• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.

• Why doesn't video run smoothly on my laptop anymore?

  - by andygrunt

  This might be an impossible question to answer remotely but I figure there may be some common causes that people can suggest so I think it's worth asking... Video no longer plays smoothly on my laptop. It used to but not for a while now. For example, playing a video on YouTube is pretty typical: I press play (making sure it's not on HD or even HQ) and the video buffers a little then starts to play. At first it plays fine then the video starts to stutter, turning into a slideshow while the sound continues to play smoothly. If I try playing the same video on my Playstation 3 (which is linked to the same network) it plays smoothly so it can't be the connection. Another example is streaming DivX videos. Again, I wait while it buffers and it starts but very soon, instead of a slideshow, this time the video just plays slowly while the sound continues as normal (instantly getting out of sync). Even if I let the video fully load before pressing play (i.e. it's no longer streaming), it still behaves the same way. I can even let it load 100% then save the file to hard disk and use VLC player to view it, and the same thing happens. I'm using an old laptop running Windows XP. For the past several years it's been connected to the router via Wi-Fi but in the past few days I've changed that to a network cable (like my PS3) but that hasn't helped. Yes, I regularly install various bits and pieces of software but nothing that I can identify as being the cause. So, are there known causes of this sort of behaviour and if so, what can I do to fix it? Thanks. Update to answer a few questions... Laptop Spec' (note: video has played back fine for the majority of time I've had the laptop) Toshiba Satellite 1900-603 (possibly called something else outside the UK) Intel Pentium 4 2.2 Ghz Processor Originally had 512Mb memory but recently doubled that to 1 Gig of memory Graphics: ATI Mobility Radeon 16Mb DDR VRAM Windows XP SP3 (Home edition) Over the years I've done several things to speed it up (disabling indexing etc) and am generally happy with the performance. I also regularly have a clear out of old software (if for no other reason than the laptop only has a 40Gb hard disk) and use CCleaner and Glary Utilities to strip out much of the crap from my system. Also recently (after doubling the memory), I've tried a few new things which might be likely candidates for slowing the video down such as Rocketdock, Jingle keyboard (which gives an old style 'clacky' typewriter sound when I type - love it), SugarSync, Taskbar Shuffle. However, the video doesn't play smoothly even when I try quit all these apps.

• SQL Clustering on Hyper V - is a cluster within a cluster a benefit.

  - by Chris W

  This is a re-hash of a question I asked a while back - after a consultant has come in firing ideas in to other teams in the department the whole issue has been raised again hence I'm looking for more detailed answers. We're intending to set-up a multi-instance SQL Cluster across a number of physical blades which will run a variety of different systems across each SQL instance. In general use there will be one virtual SQL instance running on each VM host. Again, in general operation each VM host will run on a dedicated underlying blade. The set-up should give us lots of flexibility for maintenance of any individual VM or underlying blade with all the SQL instances able to fail over as required. My original plan had been to do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Within the VMs - create a failover cluster and then install SQL Server clustering. The consultant has suggested that we instead do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Create a cluster on the HOST machines which will host all the VMs. Within the VMs - create a failover cluster and then install SQL Server clustering. The big difference is the addition of step 4 whereby we cluster all of the guest VMs as well. The argument is that it improves maintenance further since we have no ties at all between the SQL cluster and physical hardware. We can in theory live migrate the guest VMs around the hosts without affecting the SQL cluster at all so we for routine maintenance physical blades we move the SQL cluster around without interruption and without needing to failover. It sounds like a nice idea but I've not come across anything on the internet where people say they've done this and it works OK. Can I actually do the live migrations of the guests without the SQL Cluster hosted within them getting upset? Does anyone have any experience of this set up, good or bad? Are there some pros and cons that I've not considered? I appreciate that mirroring is also a valuable option to consider - in this case we're favouring clustering since it will do the whole of each instance and we have a good number of databases. Some DBs are for lumbering 3rd party systems that may not even work kindly with mirroring (and my understanding of clustering is that fail overs are completely transparent to the clients). Thanks.

• How to enjoy DVD on Apple iPad

  - by user44251

  I believe many people spent a sleepless night yesterday waiting for the new Apple Tablet to come, just a few days ago or perhaps longer I noticed fierce debate about it, its name, size, capacity, processor, main features, price etc. And now, they can take a long breath with the new Apple Tablet named iPad officially released on 28, January, 2010 (Beijing Time). But I know a new battle just begins. iPad, sounds somewhat like iPod and it really shares some similarities in terms of shape like smart, light and portable. It has a 9.7-inch, LED-backlit, IPS display with a remarkable precise Multi-Touch screen. And yet, at just 1.5 lbs and 0.5 inches thin, it's easy to carry and use everywhere. It can greatly facilitates your experience with the web, emails, photos and videos. Right now, it can run almost 140.000 of the apps on the Apple store. It can even run the apps you have downloaded for your iPhone or iPod touch. But so far, I haven't seen any possibility that it can work with DVD, probability there is no built-in DVD-ROM or DVD player which can play DVD directly. As Apple iPad states, the video formats supported are MPEG-4 (MP4, M4V), H.264, MOV etc and audio formats accepted are AAC, Proteceted AAC, MP3, AIFF and WAV etc, those are formats that are commonly used with iMac. This could really a hard nut to crack if you want to watch your favourite DVD on this magic Apple iPad. But don't worry, there is still way out, you just need a few steps for ripping and importing DVD movies to Apple iPad with a simple application DVD to iPad converter What's on DVD to iPad Converter for Mac DVD to iPad converter for Mac is a powerful and professional application designed for the newly released Apple iPad which can rip, convert your DVD contents to Apple iPad compatible MPEG-4 (MP4, M4V), H.264, MOV etc, and other popular file formats like AVI, WMV, MPG, MKV, VOB, 3GP, FLV etc can also be converted so that you can put on your portable devices like iPod, iPhone, iRiver, BlackBerry etc. Besides, it can also extract audio from DVD videos and save as MP3, AIFF, AAC, WAV etc. Mac DVD to iPad converter has also been enhanced that can run both on PowerPC and Intel (Snow Leopard included). It can offer versatile editing features which allows you to make your own DVD videos. For example, you can cut your DVD to whatever length you like by Trim, crop off unwanted parts from DVD clips by Crop, add special effect like Gray, Emboss and Old film to make your videos more artistic. Besides, its built-in merging feature and batch mode allows you to join several DVD clips into a single one and do batch conversion. And more features can be expected if you afford a few minutes to try.

