  • GVIM hangs when saving through GVFS' FTP

    - by Lie Ryan
    I loved Gnome's Nautilus and FTP integration and being able to mount a remote FTP directory as a regular bookmark/directory, and double clicking any remote files to open in any unmodified program. I also loved editing text files with GVim. However, if I double clicked file on Nautilus to open a text file in Gvim, then saving a file will take about 10 seconds and GVim will hang for that amount of time. The major irritant is that I cannot continue editing while the text editor is waiting for the write to finish, this delay interrupted my workflow and thought process and saving becomes a painful process. The other problem is that I don't think simply uploading a file should take that much time. I'm aware of GVim's internal FTP support, but they are not as well integrated with Nautilus's FTP. So a few question: Is there a way to make GVim or GVFS to save in background while I continue editing? Why is GVFS so slow? Is there any way to set GVFS to use a single persistent FTP connection instead of creating a new FTP connection each time? I'm on Gentoo Linux x86-64.

  • Accidentally dd'ed an image to wrong drive / overwrote partition table + NTFS partition start

    - by Kento Locatelli
    I screwed up and set the wrong output for dd when trying to copy a freenas iso, overwriting the wrong external hard drive. Ironically, I was trying to setup a freenas server for data backup... External drive is only used for data storage, system is entirely intact Drive had a single NTFS partition filing the entire device (2TB WD elements) Drive originally had an MBR partition table. Drive now shows as having a GPT, presumably from the freenas image. Drive was mounted at the time, with maybe a couple kB of data written/read after running dd Drive is just a few months old and healthy (regular SMART / fs checks) I have not reboot the OS (crunchbang) /proc/partition still holds the correct information (and has been stored) Have dd's output (records in / out / bytes) testdrive did not find any partitions on quick or deep search running photorec to recover the more important data (a couple recent plaintext files that hadn't been backed up yet). Vast majority of disk content ( 80%) is unnecessary media files. My current plan is to let photorec do it's thing, then recreate the mbr with gparted and use cfdisk to create another NTFS partition using the sector information from /sys/block/.../. Is that a good course of action (that is, a chance of success)? Or anything else I should try first?

  • Why are my Windows 7 updates continuously failing?

    - by Chris C.
    I'm an advanced level user here with an odd issue. I have two Windows Updates that are failing to install, every single time. I'm getting a mysterious "Code 1" error on both updates, an error for which I'm having difficulty finding a solution. The updates in question are: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [May 2011] Because these updates are failing, the Shut Down button in my start menu always has the shield icon next to it, indicating that "new" updates will be installed on shut down. But, of course, they'll fail and when the PC is restarted, the shield icon is still there. When checking the update history and viewing the details of the failed updates, I get the following: Security Update for Microsoft Visual C++ 2008 Service Pack 1 Redistributable Package (KB2538243) Installation date: ?6/?29/?2011 3:00 AM Installation status: Failed Error details: Code 1 Update type: Important A security issue has been identified leading to MFC application vulnerability in DLL planting due to MFC not specifying the full path to system/localization DLLs.

  • Matching up HomeGroup users created in different versions of Windows

    - by pdr
    In our household, we have 2 laptops and a desktop, all currently on Windows 8.1. The desktop has been upgraded in stages from Windows 7. Laptop 1 was bought with Windows 8 and has now been upgraded. Laptop 2 is new and came with Windows 8.1. We've been trying to set up a HomeGroup such that we have one user on laptop 1, one on laptop 2 and both can log into the desktop, with each user able to edit their files on their laptop and desktop, while the other user has read-only access. And we now have that situation ... except ... because the user on laptop 1 was created in Windows 8 but the same user on the desktop was created in 8.1, they have different names in Windows Explorer (say, firstuser and first_000). Likewise, the other use was created on laptop 2 in Windows 8.1 and on the desktop in Windows 7 (so let's say secon_000 and seconduser). This is ultimately confusing. Now if we expand the HomeGroup, we get four users (firstuser, first_000, seconduser and secon_000) and each has a single computer inside it. What I'd like to see is firstuser = laptop1, desktop and seconduser = laptop2, desktop. An acceptable alternative is first_000 = laptop1, desktop and secon_000 = laptop2, desktop. But what I don't want to have to do is delete firstuser and seconduser and rebuild them. Is there a better way?

