• Sharing music on NAS with Zune and iPod?

  - by osij2is

  After being a long time iPod owner, I'm switching to the new Zune with its subscription model. I haven't bought a Zune yet but I'm planning on doing so within the next month or so. I have approximately 40GB worth of music and my girlfriend has her iPod music library around 30GB. I've been trying to figure out how to migrate all our music off of our laptops/desktops and centralize everything on my NAS. In sharing iPod music isn't too bad. Sharing from one machine to all is fairly easy within the iTunes player. As far as storing all the music on a NAS, again, iPods aren't too bad and imagine other systems aren't difficult. But I'm really new to the Zune and I'm beginning to run into some issues. My questions are: Is it possible to store all music from our iPods and Zune subscriptions and share music between the iPod/Zune within the same file share on my NAS? I'm sure it's possible to store music on a share, but I'm not sure how iTunes and the Zune software differs. Is there 3rd party software, maybe something like DoubleTwist that can sync based from NAS to multiple desktop/laptops? I've never used DoubleTwist but it's something that I found that looks close to being what I need. I've never quite done this myself so I'm trying to find a solution that can: a) store music on a network share; b) sync between different devices (Zune/iPod) seamlessly.

• 100% uptime for a web application

  - by Chris Lively

  We received an interesting "requirement" from a client today. They want 100% uptime with off-site failover on a web application. From our web application's viewpoint, this isn't an issue. It was designed to be able to scale out across multiple database servers, etc. However, from a networking issue I just can't seem to figure out how to make it work. In a nutshell, the application will live on servers within the client's network. It is accessed by both internal and external people. They want us to maintain an off-site copy of the system that in the event of a serious failure at their premises would immediately pick up and take over. Now we know there is absolutely no way to resolve it for internal people (carrier pigeon?), but they want the external users to not even notice. Quite frankly, I haven't the foggiest idea of how this might be possible. It seems that if they lose Internet connectivity then we would have to do a DNS change to forward traffic to the external machines... Which, of course, takes time. Ideas? UPDATE I had a discussion with the client today and they clarified on the issue. They stuck by the 100% number, saying the application should stay active even in the event of a flood. However, that requirement only kicks in if we host it for them. They said they would handle the uptime requirement if the application lives entirely on their servers. You can guess my response.

• How can I make the Firefox Password Manager more intelligent?

  - by Philip

  I have two major gripes about the FF password manager: If I restore a session with multiple tabs with sites with saved passwords, the master password prompt pops up once for each of them, even if I correctly enter the password the first time. Sometimes I want Firefox not to use my saved passwords at all (e.g. because I want to let someone else use it without getting access to my accounts), but hitting cancel results in erratic behavior--sometimes the box just pops up again and again, or sometimes it stops and behaves as I wish (continuing to browse w/o my passwords) until it encounters another site that wants my password. Thus even when hitting cancel does leave me free to browse passwordless, it doesn't get Firefox to leave me alone for the whole session. Thus: do you know of any tweak or add-on that could (1) make Firefox smart enough to get my master password once and then leave me alone, and/or (2) add an option (checkbox-style, toggle button, etc.) to browse "for now" (until I toggle the option) or even "for this session" (until I restart) without using any of my saved passwords? I'm running Firefox 3.5.6 on Mac OS X 10.5; thanks.

• ms excel 2010 in windows xp - when open workbook the data is formatted differently than when i saved it

  - by Justin

  I haven't been able to find an answer to this. I have multiple files that I use regularly in excel that now have cell formats of "date". Every single cell in the entire workbook (all sheets) is now formatted as "date". The problem is that I lost my formatting for percents, numbers years, etc and now everything is converted to date (xx/xx/xxxx). I am able to open previously saved versions of a file (prior to me having the problem) and the cells are formatted as I intend them to be (percents, numbers, general, as well as dates). Since this has happened on a couple different files recently, I am wondering how this is happening and how do I prevent it from happening in the future. I cannot cure the problem just by highlighting the entire sheet and converting back to general because I lose all my percents and number formatting. Example (Correct formatting): Month Year Working Days MTD POS Curr Rem May 2012 22 0 1,553,549 June 2012 22 0 1,516,903 June 2011 22 0 1,555,512 June 2010 22 0 1,584,704 Example (Incorrect formatting): Month Year Working Days MTD POS Curr Rem June Tuesday, July 04, 1905 Wednesday, January 04, 1900 Wednesday, January 18, 1900 213,320 July Tuesday, July 04, 1905 Wednesday, January 04, 1900 Monday, January 16, 1900 314,261 July Monday, July 03, 1905 Wednesday, January 04, 1900 Sunday, January 15, 1900 447,759 July Sunday, July 02, 1905 Wednesday, January 04, 1900 Monday, January 16, 1900 321,952 Sorry for the mess. Any suggestions?

