General :: Changing Permissions To Allow Virtual Box To Start Without Error?
Jan 15, 2010
I installed Sun's virtual box 3.1 under Ubuntu 9.04. It worked flawlessly. I upgraded to to 9.10 and know I get a kernel error. rc=-1908 Now I cannot get Windows to load.
I 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)
Finally I managed to install my printer/scanner drivers.The last thing I need to do is to add the following two lines to 40-libsane.rules (which is a read only file):# Brother scanners ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes".How can I change permissions for this file or add these lines without changing permissions?
I am trying to automate ftp to transfer files from windows to Linux server automatically and my script looks like this .
@echo off SET CUSTOM=/apps12i/oracle/KIRAN/apps/apps_st/appl/custom/12.0.0/reports/US echo user oracle> ftpcmd.dat
[code]....
Any files we transfer through ftp from windows , their default permissions to be set 755 automatically . We are using Red Hat Enterprise Linux AS release 4 (Nahant Update 7) .
My Torrents will not start due to a "Permissions denied" error.The folders with the files being download have it set 777, so I'm thinking it's something else.When I look at the auth log, It does appear that it is that folder causing the issue.I can keep guessing the cause of permissions, but I do not know how to trace the problem.
I first installed linux as ubuntu version 9.04 straight off of a Computer Active CD and liked it so started to delve into file permissions and authorisations, simple stuff I suppose just so I could feel my way around things for a while. Using the built in Ubuntu software centre I downloaded and installed a prog which handles authorisations and I found that very helpful but then through the update manager I installed the latest distribution update (9.10) and now find that the authorisation software only lists a couple of things that I can get to and consequently every time I mount one of my hard disks I'm asked for my admin password even though I am logged in as administrator which is a hassle,
a small one but there all the same, as a newbie I realise it must be me not understanding something but I just dont know what, also in the previous version right clicking on the logging out panel gave you an option to remove the 60 second shutdown or restart delay and that has disappeared in the new version, again its really only just a nuisance thing but I find that sorting out this sort of thing will help me to understand the system
I run a small site and today I've discovered that my site is down. I found that cPanel has flagged the account suspended even though I haven't got any quotas on the account. I don't know what went wrong. I've tried to unsuspend the account in WHM but a certain part of the function failed.

After searching the internet someone mentioned that the problem might lie in the permissions of the public_html folder. I had a look at the permissions and the folder had no permissions d----- When I try to chmod the folder I get this error:
Quote:
chmod: changing permissions of `public_html': Operation not permitted
I have no idea what to do next. All the files in the directory are locked too. I tried to move them but this command isn't allowed either. I ran these commands under the 'root' user in SSH.
my iwlist scan is normal. ethernet connection ok, wirless not working but does seem to receive. wifi radar lists my router ssid. Does this say I have the correct router for my wireless is my question? I am also getting this error message with this system on KDE, LENNY. From KWLAN a wpasupplicant front end.
"you do not have permissions to start pppd or pppd was not found. Dial up networking will not work."
I have an Ubuntu development server and a Windows 7 workstation. I use Windows Gvim to edit files on the linux server, over a samba connection.Saving files from Windows change the Linux permissions in weird way depending on the Windows app I'm using and also depending on whether there's a file extension or not.Here are some testsNo extension; Notepad2: 644 to 764
matt@mattserver ~ % ls -l testfile -rw-r--r-- 1 matt matt 0 2011-05-28 07:09 testfile --- Save from Windows Notepad2 over network ---
How do I program a virtual machine to auto-start/boot upon boot up of the host system? I am experimenting with SNORT network intrusion detection system and have installed it inside a virtual ubuntu box which I want to start automatically.
One of our client was complaining that their server was down and mysql and apache services were down. The server is Ubuntu 8.04. When we checked, the permissions of /etc/init.d/mysql and /etc/init.d/apache2 were changed to 644 from 755. How could this be possible?I need your valuable suggestions on how can i monitor whether any malicious intrusions or scripts are running.
The problem is whenever we reboot the system the permissions of / dev/lp0 (line printer) is changing. So every time we are changing the / dev/lp0 permissions through root using chmod 777 /dev/lp0
Is there any smooth solution for this? Why the /dev/lp0 permissions are changed with every reboot?
I'm new to KDE and am running KDE 4.7.1 on top of Arch Linux. It's fantastic however I have one problem - virtual desktops. Yeah I know there are those "activities" things which people say replace virtual desktops and I will look into them, but for the moment I want to stick with what I know.
And it's almost set up too. In fact, it is, apart from one issue: Say I'm on desktop 3 and I click on the desktop (as in - the bit with my wallpaper, etc, not the little square in my panel) - it immediately switches to desktop 1. Got no idea why I'd want it to do that and it's bugging me.
im looking to allow virtualbox raw disk access to /dev/sdb
currently if i
ls -l /dev/sdb brw-rw---- 1 root disk 8,2010-01-04 17:00 /dev/sdb
now if i chmod this to 777 or use chown to change the owner this temporarily works but after a few moments it defaults back to its original permissions.
is there a way i can define the permission? i was thinking fstab but i can't have a mount point?
I often run "gulp", a networking utility, to capture data from an instrument on "eth1". By default gulp must be run as root to have access to the ethernet port, and when I'm the only one running it, that's fine. But I need to let several other users to capture data and don't want to give them all sudo permissions for both gulp, and more importantly, 'chmod'. Is there anyway to change the permissions of eth1 to allow all users to open it and avoid sudo entirely? This is on a Red Hat/Fedora machine.
