Networking :: Viewing WEP Key Of Saved Access Point

Aug 11, 2010

About two years ago, my church set up a wireless access point. They gave it a WEP encryption, and wrote all the keys down on a piece of paper and taped it to the router, which was in full view, and reachable for anyone to get what they need and connect. I used it once, saved all the settings to the default network manager applet on my laptop (running Fedora Core 12), and put it back. Earlier this year, the front hall (where the router and paper with encryption keys was stored), was completely redone, and the router put up in the drop ceiling.

Mistake. Now the darn thing is sitting on top of Fiberglass insulation, and impossible to get to. There are people who need to connect, but since it's a church, and they don't really understand, they went and buried that router WITH all the encryption keys. So long story short, I need to get these people connected, but need to find the key... preferably without Hacking in. Is there a way, on the default "Network Manager" Applet, or in the terminal to VIEW saved keys?

Ubuntu Security :: Checking If Anyone Is Viewing Passwords Stored In FireFox?

Jun 16, 2010

As I am a paranoid bastard, I made a bash screencap-script for my Ubuntu-computer, so I can check if anyone uses my computer for things I don't want them to do (eg. checking if anyone is viewing passwords stored in FireFox, looking at private files, or other things I find disturbing). There might be other people than me that is paranoid and want to monitor what's going on on their computers while they are away or letting someone else use their computer when going to the bathroom.

This is a small script, I'd like to hear if there is any improvements that can be done, so I can learn more and become better at such scripting.

The script requires Imagick (sudo apt-get install imagemagick) and a folder in the ~-directory (/home/username) called ".screen" (hidden, as this makes it more difficult to "intruders" to find it and it looks more like a system-folder than a monitoring-folder).

The script:

Code:
#!/bin/bash
i=1;
j=`date`;
user=`whoami`;

[Code]....

Add this script to /usr/local/bin and then go to keyboard-shortcuts in GNOME and add a shortcut-key-combination of your own choice for the script. Call it whatever you'd like, and the command you want to run is simply "screen". To add a shortcut for stopping the script, you add another shortcut-key-combination to the command "killall screen".

This enables you to monitor activity on your computer while you're away, saving png-screenshots of your desktop every three seconds in the folder /home/username/.screen/date.

NOTE: I'm not taking any responsibility for what you do with this script. Remember that monitoring someone's activities is never the right way to handle anything. Also, it's illegal many places. Take care and use it only for educational and testing purposes.

Fedora Security :: Access To Vds Blockage?

Apr 2, 2010

I use putty and plink through ssh to support some process on my vd server (fedora-7) at godaddy. When login with plink frequently (ones per 10 seconds for just few minutes a day), the server blocks my access everywhere (sftp, http, control panel) for about 10 minutes and resumes then.Customer Support told me they do not have any blocker but I see that my ip is blocked for these 10 min. meanwhile I can access everything there from other address.

Fedora Security :: Any Way To Block IP Address Access?

Jul 27, 2011

I recently set up a web server at home, using a non-standard port, due to my ISP blocking 80. I just checked my log files, and I see a TON of entries indicating that a file was not found "proxy-1.php", "proxyheader.php", etc. I do not have these files, not intend to have them as part of my website. I did a whois looking by IP address for several of these, and they all seem to come from an ISP in China. Is there a way to BLOCK any IP address outside the US (that is somewhat simple to do?)

Fedora Security :: Prevent People From Unauthorized Access?

Mar 19, 2009

I'm doing a research to protect my pc from physical access. What I'm facing here is that my company created a program for fedora 8 and plans to sell the unit away. We created a function where you can configure the program using any web browser from a network so we do not want anybody to have access to the fedora except for out personnel.

Based on my research, I've found [URL] this guide to protect people from accessing grub and single user. I am currently researching on preventing others to clone the harddisk. I would like to know if there are any other methods to prevent people from unauthorized access to fedora.

Fedora Security :: Root Access For Winows Partitions?

