I am trying to use a second sata 3.5 HD and at other times a USB 2.5 HD. Both prove a pain to use because Ubuntu tells me their permissions can not be be determined. They have only been partitioned to ext2 on Ubuntu. This happens on 9.04 10.04 and 10.10
I have searched the web about this found many answers which just do not work.
I just did a fresh install of Fedora 11 and added Raid 1 for two additional drives during the install,
So, I have 3 drives. One with the OS, that I boot from. /dev/sdc
Then 2 others in a Raid 1 config, /dev/sda and /dev/sdb -- those are in /dev/md0
Everything with the system is fine. I can boot up, and everything runs great. So then I try to view the Raid and it looks ok when I open 'Computer'. it shows the main OS drive, and what looks like the 2000GB raid drive. So i open it and just see a 'lost+found' folder. Not surprising, b/c I haven't added anything to it. But when I right-click I can't create a folder b/c it's greyed out, I can't drop files in there, and when I get Properties on the drive itself it says 'The permissions of {driveid} could not be determined.'
My external hard drive has all of a sudden decided that it wants to be read only, meaning I can not add files to it, delete files, or even move them around. WHen I try to check the permissions, I get the error that permissions could not be determined.
I've tried changing permissions through the terminal using "sudo chmod u+w /media/filessystem", but I only get the message back "chmod: changing permissions of `/media/filesystem: Read-only file system".
I don't know exactly whats wrong, it won't play DVD's or recognize that a DVD is in it. I checked in terminal with sudo lshw -c disk, it shows the correct info for the drive but still says status:nodisk.Double clicking or right click>open doesn't do anything either. Is there something I'm missing? Whats weird is audio CDs are recognized and will play just fine.(checked with multiple DVDs
View 2 Replies View RelatedI had a problem after an update and ended up re-installing Lucid. Now I don't own any of my hard drives. In the "Permissions" tab of properties they say "The permissions of "*" could not be determined". This is becoming a real problem as my the hard drive that has my Home on it is in "disc failure is imminent" mode and I need to copy everything to another drive urgently.

Is there a relatively simple way to automate this?
How is the super user determined for the dialog box that pops up when trying to perform administrative tasks, "An application is attempting to perform an action that requires privileges. Authentication as the super user is required to perform this action."? Does it always ask for the password of the default user created during the OS install, or should it prompt for the current user's password if that person is an administrator?I use likewise-open for windows domain authentication, so I typically log in as a windows user that likewise-open has added to the list of users on this system. I have given this user sudo access and added the user to all the same groups as the default user, yet whenever I perform an administrative task in gnome I am prompted for the password of the default user. Is this normal? It seems like the behavior would be to ask for the current user's password if that user is an administrator, and if so what determines that the current user is an administrator?

Code:
/var/log/messages.1
/var/log/kern.log.1
/var/log/daemon.log.1
/var/log/messages
/var/log/kern.log
/var/log/daemon.log
/var/log/syslog

How do the group-ids for the devices in /dev get determined during boot up? The system must get the defaults for the devices some time during the boot process. Where are the defaults listed?
Actual reason for my question is that I need a permanent change of "dialout" to "uucp" or, even better to "dialout,uucp" in this line:

I am wondering how I would go about creating a .deb file that would extract it's contents to two different folders. I would have one file directory that should be extracted to /opt and I have a second that should bextracted to the current user's home folder and /etc/skel - How would I go about doing this?

View 2 Replies View RelatedProblem: permissions for rsync and BackinTime. Setup: Ubuntu 11.04, Two internal HD, #1=main, single boot, #2=backup drive. Question: How do I set up my 2nd HD with correct permissions? Background: I had previously a dual boot XP+10.04 with a 2nd HD formatted as NTFS. With this I was able to use my rsync and backintime to my 2nd HD with no issue. My new set up is EXT4 on both HD.
(I even tried to reformat my 2nd HD as NTFS, but that didnt fix the issue) I followed [URL] to mount the 2nd HD and get permissions. But now when I run backintime i get this error: [E] Error: rsync: opendir "/home/myhome/.ssh" failed: Permission denied (13) I did my requisite reading for a newbie, and am stuck. I ran backintime as root, and it backed up ok. How do I run my user version of backintime? (i.e. How do I fix the permission issue?)

