• Connect to WEP Wireless Network by command line on Ubuntu

  - by Tim

  Hi, I am a newbie to both network and Linux. I am now trying to connect to a WEP wireless network by command line on my Ubuntu 8.10, because the Network Manager does not support 64 bit WEP. (1) I firstly bring down the Network Manager and then try to connect to a wireless network, whose essid is candy and password is 5673212741. But it fails as shown in the following. I wonder why and how to do it correctly? $ sudo /etc/init.d/NetworkManager stop * Stopping network connection manager NetworkManager [ OK ] $ sudo iwconfig wlan0 essid candy opendo iwconfig wlan0 key 18018ce78e open $ sudo iwconfig wlan0 key 5673212741 open $ sudo dhclient wlan0 There is already a pid file /var/run/dhclient.pid with pid 9971 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.1 Copyright 2004-2008 Internet Systems Consortium.

• Connect to Nonencrypted Wireless Network Using Ubuntu Commands

  I failed to connect to an open i.e. nonencrypted wireless network using Ubuntu command lines.

• Understanding RedHats recommended tuned profiles

  - by espenfjo

  We are going to roll out tuned (and numad) on ~1000 servers, the majority of them being VMware servers either on NetApp or 3Par storage. According to RedHats documentation we should choose the virtual-guestprofile. What it is doing can be seen here: tuned.conf We are changing the IO scheduler to NOOP as both VMware and the NetApp/3Par should do sufficient scheduling for us. However, after investigating a bit I am not sure why they are increasing vm.dirty_ratio and kernel.sched_min_granularity_ns. As far as I have understood increasing increasing vm.dirty_ratio to 40% will mean that for a server with 20GB ram, 8GB can be dirty at any given time unless vm.dirty_writeback_centisecsis hit first. And while flushing these 8GB all IO for the application will be blocked until the dirty pages are freed. Increasing the dirty_ratio would probably mean higher write performance at peaks as we now have a larger cache, but then again when the cache fills IO will be blocked for a considerably longer time (Several seconds). The other is why they are increasing the sched_min_granularity_ns. If I understand it correctly increasing this value will decrease the number of time slices per epoch(sched_latency_ns) meaning that running tasks will get more time to finish their work. I can understand this being a very good thing for applications with very few threads, but for eg. apache or other processes with a lot of threads would this not be counter-productive?

• How to test nginx proxy timeouts

  - by mkorszun

  Target: I would like to test all Nginx proxy timeout parameters in very simple scenario. My first approach was to create really simple HTTP server and put some timeouts: Between listen and accept to test proxy_connect_timeout Between accept and read to test proxy_send_timeout Between read and send to test proxy_read_timeout Test: 1) Server code (python): import socket import os import time import threading def http_resp(conn): conn.send("HTTP/1.1 200 OK\r\n") conn.send("Content-Length: 0\r\n") conn.send("Content-Type: text/xml\r\n\r\n\r\n") def do(conn, addr): print 'Connected by', addr print 'Sleeping before reading data...' time.sleep(0) # Set to test proxy_send_timeout data = conn.recv(1024) print 'Sleeping before sending data...' time.sleep(0) # Set to test proxy_read_timeout http_resp(conn) print 'End of data stream, closing connection' conn.close() def main(): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind(('', int(os.environ['PORT']))) s.listen(1) print 'Sleeping before accept...' time.sleep(130) # Set to test proxy_connect_timeout while 1: conn, addr = s.accept() t = threading.Thread(target=do, args=(conn, addr)) t.start() if __name__ == "__main__": main() 2) Nginx configuration: I have extended Nginx default configuration by setting explicitly proxy_connect_timeout and adding proxy_pass pointing to my local HTTP server: location / { proxy_pass http://localhost:8888; proxy_connect_timeout 200; } 3) Observation: proxy_connect_timeout - Even though setting it to 200s and sleeping only 130s between listen and accept Nginx returns 504 after ~60s which might be because of the default proxy_read_timeout value. I do not understand how proxy_read_timeout could affect connection at so early stage (before accept). I would expect 200 here. Please explain! proxy_send_timeout - I am not sure if my approach to test proxy_send_timeout is correct - i think i still do not understand this parameter correctly. After all, delay between accept and read does not force proxy_send_timeout. proxy_read_timeout - it seems to be pretty straightforward. Setting delay between read and write does the job. So I guess my assumptions are wrong and probably I do not understand proxy_connect and proxy_send timeouts properly. Can some explain them to me using above test if possible (or modifying if required).

