• Error [9783] Support for cores revisions 0x17 and 0x18 disabled by module

  - by iamzarnywoop

  At start up after my dell BIOS load i get the puprle screen and then a black screen and this at the top "[9783] Support for cores revisions 0x17 and 0x18 disabled by module... " sorry i think there's more to it and that's probably crucial but it goes SO fast sometimes and sometimes slower... I just wiped my laptop and installed 13.10 over it and ticked LVM at installation and log in automatically, idk if that would make a difference here... Any way i found someone else on Arch Linux had the same problem but I don't know how to solve it. https://bbs.archlinux.org/viewtopic.php?id=170588 Anyone know what this might be? Please help, new user..

• Xubuntu loading slow after the session/password select

  - by Bryan

  I recently installed Xubuntu on my computer. I love the distro. Everything was fast, and then the bootup slowed down. It started taking a couple minutes for my user selected wallpaper to show and the menu to appear, basically do anything on the comp. I do not recall doing anything other than changing the swappiness. It did not affect it initially. Would that be something to affect it or are there other ideas that might have caused this sudden change.

• Can't restart from Ubuntu 12.10

  - by Sankalp Kota

  I am dual-booting Ubuntu 12.10 and Windows 8 Pro. Both run seamlessly but I've had the persistent issue of not being able to restart my machine properly from Ubuntu. If I am on Ubuntu and hit the 'Restart..' option, the screen turns off and Ubuntu shuts down, but the computer never turns off and grub bootloader never shows on the screen. However, rebooting from Windows gets me to the bootloader as it should. Turning off the machine completely with 'Shut down' works fine with both Ubuntu and Windows as well. This issue was present even when I was dual booting Ubuntu 12.04 and Windows 7 Starter as well. My computer is an Acer AOD257 with 2 GB RAM, Intel Atom N570 Processor. Any help would be greatly appreciated!

• How to mount NTFS drive at startup

  - by user3403

  I'm not even sure if this is the right question, but basically I have a partition with Windows 7 on it (named Acer in my Ubuntu places menu) that I have to click on every time I start the computer in order for my music to come up in Rhythmbox, since my music is stored on the windows drive. What I want to do is have the NTFS drive "Acer" mount automatically when I start the computer, so my music is there automatically.

  In upgrading 12.04 to 12.10 via system upgrade when the system rebooted all I got was my desk-top without any command icons. Now all my files are locked into 12.10 and no way to retrieve them.

• 'mount: error while loading shared libraries: libudev.so.0 : no such file or directory' error while booting

  - by user199551

  I was trying to load a version of CGminer which was returning a libudev type error, and followed a supposed solution here but it destroyed my system (so it seems). I loaded the system in recovery mode from GRUB but all that done was actually tell me what I something is broken, do not know what to do next. I think I somehow associated a libudev.so.0 to 1 or 1 to 0, I am not sure what I did and how to fix it.

• Trouble installing Ubuntu.

  - by CV13

  I have a blank 1TB hard drive that I have run ubuntu on before. I recently formatted it and am trying to reinstall Ubuntu 12.04 LTS on there. Using the Universal USB installer and the 64-bit iso file, I booted up my computer with only my 1TB hard drive connected. I go through the installation process normally, until I restart my computer at the end. Once restarted, I start to experience the problem deal with here. When I run it normally, it goes to a black screen with a blinking cursor. When I select the "Recovery Mode" option, a bunch of lines scroll across the screen, the last of which is "hostap_pci: Registered netdevice wifi0". It then stops there with a blinking cursor. When I follow the instructions on the page I linked to (replacing "quiet splash" with "nomodeset") and bunch of lines scroll through after I press Ctrl+x. The last line displayed is Adding 8386556k swap on /dev/sda5. Priority:-1 extents:1 across: 8386556k It then stops there with a blinking cursor. How do I fix this problem?

• No partitions in Ubuntu isntallation

  - by user204212

  Today, with the new version of Ubuntu, I have decided to install it in my laptot, but running with Windows 8, which is the OS I have installed now and that I don't want to uninstall, because I need some programs. I have downloaded it and burned into a CD. Everything in the "installation" goes right untill I have to choose where to install it. It doesn't recognise my Windows 8 and, moreover, it sees my disk as it was all empty space (500Gb). I can't install it and I don't know what to do, so let's see if you can help, because you know a lot more than me in this topic :) Thanks!

• Php sessions secure log in

  - by Doodle

  My question is about creating a secure log in routine. After comparing the user name and password to the stored values I set a session variable called logged to true. Then as the user surfs around the web page I just check the logged variable for true or false to determine if the user should have access. This is my first time creating something like this. Is this secure? I feel like there is something else that I should be doing to make sure that users are valid.

• Convert ASP.NET membership system to secure password storage

  - by wrburgess

  I have a potential client that set up their website and membership system in ASP.NET 3.5. When their developer set up the system, it seems he turned off the security/hashing aspect of password storage and everything is stored in the clear. Is there a process to reinstall/change the secure password storage of ASP.NET membership without changing all of the passwords in the database? The client is worried that they'll lose their customers if they all have to go through a massive password change. I've always installed with security on by default, thus I don't know the effect of a switchover. Is there a way to convert the entire system to a secure password system without major effects on the users?

• Portable and Secure Document Repository

  - by Sivakanesh

  I'm trying to find a document manager/repository (WinXP) that can be used from a USB disk. I would like a tool that will allow you to add all documents into a single repository (or a secure file system). Ideally you would login to this portable application to add or retrieve a document and document shouldn't be accessible outside of the application. I have found an application called Benubird Pro (app is portable) that allows you to add files to a single repository, but downsides are that it is not secure and the repository is always stored on the PC and not on the USB disk. Are you able to recommend any other applications? Thanks

• How to test for secure SMTP mail service on a mail server

  - by Vinay S Shenoy

  I'm working on a project to auto-configure a user's email server settings in Java. I am extracting the mail server from his email address and looking up the MX records of that mail server using the DirContext class with com.sun.jndi.dns.DnsContextFactory. Then I'm opening a Socket to each server and testing them using a HELO command and checking the responses. My problem is that this works only when I test it with the unsecure SMTP port 25. How can I use it with the secure port 465? I tried using Secure Sockets by using SSLSocketFactory sslsocketfactory = (SSLSocketFactory)SSLSocketFactory.getDefault(); SSLSocket socket = (SSLSocket)sslsocketfactory.createSocket(mailserver, STANDARD_SMTP_PORT); But all connections get a timeout exception as follows alt1.gmail-smtp-in.l.google.com. java.net.ConnectException: Operation timed out Please help.
