• Setting up a home server - what to use? (ZFS vs btrfs, BSD vs Linux, misc other requirements)

  - by monch1962

  I need to get all our home content off individual machines and onto a central server. What I'd like to have is the metaphorical "server under the stairs". Stuff we need: expandable storage. I want to be able to add extra disc as we go along, with minimal maintenance required. Currently we've got about 3Tb of files we need to host, and that's likely to grow by another Tb every 6-12 months based on recent history. I need to be able to add additional disc with minimal pain needs to store all the media (i.e. photos, video, music) we have, and run services to serve the various devices we have in the house to playback (e.g. DAAP so we can play stuff through iTunes, ccxstream so we can play stuff over XBMC). DAAP and ccxstream are needed now, but we also need to support new standards as they emerge (so a closed-box solution isn't going to work) RAID 5, or something broadly equivalent (e.g. RAID-Z) BitTorrent client ssh, NFS, Samba access snapshot capability (as in ZFS), so we can snapshot individual file systems regularly and rollback when my kids delete their school assignments the day before they're due... ability to recover quickly from power outages (it's not unusual for us to have power outages that last longer than our UPS' batteries) FOSS software a modern distributed version control system running on the box, such as Mercurial Stuff I'd like to have on the server, but can live without: PVR capability, so I could record TV to the box Web server. We currently run a small Web server on a very old box, and I'd ideally like to turn the old box off and move the content to the new server just to save some electricity Nagios + mrtg I've been looking at using a EEE Box as the server, primarily because I can get them cheap and they don't consume much power. The choice of OS and file system is more difficult, from what I've found: I've got most experience with various Linux distros, but am happy to use another Unix FreeBSD and OpenSolaris seem to be the best choices for hosting ZFS OpenSolaris' hardware support is nowhere near as good as e.g. Ubuntu btrfs, while looking very good, doesn't seem ready for prime-time yet ZFS doesn't let you (easily?) add new discs to a RAID5 or RAID-Z reading around, it seems that ZFS is a bit short of tools for recovering lost data At the moment, I'm leaning towards running FreeNAS+ZFS, but I'm concerned about the requirement to be able to add new disc on a fairly regular basis to an existing RAID-Z. Can anyone provide some recommendations, or share experiences? Thanks in advance

• Why is my eth0 getting a dynamic ip when it is configured to be static?

  - by sdek

  For some reason our office linux box is being assigned an ip address via dhcp and I don't know why. What is confusing to me is that when I check system-config-network it shows that my eth0 is setup to be a static ip address. And /etc/sysconfig/network-scripts/ifcfg-eth0 also shows it is setup to be a static ip, yet it is getting a different ip address than the one specified in the ifcfg-eth0. Let me know if you have any suggestions on or ideas on where I can look next. Here are a few details that might help you figure out what an idiot I am :) Fedora 11 Router in front of this box is running dhcp, starting at 10.42.1.100 This box is configured to be 10.42.1.50 (at least I think it is!), subnet 255.255.255.0 (which is same as the router's lan subnet) Instead of having the static IP, this box is getting assigned 10.42.1.100. Here are the ifcfg-eth0 details DEVICE=eth0 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet USERCTL=no NM_CONTROLLED=no NETMASK=255.255.255.0 IPADDR=10.42.1.50 GATEWAY=10.42.1.1

• install php on server08 manaully

  - by justSteve

  Looking to install php on a 08 box already holding iis/sql box. I've tried the webinstaller a couple times but the installer locks before completion or managing to echo any sort of error message. Before hunting down a manual install how-to i wonder if the box is trying to tell me something i should be paying attention to. PHP running alongside IIS _must be supported or one would expect that error message to be kinda high on the list. any gochas to beware of? thx