• Failed to re-publish a page - Tridion 2011 SP1

  - by Wilson Yu

  We are getting some strange error when re-publishing the same page. The page was published successfully the first time and we can see the page from presentation server. It failed with the following error (see below) when we tried to publish it again (no change to page). The page ran OK within template builder and we got the correct html output, it failed in the last committing deployment step (Prepare Transport, Transporting, Preparing Deployment and Deploying are all successful). Once it fails to publish the second time, it always fails to publish, and we can't un-publish it either. Also when we make a copy of the failed page and create a new page, we can publish the new page first time, the new page then fails to publush the second time with the same error. Does anyone know what would cause this error? any help would be greatly appreciated. Here is the error msg: Committing Deployment Failed Phase: Deployment Prepare Commit Phase failed, Unable to prepare transaction: tcm:0-4210-66560, For input string: "", For input string: "", Unable to prepare transaction: tcm:0-4210-66560, For input string: "", For input string: ""

• I'm looking for a program that can automate opening/closing a program

  - by Peterstone

  I am looking a for a program to remember things with these features: Open files or programs in my own computer at a planned time. For example I want every morming at 8:00 the program open a particular mp3 file. But suposse, by mistake, that I on my computer and 9:00, then I want that the program rememberme what I planned to open at 8:00. Show me the program as an active windows on my desktop. The windows of the program opened is what the user is seeing (Is at the first place in the desktop) and the rest of the program windows are below. Close programs or files in my own computer at a planned time. For example I want that the program mp3 file that was opened at 8:00 was closed at 10:00 if at that time still be opened. Detection of events. For instance If I open particular videogame program. then a mp3 file (with a recording message arguing why I shouldn´t continue playing that videogame at work time) is opened. Possibility of combine the features mentioned before each other.

• HP Photosmart C4780 printer/scanner breaks netgear WNDR3700v3 router on connection

  - by CodeJunkie

  A few months ago, we upgraded our Netgear router's firmware. Immediately, we started having trouble connecting to the internet. Each time this problem would happen, every device in the house would stop being able to make new connections to the internet. For example, you couldn't open new pages in the browser, but if Skype was running when the problem happened, you could keep talking to people. The only solution to this problem seemed to be resetting the router to factory defaults. Eventually, we solved this problem by just downgrading the router firmware. A while later, we got a new Netgear router. Almost right away, the new router started having exactly the same problems as the old one did on current firmware. The network connection would stay active and the computer would say it had an internet connection, but you couldn't do anything online except for using Skype. We eventually figured out that this happens every time our HP printer gets onto the network. Any time the printer gets onto the wireless network, the whole network stops connecting to the internet almost completely. The only thing that will fix it at that point is to reset the router to factory specs, and unplug the printer so it can't get back onto the network. The Netgear router has the latest version of the firmware, but the printer/scanner is very old. It looks to me like this problem is probably a result of a firmware conflict between the printer and the router, but I'm not sure how to fix that problem. Here's some additional information: Printer: HP Photosmart C4780 Router: WNDR3700v3 Router firmware: V1.0.0.22_1.0.17 (Stock, up to date firmware) Why would the printer getting on the network cause the router to not be able to access the internet correctly until it was reset? What can be done to allow the printer to be on the network without breaking the network for all other devices? Edit: One other thing that happens during this internet problem is that multiple computers in the house display an "IP conflict" message repeatedly, and extremely frequently (as often as every five to ten minutes, and every time a connection to the wireless is made).

• Sudden and frequent hangs on desktop computer: mobo or CPU fault?

