Ubuntu :: Log Are Written To Every 2 Seconds, Denial Of Service Attempt?

Nov 12, 2010

I am posting a thread here for more help. I posted a thread about this problem [URL]..History: This was a clean install of 10.04.1-64b see attachments for lshw and lspci output. An updated bios was needed to be able to turn on the wireless chip, that was done following [URL].. see post #8 there is some issue, the manufacture removed the updated bios from the website.

If I was to guess it has something to do with driver rtl819xSE. I also noticed some 'static' at the lastmountpoints the usb drives. I think the problem here is that this would cause an idle drive never to park and sleep maybe shorted drive life, the logs would become over bloated with this spam, also eat up a battery on a laptop.

Security :: How Does Mktemp Prevent Denial Of Service Attack

Apr 22, 2010

This is an excerpt from the Linux man page for mktemp command: "mktemp is provided to allow shell scripts to safely use temporary files. Traditionally, many shell scripts take the name of the program with the PID as a suffix and use that as a temporary filename. This kind of naming scheme is predictable and the race condition. It creates is easy for an attacker to win. A safer, though still inferior approach is to make a temporary directory using the same naming scheme. While this does allow one to guarantee that a temporary file will not be subverted, it still allows a simple denial of service attack. For these reasons it is suggested that mktemp be used instead."

- How can a denial-of-service attack be carried out if a directory name is known?
- Why is it important to use mktemp to generate a sufficiently random file/directory name for temporary files?

Red Hat :: ACV Denial After Update?

May 16, 2010

I ran an update of my centOS (5.2) machine today. After reboot, I tried an upload, but I got

Quote:
553 Could not create file On the server (where I upload to) I get an AVC denial.Short list of what I have here:

- Centos 5.2
- a pass & login for a user, chroot to his folder
- the group and owner are set to the user in the user's folder, there are write permissions
- symlink to a folder in the /var/www/html folder
- it worked before, I possibly lost a seLinux setting somewhere.

Fedora Networking :: Ethernet Connection Sabotaged By SELinux - AVC Denial ?

May 26, 2009

I installed Fedora to a desktop with a hardwire ethernet connection to my router. When I ran the live CD it connected fine. When I boot now I have no connection, and when I try to connect I get this "AVC Denial" message and some mumbojumbo about SELinux is preventing nm-dhcp-client to read libdbus-glib blah blah blah. The troubleshooter app is no help to me at all. This is extremely frustrating. A couple of weeks ago I did an install to this same computer and had no problem at all. The only difference is that this time I wiped all of my old distros from the HD, and made separate /, /var, /boot, /tmp, and /usr partitions (in addition to the old /home partition which I kept.) I don't know how that could be causing this problem, but it's the only thing different about this install. Should I just go back to putting everything but /home on one partition?

Security :: CentOS 5 - SELinux Denial Of Wicd / Wpa_supplicant - Get Wireless To Work Properly Using Default NetworkManager

May 11, 2010

I am trying to use CentOS 5.4 to set up a secure laptop, largely because of it's SELinux functionality. Unfortunately I couldn't get wireless to work properly using the default NetworkManager so I installed wicd. Initially it buggered up my whole installation but after relabelling files using SEL I can now use my system again. but.. I can't use it with SELinux enabled, as it denies the required accesses for wicd to work. I also get similar SELinux denials for wpa_supplicant. A couple of snippets from /var/log/audit/audit.log -

Ubuntu :: Nothing Written In Fstab ?

Jan 31, 2011

I've been having a lot of problems solving my HDD mounting problems and renaming. It finally worked, but I had to delete everything from fstab. As crazy as it sounds, it worked, when I turn my computer on, they automatically mount. They are all working fine. I will attach screen shots too. As you can see my fstab is blank, I was just wondering, is this a problem? Or is it totally normal?

Ubuntu :: Running Aplicattions Written In Pearl

Dec 31, 2010

I'm trying to edit mobi files. To do so, I looked for a mobi2html program, which I found here:URL...I followed all the instructions mentioned in the READ_ME file that comes with the zipped source. I strongly believe, as no error messages appeared during the installation, everything went according to plan.My question is simple: having completed all the installation procedures, what should I do next? My general procedure is to look up for the new program name in the "applications" tab, but I know that won't always do the trick.

