• Is there a way to show icons on a git repo folder like tortoiseGit?

  - by shengy

  Is there a way which could let me know all the file status by just looking at the folder view, like what TortoiseHg, TortoiseSVN, TortoiseGit did on windows? Now my git repo folder looks the same as other folders. If I want to view file status I have to type git status in the command line. I want some icons which could inform me the file/folder status at my first glance on the folder view. I'm using Ubuntu 12.04 EDIT I googled it, and what I'm asking for is called the overlay icon.

• How do I access an external drive mounted on a machine on my own network?

  - by avilella

  I've got one desktop computer Ubuntu 11.04 with an external USB drive mounted on it on the home WRT54L Linux network (192.168.0.2), and when I arrive at home with my laptop, I want to be able to mount the external USB drive from my Ubuntu 11.04 laptop (192.168.0.3) to the desktop, without having to unplug it from the desktop, that is accessing it. Is it possible to send a remote mount command to the desktop usb drive from my laptop? Ideally something that creates a local mountpoint I can just call locally from the programs installed in my laptop, like: username@laptop ~ ./myprograminlaptop /my/file/which/is/actually/on/the/desktop/file.txt

• Issue in upgrading Zenity

  - by user109187

  I am currently using Ubuntu 12.04 I am attempting to install steam using the post in omgubuntu. However, I am running into problems when the command sudo dpkg -i steam.deb && sudo apt-get install -f. I get the message that the version of Zenity is too low. The minimum required version is 3.4.0-0ubuntu4 while I currently have 3.4.0-0ubuntu2 I tried sudo apt-get install zenity but it does not update it and gives the following message: zenity is already the newest version. I also tried installing via the ubuntuupdates website for the latest version of Zenity, but it still does not work.Ubuntu Software Centre indicates that it is already installed and provides no option to update. :( Any idea how to update Zenity in my system?

• Bind9 not doing anything with forwarded query responses?

  - by Rykaro

  I have a Bind DNS server that is the local production DNS server and a Windows 2008 R2 domain controller which provides DNS for a lab environment with the domain xyz.lab. I've configured the Bind DNS to forward DNS requests for the domain xyz.lab to the Windows DNS server with this config: zone "xyz.lab" { type forward; forward only; forwarders { x.x.x.x; }; }; zone "x.x.x.in-addr.arpa" { type forward; forward only; forwarders { x.x.x.x; }; }; And Bind options are (the all_internal acl includes the subnets of both the production and lab networks as well as the loopback of the bind server): allow-query { all_internal; }; allow-recursion { all_internal; }; allow-transfer { none; }; notify no; minimal-responses yes; version "unknown"; Unfortunately, when I do an nslookup or dig on the bind server for a host on the lab domain, the request times out. The logs on the Windows 2008 DNS server show it receiving the query and responding to it and a network packet trace shows the query responses arriving at the Bind DNS server. The servers reside on the same switch with a router providing connectivity between the layer 3 subnets (production and lab are on different subnets) and there is a round trip time of between 3ms and 5ms on pings between the two servers, so I don't think there is an issue with latency causing a timeout of the query. In summary a query-response arrives back at the Bind server and the nslookup/dig times-out. Why does the Bind DNS not seem to be doing anything with the query responses when it receives them?

• What Design Pattern is separating transform converters

  - by RevMoon

  For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

• Writing files to an Airport Extreme using afp

  - by Bill Oldroyd

  Using Nautilus I can connect from Ubuntu 12.04 (64-bit) to my Apple Airport Extreme using user & password without a problem. I can read, browse folders and delete files. However I cannot write files, the file is created, but the contents of the file are not transferred. The transfer fails with the error message "kFPMiscErr" which I think means that "authentication has already been established" ?. I have tried the command line tools for access using AFP but these do not work either. Is there a solution to this problem ?

• How to connect to other Ubuntu machine as X Server?

  - by Tibo

  When I want to work on my local Linux machines from windows, I use Putty+Xming and I set the Xming port in Putty connection settings. This way I have a terminal on the machine and if, for example, I run the command 'firefox' a firefox window is opened in Windows (while it is really running on the Linux machine). I want to do the same thing from other Linux machine (they are both Ubuntu machine) connect by SSH and become this connection X Server so any graphic component will be opened on local machine. How can I do that?