Oct 6, 2009

I'm currently running a dual boot (VistaFedora 11) system. I've noticed that the first time I access files on the Windows partition (via Nautilus GUI) I'm prompted for root access. However, on subsequent attempts to access the Windows partition I am NOT prompted for root access (even after I close/re-open Nautilus). My concern is that I'm leaving my root access "open".

Fedora Security :: Iptables Masquerade, Can Ping But No Http Access?

Dec 13, 2009

I've got two routers, 10.0.0.0/23 and 192.168.2.0/24, which are joined by a Linux box with interfaces eth0 (10.0.0.2) and ra0 (192.168.2.2). I've got masquerading for ra0, and a route to 192.168.2.0/24 on 10.0.0.0's router. I CAN ping hosts on 192.168.2.0 from 10.0.0.0 just fine, but I CANNOT access web pages.Strangely, If I enable masquerading on eth0, and add a route to 192.168.2.0s router to 10.0.0.0, I can ping AND access web pages from 192.168.2.0Here is my current iptables

Code:
*filter

Fedora Security :: Print - SELinux Is Preventing Access To Files With The Default Label - Default_t

Mar 13, 2009

I went to print something and I get this message: Summary: SELinux is preventing access to files with the default label, default_t.

Detailed Description: SELinux permission checks on files labeled default_t are being denied. These files/directories have the default label on them. This can indicate a labeling problem, especially if the files being referred to are not top level directories. Any files/directories under standard system directories, /usr, /var. /dev, /tmp, ..., should not be labeled with the default label. The default label is for files/directories which do not have a label on a parent directory. So if you create a new directory in / you might legitimately get this label.

Fedora :: No Sound With FF When Viewing Flash?

Jul 27, 2009

Installed Fedora 10 a few months ago. Was using pulseaudio and when viewing flash in firefox I was getting sound. I was experiencing too many problems with pulseaudio and other apps, so I uninstalled pulseaudio and now I'm using alsa exclusively. However, since doing so I no longer have sound when viewing flash in firefox. Sound when playing movies and/or listening to music is totally fine. I tried removing firefox and flash-plugin and installing them again but to no avail. I'm on FF 3.0.12 and flash-plugin 10.0.22.87-release.

Fedora :: Difficulties In Viewing The Drives In 13?

Oct 11, 2010

Recently I have installed Fedora 13 both in my home and office computers only replacing the previous Fedora 11. I didn't edited the partition table in either cases. At office computer I only have one hard disk with C: and D: partition in NTFS and the linux partition. In Fedora the C: and D: are shown now as /media/disk and /media/disk-1. How to see these drives as /C and /D? In home computer I have two 500GB hard disks. sda1 is FAT formatted and all of its drives are shown in either platforms nicely. sdb1, the other 500GB HD has two drives (N: and P each of 250GB and both NTFS formatted, is shown as /media/New Volume in Fedora 13, however opening it shows only the content of N: drive. Can't do anything using Disk Utility of Fedora 13.

Red Hat / Fedora :: PHP Files Want To Download Instead Of Viewing Them?

Mar 22, 2010

when I try to view php files on my linux box, they want to download instead of viewing them. I configured apache for php as the manual said but for some reason it doesn't want to parse the php. the http.conf file may need to be changed, that the line "AddModule mod_php4.c" was missing in the conf, however the AddModule and ClearModuleList directives no longer exist in the newer versions of Apache. These directives were used to ensure that modules could be enabled in the correct order. The new Apache 2.0 API allows modules to explicitly specify their ordering, eliminating the need for these directives.

Fedora :: Viewing Source Code For Package?

Mar 3, 2011

I was a die hard Ubuntu user for the last 2 years and decided to use something more advanced or different. My question (after searching the crap out of Google) is how can I view the source code of Fedora? I have found many sites explaining this but it is not written in terms that are easy for me to understand. I haven't been programming for years and using advanced features in Linux so most of these sites are not explaining out and most are explaining how to build and add on to the kernel.