• Outdoor WiFi Mesh Topology vs. Repeaters

  - by IronJaxor

  Here's the current configuration in our organization (which I believe is incorrect): We have a number of Cisco 1500 series AP's (22 in total), that are mounted outdoors to provide seamless WiFi coverage over a large area. Each AP however has its own physical ethernet connection back to the WLC (All the AP's are marked as Root AP's). They are all broadcasting the same SSID. We have tried to stagger the channel selection but because there are only three non-overlapping channels to choose from, and in some areas the density of AP's is quite high, there is multiple places of channel interference. With this configuration we experience 100-150 disconnects from clients every day. (Our clients are mobile so they move throughout the coverage area constantly). My idea is to switch the AP's to the same channel thereby forming a wireless mesh, use the built in functionality of the 1500 series to use 802.11a as the backhaul, designate one or two AP's as root AP's and wire them back to the WLC. Thereby forming a WiFi mesh, which if I'm not mistaken is the point of the 1500 series in the first place! I am however completely new at WiFi networks and wondering if I am simply mistaken in what I believe my proposed changes will enable, or if there is a better way to tackle the WiFi topology.

• Connecting a Wifi router to receivers with a cable instead of antenna?

  - by 31eee384

  This is a very strange question--I'd go so far as to say it's a stupid question. I'm being told that it is possible to, to describe it briefly, use a cable to connect an access point and a receiver directly to one another. This means that I would unscrew the access point's antenna, and attach one end of a cable to the port. Then, on the wireless receiver, I would also unscrew the antenna and plug in the other side of the cable. I'm being told the connection would work after this, just as a normal Wifi connection would. Bonus mini-question: if this works, would it still work if a splitter were attached to the access point and multiple receivers plugged in to the network? What would happen if I do this? Based on my surprisingly deficient knowledge of radio transmission, I don't think it would work. I would like some help knowing why it won't (or will) though, if possible. This is a somewhat hypothetical question--I realize that Ethernet does this exact job very handily, and I could just throw in a switch instead of the splitter. I simply feel that I should understand this scenario. Thanks for any help you can offer.

• Recover badly recorded DVDs

  - by CesarGon

  A few years ago (2003-2005) I bought a Sony USB external DVD recorder for my Dell laptop and I used it to burn a lot of discs. Much later, when I tried to use one of these discs, I realised that I could not read it. The disc behaved as if it was scratched or dirty. I tried on a couple of different DVD drives but got the same effect. Sadly, all the discs that I burnt with that recorder suffer from the same problem. Edit. When I read one of these discs with ImgBurn, I get lots of unrecovered read errors in multiple sectors, even at 1x speed. The sectors that cause read errors seem to be quite random; it's not always the same one. I have no idea what could be wrong with the discs. I doubt that they are scratched or dirty; it would be too much of a coincidence that all the discs that I burnt with that recorder got damaged at the same time. Also, they don't show any physical defects. Is there any way to diagnose what the problem is and, hopefully, recover the contents of the discs? Many thanks.

• How to deal with ssh's "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"?

  - by Vi.

  I often need to login to multiple remote stations that are just placed to the same static IPs for me. SSH complains about changed keys in this case: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... Offending RSA key in /home/vi/.ssh/known_hosts:70 ... I usually just run vim /home/vi/.ssh/known_hosts +70, dd wq and re-run the SSH command. How to do it simpler? Requirements: The warning should be displayed, and not like this: The authenticity of host '172.1.2.3 (172.1.2.3)' can't be established. It is easy to accept the key change. I expect something like this: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ... The fingerprint for the RSA key sent by the remote host is 82:cd:be:7a:ae:1b:91:2c:23:c1:74:4d:8a:38:10:32. Change the host key in /home/vi/.ssh/known_hosts (yes/no)? yes Warning: Changed host key for '172.1.2.3' (RSA) in the list of known hosts. [email protected]'s password: Simple and differs from usual "The authenticity of host can't be established." message.