  • Hadoop streaming job on EC2 stays in "pending" state

    - by liamf
    Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

  • SQL Server Subscriber Migration

    - by SuperCoolMoss
    We're currently have one way transaction replication from a SQL Server 2005 OLTP publisher/distrbituor to two subscribers (one SQL 2005 and the other SQL2008 R2). Replication security is via the SQL Agents' domain service account (the same account is used on all boxes). The SQL2008R2 subscriber is used for BI purposes and hosts a database that has a subset of the Production publisher database tables, with different security and indexes. We need to migrate this BI subscriber to a newer box with more performant hardware. The plan is as follows: Stop replicating to the BI box (continue replicating to the other subscriber). Backup all databases on the BI box (including system databases). Restore all databases (including master in single user mode) to the new BI box (this has SQL Server 2008R2 already installed). Take the old BI box off the network and shut it down. Rename and Re-IP the new BI box to be the same as the old box. Switch replication back on. Are there any flaws in this approach?

  • xcopy Not Surpressing File/Directory Query

    - by Daniel Bingham
    Hey folks, I'm attempting to use xcopy to copy over a file from one machine to another on our network as part of a Java program. I'm calling xcopy like this: xcopy "C:\Program Files\path\to\my\file" "\\othermachine\c$\Documents and Settings\<myUserName>\Desktop\Test\path\in\directory\structure\to\file" /e /y /i Because I'm calling it from with in Java, I need all the prompts to be suppressed. For the most part, \i and \y have done exactly that. However, for this one file /i fails and I get the file or directory prompt. The result is that it hangs the entire program. I've also tried calling it with /s /t /q appended on to the existing options, to no avail. Why isn't /i working to suppress the File or Directory prompt? Is there an order I need to call the options in? Is there something else I need to do? EDIT: I should mention, the file is a text file - single line of text. It does not have an extension. It looks like this: FILE-NAME

  • SSH does not allow the use of a key with group readable permissions

    - by scjr
    I have a development git server that deploys to a live server when the live branch is pushed to. Every user has their own login and therefore the post-receive hook which does the live deployment is run under their own user. Because I don't want to have to maintain the users public keys as authorized keys on the remote live server I have made up a set of keys that 'belong's to the git system to add to remote live servers (In the post-receive hook I am using $GIT_SSH to set the private key with the -i option). My problem is that because of all the users might want to deploy to live, the git system's private key has to be at least group readable and SSH really doesn't like this. Here's a sample of the error: XXXX@XXXX /srv/git/identity % ssh -i id_rsa XXXXX@XXXXX @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Permissions 0640 for 'id_rsa' are too open. It is required that your private key files are NOT accessible by others. This private key will be ignored. bad permissions: ignore key: id_rsa I've looked around expecting to find something in the way of forcing ssh to just go through with the connection but I've found nothing but people blindly saying that you just shouldn't allow access to anything but a single user.

  • How to connect AD Explorer from Sysinternals to Global Catalog

    - by Oliver
    I'm using the sysinternals AD Explorer quite frequently to search and inspect an Active Directory without any big problems. But now i'd like to connect not only to a single AD Server. Instead i like to inspect the global catalog. If i enter within the AD Explorer connect dialog only the dns name of the machine (e.g. dns.to.domain.controller) that is serving the global catalog i only receive the concrete domain for which it is responsible, but not the whole forest (that's normal behaviour and expected by me). If i'm going to add the default port number (3268) for the global catalog in the form dns.to.domain.controller:3268 AD Explorer will simply crash without any further message. The global catalog itself works as expected under the given name and port number, cause our apache server use exactly this address and port number to authenticate some users. So any hints or tips to access the global catalog out of AD Explorer? Or there are any other nice tools like AD Explorer out there that doesn't have any problems to access the global catalog?

  • How to quickly check if two columns in Excel are equivalent in value?

    - by mindless.panda
    I am interested in taking two columns and getting a quick answer on whether they are equivalent in value or not. Let me show you what I mean: So its trivial to make another column (EQUAL) that does a simple compare for each pair of cells in the two columns. It's also trivial to use conditional formatting on one of the two, checking its value against the other. The problem is both of these methods require scanning the third column or the color of one of the columns. Often I am doing this for columns that are very, very long, and visual verification would take too long and neither do I trust my eyes. I could use a pivot table to summarize the EQUAL column and see if any FALSE entries occur. I could also enable filtering and click on the filter on EQUAL and see what entries are shown. Again, all of these methods are time consuming for what seems to be such a simple computational task. What I'm interested in finding out is if there is a single cell formula that answers the question. I attempted one above in the screenshot, but clearly it doesn't do what I expected, since A10 does not equal B10. Anyone know of one that works or some other method that accomplishes this?