• OpenVPN IPV6 Tunnel Radvd

  - by Arenstar

  Hello.. I have an interesting question regarding ipv6 + openvpn.. My Version is OpenVPN 2.1.1 i have been given a native /64 ipv6 network ( for this example 2001:acb:132:acb::/64 ) The plan was/is, route this block through openvpn and into an office ( for testing purposes ) Soo to explain.. I have a Centos Box as the first linux "router" in a datacenter & a Ubuntu box as the second linux "router" in the office I have created a simple point-to-point tunnel using tun ( based off ipv4 address to start the tunnel ) I have assigned to Centos /sbin/ip addr add fed1::1/128 dev eth0 /sbin/ip addr add fed2::2/128 dev tun0 /sbin/ip route add 2001:acb:132:acb::/64 dev tun0 ## ipv6 Block down the tunnel /sbin/ip route add ::/0 dev eth0 ## Default out to Gateway I have assigned to Ubuntu /sbin/ip addr add fed1::3/128 dev tun0 /sbin/ip addr add fed1::4/128 dev eth0 /sbin/ip route add 2001:acb:132:acb::/64 dev eth0 ## ipv6 Block down to eth0 /sbin/ip route add ::/0 dev tun0 ## Default up the tunnel I have also included on both servers.. sysctl -w net.inet6.ip6.forwarding=1 Looks Good... right??? Wrong.. :( I am not able to ping fed1::1 from fed1::4 (Ubuntu) (can ping :4,:3,:2) However, i can ping fed1::1 fed1::2 from :3 ?????? ( very strange ) I am able to access the internet from any ipv6 interface on the Centos Box but clearly not from the Ubuntu box.. Further, i will eventually run radvd on the Ubuntu box eth0, and autoconf the network with ipv6 address's Anyone with some advice / tips to help me out.. ??? Cheers

• Can't connect to MySQL on CentOS 5 Error 13 - Permission Denied

  - by abszero

  Ok, I have an install of CentOS 5 running as a GuestOS in VirtualBox. The network card for the Cent box is bridged with that of my host OS so that the boxes can see each other. Cent has an IP of 192.168.1.108 and my Host box has an IP of .104. Everything, with regard to networking, seems to be working properly as I can access the Drupal install that is on the Cent box from a web browser on my host box by navigating to http://192.168.1.108 however when I try to configure the database for Drupal through the Drupal install interface I am getting the Can't connect to MySQL error. First I thought this might of been a Firewall issue so I stopped iptables but that had no effect. I thought maybe the user I had setup did not have access to the server so I tried root and that did not work. Searching on the net said that I needed to provide a bind-address parameter to my.cnf so I did that with no change. (As a side note the length of my my.cnf file was MUCH shorter than the ones presented online. In fact under mysqld all I have are datadir, socket, user, and bind-address. Is this normal or should the file be more verbose?) After a few hours of messing with permissions and such I tried using 'localhost' as the value for the database server, from my HOST OS, and the Drupal install kicked off without a problem. So while my issue is resolved I am curious as to why 'localhost' works and why 192.168.1.108 did not? Is there something i need to do to specifically access the MySQL box via the aforementioned IP? Thanks.

• Best practice Raid groups for EqualLogic PS6510X

  - by 20th Century Boy

  We are thinking about purchasing 4 x EqualLogic PS6510X SANs (the Sumo boxes). Each has 48 x 600GB 10k SAS drives. They will be stacked to form a logical pool of storage (all in the same location). I understand that when you create a RAID group its done on a "per box" basis. So one box could be Raid 50, another Raid 10 etc. My question is, should I make one box a "performance" box ie Raid 10, and the other boxes "standard" ie Raid50? How do people configure their EQL arrays in the real world?

• How to type a small fraction in Word 2007 equation editor?

  - by Timwi

  In Word 2007’s equation editor, I can enter “1/2” and I will get a properly formatted fraction. However, there is another kind of fraction that uses a smaller font size. How do I type that one using the keyboard alone? I notice that if I switch to linear mode, I get a small box displayed: Using the clipboard, I find that this is the same box (U+25A1) that I also get if I type “\box”. Despite, typing “\box(1/2)” still turns into a normal-size fraction and not the small fraction. How do I type the small fraction?

• Linksys EA3500 : use WAN port as WAN + LAN possible?

  - by Dough

  I'm waiting for deliver of a Linksys EA3500 router. I was wondering if it was possible to get the WAN port act as normal WAN port (Internet IP) + LAN switch ? My problem is that my Internet box is in a room with NAS and PC, and the router will be in another room with TV, PS3 and PC. The Internet box have a 4 port Gigabit switch so one cable will plug from there to the router's WAN in the other room. The router will get the Internet IP from the Internet box, but will it be possible to have private network through this link too ? I could have a first network between the Internet box and the router, and another network form router and devices but that will do double NAT for nothing... Thanks for reading me and your help !

