• Contact YouTube

  - by takeshin

  Is there any direct way do contact a „real” person, an YouTube employer? Someone created an account for the company I work for (previous employer). She entered some password and e-mail. The provided e-mail was valid, but since last login (more than two years), we changed our domain, and this e-mail is probably not valid anymore (and we even don't know it), co we can't use option to reset password. I have used all the options in YouTube help center, and no one worked. Also we can't contact this previous employer to get any data she entered in the registration form. The only data I know is the username. All the movies present the products of our company, there are links to our site in movie descriptions, so there should be no problem to prove that the account is ours. This is an urgent case, becouse the movies contain outdated information.

• Mount encrypted volumes from command line?

  - by cha

  If I have an encrypted external disk (or an internal disk that is not in fstab), I see an entry for it in Nautilus -- with an entry like "X GB Encrypted Volume". I can click on this volume, and am prompted for a password to decrypt and mount the device. But how do I do this from the command line? This wiki page, and other docs I can find, only refer to GUI methods of decrypting the device; but this won't do in the context of headless servers or SSH logins. Is there a simple way to get devices to mount to automatic locations in "/media" just like they would with the GUI? (I'm not asking about encrypted home directories -- I'm aware of ecryptfs-mount-private. This question is about additional encrypted volumes.)

• Software Center doesn't ask for a password anymore

  - by Jeff

  So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.

• Sudo Non-Password access to /sys/power/state

  - by John

  On my computer, pm-hibernate appears to be broken, however using the command echo disk > /sys/power/state appears to work perfectly. Now I just need regular user access to it, using sudo. How do I do this? The command sudo echo disk > /sys/power/state simply returns bash: /sys/power/state: Permission denied. Also, I need this in a regularly used script, how can I make it so that I don't have to type in my password for it to work???

• UEC - Unable to SSH into instance, asks for password

  - by nijanthanh

  I am attempting to set up a private cloud using Ubuntu 10.04.4 Server. I am following the tutorial at http://cssoss.wordpress.com/2010/11/26/eucabook-v1-1/ . All steps go on perfectly apart from that I am unable to SSH into the running instances. I have created the instance using a public key and try to SSH into instance using the private key. However it asks for password. I am able to ping the instance though. I have tried using both the pre-built images from the store as well as custom built images. Several people seem to have the same problem but there does not seem to be any working solution. Thanks in advance.

• No user/password boxes on login screen after updates today (June 30, 2012)

  - by Tony

  Just installed today's batch of updates, including new kernel 3.2.0-26 and rebooted. Now the screen just has a logo in the middle and "Ubuntu 12.04 LTS" in bottom left corner, but no box to choose which user to log in as, or to enter a password. CTRL-ALT-F1 gets me to a "login:" prompt, and I can log in - but I have no idea what to look at to find out what is wrong, or to fix this. Tried older kernels and recovery mode for current kernel - no joy, still no way to log into the graphics console.

• How To Remotely Copy Files Over SSH Without Entering Your Password

  - by YatriTrivedi

  SSH is a life-saver when you need to remotely manage a computer, but did you know you can also upload and download files, too? Using SSH keys, you can skip having to enter passwords and use this for scripts! This process works on Linux and Mac OS, provided that they’re properly configured for SSH access. If you’re using Windows, you can use Cygwin to get Linux-like functionality, and with a little tweaking, SSH will run as well.What is a Histogram, and How Can I Use it to Improve My Photos?How To Easily Access Your Home Network From Anywhere With DDNSHow To Recover After Your Email Password Is Compromised

• usb keyboard stopped working in terminal window after update from 13.04 to 13.10

  - by Jim

  When I start the computer, I am logged in automatically. Using the keyboard, I type Ctrl+Alt+t, which brings up a terminal window, just like it should; however, nothing happens when I attempt to type into the terminal. If I change over to the guest account, I can type into the terminal, but (different problem here, I'll ask it separately unless someone is kind enough to answer it here) my password doesn't work for sudo or anything else. Elsewhere I read that Language support could fix it, but that won't accept my password either - and no, I haven't changed it lately. Also, my Plex Media Server seems to have disappeared. I'll re-install everything if necessary, but I sure would rather avoid that if possible

• How secure is KeePassX?

