• Application to store/browse/view photos?

  - by amorfis

  I am looking for application which I can install on Ubuntu server and put my photos there. It can be by web interface, it can be by mounted samba disk. What I require: Ability to add tags to photos. Ability to move photos. I.e. if I set photos directory to /home/photos, but then I want to move all photos to e.g. /home/common/photos - I don't want to lose all the tags. I used to use FSpot and it was great, but it lacked point 2, and I lost everything :(

• Why is systemd not setting my system time?

  - by Alex Chamberlain

  I'm running Arch Linux. Recently, when I turn on my PC, the system time is set to 1:00 1 January 1970 - presumably the 1:00 o'clock is from the timezone shift. Does anyone have any ideas why systemd isn't setting my system time correctly? Some useful output (I think)... [root@alex-desktop network.d]# timedatectl status Local time: Sun 2013-06-09 16:33:04 BST Universal time: Sun 2013-06-09 15:33:04 UTC RTC time: Sun 2013-06-09 15:18:50 Timezone: Europe/London (BST, +0100) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: yes Last DST change: DST began at Sun 2013-03-31 00:59:59 GMT Sun 2013-03-31 02:00:00 BST Next DST change: DST ends (the clock jumps one hour backwards) at Sun 2013-10-27 01:59:59 BST Sun 2013-10-27 01:00:00 GMT

• Oracle Keeps Growing Partner Certifications with Addition of McAfee

  - by Ted Davis

  Viruses stink. Whether it’s the common cold virus, Goatpox virus – yes it exists -- or a computer virus, you name it, viruses stink. When it comes to our computer server infrastructure we all want to make sure our servers are secure from any malware out there. Additionally, installation of anti-virus software is a requirement by many governments and for many enterprises both large and small. Because of the growth of Oracle Linux in their customer base, McAfee recently certified their “McAfee VirusScan Enterprise for Linux” on Oracle Linux.  It delivers always-on, real-time anti-virus protection for Linux environments. Its unique, Linux-based on-access scanner constantly monitors the system for potential attacks. While there have been few viruses found on Linux, you can now feel secure running Oracle Linux in your infrastructure with McAfee on top. We are happy to introduce McAfee into the Oracle Linux family of certified applications.

• Input not supported message when monitor is powered off then back on

  - by Jason Down

  I've been getting a message on my monitor where "Input not supported" is floating around. This only happens when I manually turn the monitor off and then later turn it back on. Leaving the monitor on and allowing it to go to the screen saver doesn't seem to cause the issue (but I prefer to turn the monitor off if I'm going to be away from the computer for any length of time). Any ideas what might cause this, only when the monitor is turned off manually? Specs: Acer X203w mointor Radeon 9600 Pro Video card Linux Mint 8 Resolution 1680 x 1050 (16:10 - Preferred native resolution for the monitor) Refresh Rate 60hz Here is what is in my xorg.conf file: Section "Device" Identifier "Radeon 9600" Driver "ati" BusID "PCI:1:0:0" Option "XAANoOffscreenPixmaps" Option "AccelMethod" "XAA" EndSection Section "Screen" Identifier "Default Screen" Device "Radeon 9600" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1680x1050" "1440x900" "1024x768" EndSubSection EndSection Section "DRI" Mode 0666 EndSection Section "Extensions" Option "Composite" "Enable" EndSection

• How to do a hexdump of first track of HDD?

  - by Daniel Gratz

  How would i do a hexdump in Ubuntu for the first track of a HDD? I am looking for a winhex-esque output if that makes sense. The first track has 63 sectors, each 512 bytes long. I tried dd if=/dev/sda bs=1 count=512 | hexdump -C but that only gave me what appears to be the MBR, or first sector of the HDD. I guess i am confused about what bs and count should be. Bs means how many bytes to display and count is how many multiples of bs? Thanks!

Any suggestions are greatly appreciated.

• buggy mouse click after a while

  - by sputnick

  The cursor of my mouse is moving as well on my twin view, but after a WHILE, or if I start kde with runlevels (I don't know why, but startx works better) I can't click anything. I have had replaced the mouse with another one, but it's the same problem, so it's not a hardware problem. The problem occurs both with gnome and kde. My config : PC Dell Optiplex 780 archlinux x86_64 (up to date) xf86-input-evdev 2.6.0-4 xorg-server 1.11.2-2 kernel linux-3.1.1-1-ARCH My Xorg log doesn't contains "EE" string for errors. Any clue ?

