do this to add files and make chmod a little easier if possible.
View 4 Replies View RelatedI have recently installed Ubuntu 10.10 (x64) and I have noticed that I cannot change the permissions of any of the files on my external drives.

They are all in "-rw-/drwx/-rwx------" mode. What should I do?