  - by Uli

  I have hundreds of passwords, since I use a different random one for each website/service. They are all generated & stored with KeePassX, which can be synced to different computers and my android phone via dropbox (or ubuntuone). I know the database of KeePassX is secure (at least with a good passphrase). But what about when I am copying the password into the clipboard (where it is stored for 5 seconds)? Can any program running in user-space access the clipboard and store the password? If so, how big of a security risk is this?

• Cannot connect to wifi after downloading 12.04, repeated prompts for password

  - by Daytown3487

  I have had this OS for a little bit but this is my first upgrade and my first issue I am trying to deal with without my buddy who got my on Ubuntu in the first place (who is on the other side of the country.) I am running an IBM Lenovo T400 Thinkpad that had 11.10 on it and worked flawless. I upgraded to 12.04 a few weeks back and I have not been able to connect to the wifi in my home or anywhere for that matter. I have been trying to mess with it through reading the forums and am not quite sure what my problem is. I am running off of Fios Internet and the wifi keep disconnecting and prompts me to retype the password for reconnecting. If you guys could give me a step by step process of how I should go about fixing this I would GREATLY appreciate it!

• Is the php method md5() secure? Can it be used for passwords? [migrated]

  - by awiebe

  So executing a php script causes the form values to be sent to the server, and then they are processed. If you want to store a password in your db than you want it to be a cryptographic hash(so your client side is secure, can you generate an md5 using php securely( without submitting the user:password pair in the clear), or is there an alternative standard method of doing this, without having the unecrypted pasword leaving the clients machine? Sorry if this is a stupid question I'm kind of new at this. I think this can be done somehow using https, and on that note if a site's login page does not use https, does that mean that while the databse storage is secure, the transportation is not?

• bash script ask for root password

  - by VinceBrowning

  I want have a script that I can give to friends which will add repositories and download files, install them without having to use command as they are not command line savey and have no desire to learn. I need to know how to get the script to prompt them for the root password to allow them to do some of these functions. How would I go about this? Please don't hate on them.. Getting them to start using Linux was a big step and I am just happy that they are attempting something new... and it was in the open source world..

• I started getting a weird message "Encrypting file system - Back up your file encryption key"

  - by user22559

  Hello I started getting a strange message when I start my computer. An icon appears in the system tray, and a popup tells me "Encrypting file system - Back up your file encryption key". I know what EFS is, but I don't use it. To my knowledge, I don't have any encrypted files on my partition. I have searched using Total Commander on all the partitions for files that have the "encrypted" attribute, but I found nothing. So I don't have any encrypted files. Does anyone know what I did to get this message?

• SSLCipherSuite - disable weak encryption, cbc cipher and md5 based algorithm

  - by John

  A developer recently ran a PCI Scan with TripWire against our LAMP server. They identified several issues and instructed the following to correct the issues: Problem: SSL Server Supports Weak Encryption for SSLv3, TLSv1, Solution: Add the following rule to httpd.conf SSLCipherSuite ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM Problem: SSL Server Supports CBC Ciphers for SSLv3, TLSv1 Solution: Disable any cipher suites using CBC ciphers Problem: SSL Server Supports Weak MAC Algorithm for SSLv3, TLSv1 Solution: Disable any cipher suites using MD5 based MAC algorithms I tried searching google for a comprehensive tutorial on how to construct an SSLCipherSuite directive to meet my requirements, but I didn't find anything I could understand. I see examples of SSLCipherSuite directives, but I need an explanation on what each component of the directive does. So even in the directive SSLCipherSuite ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM, I dont understand for example what the !LOW means. Can someone either a) tell me the SSLCipherSuite directive that will meet my needs or b) show me a resource that clearly explains each segment of a SSLCipherSuite is and how to construct one?