• Configuring Mail Relay

  - by ServerChecker

  I'm running Ubuntu Server 9.10 with Postfix and Webmin. I have created virtual hosts for 3 domains following this serverfault.com answer. But the mail isn't relaying out to the world. I have 3 domains tied into my DNS in webmin, as well as inside DNS clicked Mail Server and followed that instruction using this article on the web. The domains and the web servers work just fine. I also have FTP working just fine. So, the remaining problem I have is mail. Can't forward mail out to a Gmail account for some reason. Note I'm just trying to do the "easy version" of Postfix config and if your answer is in Webmin-ease, that would help me. However, I can edit a text file if you suggest.

  - by Matthew

  I currently have two ubuntu servers running Heartbeat and DRBD. Let's say one node is down... The servers are directory connected with a 1000Mbps cross over cable on eth1 and have access to a IP camera LAN on eth0 The node that is still functioning won't start up heartbeat and provide access to the drbd resource. I have to manually restart heartbeat by "sudo service heartbeat restart" to get everything up and running. How can I get it to start fine from a cold start? Here is the my ha.cf and some material from the syslog... If I'm missing any information that might be of some help. http://pastebin.com/rGvzVSUq <--- Syslog http://pastebin.com/VqpaPSb5 <--- ha.cf

• Gnuplot with octave produces only entirely black bar diagrams

  - by Lambda Dusk

  My problem is the following: On my system (Linux Mint 14), the normal octave and gnuplot packages only produce completely black bar diagrams: I have tried to change the colours in any way I could imagine, but no avail: bar(xbin, yy, 'barwidth', 1, 'facecolor', 'r', 'edgecolor', 'b'); xlabel('x_i'); ylabel('p_i'); print -deps bars.eps However, when I plot the graph with the command graphics_toolkit fltk; It looks fine - but fltk doesn't either understand umlauts or LaTeX-style formula notation like p_i (necessary for captions and labels). Maybe I haven't configured something correctly. I just installed octave from the repos and thought it would work. Anyone can help?

• Can I create an SSH user which can access only certain directory?

  - by RiMMER

  I have a Virtual Private Server which I can connect to using SSH with my root account, being able to execute any linux command and access all the disk area, obviously. I would like to create another user account, which would be able to access this server using SSH too, but only to a certain directory, for example /var/www/example.com/ For example, imagine this user has a HUGE error.log file (500 MB) located in /var/www/example.com/logs/error.log When accessing this file using FTP, this user needs to download 500 MB to view the last lines of the log, but I'd like him to be able to execute something like this: tail error.log Therefore I need him to be able to access the server using SSH, but I don't want to grant him access to all server areas. How can I do this?

• Other users on my Server?

  - by Jennifer Weinberg

  I'm buying a Server from a person (that I don't know really well) and I want to make sure that the previous owner hasn't got any access anymore. It's an Ubuntu Virtual Server and I already received the admin access (via shell). How can I find out if there are still other accounts left, who are still able to access my server (e.g. with a still existing shell account, ftp or another type of user account)? And how can I delete them if these accounts exist? Best regards, Jennifer

• How to increase max FD limit for a daemon process running under a headless user?

  - by Ameliorator

  To increase the FD limit for a daemon process running under a headless user on a Ubuntu Linux machine we did following changes in /etc/security/limits.conf soft nofile 10000 hard nofile 10000 We also added session required pam_limits.so in /etc/pam.d/login. The changes got reflected for all the users who logged out and logged in again. Whatever new processes are starting under those users are getting new FD limits. But for the daemon which is running under a headless user the changes are not getting reflected. what is the way by which the changes can be reflected for the daemon which is running under headless user ?

• Listing the routing table takes long time to complete

  - by Rafal Rawicki

  When I print routes defined on my computer using route, it takes about 5 to 20 seconds to complete. Why does it take so much time? With VPN enabled: $ time sudo route Kernel IP routing table (...) real 0m21.423s user 0m0.000s sys 0m0.012s With no VPN, this is about 5 seconds - still, computer can do a lot in this time. I've repeated my measurements few times, getting very similar results each try. My machine is Ubuntu with 3.0.0 kernel, but as far as I know, route on the other computers works the same way.