• NIC: Changing Link Speed & Duplex to Full Duplex Is Drastically Slower

  - by rism

  I have an old Win Xp box with a 100 PRO/100 VE NIC and connecting to a Win 7 box with gigabit NIC via an ASUS gigabit router and peer to peer. I was getting 76% network utilisation on the XP machine using AUTO as the value for Link Speed and Duplex which is fine. But I decided to see what would happen if i selected Full Duplex 100Mbps on the XP box. I thought at worst it would be as good as auto detect since the Win 7 box it's transferring to is faster. Instead network utilisation dropped to 0.12% (as in a 10th of a percent) and the transfers just timed out. No biggie to reverse back to Auto but my question is why is full duplex such a dog? Im not "stuck" but just dont understand. There are only 2 machines here connecting through a router so i cant see how that would cause alot of collisions etc (if thats the problem).

• how to run an AFS file server on a specific ethernet card (in Debian)

  - by listboss

  I have a linux box running Debian server with minimal number of packages (so no GUI for network management). The box has two ethernet cards, one of which (eth0) is connected to a Mac OSX computer using a cross-cable. I can bring up eth0 and assign a static ip (10.10.11.16) to it. This way I can ssh to the box through the cross-cable. This is what I run on Linux box: ifconfig eth0 10.10.11.16 netmask 255.255.255.0 up I also installed/started a file server (AFS) on Debian. So far, the file server can only be accessed through eth1 which is exposed to my home LAN and www. My goal is to set up the file server so that it's only visible through eth0. Is this possible? and if yes, how can I do it?

• Why is Apache htdigest authentication failing in IE10 on Windows 8?

  - by Kevin Fodness

  One of our developers reported that for the past week or two, the htdigest authentication that we have set up on our test sites in Apache is not working in IE10 on Windows 8. It's fine on IE10 on Windows 7, and it's fine on Chrome on Windows 8. The specific behavior is: Navigate to site with htdigest authentication enabled, username and password form pops up, enter correct username and password, and the username and password box pops up again. Potentially useful information: All patches applied on Windows 8 box No additional software on Windows 8 box other than Outlook 2013 and a browser test suite (Chrome, Firefox, Opera, Chrome Canary, Opera Next) Win8 running in a virtual machine on Xen Same behavior can be replicated on Win8/IE10 on Browserstack.com Server running Ubuntu 10.10 with Apache 2.2.16 This feels like a patch was applied to the Windows box that broke digest authentication for IE10 on Win8 (box configured for automatic updates). However, without knowing a specific date I can't necessarily nail this down. Has anyone else experienced this problem? EDIT: This problem only happens in the "Metro" interface, not when running IE10 in desktop mode. As of a few weeks ago, it worked fine even in the "Metro" interface.

• Have Ubuntu auto-connect to wireless AP without logging in

  - by dragonmantank

  We have an ubuntu box set up to do some monitoring but due to the placement are unable to run CAT5 to the box itself. I have an Atheros PCI card that works great as long as someone is logged into Gnome and it doesn't disconnect from the AP during that time. Is there a way to have Ubuntu connect to the AP during boot, and always reconnect if it finds a signal from a specified AP? The box would have a static IP and only connecting to a specific AP using WEP.

• Volume Shadow Copy Remotely?

  - by Wringley

  I'm currently running a Microsoft Server 2008 R2 box and want to utilize Volume Shadow Copy but my development machine doesn't have enough hard drive space for 30 days worth of copies, which is what I am aiming for and currently only have 5 days of backups. I have another Windows XP box and I was wondering if it was possible to remotely store the shadow copy images in my remote XP box. If it isn't possible with the built in Volume Shadow Copy, is there an open source alternative that I can utilize that has the same or similar functionality?

