• Sync KeePassX with KeePass2

  - by bioShark

  Simply put: In Ubuntu I am using KeePassX and in Windows KeePass2. In am not able to export/import passwords from one to another. I would prefer to use the same database, but I don't really know how. If there is no possibility to sync the 2, can you recommend another password vault, which is able to sync passwords from 2 OS, using a shared DB. Thanks I am using Ubuntu 12.04 and Win 7. Edit: I have noticed that KeePass2 is available in the Software Center, so I have installed it, and I can successfully open my Win7 database. Now I will migrate my KeePassX passwords. I am seeing now a huge difference in the looks. While KeePassX doesn't exactly have Ubuntu like look&feel, it's 100 times more elegant than the interface KeePass2 comes with. Well, maybe that was my initial decision for installing KeePassX on my Ubuntu machine. I can't remember. @fossfreedom, please add your comment as a response, so that I can accept it. Thank for the suggestion

• please help me understand libraries/includes

  - by fiftyeight

  I'm trying to understand how libraries work. for example I downloaded a tarball and extracted it. Now I do "./configure", it searches in pre-defined directories from what I understand for certain library files. What does it do then? it creates a makefile, and the makefile contains the paths to these libraries? than I do "make", it complies the source code and hard-codes the locations of the libraries? am I correct? I do not really understand if libraries are files with pre-defined paths or the OS somehow gives access to the libraries through system calls. another example, I complied something on my computer than moved it to a remote server, the executable needs mysql libraries to work, the server has mysql but for some reason when execute the file it tells me "can't find libmysqlclient.so.16". is there a solution for this? is there a way to know where is tries to locate this file or give it another path? I can't compile it on the server since it has no compiler and I don't have root access to install packages last question is if in the sequence "./configure","make","make install" the "make install" command is the only one that actually puts files outside the directory in which these files reside? if for example the software will be installed in /usr/local/ is the "make install" command the only one that will require "sudo" before it? let me see if I got it correctly: "./configure" creates the Makefile according to the location of various files on your system. "make" compiles the source code according to this makefile. and "make install" moves the files to their appropriate location. I know this has been very long I thank anyone who had the patience to read my question :)

• Why is my root filesystem always scanned at boot?

  - by luri

  I always have a pause at boot saying my filesystems are being checked (with a "press C to cancel" note, too). Actually (seeing boot.log) I think it's the / fs, which is located at /dev/sdb5 Several questions altoghether, here (hope this does not break any rule): Is this normal? Can I (or even should I) prevent this anyhow? According to boot.log (below) the fs does not seem to be 'clean', or, at least, it's in an state or condition that makes fsck always can it for errors for a while (just a few seconds). How can I fix it? Edit: This is my boot.log: fsck desde util-linux-ng 2.17.2 udevd[515]: can not read '/etc/udev/rules.d/z80_user.rules' /dev/sdb5: 249045/32841728 ficheros (0.3% no contiguos), 20488485/131338752 bloques init: ureadahead-other main process (1111) terminated with status 4 init: ureadahead-other main process (1116) terminated with status 4 Password: * Starting AppArmor profiles [160G Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox [154G[ OK ] * Setting sensors limits [160G [154G[ OK ] And this is dumpe2fs results for the filesystem being checked (well, the relevant part of the log): Filesystem volume name: <none> Last mounted on: / Filesystem UUID: 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 32841728 Block count: 131338752 Reserved block count: 6566937 Free blocks: 110850356 Free inodes: 32592701 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 992 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Fri Dec 10 19:44:15 2010 Last mount time: Mon Feb 14 17:00:02 2011 Last write time: Mon Feb 14 16:59:45 2011 Mount count: 1 Maximum mount count: 33 Last checked: Mon Feb 14 16:59:45 2011 Check interval: 15552000 (6 months) Next check after: Sat Aug 13 17:59:45 2011 Lifetime writes: 331 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 First orphan inode: 28049496 Default directory hash: half_md4 Directory Hash Seed: d3d24459-514b-4413-b840-e970b766095b Journal backup: inode blocks Journal features: journal_incompat_revoke Tamaño de fichero de transacciones: 128M Journal length: 32768 Journal sequence: 0x0005e0c4 Journal start: 1 This is the relevant (at least I think this is the fs being checked) line in fstab: #Entry for /dev/sdb5 : UUID=42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 / ext4 errors=remount-ro 0 1

• Which is generally considered faster or best practice: symlinks or Apache aliases?

