• Imac g5 with no OS nor CD drive

  - by sinekonata

  What I want: Ubuntu on a g5 Imac. What I have: An empty PC (Intel g5 17" Imac) with broken CD drive. Its model is A1173. This PC with Ubuntu 12.04 and an old Vista partition. a usb flash drive. Problems: No CD means the only boot Drive I could use is USB. There are no BIOS on Macs so I can't set boot settings or even see if it detects my USB drive. When I start the machine and press ALT the first and only thing I see is an old corrupted winXP partition and not a single option or additional information. So assuming blindly that the Mac hardware/firmware works normally, I don't have any Mac OS to use any of the tools that I found on different tutorials for building a bootable .img drive for macs. I can't find much software on Linux/Windows to substitute to those tools, for example among others converting an .iso file (win/linux) to .img (mac I guess). Which makes me think that the scenario where someone like me has Mac hardware but no Mac OS is extremely rare. So other than finding someone that has a Mac I have no solution. So I ask what would you do? the only thing is it should not involve any money (I know mac soft is rarely free) which also excludes getting any MacOS unless I can use a free macos.img for VM or restore the original Mac for free. Thank you

• How to use a common library of environment variables among different languages?

  - by JDS

  We have three main languages with which we perform system tasks: Bash, Ruby, and PHP, and Perl. Four, four main languages. We use managed environment variables to provide authorization info that automated scripts need. For example, a mysql user account and password. We'd like to use one single managed file to maintain these variables. In some instances, for example, in cron, these environment variables are not available. They are made available in CLI scripts because we source the env file in everyone's profile. But something like cron doesn't do that. On the CLI, when the env file is sourced, any given script can access those variables. Bash has them directly, PHP in $_ENV, ruby in ENV, etc. We can't source the file into non-Bash scripts, because most languages implement shell commands by running them in a subshell. We considered parsing the Bash, converting to the script's lang, and running the equivalent of "exec(parsed_output)" on the resulting strings. What is a good solution to providing managed environment vars to scripts running in cron, or similar?

• processes slow after some time of actively running

  - by Yervand Aghababyan

  i have several cron jobs running on an ubuntu machine. each one does some pretty heavy load stuff. The cron jobs are parsing files and the bigger the file the longer it takes them to parse it. The strange thing is that if i make the files too big ( like 30mb) the script kind of hangs. It starts processing them really enthusiastically but after some time (something like 5-10 minutes) the cpu usage of the process drops a lot and it gets into some "zombie" state. If prior to this the process in htop was using 70-80% of the CPU then after this drop occurs it slows down to something like 5-10%. the load average drops down as well. The status of the processes sometimes changes to D in htop, which AFAIR stands for zombie. Today i noticed the same behavior of processes of mysql when executing heavy queries (a query took something like 4 hours to execute). the cron jobs are mostly php and during their processing most of the CPU eats the php process and not mysql. so i think the issue is not with a specific language/program but with the way the processes are "managed". The only other place i've seen similar behavior was on my Amazon EC2 micro instance when after some aggressive use of CPU the CPU quota was taking effect and everything was slowing down dramatically. This is a dedicated machine running ubuntu. what may be the cause?

• Does a VPN requirement kill the concept of having a Web Application in the Cloud?

  - by Christian

  Recently I posted a question in SO, but so far I got no answers. I wonder if I'm asking the wrong question. This is the problem: We need to design an application which offers a public http web service, but at the same time it must consume some services through a VPN connection from other existing company. There is no other alternative but to use a VPN connection to access those services. We want to host our application in some cloud infrastructure like Heroku or Amazon EC2. But there is no direct way to access the VPN services of the other company from there. The solution I'm thinking, but I don't like is to have a different server to expose the services from that VPN. But this will require the setup of another server which I prefer to avoid. In the case this is the solution, can I use an Amazon EC2 instance to connect to a VPN? This is what I was thinking, is it correct? I don't have experience using VPNs, tunnels or those kind of networking stuff. I will really appreciate if you can propose me an alternative solution, or just give me a comment.