• open source knowledge base CMS system

  - by Thomi

  I'm looking for an open source knowledge base system that uses tags, rather than free-text search to identify articles (a lot like serverfault does). I've looked at twiki, which many people suggested, but haven't found what I'm looking for. Basically I want to be able to create and tag articles, and provide an easy way for anonymous users to search based on tags. Edit: OK, here's some more detail regarding what I want. Basically, all the knowledge base systems I have seen so far are a collection of articles, each article with a title. Most of them allow you to categorise articles into groups and sub-groups. Users of the system can search for information using a title search, for example "How do I print from AwesomeProduct?" - which then shows a list of any articles that match that search text. This is fine and dandy when your KB is for one version of the software product (the mythical AwesomeProduct ver 1.0). However, the development team then go ahead and create a new version (ver 2.0) that adds many new features and changes some existing features. Now, how do we support both products in the same KB? The Naive method is to copy all articles from 1.0, and update them for 2.0, adding and removing articles in 2.0 as required. We can then add text at the top of every 1.0 article that says: "this articles applies to 1.0 only, to see the 2.0 version, click here" (or something similar) The problem with articles being indexed in the system by title is that it's very hard to filter based on meta-data like version. What happens when we create version 3.0 or 4.0? The end-situation here is that you have a mess of articles. They're hard to search, hard to filter, and even harder to manage. The solution (it seems to me) is to use tags, rather than text as the article index mechanism. So articles can be tagged with a tag representing the software version, topic area etc. etc. Users can then filter based on tag - an example search might be "version_1 printing" - which straight away gives a list of articles with all these tags. So that's what I'm looking for - a KB system that uses tags, rather than text to index many articles. I'm sure I could build something with drupal, but I was hoping for something that worked out-of-the-box.

• OpenVPN multiple servers on the same subnet, high availability

  - by andre

  Hey everyone. Let me start by saying that my Linux experience isn't super awesome but I can usually find my way around things easily. Over at work we have an OpenVPN setup that's been due for some improvement for a while now. The main server (tap mode) runs in our office, behind a rather slow DSL connection. The main problem is that, since I'm usually out of the office, every time I want to access something on the virtual network I have to go through that server to get anywhere else. We have two servers up on 100 Mbit connections that we use for development and production purposes, about 3 more servers in the office (one of them behind a different T1 line for VOIP) and about two dozen clients who use the network on a daily basis from various locations. We've had situations where network routing (outside of our control) would not allow people to reach our main OpenVPN server whilst the other locations were connectable. Also any time someone outside the office wants to fetch something from any of the servers (say, a 500 MB code repository), a whopping 20 KB/s download speed is just unacceptable these days (did I mention slow DSL? ok). We had to implement traffic shaping on this server since maxing out this connection was fairly trivial. I had the thought of running two (or more) OpenVPN servers in the network. These would have to have the same subnet though, as our application relies on virtual network's IP addresses for some of its core functionality. The clients would also preferably retain the same IP addresses but that's not vital. For simplicity, lets call the current server office and the second server I'm setting up, cloud. Call the server on the T1 phone. This proved to be rather complex because as soon as I connect to cloud, I cannot see office. Any routes to a server that would go through office also do not work while I'm connected to cloud (no ping, nothing) and vice-versa. There's no rules for iptables that would be blocking the traffic either. Recently I came across this article on linuxjournal but the solution they provide seems to only cover the use of two servers and somewhat outdated (can't even find much documentation, their wiki is offline). They also state that adding more servers would be a complex task. Ideally I would like to keep the existing server office running the virtual network and also run the OpenVPN daemon on the cloud and phone servers (100 Mbit and very reliable connection, respectively) so that we're on safe ground in case of a hardware failure, DSL failure, etc. So, in essence, I'm looking for a highly available OpenVPN solution (fix, patch, hack, tweak, whatever you want to call it) that will accept connections on multiple hosts (2 or more) whilst keeping the same IP address subnet regardless of the server to which you connect to. Thanks for reading and sorry for the long post, I hope it gets the point across :P

• Random Computer Crashes

  - by Josh W.

  Ok, here's a wierd one for you all. Occasionally my PC here at work will crash in a very peculiar way. My dual monitors will suddenly go blank as if there is no longer a video signal, the USB mouse light will go dark and mouse stays unresponsive, the keyboard lights will not change status when the appropriate keys are pressed (Num/Caps/Scoll Lock). The CD Tray WILL open and close. But the computer will not respond to a ping request. For all intents & purposes it's as if the computer is off, except it wasn't intentional by me. The power light and internal fans are still on and I've now lost any unsaved work. Now here's where it gets wierd. This PC is part of a batch of PC's we got from a local vendor who does our initial system builds. Mine, and 6 other co-workers PCs all have the same issue. Originally we thought it was a bad combination of hardware, but through trial and error the only thing we haven't eliminated are the OS, Mobo & CPU. The problem was so bad for some of them that they ended up going back to their 5 year old dinosaurs in order to get some work done, for me the problem isn't as bad, maybe once every other day or so, but still enough to bite me in the ass if I've forgotten my ritualistic pressing of CTRL-S every 1-5 minutes. In this case we've tried two different video cards, two different power supplies, two different memory configurations, running on a UPS/not on UPS, updating/rolling back video drivers, three different bios revisions. The only things we haven't swapped are the mobo & cpu, mainly because a new mobo means a new Hardware Abstraction Layer, ie re-install of windows and there's alot of other software on this PC that takes forever to reload by hand. There was a base image that our systems team created with all the drivers installed and the basic setup of software our company uses, but they then must customize the setup for us programmers so it takes a while to get a new configuration up and going. I'm a programmer by day and am usually pretty good at diagnosing computer problems whether through trial and error or not. We've pretty much exhausted all the ideas we can think of here, short of a new mobo/cpu. Was hoping someone out there might have anything else we can try..

