  • Linux Mint something wrong with my .bashrc

    - by user2309862
    The path of my .basrc file is /home/vamsi/.bashrc It is weird that my file has nothing but the path I set. I think I am using a file at the wrong location or that I have lost my .bashrc file as none of the environment variables set here seem to work. #ANDROID_DEV ANDROID_HOME=/opt/android-sdk-linux export ANDROID_HOME PATH= $PATH:$ANDROID_SDK_HOME/tools export PATH PATH=$PATH:$ANDROID_HOME/platform-tools export PATH PATH=$PATH:$ANDROID_HOME/build-tools export PATH #MAVEN-PATH M2_HOME=/opt/apache-maven-3.1.0 export M2_HOME M2=$PATH:$M2_HOME/bin export M2 I was prompted to install maven2 in order to use mvn, but the android command cannot be found. Could you please help me find a solution to this issue. EDIT: Meanwhile,I tried this: export PATH=${PATH}:/opt/android-sdk-linux/platform-tools export PATH=${PATH}:/opt/android-sdk-linux/tools Now,the output of $PATH echoes: bash: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/android-sdk-linux/platform-tools:/opt/android-sdk-linux/build-tools: No such file or directory

  • Arch Linux Terminal (via ssh) + Dropbox but sync only 1 single selected folder

    - by Norfeldt
    Sorry for the weird title... I'm (still) quite new to linux and are doing shh commands to an Arch Linux device that has not screen output options. So everything has to be done in the terminal (not my super element). I use the linux device to play around with python (which is quite fun). Now I would like sync my script folder with dropbox. Since I don't have enought space to sync all my dropbox files to the device, I would like to know how I can set it up in a way that it only syncs with the folder I choose. At the time being I have not installed dropbox because I'm afraid that it will immediately begin to sync all my dropbox folders onto my linux device. BONUS INFO: I already have created a folder in my dropbox that I that contains some py scripts I would like to have synced with my linux device.

  • Multiple Internet connections, multiple networks and split access in Linux

    - by Swapneel Patnekar
    I am having trouble setting up multiple internet connections for split access in Linux. We have 3 internet connections from 3 different ISP's. We want to configure our Linux gateway machine such that our three internal networks 10.2.1.0/24, 192.168.20.0/24 & 192.168.2.0/24 use ISP1, ISP2 and ISP3 respectively in a split access manner. Outlined below is the layout/settings, Interfaces of the Linux Gateway connected to Routers: eth0: 10.1.1.2<---------->10.1.1.1(Internal Interface of ADSL Router)[ISP1] eth1: 192.168.15.2<------>192.168.15.1(Internal Interface of 3G Router)[ISP2] eth3: 192.168.1.2<------->192.168.1.1(Internal Interface of ADSL Router)[ISP3] Kindly note that none of the interfaces in the Linux gateway has a public static IP address. Routers of ISP1 and ISP2 get assigned a dynamic public IP address when connected to the Internet, router of ISP3 has been assigned a public static IP address. Interface of Linux gateway connected to a switch, eth4: 10.2.1.1(LAN Interface for ISP1) eth4:0 192.168.20.1(LAN interface for ISP2) eth4:1 192.168.2.1(LAN Interface for ISP3) eth4:0 & eth4:1 are virtual interfaces with eth4 being the interface connected physically. Based on http://linux-ip.net/html/adv-multi-internet.html I've set the following routes, ip route flush table 4 ip route show table main | grep -Ev ^default | while read ROUTE ; do ip route add table 4 $ROUTE done ip route add table 4 default via 192.168.15.1 ip rule add fwmark 4 table 4 ip route flush cache Additionally, using the following iptables rules to mark & route packets as per the guide mentioned above : http://pastebin.com/KzWHFGJA At this point, computers from 192.168.2.0/24 network are successfully able to reach the Internet through ISP3. 192.168.20.0/24 and 10.2.1.0/24 are unable to access the Internet through ISP1 and ISP2 respectively. Any inputs will be much appreciated !

