• Linux Mint on VirtualBox has no internet connection

  - by Martin

  Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

• How to clear unshown OSD notifications

  - by Avatar Parto

  I am a webmaster of 2 active websites. Every time I start Thunderbird, it downloads all the new messages from the admin mail addresses of these sites - [email protected], [email protected], [email protected], etc. There are about 20 of them - this includes my personal email accounts. Now, am not always connected to the internet and there arises cases where I need to access already downloaded mails. Thunderbird then tries to connect to the internet, which it can't coz am offline, and then displays about twenty OSD notifications, one after the other, telling me that connection for each email address has failed. That's frustrating and it really eating me up. Am looking for a way, either: 1. To tell Thunderbird NOT to connect to the internet when am offline, or 2. To clear all these notifications after like the first one shows. And if it will help, am using ubuntu 13.04 and Thunderbird 24.0 and I always keep my computer fully updated. Any help is welcome. Thanxs.

So i want you to recommend me some good software to record the screen on a fast way... Thanks a lot. Juan

• Ubuntu Tools for recovering data from damaged USB Flash Drive ~ 10 Gb

  - by PREDA LUCIAN

  I have technical issues with my USB Flash Drive - JetFlash®V15 (TS16GJFV15) It's very critical situation because I can not see the data from it and I should get a way to recover them ASAP. So, in general, I have connected Non-stop that USB Flash Disk at my laptop. Was appear Power surges and when I was coming back, I saw that problem with it. Details regarding JetFlash®V15 (in present): - when I connect it on USP slot, the led is working intermittent and later on remain with constant light. - if I inspect the computer drivers, I found "Generic USB Flash Disk" (when the stick it's connected). - if I inspect "Properties", I can see next details: --- Type: unknown (application/octet-stream) --- Size: unknown --- Volume: unknown --- Accessed: unknown --- Modified: unknown I inspected that stick on 2 different computers (as well in different different USB Ports) and was the same problem, I can not see the content. I was checking with Windows 7 and Ubuntu 10.04 OS, but without success. With both OS was working before this issue. I'll appreciate an answer which will solve the problem, not an answer which will certify the problem. What I have to do, to recover the information form it (nearly 10 Gb)? I'm looking forward to be guided from a technical expert.

• Unrecognized file format .mdb in Microsoft Access -- repair doesn't fix it

  - by user1282159

  So what I have is a file from a staff computer that I believe is an access file b/c its called .mdb, however it does not open! I even tried to follow the repair steps (create a new file and use the "compact and repair" tool. and all I keep getting is "unrecognized file format *.mdb" (replace the * with the filename). I am not even sure it is an access file. I have tried using Office 2007 and office 2010 but neither work. Is there a way to fix this that is not on the Microsoft website? Or to determine whether this is actually an access file and not some other file with the extension renamed? Any help would be appricated, thanks.

• Wireless connection disconnects and reconnects with a Netgear WNA1000

  - by William Berkenkamp

  Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard. And I figure this might help a bit *-network description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: eth0 version: 01 serial: 00:1b:b9:a7:39:a4 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=N/A latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:40 ioport:d800(size=256) memory:feaff000-feafffff memory:feac0000-feadffff *-network description: Wireless interface physical id: 1 bus info: usb@2:1.1 logical name: wlan0 serial: 00:26:f2:8b:fb:38 capabilities: ethernet physical wireless configuration: broadcast=yes driver=carl9170 driverversion=3.2.0-24-generic-pae firmware=1.9.4 ip=10.0.0.36 link=yes multicast=yes wireless=IEEE 802.11bgn I have tried installing WICD and it didn't fix the problem.

• No write access on Windows 2008 workgroup share

  - by Serge - appTranslator

  Hi All, I'm trying to access network shares on my new Windows 2008 server (workgroup) using my server's local admin account. I can read files but not modify them. Permissions (sharing + file system) say: Users = Read only. Admins = Full Control. Even though I connect using my admin account (net use x: \\server\share /user:server\me), I can't write. OTOH, I have another share on the same computer where users have Read AND Write. I can write into that one. What's the problem? Does it have to do with UAC? TIA for your help.

• How to set file associations and explorer options in one go?

  - by jokoon

  This has been itching me for quite a long time. When I come on a new computer with any version of Windows, I need to: un-hide file extensions set explorer default view to list instead of icons set the file extensions like h c cpp so they don't open Visual C++ (which can take up to 20 seconds!) each time I double click on them, opening them with something like Notepad++ instead. Isn't there some program to quickly set thoses options to something I want, like some standalone exe, or some generic registry file I can execute when I come on a new machine? I'm a developer and I can't believe I'm wasting so much time on those &*$%@# things.

• Two users using the same same user profile while not in a domain.