• Nginx + Wordpress Multisite 3.4.2 + subdirectories + static pages and permalinks

  - by UrkoM

  I am trying to setup Wordpress Multisite, using subdirectories, with Nginx, php5-fpm, APC, and Batcache. As many other people, I am getting stuck in the rewrite rules for permalinks. I have followed these two guides, which seem to be as official as you can get: http://evansolomon.me/notes/faster-wordpress-multisite-nginx-batcache/ http://codex.wordpress.org/Nginx#WordPress_Multisite_Subdirectory_rules It is partially working: http://blog.ssis.edu.vn works. http://blog.ssis.edu.vn/umasse/ works. But other permalinks, like these two to a post or to a static page, don't work: http://blog.ssis.edu.vn/umasse/2008/12/12/hello-world-2/ http://blog.ssis.edu.vn/umasse/sample-page/ They either take you to a 404 error, or to some other blog! Here is my configuration: server { listen 80 default_server; server_name blog.ssis.edu.vn; root /var/www; access_log /var/log/nginx/blog-access.log; error_log /var/log/nginx/blog-error.log; location / { index index.php; try_files $uri $uri/ /index.php?$args; } # Add trailing slash to */wp-admin requests. rewrite /wp-admin$ $scheme://$host$uri/ permanent; # Add trailing slash to */username requests rewrite ^/[_0-9a-zA-Z-]+$ $scheme://$host$uri/ permanent; # Directives to send expires headers and turn off 404 error logging. location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ { expires 24h; log_not_found off; } # this prevents hidden files (beginning with a period) from being served location ~ /\. { access_log off; log_not_found off; deny all; } # Pass uploaded files to wp-includes/ms-files.php. rewrite /files/$ /index.php last; if ($uri !~ wp-content/plugins) { rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last; } # Rewrite multisite '.../wp-.*' and '.../*.php'. if (!-e $request_filename) { rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last; rewrite ^/[_0-9a-zA-Z-]+.*(/wp-admin/.*\.php)$ $1 last; rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last; } location ~ \.php$ { # Forbid PHP on upload dirs if ($uri ~ "uploads") { return 403; } client_max_body_size 25M; try_files $uri =404; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /etc/nginx/fastcgi_params; } } Any ideas are welcome!

• Computer freezes +/- 30 seconds, suspicion on SSD

  - by Robert vE

  My computer freezes for about 30 seconds, this happens occasionally. When it happens I can still move the mouse, sometimes even alternate between tabs in google chrome. If I try to open windows explorer nothing happens. Also chrome rapports "waiting for cache". It also happens in starcraft II, during which the sounds loops. I have made a Trace as this topic describes: How do I troubleshoot a Windows 7 freeze or slowness? Trace: https://docs.google.com/open?id=0B_VkKdh535p6NklhSDdBLURUMnc I have looked at it, but I couldn't figure it out. My system specs are: AMD Athlon X4 651 Asus Ati HD6670 ADATA SSD sp900 Asus f1a55 mainboard 4 GB crucial 1333 ram 500 watt atx ps I'm running Windows 7, fully updated. Any help is much appreciated. Update: I tried something before your reply that may have helped the problem. I don't know for sure if it has, it's too soon to tell. A bit of history first. I had problems installing win7 on my ssd from the start. In IDE mode it worked, but I had the same problems as above. AHCI was a total fail, with it on before install as well as turning it on after install (including tweaking register). I didn't bother installing the AMD chipset/AHCI as it was reported to have no TRIM function and thus make problems worse. Eventually I did install the AMD SMbus driver as the stability issues were driving me crazy. It worked, no more issues, until I installed some extra drivers and software. Audio/LAN/ASUS suite, I don’t see the relation, but somehow it screwed up my system again. As a last effort I posted here on this site. After which the thought occurred to me turn on AHCI again as by now I had all necessary drivers installed anyway. (plus all windows updates downloaded/installed in the meantime) I did and stability didn’t seem great the first few reboots, but eventually everything seemed to work great. I tried to play starcraft II – an almost guaranteed freeze before – and I had no problems. I’m basically crossing my fingers and hope the problem is gone for good. I still think it has something to do with my SSD. In my research into the problem I noticed a lot of these issues with sandforce 2281 firmware, the exact same firmware I have. People reported the same problem that I had, freezes. Additionally they reported that during a freeze the hdd light stayed on, I noticed after I read this that this happened with my computer as well. None of this is conclusive evidence that my SSD is really to fault, but it is suspicious. And why turning on AHCI would fix it I don’t know. Thank you Tom for taking a look, if the problem returns I will certainly do what you advised.

