• What are the major distinctions between PureDarwin and FreeBSD?

  - by ??????? ???????????

  I'm looking to install a different unix on my workstation to acquire some perspective on GNU/Linux and out of curiosity. I have narrowed my options down to these two. The reason for considering PureDarwin is because I have very little experience with Apple's products. So my question is will installing and using PureDarwin give me a closer understanding of OSX than would running FreeBSD? What I have in mind are day to day routines like adding users, installing software and configuring various aspects of the underlying OS. I know that the GUI of OSX would not be available, but that is not a concern. As a secondary, less important question, can I buy OS X in the apple store and run it in a virtual machine or does that violate their EULA?

• Is UEFI more or less vulnerable than Legacy BIOS?

  - by Eric

  Is UEFI more secure than BIOS on a Windows 8.1 machine? Is UEFI vulnerable to malware in ways that Legacy BIOS is not? Is it correct that UEFI can connect to the internet before the OS (or anti-virus program) has loaded? On some boards, UEFI settings can be changed in Windows. Do these things affect PC security? I have read that BIOS on an MBR disc can be vulnerable to 'rootkits' There have been reports that suggest UEFI secure boot may not be infallible. Is UEFI better at defending against malware than BIOS?

• Mirroring of Apps across servers

  - by user1038814

  We wish to host multiple apps across multiple servers. What we are looking for (ideally) is an existing solution which will work. For example, normally to do it we'd follow a route (for failover) like: App is installed on one server along with mysql database App is also installed on a second server. Rsync is used to mirror the files over to the second server and ensure consistency MySQL is installed with a Master-Slave setup. We use a service such as DNS Made Easy which has a DNS failover. If one server goes down it automatically routes traffic to the backup server We have done the above a few times and generally its fine. The issue I have here is that the above is for one app. What I would like to look at is how we can manage for multiple apps and if there is a layer (such as VMWare) that has complete mirroring built in at the OS level? For example how do web hosts currently do it when they ensure that more than one machine is running a bunch of hosted websites. If you were running hosting and you had 200 clients on a server you would want the same clients across 2 or more servers and want everything mirrored. Any advice would be much appreciated.

• RAID 5 heavy IO hard freezes Ubuntu: Why?

  - by Luke has no name

  I have a software RAID 5 partition on LVM in Ubuntu (desktop, actually, but I'm using it as a server). I have been rsyncing a ton of data to it, and the computer was hard freezing, as in I needed to press "Reset". So I thought it was rsync. But I decided I'd try a dd if=/dev/zero of=/path/to/raid5 and sure enough, the computer locked up. Did an identical dd to a JBOD partition on the same machine, and it didn't crash. Assuming a clean RAID5 partition, tri-core processor 2GB of ram, 6GB swap, what could be causing this?

• ubuntu 13.10 liveboot/installer loads dots, then does nothing

  - by user200245

  Problem: When I load an Ubuntu 13.10 (64-bit) live USB / installer on my laptop, the purple Ubuntu screen with the white dots appears, the dots turn orange (indicating its loading), then after a few seconds the screen turns completely black and nothing else happens. I can not install Ubuntu 13.10 on this computer. What I've Tried: I've re-downloaded the .iso file from canonical. I've burned the .iso to the USB using the default linux usb image writer, and the Windows programs YUMI and Linux Live USB Creator; same thing happens each time. Yes, I'm sure my computer is 64 bit. I'm currently running Linux Mint 15 on it, which runs perfectly. It's a Sager NP7330 / Clevo w230st. extra info A few months I installed Ubuntu 13.04 on this machine, which installed perfectly. Normally I'd install that then dist-upgrade to 13.10, HOWEVER this computer is only a few months old and the wireless/network drivers for my network card were not implemented until kernel 3.11 (which comes w ith 13.10). I tried manually downloading kernel 3.11 and installing it (on 13.04), however the wireless card nor ethernet card still did work with Ubuntu 13.04. So my only real hope is to get 13.10 working. Does anyone know what's up with this?