  • Prevent auto mounting Android sdcard under Linux Mint

    - by BullShark
    I recently obtained an older Android phone, so that I could test Android Apps on it. I've needed it because I have a Nexus 7 but not older Android versions, hardware, etc. to test on. I'm having a problem with it under Linux Mint with Cinnamon. When I plug the phone in, or remove and plug the sdcard from the phone back to it while the phone is plugged in, Linux automatically mounts the sdcard. This is a problem because once it is mounted under Linux, it dismounts from the phone running Android 2.3.5, and I can no longer test Android Apps I write that require the sdcard to be present, writable. I went to Menu System Tools System Settings System Details Removable Media, and it brings up this window. I have changed the settings to always "Ask what to do" on "Select how media should be handled". However, the sdcard still gets mounted and then I am asked how I want to open these files (media players, photo importers, file browser, etc.). If I click the checkbox for "Never prompt or start programs on media insertion", then the sdcard is mounted, and I am not asked how to open these files. Eject is just a noob word for Ubuntu users that means umount (unmount) like "Adminstrator" is another ubuntu noob word for the root user. And if I unmount the sdcard, the phone doesn't recognize it again until I take the sdcard out and plug it back in. The phone sees it for a brief moment until Linux Mint takes it over. There are 2 possible solutions and maybe more: 1) Prevent Linux from automounting sdcards some how 2) Tell Android not to allow the computer it is plugged into to take over the sdcard, HOW? Edit: I found out how to prevent the sdcard from being automatically mounted: Now it gets recognized by Linux: bullshark@beastlinux ~ $ dmesg | tail -n 25 [597212.218323] sd 21:0:0:0: [sde] Attached SCSI removable disk [597212.218639] sr 21:0:0:1: Attached scsi CD-ROM sr2 [597212.218910] sr 21:0:0:1: Attached scsi generic sg7 type 5 [597217.139373] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597217.140726] sd 21:0:0:0: [sde] No Caching mode page present [597217.140735] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.143595] sd 21:0:0:0: [sde] No Caching mode page present [597217.143602] sd 21:0:0:0: [sde] Assuming drive cache: write through [597217.152240] sde: sde1 [597389.751008] 4:2:1: cannot get freq at ep 0x84 [597390.238742] 4:2:1: cannot get freq at ep 0x84 [597624.903132] sde: detected capacity change from 1977614336 to 0 [597637.677763] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597637.679616] sd 21:0:0:0: [sde] No Caching mode page present [597637.679626] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.682508] sd 21:0:0:0: [sde] No Caching mode page present [597637.682515] sd 21:0:0:0: [sde] Assuming drive cache: write through [597637.692758] sde: sde1 [597661.857979] sde: detected capacity change from 1977614336 to 0 [597688.775455] sd 21:0:0:0: [sde] 3862528 512-byte logical blocks: (1.97 GB/1.84 GiB) [597688.776814] sd 21:0:0:0: [sde] No Caching mode page present [597688.776823] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.780055] sd 21:0:0:0: [sde] No Caching mode page present [597688.780062] sd 21:0:0:0: [sde] Assuming drive cache: write through [597688.788639] sde: sde1 bullshark@beastlinux ~ $ However, the phone still unmounts the sdcard upon being detected by Linux.

  • nice linux distro for vxl itona

    - by akiva_eshbal
    I'm trying to have some productivity with my VXL ITONA thin client. it is very minimalistic: 128 MB disk, 64 MB ram, with an Ezra via processor. out of the box it comes with GIO linux, I could run from a USB key puppy linux and damnsmalllinux (but I couldn't make them installed on the SSD drive). more customizable distros like arch-linux and slax fail to load due to kernel failure caused by lack of cmov instruction in the VIA processor. I really like to make it usable, can you please recommend me a nice distro? I'm afraid the Gentoo solution is too scary for me right now (compiling a linux kernel over a a thin client is too much) thanks!

  • Linux Distro for Beginners

    - by XLR3204S
    Well... I know that's the question arising all over the Internet, but I couldn't find an answer to suit me after googling for quite some time. I'd like to get a Linux distribution, and start learning using the CLI. I'm looking for a distribution already having GNOME installed, as I'll be using Linux-Command.org as my learning resource, and I'm not very familiar with CLI-based web browsers. I'd mainly like to get to know my way around a UNIX-based system, and then I think I'd like to pick up a CLI-only distribution, and start doing more complex stuff. I've tried Ubuntu, Fedora Core, OpenSolaris and FreeBSD (the last two aren't linux distros, I know). Ubuntu and FC are fine, they do come with Firefox, but I'm not really sure they're meant for learning purposes. OpenSolaris was OK as well, but I haven't got to play with it enough. FreeBSD 7.2 did not want to install itself on my 13" MacBook Pro, it generated a kernel panic everytime while copying the files to the disk. So to sum this up, I'm trying to learn Linux, and I'm willing to invest time into this (that is, not giving up when the first problems arise). I also have intermediate knowledge of C++, if it helps, and I'm also using the CLI-vim to write small C++ CLI-based programs, so text editing should be any problem. And... speaking of Macs, how am I going to be limited if I try to learn how to use UNIX-based systems using the OS X Terminal? It uses bash 3.2, isn't this the same shell as the one found on most of the Linux machines? How does the fact that OS X is based on FreeBSD 4.4, if I'm not mistaking, affect this? Thanks in advance, and hopefully, I'll have a starting point ASAP.