  - by Scott Chamberlain

  I have a windows server 2003 acting as a terminal server, this computer is not a member of any domain. We demo our product on the server by creating a user account. The person logs in uses the demo for a few weeks and when they are done we delete the user account. However every time we do this it creates a new folder in C:\Documents and Settings\. I know with domains you can have many users point at one profile and make it read only so all changes are dumped afterwords, but is there a way to do that when the machine is not on a domain? I would really like it if I didn't have to remote in and clean up the folders every time.

• I'll be setting up a dedicated web server at work soon, my first non hobby server - What should I know?

  - by Rogue Coder

  I've been running my own dedicated server running CentOS and a LAMP stack for 2-3 years now, but it's only been hosting my own websites which aren't super important. However, I will soon be setting up a Linux Webserver and Linux Database Server at work, and I'm wondering what are some important things I should be doing. It's an internal server only, so only people in the company can access it. Should I get a slave server for both of my servers for backups? If I do this, how many backups should I be keeping and how often should those backups be done? Right now on my current server I run a cron job nightly to backup my MySQL databases (Usually 40mb files once compressed), and bi-weekly cron jobs to backup my web root. I just store these files on my local computer via FTP. Also, for an internal server like this, should I look at using LightHTTPD or NginX to increase performance, or will Apache be fine?

• How to create a filesystem mountable by windows in linux?

  - by wcoenen

  I have attached an external USB disk to my debian gnu/linux system. The disk showed up as device /dev/sdc, and I prepared it like this: created a single partition with fdisk /dev/sdc (and some more commands in the interactive session that follows) formatted the partition with mkfs.msdos /dev/sdc1 If I then attach the USB disk to a Windows XP or Vista system, then no new drive becomes available. The disk and its partition show up fine in the disk managment tool under "computer management", but apparently the file system in the partition is not recognized. How do I create a FAT32 file system which can actually be used in windows? edit: I've given up on this and went with a NTFS file system created by windows. In debian lenny this can be mounted read-write but apparently it requires you to install the "ntfs-3g" package and explicitly pass the -t ntfs-3g option to the mount command.

• Can't start firewall or automatic updates in Windows XP

  - by Chris Porter

  On a friends laptop following some viruses infestations there is a problem in starting the Windows firewall. The error is: Could not start the Windows Firewall/Internet Connection Sharing(ICS) service on Local Computer. Error 2: The system cannot find the file specified When attempting to turn on automatic updates in the security centre, the message is: We're sorry. The Security Center could not change your Automatic Updates settings. To try changing these settings yourself, go to System in Control Panel. On the Automtic Updates tab, select Automatic (recommended), and then click OK. All the options under "Automatic Updates" are greyed out. I've tried the suggestions below and many others: http://windowsxp.mvps.org/sharedaccess.htm http://support.Microsoft.com/kb/892199 http://windowsxp.mvps.org/repairwmi.htm I can't do a repair install because the installer doesn't detect existing versions. It's XP pro service pack 3.

• SSH only works after intentionally failed password

  - by pyraz

  So, I'm having a rather weird problem. I have a server, that when I try to SSH into, immediately closes the connection if I type in the correct password on the first attempt. However, if I purposefully enter a wrong password on the first attempt, and then enter a correct password at the second or third prompt, it successfully logs me into the computer. Similarly, when I try to use public key authentication, I get an immediate closed connection. If, however, I enter a wrong password for my key file, followed by another wrong password once it reverts to password authentication, I can successfully log in as long as I provide the correct password at the second or third prompt. The machine is running Red Hat Enterprise Linux Server release 6.2 (Santiago), and is using LDAP and PAM for authentication. Any ideas on where to start debugging this one? Let me know what config files I need to provide and I'll be happy to do so.

• How do I use an API?

  - by GRardB

  Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

• ifconfig can't see USB wireless

  - by Alex

  I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

• SSD I/O extremely slow installing/booting Ubuntu 12.04

  - by Menda

  These are some useful specs: Macbook Pro 7,1 OWC Mercury Extreme Pro 2,5" SATA SSD (120 GB). Has SandForce driver. Ubuntu 12.04 Desktop 32 bits. One 18 GB partition for GNU/Linux and 1.5 GB for SWAP. MD5 for the Ubuntu install CD is OK. I tried to install Ubuntu. It seems that everything is recognized, but there's a big problem: read and writes to the SSD are extremely slow. For example, the install process, which shouldn't take more than 20 minutes, it takes 7 hours. Then, booting up the computer takes about 20 minutes. I checked and the problem is definitely the SSD. Every access to any file is like 10 times slower than normal. I have tried to format the partition as Ext4 and Ext3 with the same problem. Trying to install other distros like Fedora 17, I have a similar problem. There's a "lag" with the SSD, but not so accused as in Ubuntu. Surprisingly, Debian 6.0 installs and works without any problem. Mac OS works pretty good as well in the other partition, so I discard it's an SSD problem. Thanks for your help!

