View 1 RepliesI am trying to run matlab 7.7 (R2008b) on my ubuntu 9.10 distribution..the thing is that I am totally new with both matlab and linux and I get the following error message from matlab when I try to run an example mex-function:
>> mex yprime.c
/home/margareta/Desktop/matlab/bin/mex: 1572: gcc: Permission denied
Warning: You are using gcc version "". The earliest gcc version supported with mex is "4.0.0". The latest version tested for use with mex is "4.2.0". To download a different version of gcc, visit [URL] eval: 1: gcc: Permission denied mex: compile of ' "yprime.c"' failed. Error using ==> mex at 213 Unable to complete successfully.
I had gcc-4.4 as default on my pc, so after this error I downloaded an older version (gcc-4.1) and removed with rm the symbolic link in /usr/bin pointing to gcc-4.4 and created a new one pointing to gcc-4.1. Now when I type gcc -v in the terminal it says that gcc is in the packages gcc and pentium-builder, to do an apt-get install. I tried that but than it says that gcc-4.1 is already the newest version. It seems that I have multiple versions of gcc installed but neither the terminal nor matlab can find them.
I am attempting to make a backup copy of a file, but every time I try to copy the file, I get a "permission denied error -- even when running as root. The file is on a volume mounted as /media/Data . No problems reading/writing other files on the volume.
Here is the info on the file:
-rw-------. 1 root MailServer.img
I've tried chown but get the permission denied as well. This is a virtual machine image that runs fine, but even with the VM completely shut down, I get the same error.
I just noticed on my Ubuntu machine (ext3 filesystem) that removing write permissions from a file does not keep root from writing to it. Is this a general rule of UNIX file permissions? Or specific to Ubuntu? Or a misconfiguration on my machine? Writing to the file fails (as expected) if I do this from my normal user account.Is this normal behavior?Is there a way to prevent root from accidentally writing to a file (Preferably using normal filesystem mechanisms, not AppArmor, etc.)
I understand that root has total control over the system and can, eg, change the permissions on any file.My question is whether currently set permissions are enforced on code running as root. The idea is the root user preventing her/himself from accidentally writing to a file. also understand that one should not be logged in as root for normal operations.
the terminal and logged in as root i was changing file permissions and happened to change the root folder to 700. Now my icons have gone and i can't even access the terminal.
I was just wondering if it is possible to go to rescue mode using the cd and restore all the appropriate file permissions to root/ users if possible
I am very new to linux. I just got the dual boot working a couple of days ago. Now I downloaded MATLAB (2009b) from my university website. It came in a zip file...well I have no clue how to install it. I looked at the instruction manual, it doesn't really explain much.
View 5 Replies View RelatedSince I installed MS2 I messed up grub. Finally I got 11.3 back to its old glory.
What would be the best procedure to create a backup image with all settings and permissions ...just in case ?
I installed MATLAB R2009a in my laptop (Fedora 14 x86-64), the installation was succesful but when I run MATLAB (in a console), appears a message: error while loading shared libraries: libut.so: cannot enable executable stack as shared object requires: Permission denied
I find a "solution", execute in a terminal: execstack -c libut.so
I used several times with differents libraries that I needed, but I run MATLAB in a terminal, MATLAB starts in a terminal, only a prompt ">>" and nothing.
I have downloaded iso image of matlab provided by my school. As I mount the image using gmount, I saw number of files. One of the file name is 'install'. I imagine this is the file which will initiate the installation process, but don't know how to use it. Do I have to go to the mount folder in terminal and type sude install ?

View 2 Replies View RelatedThe root user of Linux doesn't have permission to read/write a regular file, unless all users have permission to read/write this file, like below:
drwxrwsrwx ....... file_name
However the owner of the file can still read/write this file.
AND:
0) not the problem of execution, just read/write
1) not the problem of device because regular user can read/write it.
2) the result of command id:
uid=0(root) gid=0(root) groups=0(root)
so I don't think it's the problem of group.
I understand at least some of the advantages of this multi-user set-up, but why would you have to become root to stick a DVD in the machine? I suppose I could go into root and chmod the mount command, but - why would it have been set up that way at all? Is it paranoia?
View 5 Replies View RelatedWhen I installed OpenSuse 11.2 it mounted I configured to mount all of my windows/NTFS partition. However, one problem is that only root can write to it. I was trying to change it to '777' permission. However, as root I can't change permission. chmod doesn't work and neither does using nautilus (as root) work.I even tried unmounting it and then doing a chmod. That didn't work either.

View 7 Replies View Relatedwant to run VirtualBox with root permissions. Trouble is that only when run as root i can access attached USB devices inside of a virtual machine, otherwise, these a greyed out).Now running VirtualBox as a root user also changes the configuration folders, making all my virtual machines already defined disappear. I also don't want to copy all to the root configuration folders. Is there a way to give the VirtualBox root permissions but without actually running the application as a root user. Is it possible to do without changing the permissions of the non-root user, i.e. i don't want my user to have all root permissions, due to security considerations.

Updated from Ubuntu 10.10 to 11.4. Boots only to grub. 11.4 Live CD results in very distorted video so option of reinstalling Grub 2 is not available. Since 11.4 Live CD has such bad video I want to go back to 10.10. Notebook system has one drive and no windows install. Live CD boot from 10.04 works with clean video, but when I try to copy filesystem /home/username it won't let me because I don't have permission. Properties says I am not owner so I can't change permission. Can someone tell me how I can get permission required to copy files in filesystem when booting from Live CD? Sudo command under terminal of Live CD appears to have no effect on harddrive filesystem files I'm trying to backup.

I'm using ubuntu 11.04, I'm having some problem of ownership while sharing folder/files. to share i change the folder share option:1. Share this folder, then followed by 2.allow others to create and delete files in this folder3. guest access.Now if someone in my local network edit any file and save it, it gets locked. if some one copy their file in this folder the permission is marked as "no group" "no owner". and they get unaccessible to me. i tried doing chown <user> <folder> but it says Operation not permitted. Now how i can possibly share my folder on local network so that they can be edited by others without getting locked down , if they copy files i can able to modify them.

Everything in Linux is a file, right? And everything can be represented by a file? Is there some way I could create a block device file that represents (i.e., provides an interface to) this image file? If so, then I could use fdisk on the device file to split it into partitions, format the partitions, and then mount them as directories. I could create a file system within a file system, which would be fun.