• Mysql Servers for Attendance System

  - by foo

  I'm building an attendance system. There are about 20 places where people will check in and check out using Mifare 1K Card. It will use MySQL as the database. The system will display something like "#ID IN: 800AM" when the first time the user checks in and "#ID OUT: 400PM" when the user checks out. For this to work, all the databases need to be synchronized with each other all the times. For an example, if user A went to location #1 to check in but by the time he wants to return home, the server at location #1 went down, he needs to go to location #2 or the nearest server to check out. The server at location #2 should display '#ID OUT: 400PM" and not "#ID IN: 400PM" since he's already checked in. So, what should I use to ensure this idea will work? My main concern is with the network (other department manages it) which is very unpredictable. It just love to go down anytime it wants to. Update LOL, didn't realize my question is not clear, just noticed it when you guys pointed it out, sorry about that. My real question is, how can I configure my MySQL to be synchronized with each other (20 servers)? MySQL cluster ? (tried reading about it, but I'm not sure if it's the right thing to do) My current setup (first phase): Local database for each server OS: Slackware A main server that keeps track which staff is at which server A web based front end for the user to see their history (which connects to the server based on their records) Main Pros No worries about network problems since it is a local database Main Cons A user can only check in and out at the same server. Databases/Servers are not connected with each others. Have to add the user to each server if the users want to check in at different locations. Which means, if he wants to go to location A, he must be checked out from location A first and then check in at location B. The server at location B didn't know that the user has checked in before at A. By the way, I've already centralized my NTP to a local server. About the network, let's just say, I don't have the authority to make changes so that the network will be better. The network won't effect all 20 servers at once, usually, just a few of them for several times a week. If there are anything else you would like me to answer, please just ask.

• Suspected network performance issue on VirtualBox Ubuntu guest on Win7 host

  - by Adam

  I set up Ubuntu 12.04 in VirtualBox on the Win7 machine I was allocated on my new project. I am running Java, Eclipse, Tomcat to develop a large data-intensive application and I noticed that this application runs at half the speed of my colleague's identical machine, where he runs it all under Windows. I think I have narrowed down the performance issue to the network, after comparing and equalising all the Java VM settings with my colleague. Is there a ping test I can do or some other network diagnostic test to flag up any problems? To give some background, the network performance is confusing. Running a network speed test to my colleague's machine with iperf shows speeds of 6 Mb/s from my Ubuntu guest, and 90 Mb/s from the win7 host. Large downloads, e.g. the Java SDK, come down at about 1.2 MB/s on both the guest and the host. Pings are sub-1ms on the host, but 1.5ms on the guest. I also did a broadband speed test, and got 10Mb/s download speed on both, but the host has an upload speed of 10Mb/s but the guest only uploads at 3Mb/s. I've been trying to diagnose any MTU problems with ping -M do to identify any kind of packet fragmentation problem but it's progressing very slow because I don't have much experience in this area. From what I read on other people's networking issues with VB and Linux guests on Win7 hosts, I should be able to get the speed on the guest up to the same level as the host. I installed a fresh VM with Ubuntu again to see if I'd foobar'd it somehow, but I'm getting the same readings with iperf on the virgin installation. My setup is: Adapter 1: Intel PRO/1000 MT Desktop (NAT) Adapter 2: ditto (host-only adapter) eth0 Link encap:Ethernet HWaddr 08:00:27:0b:76:bf inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe0b:76bf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:86236 errors:0 dropped:0 overruns:0 frame:0 TX packets:49369 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:69163946 (69.1 MB) TX bytes:3530535 (3.5 MB) eth2 Link encap:Ethernet HWaddr 08:00:27:a3:26:b8 inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fea3:26b8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:59 errors:0 dropped:0 overruns:0 frame:0 TX packets:57 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9148 (9.1 KB) TX bytes:7648 (7.6 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:701 errors:0 dropped:0 overruns:0 frame:0 TX packets:701 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:66321 (66.3 KB) TX bytes:66321 (66.3 KB)

• How to create NTFS partition in Linux to install Windows 7 from USB?

  - by Michal Stefanow

  I messed up with my computer and need help. Generally: install Windows 7 from USB. Problem: "setup was unable to create a new system partition" When first attempt to install Windows 7 failed I tried Linux live USB, installed distro to HDD, and erased all the existing partitions. Current state (fdisk -l): [writing from other computer so no copy and paste] /dev/sda1 305GB Linux /dev/sda2 7GB Extended /dev/sda5 7GB Linux Swam / Solaris To create a new, NTFS partition: fdisk /dev/sda n (for new) p (for primary) 3 (for partintion number) "No free sectors available" All the HDD was formatted couple of minutes before so there is a lot of free space but how to resize a parition? I cannot find an option for resizing in man fdisk. Some people say I should use gparted but my distro doesn't not contain this package. And my distro doesn't support wireless drivers so I have serious problems with downloading stuff. I tried also using cfdisk but any command results in: "cfdisk bad primary partition 1 partition ends in the final partial cylinder" I tried also removing partition 1 and then creating a new one (so there is no "no free sectors"). I'm receiving a warning: "Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table. The new table will be used at the next reboot." After restating: "grub rescue, no known filesystem" It may indicate that some changes have been made BUT when running Windows 7 installed some another error: "Windows cannot be installed to Disk 0 Partition 1" More detailed: "Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS." So formatting drive using Windows 7 installer BUT this time yet another error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information" Apparently I cannot access logs (how?) and I am back to drawing board with my live USB (this time showing partition as HPFS/NTFS). Any suggestions how to install Windows 7? Should I reinstall Linux to HDD, erase existing partitions once again, and use Parted rather than gparted (parted is included in the distro). Or maybe should I create another bootable USB such as PartedMagic to painlessly create partitions? I just want to install Windows 7 from USB, my laptop is semi-operational and I am ready to receive some help regarding fdisk and creating NTFS partitions. UPDATE: I did as suggested (removed all the partitions) and tried to install in unallocated space. Tried to create a new partition and format it. Same error: "setup was unable to create a new system partition" Came to the conclusion it may have something to do with TrueCrypt I have recently installed. Right now trying to FIX MBR (as I haven't got possibility to create rescue disc without optical drive)

• Can you set up a gaming LAN using OpenVPN installed in a VMware guest OS and be playing the game on the host OS?