  - by djechelon

  I have a desktop computer equipped with an ASUS Crosshair 2 Formula and a Phenom x6 3.2GHz CPU. My problem is that often the computer will hang all of a sudden, completely stopping responding. When that occurs, reset key is inoperative and power button turns the computer off but is unable to turn it back on. I have to physically disconnect power cable. The problem can occur anytime, when I'm booting Windows, when I'm logging in, when I'm listening to a song, when I'm browsing Internet, etc. It always occurs after very few minutes of 3D gameplay I thought it was a video card fault. I had 3 8800GTX so I could try all combinations of them: didn't fix I thought it was a RAM problem: I tried running with only a subset of my DDR2 banks but didn't fix. Almost every time I have to reset and reconfigure BIOS (without AHCI, Win7 won't boot, so I need to restore a few things). If I enable AMD Live, Cool&Quiet or other things from CPU configuration menu I'll be sure that the computer won't reach Windows desktop in 99% of cases (it randomly hangs somewhere in the boot process or even in the BIOS POST). Another interesting thing is that during the POST process the computer always takes unusually long time detecting USB devices (LCD POSTer shows USB INIT), and I've also tried disconnecting all USB devices but didn't take less time to POST BIOS revision is 2702, the latest. Today I found a different behaviour once: during boot screen I got a BSOD with error Stop 0x00000101 A clock interrupt was not received on a secondary processor within the allocated time interval, and this is usually related to overclocking, but I never overclocked my CPU. Judging from the description of my problem, hoping someone had the same and fixed, and since I don't have a spare CPU or motherboard for replacement, I'd like to ask if you think this is a problem with faulty CPU or faulty motherboard, and if I can perform additional tests (I mean software tests because of my lack of spare components) to identify the component to replace.

• Mavericks permission issues with Windows Server deduplicated shares

  - by dmohlmaster

  We have a number of 10.9-10.9.3 - Mavericks - machines installed throughout our facility. Much of the user content is pulled from shares stored on our Windows Server 2012 fileservers with deduplication enabled. I have found that files newly written or unoptimized are able to be accessed without issue - read, written, modified, etc. Once the file gets optomized/deduplicated and Windows adds the P & L attributes - sparse and symlink - the Macs running Mavericks begin to have access issues. Once the files get deduplicated, users begin receiving read access errors when copying files (see error1 below). This happens when copying to folders within the current folder tree or copying somewhere to the local system. If you 'stop' the copy operation and retry a few more times, it may eventually work for the specific instance but fail again later. I am however, able to copy these files without issue via the terminal. Other systems running 10.7 do not experience the same issues and are able to access file server resources without issue. Many of the systems having issues are newer and thus not able to be downgraded to 10.8 or 10.7. I have tried finder replacements such as Pathfinder but the results are the same. I know this is at least similar to the issues many Mac users are already experiencing and posting about but I haven't seen it directly linked to deduplication and the attributes written by Windows server. Has anyone seen this issue? Have any solutions been found? Error 1: When copying files after the PL attributes have been set by deduplication. "One or more items can't be copied to "Foler" because you don't have permissions to read them. ******************************************' Via the system.log, I am also seeing the following error when accessing these deduplicated file shares. The reparse point tag listed below is "IO_REPARSE_TAG_DEDUP" Reported error: "smbfs_nget: filename.ext - unknown reparse point tag 0x80000013"

• Method to integrate Powershell scripts with non-Windows workflow?

  - by Matt Simmons

  I love the smell of new machines in the morning. I'm automating a machine creation workflow that involves several separate systems across my infrastructure, some of which involve 15 year old perl scripts on Solaris hosts, PXE Booting Linux systems, and Powershell on Windows Server 2008. I can script each of the individual parts, and integrating the Linux and Unix automation is fairly straightforward, but I'm at a loss as to how to reliably tie together the Powershell scripts to the rest of the processes. I would prefer if the process began on a Linux host, since I imagine that it will end up as a web application living on an Apache server, but if it needs to begin on Windows, I am hesitantly okay with that. I would ideally like something along the lines of psexec for Linux to run against Windows, but the answer in that direction appears to by Cygwin, and as much as I appreciate all of the hard work that they put in, it has never felt right, if you know what I mean. It's great for a desktop and gives a lot of functionality, but I feel like Windows servers should be treated like Windows servers and not bastardized Unix machines (which, incidentally, is my argument against OSX servers, too, and they're actually Unix). Anyway, I don't want to go with Cygwin unless that's the last and only option. So I guess what I'm asking is if there is a way to execute jobs on Windows machines from Linux. Without Cygwin. I'm open to ideas and suggestions, including "Look idiot, everyone uses Cygwin, so suck it up and deal with it". Thanks in advance!

