General :: Remount Root Filesystem As Read/write After Modify Readonly-root File?
Dec 21, 2010My linux distro is CentOS 5.3. Today I edited /etc/sysconfig/readonly-root and set "READONLY" to yes, now my /etc/sysconfig/readonly-root file is like this:
# Set to 'yes' to mount the system filesystems read-only.
READONLY=yes
# Set to 'yes' to mount various temporary state as either tmpfs

Ubuntu :: Remount A Usb Drive With Nautilus In Lynx?
May 8, 2010After using "safely remove drive" on a usb drive automatically mounted (in lucid lynx) i no longer have the ability to remount that drive without cycling its power.I don't know if it has anything to do with removing the "unmount" option from nautilus in favor of cleaning up menu.Anyway I didnt see any forum posts on the issue ---ps. anyone have trouble using a proprietary gfx driver (nvidia for me), a custom console resolution (specified by grub), and the splash screen - when trying to access the ctrl-alt-function tty's?seems the resolution is all screwed up or something and i cant see the login prompt. disabling splash via grub fixed it fine (EDIT - did not fix it)
View 7 Replies View RelatedUbuntu :: Remount Cdrom With Unhide Option
Aug 16, 2010I'm trying to install WoW on my Ubuntu machine and I'm having trouble right off the hop. I'm using an install DVD thru wine and it says since the Installer.exe is hidden I need to remount my drive with the unhide option on.
I'm following this guide [URL]
This is the part of the guide I'm getting stuck at
Note that on some WoW DVD's the installer executable is hidden and you need to re-mount the disc with the 'unhide' option. To do this type in a terminal:
sudo umount /dev/cdrom
sudo mount -t iso9660 -o ro,unhide /dev/cdrom /media/cdrom0/
The unmount part works just fine but when I go to remount the drive it gives me this error:
mount: mount point /media/cdrom0/ does not exist
General :: How To Remount The Grub
Nov 14, 2010I used the Ubuntu 8.04 disc and went to the terminal, got the grub prompt and followed the couple of lines to setup Grub on (hd0,0), which I confirmed through Fdisk was the location of the boot. I also used my gParted CD to check the partitions and on gParted it is marked as hda,a. The flag shows it is an active boot, as does the * on the Ubuntu terminal show. I am getting the "..exist...no" message. I have xp32 on hd0,1, 64 on hd0,2 and ubuntu on hdo,6.
The machine was working properly and then it was stored for a year. It works fine with the live cd and I have the GRUB shell, which lands me at the GRUB prompt. I am assuming that the kernel is not mounted ? (whatever that entails, as GRUB one message said I had to install kernel before.....
Anyway, I remember that installing the three systems was quite grueling, as I first installed 32, then changed the boot ini file, and then installed 64 and changed the boot ini file there, and then installed ubuntu - with great trepidation- as it seems to want to partition my discs, which I pre-partitiond with gParted. I guess I could copy the GRUB text and the Windows text from another machine that has the same basic install, and redo it.

View 3 Replies View RelatedUbuntu Security :: Constantly Having To Remount Encrypted Home Folder
Aug 16, 2011while since I've been here. I'm having an issue with a fresh install of 11.04. Due to work requirements, I encrypted my home folder, which is fine, however, it seems to randomly lock itself down while I'm working, and it's getting really annoying.
Apps stop working, I can't open nautilus (something about not being able to create certain folders because home is locked), hell, even the terminal link on my desktop says failed to launch application (though the launcher on the top panel works). I just have to run ecryptfs-mount-private and enter my password to fix it, but it's doing this every 15 minutes or so. what might cause it to relock itself so frequently? I would expect to not have to deal with mounting my private data, that should happen at login and be good until log out.
OpenSUSE Install :: How To Remount Encrypted Home

Slackware :: Kernel 2.6.33 Failed To Boot (Cannot Remount Read-only Fs)
Mar 7, 2010I tried to compile a 2.6.33 kernel following Alien's guide.
I pretty much used the default values for every (NEW) option avaiable. I used "make localmodconfig" on my current config (zcat /proc/config.gz) and then tried to use "make menuconfig" to check if I could change anything. I didn't understand most of the options, so I skipped it. Then I used "make bzImage modules" and "make modules_install", copied the files mentioned on the wiki and run lilo.
But when I try to boot using my custom kernel, it gives an error like "Cannot remount read-only filesystem as read-write! This can cause serious problems."
If I try to continue the boot, it hangs when trying to launch the syslog script...
The new kernel entry on lilo.conf is:
Code:
image = /boot/vmlinuz-custom-2.6.33
root = /dev/sda4
label = newkernel
read-only
just like the default kernel entry.
By the way, one thing I changed is the kernel compression format, which I set LZMA. But it didn't seem to be the problem, since it at least started...
CentOS 5 :: Remount Second Hard Drive After Replacing Primary?
Jul 27, 2011For starters, I apologize if this turns out to be a double post. My windows laptop hiccupped in the middle...
So I had a Linux box with two drives running happily for years. Both drives were in the same logical volume, and the second had a file system on it.
The the boot drive croaked. I replaced it and reinstalled CENTOS (making sure, of course, to be careful to use the new drive). The I put the second drive back into the volume group (and that's it).
I'm assuming I probably need to create a new logical volume, because that's how it was before, but I really really don't want to format it.
Am I missing a step or am I screwed?
Fsck -l showed the following output both before and after I put the drive in the volume group. code...
Ubuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?
Jun 9, 2010my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Ubuntu :: Root User Directory Does Not Exist, Root Password Not Recognised?
Oct 26, 2010I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.

