  • Good way to backup code projects

    - by rkmax
    I work as a developer, and I have many projects for most of them use GIT for versioning the code, I have some projects that are not code such as interfaces sketches, idea, etc.. currently I have a disorder with the backups before Dejadup used, but the downside comes when I want to restore my backups from Windows. Periodically change of operating system (Windows or Linux). my question is which is better, copy each folder (project) directly to my external disk or create a repository (git - bare init) for each project I need or should do?

  • Disable Crossfire on an ATI HD 5970

    - by cdecker
    I'm trying to create a computation cluster using ATI GPUs. The problem is that I have to disable Crossfire in order to get maximum performance out of the ATI Radeon HD 5970 I bought to get started, but no matter what I do I can't disable it. The problem is that I'd like to run an OpenCL application on the two cores in parallel, but right now they just interfere with each other. Any idea on how to do so under Ubuntu Linux, with ATI Catalyst 10.10?

    - by RadiantHex
    Hi folks, it would be immensly helpful if someone could indicate me how to compile libevent http://monkey.org/~provos/libevent/ on Windows 7. I usually use compile source code on Linux distributions, as executable binaries are usually always available for Windows. Help would be great.

  • How to restore a VirtualBox image given the .vdi file

    - by Ramon Tayag
    Background I have VirtualBox on Linux and recently the drive with the system files failed on me. I'm able to use the Live CD to view the files of the storage drive, and through this, I can copy my data files to another computer while I work on this one. How do I load the .vdi in another computer (or in this case, the fresh install of Ubuntu)? I see many samples online of how to export it, but it assumes the host is currently working. Thanks!

  • Setting up a fileserver, some questions?

    - by Tanax
    Recently I've become very interested in setting up a fileserver, mostly for home usage but also because of the fact that I live in 2 places, I need to be able to access my files from both homes. I have already done some research into this but I am unclear about some things. My requirements are the following; Needs to work on both Mac and PC(only using Windows atm on PC but could be good if it supports more OS's to make it futureproof in case I need Linux or something else) Need to be able to set up a folder/drive/network space to act as a link to a certain folder on the fileserver All files should only be stored on the fileserver, e.g. no "shared" folders like in Dropbox where files are stored on the client computer Would prefer it if folders are password protected or that I can somehow specify what users can access the fileserver's shares Fileserver's OS most likely have to be Windows due to other factors outside of being just a fileserver I've already kinda figured out that I will need to set up a VPN so that I can access my fileserver from outside the local network. Probably going to use OpenVPN. Question 1: How would I go about to set up a VPN server so that I can connect to my local network at the fileserver's location? I know that since I'm on a dynamic IP I will have to get some sort of dynamic DNS server - I've already checked into this and I'm fairly sure I know how to fix that. I also know that I will have to forward the port OpenVPN uses in my router. Question 2: How would I actually share the folders on the fileserver so that I can access them on my other computers? I've researched into Samba but I'm uncertain if it needs to be run on a Linux OS. I know that the clients connecting to it can be Windows for example but can the Samba "server" be run on Windows? Also it appears that Samba shares a folder, meaning it works like Dropbox - I don't want that. So how would I share a folder in that case to make it work like I want it to? Sorry for the incredibly long question, I tried to structure it the best I could for easier read. Thanks in advance!

  • mounting VMDK images on opensolaris

    - by Bjorn Harpe
    I know that VMware ships a vmware-mount utility with its server 2 packages on Linux that allow you to mount a VMDK outside a vm and treat it as a normal filesystem mounted on the given mountpoint. Is there a method for accomplishing something similar in OpenSolaris that does not require converting to a raw image and then back?

  • VM image including ready-to-use Kerberos server?

    - by Nicolas Raoul
    I implemented client-side Kerberos support to an open source software, and I want to test it. I don't have a Kerberos network at home and unfortunately don't have the skills/time to reliably set up one. Is there a Virtual Machine image that I could fire up, and that would include a properly working Kerberos environment, so that I can test my client app? (freely downloadable Linux/Microsoft/anything all acceptable)

    Hi, I am running the site at www.euroworker.no, it's a linux server and the site has a backend editor. It's a smarty/php site, and when I try to update a few of the .tpl's (two or three) they don't update. I have tried uploading through FTP and that doesn't work either. I have no knowledge of how servers work or anything, please help? It runs on the livecart system. Thanks!

  • Setting up a GIt server

    - by lindenb
    Hi all, My team is working with several RedHat linux servers and we'd like to synchronize our sources from one server to another (for several distinct projects). I'd like to set-up a git-server as a version control; however I'm new to git and I'm confused by the terms ('server', "daemon', 'repository', etc...). Moreover we're working behind a firewall. Can anyone point me to a link about how to setup a git server ? Thanks. Pierre

  • In search of a network file system with extended caching to speed up file access

    - by Brecht Machiels
    I'm running a small home server that stores my documents. The disks in this server are in a RAID 1 configuration (using Linux md) and it's also periodically being backup up to an external hard drive to make sure I don't lose them. However, I'm always accessing the files from other computers on the home network using an SMB share, and this results in a considerable speed penalty (especially when connected over WLAN). This is quite annoying when editing large files, such as digital camera RAWs, for example. I've been looking for a solution to this problem. It would have to offer some kind of local caching to speed up the file access. The client would preferably not keep a copy of all data on the server, as it consists of a very large collection of photographs, most of which I will not access frequently. Instead, it should only cache the accessed files and sync the changes back in the background. Ideally, it would also do some smart read-ahead (cache the files that are in the same directory as the currently opened file, for examples), but I suppose that's asking a bit much. Synchronization should be automatic (on file change). Conflicting file changes (at the same time on different clients) are unlikely to happen in my use case, but I would prefer if they are handled properly (notification to the user). I've come across the following options, so far: something similar to Dropbox. iFolder seems to be the only thing that comes close, but its reputation (stability) and requirements put me off. A distributed file system such as OpenAFS. I'm not sure this will speed up file access. It is probably overkill for what I need. Maybe NFS or even Samba offer these possibilities. I read a bit about Windows' Offline Files, but its operation seems limited (at least on Windows XP). As this is just for personal use, I'm not willing to spend a lot of money. A free solution would be preferred. Also, the server needs to run on Linux, and I need a client for at least Windows.

  • IPSEC site-to-site Openswan to Cisco ASA

    I recieved a list of commands that were run on the right side of the VPN tunnel which is where the Cisco ASA resides. On my side, I have a linux based firewall running debian with openswan installed. I am having an issue with getting to Phase 2 of the VPN negotiation.

Also, I read a few artilcle where configs contained the interface="ipsec0=eth0", is this an interface that I have to create on the linux debian firewall on my side? Appreciate your time to look at this.

  • Font Substitution - How Does It Work?

    - by Hutch
    Let's say I open Outlook and compose an email and choose a totally random font and hit send. Let's assume I have Outlook set to send in HTML format, and my mail server sends HTML and the recipients server receives HTML, and their client displays HTML etc. However, let's assume their PC doesn't have the font I chose installed (could be Windows, Mac, Linux, anything). What happens next with regards to how it chooses a font to display the message?

  • What's the fastest filesystem for developer builds?

    - by Dan Fabulich
    I'm putting together a Linux box that will act as a continuous integration build server; we'll mostly build Java stuff, but I think this question applies to any compiled language. What filesystem and configuration settings should I use? (For example, I know I won't need atime for this!) The build server will spend a lot of time reading and writing small files, and scanning directories to see which files have been modified.

(I have 3 Linux Kernel versions right now (that I can see and select from Grub menu), and I think I don't need all of them since I always use the latest Kernel).