  - by Christopher W. Allen-Poole

  I'm curious as to what most people's views are on this subject. Personally, I will almost always prefer symlinks unless I have no other option -- I find that it is far more obvious when someone is navigating the file system, but, on the other hand aliasing is more platform independent. Windows XP, for example, doesn't have anything remotely comparable to symlinks (NTFS junctions are not interpreted correctly by at least some environments), which means that anything which relies on symlinks in a *nix based system cannot be transferred. (I know that Windows 64x OS's have symlinks, but I've not seen if they can be read correctly by the environments previously mentioned) In addition to this, I was also wondering which is considered faster. Is this even possible to know? Do you have a conjecture? I would imagine that since symlinks are generally more low-level than Apache it would make sense that they would be referenced faster, but, on the other hand, I would guess that Apache is required to do a lookup in either case so it would be disk read dependent.

• How to securely delete files stored on a SSD?

  - by Chris Neuroth

  From a (very long, but definitely worth to read) article on SSDs: When you delete a file in your OS, there is no reaction from either a hard drive or SSD. It isn’t until you overwrite the sector (on a hard drive) or page (on a SSD) that you actually lose the data. File recovery programs use this property to their advantage and that’s how they help you recover deleted files. The key distinction between HDDs and SSDs however is what happens when you overwrite a file. While a HDD can simply write the new data to the same sector, a SSD will allocate a new (or previously used) page for the overwritten data. The page that contains the now invalid data will simply be marked as invalid and at some point it’ll get erased. So, what would be the best way to securely erase files stored on a SSD? Overwriting with random data as we are used to from hard disks (e.g. using the "shred" utility) won't work unless you overwrite the WHOLE drive...

  I just bought this notebook and I've already installed in a new partition Ubuntu 12.04 LTS with 6gb of swap memory. UPDATE2: This is the laptop configuration: http://h10025.www1.hp.com/ewfrf/wc/document?cc=it&lc=it&dlc=it&tmp_geoLoc=true&docname=c03397517 Sometimes (without any special conditions) Ubuntu freezes. My mouse is blocked, the UI is blocked, ALT+F1 to kill something or to restart is blocked, I can't really do anything... I've also tried and it freezes with: Ubuntu 3D Ubuntu 2D Gnome Shell and it freezes both with low and high load. I can only press on power button (physically) and restart my laptop (and this is not the correct way to do things). I'm using this laptop for work, so I need a stable OS without this freeze. Someone knows how to solve this problem?

  - by Entity_Razer

  What i'm trying to do is install Xen in a test environment, now I am trying to run the: apt-get build-dep xen-3.3 command, but it keep throwing a error which literally translated from dutch (installed the debian OS in Dutch) say's: E: your sourcelist (/etc/apt/sources.list) has to contain at least 1 source-URI I've googled it but I can't seem to find a definitive solid answer on how to fix this. By default a source-URI (read man page of apt-get) states it needs to be something along the lines of deb ftp://ftp.debian.org/debian stable contrib Now I've got 2 HTTP sources (default Debian ones) up & running so far and they've been working flawlessly for the better part of a few days now. Only now its starting to act up. Anyone able to help me out ? Much obliged !

• Importing Outlook 2007 rules error

  - by Alex

  I'm trying to move an Outlook 2007 account (POP3, no Exchange) to a new machine and I'm having trouble importing the rules from the old machine to the new one. Here is the deal, I imported the .pst file on the new machine but when I try to import the rules, every single one of them brakes. The folders and sub-folders hierarchy is preserved upon the import of the .pst but the rules don't point to the right folder in the respective rule. Instead it points to "the specified folder". Same OS (Windows XP), same mail client (Outlook 2007) and the .psf file is about 8 GB. Any help i greatly appreciated.

• How hard for a Software Developer to Maintain a Server

  - by Samy

  I'm a software developer and don't have much experience as a sysadmin. I developed a web app and was considering buying a server and hosting the web app on it. Is this a huge undertaking for a web developer? What's the level of difficulty of maintaining a server and keeping up with the latest security patches and all that kind of fun stuff. I'm a single user, and not planning to sell the service to others. Can someone also recommend an OS for my case, and maybe some good learning resources that's concise and not too overwhelming.