• xcopy Not Surpressing File/Directory Query

  - by Daniel Bingham

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

• How to remotely connect using perfmon?

  - by user36914

  Suprised there is not a ton of information on google when i search for this but there is not. Lot of people asking the question but i none of them have any good answers. I have a remote computer running hyper-v (server) running a Windows 7 x64 guest (guest). Occasionally i won't be able to remote desktop to guest. I will then remote to server and see that the guest instance is constantly using about 25% of the cpu. WHen i try to connect directly from server i will get the login screen but as soon as i type the password in it will just stay at the windows 7 login screen but the account names will disappear and it will not log in. It responds to pings though. I don't know how else to diagnose other than trying to run perfmon remotely. It only happens like every 3 weeks and i run it 24/7. So i'm trying to run remote desktop remotely. I tested this out on a local vm i have running under vmware. When i try to connect using perfmon to my local vm i get this error: "when attempting to connect to the remote computer the4 following system error occurred: the network path was not found" I found in another past to start the remote registry service and when i start the service i get this error: "No such interface supported" Anyways, how do i remotely connect to another machine with perfmon or if anyone has a better idea how i can diagnose the problem above then let me know.

• unable to access Internet by wireless but can by cable

  - by Jeff King

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

• How can I create a VLAN on my extreme switch for a separate subnet/domain?

  - by drpcken

  I'm putting together a small active directory implementation for a buddy of mine. I currently have 2 servers (one is the primary domain controller) and a couple clients. I need to test and run updates on every machine on this domain, but I would have plug them into my current LIVE domain to get it internet access. From what I've read having two separate domains on a single subnet is a bad idea (even though it is temporary) so I don't want to risk messing anything up on my production domain. I'm pretty sure I can create a separate VLAN on my extreme 48 port switch and plug this smaller domain into it on a different subnet, but I don't know the commands. Both subnets would need internet access of course (one of the things I can't wrap my head around is routing internet traffic between subnets (gateway is on production subnet). Switch is a Summit x450e-48p My production domain is on subnet 192.168.200.0. My new domain I want to put online would go into subnet 192.168.10.0. A shove in the right direction would be greatly appreciated. Thank you!

• What are these isolated resource requests in Apache's access_log?

  - by Greg

  I was looking at my Apache access log and came across some strange requests. A single IP address will access several resources (mostly css style sheets and images), but no actual pages. Sometimes they are requesting a resource that no longer exists on the server, or one that is still under the web root but no longer used (e.g. a resource in an old WordPress theme). Also: The requests list no referrer I get no useful information on the IP address by looking it up There doesn't seem to be any pattern among the IP addresses that are making these requests (e.g. different countries) Are these just links from a stale cache somewhere? Could it be a sign of an attack of some sort? Here is a typical example: GET /wp-content/themes/my-theme/images/old-image.gif HTTP/1.1" 500 809 "-" "Mozilla/4.0 (compatible;)" This was one of about 10 similar requests, some for existing resources, some for older resources. There is no other sign of this IP address in access_log. Note the internal server error, which is a topic for a different thread. What I'm asking here is where would isolated requests like this come from?

• Time Machine is getting stuck at "Preparing to Back Up" and my Trash isn't emptying