• strategy /insights for avoiding document content loss due to encryption

  - by pbernatchez

  I'm about to encourage a group of people to begin using S-Mime and GPG for digital signatures and encryption. I foresee a nightmare of encrypted documents which can no longer be recovered because of lost keys. The thorniest issue is archiving. The natural way to preserve privacy in an archive is to archive the encrypted document. But that opens us up to the risk of a lost key when time comes to unarchive a document, or a forgotten password. After all it will be a long way in the future. This would be equivalent to having destroyed the document. First thought is archiving keys with documents, but that still leaves the forgotten pass phrase. Archiving the passphrase too would be tantamount to archiving in the clear. No privacy. What approaches do you use? What insights can you offer on the issue?

• Unable to use strong encryption

  - by user224299

  So I am exploring Apache to create a simple example: the default page and a directory "secure". I everyone to be able to access the server but, when one wants to access the "secure" directory, I the connection to use strong encryption. I am using apache2.4. However this is not working and I don't know why! I have done just like in the Apache tutorial: LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl.so <VirtualHost *:443> SSLEngine on SSLCertificateFile /home/vitorpereira/Desktop/cert.cer SSLCertificateKeyFile /home/vitorpereira/Desktop/key.key </VirtualHost> SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL <Location /var/www/html/secure> SSLCipherSuite HIGH:!aNULL:!MD5 </Location> But this does not work :/ And, I can access the secure folder with http but when I write https, it says not found!

• Submit WordPress form password programmatically

  - by songdogtech

  How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

• ASP.NET Membership C# - How to compare existing password/hash

  - by Steve

  I have been on this problem for a while. I need to compare a paasword that the user enters to a password that is in the membership DB. The password is hashed and has a salt. Because of the lack of documentation I do not know if the salt is append to the password and then hashed how how it is created. I am unable to get this to match. The hash returned from the function never matches the hash in the DB and I know for fact it is the same password. Microsoft seems to hash the password in a different way then I am. I hope someone has some insights please. Here is my code: protected void Button1_Click(object sender, EventArgs e) { //HERE IS THE PASSWORD I USE, SAME ONE IS HASHED IN THE DB string pwd = "Letmein44"; //HERE IS THE SALT FROM THE DB string saltVar = "SuY4cf8wJXJAVEr3xjz4Dg=="; //HERE IS THE PASSWORD THE WAY IT STORED IN THE DB AS HASH string bdPwd = "mPrDArrWt1+tybrjA0OZuEG1P5w="; // FOR COMPARISON I DISPLAY IT TextBox1.Text = bdPwd; // HERE IS WHERE I DISPLAY THE return from THE FUNCTION, IT SHOULD MATCH THE PASSWORD FROM THE DB. TextBox2.Text = getHashedPassUsingUserIdAsSalt(pwd, saltVar); } private string getHashedPassUsingUserIdAsSalt(string vPass, string vSalt) { string vSourceText = vPass + vSalt; System.Text.UnicodeEncoding vUe = new System.Text.UnicodeEncoding(); byte[] vSourceBytes = vUe.GetBytes(vSourceText); System.Security.Cryptography.SHA1CryptoServiceProvider vSHA = new System.Security.Cryptography.SHA1CryptoServiceProvider(); byte[] vHashBytes = vSHA.ComputeHash(vSourceBytes); return Convert.ToBase64String(vHashBytes); }

• How to encrypt/decrypt a file in Java?

  - by Petike

  Hello, I am writing a Java application which can "encrypt" and consequently "decrypt" whatever binary file. I am just a beginner in the "cryptography" area so I would like to write a very simple application for the beginning. For reading the original file, I would probably use the java.io.FileInputStream class to get the "array of bytes" byte originalBytes[] of the file. Then I would probably use some very simple cipher, for example "shift up every byte by 1" and then I would get the "encrypted" bytes byte encryptedBytes[] and let's say that I would also set a "password" for it, for example "123456789". Next, when somebody wants to "decrypt" that file, he has to enter the password ("123456789") first and after that the file could be decrypted (thus "shift down every byte by 1") and consequently saved to the output file via java.io.FileOutputStream I am just wondering how to "store" the password information to the encrypted file so that the decrypting application knows if the entered password and the "real" password equals? Probably it would be silly to add the password (for example the ASCII ordinal numbers of the password letters) to the beginning of the file (before the encrypted data). So my main question is how to store the password information to the encrypted file?
