• Ad-hoc network(hot spot created) not detected by android phone

  - by Nirmik

  I created a hot spot via network wireless use as hotspot. Other laptops successfully detected the hot-spot,could connect and use it without any problem. But no android phone could detect it.! I tried with many android phones but none could.(I found out that even an ad-hoc created in windows is not detected by any phone) So is there anything wrong i am doing(rather i am not doing anything actually other than clicking on the "use as hotspt" button..but still..)? or is that the network cannot be shared with phones? and if not,how can i share it with phones?

• Boot Ubuntu on smartphone SD card?

  - by berad

  Now here's what I want: Ubuntu on the SD card that lives in my phone. I like using Ubuntu portably and my phone as a flash drive, but I haven't been able to make these work together yet. I've tried booting off my Huawei U8800 (Android 2.2) and Nokia E66 with a micro-SD card (with 11.10, boots OK in a card-reader) on an eeepc 901 without luck. The Huawei doesn't show up in the BIOS boot menu. BIOS sees the Nokia but halts at "Boot error". I guess this is related to the phone's flash drive emulation and how it handles bootsectors, but I don't know enough about how that works to go any further. Has anyone succeeded in this?

• Accessing network shares through ASP.Net

  - by jkrebsbach

  In my impersonation enabled web site I needed to access files on a network share.  Running locally, everything worked fine. After deploying out to the dev server and hitting the web site from my PC, things fell apart. With impersonation enabled, we can access files on the server itself, but a network share is another story.  Accessing a share on another server, we encounter the infamous "double hop" situation, were the credentials have already been digested on the web server and are not available for the file server. We need to either expose the shared files to the identity IIS is running under, or create a new impersonation context.

• ipheth notification at login prompt

  - by spudwaffle

  On my command line only Ubuntu machine, the login prompt occasionally shows a warning: Ubuntu 12.04 LTS myserver tty1 myserver login: [833747.589882] ipheth: ipheth_rcvbulk_callback: urb status: -71 Nothing is obviously wrong with the system, and I can enter my username and password without issue. What does this message mean and should I be worried about it? Edit: I've found plugging in and then removing my iPhone from the computer causes this message. I'm still looking for what it means.

• Ubuntu 12.04 - no wireless network recognized

  - by Itai

  I just installed Ubntu 12.04 along with WIN7 on the same laptop - Dell Vostro-3560. Now, on Win7 i can access to different wi-fi networks. However, when i am logging onto the Ubuntu section (after re-starting my laptop) - an error message appears: "Disconnected - you are now offline". When i take a look at my network menu (in the upper bar on the screen), i see that no network is found (and i have a few of them in the area...). I tried to look around but really could not find a concrete practical solution to this specific problem, would appreciate any solution from anyone out there that had this problem and solved it. Thanks... Itai

• Asus 1001P freezes after chaging network settings

  - by auntiquarian

  I'm running Ubuntu 11.04 on a Asus PC 1001P in a dual boot environment with XP. All has been running fine for several weeks, but: I've just changed ISP (from Tiscali to BT), and had already sorted out connection, registration, etc. on a Dell laptop. On the Asus I went into Ubuntu to alter the wireless network details (i.e. selected the new network, and entered the password). Ubuntu immediately started running slowly, and after rebooting it now freezes when it gets to the Ubuntu logo and gets no further. Please help, lovely Ubuntu experts.

• Creating an install drive - can not open output file autorun.inf

  - by user226881

  I am trying to make an install/boot drive for a computer that has no operating system and no optical drive. I used the ISO from Ubuntu.com and the burner from pendrivelinux.com. When the program starts writing to the flash drive, there is an error displayed that says : "0 can not open output file E:\autorun.inf" But continues to write data. After it has finished, I remove the drive and insert to the other computer and turn it on, but it never finds a drive to boot from. What is causing this problem and how can I fix it ?