  • Set up Linux box as WAP for MyBookLive?

    - by AcidFlask
    I inherited an old Linux box as well as a MyBookLive and would like to make the MyBookLive available over my wireless, essentially using the Linux box as a wireless access point. I just wiped the Linux box (home) and installed Ubuntu 12.04 on it. My network setup currently looks like this: (192.168.0.1 netmask 255.255.255.0) ISP --- wireless router --- wlan0 on home (192.168.0.12) | eth0 on home --- MyBookLive MacBook (192.168.0.11) so that the MyBookLive is basically a glorified external hard drive. The router does have an Ethernet port, but it is being used by my roommate's computer so I can't plug the MyBookLive directly into it. Right now I can ping MyBookLive.local and MacBook.local from home, but I am having trouble understanding and figuring out what the correct iptables commands are to make my MacBook see my MyBookLive through the Bonjour network. Also, I'm not sure if I need to set up DNS to forward xxx.local Bonjour/Zeroconf addresses. I tried the following to forward my entire wired network (which has only my MyBookLive) to a single IP address: sysctl net.ipv4.ip_forward=1 iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT iptables -t nat -A PREROUTING -i eth0 -p tcp -j DNAT --to 192.168.0.66 iptables -t nat -A PREROUTING -i eth0 -p udp -j DNAT --to 192.168.0.66 but I can't ping this address from my MacBook. This is probably horribly wrong, but I am a complete noob at setting up this kind of network and could use some expert help with setting this up properly.

  • Windows 7 access denied to executables.. by what?

    - by stijn
    Ever since I started using Windows 7 this problem has been bothering me. From time to time I see similar questions popping up on misc forums, but never did I see an answer. Here are two scenarios that nearly always reproduce it: the explorer way with explorer, navigate to a directory containing at least one exe file go one directory up immediately delete the directory just navigated to yields Folder Acces Denied dialog stating You need permission to perform this action You require permission from Administrators to make changes to this folder, with the buttons try Again and Cancel hitting Try Again never works immediately. Waiting a minute or so and then clickig it again does work note: if in step 2 and waiting a minute or more before going up one directory, the problem does not occur and the folder can be deleted the visual studio way build a project producing an exe file run the executable then close it immediately build the project again (by changing a single character in a source file for example) yields fatal error LNK1168: cannot open /path/to/the.exe for writing note: if in step 2 and waiting a minute or more before building again, the problem does not occur some specs happens both on Windows 7 32 and 64 bit, with VS2008/2010/2011 happens on 3 different machines I do not have a virusscanner of any kind I do have a bunch of services disabled, but nothing that prevents Windows from running normally, UAC is disabled as well happens on any type of disc I always use a user account that is in the Administrators group Obviously both scenarios are very similar and extremely reproducable. So I figured some process must have the file open for some reason, and release it again later. However, using systinternal's handle -a the exe file in question never shows up. (that is the correct way to use handle, right?) So while explorer/VS are reporting they cannot access the file, handle.exe says it's not in use anywhere. This leaves me rather clueless, so I'm wondering if someone can come up with a solution: why does this happen, and how to solve it?

  • Completely unintuitive Apache/PHP memory-freeing behavior

    - by David
    Okay, this one's weird. I have a Turnkey Linux server with a gig of dedicated RAM. It's running WP3.2 with a boatload of plug-ins. It's a new site, so it has very limited traffic (other than search engines, maybe 20 hits a week). Now, for a few weeks, every few days, it would max out on main RAM, start eating up virtual RAM, and then crash. It's had this behavior for a while and I've been trying to figure out which element was causing the crash. Nine days ago, I pointed my external server monitor to this server. I wrote a 5-line HTML file (not PHP and not WP) that the server monitor accesses every minute, to see if the server is up. So, now, nine days later, the server has been rock solid, up all the time, no memory leak at all. I changed NOTHING on the server itself to see this behavior change. Have you EVER seen anything like this? All the server monitor is doing is retrieving a single, super-simple HTML file and all the memory leak problems have gone away. Weird, eh?

  • Changing time intervals for vSphere performance monitoring, and is there a better way?