  - by zarose

  I have encountered two separate problems, but I am putting them in the same question in case they are related. First, my Trash would not empty. It seems to be getting stuck on certain files, because I will reset my Macbook and some of the files will be deleted, and then if I remove a file or two at random, more can be deleted. Some of these files had strange characters in their names. I tried changing the names to single characters, but this did not help. Next, I attempted to backup my Macbook using Time Machine. I plugged in the HDD I've been using for this, but every time I try to start the backup, Time Machine gets stuck at "Preparing to Back Up". I definitely need to know how to fix the Time Machine problem, but I am curious how to solve the trash problem as well, and whether or not these problems are related. EDIT: Console.app logged the following this morning before I left on a trip. I did not bring the HDD with me. 6/5/12 7:41:28.312 AM com.apple.backupd: Starting standard backup 6/5/12 7:41:46.877 AM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 7:41:58.368 AM com.apple.backupd: Backup failed with error: 19 6/5/12 7:59:08.999 AM com.apple.backupd: Starting standard backup 6/5/12 7:59:10.187 AM com.apple.backupd: Backing up to: /Volumes/Seagate 3TB Mac/Backups.backupdb 6/5/12 7:59:13.308 AM com.apple.backupd: Event store UUIDs don't match for volume: Macintosh HD 6/5/12 7:59:13.331 AM com.apple.backupd: Event store UUIDs don't match for volume: Blank 6/5/12 7:59:13.683 AM com.apple.backupd: Deep event scan at path:/ reason:must scan subdirs|new event db| 6/5/12 8:23:31.807 AM com.apple.backupd: Backup canceled. 6/5/12 8:23:33.373 AM com.apple.backupd: Stopping backup to allow backup destination disk to be unmounted or ejected. 6/5/12 9:51:21.572 PM com.apple.backupd: Starting standard backup 6/5/12 9:51:22.515 PM com.apple.backupd: Error -35 while resolving alias to backup target 6/5/12 9:51:32.741 PM com.apple.backupd: Backup failed with error: 19

• Windows 7: L10N mechanics

  - by John Sonderson

  I have a localized version of Windows 7. I can't figure out where windows gets the names for files and directories on the system. For instance, consider the following (default) files. > cd C:\Users\Public\Pictures\Sample Pictures > dir Chrysanthemum.jpg Desert.jpg ... When I view these files on the default file explorer I see these names: Crisantemo.jpg Deserto.jpg ... This seems to imply that each file can be somehow assigned a localized name somewhere. However I cannot figure out how. Would appreciate if someone could shed some light on this issue. Thanks. UPDATE EDIT: The desktop.ini file in the folder containing Chrysanthemum.jpg contains the following entries. The .dll files used to translate the various resources are unfortunately not human-readable and I have no clue as to how they could be generated for other files created by the user to be translated, but they serve the purpose, and solve the mystery which lead to the post. Thanks. [LocalizedFileNames] Chrysanthemum.jpg=@%systemroot%\system32\SampleRes.dll,-101 Desert.jpg=@%systemroot%\system32\SampleRes.dll,-102 Hydrangeas.jpg=@%systemroot%\system32\SampleRes.dll,-103 Jellyfish.jpg=@%systemroot%\system32\SampleRes.dll,-104 Koala.jpg=@%systemroot%\system32\SampleRes.dll,-105 Tulips.jpg=@%systemroot%\system32\SampleRes.dll,-106 Lighthouse.jpg=@%systemroot%\system32\SampleRes.dll,-107 Penguins.jpg=@%systemroot%\system32\SampleRes.dll,-108 [.ShellClassInfo] LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21805

• How can I add a second hard drive to a previously configured UEFI/ACHI Windows 8 machine?

  - by pflyer

  Recently purchased a new Windows 8 PC. It came with one hard drive. I want to a second hard drive to it. This second hard drive is my data hard drive from my previous computer. However, I have run into issues when the system accesses it. The drive is found in the BIOS. But is not seen by Explorer or Disk Management. I have added the drive to the next available SATA slot: SATA 2. The machine is a UEFI/ACHI based machine. In my reading I have found people documenting the following: 1) adding multiple partitioned hard drives (like mine is) to UEFI based machines is not possible 2) I have seen it suggested that you can only add blank hard drives to UEFI based machines. However, in doing so, I did not have success. I tried to add it as a hard drive with unallocated space and then as a hard drive with a single simple partition. Both attempts failed. My ultimate question: What is the proper procedure for adding a second hard drive to a UEFI/ACHI machine? I do not want to reinstall the OS and start from scratch as I have seen suggested elsewhere. There has to be a way to accomplish this without all that hassle. Thanks in advance for your help.