• Computer randomly shuts itself off

  - by Decency

  I have not been able to determine a pattern for why this happens, despite my best efforts. I've attempted to run it on full power with Prime95 and this doesn't trigger a restart. Generally the restarts occur while I'm playing games, watching videos, or even just having multiple tabs open in a browser. However, I often play processor intense games for hours without any restarts occurring, and sometimes they'll happen 3-4 times in an hour during less intense activity, so I don't think that is the problem. I imagine it has something to do with overheating or power consumption so I've been monitoring CPU temperature and cleaning with compressed air, but the problem keeps happening. I don't know how to track power consumption, and assume that this is the problem. Whenever this occurs, the sound gets stuck in a short loop of whatever was playing at the time, though restarts also occur when nothing is playing. Here is a screenshot of temperatures: and under load: Here's the parts list: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=10546754 As shown in the list, the case includes a 585W Power Supply, which I've been told should be plenty. I built the computer myself with a friend's guidance but it's very possible I did something wrong. Right now I'm looking into ensuring that I have the latest drivers for all components. Any help would be appreciated- thanks.

• Windows Server 2008 IIS Random disconnect

  - by d123

  I am having a bit of a quirk with my IIS server. I'm running my IIS with 2 sets of IPs configured, one in the 192 range and the other in 172 range. I then have multiple apps which will talk to this server for information. Server has no AV or firewalls configured. I noticed that my apps when talking to the server on the 172 range, at random intervals, the server would just not respond. My apps would then disconnect and just try again, and every thing would be fine. This doesn't happen on the 192 range. So what I did is on a Linux box I did a watch command and to wget a file every half second on the 172 and 192 IPs. I noticed the same issue, every once in awhile wget on the 172 range would not get through, but there is no issues at all on 192. Thus I went around to Wireshark and did a dump. This is the last 3 packets, no other packets were received. 7010 100.871877 200.100.30.7 172.0.0.1 TCP 59619 http [ACK] Seq=140 Ack=85242 Win=64128 Len=0 TSV=1072818795 TSER=1660246133 7011 100.872238 200.100.30.7 172.0.0.1 TCP 59619 http [FIN, ACK] Seq=140 Ack=85242 Win=64128 Len=0 TSV=1072818796 TSER=1660246133 7013 100.873081 200.100.30.7 172.0.0.1 TCP 59619 http [ACK] Seq=141 Ack=85243 Win=64128 Len=0 TSV=1072818796 TSER=1660246133 So this is my issue, there is a random disconnect every once in awhile. The server doesn't receive the next SYN packet. HELP?

• McAfee ePolicy-Orchestrator (ePO) - policy ownership by groups?

  - by bkr

  Is there a way to grant ownership of an ePO policy to a group? Alternatively, is there a permission that can be set that would allow owners of an ePO policy to add other owners to that policy without making them ePO admin? In the case I'm looking at, ePO is deployed within a large heterogeneous organization with a large amount of delegation in the form of create/modify policy rights to allow multiple IT departments to customize to their needs for their sections of the system tree. The problem is that the policies are owned by the creator of the policy. This causes problems when they leave (staff turnover) or when other people on their teams need the ability to modify the existing policy. Unfortunately, as far as I can see, only someone who is an ePO admin can change the owners. Even the owner of the policy cannot add other owners (unless they are also an ePO admin). Ideally, I should be able to assign ownership of a policy to a group - since that would be easier to manage than me or another admin having to continually fix policy ownership or remove orphaned polices. Even just allowing the owners of the polices to add other owners would be sufficient. How are other people handling policy ownership when dealing with a large amount of delegated control of polices? Is there a way to delegate this out without making users full ePO admins?

• Interaction between two Clouds

  - by Snehal Masne

  I have setup the Cloud-A with 1 - [CLC+CC] and 2 - [NC] computers. I have another Cloud-B with same configuration. [using the Ubuntu Enterprise Cloud] Both of them working fine individually, in the same LAN. Now if I want to add the NC of Cloud-A to CC of Cloud-B, [in case the resources of Cloud-B are exhausted] how can I make it possible ? I guess this calls for the interoperability stuff... Could you please explain what happens exactly when we ask for instance, the direct interaction happens between the client and NC or it goes through the CLC and CC ? What I want to say is, say there are multiple cloud providers. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B. So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....? Please reply.. I am sorry if I'm doing mistake anywhere... Thanks in advance :) Regards, www.TechProceed.com

