View 1 Replies View RelatedUbuntu Security :: 9.04 Jaunty Encrypted Account And Password Changing?
Mar 10, 2010When I first installed 9.04 (from scratch), I chose the option to have my entire account encrypted... I used the same password as my login password, and wrote down the key hash that it displayed for me just like instructed... everything was working terrific...Well, yesterday, I wanted to change my account password. I changed my account password, and it took effect immediately (I tested it by using "sudo -s" to see if I could elevate to root from the terminal... worked just fine). Being satisfied with my new password, I shut my computer down...
The next time I started it up and tried to log in to my account, it I put in my username and password and pressed enter, and it accepted it just fine, and started to boot to my desktop... it then immediately prompted me with something about "your session lasted less than 10 seconds, try starting in failsafe mode" or something along those lines, and immediately booted me out and back to the gdm login screen... I thought it was just a glitch so I tried again... same thing... gave me the "less than 10 seconds" prompt and booted me back to the gdm...
I thought maybe my filesystem became corrupted, but I didn't give up... I attempted to login to my fiancee's account, and it worked just fine! Using her account, I was able to quickly and safely boot into her desktop environment with no errors...I opened a terminal and used the "su" command to access my account... When I did this, it gave me some kind of error and told me to run ecryptfs (can't remember exactly which command... now). I ran ecryptfs and put in my NEW password... it told me that the passphrase was incorrect. So just out of curiosity, I ran it again, and this time put in my OLD passphrase, and it worked immediately! At this point, I realized that my gdm login password got changed, but my ecryptfs passphrase did not, and the two were not matching up (I assume that on login, gdm passes this password on to ecryptfs, and that when the two did not match up, it was booting me out with the whole "session lasted less than 10 seconds" prompt...)...
So what I did at this point was, while logged into my girlfriend's account, I "su"'d into my account, and used the passwd command to change my password back to my OLD password... once the password was changed back successfully, I restarted my computer and tried to log into my account from the gdm... worked perfectly this time with the old (original) password...When you change your session password, shouldn't it automatically change the encyrption password to match? Or at the very least, warn you that if your account is encrypted, you must take further steps to make these two passphrases match? Also, what command would I use to change my "ecryptfs" password to manually match my session password?
Ubuntu Security :: Resolving An Account Password With Pam-script When Using Passwordless SSH? Possible?
Oct 6, 2010I'm trying to configure a process triggered by an SVN post-commit hook which will log into a different host and carry out an SVN update on a file path on that host before exiting. An earlier attempt mounted the remote filepath on the SVN host using sshfs and performed the update locally. This worked but it was incredibly slow (minutes to complete an SVN update).
So, Plan B was to set-up a passwordless login for the user the script runs as and then use pam-script to script a checkout from a repository using the same credentials. The problem is, passwordless SSH login using private/public keys appears to bypass the PAM authentication system or at least interact with it in a way that no environment variables (including the SSH user's name and pass) are resolved by the authentication script being used by pam-script.
I've tested the pam-script behaviour for normal log-ins and it exposes these variables fine. This leaves me in a Catch-22 with trying to script access on one host to perform actions on another while avoiding user/pass prompts or the need to store plaintext passwords on the remote host.
Anyone know if there's a way to resolve a user account password via PAM when using passwordless SSH or, another approach I could take to perform scripted tasks on the remote system requiring authentication? Ideally without storing the passwords on the remote system (at least in unencrypted form).
Ubuntu Security :: Unknown User Account 'dtc'?
Mar 12, 2011I started up my computer and suddenly, I saw that there was a new user account. I didn't create it and no one else uses my computer (let alone has access to user account creations). It was called dtc. It didn't seem to have any privileges and the only file in its home folder was called Examples. Should I worry that I might have some kind of malware? I deleted the user and the folder (and it came back after a while). It's main group is dtcgrp. The User ID is 1004.

Feb 15, 2011I suppose that my main Linux user account password serves as my SSH password as well. Is there a way I can modify this? As it turns out, I'd like to have a REALLY secure SSH password for obvious reasons, but a less secure local password, as it makes typing in passwords a heck of a lot easier on a machine. Is there a way I can change my account password in SSH without changing my Linux user password?

Ubuntu Security :: When Logged Into Every Day Account And Tried To Load The Program, It Prompted For Password?
Jul 8, 2010I installed IPlist earlier today on my main/admin account (which I only use for installing programs. I don't use this account daily.) and everything was fine. When I logged into my every day account and tried to load the program, it prompted me for my password. When I entered it, I got this message:Quote:Failed to run /usr/sbin/ipblock start_gui as user root.The underlying authorization mechanism (sudo)t allow you to run this program. Contact the system administrator.Does this mean I am not able to use this program on this account, or is there a way around it? I'm new to Ubuntu so forgive me if I'm asking the obvious. I looked around and couldn't find an answer. I really don't want to use my admin account for daily activities, but I also really want to be able to use IPlist
View 2 Replies View RelatedUbuntu Security :: Running Wine Under A Different User Account?
Jan 2, 2010I've written an article on my site which lays out steps for installing Wine and running it under its own, separate user account, so that Windows applications cannot access personal files (particularly those in your home directory).[URL}..i'm hoping that there are people on this forum who know Ubuntu inside-out, as I'd like to know how effective the described method is at trapping Windows applications so that they cannot read or write personal files or directories.
The way I understand it, once the process is running under user account wine, it's stuck with the access privileges of user wine. But are there ways in which a rogue application could break out of this prison and gain access to whatever it wishes? I'm guessing that such behaviour would mean someone customising Windows software to recognise Linux, and that such a thing is very unlikely, but I'm still interested to hear what gurus of the Ubuntu internals think of this method.

Software :: Allowing User To Change Their System Account Password From Intranet?
Jan 10, 2011I have configured httpd web server to allow each of the system users to have their own web page (using UserDir directive).At the same time I have configured ftp server to allow the users to upload their html files to the web server.With above set up my users need not have any knowledge of linux; they can work from any windows PC on the network.There is no problem in the above.However, now I need to allow my users to change their passwords. The point here to note is that the users should be able to do this even from windows PC on the network. One of the way is to configure a telnet server (or sshd). But I find that the windows PC does not have telnet client.The other idea is that I should put a php script on the server which would take user name and password from the web page and then change the password. I don't know how can the system account password be changed through script - I will have to check this out.

Mar 13, 2010I want to jail Skype into its own process and not the one I login with. That way, if a hacker breaks in, it's limited to this process and only the limited functionality that that user account has. The thing is this -- thousands of Linux guys run Skype, but Skype is hardly ever updated or have security patches, and we run it all the time. It seems like an easy avenue for an exploit. As well, my iptables firew all blocks input connections that I have not established, but Skype is an established connection. How do I create a Bash script that launches Skype under a separate user account?