  - by Coder

  I would like to setup a gaming VPN. Ie. I have some games that work over LAN and would like to play them with people that are not on my LAN. I know I can do this with OpenVPN. My ultimate goal would be to run OpenVPN portably on my host OS and not even need any virtualization. As such i don't want to install it on my host, but i'm fine with running it portably. I'm even fine with temporarily adding registry keys, and then running a .reg file to remove these entries once i'm done. To this effect i have installed OpenVPN on a virtual machine and diffed the registry. I then manually (using a .reg file) added all the keys that seem important on my host OS and copied the installation folder of OpenVPN onto my host machine. Then i try to run openVPN GUI 1.0.3 as a test and it says "Error opening registy for reading (HKLM\SOFTWARE\OpenVPN). OpenVPN is probably not installed". I verified that that key is indeed in the registry with all subkeys and it looks correct. I have tried running the GUI as an administrator and in compatibility mode with no success. I am running Windows 7. If this fails then i would be happy with installing OpenVPN on a virtual machine in VMWare but they key is that i will be running the game installed on my host machine. The first question for this option is if this is even possible. The second is, that I can't get the VM to have internet access if I use bridging but i can if i use NAT. Is it possible to do this game VPN setup with VMWare guest OS running using NAT? Summary of questions: -Is it possible to run openVPN portably and if so what did i miss above? -If it's not possible to run it portably, then can setup a gaming LAN by installing OpenVPN in a guest OS with NAT and how can i do this? -If the above is not possible then can i install OpenVPN in a guest using bridging and if so how can i set this up with a Windows 7 host and Windows XP guest as currently i can't get the guest to be able to access the internet in bridging mode, but it working in NAT mode. -In general is there any good documentation on setting up a gaming LAN with OpenVPN (i am using 2.1.4) as i have never set up a VPN of any sort before so any help would be much appreciated. Thanks!

• Triple (3) Monitors under Linux

  - by widgisoft

  I have a 3 monitor setup (each 1680x1050) via an Nvidia NVS440 (2 GPUs, 2 outputs per GPU totalling 4 outputs); this works fine under Windows XP,7 but caused considerable headaches under Linux (Ubuntu 9.04). I had previously used an XFX 9600GT and the onboard XFX 9300GS to produce the same result but the card was noisy and power hungry and I was hoping that there was some magical switch in the NVS4400 that got rid of this annoying problem - turns out the NVS440 is just 2 cards on one physical PCB :-p (I searched the net high and low for people using this card under Linux but found nothing, if anything the card uses less power and is fan less so I was to benefit from it either way) Anyway, using either set up there were 5 solutions available: Have 3 separate X instances, all un joined Have 3 separate X instances, adjoined by Xinerama Have 2 separate X instances - One using twin-view, both adjoined by Xinerama Have 2 separate X instances - One using twin-view but no Xinerama Have a single Twin-view setup and leave the 3rd screen unplugged :-p The 4rd option, using 2 separate X instances and twinview (but no xinerama) was the best balance in terms of performance and usability but caused 2 really annoying issues You couldn't control (without altering the shortcuts) which screen an application opened onto - and once it was opened you couldn't move it to another screen without opening up terminal and forcing it to move Nvidia's overriding or falsifying of Xinerama breaks and the 2 screens joined by Twin view behave like a single huge screen causing popups to open in the middle of both screens and maximising of windows stretches to the width of the first 2 screens Firefox can only run one instance as the same user so having multiple firefox windows requires at least 2 users The second option "feels" like the right option, but OpenGL is basically disabled and playing any sort of game or even running anything graphical causes a huge performance drop and instability - even trying to run a basic emulator for gba or gens just causes the system to fall over. It works just enough to stare at your desktop and do nothing but as soon as you start doing some work - opening windows, dragging things around - running multiple copies of firefox it just really feels slow. The last open, only going dual screen works perfectly and everything performs as required, full GPU acceleration - two logical screen spaces - perfect, just make it work across GPUs like windows! :-p Anyway, I know RandR was supposed to pick up the slack when it would introduced GPU objects of sorts to allow multiple GPUs to be stitched together to create one huge desktop at a much deeper layer than Xinerama. I was wondering if this has now been fixed (I noticed X server 1.7 is out) and whether anyone has got it running successfully? Again, my requirements are: One huge desktop to drag any window across Maximising of windows to each screen (as XP does) Running fullscreen apps on the primary screen and disabling the mouse from moving onto the others or on all 3 stretched Finally as a side note; I am aware of the Matrox triple (and dual) head splitter but even the price they go for on eBay is more than I can afford atm, my argument: I shouldn't have to buy extra hardware to get something to work on Linux when it's something that's existed in the windows world for a long time (can you tell I don't get on with X :-p); If I had the cash I'd have bought the latest version of this box already (the new version finally supports large resolutions as the displays I have 1680x1050 each).