I've compiled my own code as root (long story why) anyway I now need to switch this to a normal user to compile. So I did a simple copy/paste (using gnome/debian lenny) to my home/user. I then logged in as used to see the folders with a padlock and permissions for root only. So I logged back in as root, change permissions to the used, check they were all ok, logged back in as user, and it still says owner root, even thought when I log in as root it shows user as owner.
I need to make my 1st ever script to backup VMware workstation VMs to a folder which is then backed up offsite. Here is what I have so far (will be croned):
Code:
sudo vmrun -T ws stop "/home/gareth/vmware/NagiosWeb/NagiosWeb.vmx" soft sudo vmrun -T ws stop "/home/gareth/vmware/UbuntuBackup/UbuntuBackup.vmx" soft **copy or rsync to /home/gareth/vmware-backup/ dir**
[code]....
1. Just to confirm, I need to place the above in a file with #!/bin/bash at the top and make it executable.
2. How do I know when the VMs have safely shut down so I can start the copy? I guess I can either a. wait a specified amount of time b. run some sort of if statement to confirm they are off.
3. How do I use Rsync or cp to copy to the backup folder?
4. How will I know the copy is complete so that I can start the VMs again?
I use a USB drive to store most of my personal and work files, and I use it both at home and at work (two different machines, both running Ubuntu). The drive is encrypted, and is accessed using TrueCrypt (the entire drive is encrypted as a device rather than an encrypted file on the device). The TrueCrypt device is formatted as ext3/ext4.
I have a problem with certain file permissions being changed to read-only (rw-r--r--) after mounting the drive. This happens after I have used it on one computer, and then I mount it on the other. Even though I have been setting write permissions to all (chmod -R a+rw *) to get around this problem, when I mount on the other machine the write access is gone. I don't want to keep manually changing permissions; I would like the file permissions to stay as I set them.I'm using the same version of TrueCrypt at work and at home. I'm running Ubuntu 9.04 at work, and 9.10 at home.I do have different usernames on these computers, and I suspect that is the problem (but don't see why this would change file permissions for all users).
I installed Ubuntu from the alternate cd a few days ago to save space and resources on a very old laptop. (install command line, then add what I wanted) But I have struck an interesting problem with file permissions. Various programs like synaptic, leafpad, pcman, Banshee, all require I enter the root password to execute them (or sudo command from terminal). I want to change synaptic from root ownership to sudo and leafpad etc to execute without using the sudo command in terminal. I could get comments on the commands before I execute them in terminal and if I am introducing a security problem, as I am still learning bash. $ sudo chown sudo:sudo synaptic
I would still be asked for my sudo password before being able to open synaptic? As in standard Ubuntu instead of root password.$ sudo chmod 777 leafpad pcman Banshee All users could open these programs from the menu? I have my admin account and a general account which I use for everyday things like surfing the net and listening to music.
I have two computers (one at work, one laptop) that I use daily. Both are running Ubuntu 10.04. I frequently use a usb stick to transfer files from one to the other. Somehow, every time I do this, all files get turned into executables (as if I did a chmod a+x on them...)
This happens every time I use the usb stick. I've reformatted the stick, but still this problem persists... anyone have any ideas on what is going on? It is really getting annoying to have to zip up folders so this doesn't happen...
I have four internal harddrives on my system. On the first HD i've installed Debian 5.0 AMD. I'm trying to write to my other HD to backup my files,but i get a message that this HD doesn't have permision to be writen to. How do i change the permission for Harddrives.
I have a server running RHEL6 and a virtual machine also running RHEL6. I created a directory /home/data on the server and another on the VM. When I mount the host directory on the VM, I am not able to change the ownership/permissions through the VM no matter what. The ownership is set to "nobody" and I can't even change it to root.
I'm running rhel6 64bit. Accidentally I ran % chmod -R 777 /etc and after that I have a problem to do 'su' or 'sudo'. When I did sudo it complained that /etc/sudoers has 777 while it should be 0440. I changed that and also restored right permission for:
Anyway it failed to 'su'. Then I restored back permissions on files in /etc/security and /etc/sysconfig. Still can't do 'su'. Note: I could login from console as root but can't 'su' or 'sudo'. when I do 'su' it gives error: Password: su: incorrect password
just trying to learn linux here and have some comfusing moments.it is my understanding that if you own directories and files you maychange the group, ownership, and permissions on all of these as you desire.however, in my case I cannot make any changes in my setup on group, ownershipor permissions on any of my files or directories.get error message <operation not permitted>. I know as root you ar supposed tobe able to do anything you desire, however in my case I can go in as root andtry the same commands with the same results. it is as if I am locked out ofsystem as far as any changes are concerned.on my jump drive I have:
I recently got a new external drive and backed all my files up on the new external: movies, music, docs, etc. Now all my files have permission rights to the root only. I was able to change this by open up nautilis from a terminal in root and change the permission on the whole drive to my current user so I can access the files, copy & delete the files. I wanted to change some music file information in Kynamo this morning and was not able to since all the individual files still belong to the root. How can I change this permission issue without having to change each individual file?
Is there a way to have a directory automatically change the permissions of a file that is written to it? I have a program which saves files to a directory, and gives those files read-only permissions to members in the group. This is a problem, because other users of my computer need to be able to edit these files. The directory itself has rw permissions for group members.
I guess what I am looking for is a way for the directory permissions to "override" the permissions the program is trying to save the files as. For example, if the directory has "rw" permissions for the group, then any file saved to it will automatically get the same permissions, regardless of what the program writing the file is trying to do.