• 2 Printers 1 Queue

  - by Shazburg

  My issue: When an order is processed, the same document needs to be printed on two printers. My proposed solution: Create a single queue in CUPS with a backend script that spits the job out to the two real printers queues. My problem: Documentation. Maybe I'm looking at every ring around the bullseye, but I can't find anything that lays out the rules for writing a CUPS backend script. In the end, I have several questions: Is there already an option to do this in CUPS that I've missed? The line I use to add my queue is "lpadmin -p MultiPass -E -v multipass -P Generic PostScript Printer". But DeviceURI is bad unless I specify a directory like "-v multipass:/tmp". Why is this? For testing, my script does nothing but capture ARGV and write it out to a text file one line per argument. Problem is, I'm getting nothing. Logs show the job as successful, but I'm pretty sure my meager attempt at a backend isn't even being run. I've tried to keep this question brief, so please ask for more info as I'm sure I've left out the most important part in all this. Honestly, I'm just done chasing my own tail. Thank you for your time.

• Set up Linux box as WAP for MyBookLive?

  - by AcidFlask

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

• Wake for Network Access Apache servr in OS X 10.8, followup

  - by Gary

  Sorry, I can't seem to post this response within the same thread. Thank you both (Zoredache and Gordon) for your answer. But the fix seems temporary. I entered the command you suggested, and it seemed to work: ...smith$ Registering Service ApacheNoDoz._http._tcp.local port 80 DATE: ---Fri 14 Sep 2012--- 12:04:15.813 ...STARTING... 12:04:16.566 Got a reply for service ApacheNoDoz._http._tcp.local.: Name now registered and active So, I checked for it on my G5: Browsing for _http._tcp Timestamp.....A/R Flags if Domain......Service Type...Instance Name (lots of Bonjour printers omitted)... 12:07:38.370..Add.....2..4 local.......... _http._tcp.........ApacheNoDoz 12:07:45.921..Rmv.....0..4 local..........._http._tcp.........ApacheNoDoz So, it was running at 12:07:38, at which time the host was asleep. But, shortly after, the activity seems to have been removed. I don't know why. Does this mean that I can never let the cpu sleep, or is there something else I have to set? Thanks, again.

• Windows 8.1 Update 1 Disk Usage 100%

  - by Gookjin Jeong

  Background Information / Computer Specs I have a 14-inch Samsung Series 5 Ultra. Core i5 CPU, 750GB HDD, 8GB RAM, Intel HD Graphics 4000. I've had the computer for about 1.5 years with no major problems. Problem The issue appeared at the beginning of April this year, when I updated the OS to Windows 8.1 Update 1 (not from 8 to 8.1). After being on continually (except for at night, when I put it on sleep mode) for about 48 hours, the disk usage as seen by Task Manager hits 100%. When this happens, everything from opening/closing applications to typing and even bringing up the start screen by pressing the Windows key becomes extremely slow. The only way to make the disk usage decrease is to restart the computer. Then the problem repeats. I've used my current laptop (as well as my previous laptops) this way -- putting it on sleep mode at night and restarting it only when Windows needs to install updates -- for a long time. So I know the 100% disk usage is not due to the way I use the computer. The thing that causes the spike varies. Sometimes it's System, sometimes it's one of the various applications I installed (e.g. Chrome, Evernote, Spotify, Wunderlist, iTunes, etc.), and sometimes it's Antimalware Service Executable, etc. Tried Solutions I think I tried almost every solution out there for this problem: Running the check disk command (chkdsk /b /f /v /scan c:) from Admin Command Prompt Running Windows Memory Diagnostic Disabling Superfetch and Windows Search from services.msc Running "Fix problems with Windows Update" from Control Panel -- Troubleshooting Updating and rolling back the graphics driver (Intel HD 4000) Disabling "Use hardware acceleration when available" from Chrome settings Disabling Intel Rapid Storage Technology Running the SFC /SCANNOW command as recommended here Running a quick scan & a full scan from Windows Defender (no threats found) Taking the hard drive out and putting it back Refreshing the computer, from the Update and recovery -- Recovery option in Windows settings NONE of the above worked for me. I was about to give up but then noticed that one of the main culprits of the disk usage spike, as shown in the "Disk Activity" section of the Resource Monitor, was C:\System (pagefile.sys). I googled around and found that one of the recommended solutions was to disable pagefile. I then went to **Control Panel -- System and Security -- System -- Advanced system settings -- Advanced tab -- Performance settings -- Advanced tab -- "Change" under Virtual memory and discovered that the number for "Currently allocated" at the bottom was 1280MB, although the number for "Recommended" was 4533MB. I immediately changed it to 4533MB and checked my family members' computers to see what the numbers were like. All of theirs had a currently allocated space that was only slightly smaller than the recommended space. See screenshot below: This might fix the problem. I'll have to wait a couple more days.But if it doesn't, what in the world should I do next? I'm guessing the hard drive isn't failing because This computer is less than 2 years old; and Speccy says that the status of the HDD is good. Update 5/27/2014 The "4533MB" solution did not work. I had to reboot the computer about 30 minutes ago because the disk usage again hit 100%. When I opened Resource Monitor the C:\System (pagefile.sys) again was shown to be the culprit. I have now disabled pagefile entirely via the same window shown above in the screenshot. The number for "currently allocated" is now 0MB. Will update again in a couple days, or if the problem occurs again, whichever comes sooner.

