Once I deleted a log file and recreated it. After I did so the new log file was not being written to. I was told that it is because the file I deleted is still running and being used in memory. What is the memory portion called(such as user space) that the filesystem run in?
View 5 RepliesI am attempting to recover a deleted text file. I used dd to make an image of the sectors on the hard drive which contained the data. Now, since I am not getting good results with foremost, and know all of the lines I'm looking for contain "Style", I want to grep the .img, but when I do it runs out of memory. I have tried the grep option -D, set to skip, and tried adding a 3GB swap to account for the 2.7G image. It still "exhausts" it's memory, and it seems to happen really quick now.this is the output of ulimit -a
Code:
root: $ ulimit -a
core file size (blocks, -c) 0

Just wiped Windows on a Dell Inspiron 8000 and installed Ubuntu. Most things going well but ran GIMP today and noticed the dissolve very slow. Think I might need more memory? I typed $ free -m and got this:
total used free shared buffers cached
Mem: 497 483 14 0 15 215
-/+ buffers/cache: 251 245
Swap: 839 43 796
I take this to mean I have 500MB of memory but most of it is used up on something? Does this explain why opening new windows incurs a lag of a few seconds and my GIMP slideshow runs very slowly? I was a pretty good Windows user but know very little about Linux.
I'm trying to get away from FAT and FAT32 for my memory sticks. Is ext2 really a suitable option for usb memory sticks?
I don't want to use ext4 because of journaling, as it's simply not required for usb sticks.
I have a launcher for Quake that essentially runs a shell scripts that runs quakespasm with certain options. Is there a way to add it to AWN?
View 6 Replies View RelatedI 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'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.

View 4 Replies View RelatedI have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.
View 1 Replies View RelatedI 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?
This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.

View 7 Replies View RelatedI installed Ubuntu Hardy Heron about six months ago, and it has gradually slowed down, and CPU utilization has crept up to the 50-60% range. The DEV folder contains a large number of similar files - TTY0 through TTYZF or PTYA0 through PTYZF. I suspect that something is not configured right, but, I don't know where to look.

The problem is I need the php program to send member email confirmation which contains a confirm link. Run every min may still make the member wait. So I like to make it to run every 20 or 30 secs.
I don't want to put the code to send email on my sign up page as that's no good.
But I don't want to put a sleep 30 sec on my php script and going on loop. If it failed in the middle then it may wait abit to start.
What can be done to achieve my goal and what's the best way?
Making a php script to run as a daemon process? Is that possible and okay?
I'm using vim 7.2.330 on 64 bit ubuntu 10.04, sometime in the last week every time I reopen a file it places the cursor at the top of the file. I can see in ~/.viminfo where it's saving the last position used, but it doesn't seem to be honoring it.

View 1 Replies View RelatedSo here's the problem. We've got the /etc/sudoers file set up so that users can run commands from /bin like "cat" or "mkdir" without entering a password. The problem is that the "su" command is also in /bin, so if they enter "sudo su", it gives them root access without a password. Here's the /etc/sudoers file:
Defaults targetpw
%users ALL=(ALL) ALL
root ALL=(ALL) ALL
support ALL=(ALL) NOPASSWD: /sbin/, /bin/, /opt/, /etc/init.d/, /elo/
support ALL=(ALL) NOPASSWD: /usr/bin/mysql
Is there a way I can deny /bin/su while still allowing the rest of the /bin commands?
I found this Is the Success of Google's Android a Threat to Free Software? (thanks to linuxtoday.com) and in the end it says
Quote:
Worse, if efforts to enable Android apps to run on distros like Ubuntu succeed, then we may see closed-source software being used on the free software stack there, too. Ironically, Android's success could harm not just open source's chances in the world of mobile phones, but even on the desktop.
I don't see how this is a threat too Linux but that's not why I'm here. I've never understood why some say that Linux is too fragmented for developing games and other applications. I mean Savage 2 comes in one Linux(.bin file) version and it runs on most of the distributions. What is the difference between all the package formats (like .rpm and .dpkg). Why won't a application run on all systems with the Linux kernel on it? Can someone with more computer and Linux knowledge please explain this to me?
I have been doing this for quite sometime now, yet lately I wonder if this is what everybody does...I have a task that will run for hours. In order to not to interrupt that task when I logoff for the day, I issued the command:

Is this what everybody else does?

I would like to have this script running even when I am not logged in. At the moment it runs but only when I am logged in. I logged as denis and in terminal (su root) and edited crontab as shown below, what do I need to change or setup to have this script run when no-one is logged in the computer.

I just installed Arch (x86_64). I am trying to setup Xorg. I have not installed a DE or WM yet, I just want to make sure Xorg is 100% first.
I had to edit the xorg.conf myself to direct it to my Intel graphics driver, but now it seems to work perfectly.
Except after exiting X, my terminal reads:
Code:
xinit: connection to X server lost
waiting for X server to shut down xterm: fatal IO error 11 (Resource temporarily unavailable) or KillClient on X server ":0"
XIO: fatal IO error 4 (Interrupted system call) on X server ":0"
after 1011 requests (1011 known processed) with 3 events remaining.
xterm: fatal IO error 104 (Connection reset by peer) or KillClient on X server ":0"
I'm pretty new to Linux and have no idea what this means! But I'm assuming it's not normal, because it says 'error'.
I have a box that is Rec Hat Linux 5.4 with Apache server 2.2.3 . I'm told there are multiple vulnerabilities in Apache httpd, that version 2.2.16 or later is better. However, I did a package update this week and 2.2.3 is where I sit. Is there a newer version that will run or a patch for 2.2.3? Upgrading Red Hat is not an option.
