  • The Loser In Our Windows vs. Linux Tests: Intel Graphics

    <b>Phoronix:</b> "We are still working on the first part of our Windows 7 vs. Ubuntu 10.04 LTS benchmarks that are set to be published early next week, but so far there is one easy conclusion to draw from the completed tests: Intel's Linux graphics driver is still no match to the Intel Windows driver."

  • Psychonauts, what to do with 'psychonauts-linux-06042012-bin'?

    - by coldcaption
    Psychonauts came in a neat file called psychonauts-linux-06042012-bin. The file system calls it an executable, but I can't find a way to execute it. Ubuntu suggested using "PyPar2" to open it like an archive, which made it into a bunch of .par2 files, but it then couldn't find anything else to open those. It seems that other people have been able to start the game, so what should I do differently?

  • Les générateurs de nombres pseudo-aléatoires de Linux ne seraient pas robustes, une récente recherche le démontre

    Les générateurs de nombres pseudo-aléatoires de Linux ne seraient pas robustes Une récente recherche le démontreLa cryptographie repose sur la génération des nombres aléatoires. Si dans la vie réelle il est facile d'observer de phénomènes aléatoires, la modélisation mathématique du hasard est quand à elle vraiment difficile.Dans le domaine de la sécurité informatique on utilise plutôt les nombres pseudo-aléatoires. Cette appellation est justifiée du fait que ces nombres sont générés par un algorithme...

  • Samsung crée F2FS, un nouveau système de fichiers open source pour mémoire Flash qui sera intégré au noyau Linux

    Samsung crée F2FS son nouveau système de fichiers open source pour mémoire flash qui sera intégré au noyau Linux Samsung a mis au point un nouveau système de fichiers destiné aux supports de stockage flash. Les systèmes de fichiers anciens qui sont actuellement utilisés pour le stockage sur les mémoires flash NAND très répandues sur les terminaux mobiles présentent des limites assez importantes. Certains constructeurs de smartphones comme RIM ou encore Sharp ont été obligés de se tourner vers le système de fichiers propriétaire Extended File Allocation Table (exFAT) de Microsoft contre payement de redevances.

  • Active directory authentication for Ubuntu Linux login and cifs mounting home directories...