    - by user991710
    I have a set of experiments running on a cluster node which is running ESXi 5.1, and I want to monitor the resource consumption on the node itself. Specifically, I am currently running experiments on a subset of the VMs on the ESXi host and wish to monitor resource consumption on those specific VMs. Right now, since I'm using only a single ESXi host, I am using vSphere to access it and the performance reports. Ideally, I would like to get these reports for different time intervals. I can already get the charts for a time interval of 1h, but these are rather long-running experiments and something like 2h, 3h,... would be preferable. However, I cannot seem to change the time interval. Here is an example of what my Customize Performance Chart dialog shows: I am also running on a trial key at the moment. How can I change this interval? Do I need a standard license, or do I just need to turn off the VM (unlikely, but I haven't attempted it yet as these are long-running experiments)? Any help (or pointers to documentation which deals with the above -- I've already looked but did not find much) would be greatly appreciated.

  • Check for unique rows, but ignore one particular column

    - by user269148
    I have an XML document, that looks like this: Column A to S with headers, and there are 1922 rows. This is an backup of some SMS, and I want to get rid of duplicates. The problem is, that the Time in the readable_date header has been messed up. There is nothing wrong with the date, but the clock time is wrong, so I have split that column in three, with Year, day and clock. I know I can use a standard filter, but it only looks for unique rows in a single column. What I want to perform, is to make a row check similar to this: F(x)=Check if Column 2A to (infinate) is equal to Column 3A to (infinate), but ignore column(R). IF True, then delete Column 3A to (infinate) Otherwise Check IF column 2A to (infinate) is equal Column 4A to (infinate) and so on. I need to ignore a particular column in a row every time, and need to do this for a complete sheet. And the formula check should apply for every row, when the first one is done checking for duplicates... If anyone else has a better solution, please say so. Anyway, anyone who can help?

  • External Storage for 2TB of backups and 4TB of data RAID level? HW vs Software?

    - by Jerry Mayers
    I have a Mac Mini set up as a media center/file server. Currently I just have a hodgepodge mess of external drives for storage. I'm maxed out, and I have some new laptops on the way with much larger drives and I need to work out a good storage solution for backing them up, as well as storing media on the server. I need around 2 TB of storage for the time machine backups from my various systems and around 2 TB more for media. I would like to build this to handle around 6 TB total so I have some growing room. Since I'm using a Mac Mini as the server I need to use external enclosure(s) that support USB 2 or Firewire 800 (preferred) or gigabit Ethernet. Performance of the system isn't a huge concern since the majority of the access from other computers is done over 802.11N. I plan on using 2TB drives, for the final version, but initially I'll try and use my existing 2 (1TB) drives + some new 2TB drives, and swap the 1TB ones out as I fill up. As to the actual questions: Should I use hardware RAID in some enclosure? Because if the enclosure dies I have to find an identical one to get to my data right? Wouldn't a software RAID be better as I can use any method of connecting the drives to the system? Remember OS X server is my OS. What if I had to reinstall OS X, can I restore the software RAID easily? What RAID version should I use? For the 2TB used for the time machine disk I don't see why I need RAID here, just a single 2TB drive since its already the backup, but for the remaining 4TB it would be the only copy of the data so I should build some redundancy. I had a RAID 5 setup using a cheep RAID PCI card years ago running RAID 5 in a 2 TB array and when a drive died it wanted 48 hours to rebuild. Is this crazy slow for a setup of this size or is this to be expected? Any suggestions as to drive enclosures?

  • Reliable backup software for windows network/samba shares.

    - by Eli
    Hi All, I have a Win2003 server that works as a pdc for a number of XP boxes, and a couple related FreeBSD boxes. I need to back up roaming profiles, non-roaming profiles via network shares, local hard drive data, and files on the FreeBSD boxes via samba shares. I have tried Genie Backup Manager and Backup4All pro, and both have excellent features, but both also begin to fail disastrously with more than a few days use. Mostly, the errors seem to have been from the backup catalog getting out of synch with itself. Whatever it is, there is no excuse for a backup software that says it backed up files when it really didn't, or the log saying it backed up exactly the same file 10,000 times in a single run, or flat-out crashing, or any of the other myriad problems I've run into with these. Really sad for products that fill such an important need. Anyway, does anyone know of a backup software that works reliably and can do the following? Scheduled backups for multiple jobs, without a user logged in. Backup from local hard drives or network shares. Incremental backups. Thanks! Edit: Selected solution: I've added my (hopefully final) solution as an answer.