• Keyboard freezes / stuck if a key pressed repeatedly

  - by Aziz Rahmad

  I use Acer 4530. This problem has happened long since Ubuntu 10.10 and now that I use 11.04 dual booted with Linux Mint 10. Everytime I press one key repeatedly, like when I read a long article in a website/ebook or when I play games which required me to press arrow keys repeatedly, it would randomly freeze. That is, whatever I press on keyboard has no effect, and that also happens with touchpad. However, the USB mouse works just fine. I later found out that it's not actually freeze but more like it's like the key stuck. For example when I play tetris which I usually press w (down) button repeatedly, after some times it would freeze. And if I put the cursor in, say, browser's address bar, it would type "wwww....." infinitely. The only way I could fix it is by suspend the laptop, either by using mouse or by closing the lid. And instead of suspended, in that case the laptop would automatically wake up and everything will be fine. (Usually my laptop would wake up after suspended by pressing any key) It has happened since the first time I use Ubuntu, 10.10, and it also happens in Linux Mint 10, and until now in Ubuntu 11.04. It never happened when I use Windows, though. Anyone has ever encounter similar problem? Anyone know how to fix it permanently? UPDATE I just recently installed Windows 7 and Windows 8 Development Preview and both have similar symptoms. So I declare that this problem is not OS specific, probably hardware problem.

• How to configure 2nd network card for use in VMWare Workstation?

  - by Timo

  Hi all, I am using VMWare Workstation 6.5, connected to my network with a bridged adapter so that the virtual machine OS (Windows XP) has its own IP adress. This just worked out of the box. Now my host machine (Windows Vista) has an additional network card that is directly connected to another computer using a crossover cable (and fixed IP adress 10.1.1.4, while the "main" network connection is using DHCP with IP in the 192.68.0.* range). How can I use that network connection as well in the virtual machine? Do I need to bridge my 2nd network adapter to some VMnetX adapter? Do I need to add a host virtual adapter? I do not know much about networks, and the VMWare network settings really confuse me :-) Thanks, Timo

• Authenticating a Windows client to a Samba share

  - by hekevintran

  I have a Samba network share being served by a Linux machine. The share is read-only unless you give it a username and password. I want my Windows 7 client machine to connect to it. It appears that the Windows machine is connecting as a guest because it does not have write access. The Windows machine never asks me whether or not it should connect as a guest or with a username. How do I make the Windows machine authenticate? Where do I input my password? This seems like such a simple thing yet I am totally confused. On Mac OS and Linux, it simply asks you for a username.

  I use the open source application UliPad to edit restructured text files (rst). It is a Python application that I launch via Terminal like so: python32 UliPad.py I have python32 as an alias to the 32bit install of Python on my machine. I have several versions installed. First I would like a way to launch UliPad like other OS X apps. Not really sure how to do this. Secondly, I would like to set all .rst files to be opened with UliPad.py. Is there a way to do this? I know how to choose the default app in Finder but not sure how to choose UliPad as that app.

• Brother MFC-J470DW scan function "Check Connection"

  - by user292599

  I have a Brother MFC-J470DW printer that I have connected to a Linux desktop (running Ubuntu 14.04) using a wireless router network. The printer works fine for printing and copying, but now I want to add the scan function. To set up the scan function, I went to the Brother web page for this printer: http://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&lang=en&prod=mfcj470dw_us_eu_as&os=128 and under Scanner Drivers selected "Scanner driver 64bit (deb package)", "Scan-key-tool 64bit (deb package)", and "Scanner Setting file (deb package)". For each package, I clicked the EULA, and selected "open with Ubuntu Software Center". Then after the USC window pops up, I click on Install and the red line goes from left to right. In each case, the USC window then had a green checkmark and the Install box changes to Reinstall (that's how you know it worked). So now I try it out. Hitting the Scan button on the printer, selecting "Scan to file", and hitting ok produces the message "Check Connection". I checked the Brother Linux Information FAQ (scanner) page and the 14th question seems the same as mine: When I try to use the scan key on my network connected machine, I receive the error "Check connection" or I can not select anything except "scan to FTP". I explored the solution given for this FAQ, but found from ifconfig that I am already using eth0, the default setting, so presumably that is not the problem. I also found brscan-skey installed in /usr/bin and did drrm@drrmlinux2:~$ brscan-skey -t drrm@drrmlinux2:~$ brscan-skey but that didn't help - I still get the "Check connection" message. What can you suggest to fix this problem?

