Jul 12, 2009I'm not necessarily gonna do this, but I have to know. Is there a way to make the system not complain about every single freaking password you try to use? Make it so that any regular user could make "hello" their password without complaint? Like I said, I won't necessarily do it, but I have to know if it can be done.I did some searching and found the su -c "passwd username" trick, which is working for right now (I have root access but a user account I made for a friend doesn't)... it's just irritating when it won't even let him use something like "snuh123" because it seems to think it's based on a (reversed) dictionary word. Any use of a dictionary word, even with other chars, fails

Jun 22, 2011The problem is that yum is refusing to install gcc on a new SL6 install. As far as I can make out, a security update that I applied prior to my attempt to install gcc has caused problems. I did a new SL6 install (x86_86) a couple of weeks ago. This was a minimal installation, and I didn't install any dev tools, as I intended to install them later from yum. Since then, I've done very little; I installed a few packages (samba, xemacs, etc), and I let the system update itself. The update installed 'kernel', and updated 'kernel-firmware' [URL]. I now need to install the dev tools (g++, and so on), but I can't. I've tried this from gpk-application, and directly from yum. The complete yum output is below, but the basic error is:
> Error: Package: glibc-2.12-1.7.el6.i686 (sl)

Ubuntu :: Check Harddisk And File Integrity?
Aug 12, 2011I want to get a program to check (a) hard disk and (b) file integrity. I have had a file - ODS spreadsheet accessed using LibreOffice - that appears corrupt. I have drilled down and down and eventually identified a corrupt component image inserted in a sheet.
The error that is thrown by LO is a "Error saving
the document FILE: Write Error. The file could not be written."
error. The thread can be read here... http://thread.gmane.org/gmane.comp.d...fice.user/9266.
What has confused me is that my machine can not save the file once a sheet is deleted. It is specific to a particular file. The file is stored on n ext4 disk mounted by fstab. I also share the file using samba. Regardless of how I access this file I get the error. If however, I access the exact same file using OpenOffice 3.1.0 OOO310m11 (Build: 9399) from an old Windows Vista Tablet and I can manipulate the file successfully - no error is encountered. I can also access the same file from another Ubuntu machine via NFS and Samba and both work. I am confused. I am beginning to think my disk is damaged or something. How do you check hard disks to verify that the disk surface is intact, and that the expected file sum value matches the value stored in the Linux equivalent to the FAT table.
I am using Ubuntu 10.04 LTS and all hard disks are formated with ext4. All formatting and management of the disks have been done using the 'Disk Utility' in the System > Administration' menu. If I look in gparted it will not check the disk the file is on stating "eslabel: no such file or directory... couldn't find valid filesystem superblock...". The filesystem mounts OK however without any errors. Another harddisk on the same system currently being used for backup does not even have the menu option for checking the disk highlighted.
What is the best way of verifying the integrity of the filesystem, actual files and the underlying physical media? I should point out it is only this single file that currently displays any issues. I either have a damaged disk, corrupt file or LibreOffice has a very peculiar bug that only appears in a unique combination of events just on my machine. As part of my investigations I have been updating ubuntu, reinstalled LibreOffice from their website and checked all dependencies have been met.
General :: Can I Do Integrity Check When Tar.gz File Is Created?
Mar 25, 2011create one tar.gz file that contains my /home, /etc, /root directory.
a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.
b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)
c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?
d) How can I do an integrity check when my tar.gz file is created?
Debian :: File Integrity For Backups Of Home Data ?
Nov 17, 2010I'm currently backupping our home data (pictures, videos, our CDs ripped to FLAC which I spent a lot of time to tag accurately ), totalling almost 300 Gb, on 2 external USB drives, one of which is meant to stay at a friend's. I left the factory msdos filesystem as it was, thinking it could be useful to be able to connect the drives to a windows machine with no problems. It's certainly useful to have «normal» data that I can take with me e.g. when visiting my family.
I'm simply using rsync manually, checking for suspicious changed or deleted file before commiting the change. I do that every 2 weeks or so.
Now I want to add a file integrity management to my backupping scheme: I want to be able to check that new data I'll be committing has not been tampered with (integrity check before updating tags on my main drive), and I want to be able to check that backupped data is still sane on my USB drives, especially if I need to recover from data corruption on my main drive.
Since I'm essentially mirroring the data, I thought run of the mill integrity software would let me just rsync the integrity database, and I'm done.
But after browsing through the docs of tripware, afick and the like, I fear they work only with absolute paths, so the database for my main drive wouldn't work for my USB drive, that's mounted elsewhere when I plug it in, obviously.
So, I feel I'm missing something. It looks to me I'm trying to solve a very common problem, how do people do it?
Did I miss a file integrity software that works with backups?
Is there a trick like using a symbolic link pointing to whatever file hierarchy I want to check, and have tripware/afick/... monitor that link?
Should I run a more elaborate backupping system than plain rsync? Which one? (Storebackup for instance looks promising since it involves md5 sums, but it's targetting a completely different problem, and I'm not sure I can use it at all for what I need.)
Security :: Checking What Processes Are Hidden?
Jan 13, 2010I post this to have a memo about how I looked into this problem. You can use this command to check what is hidden.
Code:
/usr/lib/chkrootkit/chkproc -v -p 3 | grep /proc/ | sed 's/.*(/proc/[0-9]*).*/1/'| xargs -n1 -I %%% cat %%%/cmdline
If it doesn't output anything, then nothing is hidden currently. This usually means that a process was started between the ps command and the /proc check of chkrootkit. You can check what those command(s) are by running the above in a loop, with high priority.
[Code]...
Does anyone know how to get rid of these false positives while retaining other functionality of chkrootkit?
Ubuntu Security :: Checking The Signature For A Package *before* Install It?
Jul 21, 2011I'm interested in GNU/Tiger as recommended by a security guru I know. I did apt-cache search and located the package tiger:Code:tiger - Report system security vulnerabilitiesI also checked the ubuntu web-based package search and found tiger there too along with things like this signed message.Using apt-cache policy, I see this package is universe. I'd like to check the signature/cert/keys of this file before running apt-get install on it to see if it is acceptable given my current apt keys. Can someone explain how to do this?Also, what happens when I try to install a package using "apt-get install" and that package or one of its dependencies is:* unsigned* signed, but not by anyone whose key resides in my apt keyring?