• How to run CLI commands from the launcher?

  - by user50849

  I press ALT+F2 key on my keyboard, and get the launcher HUD up. From there I enter a command as I would in a shell, specifically vlc ~/Music/* -Z. If done from a shell, vlc starts and begins to play music. However, when done from the launcher, VLC replies: File reading failed: VLC could not open the file "/home/[username]/Music/*". (No such file or directory) user Your input can't be opened: VLC is unable to open the MRL 'file:///home/[username]/Music/%2A'. Check the log for details. I can't quite figure out what the difference is.

• How to install libdvdcss?

  - by skwd

  I'm relatively new to Ubuntu and I'm trying to figure out how to play DVDs. I've read through a lot of forums, and got to the one asking how to read encrypted DVDs. I was able to do the first step and installed libdvdread4, but when I got to the second step of installing libdvdcss, I got what amounted to error messages. This is the command I ran: sudo /usr/share/doc/libdvdread4/install-css.sh Is there something important that I should know? As in, probably something basic that I don't know because I'm new...?

• What should be the correct ownership of /tmp /var /usr and subdirectories?

  - by sbergeron

  For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.

• alx driver not working properly

  - by user292768

  My alx driver seems to be working fine for everything except apt-get. I can navigate to web pages, the ping command works just fine, but whenever I try to do apt-get update or apt-get install it hangs on trying to connect to whatever archive it's trying to pull info from. There's no error message, nothing to imply that it can't connect, it just hangs there and does nothing at all. I've tried re installing alx, upgrading/downgrading my linux kernel, downloading source and building alx from scratch, etc etc but nothing works. Does anybody else have this problem/know how to fix it?

• Upgrade from 13.04 to 13.10 fails early on

  - by Bob Lewis

  I am attempting to upgrade from 13.04 to 13.10. Right after the early on message Downloading file 1 of 2 and then it goes on to 2 of 2 the upgrade process dies. A reboot and attempt again fails at the same point. This is a 64 bit system with an SSD for the boot drive. If memory serves me when attempting to do same from the command line I saw some dbus error which may or may not be related. Any help much appreciated. Obviously I could attempt a fresh install which would likely succeed.

• /build folder used by PEAR

  - by Paul

  I've just noticed a root directory (/build) which I can't seem to find any information for. It looks like it's some sort of staging ground for PEAR (PHP). There are only two folders of different php versions in it, and each of those has a few PEAR tar files I've installed (via the PEAR command line). I'm really only asking this question because I find is strange PEAR (and only PEAR) would create its own root directory to store files. Is this normal? Does Ubuntu provide a /build directory for applications to use?

• Linux can dual display but windows can't?

  - by Mr_CryptoPrime

  I have two monitors, one that is hdmi-to-dvi and the other vga-to-dvi. I have an AMD HD Radeon 6900 series graphics card installed. I got Ubuntu to display dual monitors, but then I restarted for an update and then Ubuntu wouldn't even boot in recovery mode, it just kept cycling forever...displaying something about "timeout: killing [filepath] [hexadecimal]. So I tried booting into windows (7-professional) and it crashed and displayed this after rebooting: IRQL_NOT_LESS_OR_EQUAL, PAGE_FAULT-IN-NONPAGED-AREA. I went into Bios and reverted to the system defaults and ran system restore and it booted ok, but the dvi-to-dvi monitor would not display. I made sure my drivers were updated and catalyst was updated. Also through research discovered only one is for vga and the other is digital only, so I put the vga-to-dvi in the vga slot and so on. Neither windows or catalyst will detect the dvi-to-dvi montior. Any suggestions? Thanks. EDIT: Found out that booting into Ubuntu with only one monitor (using either monitor with either cable) worked perfectly fine. I could then add another monitor and it displays ok. However, it will, out of the blue, suddenly distort the display. At first I thought the computer crashed, but it is something with the video output from the GPU to the monitor because I pushed the power button and it would refresh every 5secs or so and I could see the "Ubuntu will power down in X seconds", even though it was horribly distorted. Any ideas what's causing this?

