SUSE :: No Permissions To The Filesystem?
Sep 27, 2010
I'm having a chain of problems, one coming faster than the last. Finally, when things started to brighten up - this happened:Booting into OpenSUSE 11.3 64-bit results in an error where a terminal crops up and attemps to load the kernel, however, it seemingly doesn't have permission to do anything other than load the actual kernel. It can't read the login info so none of it works, and during boot 203 warnings but 0 errors are generated, complaining about the inability to read, or write, files.The booting is customized, because the partition table is gone.Little bit of history lesson behind what happened here:I always used Ubuntu and Windows. Ubuntu was my primary OS and Windows was the secondary. Now, Ubuntu did what it usually does which is to **** up hardcore and suddenly not only suggest, but on its own complete, a partial OS upgrade, removing the kernel and various other nasties.
Recovery mode and older kernels still work, but I got so unbelieveably tired of that bothersome crap I decided I'd do away with Debian and switch to RPM in the hopes that it wouldn't do that. I also wanted to try KDE, and since Kubuntu is... well, an abomination that shouldn't have existed in the first place, I decided to give OpenSUSE a go.I try to shrink my Windows partition, but it's impossible. Some kind of important system file has been located at the very end of the partition and it resolutely refuses to move. To fix this, I get EASEUS Partition Master to shrink it. This works, but it also corrupts/deletes the Partition Table so that ONLY EASEUS Partition Manager can now read it - not even Windows' built-in partition manager works anymore. In order to solve it, I can pay $55 for another program called EASEUS Partition Table Recovery Tool.Haha, yjeah - not gonna happen.
However I don't really notice this until I plop my OpenSUSE 11.3 DVD into the computer and start installing, and notice the complaint from YaST2 that it can't give me a decent suggestion because it can't figure out what the hell's on the drive. Manual specification still works, however, and I manage to install it, only to have YaST2 complain at the end yet again that it was unable to install GRUB. Rebooting throws me directly into a command prompt.So I spend days figuring out how to work it with GRUB and finally figure out how to find the UUID's manually and specify a GRUB2 setup that I then manage to chainboot Windows 7 and boot into both Ubuntu and SUSE.All of it works fine, except SUSE, which has this quite horrific permissions problem, despite SUSE being the root of the file system and Ubuntu being mounted inside a home directory of the SUSE partition (incase that has any effect) - although the two user accounts have the same names and passwords.

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)
[code]....

we have a data transfer network drive, shared via nfs and samba.But now I got the special demand to make any of the files read and wirteable, regardsless of the permissions they had before.With acl I get the right permissions (via default values) but the standard unix permissions overwrite this. e.g. when I have 644, it does not care that the group has write permissions)Does someone have an idea (except chmod via cronjob )

Is there a way to revert to default permissions using chmod, for root filesystem? As root I accidentally chmod'd / to 755, luckily this is a dev server and not production so its not critical to fix for me, just wondering though....

As the title says, I've just given ubuntu full filesystem permissions. I used the following command thinking it would change the permissions of the folder I was in.
sudo chmod -R 0777 Is there anyway of reverting the permissions without doing a full reinstall?
However saying that, i'm doing a full reinstall just incase.

I'm trying to mount a remove filesystem onto my own server. I am able to do this, however I can only access it as root, or if I chmod 777 the lot. Obviously I want to be as secure as possible, so I'd like to avoid either one of those options. Another option is to mount it directly into my home directory, but previously when I was trying out Ubuntu this caused Samba problems - and I was advised mounting in my home dir was a workaround rather than a proper fix.
I have root access with sudo on my own server. I've not set a root pasword, and until I need to I'll avoid it. I have a user account with full control over my own home directory on the remote server. I am mounting using fstab - sshfs#username@remoteserver:/media/sdk/home/username/ /media//remote/ fuse user,idmap=user 0 0
What I would like to do is without changing the permissions on the remote server change the permissions when they are mounted on my own server. I would like them to be in the group sambausers for example. Instead they are owned by root and in the group of 1024 (which I have not set). Additionally for this to work they would have to have 770 on my home server and 700 on the remote server....