Fedora :: Internet Browsing/page Viewing Is Very Slow

Jun 15, 2010

I have a 2.6 P4 with HT and 1GB of PC3200. i'm using an RaLink 2760 based wifi card. i compiled the driver from source, don't think it matters because i get this problem on ethernet as well. video is RV280 (radeon 9200). i have 3D accelleration supposively and get 570fps steady with glxgears. i'm in F11 updated as far as yum will take me.

When browsing websites, usually forums but even things like ....., the computer acts like it's being bogged down by something. i scroll down a page and it takes a few seconds for the screen to catch up. i understand i'm not running the most up to date hardware but i don't think this machine should have any problems with web browsing.

Here's an lsmod

Fedora :: Viewing Pdf Files In 12 - Error: Couldn't Read Xref Table

Apr 25, 2010

I switched back to Fedora after a long time and wow a lot of things have changed! Fedora 12 is looking amazing and the best part is I could install it on my USB so easily. And then I found I couldnt open any PDF files on Fedora - I tried installing AdobeReader, xpdf and openoffice. All of them are just throwing some file format errors.... <I cant push a screenshot now since i removed the packages>

Initally i thought it might be some version conflict but it turned out I couldnt open any pdf's including docs from 5 years back to docs with embedded media content. I know I havent put any info here. I am looking for a little info on what is needed to get Acrobat/Xpdf working in Fedora 12... And I couldn't get any errors logged so I'd like a little help there if I need to share some debug messages...

that gave these messages [root@localhost Presentations]# evince module-development.mgp.pdf

Security :: URL (Not URI) In Apache Access Log?

Mar 6, 2010

I happened to be looking at my Apache-2.2.8 log on an Ubuntu LTS 8.04.4 system, and noticed a few lines like this:
Code:
61.160.212.242 - - [06/Mar/2010:07:04:41 -0800] "GET http://218.30.115.246/ HTTP/1.1" 200 295 "-" "-"
61.160.212.242 - - [06/Mar/2010:07:05:29 -0800] "GET http://218.30.115.246/ HTTP/1.1" 200 295 "-" "-"
xxx.xxx.xxx.xxx - - [06/Mar/2010:07:56:15 -0800] "GET http://218.30.115.246/ HTTP/1.1" 400 290 "-" "-"

(The third line is me telnetting to the server and trying to issue the same request. Note that I got a 400 error response, while the guy coming from 61.160.212.242 got 200s. Also, if you just open the http://218.30.114.246/ URL, you get back "hello" (nothing else, just 5 characters). I'm presently putting together a bootable CD with chkrootkit to run on the machine. (I found a thread that mentioned in passing that this was related to PHP, which I have running on that Apache server, but my Google-fu isn't strong enough to track down the original thread.) (After checking with chkrootkit: nothing unusual found.)

Ubuntu Security :: Disable The SSH Key Access?

Jun 15, 2010

I currently have a user on my Ubuntu server that I want to block completely from login. I know right now they login with SSH keys so they don't need to enter their SSH password. Can anyone tell me how to remove the SSH key login for their username and root user which I believe they use too and block SSH access alltogether.I will then just change the root SSH password.I'm terrified they will do some harm so I need them blocked out ASAP.

Ubuntu Security :: Which App Is Trying To Access My Keychain

Jun 14, 2011

I am used to, on starting Ubuntu on my Netbook, being prompted with a password challenge to open my Keychain required to authenticate against the WPA enabled WiFi network.

Now, Ive recently installed Ubuntu on a desktop PC, along with some dev tools (Code::Blocks etc.) but it gives me a keychain access challenge about 4 times on startup. I can't seem to figure out which app is trying to (get my permission to) access my keychain, and for what Purpose.

(By contrast: on my Mac, when an application tries to open the keychain, the application, its certificate, and the search data of the matching key that will be accessed are all displayed making it much easier to determine what app is being naughty) How do I do simular diagnostics with Natty?

When I cancel these requests, nothing "breaks".