• I deployed Flash Player via a Software Installation policy. How to upgrade?

  - by eleven81

  I have a Windows Server 2008 machine as my DC. Earlier this year I created a Software Installation GPO to deploy Adobe Flash Player plugin MSI. I assigned the policy to the computers, about half run Windows XP x86 and the other half Windows 7 x64. That all works like clockwork. When I created the Software Installation Policy, I disabled the Flash Player plugin's automatic update feature by editing the MSI in Orca. I did this because I wanted all of my machines to run the exact same version of the plugin. Now, some time has passed and a newer version of the Flash Player plugin has been released. It is time for me to push out the updated version of the plugin. I already have the new MSI, but I am lost on what to do next. I see the upgrades tab in the Software Installation GPO, but everything there reads like that would be used for add-ons to a larger master program and not for updates that are released over time. I have read that it is best to create a new Software Installation policy with the new MSI, revoke the old GPO, and assign the new GPO. I feel as though, over time, I will wind up with more revoked policies than active ones. I have also read that some people have had success by replacing the old MSI with the new MSI and simply telling the GPO to redeploy. This seems like a backdoor method that will only get me in to trouble. In short, what is the correct, best-practice, or preferred way to roll out the new version via Group Policy?

• Server 2008 R2 domain windows update strategy

  - by Joost Verdaasdonk

  Let me explain my question a bit. We are a small company that have now made the first move to a bigger network. For now the network contains of 5 servers 2008 R2 (dc,sql,web,etc..). Everything we need is now in place but for now we cannot afford to finish the network by implementing redundant systems. (secondary dc, dns, sql cluster, etc...) For some people this is hard to understand but this is the current situation. (and we are aware and will fix this when we can) Because we want to keep our system secure and up to date I've made sure that all systems are updated regularly. The problem is ofc that the nr of updates Microsoft rolls out that need a system reboot seam to occur more often. (maybe I'm wrong and it just feels like this) ;-) In our domain servers depend on each other for services (like SQL, WEB, or whatever) so just rebooting a server at will is NOT a good idea! For now I update all of them without rebooting at once. After all are up to date I bring them down in the order they are depended on each other. After this I reboot all of them in the inverse order. I understand ofc that if I DID have redundancy in my system that updating and rebooting would not be such a problem because the server task could be taken over by another node but this is something we generally need to add when we can. So my question is. If you read my above situation can you suggest me more Update strategies or general ideas that could help me do this process in a better / faster way? Thanks for your thoughts!

• Master File Table Corrupt, any way to save data?

  - by domen

  hi. I've used search, but none of the results match my problem so I didn't have to ask separate question. I've Installed Windows 7 RTM recently and since then partitions located on one of my HDDs have gone "crazy". They used to "freeze" and didn't open in explorer for some time (minute or two, usually), sometimes all partitions of the drive wouldn't show until reboot and finally, one of those partitions started showing "disk structure is corrupted and unreadable" warning, it appeared in Disk Management window as RAW and chkdsk showed "mft corrupt". There were no important data on the partition and I didn't have enough time to analyze the problem at the moment, so I just reformatted it and ran antivirus scan on system. After that problem settled for some time, but yesterday the problematic HDD vanished again from the system. After reboot chkdsk identified mft of four partitions corrupt and now they are all in same conditions as the above mentioned one. But the difference is that the files stored in them are extremely important. and just for info: I upgraded from Win7 build 7077, but had some performance issues, so I reformatted system drive and installed fresh Win7 RTM on it. I've downloaded TestDisk and it shows all the partitions marked as NTFS (not RAW) and my knowledge of the program wasn't sufficient to obtain any other info from it :-) and the images that could help describe the problem (sorry, I'm not allowed to post images and more than one hyperlink): http:// img22.imageshack.us/img22/5909/chkdskz.jpg http:// img198.imageshack.us/img198/5576/computeray.jpg I'm interested, is there a way to let me restore the MFT or just access files so I can backup them before reformatting the drive. Thanks for your time. :) P.S. my reformatted drive is showing no problems, could there be a problem with windows 7 itself? I googled, but with no results.