• Setup ejabberd with SQL Server 2008

  - by wonster

  Here's what I have got so far. Windows 2008 Server 64 bit. Installed the latest version of ejabberd, ejabberd-2.1.8-windows-installer.exe. The windows service starts up fine but seems ineffective. However, using the start & stop scripts work. I am able to login to the admin page which so far doesn't seem that versatile. Opened up ports 5222, 5226 and 5280 for my workstation to talk to the server. I've got Spark and Jabbear Windows clients to register, login and instant message with multiple accounts using the server. After confirming that I've got the very basics working, I've decided to make use of SQL Server 2008 as the database. Reason? Mainly, I am very comfortable with SQL Server. I can deal with redundancy, failover, data analysis easily. Not sure if ejabberd's built in DB provides all that. Following the instructions from ejabberd's documentation, I setup a system DSN that points to another physical database. The DSN checks out fine. (Tried both Named Pipes and TCP/IP) Modified ejabberd.cfg. Commented line %%{auth_method, internal} and uncommented line {auth_method, odbc} Uncommented and modified {odbc_server, "DSN=ejabberd;UID=somelogin;PWD=somepassword"}. After making these changes, I restarted. No errors are found in the log files. The jabber clients are no longer able to register new accounts. I'm not sure where to look for errors besides the /logs/ folder as I'm new to all this. I am basically stuck here on step 5. Has anyone got this setup to work recently? Some of the posts I've found around are years old and of no help. I can't be the only one setting up ejabberd with MS SQL. Any help would be appreciated!

• Blocking of certain file downloads

  - by Philip Fourie

  I have a problem where I cannot completely download a certain file from a server. The file is 1.9MB in size but only 68% is downloaded and then it hangs. I tried and these cases, which failed: Downloaded the file with HTTP Downloaded the file with FTP Moved the file to different FTP and web servers behind the ISA firewall Tried with IIS 6.0 & IIS 7.0 Multiple download clients. Which included FireFox, FileZilla (on Windows) and wget (on Linux) This worked: Downloading other files from the same location on the server. Both bigger and smaller and in size than the original. FTP and HTTP worked. Earlier version of this file (.DLL) works. It is as if the content of this file has an influence on this file being served. Network architecture: Client Machine - Internet (ISP) - ISA Server - IIS 7.0 The only constants are the ISP, Cisco router and the ISA server. Is it possible that something is rejecting the download because of the contents of the file? I am hoping ISA is the culprit... I am not a ISA expert is there somewhere I can look to establish if it is indeed ISA causing this? Update: Splitting the file into two parts with a hex editor results in one half of the file being served correctly and the other part not. Zipping the file results in the file being downloaded successfully. However this is not an option for this particular scenario. Renaming the file and its extension also doesn't work. Update 2009/10/22: It does NOT seems to be ISA that is causing this problem. We connected a laptop (running IIS) on an available public IP and still the file download to 68% before it hanged. The two remaining components are the ISP and the Cisco 800 series router. Anyone knows about an issue on the router perhaps?

• General guidelines / workflow to convert or transfer video "professionally"?

  - by cloneman

  I'm an IT "professional" who sometimes has to deal with small video conversion / video cutting projects, and I'd like to learn "the right way" to do this. Every time I search Google, there's always a disaster for weird, low-maturity trialware, or random forums threads from 3-4 years ago indicating various antiquated method to do it. The big question is the following: What are the "general" guidelines and tools to transcode video into some efficient (lossless?) intermediary, for editing purposes, for the purpose of eventually re-encoding it after? It seems to me like even the simplest of formats and tasks are a disaster of endless trial & error, or expertise only known by hardened experts who have a swiss army kife of weird conversion tools that they use, almost as if mounting an attack against the project. Here are a few cases in point: Simple VOB files extracted from DVD footage can't be imported into Adobe Premiere directly. Virtualdub is an old software people keep recommending but doesn't seem to support newer formats. I don't even know how to tell with certainty which codecs a video has, and weather the image is interlaced or not, and what resolution and codecs I'm dealing with. Problems: Choosing a wrong interlace option which diminishes quality Choosing a wrong pixel aspect ratio (stretches the image) Choosing a wrong "project type" in Premiere causing footage to require scaling Being forced to use some weird program that will have any number of negative effects What I'm looking for: Books or "Real knowledge" on format conversions, recognized tools, etc. that aren't some random forum guides on how to deal with video formats. Workflow guidelines on identifying a format going from one format to another without problems as mentioned above. Documentation on what programs like Adobe Premiere can and can't do with regards to formats, so that I don't use a wrench as a hammer. TL;DR How should you convert or "prepare" a video file to ensure it will be supported by Premiere for editing? Is premiere a suitable program to handle cropping, encoding, or should other tools be used for this, when making a video montage from a variety of source formats? What are some good books to read that specifically deal with converting videos that use any number of codecs?