  • Best Linux distro for load-balancers?

    - by Vimvq1987
    I wanted to try HAProxy/Linux Virtual Server like front-end load-balancers, but as far I know, they're Linux-based software. I don't have any experiences with Linux yet. so there're quite many questions to ask: What is the best Linux distro(s) for load-balancing? I plan to use VirtualPC to run some virtual machines. How much RAM is the best for each machine run that distro? I want to simulate a load-balancer with can handle about 100 hits/second, is it possible? Thank you very much!

  • How does the linux kernel manage less than 1GB physical memory ?

    - by TheLoneJoker
    I'm learning the linux kernel internals and while reading "Understanding Linux Kernel", quite a few memory related questions struck me. One of them is, how the Linux kernel handles the memory mapping if the physical memory of say only 512 MB is installed on my system. As I read, kernel maps 0(or 16) MB-896MB physical RAM into 0xC0000000 linear address and can directly address it. So, in the above described case where I only have 512 MB: How can the kernel map 896 MB from only 512 MB ? What about user mode processes in this situation? Where are user mode processes in phys RAM? Every article explains only the situation, when you've installed 4 GB of memory and the kernel maps the 1 GB into kernel space and user processes uses the remaining amount of RAM. I would appreciate any help in improving my understanding. Thanks..!

  • Files are piling up in /usr/src/. How can I stop this?

    - by Bogdanovist
    I have been having many serious system issues over the past few weeks and have been scratching my head as to why. I've now worked out that this problem is having no inodes left on the root partition $ df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda6 732960 724565 8395 99% / udev 125179 518 124661 1% /dev tmpfs 127001 464 126537 1% /run none 127001 4 126997 1% /run/lock none 127001 8 126993 1% /run/shm /dev/sda7 5234688 144639 5090049 3% /home What is the cause?

  • Obtaining Embedded Linux Experience

    - by Thomas Matthews
    As an embedded firmware developer, I have used operating systems such as WinCE, Nucleus, ThreadX, VRTX and some background loops. There are more opportunities for me if I had Linux OS experience, or perhaps some certification. In my research, the only way to get Linux experience is to have your company move to a Linux OS. All the recruiters and HR folks won't let you in the door unless you have Linux experience. I haven't found any Universities that teach Linux. Recruiters and HR want some tangible proof (starting up your own Ubuntu box or playing with it doesn't count). So, how does one get into the area of Embedded Linux without Linux experience (I have Unix and Cygwin experience, but not Linux)?

  • Moving from windows to linux

    - by rincewind
    I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

  • Recovering from apt-get upgrade gone wrong due to a full disk

    - by Peter
    I was performing an apt-get upgrade on an Ubuntu 12.04.5 LTS box that hadn't been updated in a little while and the upgrade failed due to 'No space left on device'. After a little while I worked out space meant inodes and I have freed some up but unfortunately things have been left something askew. I have tried manually installing the old versions of packages mentioned using dpkg -i but that doesn't help. I have tried apt-get upgrade and apt-get -f install to no avail. Results are below.

  • Little girl friendly versions of Linux (or themes for Linux)

    I'm going to install Linux on a PC for a daughter (age 7) of a friend of mine. I recently came across Hannah Montana Linux. The parents don't want a commercially branded thing going on, so no Hannah Montana. But I was wondering if there were other linux distros - or desktop themes - that would be cool for a 7 year old girl. All suggestions welcome.

  • Linux Newbie: SSH or VNC for linux admin tasks

    - by Dirk
    Longtime Windows user, looking to get my feet wet with Linux. Since Windows makes comparatively little use of the command line, I'm naturally more comfortable with GUI tools for remote server administration tasks. However, before i rush out and install a VNC server on my Linux box, I want to get a sense of how many of Linux's various packages actually offer GUI front end. If not many, then it's probably not worth the effort.