• How do I Forward root's email to an external email address?

  - by ErebusBat

  I have a small server (Ubuntu 10.04) at my house and I would like to forward root's email to my gmail hosted domain to get security notifications and what not. I ripped everything out and started from scratch and ran into some other issues. I now have sendmail working in the sense that I can mail [email protected] and get the mail. HOWEVER, adding an address to /root/.forward does not actually forward the message. I get the following in my logs: Dec 22 14:04:37 batcave sendmail[4695]: oBML4bAT004695: to=<root@batcave>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30075, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBML4bJ9004696 Message accepted for delivery) Dec 22 14:04:39 batcave sm-mta[4698]: STARTTLS=client, relay=[69.145.248.18], version=TLSv1/SSLv3, verify=FAIL, cipher=DES-CBC3-SHA, bits=168/168 Dec 22 14:04:40 batcave sm-mta[4698]: oBML4bJ9004696: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:00:03, xdelay=00:00:03, mailer=relay, pri=120336, relay=[69.145.248.18] [69.145.248.18], dsn=2.0.0, stat=Sent (OK 01/D4-00853-216621D4) You can see where my local sendmail instance accepts it then hands it off to my ISP, but with the wrong address ([email protected]).

• How to keep subtree removal (`rm -rf`) from starving other processes for Disk I/O?

  - by David Eyk

  We have a very large (multi-GB) Nginx cache directory for a busy site, which we occasionally need to clear all at once. I've solved this in the past by moving the cache folder to a new path, making a new cache folder at the old path, and then rm -rfing the old cache folder. Lately, however, when I need to clear the cache on a busy morning, the I/O from rm -rf is starving my server processes of disk access, as both Nginx and the server it fronts for are read-intensive. I can watch the load average climb while the CPUs sit idle and rm -rf takes 98-99% of Disk IO in iotop. I've tried ionice -c 3 when invoking rm, but it seems to have no appreciable effect on the observed behavior. Is there any way to tame rm -rf to share the disk more? Do I need to use a different technique that will take its cues from ionice? Update: The filesystem in question is an AWS EC2 instance store (the primary disk is EBS). The /etc/fstab entry looks like this: /dev/xvdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2

• What is the oldest hardware still in production use? How is it kept running?

  - by sleske

  In the spirit of the question What is your oldest hardware that still works?, I'd like to ask: What is the oldest hardware you know that is still in production use? And what challenges did you (or someone else) face in keeping it running (scarce documentation, no support, no spare parts available...)? Most organizations will retire / upgrade software and hardware after 5-10 years, but sometimes old software is kept running on old boxes, because it "just works". I once worked at a client site that was running a critical piece of (in-house developed) business software on a single server running HP-UX. The server was old (ca. 12-13 years), but fortunately still running without problems; however, getting spares would have been very difficult, and since software installation was undocumented, any significant system changes or even new hardware might have caused significant downtime and data loss. We eventually managed to replace it, but this is not always possible. I also read that many organizations still run decade-old mainframe hardware, particularly for highly customized systems controlling industrial machines or power plants. Which old hardware have you encountered? How did you manage these challenges? Related question: http://serverfault.com/questions/82467/should-old-servers-be-retired

• Why are my Windows 7 updates continuously failing?