• ubuntu 12.04 will not play DVDs

  - by ayelet

  First off, I'm not just a newbie, I'm clueless! So your answers will need to be in complete idiot language (let's say I'm computer saavy, and I can follow directions,but I've never programmed anything and assume I don't understand any abbreviations. So why am I running linux? b/c windows was driving me nuts!! and my friend convinced me. day-to-day operations, we're doing fine, but when it comes to problems, I've got no clue what I'm doing!) So here's what's going on, my machine is an HP pavilion dv6, my optical drive is a standard cd/dvdrw, when i load an audio cd of any type (burned, official, etc,..) I have no problems, when I pop in a dvd - i get nothing. the dvd icon comes up in my launch tray, when I open VLC player I can find the dvd in the folder... but it won't play. I can watch movies I've downloaded with no problem, I can also watch movies off an external hard drive. The only thing I've tried is removing vlc and reinstalling, and I tried installing a different player (gnome maybe? I don't remember). none of that worked. Again, i can follow directions, but you need to be very specific and don't assume I know anything going in. (I mean, I know basic stuff, but nothing too technical.) PLEASE HELP!!! MY KIDS ARE DRIVING ME CRAZY!!! Thanks!!

• gmail download by POP3 won't download all emails. How to reset all emails to not downloaded so that ALL will download?

  - by Rob

  I want to download emails from gmail using POP3 with Outlook Express. It downloads about 350 or so emails but doesn't download the remainder - there are over 2000 emails. The emails downloaded are not recent. I've tried disabling and re-enabling POP options in the settings in gmail itself but this doesn't fix the issue. Any ideas? Failing that I would use IMAP. I would try to then copy it locally on my machine to the standard POP Inbox folder in Outlook Express so that Express Archiver (a separate program) can then archive each email as a file with meaningful file names (e.g. subject, sender). I want to download email because I archive back it up with project work material it relates to, so it is all in one place.

• Remotely enter encryption key?

  - by Jason Swett

  This might be a really dumb question but here goes, anyway. I just bought a couple servers. I already installed Ubuntu with encrypted LVM on one and I'm planning on doing the same with the other. This means that every time I boot up each of these machines, I have to enter the passphrase. And I'll have to do this every morning because I'll power each machine off each night for security reasons. Here's the problem: I don't have monitors or keyboards for these servers. It seems to me I have two options: Somehow enter the passphrase remotely Buy a KVM switch I doubt #1 is an option but I want to make sure it's not before I buy a KVM. Is it possible to enter the passphrase remotely? AND is it a good idea?

• Shutdown button doesn't work in Windows 8

  - by Yob

  Some time ago I installed Windows 8 64bit ready-to-market version (as a student I had access to it before premiere). What I discovered is that the "shutdown" button doesn't work. When I want to shutdown the computer it simply logs me out. In order to turn off my machine I have to click "restart" and then simply press the poweroff button. I installed some updates but this issue is still not resolved. Is there any way to shutdown the computer in a normal way?

• Windows 7 equivalent of "Add-WindowsFeature"

  - by L.Moser

  I'm wanting to script the "Turn Windows Features On of Off" functionality for my development group so that we'll have a means of ensuring that everyone is running on the same configurations. We are running Windows 7. Is this possible without DISM.exe? It doesn't necessarily have to be scripting. Windows Features is just one of serveral configurations that developers are responsible for modifying personally. It would also be nice to ensure (for example) that IIS and certain services are configured properly on a given developer's machine. If there's a larger scale tool that could give us this functionality, I would be interested in that too.

• Folder vs File Folder - Can I create a folder from the command line?

  - by Tim Gradwell

  If I create a shortcut to a folder and drag the shortcut onto the start menu, then the shortcut on the start menu behaves just like any other shortcut - click it to open the folder in explorer. However, if I drag the folder onto the start menu, then it expands in-situ. If I then copy this shortcut(?) into another location on my machine and compare it to other files/folders, its type appears as "Folder" as opposed to "File Folder" (which is what I get when I choose File-New-Folder. What's the difference between these two types of folder? Can I create one of these folders without dragging onto the start menu? Thanks

• When opening any file in excel, a 1 is added to ther name, and the default is to save a new copy…

  - by Chris

  Ok... I've searched a lot for this, but it's not an easy question to search for! When I open any files (xls, or xlsx) in Excel 2007, excel acts like it's a read only file, essentially creating a new file with the name plus a 1 on the end... Eg. I open NewDoc.xlsx Excel opens it as NewDoc1.xlsx and the save button brings up the save as dialogue in my default folder. Does anyone know how to set it back to allowing me to open, edit and save a document without having to browse to the original document and save over it!? My immediate thought was access permissions, but the file is in a network folder with my user given Full Control, I also tried creating a new file in that folder, and also on my local machine just in case - same result. To make it even stranger, if I browse to the original file using the save as dialogue, it will let me save over the original, without any further prompts.