  • Best Linux dist for .NET developer looking to learn Groovy (and never used Linux)

    - by blade7
    Hi, I am planning to learn Groovy, but I want to do so on a Linux OS (because such an open minded approach will teach me more about IT and I have Windows Server VMs). Anyway, which Linux distro is the easiest to use and requires the least amount of knowledge on commands etc? As I am new to Linux, I want a dist. which doesn't require command-level knowledge (I am not at this level with Linux but I am with Windows Server). Which dist would be most suitable for me and has development utilities built in? Thanks

  • Easiest linux distro creation

    - by QAH
    Hello everyone! I have been trying to create my own customized distro of linux (preferably some kind of Debian system like Debian, Ubuntu, Knoppix, etc). I want to make it specifically for playing games. This is just a pet project for me and while I know linux pretty well (bash, gcc, g++, gdb, etc), I'm not that great with knowing the kernel. So that puts making my own distro from scratch out of the question. I went on to trying to create remasters of Knoppix and it worked for me but it was a very long process since knoppix is meant to be a live CD and I was running it in VirtualBox. So what is the easiest and fastest method of making your own distro? Also, can I install ubuntu or some kind of linux to a computer make changes to it, and then make a distro off of that installation? Please help me with this, Thanks

  • Linux memory fragmentation

    - by Raghu
    Hi all, Is there a way to detect memory fragmentation on linux ? This is because on some long running servers I have noticed performance degradation and only after I restart process I see better performance. I noticed it more when using linux huge page support -- are huge pages in linux more prone to fragmentation ? I have looked at /proc/buddyinfo in particular. I want to know whether there are any better ways(not just CLI commands per se, any program or theoretical background would do) to look at it.

  • mini linux to use dd and access HD and/or USB

    - by acidzombie24
    I was thinking about something. I want to install a 7gb partition and store 2 compress disk image and install linux to it. I want it to be light. What i would like to do is hide the grub loader (or anything) and if i want to reformat my PC press a certain key on startup. Which will then load the linux OS and then i can use dd to restore the partition i want I plan to use windows XP and windows 7 as my main OS and virtualize anything else i need (vista, dummy XP for testing, multiple linux distos, etc). Bonus points if you can tell me how to hide the partition in windows so XP and 7 cant touch it

  • __modver_version_show undefined error when building linux kernel 3.0.4 version

    - by Jie Liu
    I tried to build the linux kernel 3.0.4 on ubuntu 11.10 in virtualbox. Here are my steps: Download the source code tar xjvf linux-source-3.0.0.tar.bz2 cd linux-source-3.0.0 make menuconfig, changed nothing but used the default config and save to .config make Actually I think it should be 3.0.4 because from the Makefile I could see VERSION = 3 PATCHLEVEL = 0 SUBLEVEL = 4 EXTRAVERSION = Then at stage 2 which is to make modules, an error happened: ERROR: "__modver_version_show" [drivers/staging/rts5139/rts5139.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 Perhaps because 3.0.4 is a new release so that I can not find any same problem asked nor any solution to it.

  • how to save installs on linux usb

    - by user2508947
    I'm a new person at Linux and am running Linux mint 15 cinnamon from an 8GB sandisk pendrive. I cannot dualboot it with windows until my friend (who is a genius at computers) backs up my windows (apparently). The thing is, I cannot save what I have done on it. for example, if I install drpython on my Linux and switch off my laptop, the next time I switch it on, it's all gone. can anyone tell me how I can save what I have done? Thanks in advance.

  • Linux and ClickPads

    - by John
    I just got my Arch / Windows 7 dual-boot setup running... except for one thing. I have an HP dv6-3127dx laptop, which is an issue when it comes to Linux because it does not have a traditional touchpad, but a "ClickPad." This means where the left and right buttons exist, it is also sensitive to moving the pointer. The issue comes in when I try to steady the mouse with one finger, while clicking the left click with another, because the mouse freaks out. It's also an issue because it's not recognizing the right click whatsoever. I am currently using the default Synaptics drivers downloaded from pacman on Arch Linux, running Linux v2.6.36. EDIT: The question of course is, how can I fix this?

  • What is the sequence followed by the Linux kernel to configure a device?

    - by Jaime Soriano
    As I understood after reading the chapter related to The Linux Device Model in the Linux Device Drivers 3rd Edition, when a new device is configured, the kernel follows more or less this sequence: The Device is registered in the driver core (device_register(), what includes device initialization) A kobject is registered in the device model It provokes a hotplug event Bus and drivers are checked to see which one matches with the device Probe Device is binded to the driver My main doubt is, in step 1, when is device_register() called and what info should be yet in the device struct? Is it called by the bus to which the device is connected? Any example in the code? Have I misunderstood something? :)