  • Hide/Replace Nginx Location Header?

    - by Steven Ou
    I am trying to pass a PCI compliance test, and I'm getting a single "high risk vulnerability". The problem is described as: Information on the machine which a web server is located is sometimes included in the header of a web page. Under certain circumstances that information may include local information from behind a firewall or proxy server such as the local IP address. It looks like Nginx is responding with: Service: https Received: HTTP/1.1 302 Found Cache-Control: no-cache Content-Type: text/html; charset=utf-8 Location: http://ip-10-194-73-254/ Server: nginx/1.0.4 + Phusion Passenger 3.0.7 (mod_rails/mod_rack) Status: 302 X-Powered-By: Phusion Passenger (mod_rails/mod_rack) 3.0.7 X-Runtime: 0 Content-Length: 90 Connection: Close <html><body>You are being <a href="http://ip-10-194-73-254/">redirect ed</a>.</body></html> I'm no expert, so please correct me if I'm wrong: but from what I gathered, I think the problem is that the Location header is returning http://ip-10-194-73-254/, which is a private address, when it should be returning our domain name (which is ravn.com). So, I'm guessing I need to either hide or replace the Location header somehow? I'm a programmer and not a server admin so I have no idea what to do... Any help would be greatly appreciated! Also, might I add that we're running more than 1 server, so the configuration would need to be transferable to any server with any private address.

  • Configuring two nearby WLANs: should I use the same ssid?

    - by Rory
    I'm configuring a home network for basic internet use (ie don't really need connectivity between workstations on the network). My brick walls mean a single wireless router doesn't provide good coverage throughout the house, so I have purchased two powerline adapters and now have the incoming modem/wireless router at one end of the house plugged into a powerline adapter, and at the other end of the house the other powerline adapter plugged into another wireless router. Currently the two wireless networks have different ssids. (The powerline adapters only do power-Ethernet; they're not wireless access points themselves.) This works well, except when I move between rooms and would ideally like my devices (iPad, phones, laptops) to switch from the weak to the strong signal. Sometimes there's enough signal that they hold on to the weak connects instead of switching to the strong one. Should I name the two networks the same ssid, and if so what is the actual effect? Do the signals get confused, is the bandwidth affected, will this help my devices seamlessly move from one to the other, or is the ssid just a cosmetic thing that actually doesn't have any impact on this situation? Are there any other settings that I should configure to make my setup optimal?

  • Apache Virtual Hosts behind Cisco Router

    - by Theo
    I'm setting up an Apache 2.2 Ubuntu web server for internal services that is also supposed to be accessed from outside our LAN. Our LAN has a single external IP that is the external IP of our RV042 Cisco router. We have set up several A records on our external DNS server that point to this IP. Our internal DNS server resolve the same records to the internal IP of our web server, so computers from inside the network can access them using the same address as if they were outside. We forwarded the router's external 80 port to our web server's 80 port. I have set up one Virtual Host for each domain name in our list, and my httpd.conf is something like this: ServerName web.domain.com NameVirtualHost *:80 <VirtualHost *:80> ServerName alfresco.domain.com <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /alfresco http://localhost:8080/alfresco ProxyPassReverse /alfresco http://localhost:8080/alfresco ProxyPass /share http://localhost:8080/share ProxyPassReverse /share http://localhost:8080/share </VirtualHost> <VirtualHost *:80> ServerName crm.domain.com DocumentRoot /var/www/sugarcrm </VirtualHost> Now, this works if we are in our LAN. However, if we are outside of our LAN we reach our web server's default page saying: It Works! This is the default web page for this server. But we can't reach the virtual hosts, as if the domain name is not being preserved when the router forward the packets to the web server. Am I doing something wrong? How can I check what is going on? What should be the settings to make this work from outside?

    - by Jeff King
    i'M GOING MAD! UNtil last friday I had been successfully using wifi with the supplier as VIRGIN through their Motorola SB 4200 cable Modem and the wireless router being the Linksys WRT 54G router. Supported were three lap tops and an EPSON 510W printer and this had been running with no issue for about 3 years. Back to last friday, we started suffering significant delays and then the network collapsed with no wireless access. I was able to connect a single laptop direct to the cable modem and internet access was restored to just that one device. I thought that the problem was the router so I tried a backup D-Link device with no success. I have subsequently bought another cable modem AND a netgear router plus addidtional ethernet cables but with no success. The best that happens is that the signal appears good but I cannot get access to the internet. A yellow question mark appears on the 'gradient' icon. Each laptop and router works elsewhere so I'm stumped. Mind you I am a real novice so I'm not surprised. Please can anyone tell me what I'm doing wrong?