    - by Jamie
    I've configured my Ubuntu 10.04 Server LTS Beta 2 residing on a windows network to authenticate logins using active directory, then mount a windows share to serve as there home directory. Here is what I did starting from the initial installation of Ubuntu. Download and install Ubuntu Server 10.04 LTS Beta 2 Get updates # sudo apt-get update && sudo apt-get upgrade Install an SSH server (sshd) # sudo apt-get install openssh-server Some would argue that you should "lock sshd down" by disabling root logins. I figure if your smart enough to hack an ssh session for a root password, you're probably not going to be thwarted by the addition of PermitRootLogin no in the /etc/ssh/sshd_config file. If your paranoid or not simply not convinced then edit the file or give the following a spin: # (grep PermitRootLogin /etc/ssh/sshd_conifg && sudo sed -ri 's/PermitRootLogin ).+/\1no/' /etc/ssh/sshd_conifg) || echo "PermitRootLogin not found. Add it manually." Install required packages # sudo apt-get install winbind samba smbfs smbclient ntp krb5-user Do some basic networking housecleaning in preparation for the specific package configurations to come. Determine your windows domain name, DNS server name, and IP address for the active directory server (for samba). For conveniance I set environment variables for the windows domain and DNS server. For me it was (my AD IP address was 192.168.20.11): # WINDOMAIN=mydomain.local && WINDNS=srv1.$WINDOMAIN If you want to figure out what your domain and DNS server is (I was contractor and didn't know the network) check out this helpful reference. The authentication and file sharing processes for the Windows and Linux boxes need to have their clocks agree. Do this with an NTP service, and on the server version of Ubuntu the NTP service comes installed and preconfigured. The network I was joining had the DNS server serving up the NTP service too. # sudo sed -ri "s/^(server[ \t]).+/\1$WINDNS/" /etc/ntp.conf Restart the NTP daemon # sudo /etc/init.d/ntp restart We need to christen the Linux box on the new network, this is done by editing the host file (replace the DNS of with the FQDN of the windows DNS): # sudo sed -ri "s/^(127\.0\.0\.1[ \t]).*/\1$(hostname).$WINDOMAIN localhost $(hostname)/" /etc/hosts Kerberos configuration. The instructions that follow here aren't to be taken literally: the values for MYDOMAIN.LOCAL and srv1.mydomain.local need to be replaced with what's appropriate for your network when you edit the files. Edit the (previously installed above) /etc/krb5.conf file. Find the [libdefaults] section and change (or add) the key value pair (and it is in UPPERCASE WHERE IT NEEDS TO BE): [libdefaults] default_realm = MYDOMAIN.LOCAL Add the following to the [realms] section of the file: MYDOMAIN.LOCAL = { kdc = srv1.mydomain.local admin_server = srv1.mydomain.local default_domain = MYDOMAIN.LOCAL } Add the following to the [domain_realm] section of the file: .mydomain.local = MYDOMAIN.LOCAL mydomain.local = MYDOMAIN.LOCAL Conmfigure samba. When it's all said done, I don't know where SAMBA fits in ... I used cifs to mount the windows shares ... regardless, my system works and this is how I did it. Replace /etc/samba/smb.conf (remember I was working from a clean distro of Ubuntu, so I wasn't worried about breaking anything): [global] security = ads realm = MYDOMAIN.LOCAL password server = 192.168.20.11 workgroup = MYDOMAIN idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes client ntlmv2 auth = yes encrypt passwords = yes winbind use default domain = yes restrict anonymous = 2 Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start Setup the authentication. Edit the /etc/nsswitch.conf. Here are the contents of mine: passwd: compat winbind group: compat winbind shadow: compat winbind hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files Start and stop various services. # sudo /etc/init.d/winbind stop # sudo service smbd restart # sudo /etc/init.d/winbind start At this point I could login, home directories didn't exist, but I could login. Later I'll come back and add how I got the cifs automounting to work. Numerous resources were considered so I could figure this out. Here is a short list (a number of these links point to mine own questions on the topic): Samba Kerberos Active Directory WinBind Mounting Linux user home directories on CIFS server Authenticating OpenBSD against Active Directory How to use Active Directory to authenticate linux users Mounting windows shares with Active Directory permissions Using Active Directory authentication with Samba on Ubuntu 9.10 server 64bit How practical is to authenticate a Linux server against AD?

  • mac osx active directory authentication and linux samba share problems.

    - by Matt Delves
    As a precursor, the network setup is one that includes a combination of Novell Netware servers as well as Windows Servers and Linux servers. I've successfully been able to bind my mac to the Windows Domain and can login without any problems. I've been able to mount shares without needing to resupply login credentials to any windows based share. The problem I've found is that when I'm attempting to mount a share from a linux server, it is asking to resupply the login credentials. Has anyone experienced this kind of problem. The linux servers are a combination of SLES 10 and 11 and RHEL 4 and 5. Thanks, Matt

  • Renting linux server just to make backups of my personnal data ?

    - by Matthieu
    Hi all, I would like to be able to backup ALL my computers data on a Linux server. For now, I have a home server, but soon I will be travelling, without home (so no home server). I was thinking of renting a dedicated linux webserver, but this is expensive, and I don't need a fast machine "web-oriented" with mysql server and all, I just need a full SSH access (full control, and then I install my programs). Does "backup servers" exist ? Am I doing it wrong (maybe that is not a good solution) ? Note : I run Mac OS, Windows and Linux, I backup through rsync, I want full control on my backup, not an automated "magic" backup like MobileMe or anything like that. Edit : I need around 500Gb storage

  • How to use windows desktop from a linux machine in a local network?

    - by Hristo Hristov
    I have a computer running Windows 7 with no monitor or keyboard, connected to a local network. I have a few laptops running linux, also connected to the local network. I want to feel like I'm sitting in front of the windows, but using one of the linux laptops. How to do that? Maybe I can use some linux software to connect to remote desktop? Or I have to install client/server software on both machines? As this is a local network, I expect excellent experience with no lag. Thank you!