• What are the replacement options for an IDE hard disk for a DOS based system?

  - by dummzeuch

  I have got a few "embedded" systems running MSDOS 6.2 which boot from and store data to IDE hard disks. Since these drives are nearing their end of life, the question arises how we can replace them. The requirements are: DOS must be able to install and boot from these drives. They must be able to sustain heavy (mostly) write access. If possible, they should be able to survive moderate vibrations (not too bad since the current hard disks have survived several years of that) I considered the following options so far: other ide hard drives: Unfortunately modern IDE drives are too large so DOS cannot boot from them even if I create small partitions. Older IDE drives are just that: old, so they are probably not the most reliable ones any more. SSDs: There are a few SSDs with IDE interface available. I have not yet tried them. Does anybody have any experience with them? They look like the ideal replacement provided that DOS can boot from them and that writing speed does not deteriorate too much (the old hard disks are no race cars either). Compact Flash: There are adapters for using CF with IDE controllers and they work fine. DOS can boot from them and they have no problems at all with vibrations. What I am not sure about is their durability. DOS uses FAT so some very few sectors are written every time the medium is being written to. IDE to SATA converters: I have no idea whether they are any good. Has anybody tried them? It might be an option to use one of these to connect an SATA SSD to the system. Are there any alternatives that I have missed? (We are working on replacing these systems, but it will still take a few years.)

• How can I change the binding order of network adapters in Windows 7?

  - by Chris Farmer

  The end goal here is that I am trying to install an Oracle 10g server on my Windows 7 x64 dev box. I use DHCP, and the Oracle installer is throwing up this warning: Checking Network Configuration requirements ... Check complete. The overall result of this check is: Failed <<<< Problem: The install has detected that the primary IP address of the system is DHCP-assigned. Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP. I have installed the loopback adapter, but I am not sure how to make it the primary network adapter. I see this Microsoft KB article on the subject but it's Windows XP-oriented, and I can't seem to find a comparable one for Windows 7. Some of the options it talks about don't seem to be present in the views of the adapters that I see. So, how can I make the loopback adapter become the primary adapter?

• Things to check for an internet-facing email server.

  - by Shtééf

  I'm faced with the task of setting up a public-internet-facing email server, that will be relaying mail for all of our other servers in the network. While the software in itself is set up in few keystrokes, what little experience I have with managing an email server has thought me that there are tons of awkward filtering techniques employed by other email systems. Systems that my own server will inevitably interact with a some point. Hence, my questions: What things should be kept in mind and double checked when setting up an email server? What resources are available for checking if my email server is set-up correctly? I'm specifically NOT looking for instructions for any given mail server, such as Exchange or Postfix. But it's okay to say: “you should have X and Y in your set-up, because when talking to server software Z, it typically tries to weed out open relays by checking for these.” Some things I've discovered myself: Make sure forward and reverse DNS are set up. Mail servers tend to do a reverse lookup for the peer IP-address when receiving. Matching a reverse look up with a follow-up forward lookup is probably employed to weed out open relays run through malware on home networks. Make sure the user in the From-address exists. The From-address is easily spoofed. A receiving mail server may try to contact the mail server in the From-domain, and see if the From-user actually exists.

