I'd like to know if something like this already exists :have an ecryptfs encrypted user account on a laptop that accepts two logins, 1st logs normally, the second triggers a system format

I wonder if it is possible to have two passwords for one user account in 9.10. I have a long login password (5 words about 45 characters with spaces caps). I would like to set a shorter password for Authentication, sudo, etc. While retaining the original for logging in.In short:Have long password to login to computer.Have short password for everything after login.

View 6 Replies View RelatedI am not very security minded...I'm aware of it, and always made sure I had up-to-date overall protection in Windows but firewalls, and the blasted passwords are largely a thorn in my side!When I got my iPhone last year I suddenly discovered password managers & "wallets" to keep all that kind of information in and syncable across different devices. My life got so much easier. Of course now I need to figure out encryption keys, and how they work (I'm clueless). I also need to find a program or system that I can move my existing low-tech info (mailnly user name & passwords) that will also accomodate the increased needs of Ubuntu security and still be sync-able. I started a little research weeks ago, but my current "wallet" only exports .csv so I quit since I'm going to have to do a lot of data entry whatever I go with.So here goes:
1) what is the difference (bare bones) between using an encryption key (e.k.) vs. a standard user created password? what situations are better suited for e.k.?
2) I have seahorse (default intall with Ubuntu I guess) but the only thing in it is Login under passwords which leads to a login keyring (?) and a drop-down list of about 6-10 of the gazillon passwords I use daily. The other tabs are for keys which I don't have any concept of.
3) I know FF also "remembers" user id & passwords as you choose to have it do so. Is that information transferable into seahorse or another program?
4)I'm also (today) getting ready to really set up my system for user names & security across my little home network. How can I integrate that into whichever program/app I go with to store my pwds and keys?
5)give me links to fairly current documentation on this stuff?
6) Any program/app recommendations.Pros/cons uses, what they can & can't do or be used for, etc.

Is gpg -c <filename> secure enough ? And what FAST distro would you install on it? I'm learning on old USB flash and found SliTaz pretty damn cool,I use it as a LiveUSB. Also I've tried Kubuntu but it's bit slow. Going to try Lubuntu soon too. Any other idea?
And I'd like to install some FAST distro onto new 8GB mini USB flash drive,maybe Kubuntu as well. How would you partition its Flash drive? Probably separate partition for stored encrypted files?
I use Ubuntu on my netbook, which I uses for browsing and email. It's way faster than the Windows which came on the machine. That's a nice feature, as is the price.
I like it except for the constant, perpetual, ever-present, super-annoying need to be entering passwords and "becoming root user" and so on. I am the only one using this appliance. I don't even care if someone steals it, really. There must be some way (I hope) of disabling this idea that I am a CIA agent with TopSecret materials.
I just want a simple, easy to use appliance. If not Ubuntu, is there any distro that is aimed at normal people?
Is it possible to have two passwords associated with one account, one that is the actual one, and another one, a duress password, that upon entering gives a similar (desktop) environment with "decoy data"?
The idea is to have the bogus password go to an encrypted home drive that looks as if it were the real deal, but it is wiping particular sensitive (encrypted) data that is visible only with the real password in the background, so that the actual data that need to be protected are not compromised. While the person who unlocked the computer tries to find the information on it between all the rubbish files, the real files are securely wiped. The files are very sensitive in nature, so it's better to have then destroyed than have unauthorized people access them, in the event of that happening.
I happen to know that TrueCrypt has a similar option but that requires an entire decoy operating system (and I think that might be a bit conspicuous), but is there a native linux way to do it?