• Manage a lot of open ssh sessions to servers with id's for hostname

  - by kimausloos

  Lately I'm working a lot with a few open ssh connections to multiple VPS servers. The hostnames of the servers all follow an ID approach and it's becoming very difficult to know on what machine I'm working with. I was wondering if there is a way to put a name I define somewhere as the title of the terminal. So I would, for example, associate IP 123.123.123.123 with webserver-stg. When opening the connection to the IP, webserver-stg would automaticaly be displayed as the name of the session. Of course I'm not able to change code on the VPS servers, so the solution should be client-side.

• How to get the Host value inside ~/.ssh/config

  - by iconoclast

  Within a ~/.ssh/config or ssh_config file, %h will give you the HostName value, but how do you get the Host ("alias") value? Why would I want to do that? Well, here's an example Host some_host_alias HostName 1.2.3.4 User my_user_name PasswordAuthentication no IdentityFile ~/.ssh/some_host_alias.rsa.id LocalCommand some_script.sh %h # <---- this is the critical line If I pass %h to the script, then it uses 1.2.3.4, which fails to give it all the options it needs to connect to that machine. I need to pass some_host_alias, but I can't find the % variable for that. (And: yes! I'm aware of the risk of recursion. That's solved inside the script.) UPDATE: Kenster pointed out that I could just hard-code the Host value as an argument to the script. Of course this will work in the example I gave, but it won't work if I'm using pattern matching for the Host.

• Win Server 2008 R2 - Mapped shared folder hanging?

  - by M-Tech

  I have recently built a windows 2008 server R2 machine. This is purely for file server purposes and is very much a basic build. All windows updates installed and part of domain. I have setup a shared folder on the C:Drive and added permissions for domain users as co-owners. The client machines run XP SP3 and are part of the domain also. We have a few servers running the same setups on a few of our sites but this one is particular crashes users machines (explorer.exe hangs for at least a few mins) when attempting to access the shared folder. I have turned off the option on the network card for power save aswell still no change. Any help with this is very much appreciated and i look forward to hearing from you ;)

• Ubuntu 9.10 Dowload Speed Very Slow

  - by Don

  I'm running Ubuntu 9.10 desktop and I'm new to the Linux world, so bear with me. I'm on a corporate network of 3 T1s shared across 50-60 users. I typically get about 300 KB/sec for downloads, but for whatever reason, the Linux box will start out in that range, then drop to less than 1KB/Sec sometimes. Doesn't seen to matter where I'm downloading from. Right now I'm trying to get Eclipse for PHP and it's running at 3-6KB/sec. Getting the updates for the system will also drop to very slow rates. Our IT person has set up the machine to get the same 10.0.0.x address when it starts, and moved this IP to bypass our Proxy/Firewall going out, so that shouldn't be the issue. Can anyone recommend something I can try to better diagnose the problem. Again, I'm new to the Linux world and the hardware/OS setup side in general (coming form more of a coding background). Thanks for any advice.

• Samba Permissions

  - by Nelson

  I have Samba set up on a Fedora 15 Machine. All looks well except that there's something nagging and I don't know what exactly is causing it. I have a public share on the server which is accessible by everyone and its permissions is set to 777. When one person opens a document under that share and closes it after working, the other person who opens it can't edit or save it because it opens in read only and shows that it's still open on another computer. What might be causing this and how can I resolve this?

• GVim asks for passphrase on every action when using scp

  - by Ashnur

  I want to use my vim config when editing files, but there are at least 5 different servers right now where I have to edit them. Of course I could use console (where I set up ssh-keys and and have a script so it wont asks for passhphrase), but then I have to maintain the vim config on every machine. so I decided to use gvim and browse/edit the remote machines via scp://, but on every action a popup appears asking for the passphrase. this is a ubuntu 10.10 install, with xfce installed later on. i checked in the xfce settings so gnome services should start, but it still won't remember the passphrase.

• TCP Sessions and IP Changes

  - by Kyle Brandt

  What happens to a TCP session when the IP of a client changes? I did a simple test of having netcat listen on a port, and connecting to that port from a client machine. I then changed the IP of the client while that nc session was open and sent some data, no data was received by server after changing the IP. I know they are different layers, but does TCP use IPs for part of how it distinguishes sessions? Does my example not work because of how the application handles it, or is this not working because of something happening at TCP/IP/Ethernet layers? Does this depend on the OS implementation? ( I am most interested in Linux at the moment)

• Where might I be having problems with making web server acessable (XAMPP)

  - by Erx

  I've installed XAMPP and it seems to be working - sort of. It will serve pages if I access it via http://localhost or 127.0.0.1 but not if I use the actual IP address I have. I thought it might be a firewall issue, so I turned off the firewall and the issue still remains. I don't have enough experience to know where to look next, so I thought I might get some advice here. Running on Vista. The error I'm actually getting it "Timed Out". I've had XAMPP running on this machine prior, but I've had to reinstall my OS/new hard drive ... and I can't seem to get it working.

