Security :: Tmp Filling Up With Root-tmp Diretories?
Apr 26, 2010My /tmp directory is being filled up with root-tmp.####. I suspect they are being created by bastille-tmpdir-defense.sh, but they do not seem to get removed.

Debian :: Root Partition Filling Up
Dec 22, 2015I'm booting to Kali 2.0 live from USB and wanted to add persistence, but I can't get OpenVAS setup. The setup script runs and eventually fails due to no more disk space. Here's my df -h output:
Here's gparted:
When the setup runs it fills up root (/) which is only 872mb. This is a 16gb USB so I'm wondering if there's a way to allocate some of the 11gb of unallocated space to root? I couldn't tell how to do this with gparted, would I need to build a custom Kali iso or something with different partitioning?
Ubuntu Servers :: Max Limit On Filling Up A Non-root Partition?
May 18, 2011I have a number of servers I manage, and one of them is archiving old data that is never modified on a separate partition. This partition is at 100% capacity. A friend of mine says this is an unsafe way to keep this partition, even tho I don't plan to add any more data to it or change anything within. I know I can archive the data to dvd, but I'd like to keep the data online for my users.
What are your opinions on this? Can I keep this archive partition at 100% capacity? Or do I risk some sort of data corruption? Should I mount this partition as read-only to help prevent any corruption?
Ubuntu Servers :: Root Mailbox Filling With Cron Messages?
Feb 3, 2010I'm getting the following messages sent to my root account mailbox. It appears to be reporting an issue finding ntpdate, however when running the following command:

It shows as installed and any ntpdate commands work with no issues, so I have no idea why this is getting regularly reported?

General :: Cannot Open File In RW Mode - Filling Root File System With Log Files
Nov 3, 2010I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.
View 6 Replies View RelatedGeneral :: Deleting Another User's Diretories From Own?
Apr 12, 2010I am a non-root user, and have made a directory into which other users in my group can write. The directory is setgid, so files and directories within it have the same group.I can delete files placed into this directory, but if a user creates a subdirectory with files in it, I can't seem to delete those. Is there something special I can do (other than, say, bothering the user in question or the sysadmin about it) to get rid of this subdirectory?
EDIT: Inevitably, of course, someone asks "why?"The shared folder in question is a mercurial repository. We can't use a shared-account ssh-key-based server for this like mercurial-server, and we can't just host it externally for various reasons. But that part works fine.We use Redmine for project management, but it does not yet read the repo index for file contents - it reads the working directory. So the working directory must be kept up-to-datecrontab has been disabled by the sysadmin, so that's out. So I naïvely put a changeset hook in the shared repo that performed an "hg update". This seemed to work fine initially, until, of course, someone pushed a commit with a new directory. While I had vague thoughts of trying to make a setuid script for the hook, I'll probably just consider safer avenues.
Ubuntu Security :: Giving Root Permission To An Application But Without Running It As Root?
Jan 20, 2011want to run VirtualBox with root permissions. 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.

View 9 Replies View RelatedUbuntu :: Disk Filling Up - Disparity Between Df And Du?
Feb 19, 2011For a while my root partition has been filling up for no apparent reason. I I have been deleting things to find out it fills up again in a mater of days. To make it more 'interesting', there is a disparity between what I get from df and what the du command is telling me. After dismounting the other file systems and turning off applications, this is what i get:
output of df -ha
Code:
Filesystem Size Used Avail Use% Mounted on
/dev/sdf5 69G 66G 54M 100% /
proc 0 0 0 - /proc
none 0 0 0 - /sys
[code]....
du claims that I'm using 29G on that partition, which sounds about right (this is my OS and basic /home partition, everything else is elsewhere). df on the other hand is telling me here that out of 69G, 64G are in use with only 54M left.
General :: .snapshot Filling The Nfs Disk?
Jul 19, 2010I have a lot of data on a nfs store external to an Ubuntu machine. I've had problems with the storage becoming full and have spent a very long time deleting files to get absolutely nowhere! Over 25GB of deletions on the 80GB disk has only cleared 1.5GB of space...
You can see below the hidden .snapshot directory, the disk usage for the nfs-store is coming out at 97GB when the disk is only 80GB in size, and the two directories I want on the disk are about 22GB in size.The .snapshot directory appears to have been made on Friday, I'd like to know if I can:
1) find out what command ran to create/update it
2) re-run the command to update the directory or remove the directory
Code:
ideasadmin@ideasadmin-desktop:/nfs-store$ ls -la

OpenSUSE :: X11 Directory Replicating In /usr/bin, Filling Disk?
Dec 5, 2010Noticed that one of my partitions on openSuse 11.1, mounted as /usr, filled up suddenly with over 20 GB of something. Tracked it down to /usr/bin, in which the X11 directory contains 2353 items and another X11 directory, recursively at least 11 times that I've expanded without reaching the last X11 directory. The newest files in each directory are dated 11/24/10.
Any idea of what's happening? How to stop it before it fills the disk?

Ubuntu Servers :: Cron Is Filling Up Logs?
Sep 1, 2011I am using my ubuntu server as my home router.Everything is working as expected with one exception.y DSL modem is a POS and every now and again it looses connection to the router. Sometimes it needs to be reset and sometimes it does not.Either way, when this happens my ubuntu server needs to reacquire an IP from my ISP. If it screws up when I'm at home it's no big deal, but if it happens when I'm not around my housemates have taken to hitting the reset switch on the server. I'm not a big fan of this so I wrote a script to ping my ISP's gateway. If it's unavailable it bounces the eth0 interface and tries to get an IP. I am running this script every couple of minutes in a cron job. Now I'm getting syslog entries like

Server :: BIND Messages Filling Up SysLog?
Dec 9, 2009I have the following BIND messages filling up my SysLog that I'm hoping someone can explain to me:

I would expect this behavior if "domain.com and anotherdomain.com" wasn't a domain that I hosted. But this is a valid domain that this server should be answering for. In my named.conf I do have the
Quote:

option on every zone. This is my slave server and I have the primary shut off so I can test this slave server. FYI: So far queriers still seem to be working. The pages for the sites are still coming up via the internet.
Fedora Security :: SSH Only As Root?
Aug 19, 2009I have a fedora 10 server to which I can ssh as the root user using RSA.
However for any user other than root a password is always requested.
I have made changes to PAM and check the rights to all the files and read pages upon pages. I can mess it up completely so no one can login but cant get it so that anyone other than root can use a public key.
Another interesting and may be related item is that when any user logs in, with a password, via ssh then they get the error:
Could not chdir to home directory /home/xxxx: Permission denied
But they can cd to their home directory and have no problems.
I am thinking that this may be to do with the mount. The home directory is on a HDD but the system dive is an SSD.
I have gone over everything so many times I am now lost, I must be overlooking something so simple and obvious its just not coming to mind.
Security :: Can't Su To Root, After Chmod -s /bin/su
Mar 7, 2011When I try to issue "su -", I get "su: Authentication failure", and I'm 100% sure password I enter is ok.
I think it started to happen after I issued
chmod +s /usr/bin/screen
chmod 755 /usr/bin/screen
which I believe is unrelated to this problem, and,
chmod -s /bin/su (-s by mistake)
chmod 755 /bin/su
which most probably made the whole mess...
this is not the part of the problem I believe but here's some background why I did that... when trying to make possible for screen sessions to be started automatically on boot under non-root account, I entered something like "su - username -c "/usr/bin/screen -dmS screenname ./executable-file"" in bootmisc.sh, but I was getting "must run suid root for multiuser support", so I tried to fix it, and now I can't login to root account no way.