• WiFi can't reconnect after suspend/hibernate on Ubuntu 12.04.1

  - by CyberOPS

  I've had this problem since Ubuntu 11.10 (my first install) but I was able to get around this issue with this answer. When I updated to Ubuntu 12.04 I encrypted the home folder, so I wasn't able to suspend or hibernate anymore (disappointing :l). Because of this and another issue I had1, I chose to reinstall. Sometime after I reinstalled, I was reminded about reconnection issue because it wasn't working after I suspended. I tried to use the same fix as before but I couldn't get it to work. I've also tried a couple other different fixes I found around the web but they didn't work. Since I'm new to linux, I'm gonna have a tough time figuring this out by myself. So does anyone know how, or what I need to figure out how, to fix this? Info: Computer: HP Pavilion dv6t-6b00 CTO Quad Edition Entertainment Notebook PC Network Card: Intel® Centrino® Wireless-N 1000 OS: Ubuntu 12.04.1 (x64) dual booting with Windows 7 (x64) (Not using Wubi) Wireless Card Driver: Intel Wireless WiFi Link drivers for Linux (iwlwifi) 1 - ntfs-config caused colord to crash on startup, even after NTFS-Config was removed.

• Remotely connecting to a Hyper-V hosted VM's console.

  - by billpg

  Hi everyone. I've just managed to successfully move an aging beige box into a Hyper-V virtual machine. We used to use the beige box by walking over and sitting at the computer itself, but we can't do that so easily when its inside the Hyper-V system. Is there a way please to access the VM's console from a workstation running XP Pro? Please note that its an obscure OS running inside the VM, so installing a VNC or similar service inside the VM is not an option. Many thanks.

• HP ProLiant DL320e G8 v2 - USB2.0 during POST

  - by user3513346

  Initially my USB2.0 ports were working during POST (and boot). However, now they appear not to be. I first noticed this when I could not access the RBSU by pressing F9 during POST. Then found that I couldn't boot from USB either (I was able to do both of these initially). When performing the boot via iLo remote console I can access all of the setups (i.e., all of the F(X)'s) and can boot virtual media from a 'removable drive'. Keyboard works fine once the OS is booted. Not really sure what to try here. Any advice would be greatly appreciated. Thanks. Nick.

• Boot Camp fails to create a Windows partition because it can't move files

  - by Jens Bannmann

  I'm running Mac OS X 10.6 (Snow Leopard) on a mac with a 320 GB drive, 167GB free space, and I can't get Boot Camp running. The wizard starts creating the Windows partition, but fails with a message claiming it cannot move some files. The message suggests to back up my hard disk, reformat it, restore my files, and re-run Boot Camp wizard. The problem is: Though I do have backups (Time Machine), I don't feel like formatting my hard disk right now :-) I found a thread in some forum discussing this problem. The suggestion was to defragment my volume with iDefrag, and lots of people claimed that solved the issue. So I went ahead and got iDefrag 1.7.1, created a bootable DVD and chose the "compact" setting recommended before partitioning - but still no luck with Boot Camp! So how do I get this working? Fun note: last year, I briefly set up Boot Camp with 10.5, and it worked perfectly. Probably I did not use that much hard disk space back then...