Ubuntu Security :: Checking If Anyone Is Viewing Passwords Stored In FireFox?
Jun 16, 2010As 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.
Ubuntu Security :: Deny Hosts Removing An Ip And Checking Tcpwrappers?
Oct 21, 2010I could not find any where the documentation the only best which I got was [URL]
My question is the following blog says to remove an IP from /etc/hosts.deny which denyhost has blocked
[URL] you need to have a directory /usr/share/denyhosts/data I do not find any such directory
Also when I tried to check tcp wrapper configuration as given here
[URL]
tcpdchk -v Cannot find your inetd.conf or tlid.conf file. Please specify its location.
what does the above output mean? How do I make sure denyhosts is doing its job?
Server :: Easy File Sharing On Windows... Without SMB?
Jun 16, 2010Question for the sys admin types:So, say you want to do file sharing in an environment with a lot of Windows clients, but you want the shared data on a Linux server. You can use SAMBA, and that will make all the Windows clients happy (provided, of course, that you can get SAMBA working correctly). But is this your only option?I mean, obviously you can use ssh/sftp. But the Windows sftp clients I have tried don't make the file sharing process as simple for non-techies: you either just get a command-line, or you get some kind of two-pane application view like with filezilla or cuteFTP; it isn't as integrated into the desktop as what you get when using native SMB file sharing.So, is there Windows software you can install that can make the file sharing experience very non-expert friendly with some protocol like ssh/sftp or NFS?

Mar 30, 2010I'm using Gnome for the first time (after a long time with KDE) and am trying to share a folder the easy way. After installing nautilus-share (and samba, samba-common and samba-common-bin)I can right click on a folder and make it shared. Problem is that the option 'Guest access (for people with no user account)' is always grayed out.On some Ubuntu forums I saw people fix it by purging and reinstalling samba but that didn't work for me.I know how to manually setup a share in samba, just want to figure out why this isn't working and how to get this going.

Apr 12, 2010I downloaded the DVD ISO version of OpenSuSe version 11.2 64bit from openSUSE. I checked the iso file checksum after downloading and it was correct. However after burning to DVD i booted from the disc and started the install. After getting passed the initial settings and it starts to extract all of the packages each file fails the checksum and will not install. I tried downloading again on a different computer and burning again using UltraISO using the Disc-At-Once method, again checking the ISO file's checksum before burning.
It still gives the same errors. So i loaded windows and started the windows based install and my anti-virus (Kaspersky) says the disc is infected with a trojan. How can the disc be infected when the ISO file's checksum is correct?. The computer that i am using to burn the disc is virus free according to Kaspersky and Norton Technician Toolkit.

Status for ACCOUNT_MISSING_FRM_RCIS_LINK is ACCOUNT_MISSING_FRM_RCIS_LINK- does not exist in DB
This should appear just once as :

The same goes for last line.
For further information the ACCOUNT_MISSING_FRM_RCIS_LINK is a table name and it row count is taken from a log and then Database checked for the rowcount to see if it is a match,mismatch,or the table does not exist!