• Ubuntu 12.04 Server monitor goes into sleep mode (no display) after fresh install

  - by xamox

  For some reason I can boot and either use Ubuntu 12.04 server edition, or desktop version. I can live boot the disk, I can go through the installer, or even use the ubuntu alternate installer. But for some reason after the install completes and I reboot the monitor seems to go back into sleep mode and then never loads the command prompt. This is on an industrial adlink MXE-1300 PC. I've installed ubuntu server fine on other models of adlink machines but this one doesn't want to seem to play nice. To me it seems like if it was a video card issue than I could never even load the installer or run ubuntu in live mode. Any thoughts or troubleshooting tips would be greatly appreciated.

• In-memory DB to perform intersects on set slices

  - by IanC

  I have a specific programming need where I need to efficiently store large sorted sets in memory, query them for ranges, and intersect them against other sets that are also queried for ranged. I am looking at Redis, but I can't see a range slice command. MongoDB can only use 1 index, so it has to perform row-level scans, whereas I wish to process using columns that are intersected. I'm also looking at Counchbase, but can't easily determine from the documentation if it is suited to this. I know it uses Memcached, which is AFAIK not suited to this usage. Could anyone share potential solutions for this specific problem? EDIT For example, I need to perform the following: Get the IDs of all cars where the price is between 2000 and 3000, and intersect that will all cars where the engine capacity is between 3000 and 4000.

• error when installing rmagic gem on Ubuntu 12.04 for Ruby on Rails

  - by PeaceDefender

  0 down vote favorite I am trying to get my Ruby on Rails application working and installing RMagic gem. But I get an error that says "Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries." Altough I have ImageMagick installed with its dependences. Terminal log : http://pastebin.com/vcgkbwZR I even tried to installed RMagic from Synaptic, but I get the same error when I run "bundle" command. Through my search, some people had problem with lib dependencies, but I believed I have them all installed. Another solution I found is this ( error installing RMagick from gem ) a little bit old and not sure if it is going to work for 12.04. BUT, I don't know where those configurations should go.

• What to do about this gnome-keyring message?

  - by arroy_0209

  I upgraded from ubuntu 10.04 to 12.04 and installed lxde. Since then whenever I try to print some file (or use command lpstat), I get this message on the terminal: "WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-SZ59jJ/pkcs11: No such file or directory". This is beyond my knowledge and from search I only realize that this mey be related to security (as learned from gnome-keyring on wikipedia). I have no idea what to about this warning. Can anybody please suggest? Evidently as stated, I am not using gnome desktop, I choose lxde session at the time of logging in.

• How do I fix the audio on my laptop. model Fujitsu B6220

The sound card show up under lspci as: "00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)" What would be the command to reinstall the audio subsystem?

  Hi, This is my first post on serverFault and my first entry in to web server configuration. The hardware and software. CPU: GenuineIntel, Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz OS: Linux 2.6.18-128.el5 Memory: 2Gb Background. I am running a small database (MySQL), around 1000 records with each record containing 44 fields. At the start of each day “00:01” the tables are cleared and populated with fresh data. The are 10 remote PCs all running Winodws XP and Firefox internet browser. All remote PC’s are connected to the internet using a min 4Gb broadband connection. Each remote PC runs a URL which displays a dynamic page of data which is refreshed every 20 seconds. This is a continual process 24 hours a day. I problem I am having is on odd occasions throughout the day the PC browser error with “Server taking too long to respond error”. What I am trying to find our is if I have the correct setting in the httpd.conf file on the server. Any help or advice anyone can provide would be very helpful.

• How do you assign commands to keys to in Terminal?

  - by NES

  Is there a solution to assign special key combinations to words in terminal use. For example the less command is very usefull and i use i a lot to pipe the output of another process through it. The idea would be to set up special key combinations that are only active in terminal use assigned to write different commands? So pressing CTRL + l in terminal window could write | less or CTRL + G could stand for | grep Note: i just mean adding the letters to commandline not execute the finally. A similar way what's tabcompletion but more specific.