• I have been told to accept one error with Memtest86+

  - by DustByte

  Bought a new computer back in August with 4x4 GB RAM. Had problems with the RAM. They sent me four new sticks, which also generated errors. Singled out four sticks (from the eight I now had) that didn't generate any errors. Discovered by coincident a new RAM error last week (this time no BSOD). Contacted the company. According to them there have been issues with a bad stock from last summer so I got two tested 8 GB sticks sent to me. Been running Memtest86+ over the weekend. After 20 hours I got an error (see attached photo). The test has now been running for 37 hours but so far only this one error. I contacted the company where I bought the computer. They wrote back: I wouldn't worry about hat one fail. We have had similar situations here whereby it passes numerous times but then fails once. We think it's an issue with memtest, after all memory is faulty or it isn't so you can't really have it pass a few times, fail the next time around and then pass again! Please trust me on this and continue with the memory we sent you and if your problems continue we'll look at getting it replaced again. I gather from other forum posts that many people do not accept a single error. What could this single error signify, faulty RAM or a glitch in the MEMTEST program (or other)? Update: From the helpful comments below I conclude that an occasional (and rare) "random" error could occur and be acceptable, but repeated errors at the same address would indicate malfunction. Memtest has now run for 45 hours and I still have only one error. For everyone's information, I will keep running the test. In less than two days I am going away for a month. I will most likely leave Memtest running. As I do not have a UPS there is a risk that a power outage will ruin the experiment. The computer is a desktop so I cannot bring it with me (which would curiously have exposed it to more cosmic rays as I will be flying ;)).

• ASA5505 Novice. Setting up Outside/Inside/and DMZ as Guest Network

  - by GriffJ

  I need a little help in developing a config for our ASA5505. I'm an MCSA/MCITPAS but I don't have a lot of practical cisco experience. Here is what I need help with, we currently have a PIX as our boarder gateway and well it's antiquated and it only has a 50 user license which means I'm constantly clearing local-host throughout the day as people complain. I discovered that the last IT person bought at couple ASA5505s and they've been sitting in the back of a cupboard. So far I've duplicated the configuration from the pix to the asa but as I was going to be going this far I thought I'd go further and remove another old cisco router that was used only for the guest network, I know the asa can do both jobs. So I'm going to paste a scenario I wrote up with the actual IPs changed to protect the innocent. ... Outside Network: 1.2.3.10 255.255.255.248 (we have a /29) Inside Network: 10.10.36.0 255.255.252.0 DMZ Network: 192.168.15.0 255.255.255.0 Outside Network on e0/0 DMZ Network on e0/1 Inside Network on e0/2-7 DMZ Network has DHCPD Enabled. DMZ DHCPD Pool is 192.168.15.50-192.168.15.250 DMZ Network needs to be able to see DNS on Inside Network at 10.10.37.11 and 10.10.37.12 DMZ Network needs to be able to access webmail on inside network at 10.10.37.15 DMZ Network needs to be able to access business website on inside network at 10.10.37.17 DMZ Network needs to be able to access the outside network (access to the internet). Inside Network has NO DHCPD. (dhcp is handled by domain controller) Inside Network needs to be able to see anything on the DMZ network. Inside Network needs to be able to access the outside network (access to the internet). There is some access-list stuff already, some static mapping already. Maps external IPs from our ISP to our inside server IPs static (inside,outside) 1.2.3.11 10.10.37.15 netmask 255.255.255.255 static (inside,outside) 1.2.3.12 10.10.37.17 netmask 255.255.255.255 static (inside,outside) 1.2.3.13 10.10.37.20 netmask 255.255.255.255 Allows access to our Webserver/Mailserver/VPN from the Outside. access-list 108 permit tcp any host 1.2.3.11 eq https access-list 108 permit tcp any host 1.2.3.11 eq smtp access-list 108 permit tcp any host 1.2.3.11 eq 993 access-list 108 permit tcp any host 1.2.3.11 eq 465 access-list 108 permit tcp any host 1.2.3.12 eq www access-list 108 permit tcp any host 1.2.3.12 eq https access-list 108 permit tcp any host 1.2.3.13 eq pptp Here is all the NAT and route stuff I have so far. global (outside) 1 interface global (outside) 2 1.2.3.11-1.2.3.14 netmask 255.255.255.248 nat (inside) 1 0.0.0.0 0.0.0.0 nat (dmz) 1 0.0.0.0 0.0.0.0 route outside 0.0.0.0 0.0.0.0 1.2.3.9 1

• Educate me - should I buy these prebuilt NAS (which is better) or make my own?

  - by user29336

  I'm trying to learn as much as possible, and I think I've learned quite a bit so bear with me here under my confusion. I found a coupe NAS setups. I'm not sure if one is better than the other, other than the price being higher on some, and some coming with drives VS not. Let me list my setup so you can get an idea of what I want to provide: Macbook Pro Macbook Mini for Media streaming (so far) Windows 7 Gaming Computer Xbox 360 I'd like to provide a storage system for all these devices so they can access files very easily, I'd also like any of these devices to be able to stream media from this storage system. I'd like this storage system to be hassle free in terms of my confidence in the data integrity. If a drive fails, I want to know that I can replace the drive and all my files will still exist. I'd like to access this storage system OUTSIDE of my LAN. If I'm out on a job for work I'd like to go in, or be able to have people DL some files. This brings me to a question, is this what iSCSI is? I'd like this data system to be able to download torrents. I want to mount any drive on this storage system onto my OSX laptop as if it were a local drive attached. (Is this with iSCSI is?) I'd like this system to have a GOOD web based GUI. I don't want to install software to use it. I believe those are the most of my requirements. If I'm missing something that I have no knowledge about, can someone educate me? Here are the systems I found: $729ish on Newegg Lacie 5Big Network 2 (comes with 5TB of space. iSCSI / mac compatible, torrents, nice ui, + others?) Is this overpriced for what it provides? It almost seems like a great deal to me because of the 5TB of space it comes with vs the other NAS systems that don't come with storage but cost $600-700. Should I get a different NAS system? Netgear? Others? Do they have same features? Better? Is it better to buy your own disks? What about making my own? I'm tech savy all around. It seems cheaper to buy a premade one especially with the support/warranty it provides...