• Linux Centos 6 becomes unavailable from time to time - OS&network issue

  - by adoado0

  I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

• Apache Named Virtual Hosts and HTTPS

  - by Freddie Witherden

  I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.

• How to perform this Windows 7 permissions change on many files via GUI or command line

  - by hippietrail

  After using my external hard drive on another Windows 7 computer to tweak photos with Windows Live Photo Gallery then upload them to Facebook I found the modified images were now not visible on the original Windows 7 computer. I'm not sure if the things I tried to get it working subsequently changed anything, but I do know this is the sequence of actions that makes the permissions of the modified files match those of the unmodified files: Right click on broken image file, select "Properties" On the "Security" tab press the "Advanced" button In the "Permissions" tab press the "Continue" button with the shield icon on it Tick the box marked "Include inheritable permissions from this object's parent Click the "Remove" button to remove the only current entry "Type: Allow, Name: Administrators (XYZ\Administrators), Permission: Full control, Inherited From: OK on the "Permissions" tab. OK on the "Security" tab. Now this same procedure does not work at the folder level. It results in "access denied" dialogs. I'm looking for some way to perform this exact modification on all the images I edited on the other computer. I'm happy to use the Windows GUI in Explorer or any other included tools. I'm happy to use the Windows command line. I'd prefer not to use a third-party tool since I'd have to be satisfied it's not doing anything else. I'm not looking for a different way to change permissions to other settings to make an external drive full of photos editable on multiple computers. At least not in this question.

• Remote Desktop Services Licensing - Does server have to have a RDS role?

  - by transistor1

  I recently set up a "micro" size Windows 2008 Datacenter server on Amazon AWS. My small group needs several concurrent RDS users to be able to access the machine. Without installing the "Remote Desktop Server" role, it allows 2 concurrent connections. I read on MS' website that in order to set up multiple users, we needed to install the RDS role. I did so, but now the application we are trying to share is running much slower than it was before. Prior to the role installation, it was taking about 5 seconds to open; now it is taking a few minutes to open -- without any other users logged on except me. My assumption is that the RDS role may be too much for this micro instance to handle, and currently, changing to another size instance is not an option (it may be possible later if we were to receive enough funding). This leads me to the following questions: 1) Is it a sensible assessment to assume that it is the RDS role is slowing things down, or are there other things that I could look at to speed it up? We are talking about a machine with ~600MB of memory. 2) If I revert back to the pre-RDS role, is there any legitimate way (in terms of purchasing RDS licenses) to get more than 2 concurrent desktops? I did read this, and am not questioning that the answerer is knowlegeable; but someone else may have some other experience. I am also making it clear that we want to do this in a legitimate way. Thanks in advance for any assistance that can be provided! EDIT: if it is helpful in answering the question, the application in question is a Lotus Approach database. Also, I am asking this from a technical perspective: not a legal one. I want to know if it is possible to install valid licenses without the RDS role.

• Synchronize folder on network, preserving hard links

  - by Waleed Hamra

  I have few computers using Windows XP Pro. I want to synchronize/back a folder from one machine, to another one. This far, It's a simple problem, and I've used FreeFileSync for such operations, with very satisfactory results. But, this all changes when hard links come into play. Today's folder contains lots of hard links, using such backup programs will result in hard links being treated as multiple files, and copied as such, greatly increasing folder size on destination, and defeating the purpose of using all these hard links in the first place. It gets more complicated when we take into consideration the fact that network shares on Windows DON'T expose hard linking facilities, meaning that running a hard-link-aware tool like rsync using --hard-links will be of no use. So my question, how can i backup my folder to the other computer, while preserving hard links? I don't mind installing 3rd party tools to do it, as obviously, the standard windows shares approach won't work... I am guessing there might be some tool that can be installed on both machines and works in a server/client mode? anyone has any idea how to do this?

• Can a OS be copied from one hard drive to another and still boot?