• Routing Traffic on Ubuntu to give Raspberry PI Internet Access

  - by Scruffers

  I'm hoping someone can point me in the right direction for setting up my Linux (Ubuntu 12.04) box to route traffic from eth0 to wlan0. I'll try and explain the problem I am trying to solve: I currently have two separate networks: [RaspberryPi/eth0] 192.168.2.2 / 255.255.255.0 ^ | v [Ubuntu/eth0] 192.168.2.1 / 255.255.255.0 And: [Ubuntu/wlan0] 192.168.1.100 / 255.255.255.0 ^ | v [ADSL router] 192.168.1.1 / 255.255.255.0 So currently if I want to access the RaspberryPI I can SSH from the Ubuntu box to the PI. And if I want to use the Internet, I have full access from the Ubuntu box, but nothing from the RaspberryPI - the two networks are partitioned. What I would like to do is configure things so that the RaspberryPI has Internet access via the Ubuntu box and out to the Internet. I tried to create a bridge, but got the message "wlan0: operation not supported" (wireless chipset is Ralink RT3062). I'm sure giving the Raspberry PI Internet access should be easy to do in this configuration, but I am a bit lost - can someone point me in the right direction please?

• One EC2 source with distributed varnish machines

  - by Elad Lachmi

  I have a web site hosted in an EC2 instance (2008 r2 + iis7.5 + sql server). I put one linux box running RHEL with varnish. After some configuration trail and error, I found a configuration that works. Now I want to duplicate the varnish boxes to other availability zones, but continue to pull the pages from the original windows box. It is my understanding that I can put the varnish boxes in different zones and pull from the windows box via it's external IP. But what do I need to do in order for each user to receive content from the box physically closest to them? Is this even possible? Thank you!

• Need Help Scoping a Server to use for study (MCITP Ent Admin + SharePoint 2010)

  - by AVFamily76

  i need to study for mcitp, but i also need to study for sharepoint 2010 i have a poweredge 1850 with two single-core CPUs + two 73G drives - it kills me on electricity, so don't want to use it, and it won't do VT, but it could be one of three boxes for a lab that's cheap, but will cost a lot on electricity i was thinking . . . OPTION #1 Opteron 4170 HE (50 watt chip), 6-core, only two-bills ($200), but the board's are $250, so that's an $800 box, then get another box to dual-boot Win7/Hyper-V on the cheap...? OPTION #2 Used Quad - but how many VM's that are really banging away could it run at same time? (Server 2008r2, SQL 2008r2, Search Server) OPTION #3 Study from books and just get one box that can run two VM's at same time, even if slowly. the last time i had and used a home lab was five years ago when i had a DC, SQL, Exchange and business app box, that's where i got my server skills was just banging on it for four years, but didn't read any books, so now i have to get certified and know the material, and just am not sure how much attention i should pay to the box i use versus the studying time and reading. sorry it's a subjective question, and am obviously open to all sorts of abuse here, but hope you can tell me also how many VM's i can run at the same time given what they'll be doing (SQL and SharePoint FAST search server are resource hungry) thanks!

• Use Excel Table Column in ComboBox Input Range property

  - by V7L

  I asked this in StackOverflow and was redirected here. Apologies for redundancy. I have an Excel worksheet with a combo box on Sheet1 that is populated via its Input Range property from a Dynamic Named Range on Sheet2. It works fine and no VBA is required. My data on Sheet2 is actually in an Excel Table (all data is in the XLS file, no external data sources). For clarity, I wanted to use a structured table reference for the combo box's Input Range, but cannot seem to find a syntax that works, e.g. myTable[[#Data],[myColumn3]] I cannot find any indications that the combo box WILL accept structured table references, though I cannot see why it wouldn't. So, two part question: 1. Is is possible to use a table column reference in the combo box input range property (not using VBA) and 2. HOW?