• Apache https is slsow

• Weird problem with Visual C++ 2010 Express

  - by Robert Vella

  This has happened before on my Vista Premium installation, and now it's happening on my Windows 7 Home Premium installation. Basically everytime I install Visual Studio Express 2010, it works fine for a random amount of time but then suddenly starts to hide from my sight -- that's the best way I can explain it. VS does not crash, and from what I can tell it does not freeze either; It continues to work, I can even "minimize" and "maximize" it; I simply cannot see it nor can I interact with it any meaningful way. Also: After the "crash" there are no logs in: Root\Program Files (x86)\Microsoft Visual Studio 10.0\Microsoft Visual C++ 2010 Express - ENU. Nor any other files created at the time of the crash. There are no traces in the event viewer. The program seems to be functioning perfectly in the process manager. If I reinstall Visual C++, it works normally for a seemingly random period of time before going cookoo again. I am stumped. This has never happened to me before, with any other program. And yet I doubt it really is a problem with Visual C++; More like something general that seems to have picked on it for some reason. Still, after a clean install with a new OS, I'm kinda thinking there's something wrong here. Any help would be appreciated, altough I suspect that the answer to this question will make me feel embarassed. P.S. Not sure if it helps, but I think around the same time I started having problems (On both installations) with windows turning off the display when I leave the computer, and then seemingly crashing when it turns it on again -- in fact when I interact with it it seems to be responding to my commands without actually display anything.

• Changing the default boot option without losing the boot menu

  - by hvd

  I've had a working multi-boot setup with the Windows boot loader, containing menu items for two Windows 7 systems, and one for Grub. Grub in turn contains multiple menu items, but I think that's not relevant here. I've upgraded one system to Windows 8. When I now set a different system as the default, I lose the boot menu, and I lose the possibility of booting into the other systems. I've set Windows 7 as the default, rebooted, and get Windows 7, but I don't get to choose which system to boot into. I can run its own bcdedit to change the default back to Windows 8, and another reboot shows the boot menu again, but how can I avoid defaulting to Windows 8? Here are my current boot settings, is there anything that is misconfigured? C:\WINDOWS\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=F: description Windows Boot Manager locale nl-NL inherit {globalsettings} integrityservices Enable default {current} resumeobject {2f8b77f0-a30b-11e1-a9c6-a4bd8d37f662} displayorder {current} {2f8b77e3-a30b-11e1-a9c6-a4bd8d37f662} {2f8b77ee-a30b-11e1-a9c6-a4bd8d37f662} toolsdisplayorder {memdiag} timeout 30 Windows Boot Loader ------------------- identifier {current} device partition=C: path \WINDOWS\system32\winload.exe description Windows 8 locale nl-NL inherit {bootloadersettings} integrityservices Enable recoveryenabled No allowedinmemorysettings 0x15000075 osdevice partition=C: systemroot \WINDOWS resumeobject {2f8b77f0-a30b-11e1-a9c6-a4bd8d37f662} nx OptIn bootmenupolicy Standard Windows Boot Loader ------------------- identifier {2f8b77e3-a30b-11e1-a9c6-a4bd8d37f662} device partition=D: path \Windows\system32\winload.exe description Windows 7 locale nl-NL osdevice partition=D: systemroot \Windows resumeobject {59616f59-a2ba-11e1-b73a-806e6f6e6963} nx OptIn pae Default bootmenupolicy Standard hypervisorlaunchtype Auto detecthal Yes sos No debug No Real-mode Boot Sector --------------------- identifier {2f8b77ee-a30b-11e1-a9c6-a4bd8d37f662} device partition=C: path \grub\winloader\grub.boot description Grub 2

• Not able to access Silverlight.net and ONLY Silverlight.net - All other domains work!

  - by Sootah

  Alrighty folks, I have an extremely odd problem. I am able to surf the web fine with one odd (and really annoying at the moment) exception: Microsoft's Silverlight.net. Every other site that I go to works just fine. This is quite frustrating because I'm in the middle of programming a web app in Silverlight 4.0, and whenever I do a search for any code examples, tutorials, or whatnot at least 50% of the results are hosted in the silverlight.net forums. The error message that I get is: Oops! Google Chrome could not find www.silverlight.net It doesn't work in my other browsers either (both IE and FireFox). What's odd, is that while the error message would lead me to assume it's a DNS error, I can ping the URL just fine.

