General :: Only Allowing A Limited Number Of Directories?
May 14, 2011
I have a drive NTFS formatted drive mounted in Debian and a script set to make directories via a linux script and cron job. This was running flawlessly till recently, when I started getting 'mkdir: cannot create directory 'dirname': Operation not supported'.I have been unable to find any help with this issue online. I assume it is a NTFS mount issue. I know it isn't about file size, as the drive it 1TB.Here is my fstab for reference:Code:/dev/sdb1 /mnt/backupLocation ntfs-3g rw 0 0Do you know what the issue is here? Like I said, up until recently I have been able to create seeming unlimited directories here, but it now stops after about 7 - 10 directories have been created?

I'm looking for a way to produce a list of all the directories in the current working directory sorted by the total number of files that are contained with them.
Initially I though that Nautilus could be used for this, but then I realised it doesn't count files in the sub directories.
The best I've got for a command line solution so far is this
Code:
The use case for this is a situation where a user has a quota applied to their home directory which limits the number of files they are allowed to have and they have exceeded that limit.

I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
function investigate
{
path=$1
for file in `ls $1`
#for file in *

I recently used up all my free inodes on my server. I had a bunch of mail messages that were sitting there using up a bunch, so I cleared the postfix queue. That gave me some room. What I'd like to do, is get a listing of the directories using the most inodes (or containing the most number of files), so that I can find the other culprits.Basically I want the output of "df -i" but to be able to do it recursively on a specific directory.

I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?

As you may well be aware the resolv.conf search appears to be limited to 6 domains. I need 7 One thing I noticed is that if you run nslookup on a short name that is in the 7th search it does work but ssh does not. I'm guessing that nslookup is actually reading the whole file and isn't limited.

I have Fedora 10 set up as a server. Occasionally it will stop allowing connections, such as ssh, http, and samba. This continues until someone hits a key on the keyboard, and then it seems to come back to life and accept connections. At this point, the date and time will be wrong. Judging from monit messages that inform me when it stops allowing connections, I think the time freezes at whatever time it is when it stops allowing said connections.
Power Management has it set for the computer to never turn off. Sleep mode is also disabled in the BIOS.
I thought it was possibly the CMOS battery, but that has been replaced and the issue persists.
Someone previously thought it might have been Network Manager, but that is disabled due to issues it has with a static IP.

I just got a new SSD, and I'm looking for advice on how best to incorporate it into my existing LVM setup. I have the following logical volumes (mounted at the obvious places):
[Code]...
I've got 108.26g in the physical volumes associated with the new SSD. I'm going to use pvmove to migrate some of these LVs to the SSD. The question is, which LVs to move?
The machine in question is basically a home workstation. I do some light development (source code lives in home), run some very low-load server processes (apache, etc.), and do a bit of image and video editing from time to time. I run Gentoo on x86 if that makes a difference.

Is it possible to have more than one password simultaneously attached to a login account in Linux?I'd like to be able to add a temporarily-authorized user to an account on my web server, but don't want to have to change the login afterwards.Even cooler would be if this could be done with a timer of some kind so the temporary password would auto-die after, say, 24 hours.

In order for me to get started with Linux, I downloaded & installed Virtualbox (V3.2.10) on my WinXP machine, and downloaded the Puppy Linux image from as per[URL].. When I start up the VM, I get a GRUB menu allowing me to boot
Quote:
Linux (on /dev/hda1)
Install GRUB to floppy disk (on /dev/fd0)
Install GRUB to Linux partition (on /dev/hda1)
I tried the first option, which results in Quote:
Booting 'Linux (on /dev/hda1)'
root (hd0, 0)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinuz root=/dev/hda1 ro vga=normal