I am trying to run a cron job as an oracle user. I put the user in the cron.allow file but it still won't run. Other users are able to run a cron job though. I think it's the way the oracle user was created and I wanted to recreate it. However it owns a lot of other file systems as well as the database. Is there a way to recreate or reset the oracle account without impacting what is currently in place?

On my Suse 11.1 computer, I'm only able to run 'mount' as root, but this screws up the permissions somehow, in that my external drives are now read only when I am normal user. I can plug my external drives to my mac osx laptop via usb or firewire, and I can read,write, and execute. As su, I can mount the drives using usb on my suse computer, but only as read only.
Optimally, I want to edit the fstab file to auto mount these external drives, and then have samba run to make the drives available (i.e. rw) on laptop.
NOTE:
1. I created the file systems on a laptop (mac osx) which has different user name than my suse 11.1 computer.
2. I tried to use chown to manually force user:group to be Mike:users instead of root:root, but the external drives still are 'read only.' Trying different options in column 4 fstab file kept giving same trouble, but I can now get user:group = 99: 99 (not sure what that means).

/etc/passwd permissions keep getting reset to 600. When I set it to 644 as su, it eventually changes back.This occurs on my openSuse10.2 machine but not the openSuse 11.1 machine, but I assume that is irrelevant. Is there something that got tweaked that I need to change in Yast to stop this from happening?

My mac osx hard drive does not boot anymore and I would like to get my important files off before I reformat the hard drive. I have run into a bit of an obstacle -- there seems to be some permissions setting that are barring me from accessing the files I need to. I can see the Machintosh HD and can access some files. How do I change permissions for the entire drive and all it's directories?

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?

When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.

I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.

I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

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?

Problem: 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?)

I bought this laptop several years ago. It had Vista. Just long enough for me to download SUSe, nuke and pave the HD and install Linux. Recently I upgraded from 1 GB to 4 GB of RAM, the maximum that is allowed given the motherboard (based on from what I am able to learn the Intel 945 chipset).
After upgrading to 4 GB, the machine (according to "My Computer") only sees 2.9 GB. I understand that under an earlier version of the BIOS that the machine would not recognize the RAM correctly. Additionally the "My Computer" page lists the display as "Intel 945GM". My problem is that I can find no Linux utility to flash the BIOS on this machine-- Toshiba only provides the BIOS included in an .exe file for either XP or Vista. I am hesitant to use the BIOS for the Intel 945 series motherboards from their site.

I am running memory test on SUSE, Memory test is just writing some patterns into a memory and reading it back in all CPU threads. After a while, when memory test is running in the background , I am trying to reset the system by echo b> /proc/sysrq-trigger command, Upon SUSE warm reset , I am seeing some UNCORRECTABLE MEMORY ERROR in model specific register (MSR : 0x421),
I am seeing this behavior on one of my server which has huge amount of memory.,Have you ever seen this UCECC error when SUSE generates warm reset when memory test in the background ?

I've got several language multimedia CD-Rom's, made for Windows 95/98/98 SE and 2000, that I'm using by means of my daughter's old PC (Win 98 SE O.S.). However I noticed, also, that you can perfectly use them even with Windows Vista. What I'd like to know is if you can use them even with Suse/Novell and (why not?) OpenSuse Linux.

I am new to Linux and wow, it did not take me long to run into a huge snag. I am running Suse Linux Enterprise 10 on a laptop and by some strange reason the computer froze from overheating and I was forced to shutdown improperly. Once I restarted it booted right to the command prompt when it usually instead boots to the default user. I managed to get gnome running using the "startx gnome" command. But when gnome loads, none of my normal extentions load like my wireless driver, the sound driver, etc. how to restore gnome to automatically load the default user on start up or fix any other damage I might have done? lol

how to install a D-Link Access Point on Suse 11.0 or steer me toward documentation that will do that? I configured the device on XP following instruction from this forum and the AP configured perfectly.The AP is plugged directly into the network port on the computer. It *should* function correctly without a router. I tried a restart and Suse has no idea it's there. The computer is currently configured for a wired connection which needs to be changed. The computer itself is going to be used as a small home storage server.