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.

When I wanted to delete the folder I didn't have permission so I ran "gksudo nautilus" so I could delete it as root. So I deleted the folder but I did not get the space back!
I went to /.local/Shared/Trash and one of the folders I deleted was there but deleting it didn't get that space back either.

Ubuntu :: Make A Shell Script Run With Root AND Non-root Priveledges?
Jul 28, 2010I have a bit of a dilemma.
I'm using XFCE and it doesn't by default lock the screen before hibernating. I see this as a bit of a security risk, and as I can't hibernate while the screen is locked, I'm a bit lost as to how to achieve this.
I've begun editing /etc/acpi/hibernate.sh, here's what I have so far code...
If I run with sudo, the system hibernates, but gnome-screensaver will not fire. I can verify this by trying "sudo gnome-screensaver-command --lock". The screen goes black, but is not locked. The screen locks properly without sudo.
So the only solution I can see is to edit /etc/acpi/hibernate.sh in such a way that gnome-screensaver-command runs under the current user, and pm-hibernate is called as root.
Also, when I click the HIBERNATE button in XFCE, how does it call pm-hibernate under root without prompting me for a password? I normally wouldn't be interested in such things, but as it seems relevant to my problem I'm a little more eager to learn

View 3 Replies View RelatedDebian :: Root Access And Desktop Disabled \ Couldn't Open The Root Terminal?
Feb 19, 2011I was using the latest stable release of Debian, dual-booted alongside Windows Vista, with the GNOME desktop, installed via netinst, trying to build and install a library that I knew and trusted, when suddenly I couldn't open the Root Terminal. I clicked the link (in Applications->Accessories (I think, whatever the top one is)->Root Terminal), and in the taskbar I saw an item that said "Starting Root Terminal". A few seconds later, that went away, but the terminal still wasn't open. I tried the regular user terminal, to see the same thing happen. Unsure of what was happening, I tried restarting my computer, since that's always the first step you should take in computer problems.
When I restarted, GNOME wouldn't start. The screen would flash a bit for a few seconds, then a dialog box would appear over a background of static that said "The greeter application is crashing. Attempting another one...".t would then go back to the DOS-style kernel, wait a second, and then the same thing would happen. After several of that, I would get a blue screen which said something to the effect of "It has been detected that the desktop environment has crashed six times in the past 30 seconds.
Waiting two minutes before trying again." When it did that, I tried logging in as root to assess the problem. I gave it the correct password, but it said that it was an incorrect login. After several tries (to ensure I didn't mistype the password), I logged in as myself. Same problem. I tried the su command, with the correct password, and it said it couldn't authorise it.
After a lengthy conversation with a friend of mine who was very good with computers, he basically summarised that he had no clue, but that his best guess would be a virus. Upon running the Linux installer, I found the Repair option. Not being particularly familiar with Linux, I used it simply to backup my important files onto a flash drive. I then tried running the Install option, in an attempt to simply write over my existing Linux and make it new again. The installer, however, consistently froze up when trying to start the partitioner, on the "Checking disks..." stage. I figured it was a problem with my partition. In my naivete, I simply used the Windows tools to clear that partition... It destroyed GRUB too, so I couldn't run any OS. I figured my computer was pretty well screwed, and at that point just decided to bring it into the shop and have them completely wipe it.
my computer was backed up onto an external hard driven I brought it back, I reinstalled Windows. Upon restart, it said that it was still looking for GRUB, which made no sense to me. After messing around with it a bit, I decided to just reinstall Linux too. To my lack of surprise, that fixed the problem. Both OS' now ran just fine. The first thing I did on Debian was to install the Clam Anti-Virus, which I understood to be one of the best Linux anti-viruses. However, within about 10 hours, got the same problem as originally. I wasn't doing any of the same things, and between the lack of consistency in activities and the fact that I had an anti-virus running,figured it wasn't a virus. Not knowing what to do, I just left it and have been using Windows since.
