I wasn't doing anything special on my computer (Ubuntu 11.04) when it just turned off. When I rebooted I was presented with BusyBox. I'm still pretty new to linux, but it appears that root is totally empty. Is there a way to view a log before the system crashed?

View 8 Replies View RelatedFor a month or so now, I have been enabling ssh and opening port 22. I cron'ed the start and stop commands to leave them open only a few hours a day. After a bit, I checked my logs to find that some IP or another was attempting to brute force my root account.
I took little real threat by the offense.
(1) my system does not allow root to login and
(2) it would cut them off sooner than later when my system issued the stop command.

Today I log in to find that all of my log files, as viewed from the gnome log file viewer, were empty of entries from about noon yesterday and prior.
Though I haven't noticed anything at all out of the ordinary with my system, I would like to get more opinions on the matter. Would there be any conceivable way that this was an automatic system routine, a clean up action of something? Additionally, if I was indeed the victim of a hack, what can I do to further protect my system (keeping in mind that I do want to access my system via ssh from time to time)?
When I load the disk I can view my backup drive properly but when I try to view my working drive it shows it as being empty. I also noticed that I had a 1 mg unallocated partition at the beginning followed by my ubuntu partition.
I then ran gparted in terminal and it did show the partition as having my system on it but I am not able to perform any tasks. No moving or resizing.
The root filesystem is the filesystem that is contained on the same partition on which the root directory is located, and it is the filesystem on which all the other filesystems are mounted.
In a multi-OS desktop, having Windows, Ubuntu and Fedora, what is the root filesystem as the root directory is located on at least 2 of the OS.
I have accidentally ended up in deleting my root directory while I blindly fired command while watching movie.
I fired following command
#rm -rf ~/<SPACE>*.out
instead of this command
#rm -rf ~/*.out
Things already done:
1) Created /root directory relogged to get some of basic settings of gnome and Desktop.
2) Things went well now when I login my desktop ,gnome environment and other things looks to be working well only prompt on my terminal has changed. I can fix it any ways.
Things I want to ask:
1) I haven't studied much about contents of /root directory to best of my knowledge is it like other user's home directory with some basic configuration files for mostly required applications. SO my question is have I lost any thing important system file or something?
2) If I have lost any important configuration or system data how can I recover it without reinstalling whole system? (My opinion about this is, It is quite possible but to do so, as far as I know capabilities of linux. But I still want comments from experts before I try any things on it because I don't want to backup my whole HDD and reinstall the whole stuff again for me and also my sister's stuff in MS.)
I've looked everywhere and haven't found someone with a similar problem or even a hint to how to fix it or what's even going on.I'm trying to mount the Sims 3 raw ISO so I can install the game with PlayOnLinux. Every program or method I've used to mount it seems to mount it successfully. My problem is, that when I go to open the mounted ISO image, the folder is empty and nothing comes up. Even when I go to rightclick > Properties,it displays the contents as nothing.