  • nVidia performance with newer X and newer driver abysmal with Compiz

    - by Nakedible
    I recently upgraded Debian to Xorg 2.9.4 and installed nvidia-glx from experimental, version 260.19.21. This was somewhat of an uphill battle as the dependencies for the experimental nvidia-glx package are still somewhat broken. I got it to work without forcing the installation of any packages and without modifying the packages. However, after the upgrade compiz performance has been abysmal. I am using the desktop wall plugin and switching viewports is really slow - takes a few seconds for each switch. In addition to this, every effect that compiz does, such as zoom animations for icons when launching applications, takes seconds. The viewport switching speed changes relative to the amount of windows on that virtual screen - empty screens switch almost at normal speed, single browser windows work almost decently, but just 4 rxvt terminals slows the switches down to a crawl. My compiz configuration should be pretty basic. Xorg is likewise configured without anything special - the only "custom" configuration is forcing the driver name to be "nvidia". I've fiddled around with the nvidia-settings and compizconfig trying different VSync settings, but none of those helped. My graphics card is: NVIDIA GPU NVS 3100M (GT218) at PCI:1:0:0 (GPU-0). This is laptop GPU that is from the Geforce GTX 200 series. Graphics card performance should naturally be no problem. EDIT: In the end, nothing really worked, and I got really annoyed with the state of compiz and its support in Debian. Many nVidia driver revisions have passed and I am using Gnome 3 now, so I am accepting the best answers to this question even though the issue was not resolved.

  • Simple, centralized user management on a small LAN - NIS or LDAP?

    - by einpoklum
    I'm setting up a small LAN for my team. It will, for all intents and purposes, not be connected to any external networks. I would it to have centralized control of user accounts (at least, I think I'd like that; I'm also considering using puppet, so theoretically I could just push /etc/passwd changes, or something). The number of machines is fixed, but not very small. Mostly they're 'attached' to a single user, but sometimes people work remotely on someone else's box; and there are a couple of servers. I've read this question, but my scenario is much simpler (even simpler than in this question) and I'd like to do something (relatively) quick, with not much hassle, but not a dirty totally-insecure hack. Is NIS relevant for my scenario? If not, what's the most hassle-free way to set up LDAP (or LDAP+Kerberos) to achieve the same? Notes: I have no experience with setting up either NIS or LDAP. We use Debian-flavored Linux distributions, mainly Kubuntu 12.04 (not my choice, but that's the way it is).

  • Distributed storage and computing

    - by Tim van Elteren
    Dear Serverfault community, After researching a number of distributed file systems for deployment in a production environment with the main purpose of performing both batch and real-time distributed computing I've identified the following list as potential candidates, mainly on maturity, license and support: Ceph Lustre GlusterFS HDFS FhGFS MooseFS XtreemFS The key properties that our system should exhibit: an open source, liberally licensed, yet production ready, e.g. a mature, reliable, community and commercially supported solution; ability to run on commodity hardware, preferably be designed for it; provide high availability of the data with the most focus on reads; high scalability, so operation over multiple data centres, possibly on a global scale; removal of single points of failure with the use of replication and distribution of (meta-)data, e.g. provide fault-tolerance. The sensitivity points that were identified, and resulted in the following questions, are: transparency to the processing layer / application with respect to data locality, e.g. know where data is physically located on a server level, mainly for resource allocation and fast processing, high performance, how can this be accomplished? Do you from experience know what solutions provide this transparency and to what extent? posix compliance, or conformance, is mentioned on the wiki pages of most of the above listed solutions. The question here mainly is, how relevant is support for the posix standard? Hadoop for example isn't posix compliant by design, what are the pro's and con's? what about the difference between synchronous and asynchronous opeartion of a distributed file system. Though a synchronous distributed file system has the preference because of reliability it also imposes certain limitations with respect to scalability. What would be, from your expertise, the way to go on this? I'm looking forward to your replies. Thanks in advance! :) With kind regards, Tim van Elteren