• How to create a bootable system with a squashfs root

  - by cldfzn

  My goal is to be able to take a customized root file system loaded with the software I want. So far I've created a squashed filesystem using debootstrap and chroot to install the software I want on the system. The problem I am now running in to.. whenever I boot in to the system, my user accounts that were set up in the chroot do not work. First boot everything works out, second boot I can't log in. That is baffling to me. Any one know a reason or a place to start looking? Update To get a working system with a squashfs filesystem: sudo apt-get install live-boot live-boot-initramfs-tools extlinux sudo update-initramfs -u Create a squashfs file from a bootstrapped or running ubuntu filesystem with whatever packages you want available. https://help.ubuntu.com/community/LiveCDCustomizationFromScratch provides good instructions for creating a debootstrapped system to build on. Format the target drive with ext2/3/4 and enable the bootable flag. Create the folder layout on the target drive and install extlinux: mkdir -p ${TARGET}/boot/extlinux ${TARGET}/live extlinux -i ${TARGET}/boot/extlinux dd if=/usr/lib/syslinux/mbr.bin of=/dev/sdX #X is the drive letter cp /boot/vmlinuz-$(uname -r) ${TARGET}/boot/vmlinuz cp /boot/initrd.img-$(uname -r) ${TARGET}/boot/initrd cp filesystem.squashfs ${TARGET}/live Create ${TARGET}/boot/extlinux/extlinux.conf with the following contents: DEFAULT Live LABEL Live KERNEL /boot/vmlinuz APPEND initrd=/boot/initrd boot=live toram=filesystem.squashfs TIMEOUT 10 PROMPT 0 Now you should be able to boot from the target drive in to your squashed system.

• How can I format my active hard drive to NTFS?

  - by Ghost

  Believe it or not, I'm not too happy with Ubuntu. Well, let me rephrase that. I like it, but the only thing I don't like about it is that it's too much of a hassle to get a game to work. I'm trying to install Windows 7 with a 4GB flash drive, but my error that comes up is that my hard drive I'm trying to install on is in ext4. I need to format it to read NTFS. I can't seem to find any topics on how to format an active hard drive. I found a topic that explains how to move Ubuntu to a new drive, but it's a bit confusing to me. Please help! (Please don't disregard this topic just because I want to go back to windows)

• Ubuntu 12.10 Network Connection menu GUI doesnt work properly

  - by wax

  Many a times I have seen When I click on network connection(besides volume icon), I am unable to select any options. When I hover over VPN connections, the list shows nothing. I have added many VPNs. Network menu becomes non responsive to any clicks. This is annoying because I am not able to connect to any of the VPN connections. "Enable Wireless", "Edit Connections" or any other option doesnt work at all. Restarting ubuntu fixes this issue. But problem starts randomly again and restarting my laptop is the only way to fix it. Is this a known bug? Any ways to fix this prob?

• Remove "computer" and "network" categories from Nautilus sidebar (ubuntu 12.04 running Cinnamon 1.4)

  - by utnubu_user

  I am wondering if it is possibly to completely remove the "computer" and "network" categories from Nautilus sidebar. I would like to do this because the locations that fall under them cannot be edited and I don't use those. Instead, I prefer to specify my own locations which I can do through the Bookmarks. This is all fine, but the "computer" and "network" just sit there doing nothing (potentially distracting). It seems these categories are hardcoded in Nautilus 3.4.2? At least I can't find a way to remove them. Any suggestions are welcomed.

• Why can't I mount the Ubuntu 12.04 installer ISOs in Mac OS X?

  - by eric

  Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC. It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility. When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened. The reason given for the error is no mountable filesystem. However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD. What has changed in this release to cause this? Is there something wrong with the current ISOs? The OS X machine I am using is only two weeks old and is having no issues with any other ISO.

• Massive vehicular network simulator

  - by IvanK

  I am interested in making a vehicular network simulator (vehicular network as in vehicles can be equipped with radios and when they come in range they can talk with each other). I want to be able to scale to 1000s of nodes if not more. I am quite frankly torn on how to do, or even which language to use or whether I should instead be using some other piece of software/code. I know that this should depend on a lot of design decisions that I may have, but it would be great if somebody can point me towards the right direction. I was planning to use a multi-threaded architecture, but not sure whether it will add to the complication or make it easier. Also if I go for a multi-threaded architecutre, do you think that 'Go' language will be a good choice?

• Keyboard activation bug

  - by Skydreamer

  I'm using Ubuntu's last version and there's still a little problem on my installation (already on previous versions). When I start the computer and reach the login screen, I have to wait about a minute to be able to begin to use my keyboard. That's not a real problem but that's kind of annoying. I've tried some things such as a lsusb via ssh and it worked and activated the keyboard without waiting. So I've tried to put it in the crontab (with @reboot) but it doesn't really work. Has someone got an idea how to solve this bug ? Thank you in advance.

• Is there a way to sync my laptop's Ubuntu install with a jumpdrive Ubuntu install?

