• Using pscp and getting permission denied

  - by Espen

  I'm using pscp to transfer files to a virtual ubuntu server using this command: pscp test.php user@server:/var/www/test.php and I get the error permission denied. If I try to transfer to the folder /home/user/ I have no problems. I guess this has to do with that the user I'm using doesn't have access to the folder /var/www/. When I use SSH I have to use sudo to get access to the /var/www/ path - and I do. Is it possible to specify that pscp should "sudo" transfers to the server so I can get access to the /var/www/ path and actually be able to transfer files to this folder?

• rsync does't work

  I set up a new ec2 ubuntu server and I'm unable to use rsync to push a file up. I can ssh to the machine with my keypair.

• How to connect Android phone to a Wifi network using PPPoE?

  - by Slavo

  I have an ISP at home, which provides me with a PPPoE connection. My router supports that and I've configured it to autoconnect periodically, so I don't have to type my username and password each time. When I connect to the Wireless router from the PC, I have internet and everything works fine. However, when I do so using my Android phone, there's no internet connection on the phone. It connects to the router, but I cannot open any web page. How can I enable internet access from such an ISP on my phone? Is it something in the router setup? The router is Linksys WRT54GL.

• Using a second wifi router as a wireless bridge

  - by Greg-J

  I purchased a D-Link DGL-4500 to replace my aging WRT54G around a year ago, only to find it nowhere near as reliable. It's been collecting dust since. I'm wondering if there is a way to use it as a wireless bridge so I can connect it to my home network and then use it's ethernet ports to provide network access to several devices. Is this something that can be done? If not, are there devices meant for this? Any help would be appreciated.

• Linux Security/Sysadmin Courses in London?

  - by mister k

  Hi, My employer has offered to send me on a couple of training courses and I'm just looking for some recommendations. I'm mainly looking to improve my security and general sysadmin skills. I would like to do something focused on UNIX as I mainly work with Linux boxes (but also a couple of FreeBSD boxes). I don't want to do a study-from-home course, so I would need to find somewhere based in London. It would be great to hear from anyone who has some experience with this kind of course. The courses I've found so far are: www.learningtree.co.uk/courses/uk433.htm www.city.ac.uk/cae/cfa/computing/systems_it/linux.html www.city.ac.uk/cae/cfa/computing/systems_it/unix_tools_ss.html I'm not sure the City University courses are advanced enough as I already have experience... Thanks!

• Running Ubuntu Server from a USB key / thumb drive (being mindful of flash's write limitations)

  - by andybjackson

  Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and a ZFS RAID-Z array for data. I settled on this configuration after trying and regretfully rejecting FreeNAS because the Logitech Media Server (LMS) software isn't available on the AMD64 flavour of this platform and because I think Debian/Ubuntu server is a better future-proof platform. I considered Open Media Vault, but concluded that it isn't quite yet ready for my purposes. That said, FreeNAS does include the option to run itself off a 2GB+ flash device like USB key or thumb drive. Apparently FreeNAS is mindful of the write limitations of flash devices and so creates virtual disks for running the OS, writing only the required configuration information back to flash. This would give me an extra data drive slot. Q: Can Ubuntu Server be configured sensibly to run off a flash device such as a USB key/thumb drive? If so, how? The write limitations of flash should be accounted for.

• Is it conceivable to have millions of lists of data in memory in Python?

  - by Codemonkey

  I have over the last 30 days been developing a Python application that utilizes a MySQL database of information (specifically about Norwegian addresses) to perform address validation and correction. The database contains approximately 2.1 million rows (43 columns) of data and occupies 640MB of disk space. I'm thinking about speed optimizations, and I've got to assume that when validating 10,000+ addresses, each validation running up to 20 queries to the database, networking is a speed bottleneck. I haven't done any measuring or timing yet, and I'm sure there are simpler ways of speed optimizing the application at the moment, but I just want to get the experts' opinions on how realistic it is to load this amount of data into a row-of-rows structure in Python. Also, would it even be any faster? Surely MySQL is optimized for looking up records among vast amounts of data, so how much help would it even be to remove the networking step? Can you imagine any other viable methods of removing the networking step? The location of the MySQL server will vary, as the application might well be run from a laptop at home or at the office, where the server would be local.

• Homegroup and NTFS permissions

  - by bytenik

  I'm running a copy of Windows 7 as a "server" at my home. I have several file shares that I want to make available to specific users only. I've modified the NTFS permissions to only allow these users to access their respective shares. However, while a locally logged on user can access the actual folders just fine, over the network the remote access is authenticating as HomeGroupUser$ rather than the actual user in question, as shown by the Computer Management panel for shares. I do have matching user accounts (i.e. my username locally is abc and a parallel account with username abc and the same password exists on the server machine). I don't want to disable homegroup because there are other shares where homegroup authentication would be desirable, especially for some people where they don't have a parallel account. Is there a way to get the system to authenticate first by matching username, and then by homegroup authentication if there's no matching user?