  - by Chris C.

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

• Which CPU for XEN - LAMP testbed - Budget

  - by deploymonkey

  Dear serverfault knowledgeables, im in a decision dilemma right now, which I can't resolve due to lack of hands on experience. I need to build a testbed for basically virtualizing a LAMP application (os'ses not yet decided) including server side calculations. I'll opt for XEN since it seems better supported by cloud hosters at the moment. The hardware is for a proof of concept for a startup doing saas and might be used for closed live alpha/beta later on. After testing, the testbed might be a) deployed as a colocated white box server b) used as workstation Single socket is enough. We want to have ECC memory for reliability, this excludes most of the consumer line at intel. If intel CPU, then threaded cpu (HT) is preferred have at least 16 gig ram If justified by price and reliability is not too bad, a high quality desktop MB instead of a server MB would be worth a try It came down to the opteron 6128 vs. the xeon 5620 for me after a lot of research, but I don't necessarily have to be right. Which CPU is preferrable, concerning TCO (MB price, power requirements 24/7...) , Opteron 6128 or Xeon 5620? Which one offers better performance in real world applications? (Do You have any other suggestions I probably overlooked?) Thank You for Your consideration

• Transcoding media server streaming to the iPhone

  - by pilif

  I have a huge collection of videos in different formats, but with one thing in common: They are not playable on an iPhone (or iPod Touch). Instead of complaining about Apple's IMHO broken world view ("there are no video formats but quicktime and mp4"), I wonder if there's a solution out there that allows streaming these different videos to the iPhone. This means that the source media needs to be transcoded on the fly. I already tried a few solutions out there, but with varying success: PS3 Media Server kind of worked, but only once and only for one single file. TVersity is said to work, but it requires UAC to be disabled and I don't see any need for this. The solution I'm looking for should run on Windows 2008 Server or Linux. I just can't believe that there's nothing out there that would allow me to stream my huge video collection on my iPhone (we're talking Wifi here, not 3G). After looking at the answers provided and after retrying TVersity without much success, I gave Orb another try and while the web interface failed to work for me, the iPhone Application (I tried the free one at first) actually worked flawlessly. And not only that, it also manages to convert the streams on-the-fly, so you don't have to wait for the transcoding process to finish before playback starts. On my 2.26 Ghz MacMini Server, this worked even with 1080p material. For Windows 2008 Server users out there: Remember to install the Desktop Experience Feature in the Server Manager if you intend this to work. Of all the stuff I had a look at, this really provided instant-success - even though I'm now probably sending the contents of my harddrive to orb's central server (sigh)

• Wifi antenna extension with F-connector/RG-6(RG-59) cable?

  - by rjz2000

  In an older house, the wire mesh in walls surrounding the furnace behave like a Faraday cage and block wifi signals. It is also difficult to lay new cable, however there is television cable to multiple locations due to there once having been a roof-installed, television antenna. It would be relatively trivial to install the wifi router at the center distribution point, then have the antenna broadcasting/receiving the signal plugged in at each of the old television outlets. I assume that it would not be too difficult to find an adapter for SMA <- F-type connectors. The cable is actually RG-59 rather than RG-6, but I assume that it still has relatively good RF isolation along its length, which is no more than a couple hundred feet in any direction. Does anyone know a problem with the idea? Will a router get confused if there is /too little/ interference between the two antenna? Is that length of cable (~100ft) too long for the signal a router broadcasts? I have seen that it is also possible to use old ~$30/each FiOS cable modems available on eBay to extend a network over television cable. However, that seems like a less elegant solution, and might interfere with upnp and dlna services I'd like to have work on a single network. Thanks if anyone has answers or suggestions before I try this project!