This is a Natty system. I ran update manager to update to the latest releases for Natty, and it crashed. I ran it again and it told me it could only do a partial upgrade, and that I should do apt-get install -f. I did that, but apt-get told me the system was locked by another program. Not to worry I thought, I'll just reboot. So I did that, and I think Update-Manager got a lot further through the process than I thought, because my system is borked. It'll boot into Gnome, but when booting up the Boot Screen no longer shows the pretty Ubuntu Logo, but rather a line of text that says "Ubuntu 11.04".
When it gets into Gnome the keyboard and mouse more or less don't work (although the keyboard based Fn+9 and Fn+10 brightness control still works) and there is no desktop background. After about 30 seconds something crashes but I can't click on it to find out what. Going into the recovery console doesn't help either. The latest Kernel (2.6.38-7) stops moving forwards after "Begin:Running /scripts/init-bottom...done". has occurred for the second time. Luckily I still have the previous kernel, which gets to the same spot and then tells me:
"init: udevtrigger main process (390) terminated with status 1" and then "init: udevtrigger post-stop process (394) terminated with status 1".
I then get the message
"The disc drive for / is not ready yet or not present. Continue to wait; or Press S to skip mounting or M for manual recovery". S goes back to "Begin:Running /scripts/init-bottom...done" a second time, M brings up the message:
"Root filesystem check failed. A maintenance shell will now be started"
and then it asks for the root password and gives me a terminal. Everything seems to be there, but apt-get and dpkg both can't do anything as the filesystem is read only.
I got 2 HDDs, I had created LVM by two of them. When I was trying to install quota it was saying it is better if you run fsck first message. When I tried to run fsck. It warned me that I could lose some of my data. So it happened. Actually it is worse: I can't boot my Fedora 11. When I try to run installer in rescue mode, it says no linux partition find. When I try to install (just to see partitions) it shows LVM volumes of hdds are ok but the partition which is / (root)partition seems in unknown format. How can I save my datas? Or can i restore my partitions, LVM?

I just installed FC10 and then used yumex to install the vsftpd FTP daemon package. I'm using the vsftpd.conf file that came with the distribution, and its almost identical to one I copied from my FC2 machine's working set-up. When I try to FTP in as a known system user I'm presented with my home directory /home/myusername/. The directory appears empty to the FTP program, but isn't in reality. I can't upload a file to the empty home directory. I can move up the directory hierarchy to /home/, but again that appears as an empty directory.
I don't think it's a vsftpd.conf file issue. I've tried everything I can there. Could it have something to do with permissions? I fiddled with those, but couldn't make an FTP directory listing work.

I have set up a cron job in linux server using the command 'wget -q -o wget_outputlog url'
But on every run, an empty file being created at root.
How to stop this.
I 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.

View 14 Replies View RelatedMy system system suffers from frequent kernel panics, which I think are due to gnome-shell with the nVidia driver. (I see no panic message and nothing is logged, but I've enabled magic SysRq and it makes no difference.) Twice this has occurred during yum-update's install stage, which is making me wonder. Uum-update then complained about an unfinished transaction, so I ran yum-complete-transaction as suggested. I've also tried yum-clean-all and rebuilding the RPM database, suggested in other threads, but I'm still seeing the following errors on yum-update:

I don't know where these 32-bit packages have come from this is an x86-64 system and the only x86-32 stuff I've intended to install is the Adobe flash plug-in. Also the later dupes are different 64-bit versions. I've tried "package-cleanup --cleandupes" as suggested in this thread: [URL]. It wants to remove the old versions, but also wants to remove packages that depend on them, including clutter, so I cancelled that. The first time round I was left with a barely usable system and had to reinstall, which I'd rather avoid, especially if this is going to be a regular occurrence. I'm not familiar with RPM (or kernel panics for that matter).

I had run F13 preupgrade as a test to see how it would go...(in case this is important) but had not rebooted yet...
Now when I boot I get the splash and the fedora droplet fills with white, though it gets progressively slower as it approaches the top. Eventually the infinite f appears but that's where it stays.
I have been able to boot to a live-usb stick w/F13. And after some shear panic, I discovered that the root partition is buried in lvm, in a 935 GB physical partition.
I have mounted the logical volume and dd if=/mnt/oldroot | gz > /ExternalBackupDrive/oldroot.gz
so that if I break things further there is a chance that I can get back to a working system.
Is it just that my bootloader doesn't know how to mount the lvm?
Where do I look for clues?
Is there a boot option that will let me follow the progress?
I have a machine which has only /opt with some decent amount of space where I can install a software. /opt belongs to root:root. The software I want to install cannot be installed as root user.
So lets say I create a directory called /opt/install1 and then chown -R install1 to belong to user1. And now I install the software under /opt/install1 with user as user1.
Is this a best practice violation? There could potentially be just /opt/install1 belong to user1 and in future everything else created under /opt belonging to root..