• DNS resolve .com domain on local domain

  - by Joost Verdaasdonk

  I'm building a local 2008 R2 domain as a test case to be able to write a roadmap for the real new domain that needs to be created soon. What I would like to know if I'm able to make a record in DNS that will point the domain name: www.example.com and example.com to one of the servers in my network. I tried creating an a-record for it but that doesn't work. To be honest I'm not even sure if this is possible? So can I do this? That way I would be able to fully test all our services (and webb app) offline before I build the real domain and switch the DNS records at the provider. Some advice if possible and where to start is appreciated. The solution (Thanks Brent): Create new Forward lookup zone pointing to example.com Create empty A record pointing to IP of the webserver you are targeting If www is needed create A record with Name: www and IP of your webserver sub domains repeat the process but then with names for example: sub or www.sub (and ip your webserver) Be aware of the DNS Cache while you are in this process. Things can take time or do the following: Right click the server and choose clear cache in CMD: ipconfig /flushdns (to flush the client cache)

• Managing rolling deployments in the cloud

  - by Josh Nankin

  Recently I've been experimenting with various cloud management tools like RightScale, Scalr, custom scripts for managing a variety of servers, each hosting several roles (app, db, load balancer, job queues, etc). The one thing I find lacking in most solutions is a way to do rolling deployments, i.e. running deployments sequentially across a number of servers with the same role. For instance, I dont want to build all of my webservers at the same time, as that will almost definitely result in some down time or 500s for my customers. I'd rather have one or two servers build at a time, while other servers are still available to handle requests. The other alternative is obviously to launch new servers that automatically update themselves on boot, but this isn't as cost effective, and most likely requires more time for the build to complete (it's faster to build on an existing server than to launch a new server and kill old ones). We've all heard of the big companies having the famous "push to build" button (companies like Twilio, Etsy, etc.) but it seems that they all have custom implementations of this. I'm not talking about a simple ssh-loop, clusterssh, or even an mcollective - I preferably want something with a nice simple interface that allows me to specify something like a RightScript or a Scalr script to run on a set of servers with a specific role, and it builds them sequentially. Does any one know of easy ways to get this done, or is this a candidate for a new open source project?

• Mesh Networked servers via vpn

  - by microspino

  I got a design idea and I would like to have some advice from SF about It. I have 5 customers with small real-estate databases. I've built for them a desktop app and now they would like to merge their database to share their data. I don't want to centralize everything in one place nor I want to do maintenance for servers. They told me also, that all of them in their offices, have little servers and maintenance guys available. Although everything seems suitable for web application, I had the idea to experiment something new: Any customer small-server wild be connected to the others in a sort of mesh network without a single point of failure and through VPNs. If one of the servers went down the customers could still connect to their databases from one of the other mesh networked servers instead of from the local one that is down. During normal operations all the servers sync the db with the others through VPNs. I can accept a half-day timing window of NON synched data, in other words, since I don't need real time synchronization, the server don't have to always stay in synch. I can migrate my data over to other Non-Sql technologies like CouchDB or Redis or whatever you suggest. As you can see I don't have a lot of constraints and although I could go with a web application I would like to delegate and decentralize support, data-privacy and management, as more as I can to my customers offices. Is that a crazy idea? Do you know If something similar exist? Which technology would you suggest?

• My bios datetime is resetting to 2002, what should I do?

  - by Thierry Lam

  I bought my PC brand new in mid-2006. I'm currently dual booting Win XP 32 bits and Ubuntu Karmic Desktop. Over the last few days, when I boot up my computer, it tells me that my bios time is not set. I now have 2 choices for booting in: Windows first: I can safely get into Windows but the date now shows 2002/01/01 at 00:00. From there, Windows will not sync its time to its servers, I have to manually advance the date myself. I can also advance the date from the bios at startup. Ubuntu first: Since the time date is still set at 2002, the boot system cannot find my linux partition. I can fix that issue by booting to Windows, set the date properly and the linux issue will be fixed automatically. The above two issues can also be fixed if I manually set the bios date/time manually when I turn on my computer. It's annoying to do that every single day since I shut down my PC daily. Am I having an OS issue or a hardware issue? How can I resolve this problem?