• First request too slow even if I have a load balancer in the back

  - by adrian7

  I have an Apache 2 on Centos + bind with a wordpress website on it (e.g example.com). I have also set up, on another server in a different contry a load balancer (varnish:80 + nginx 127.0.0.1:8080) for it - which task is to server all static content under /wp-content/. Using Simple DNS editor I added an A entry to cdn.example.com pointing to the server's IP. So no extra work from a 2nd dns server. Then using htaccess I redirect all requests to jpg|gif|css|js files to cdn.example.com. That works and all files are saved on the "cdn" server and served right away. My problem is that for the first time I enter on example.com (e.g after restarting the computer or closing the browser) the load time is 1 up to 3 seconds, while any subsequent page loads take only 300 to 600 miliseconds. I know it might be a DNS issue, but I have done a cache check on several websites and cdn.example.com indicates the right IP. Do you have any ideas where I should dig to solve this first-time slowness?

• Need help upgrading MacBookPro3,1 RAM to 4GB.

  - by Fantomas

  My questions are: 1) Where to buy it and what to buy? I have heard that this RAM is generic enough and it does not have to come from Apple. 2) Can I reuse my existing stick(s)? Would I have a single 2GB module, or 2 x 1GB modules? 3) If I have 2GB already, is it a good idea to have one old stick and one new one? Which one is better placed at the top and which one at the bottom? Let me know what questions you have. My computer's info: Hardware Overview: Model Name: MacBook Pro Model Identifier: MacBookPro3,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Memory: 2 GB Bus Speed: 800 MHz Boot ROM Version: MBP31.0070.B07 SMC Version (system): 1.16f11

• What could be wrong with my CD drive and how do you fix it?

  - by Jamie

  My CD drive hasn't worked in about 8 months. I was burning CDs in a hurry and pulled it out because it was taking too long (probably an average amount of time). Im running a laptop (Toshiba Satellite A505-6965) that uses a slot drive. Now my computer doesn't accept CDs. It used to pull them in but it doesn't anymore. Ive heard it make odd noises a few times but thats it. The slot is these spongey things and Ive managed to peek into the drive with a flashlight and theres nothing in the way, really. Could someone explain the mechanics of what happened and if it would be possible to fix it? If itd be possible to fix it through Linux that would be great since I keep getting the BSOD (0x0000007B) and am going to try reinstalling Windows 7. But I can't really do that since I don't have a USB drive larger than 2 GB (Windows is about 4 GB) so Im relying on Linux ATM.

• How to setup wireless radio to network using 2 nics?

  - by CptanPanic

  I am having problems setting up this network, hopefully someone can help me. Laptop <- Wireless Radio <- ... - Wireless Radio <- CPU1( NIC1,NIC2) <- SWITCH <- CPU2 I have a computer with 2 NICs (CPU1). One goes to a wireless radio that connects to a wireless laptop, the other NIC goes to network switch. I can't connect Wireless Radio to switch due to space constraints. All the machines and radios are on same network addresses. I tried using Window's Bridge network which did allow Laptop to reach CPU2, but not CPU1. What is the way to get this to work so all the computers can talk to each other?

• Why does HDTune report better performing drives 2 months after installing them?

  - by Rolnik

  OK, so this is really weird. I ran HDTune on a newly set-up home-built computer and got the following readings from my drives in mid-November. SSD 154 MB/s RAID1 87 RAID0 198 (software installs) RAID0 98 Swap drive Today, in January, I run HDTune (same version) and get these results, in MB/s: SSD 186 RAID1 98 RAID0 241 RAID0 98 (Swap drive) Here are more details that HDTune reports on the SSD drive: HD Tune: OCZ-VERTEX Benchmark Blockquote Transfer Rate Minimum : 135.4 MB/sec Transfer Rate Maximum : 219.4 MB/sec Transfer Rate Average : 185.7 MB/sec Access Time : 0.1 ms Burst Rate : 187.3 MB/sec CPU Usage : -1.0% To get to my question: Why are my hard drives improving in performance? Most of my logical drives are in some form of RAID, except for the SSD. Will this performance ever deteriorate? Note, none of my drives are a hybrid drive that uses some form of SSD to enhance the write/reads on actual platters.

• What is a safe way to dispose of personal info on an old laptop and what to do with said laptop?

  - by MikeN

  I have an old laptop someone gave me that only has 64Megs of RAM on it and runs WIN XP. I wanted to wipe the drive clean by installing Ubuntu Desktop to remove any shred of personal information on it and to make it useful to someone else. But the Ubuntu installer keeps failing because there is not enough RAM. Is there another version of Linux that would easily install on a 64 Megs of RAM system? 2nd part of question, what do I do with this old laptop? It doesn't have a battery anymore and has to be plugged into the wall to run. Assuming I can install a good Linux distro on it, who do I give it to? Salvation Army? I'm looking to just have it be useful to someone or some organization for spare parts or some basic computer usage.