• HALEVT troubleshooting: VFAT usb storage device gets mounted with root:root user:group

  - by Nova deViator

  Hi, i'm banging my head for number of days around this problem. using Halevt for automounting, everything mostly works, but the only thing is that Halevt mounts external USB storage devices as root. So, as user i cannot write to files on them. Halevt gets run as halevt user on boot through /etc/init.d script. This is Ubuntu Lucid with Awesome WM. No GDM. Running halevt as user seem to not work (halevt runs but doesn't respond on Insert) I know HAL is deprecated and removed and i should probably write my own UDEV rules, but until then it seems there must a be simple hack that enables mounting VFAT/NTFS devices with specific uid/gid. this question/answer helps a lot, but not specifically to the above.

• HTG Explains: Which Linux File System Should You Choose?

  - by Justin Garrison

  File systems are one of the layers beneath your operating system that you don’t think about—unless you’re faced with the plethora of options in Linux. Here’s how to make an educated decision on which file system to use. The landscape of the Linux file system support is drastically different from Windows and OS X. In Windows and OS X you can find software that will add support for non-standard file systems, but both operating systems can only be installed on their native file system and third party support is added after the fact. Linux on the other hand has a vast array of supported file systems built into the kernel. But how are you supposed to know which file system to pick when installing? We will take a look at some of the most popular choices available and give you use cases to consider—the choice is ultimately up to you based on your needs.

• Is there any way to limit my Internet connection to a per program basis?

  - by Igoru

  My Linux connection is REALLY free. I live in Brazil, so where I live I can only have 1 Mbit/s. Yes I know it's sad, but it's not the point. Everytime I'm updating my Ubuntu 9.04 or downloading something, it does eat all my bandwidth. Like, while update-manager is downloading the packages, I can see by netspeed applet in my panel that the incoming traffic goes to 110 kB/s. And then, my Emesene suddenly goes disconnected, and I can't navigate. As you can imagine, I can't use my Internet connection again until the packages are all downloaded or I cancel the update in the middle. As I said, same thing happens when I'm dowloading something, but less intrusive and immediate. The question is: is there any way to limit that APT/downloads traffic to some way I can still use my other Internet services, or to reserve some bandwidth for common navigation tasks (like we have on Windows, but I forgot this thing's name, it's like "something packages".

• What has Ubuntu contributed to the Linux Kernel?

  - by Luis Alvarado

  This question is similar to this one: What unique enhancements and features has Ubuntu brought to the Linux Community but in this case it is directed towards what has Ubuntu contributed to the official Linux Kernel. For example, many times I hear about Intel contributing to patches for the Linux Kernel like the RC6 latest patches and any other related to the recent Sandy/Ivy Bridges. In another group, Android did an upstream patch and a lot of ARM patches have also come to the Linux Kernel. I have seeing only a small percent of companies and groups that have contributed to the Linux Kernel (http://kernel.org) but I want to know, since the beginning of Ubuntu till now, what has Ubuntu contributed to the Linux Kernel in regards to any aspect of the kernel. For Kernel information I typically go to http://kernelnewbies.org and http://kernel.org

• Best LXDE based distro/distro that supports LXDE?

  - by Misha Koshelev

  Lubuntu is nice - but it seems the LXDE version is not as up to date as Fedora LXDE Spin or even Debian squeeze with LXDE installed... I do like Chromium on Lubuntu though... its faster and a nice touch. So, any good recommendations? I am fairly used to Ubuntu and the dpkg/apt commands, but am willing to learn. I am looking for a lightweight 64-bit distribution for my main laptop (it is by no means "old" or "low spec" but I like that Lubuntu starts up in like 2 secs). Anyway as you can see I have a strong Lubuntu bias, but there are issues like: LXDE version seems not to be recent (esp in 10.04 version which seems to work more stably for me - with Nvidia drivers etc) 64 bit install is currently a pain - requires first install of minimal CD or alternate CD both of which required wired Ethernet, then install of lubuntu from PPA. Native 64-bit support would be nice. Linux Mint LXDE, for example, is also only 32-bit. Thank you so much