  • I am trying to setup phpMyAdmin to use with a remote MySQL databases on Scientific Linux release 6.2

    - by techsjs2012
    I am trying to setup phpMyAdmin to use with a remote MySQL databases on Scientific Linux release 6.2. If I use the mysql command line to connect to the remote database it works great but if I use mysqladmin I am getting "#2002 Cannot log in to the MySQL server". I have found if I do a: setenforce 0 It will work from myphpadmin to my remote database but once I reboot or set Scientific Linux setenforce back to one it stops working again.. I know setenforce 0 is not the right thing to do but can someone please give me details steps on how to get this working the right way... thanks I am new to Scientific Linux and been having some issues.. thanks

  • Can I install fresh Linux accross partitions (LUKS & LVM) and preserve/use existing home user?

    - by xtian
    With an existing LUKS encrypted logical volume partitioned hard disk dual boot to Windoz and Linux (Fedora 15), is it necessary to "start over" with the LUKS setup when upgrading the system? I recall some note about dividing the Linux installation over different partitions would help to preserve the home data in future update (I can't find this now) Before I try it, is this possible and intended use case for partitioning a Linux installation? # lsblk -fa NAME FSTYPE LABEL MOUNTPOINT sda [80G] +-sda1 [system W95 FAT 32] vfat +-sda2 ext4 /boot +-sda3 [52.4G] crypto_LUKS +-luks-de25ac97-6a32-4b79-a6a0-296a39376b3b (dm-0) LVM2_member +-cryptVG-root (dm-1) [21.5G] ext4 / +-cryptVG-swap (dm-2) [5.4MB] swap [SWAP] +-cryptVG-data (dm-3) [25.6G] ext4 /home

  • My Mother Bought a Droid

    - by Ben Griswold
    I converted to iPhone two years ago when I left my former employer and my Blackberry behind. The truth is I half-heartedly purchased my iPhone. It was a great looking device, but as far as I was concerned, it was a mere toy compared to my Blackberry.  I remember hiding the toy in my briefcase when attending business meetings because I didn’t consider it to be professional enough.  I’ve since owned all three generations of the iPhone and, well, iPhone seems to have caught on. I still miss the click of the Blackberry keyboard and the blinking red light letting me know that someone/something requires my attention, but I’m officially an iPhone fanboy now.  My mom called last weekend and asked if she should buy an iPhone. I talked her ear off about everything I love about iPhone. I went on for about twenty minutes. I couldn’t help myself. I mentioned everything from my podcast subscriptions to the application which manages my workouts.  I went as far as to say that someday all smart phones will be referred to as iPhones just like all tissues are referred to as Kleenex and all sodas are referred to as Cokes.  I was really on a roll and then I stopped. I had to…the call dropped.  There I was, strategically standing in the far corner of my backyard where I get the most reliable AT&T reception and the call drops in middle of my iPhone pitch.  Folks, I don’t care how good a salesperson you are, it’s tough to recover from a situation like this.   I dialed my mom back and jokingly asked if she was planning to make calls with her new phone. I explained that AT&T is bound to provide better service eventually but I’m not sure she should wait. After all, I have troubles with the network in San Diego and I can only image how bad it would be for her in Western Massachusetts. Mom called back a few days later exclaiming, “I bought a Droid! I love this phone! I haven’t done anything with it but make phone calls, but I love it.”  I had to laugh.  My mom made the right call (pun intended.)  The iPhone is an amazing device, but owners are constantly reminded that its core function (it’s a phone, remember?) is subpar.  If you love gadgets, you’re probably enthralled by iPhone’s many bells and whistles and, relatively speaking, the terrible phone service might not amount to much.  (Maybe it amounts to a rant on your blog.) The overall iPhone offering is so attractive that consumers are willing to wait for AT&T to straighten up their act or wait until Apple grants a choice of carriers.  But I don’t see either of these remedies coming soon. In the interim, I’m willing to take my iPhone for what it is and just continue to enjoy my favorite features while pretending that poor coverage isn’t a big deal. With any luck, more and more reasonable folks will recognize that Android Phones are legitimate players in the smart phone space, they will buy loads of them and there will become plenty of functional phones to borrow when my “phone” is showing zero bars.  Heck, I’m already covered when I visit my mom.