• assign, not toggle, category

  - by Hemal Pandya

  The Home/Categorize option in ribbon on Outlook 2010 toggles categories. If a group of mails is selected where some of the mails already have the selected category assigned then the action removes the category from those mails and assigns to the rest. I view mails grouped by conversation and would like to repeatedly assign a category to all mails in the group. I can clear all categories before assigning, but that would work only if the mails have only one category assigned. Ideally, I would like to change the behavior of the existing button. If not, a different menu option or shortcut. Is there a way to do either of this?

• Machine only responds to network requests from machines it is pinging

  - by ILikeFood

  I have two machines. WOPR: Ubuntu server edition 10.10 LTS 32 bit Adam Selene: Windows 7 home premium 64 bit / Ubuntu Desktop 10.10 LTS 64 bit I want to be able to SSH from Adam Selene to WOPR, so I connect them to the same network. Here's where things get weird. I cannot connect to WOPR in any way under normal circumstances. But, if WOPR is pinging Adam, then it starts responding to ping requests, HTTP gets, and SSH tunnels. I'm an amateur, and brand new to Ubuntu server, so I suspect there's a misconfiguration somewhere, but there's an off chance it's a bug in the OS. Does anyone know what might cause this behavior? Thanks a lot!

• Getting Synergy+ to work with Windows 7 64bit and Windows XP 32bit?

  - by john crisp

  My Windows XP box is Dell 4550 dimension. Windows 7 box is Home Premium. Synergy + installs fine on the Windows 7box, but using Windows xp as the client, it won't work? Do I need to disconnect the vga connection from my monitor and control entirely from the win7 dvi connection? In setting up ( links ) on Windows 7 as the server, I have NO way of inputing info? The setup on the Windows xp box is simple and does so OK, but I can't connect to the Windows xp box! It must be the vga connection on the Windows XP box. In order to use both machines, I have to turn one off and the other on. Hence-the VGA is needed on Windows XP. Any info/help most appreciated.

• Strange sound from Laptop, Microphone, Speakers or Soundcard?

  - by David Schilling

  I have recently purchased a second hand computer. There didn't seem to be anything wrong with it on purchasing, however recently I have noticed a small issue. Any time I play sound or listen through my headphones, I can hear what seems to be the CPU working (ie when beginning a new task, there is a small crackling). Also if I tap my laptop I can hear the sound louder, as if it is being picked up by the mic and then playing that sound in real time through the speakers or headphones. I have tried reading other topics but cannot find an answer to this question. These are the specs I am running on; Windows 7 Home Premium 32bit Pentium Dual Core CPU T4300 @ 2.10Ghz 2.10Ghz I hope someone can help me with this issue, it would be much appreciated.

• Dual boot on Hp Envy Ultrabook

  - by phodu_insaan

  I just bought a HP Envy ultrabook 1002TX. It comes with a Win7 Home basic and a 32GB SSD + 500GB HDD. I started to install ubuntu and in doing so went and deleted all the partitions on my HDD and recreated them the way I wanted. Then when I tried to install ubuntu it didn't recognize my HDD. To solve this i typed dmraid -E -r /dev/sdX where the 'X' was my SSD drive. After this ubuntu can install but windows for some reason does not install. Also the Intel Caching feature is lost and SSD is just sitting and doing nothing. I want to know how to solve this problem. Ideeally I would like to use the SSD for caching, either in windows or ubuntu. How do I get the SSD back to working as an Intel rapid cache? How do I get windows to install properly? It tell me that windows is unable to configure itself to my hardware, and my PC came with windows pre-installed so this is not possible. Sorry for the long question and thanks for your answers! PS: At one time when I booted I pressed Ctrl+i and went to the intel rapid cache menu. I think i screwed up something in here, because only after this the rapid cache stopped working, and each time I booted the PC thought the BIOS was my primary disk.

• How to fix this navigation issue in my site?

  - by David

  First off I use webs.com for the creation of my site. I have a very basic layout. List of links of the left and content on the right with a heading up top. Now in my list of links every link is an article that I wrote, I have about 25 links going down the left hand side of my site. Problem is when I try out new themes that support horizontal navigation as opposed to vertical navigation I get either a messy overflow of links Or a link called "more" which lists the rest of the articles in a drop down-list across my site. What I wish I had was a simple horizontal navigation like" "home, about, articles" and when the user clicks on articles it would then bring them to a page containing all my articles there. I would prefer it to be in a table like display. That way is not a long list. Anyways any ideas on how I can fix this issue im having? Please let me know if you need more information.