View 6 Replies View RelatedI have been reading online help all afternoon, and it has really helped me on setting up virtual hosts but this one confuses me.I appreciate that 'root' is not enabled for login and the recommendation is that it should not be. I also understand sudo to elevate myself to root equivalent to do admin tasks.However, I would like to use an FTP client to edit some of the files on the server but sudo obviously does not work.
At the moment I have to use sudo vi <filename> I would really like to FTP onto the server, download the file, edit it and re-upload it. However as an FTP user I do not have write permission to the files.

I recently got a T-Mobile Tap and I've been trying to connect it via USB to my laptop running Lucid.When I open up the icon that shows up on my desktop after connecting it, I can't run the setup files inside. It says: The file '/media/HUAWEI/checksetup.exe' is not marked as executable. If this was downloaded or copied form an untrusted source, it may be dangerous to run. For more details, read about the executable bit.When I try to change the permissions from ready only, I get: Sorry, could not change the permissions of"checksetup.exe": Error setting permissions: Read-only file systemCan I tried calling T-Mobile but they said they don't troubleshoot with Linux. They said it's an "older operating system".
View 2 Replies View RelatedI just installed Ubuntu workstation into VMware and then installed Apache, Mysql, PHP, and phpmyadmin.I am able to access Apache from any computer in my home so there is not issue there.The issue I am facing is when I try to copy anything into /var/www/ I get a permission denied messsage.I added myself to the administrators group and then rebooted but still get the same message.
I was able to access it by using the following command...gksu nautilus.I don't want to have to do that every time. I would like to be able to access it by just opening "Documents" and the selecting "file system" inside of Nautilus.
I have 4 hard-drives in my tower.Hard-drive 1 contains all the system files.
hdd 2 contains all music
hdd 3 contains video
hdd 4 contains misc data
The root of the system "/" is on drive 1, and I used fstab to mount hdd 2 - 4 under /storage/music /storage/video and /storage/misc I want /storage/misc to be readable and writable by people on the LAN. The other 2, I would like to be "read" only.
what should I set the permission of /storage to and what should i put /storage/misc to.If I put /storage/misc to 777 (chmod 777 -R /storage/misc), will people ever be able to go up the "tree" and ever get access to "/"?
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 recently got an old computer to use as a server and I have a whole list of things I want to do on it, but I'm having difficulties.When I installed the server, I installed AMP, FTP, Samba, CUPS, and some other items. I made a user account called 'nessdan' which (currently!) is in these groups:
www-data adm dialout cdrom plugdev lpadmin sambashare admin
The www-data group was added because I wanted to FTP my site files into '/var/www/' . Okay, that ended up working out for me. This is where things got sticky. I installed PHPMyAdmin and the files went to '/usr/share/phpmyadmin/' . I wanted to install a new theme so I downloaded it onto my Laptop, then logged in via FTP but couldn't transfer files into there! It turns out the folder was owned by 'root' and was in the group 'root'. The only thing I could come up with was to change that folders permissions so the owner was 'nessdan' and the group 'admin'. I was going to do that to the entire /usr/share/ folder but I didn't know whether or not I should be changing the permissions in the first place.
But the the trend continues! I have my print server setup and working but I wanted the server to hold the Windows drivers, so I went to '/var/lib/samba/' to do some work but noticed that a lot of the files' permissions were locked down to read only and the owner and group were 'root' . I ended up doing a 'chmod 775' and changing the owner and group to 'nessdan' and 'admin', respectively. Well I transfered over the files but now the service nmbd isn't working. The good news is, I expected to mess something up along the way and had already planned on reinstalling Ubuntu Server 10.10. I've only had the server for 4 days now and I knew from the beginning I'd be wiping it clean. I want to know how to set this thing up proper and the biggest problem is getting access into folders so I can FTP into them.When I do wipe my PC clean and start anew, how should I go about the changes that I did before (PHPMyAdmin, Samba Driver Folder)?
I need to add some files in /usr/local/include but the folder properties says "you are not the owner"

my dvd-rw was not working. but i had to install linux. so i installed ubuntu from the iso using demons tool.

How can i become the root?