Each day I need to copy N files from a source location to a mirror at a specific time (where N is very large). Let's say I tell multiple CPUs to each run an rsync simultaneously on a subset of the files (network and disk bandwidth are not an issue). Ideally each CPU would be responsible for a disjoint subset of the N files, but in practice this is sometimes hard to guarantee. (Some of the source files might be "claimed" by more than one CPU.) As a result, sometimes rsync I and rsync J will both try to copy file F at the same time.
Using rsync -avz --delete --temp-dir=/tmp remote:/path/to/source/ /path/to/dest/, let's say rsyncs I and J both see this situation to start:
[Code]...
Now rsync J finishes copying but generates an error when it tries to move its version of FileB to /path/to/dest/ because there's already another FileB there that it didn't see when it started.
Does one of rsync's many options somehow handle this situation? Ideally I'd like an option that tells rsync, "Believe in yourself. You can do no wrong. Feel free to overwrite anything your little heart desires." so that it wouldn't complain about the FileB that has suddenly appeared mid-execution

Most of us know the basic security practices on Windows:
Use a limited account
Set a password
Disable unused services
Uninstall bloatware
Antivirus / Antimalware
etc.
I haven't ran linux as my main desktop computer before, so I don't know how to properly secure it. I have heard linux is supposed to be more secure than Windows, but I know that the default settings of anything are rarely secure. What are some things I should do as a new Linux user to secure my desktop system from attack?

I have run into a problem with my desktop using roughly 50% RAM (w/o buffers or cache) while running a limited set of applications (fbterm, tmux, weechat, ncmpc, rtorrent) on the command line. This usage only increases roughly 5-10% when starting X (an addition of xcompmgr, awesome wm, zim, parcellite, 2x conky (one replacing root-tails functionality), plus firefox and other apps that may or may not be running from time to time). (h)top is reporting programs only using roughly .1-.2% per proccess and roughly 100 processes (current look at top shows 120 processes, only 32 of which are registering any usage over 0.0%) The RAM usage when in the console (which I will add is about 150MB after boot) is totally unreasonable and I need some direction on trying to find out what is using all of this RAM.
System:
Distro: Arch Linux
RAM: 2G
CPU: AMD 64 x2 4800+
HDD: 3x WD Black 750G (RAID 5 on partition 2 (swap) and 3 (root), RAID 1 on partition 1 (boot). LVM over root partition)
GPU: Nvidia 8400 GS

I'm trying to make a shell script that will list the 50 newest files in a directory with several subdirectories in. I've been trying with the find-command with no luck and now I've figured I should probably use ls. The problem is when I do "ls -lRt | head -50" it will do 1 directory at the time. It will not first make the full list and then sort it. This will display all items in first directory, sorted, then the newest directory will be sorted and displayed. So I figured I have to sort the whole process of ls before I limit the head. So this is where I am at now: ls -lRt | sort <something clever here> | head -50
Only doing a "|sort|" will sort it by name if I understand it right and I don't know how to solve it. Here's also my first attempt if that is of any interrest or help, this was limited by the change status time of files (so some lists got very large). These lists dit not get sorted by time and I could not find any way to do so.find $ftpDir -ctime $time -type f -print > $ftpFileLsAny help on this would be appreciated since I'm sort of stuck now. After reading manuals for all the options I can think of and still there's just a big blur in my head..

I've hit a wall here; I'm attempting to find some way by which to view files and cd into directories on a device mounted read-only. So I need the permissions to read, write, execute (and the same with directories), but chmodding is out of the question because I don't want to alter the drive one iota.
I guess what I could do--what I was thinking of initially--was to dupe the whole drive and then mess with permissions. This wouldn't affect the original (actually I'm working on a duplicate of the original, but I'm treating it as if it were the original) but I was hoping for something that would maintain data integrity. This is a forensic application and not altering the data is very important.

I need to process billions of small files using bash shell commands with limited memory size (256MB). If any of those files contain certain "keywords", the file will be removed. I tried with command:
find . -type f -exec grep -i -l -H "keyword" '{}' + | xargs rm -rf
where all files are located within the current directory. But the command above failed in "out of memory".

With Azureus/Vuze, can we set an upload/download rate limit depending on the time of day?
If not, do you know a torrent client allowing this? Client must be available on Linux.
I learned that you can install plugins for Azureus/Vuze. There is one about scheduling. I've tried to install it but I got a NullPointerException.