• Localhost has just stopped working (using xampp)

  - by Joe Taylor

  I installed Xampp to use for local development of a Drupal site. Its been working fine out of the box until now. The main Xampp localhost welcome menu loads, however my subdirectory (localhost/drupal) doesn't. It just spins in the browser for ages and nothing happens. Just a blank screen. I've tried the edit people suggest in the hosts file but that hasn't work and I'm getting no errors so not sure what to do. Anyone have any ideas what might be wrong?

• Windows server detected error with hard disk

  - by user53864

  We have hosting Windows server 2008 R2 and I am working as admin in small company. The server is hanging and restarting as the hard disk seems to be damaged due to power fluctutaion(though having inverter) as it's showing the below error message on server reboot: Problem detected with the hard disk Press any key to continue It's Seagate 1TB SATA hard disk and it's booting after pressing enter. So it's clear that the hard disk is dying. Yes, it's in warranty but it's fact that warranty won't recover the lincesed windows server 2008 and it's data. As it's booting now, I backed up required things and I am thinking to clone the entire hard disk. The first thing it striked me is checking on the Seagate site if any tool available for cloning and I found Seagate DiskWizard but not specified it for windows server 2008. Please anybody could help me giving your best ideas for the below: Urgently, What's the best way(free of cost) for me to clone in my case with the new same sized hard disk? It's a one time lincenced and I cannot use the same key again if I reinstall the server. Will the lincense be carried with new disk if cloned? else there is a way to contact Microsoft explaining the problem occurred, to obtain new key for no charge?. I want to take measure for future. How do I keep two disks in continuous sync? mirrored & raid are the only options converting the disks to dynamic? or is there a best way I could do with no additional charge?. Any help is greatly appreciated. Thank you! EDIT:1 I started cloning the disk with CloneZilla and it was going proper showing in GUI. But after some time there is no GUI but a black screen with some codes(looks like disk location numbers) going page by page(I have attached the screenshots below captured from my phone). Do you people think it's actually cloning?. I started in the morning and it's evening now. I left the office now to let it finish what it's trying to do and I'll go & check it tomorrow. Slowly lost hope, don't know what face it's going to show tomorrow. Any ideas?

• Secure copy uucp style

  - by Alexander Janssen

  I often have the case that I have to make a lot of hops to the remote host, just because there is no direct routing between my client and the remote host. When I need to copy files from a remote host two or more hops away, I always have to: client$ ssh host1 host1$ ssh host2 host2$ scp host3:/myfile . host2$ exit host1$ scp host2:myfile . host1$ exit client$ scp host1:myfile . Back when uucp still was being used this would be as simple as a uucp host1!host2!host3 /myfile . I know that there's uucp over ssh, but unfortunately I don't have the proper privileges on those machines to set it up. Also, I'm not sure if I really want to fiddle around with customer's machines. Does anyone know of a method doing this tasks without the need to setup a lot of tunnels or deploying new software to remote hosts? Maybe some kind of recursive script which clones itself to all the remote hosts, doing the hard work for me? Assume that authentication takes place with public keys and that all hosts do SSH Agent Forwarding. Edit: I'm not looking for a way to automatically forwarding my interactive sesssion to the nexthop host. I want a solution to copy files bangpath-style using scp via multiple hops without the need to install uucp on any of those machines. I don't have the (legal) rights or the privileges to make permanent changes to the ssh-config. Also, I'm sharing this username and hosts with a lot of other people. I'm willing to hack up my own script, but I wanted to know if anyone knows something which already does it. Minimum-invasive changes to hosts on the bangpath, simple invocation from the client. Edit 2: To give you an impression of how it's properly been done in interactive sessions, have a look at the GXPC clustershell. This is basically a Python-script, which spwans itself over to all remote hosts which have connectivity and where your ssh-key is installed. The great thing about it is, that you can tell "I can reach HostC via HostB via HostA." It just works. I want to have this for scp.

• Dlink search is hijacking my browser

  - by James

  For months now "DLink search" has been hijacking my search engines. I use google chrome, and I have organized my search engines in the handy dandy "manage search engines" tool about a TRILLION times. It never even says D-link is hacking my search engines. It does not show up! I have read many posts on this forum and others saying that to fix this problem from internet explorer: Setup, internet options, yadayada, magical fairies, and you are solved, but my browser is google chrome! How am I supposed to do this from there! I do not know how to re-setup my Dlink router, which is the cause of the problem! HOW? In those posts with the magical fairies fixing it, HUNDREDS responded saying, "yep, those fairies definitely fixed it right. :)" These people were so satisfied. IT WORKED FOR THEM, WHY NOT ME. I look at it and go ":(" because it does not help me. There are no options for anything to do with this in GOOGLE chrome. PLEASE EXPLAIN and HELP. I see no "SETUP" option, no "Internet Options" button, no anything. BTW the exact posts are these: "Uncheck Advanced DNS in the router internet setup. This will take care of it. I had this problem with my DLink router before." "I had this issue with my DIR-655 and unchecking the Advanced DNS setting in Setup - Internet - Manual Internet Connection Setup fixed it." "If this is just internet explorer, you can go to Tools Internet Options or Internet Options in Control Panel. From here, go to the advanced tab and click the Reset button." "I would set the router's DNS to a site like OpenDNS, and I would ensure the machines are set to get their DNS settings via DHCP or set the machine's DNS setting to OpenDNS. If the router's DNS looks like it was messed with, some bad software know the default passwords for routers and could have changed it. If you don't already I would make sure the password to the router is not default or easy to guess. I've had spyware change a machine's DNS, but the fact it is happening on all machines makes me wonder if it is the router." "Something got into your router and changed the dns server most likely, do a hard reset of the router and then change the password to something strong. Also check for a firmware update for the router and apply it as soon as possible."