• New Oracle Solaris 11 Administration book

  - by glynn

  During the development of Oracle Solaris 11, one of the main goals was to modernize the operating system and remove some of the existing frustrations that our administrative audience had in deploying and using the platform within data centers around the world. That meant a comprehensive clean out of some existing technologies to provision the operating system (replacing Jumpstart with Automated Installer) and manage system software (replacing SVR4 with IPS packaging), consolidate the vast spectrum of networking configuration, and enhance the user environment to provide familiarity for those who were used to administering Linux environments among many other things. While some considered the changes to Oracle Solaris 11 as a negative change, most will be impressed at how far we've come - the deeper integration of key technologies, presented in a consolidated and consistent form. It is easier to administer the Oracle Solaris platform that ever before, and I have no doubt that administrators coming from other platforms will be hugely impressed with what they see, especially if they're judging based on past experiences of Solaris 8 and Solaris 9. In fact I'd go further to say that Oracle Solaris 11 is a more powerful, integrated and usable platform that most Linux platforms I've seen. But as with anything, there's always an initial learning curve to get through. We've provided a significant selection of learning materials out on the Oracle Solaris 11 pages on Oracle Technology Network and some great training and certification options. One more option is now available in the form of a book, the Oracle Solaris 11 System Administration The Complete Reference. This provides an exceptional reference to help administrators learn about Oracle Solaris 11, especially those who have come from the Linux platform. As is quoted in the first chapter of the guide: Linux users and developers will find in Oracle Solaris 11 a familiar and quickly productive working environment; we point out similarities and differences between the Linux and Solaris kernels and system administration tools, and describe how typical open source Web development tasks are accomplished in this OS. So I would encourage you to take a read of it and start seriously considering Oracle Solaris 11 to be a platform choice for your data center. Oracle Solaris 11 System Administration The Complete Reference - yours for only $32.50 (if you successfully use the promotion code - otherwise worth shopping around to pick up a good deal).

• Driver for writing to UDF partitions from Windows XP?

  - by davr

  I'm considering using an UDF partition to share data between Windows XP, 7, and Linux. It's more efficient than FAT32, and avoids the 4GB max file size limit. I've found it will also work with Mac OS X, more details in this questions. However, in Windows XP, it is read-only. I'd like to write to it too. Are there any drivers that will allow this? I've found a few that support writing UDF...but they are designed for writing to CDs or DVDs, not specifically for HDDs or USB Flash drives: DLA, InCD, Drag-To-Disc. Will any of those 3 drivers work for HDDs/USB Flash drives? Or is there another driver that will do what I want? Thanks.

• Disabling at application level a nic (network interface) on Windows

  - by Leandro

  How can I disable at application level a network interface? The main question is this: If I disable the nic trough wmic (win7) or devcon (XP), the "plug and play" of a wired nic doesn't work any more. For example, if the user put the cable on a disabled nic, the OS doesn't know about it. So I need to persist the enable condition but disabling the networking like a disable nic. There's some API, network configuration (routing, changing ip, changing gateway, any), .NET Framework resource (Only NetFramework 2.0) or do you can think in any workaround to do this? Suggest and ideas also will be treated as a solution. Thanks and kind regards.

• How does the build quality of laptops compare?

  - by pgwillia

  I'm looking to replace my 5 year old laptop. I want my next laptop to endure at least this long. I typically have Thunderbird, Firefox, Eclipse Java IDE, Skype, a ssh session, and Apache Tomcat running. I'm currently running Karmic Ubuntu, but am agnostic about operating system and would move to Win 7 or OS X. I frequently travel with this computer. I also value battery longevity and power conservation (if possible). Above all I'm looking to minimize cost. I think the hardware that best meets my needs is an Intel i7 processor, 8 GB RAM, 100GB @7200 rpm or SSD hardrive, and about 15 inch monitor. These specs are met by most brands. Does anyone know specific pros/cons and build quality for Macbook Pro, Lenovo Thinkpad (W510 or T510), Sony's VPC-F1190, and ASUS G Series G73JH-X1 NoteBook? Are all i7 processors created equal? Do you have other suggestion that meet my needs?

• Password manager solution: Symbian based phone and a Linux machine (Windows is not important, but wo

  - by Kent

  Hi, I currently use KeePassX to manage my passwords on my Linux (Xubuntu) machine. It's nice to have all the passwords encrypted, but sometimes I'd like to be able to tell a password when I'm on the run. Therefore I'm looking for a solution which I can synchronize with my phone. I have a Nokia N82 which is a Symbian OS v9.2 based phone for the S60 3rd Edition platform with Feature Pack 1. I like an open source solution if it's possible. In case it isn't I wouldn't mind paying for a good solution. If Windows may be added to the synchronization mix it's nice, but it's absolutely not a primary requirement (I don't even have any computer running Windows).