  - by trezy

  So I'm doing a fresh install of Ubuntu on my laptop right now. I also have a jumpdrive with Ubuntu installed on it with a persistent setup. What I would like is to be able to plug the jumpdrive into my laptop and have the installs sync certain data. I don't want docs and such to sync of course, but I would like some software to sync with installs and updates, mostly security and recovery stuff. Here's an example of what I would like to happen: I already have TestDisk installed on my jumpdrive but I haven't booted the drive in a while. I plug it in to my laptop where TestDisk has been updated and Wireshark has been installed. I would like the jumpdrive to check to see what has changed on the laptop install (in this case TestDisk has updated and Wireshark has been installed) and make those changes to the jumpdrive. Is there any kind of software to do that?

• Cannot find other computers on the network

  - by RDNY

  I have several issues trying to connect to my network. This is not the problem connecting to the Internet through the same router. All my computers are running Windows 7, Vista and XP Pro. I can't see them and they can't see me either. I've already install Ubuntu Studio 11.10 three times and still not showing the network icon at all. I'm new to UBUNTU and LINUX in general. I can't find my group name either.

• Ubuntu not saving files and settings when running from flash drive

  - by user81217

  How can I make Ubuntu run completely off of a flash drive? I have downloaded Ubuntu onto a 4gb flash drive but no changes I make are saved between sessions. I want to be able to run and save everything I do to the flash drive. I don't want it interfering with my hard drive at all. I just want to be able to plug my flash drive in the computer boot Ubuntu, and for it to save my changes. E.g. When I install Google Chrome, when I reboot it isn't there.

• Truecrypt rescue usb

  - by geekbutitsokk

  i have found tutorials on their official forum and on the internet about how to make a truecrypt rescue bootable usb stick. I'm guessing anyone who can answer will know what that is already, but it is basically just a way to boot into the system using a usb stick instead of a DVD. But the only problem is all of these tutorials involve using Grub4Dos, and i cannot run Grub4Dos on 64 bit windows 7. Is there any other alternative method? Thanks!

• Wifi network stopped being visible (and usable) (Linksys wag320n)

  - by s427

  Basically, my wifi network simply stopped working for no apparent reason. It doesn't appear in the list of the available networks anymore. I can see all my neighbors' networks, but not mine. It's as if it doesn't exist anymore. The internet connection (non-wifi), which goes through the same modem/router, is fine though. I already had a similar problem about one year ago (see here: Wifi network SSID not visible ), just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the Cisco "Magic" software; but this time it's not working. I use a linksys router-modem (WAG320N) which is directly connected (via network cable) to my desktop computer (Windows 7). I have (mainly) two devices that use the wifi network: my phone (Samsung Galaxy Nexus) and an Asus tablet (TF201, aka Transformer Prime). I also resurrected an old laptop computer (Dell, running Windows XP) to test that, and it doesn't see anything either (apart from the 20 other wifi networks, of course ^^). This wifi network was working just fine and has been for about a year. I haven't touched the modem settings so I have no idea what's causing the problem. I tried: making my phone "forget" about my network, hoping it would see it again after that: no luck. re-entering the network informations (SSID/password) manually on my phone: still no luck (says it's not in range) exporting the modem configuration, resetting the modem (factory reset, via modem admin), restarting it, importing the configuration: nope. factory reset, turning it off for 15 minutes, restarting, re-factory reset, and entering the configuration manually: still nothing. Has anybody experienced something similar before? Have you any suggestion to fix that? Thanks in advance. PS: to clear things up, here are the settings of my modem regarding wifi: Basic wireless settings: Configuration: manual Radio Band: 2.4GHz Wireless Network Mode: B/G/N-Mixed SSID: s427 Channel Bandwidth: Wide - 40 MHz Channel Wide Channel: 9 - 2.452GHz Standard Channel: 11 - 2.462GHz SSID Broadcast: Enable Advanced Wireless Settings AP Isolation: Disable Authentication Type: Auto Basic Rate: Default Transmission Rate: Auto N Transmission Rate: Auto CTS Protection Mode: Disable Beacon Interval: 100 DTIM Interval: 1 Fragmentation Threshold: 2346 RTS Threshold: 2346

• Estimating file transfer time over network?

  - by rocko

  I am transferring file from one server to another. So, to estimate the time it would take to transfer some GB's of file over the network, I am pinging to that IP and taking the average time. For ex: i ping to 172.26.26.36 I get the average round trip time to be x ms, since ping send 32 bytes of data each time. I estimate speed of network to be 2*32*8(bits)/x = y Mbps -- multiplication with 2 because its average round trip time. So transferring 5GB of data will take 5000/y seconds Am I correct in my method of estimating time. If you find any mistake or any other good method please share.