General :: /var/log/messages Is Not Being Written To?

Nov 1, 2010

I was attempting to get crontab to kick off a daily job, but the job wont start. I opened /var/log/messages and noticed all the logs were from 6 months ago. I cleared the log and then did a tail -f so I could watch it for activity. I then hit my box with anunsuccessful log in attempt. Nothing happened to the log. The uptime of my box is 22 days and the logs that were in it before I cleared it were from months ago.Is there a daemon I can check or another file I can mod to get logs writing again?

Ubuntu :: Create A Directory That Can Be Written To By Multiple Users

Feb 6, 2010

I have a small ubuntu server setup and I would like to create a directory that can be written to by a select number of users. I have a backup directory setup and I want to enable my account as well as three others to be able to read/write to that directory. So far I haven't had any luck.

The owner of the backups folder, a directory on a separate disk mounted under /srv/storage, was owned by root and under the root group. I added the group backups and then changed the backups directory group to backups. I then used chown to change the backups directory to 775 to enable group members to write to it. I then tried to touch a file in the backups folder but no such luck. I did notice that when I run groups, my user account isn't shown as belonging to backups but is shown under the /etc/group file. I even made sure the GID of backups is in fact below 1000.

Anyone have an idea on how to create a shared directory that everyone can create, modify and delete any file? I believe my problem is related to the fact that root is the owner of the backups directory.

Ubuntu :: Error While Installing Software Written In Python

Jul 1, 2010

For example, I want to install a texteditor called Editra, i done it like the following

First, I install the Editra
sudo apt-get install Editra - success ,its version is 0.5.30

Second, I run it in Terminal
Editra - it can work,but with the error infos "(python:1682): Gtk-CRITICAL **: gtk_widget_add_accelerator: assertion `GTK_IS_WIDGET (widget)' failed"

Third, I used command line "dpkg -L Editra", and found that the Editra is installed under /usr/share/pyshared/Editra,so i created the .desktop like this
sudo gedit /usr/share/applications/Editra.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Editra
Comment=the Best TextEditor
Exec=/usr/share/pyshared/Editra
Icon=/usr/share/pyshared/Editra/pixmaps/editra.png
Terminal=false
Type=Application
Catergories=Development

It showed, and I clicked it for running, but it told me error infos
Could not launch 'Editra'
Failed to execute child process "/usr/share/pyshared/Editra" (Permission denied)
Not just Editra, so many software that written in python have the same question, such as tortoisehg...

Code: gcc -o hello.cgi hello.c Also grand a+x to the file and enable *.pl and *.cgi for cgi-script at apache2.conf The server reminds me 'Internal Server error' The weird thing is that I have a perl cgi in the same place with same privilege, which works perfect...

Fedora :: Verifying Files Written To A DVD?

Dec 26, 2009

I've been having trouble writing to DVDs on one computer, and I am trying to figure out whetgher the problem is hardware or software related, or, perhaps, both. The brasero CD/DVD writer puts the md5 checksums of each of the original files in a hidden file on the DVD. I think it then calculates the sums of the copies and compares, but the last time I did it, it told me it had permission problems with the drive, and that failed. When I put the DVD in, udev finds it and mounts it in /media with me as its owner. Apparently, brasero mounted it some other way, and presumably that caused the problem.

Secondly, after I brought it up again, I went into the /media mount point and did md5sum on the files there. One of them a gzipped tar file, produced and input/output error. Yet if I use cmp to compare that file with the original it finds no difficulty. So what is going on? Finally, I have tried to write shell scripts which use cmp to compare the original files with the copies. The general form is

cd XXXX
find $* >> /tmp/X
for i in `cat /tmp/X`
do
cmp $i YYYY/$i
done

where XXX is the mount point in /media and YYY is the original directory containing the relevant files. This works fine except that if the file names have spaces in them, the shell script treats each word as a new file name. So I need some way to arrange things so that `cat /tmp/X` returns the complete file name. Nothing I've tried works.