• Setting up Virtual Hosts with Apache on Windows 2008 server for multiple sites. Complicated setup, including subversion

  - by Roeland

  I am setting up apache on my windows 2008 server at my home. It will serve 2 functions. Subversion hosting to allow me and some others to manage company documents with version control Local website hosting for web development. Will need to run several websites since I generally work on more then one site at a time. Heres what I have done so far. I set up subversion and apache 2.2 using some walk troughs. I changed the default port to 1337. (im a nerd) Using dyndns.com I created a domain to forward to my home ip which is dynamic. ( company.gotdns.org) I then went into my DNS for my company.com and added a record to point repo.company.com to company.gotdns.org At this point people who need access to my file repository can access by going to repo.company.com/repo which is good so far. My question comes on the next step, setting up virtual hosts with apache. Ideally I would like to have my local website be viewable by some others in the company from their homes. So, say I am working on site1, I would like to have them be able to view this by going site1.roeland.bythepixel.com. At the same time, I would like to have site10.wouter.bythepixel.com go to his local setup for site10. What I have done for this: I went into my DNS for company.com and added a record to point roeland.company.com to company.gotdns.org (which translates to my ip). I added code to my httpd-vhosts.conf (listed at bottom) I added code to my host file (listed at bottom) Hah, so of course this doenst work as excepted.. going to site1.roeland.bythepixel.com doesnt bring up my test1 site. Could anyone point me where I may be going wrong? Thanks! hosts: 127.0.0.1 localhost 127.0.0.1 sensenich.roeland.bythepixel.com ::1 localhost httpd-vhosts.conf: <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "F:/Current Projects/sensenich.com" ServerName sensenich.roeland.bythepixel.com ErrorLog "logs/sensenich.roeland.bythepixel.com-error.log" CustomLog "logs/sensenich.roeland.bythepixel.com-access.log" common </VirtualHost>

• 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?

• If Nvidia Shield can stream a game via wifi, why can I not do the same via ethernet to any other PC?

  - by Enigma

  I think it absurd that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth. I can only assume that there must be some reason behind this or a limitation preventing this, but what? 150mbps wifi is in no way superior to a 1000mbps LAN connection aside from well wireless mobility. Not only that but I have a secondary laptop and desktop which should by hardware comparison completely outperform anything the Tegra in the Nvidia Shield can do. Is this all just a marketing scheme to force people to buy the shield for the streaming benefit? Chief among these is that NVIDIA’s Shield handheld game console will be getting a microconsole-like mode, dubbed “Shield Console Mode”, that will allow the handheld to be converted into a more traditional TV-connected console. In console mode Shield can be controlled with a Bluetooth controller, and in accordance with the higher resolution of TVs will accept 1080p game streaming from a suitably equipped PC, versus 720p in handheld mode. With that said 1080p streaming will require additional bandwidth, and while 720p can be done over WiFi NVIDIA will be requiring a hardline GigE connection for 1080p streaming (note that Shield doesn’t have Ethernet, so this is presumably being done over USB). Streaming aside, in console mode Shield will also support its traditional local gaming/application functionality. - http://www.anandtech.com/show/7435/nvidia-consolidates-game-streaming-tech-under-gamestream-brand-announces-shield-console-mode ^ This is not acceptable for me for a number of reasons not to mention the ridiculousness of having a little screen+controller unit sitting there while using a secondary controller and screen instead. That kind of redundant absurdity exemplifies how wrong of a solution that is. They need a second product for this solution without the screen or controller for it to make sense... at which point your just buying a little computer that does what most other larger computers do better. All that is required, by my understanding, is the ability to decode H.264 video compression and transmit control/feedback so by any logical comparison, one (Nvidia especially) should have no difficulty in creating an application for PC's (win32/64 environment) that does the exact same thing their android app does. I have 2 video cards capable of streaming (encoding) H.264 so by right they must be capable of decoding it I would think. I haven't found anything stating plans to allow non-shield owners to do this. Can a third party create this software or does it hinge on some limitation that only Nvidia can overcome? (*) - perhaps this isn't the first but afaik it is the first complete package.

• Reviews Cheyney Group Marketing: What accounting softwares are available in the market for small businesses?

  - by user225556

  Accounting is the language of business, and good accounting software can save you hundreds of hours at the business equivalent of Berlitz. There's no substitute for an accounting pro who knows the ins and outs of tax law, but today's desktop packages can help you with everything from routine bookkeeping to payroll, taxes, and planning. Each package also produces files that you can hand off to an accountant as needed. Small-business managers have more accounting software options than ever, including subscription Web-based options that don't require their users to install or update software. Many businesses, however--including those that need to track large inventories or client databases, and those that prefer not to entrust their data to the cloud--may be happier with a desktop tool. We looked at three general-purpose, small-business accounting packages: Acclivity AccountEdgePro 2012 (both the product and the company were previously called MYOB), Intuit QuickBooks Premier 2012, and Sage's Sage 50 Complete 2013 (the successor to Peachtree Complete). All three packages offer a solid array of tools for tracking income and expenses, invoicing, managing payroll, and creating reports. These full-featured and highly mature programs don't come cheap. Acclivity AccountEdge Pro, at $299, is the least expensive; and prices climb if you opt to use common time-saving add-ons such as payroll services, or if you add licenses for multiple user accounts. All three are solid on the basics, but they have distinct differences in style and focus. The more you know about your accounting requirements, the more closely you'll want to look at the software you're thinking of buying. Sage 50 Complete should appeal most to people who understand the fine points of accounting and can use the product's many customization features (especially for businesses that manage inventory). QuickBooks works hard to appeal to newbies who need only the basics and might be intimidated by the level of detail and technical language exposed in the other two packages. At the same time, it also has a slew of third-party add-ons that meet specific needs and greatly expand its capabilities. AccountEdge Pro balances accessibility with a strong feature set at an affordable price. It's especially suitable for businesses that need to provide simultaneous access to multiple users.