View 2 Replies View RelatedI would like to be able to store all my important details and passwords in such a way that it is encrypted, easy to get the information out and is cross-platform. Basically, I am thinking that if I kick the bucket that I would like to make it as easy as possible for others to be able to access this information using a pre-arranged password.
Ideally I would like the files to contain the program that is needed to extract the data i.e. importantinfoLinux.sh inportantinfoWin.exe (Just like a self-containing zip). I haven't found anything along those lines.
The things I am currently thinking of is:
1) A password database program that is cross-platform like KeePass. WIth the bundle contining the relevant installers for win, linux and OS X and the database file.
2) An AES encrypted zip of the data with relevant programs to open it e.g. 7-zip on windows, peazip on linux and OS X
Has anyone got any thoughts on this? Any self-containing java encryption apps?
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.
if you go to Edit > prefs > security and choose to show saved passwords they are displayed without entering root pw. This seems to be a huge security hole. How do we fix this?
View 8 Replies View RelatedThe ubuntu installation came with my ubuntu (it does not matter which version etc.) Contains sshd_config file with this interesting lines:
# Change to no to disable tunneled clear text passwords
#PasswordAuthentication yes
The same lines are seen in many Ubuntu-related internet pages. This is quite surprising to see.
This seem to contradict to the fact that ssh was created specially to provide authentication (with passwords, of couse) but without sending them by internet as clear text like previous programs did. But I could not find any clear confirmations of that neither in Kubuntu-related documents no anywhere else. I put below fragment of a document from RedHat. This seem to imply that if one will use two "yes", the passwords will be passed in encripted form (and this is what is recommended by RedHat). Is that true? Is this true for Ubuntu too? Is the quoted line from sshd_config wrong? Or incomplete?
[URL] RSAAuthentication yes
The option RSAAuthentication specifies whether to try RSA authentication. This option must be set to yes for better security in your sessions. RSA use public and private key pairs created with the ssh-keygen1utility for authentication purposes.
PasswordAuthentication yes
The option PasswordAuthentication specifies whether we should use password-based authentication. For strong security, this option must always be set to yes.
Sitting at the console, I log in with any user name and NO PASSWORD IS REQUESTED. I get logged in automatically without entering the user's password.
I did:
passwd joeuser
To change his password and still he goes right in without being asked for a password!
Possibly related- 10 days ago, my smtp server was breached as a spam relay. The username they cracked was deleted. I added fail2ban for postfix. The logs show no further intrusion.

I used to dual-boot, windows 7 and Ubuntu, but like a month ago, i decided to finally kill windows, so when i finished doing so, i had 160 GB. of free space. I never resized my ubuntu partition, since it had like 80 GB. of free space.Yesterday, I re-compiled my kernel, mainly to enable FrameBuffer in the console. So i decided it was time to resize my partition, to use the whole HDD.Turns out, that i had a little bit of problems compiling my kernel, and yes it took really a lot more than i thought ( I had to compile it twice ) but finally i got it working.
i still got some 100 GB. free, so is there anyway to get my system to it's normal weight?.I really don't wanna miss all my info, specially my programs, and customized desktop, it really took me a wile to set compiz just the way i like it.IM REALLY SORRY, I KNOW IT WAS MY FAULT, BUT I REALLY DON'T WANNA LOSE ALL THAT GB. NOR MY SYSTEM.
I followed this howto in order to mount CIFS shares on demand. This works great, however, this guide suggests leaving my network passwords unencrypted on the disk. This is a very bad security practice, as the passwords can be easly retrieved by booting the computer using a different OS.
I was looking for a way to secure things up, so I came up with this solution: Instead of storing the passwords plain text on the disk, I store them in a tar file encrypted using GPG. When I boot my system, I open this file to a directory in /dev/shm, and order AutoFS to retrieve the passwords from there.
This does the trick, but I presume this solution is not that secure, since /dev/shm content can be written to the swap partition. Is there any other solution which is a better security practice? Maybe using some sort of keyring service?
Got a used Lenovo Thinkpad r61i and put Ubuntu 9.10 on it. Every time I turn it on it prompts me to give it a password for someone else's internet. This a password I do not know and I use an ethernet cable for internet so it's really annoying. Any way to make it stop?
View 1 Replies View RelatedI'm planning to centralize users and passwords and also create controls for user access to some equipment, for example, Linux Servers, Switches, routers and firewalls. In case of failure of the link between the ACS and AD or equipment to the ACS, this device would use local username and password.
At the moment, my AD structure is a Microsoft, Cisco ACS servers and Linux Standalone. I wish that both linuxs servers and network equipment were authorized by Cisco ACS on the accounts that are in Microsoft AD.
The configuration of the Cisco ACS to use the AD is done and no problems, the network equipment is OK too, but am having difficulties configuring the server for this solution.

I was under the impression the Linux (in my case the Fedora OS) is very secure. However I've learnt with deep concern that that one can have access to the system during system startup i.e one can give various startup directives and bypass the normal login UI to have direct root access.
Is there a way to disble this so that the directives during startup are fixed and cannot be altered. I would like to make the system secure to the maximum extent possible.
