Permissions

I have been getting permission denied issues when trying to log into as root. I have set my password and when I type su - root and enter in my password I keep getting either password incorrect when I know I am typing it in correctly or acess permission denied from su. Can anyone explain what I am doing wrong. I am trying to get into /etc/passwd for homework assignment and I get permission denied when logged in as my user. Any help will be great. I have in the past been able to logg in to root but now I cant seem to get into it. This is a new install of ubuntu 14

Hi everyone,

I created a fuse mountpoint. After mounting, the file permissions are all screwed up and it says I cannot ls or cd. Permission denied.

The file permissions look like this:
d????????? ? ? ? ? ? temp

and when i list the mounted devices I get:
/dev/fuse on /temp type fuse (rw,nosuid,nodev)

I used mono-fuse. I just created a new folder with permissions 777 and then did a mount. After unmounting I can do all operations, but when I mount, I get such error.

I used
HelloFS.exe that comes along with mono fuse for testing. Can someone shed some light on this weird behavior and what mistake ive done. Thank you !!

hi experts

I am rsyncing a user's home dir across the NFS and the local PC, but when it tries to copy over the hidden files it fails with permission denied. Both dir are owned by the proper user and I am root when I execute the script, so I am not sure what went wrong here.
For example: this is the content and permissions of the source:

-rw------- 1 user test 115 Nov 14 11:28 .bash_history

and here is my error:

rsync: send_files failed to open "/home/user/.bash_history": Permission denied (13)

Thanks

Im trying to copy a directory..

Error message:

Hi,
I made some little applications with qt creator and i wanted to run them on an embedded linux board (linux 2.6.24). To transfer the files i use a SD card. If i move the applications to "/bin" after having mounted the SD card and then "chmod a+x" them then i have no problem running them.
But if i mount the SD card and try to run the applications directly in the folder where i mount it i have an error : "Permission denied". Also when using the command "ls" i notice that if i keep the files in the mounting folder and try to "chmod a+x" them, the modification don't happen. They stay "greyed" and don't go "green". (I don't know if this color code is a standart for linux terminal but maybe this could help you understand the problem).
When mounting the SD card i use the command :
Code:

mount -t vfat /dev/mmcblk0p1 /mnt/SD

So the files are located in /mnt/SD.

Am i missing something or is it not possible to run something like that ?

EDIT :
I tried "mount -t vfat -o umask=0000 /dev/mmcblk0p1 /mnt/SD" to chnage how i am mounting the SD card.

Still "Permission Denied".

With "ls -l" i can see that the permissions are staying :
-rw-rw-rw-

Even if i try something like "chmod 777".

It seems to be a problem related to the fact that the sd card is formated as fat32 but it must stay like that.

am trying to use tar in combination with find, the goal is to all files in /export that have been modified in the last 24 hours (back up purposes), then tar them so I can untar on the backup server, updating just the modified files.

Perhaps there is a better way, however, I have tried using cpio but the problem come in when I copy to the NAS drive (NTFS) I lose all my owner/group and permissions. I have found that if I tar the files, then copy them to the NAS, when I untar on the server, it will retain the owner/group and permissions.

So… here is what I have tried:

First, I use the find command to see what files should be in the tar archive.
Code:

/export $ find . -depth -mtime 0 -print
./file4
./file3
.

Ok, that looks right, now I will try to pipe that in to tar
Code:

/export $ find . -depth -mtime 0 -print0 | tar -czvf backup.tar.gz --null -T - 
./file4
./file3
./
./share/

./share/file3
tar: ./share/.directory: Cannot open: Permission denied
./dir1/
./dir1/file1
./file4
./file2
./file3
tar: ./.directory: Cannot open: Permission denied
./list
tar: Exiting with failure status due to previous errors

It seems that it is trying to tar all the files in that directory. When I view the files in backup.tar.gz all of the files from /export are in there not just the modified ones

Hi, I'm having trouble configuring my vsftpd version 2.2.2 on Centos 6.6. I successfully log in, but I cannot make any changes (creating files, directories, whatever):
ftp> mkdir t
550 Permission denied.
ftp>

This is how my vsftp.conf looks:
Code:

anonymous_enable=NO
local_enable=YES
local_umask=022
dirmessage_enable=YES
listen=YES
pam_service_name=virtual-ftp
userlist_enable=YES
userlist_file=/etc/vsftpd.user_list
userlist_deny=NO
tcp_wrappers=YES
write_enable=YES
guest_enable=YES
guest_username=ftp
local_root=/mnt/storage/ftp

All users are mapped to the ftp user. /mnt/storage/ftp is owned by ftp and there are no permission problems (the mount point is /mnt/storage). I use pam for authentication, which seems to be working fine from what I can tell from the logs and the fact that I can log in, of course.

/mnt/storage is a linux partition and it's mounted like this:
/dev/sdb5 /mnt/storage ext4 defaults 0 0

Which is really unimportant, because I tried to use the root partition also, and I get the same problem.

On some site someone suggested allow_writeable_chroot=YES, but this directive is not identified by vsftpd.

I kind of ran out of ideas. Any suggestions?

Linux Newbie here...running Ubuntu 14.04 LTS

Downloaded a couple of binaries/executables to the Downloads directory. ./command runs just fine but copying the binaries to /bin or /usr/bin says permission denied. I used chmol

After digging a bit more, realized that my FS is being mounted as read only!. Not sure why. /etc/fstab says UUID=8559f1a0-60e0-47e4-922d-9175f282fa8a / ext4 errors=remount-ro 0 1

Something is not right with the filesystem and I am not sure how to fix it.

Thanks

I would like to tar up some system logs with core files as a normal user through a script. However these core files are owned by root.

Of course I get "cannot read directory ...: Permission denied"

Is there a good way to grab these core files through a script? From searching around, I get that the best way is to modify the sudoers file, then run the script with sudo. Is this considered the safest and best way?

Thanks!