• How does hadoop decide what its nodes hostnames are?

  - by Dan R

  Currently the urls generated by the jobtracker & namenode return either hostnames like bubbles.local or just bubbles. These end up not resolving unless the client machine has specified these in their /etc/hosts file. When I run the hostname command on these machines it returns a hostname complete with the domain (E.G bubbles.example.com) Running a small java test on these machines InetAddress addr = InetAddress.getLocalHost(); byte[] ipAddr = addr.getAddress(); String hostname = addr.getHostName(); System.out.println(hostname); Produces output just like the hostname command. Where else could hadoop be grabbing a hostname to use in its jobtracker / namenode UI? This is occurring in clusters with Hadoop 1.0.3 and 1.0.4-SNAPSHOT from early august. The machines are running CentOS release 5.8 (Final). The generated URLs I'm referring to are like this http://example:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/ or http://example.local:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/

• Hard drive skipped in boot

  - by Yasin

  Good evening. I just installed Ubuntu 12.04 using a USB, but right after the install, after restarting the machine, I get a message asking me to insert a bootable drive. My boot settings in Bios have the hard drive first, then DVD, then USB stick, and I have two systems installed, Windows 7 and Ubuntu 12.04. I suspected the hard drive got somehow disconnected internally, so I checked but everything was in place. I used the live USB to start Ubuntu, and I could see the hard drive and mount whatever partition I wanted. The one that contains the recently installed Ubuntu, looks the same. (It hasn't been deleted or anything). I'm not sure if this is a hardware problem or a loader(grub) problem, because the hard drive is visible. Only it isn't seen by the BIOS. My only means of internet connection is a USB modem, which doesn't work when I'm using the live USB, so I have can't download anything from the internet, in case someone asks. I also reinstalled Ubuntu 12.04, to no avail. This is my second problem with this laptop, and Ubuntu, and it's not even a week old. I hope this one gets solved. Thank you.

• Custom prompt doesn't work on Mac Terminal

  - by mareks

  I like to use a custom prompt (current path in blue) on my unix machine: export PS1='\[\e[0;34m\]\w \$\[\e[m\] ' But when I try to use it on Mac's terminal it doesn't work: it fails to detect the end of the prompt and overwrites the prompt when I type commands. This also happens when I'm inputting a long command where it wraps over the same line instead of starting a new line. I don't understand why this is the case since I use bash on both machines. Any suggestions on how to remedy this?

• Resetting default Input Method in Mac OS 10.6

  - by Tim Visher

  I'm a Dvorak guy. I recently installed a new machine at the inlaws who are not Dvorak people. I stupidly selected Dvorak as my Input Method of choice while installing OS X. Now, all of the users I created default to Dvorak and need to go through the manual process of removing Dvorak as their Input Method of choice and instead choosing U.S. I have no idea how far reaching the implications might be. Could be that any time another user is added they will default to Dvorak. Right now, I'd like to set the default back to U.S. How can I do that? Behaviors I'm looking for include that when the Input Menu is not shown at the Login Screen, U.S. is the keyboard layout. Any future users created should default to U.S. with no Input Menu in the menu bar. Any users created already should have their default layout be U.S. Thanks in advance!

• What is OpenSVC?

  - by sh-beta

  OpenSVC was just ported to the FreeBSD platform. The little blurb in that announcement intrigued me so I went to the OpenSVC website and found this: OpenSVC is a 'service' manager, as in clustered service manager, designed for real-world heterogeneous datacenters and large-scale operations orchestrator (disaster recovery, for example). Services are collections of resources (virtual machine, ip, disk groups, filesystems, file synchronizations, and application launchers). Services can be started, stopped and queried for status, providing a consistent command set for wildly different service integration types. Service configurations, status and logs are pushed to a central database coupled to a web front-end (collector). Services can be administered using the stand-alone GPLv2 software stack deployed on the nodes (nodeware), or through the web-front end. Plus some UML-type graphics. Which is all neat, but I still don't understand: what does it do? Am I just being dense? What's the use case for this system?