• Backup files from Linux client to Windows Server

  - by Andrew

  I'm trying to backup my files from my Linux box to my Windows Server 2008 as a push, and when I delete them from my Linux box, they remain on my Windows Server. I've found lots of sources that are similar, but most results were from Windows to Linux. I managed to find slightly more similar cases like Using rsync and cygwin to Sync Files from a Linux Server to a Windows Notebook PC, and rsync from Windows PC to remote Linux server, with the most similar being a backup from Linux to Windows Server, but through a pull from the Windows Server. Initially, I used Unison because I thought having the 2-way capability would come in handy, and I would just have to set some configurations to make it 1-way. Unfortunately, I couldn't find the right configuration, and only managed to synchronize using the command unison "profile" -ui text -auto -silent. When I deleted the files on my Linux box, the files in the Server got deleted too, which of course, isn't what I want. When I tried to find any options for Unison, I only discovered the -force option, which didn't help, since what I wanted was an incremental update to the Server. I found out I could achieve this from using rsync and the -a option (archive), which would keep adding files even if I deleted them from my Linux box. I installed Cygwin on my Windows Server, configured an SSH daemon, but I can't seem to get it working. I've also already configured Windows Firewall to open port 22 (both inbound and outbound). I used the following command from my Linux box: rsync -avrzn /folder/to/be/backed/up/ [email protected]:/cygdrive/c/place/to/store/backed/up/files (a - archive, v - verbose, r - recurse into subdirectories, z - compress, n - dryrun) but it just won't work. Can anyone help me out? I don't mind using either Unison or rsync, as long as it achieves what I want.

• Windows Server 2008 constantly spamming external IP's on outbound TCP port 445

  - by RSXAdmin

  Hi Server Fault, I have a Windows Server 2008 box running as a Domain Controller. I have noticed in my Cisco ASA firewall logs that this box is continuously sending out (like a thousand requests a second) requests on TCP port 445 to external hosts. I have made an effort to deny this outbound traffic from getting on the internet (using the ASA), however I would like these requests to stop from even occurring at all. I have tried disabling TCP/IP over NetBIOS. I have even turned on Windows Advanced Firewall on the box itself to block outbound 445 but the ASA still detects this particular traffic hitting it. I have other DC's and similar type boxes which are not behaving the same way as this box. Is this normal? Is there a way to stop this spamming? Have I been infected? Thank you universe.

However, every few weeks or so, the connection or the mount point seems to go dead or hang, such that any process that tries to access the mount point gets stuck in D state (disk, or I/O wait). These processes become impervious to TERM and KILL signals. Disconnecting and reconnecting the Windows box from the network does not help. The frozen state lasts for 5+ minutes. It's really frustrating and gets in the way of normal work, because it freezes Save As dialogues, ls commands, etc. If I issue a umount on the mount point, it either hangs also, or reports that the mount point is in use. Eventually, the dead state resolves itself, and the mount point gets unmounted, or it becomes possible to umount with no delay. My guess is that this happens when the connection/mount has gone idle, or when the Windows machine has been idle. I am not really sure. Why is this happening, and what can I do to prevent it? Or how can I successfully kill these D-state processes at will? Possibly related: CIFS mounts hang on read

• KVM Hosting: How to efficiently replicate guests

  - by javano

  I have three KVM servers each with 1 guest VM, running directly on it's local storage, (so they are essentially getting a dedicated box worth of computing power each). In the event of a host failure I would like the guests replicated to at least one of the other hosts so I can spin it up there, until the failing host is fixed. I am curious about KVM cloning. I can clone a VM live or when it's suspended/shutdown. Obivously suspended VMs will naturally be quicker to clone but these three VMs comprise three parts of a single solution, so I don't want to ever have any one of them shutdown. How can I efficiently clone these VMs between servers? I have had a couple of ideas, but are these insane or, is there a better method I have missed for my scenario? Set up a DRDB partition between box 1 and 2 where VM 1 runs from, and so is replicated between box1 and box 2, repeat between box 2 & 3, and box 3 & 1 (This could be insane, I have never used DRDB only read about it) Just use standard KVM CLI clone options to perform live clones (I'm dubious about this because I don't know how long it will take and what the performance impact will be during) Run a copy of each VM on at least one other host, and have the guest on one host export it's data to the matching guest on another host where it can import that data, scripting this on the guest) Some of other way? Ideas welcome! Side Note These servers have 4x15k SAS drives in a RAID 10 so they aren't rocketing fast, and as I mentioned, each VM runs from the host's local storage, no NAS or SAN etc. So that is why I am asking this question about guest replication. Also, this isn't about disaster recovery. Guests will be exporting their data to a NAS over a VPN, so I am looking at how I can have them quickly spun up in a host failure situation.