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by ajit.george

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues? Thanks in advance.

• Is it my motherboard?

  - by jarodrussell

  Early this week my home server (a Linux machine) threw a kernel panic. Yesterday is happened a couple of times. Then all of a sudden, when I plugged a USB stick in to run a memory test, the monitor stopped coming on. Now whenever I turn it on, the system gets power...I heard the drives spin, I see the processor fan spin, and the hard drive light comes on...but nothing happens. I put a video card in the AGP slot, but still nothing. The light on the power button that usually comes on stopped coming on. I took the memory out to see if it would beep, but nothing beeped. It's like it's getting power, but it's not coming on. Does this sound like a motherboard problem to anyone else? I think it is, but a second opinion would be greatly appreciated. Thanks.

• Ubuntu 12.04 and Nvidia GTX 550 Ti

  - by Jim

  OK I'm currently trying to install Ubuntu x64 Server 12.04 onto the following machine: Intel Core i5-2320 3.0GHz LGA1155 6MB 8 GB DDR3 RAM, Gigabyte Z68P-DS3 S1155 Intel Z68 DDR3 ATX M/B, OCZ 60 GB SSD, 3x Samsung 2TB drives in a RAID 5 array (via M/B) Now what I think is causing the issue is the following: EVGA GeForce GTX 550 Ti 951MHz 1GB PCI-Express HDMI FPB As the server CD works in text mode I haven't had a problem with actually installing Ubuntu. Partioned with: 1GB /boot SSD, 59GB / SSD, 10GB swap RAID5, ~4TB /home RAID5 On a straight boot, you briefly see the GRUB menu, followed by a blank screen. The keyboard and mouse blink as they are initialised but no sign of life from the screen. Followed by a bit of research (otherwise known as google) ... Booted in quiet splash nomodeset Now I have a fully working linux distro at the command prompt. I then proceed to try and update the nvidia drivers with apt-get (after updating repositories etc) and rebooting. Still the same problem. I also tried reinstalling from the CD and installing said drivers in the install process before GRUB was installed, still the same symptoms. Does anybody have any solutions? I'm at my wits end here, I bought this machine to be a linux server / tinkering machine and have just spent 4-5 hours trying to just get a basic install working.

• Oracle Solutions supporting ICAM deployments

  - by user12604761

  The ICAM architecture has become the predominant security architecture for government organizations.  A growing number of federal, state, and local organizations are in various stages of using Oracle ICAM solutions.  The relevance of ICAM has clearly extended beyond the Federal ICAM mandates to any government program that must enable standards based interoperability like health exchanges and public safety.  The state government endorsed version of ICAM was just released with the NASCIO SICAM Roadmap. ICAM solutions require an integrated security architecture.  The major new release in August of Oracle Identity Management 11gR2 focuses on a platform approach to identity management.  This makes it easier for government organizations to acquire and implement a comprehensive ICAM solution, rather than individual products.  The following analysts reports describe the value of the Oracle Solutions: According to The Aberdeen Group:  “Organizations can save up to 48% deploying a platform of  (identity management) solutions when compared to deploying point solutions” IDC Product Flash, July 2012:  “Oracle may have hit the home run grand slam in identity management recently with the announcement of Oracle Identity Management 11g R2." For additional information on the Oracle ICAM solutions, attend the Webcast on October 10, 2012:  ICAM Framework for Enabling Agile, Service Delivery. Visit the Oracle Secure Government Resource Center for information on enterprise security solutions that help government safeguard information, resources and networks.

• Git for Application Settings

  - by devians

  I use a lot of tools at work and at home, and im constantly tweaking them in one location or the other. It's somewhat common practice for people to use Git to version their .vim, .vimrc, and other . files, since you can host your config files on github and have the share-ability and all the other advantages that implies. Being able to version and branch my configs sounds like a grand idea, since I'm always messing about with them. I'd like to discuss the best practice for doing this on a slightly wider scope. How would you implement it? Have your configfiles repo in ~/Library/Configs or similar, and symlink the appropriate files? How to handle preference files for Applications, ie iTerm2. These files are recreated every time, so you'd have to symlink 'backwards' and put a link in the repo? rather than symlinking to the repo, since it would just delete the symlink.

• Switching DVI socket

  - by lurscher

  I have Ubuntu 10.10 x86_64 with Nvidia 9800 gt and Nvidia driver version 270.41.06 My video card has two DVI sockets, but I only use the single monitor configuration. Now, I think the main DVI socket might be busted, so I want to try to enable the other as the main one, however, I don't know how to achieve that. I tried just plugging the monitor in that socket but it won't auto-detect it (it would have been way too easy to just work).