  - by AlexMorley-Finch

  Background My computer gets stuck on the make and model screen after the BIOS screen, aka the Toshiba screen. After some research I've realized that the problem is the hard drive. I'm using an old 250gb model that USED to be used for backup purposes, however I loaded windows 7 ultimate onto it This hard drive has trouble getting up to full RPM therefore cannot boot correctly until its warmed up. meaning that my pc needs to be restarted several times before it boots (once it took my 13 reboots to get my pc on!) From my research its either that, or lack of power supply, and I've tried multiple PSUs. Question I have my OS and all my files on this 250gb HDD... If I were to literally open the explorer, and copy EVERYTHING (including hidden files obviously) from this 250gb, to a spare 500gb I've got knocking about... Will it boot if I just copy everything? I cannot be bothered to load another OS onto my PC so if there is a way I can just copy the existing one over from one HDD to another and have it boot normally. This would be epic! I've heard about HDD cloning software. But before I purchase and/or download this software, I need to know if i can just copy the OS over through the windows explorer

• How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment

  - by user69508

  (Please forgive if this is posted in an incorrect forum. We didn’t know exactly where to post it.) We have an ASP.NET Web API single page application - a browser-based app running in IIS to serve up HTML5/CSS3/JavaScript, which talks to the ASP.NET Web API endpoint only to access a database and transfer JSON data. Everything is working great in our development environment - that is, we have one Visual Studio solution with an ASP.NET Web API project and two class library projects for data access. While development and testing on development boxes, using IIS Express to a localhost:port to run the site and access the Web API, everything is fine. Now we need to move it to a production environment (and we’re having problems - or just not understanding what needs to be done). The production environment is all internal (nothing will be exposed on the public Internet). There are two domains. One domain, the corporate domain, is where all users login normally. The other domain, the process domain, contains the SQL Server instance that our app and Web API will need to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. So, I guess what they want is: corp domain (end users) <– firewall (open port 80) <– DMZ (web server running IIS) <– firewall (open port 80 or 1433????) <– process domain (IIS for Web API and SQL Server) We’re developers and don’t really understand all the networking aspects, so we’re wondering how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code (HTML5/CSS3/JavaScript/images/etc.) is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Or, does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to "http://server/appname/api/getitmes"? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? I’m sure there are other questions, but we’ll start with these. Thanks!!! (Note: the servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.)

• Separate domains vs. one domain with alias-domains

  - by Quasdunk

  I have tried to ask this question a few days ago but I'm afraid it was not clear enough, so here's another try. I have set up a LAMP-server using ISPConfig 3 for the administration. PHP is running over Fast-CGI. I have several domains, like my_site.com, my_site.net and my_site.org, but they all point to the same application/website. Each domain has its own web-root-folder and is running under its own user. The application itself is in a common directory which is owned by another user, like so: # path to my_application (owned by web1) /var/www/clients/client1/web1/web/my_application/ # sym-link to my_application from my_site.com-web-root (owned by web5) /var/www/my_site.com/web -> /var/www/clients/client1/web1/web/ # sym-link to my_application from my_site.net (owned by web4) /var/www/my_site.net/web -> /var/www/clients/client1/web1/web/ With a setup like this I have encountered a few problems concerning the permissions when performing filesystem-operations with PHP. For instance, if the application is called via my_site.com, the user web5 is trying to write something to the application-folder. But the application-folder is owned by the user web1, so web5 is not allowed to write there. As far as I unterstand, this is how Fast-CGI works. After some research and asking a few people, the solution seems to be to break it all down to one domain (e.g. my_site.com) and define the other domains (my_site.org, my_site.net) as alias for this one domain. That way, there would be only one user who has all necessary permissions. However, this would mean that we'd have to buy a multidomain SSL-certificate - but we already have an SSL-certificate for each domain. We were able to use them with our previous provider (managed hosting), and there we also had only one web-directory and multiple domains. So if this was possible, I wonder: Is putting all the domains together into one v-host with one main- and several alias-domains the right approach in this case? Or may I have misunderstood something?

• How do you update without cutting off users?

  - by Griffin

  I searched around and I was surprised that I couldn't find an answer to this question. My assumption is that you have multiple servers. Normally they both will be doing their specific take (for the rest of this I will assume a simple website). Now lets say server A & B need updates. Do you update server A while server B keeps pushing out the webpage and then when server A is okay you update server B? This seems like it would work in small scale but seems horrible in large scale due to the fact that you'd need twice the power that you normally have. When dealing with a large number of servers do you update small sections at a time? I thought the problem with this would be if server A can't work alongside server B C D E or F any-longer that's not that bad. But when you start updating you slowly lose this small percentage. What is the proper way to deal with updates like this?
