Security :: Console Users Logging In Without Passwords?
Jul 19, 2010Sitting 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.
Security :: Permitting Users To Ssh With Out Typing Their Passwords Via Kerberos?
May 24, 2010Is there a way to use kerberos (or baring that a trusted CA) to allow users to ssh across machines in an environment isntead of having to manage the hash keys per user/server? I'm using kerberos+ldap to log folks in and get their settings but I'd like to take it a step further. I've been reading a lot but still can't quite get it all to come together.
Do I need to create a SPN for each host to do this? Sorry if I am asking a dumb question, I am returning to the *nix fold after a decade+ in the Microsoft world, be gentle with me.
Security :: Centralize Users And Passwords And Also Create Controls For User Access To Some Equipment?
May 12, 2011I'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.

Mar 2, 2010I am trying to set up Ubuntu like I had on my windows PC. I have my account, my wifes account and my kids account. I want passwords set for both myself and my wife but I don't want the kids to be required to have a password to log in. When setting up Ubuntu, it looks like it was all or none. I have dabbled with Linux off and on for years and am sure there is a way to set this up but I have no idea how.
View 8 Replies View RelatedUbuntu Security :: Security, Passwords & Encryption Keys?
Jun 7, 2011I 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.

Ubuntu Installation :: Restore Users & Passwords?
May 4, 2011I upgraded from 10.10 to 11.04 (32 bit) with a clean install as the "upgrade" option in update manager failed. I'm setting up the system again and want to restore the backup I took prior to upgrading, however due to the upgrade I don't want to just re install everything. The following have been backed up
/etc
/home
/usr/local
/var
Now there are various things that are different such as firefox 3.x has become firefox 4 Open office is gone, long live LibreOffice, my proprietary Nvidia drivers don't seem to be trusted yet, all the repositories will be different etc. I will re install all the applications fresh from the software centre, but I would like to restore all the users and passwords and their home directories,
So I don't I want to restore /etc or /usr/local en masse. I guess /var is not worth restoring either /home gets me their files but how do I restore the users and passwords? (there are about 8 registered users some of whom have different privileges) and the user ID need to be the same as they all access a NAS through nfs)
General :: Viewing Counts Of Old Passwords Associated With Users

I have set remember to 24 in the /etc/pam.d/system-auth file. I don't know where the file is that contains this information.

View 6 Replies View RelatedSoftware :: Import Windows Users / Passwords Into Openldap Server - Ldap Migrate Migration?
Nov 18, 2009I am looking for ideas for getting windows users into an ldap server. I am currently running a Linux server for my department and need to create an LDAP server which mirrors the username/password information for all of us as they are stored in the windows server here. I have the openldap server up and running on Ubuntu 8.04 and it works great; I now need to find some way to import user info into this from windows. I've seen discussions of using ldifde.exe to export the AD users into an ldif file. Is this the simplest way to go about it?
Our Linux server is currently providing us with much needed services using apache, and apache is authenticating using LDAP to our windows server (Using our windows username / password is required functionality). This windows server has some problem which causes it to delay for inordinate amounts of time between authentication requests and responses. The situation is such that this problem will not be addressed by IT staff. However, I have control over the Linux server so I am looking to just mirror the windows server on an LDAP server of my own. I could get away with updating the passwords in the Linux server.
Fedora :: To Make Remember My Passwords?
Mar 6, 2011I'm having some problems of security in my Fedora 12... excess of security. It keeps me asking mi password everytime I want to perform an operation, and in some cases I'm pretty sure that this hampers me to work with some files.
Everytime I boot it, it asks about the password for the wireless network, and when I fill that out, another window pops up saying "Enter password for default keyring to unlock" (I press the "deny button" always for this one as it doesn't accept my user password.
I'm a newbie in linux and in programming, so I spend the days facing problem after problem and it's starting to drive me crazy. I'm not the root of the computer, but just a superuser (I hope that's not the problem)
Isn't it possible just to put my password when I start and then work without writing it anytime?

View 3 Replies View RelatedGeneral :: Disable Passwords And Security?
Dec 15, 2010I 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?
Security :: Encryption - Two Passwords Associated With One Account ?
Mar 11, 2011Is 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?

Feb 21, 2011I have a vsftp server running, and we have problems sporadically where people (not the person who uploaded the file) cannot delete files uploaded from OSX machines. We never have this problem with files uploaded by PCs. Anyone ever heard of this or know what I should check? The users uploading the files all belong to the same group. Also, I think if you log in to the FTP server with another OSX machine, it will let you delete them. I'm looking at the folders now, they have drwxrwxr-x. When i try to delete them from a PC, it gives me a 550 Remove directory operation failed.
