• Advice for UPC/Surge Protector in home office

  - by user37755

  I'm just starting out as an independant developer, mostly Unix stuff with some Windows thrown in occasionally. I've been running two machines, a linux and a windows dev machine. Long story short, we had a bad storm come through last week and I unplugged one machine, forgot to unplug the other and the p/s and mobo ended up dead. Luckily I backup to an external service religiously (rsync.net for anyone interested), so there was no loss in data, but it did show me a glaring hole in my current setup, namely, lack of UPC and Surge Protection (this has honestly never been an issue before). Can anyone recommend a UPC/Surge Protector for a home office? It only needs to support a single machine (I opted to use vmware instead of rebuilding that machine), but it's a quad core Phenom 2 with a 1k watt p/s. This is outside my experience so I thought I'd get some input from others. I'm looking for something that's reasonably priced and does the job reasonably well. I don't need absolute 100% uptime, just something to protect my PC better than it is now.

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Sizing Switches for Storage and Production

  - by Untalented

  Couple questions. Should you always completely separate the storage network switches from production switches or are VLANs fine to segment this traffic? Is there a golden rule here? How do you properly size a switch for your environment based on the specifications the manufacturer provide (Throughput, Forwarding Throughput, Stacking Throughput, Max Mac)? If you have two switch options and one has a maximum Mac address of 8,000 vs. another with 16,0000. What does this really mean to me? How do make sure one vs. another is sized properly for me? Besides VLAN and Jumbo Frame support, is there any other "Must" haves for a virtual environments production or storage networks? There is a wealth of knowledge on sizing SANs and such, but this seems equally important and it's quite challenging to find as much information. -- Just to add some tidbits of information for the environment. This setup above is referring to the data centers which supports two different locations which have about 100 users between the two in total. The storage traffic will be iSCSI and will be 3 ESXi Hosts and one SAN housing about 2.7TB of data. Since there is currently no storage network in place (no SAN), I'm having a hard time regarding #2 to really determine what backplane throughput and switch specifications will be sufficient.

• How do I find and kill a php loop (process)?

  - by Hoytman

  I have a php script that I have been developing which calls an external api within a loop. It is being tested on a VPS which is running LAMP on Debian. I noticed this morning that the api was not responding to my script. When I called the provider, they told me that my server had been calling the api 1000's of times per hour for the past 10 hours. I am assuming that a php script (which I have been working on the day before and testing on my VPS) entered into an infinite loop during one of the executions, and never came out (I have been testing it from the command prompt, and not over the web.) I have attempted to stop and start Apache, but the api support staff says that the calls are still coming in from my server address. How can I find and stop the process? Also, is there a possibility that the Apache stop/start solved the problem, but the api is still trying to sort through past calls? Please forgive me for not using my local test environment correctly. Edit: I do not know the process name, I need to discover the name (or pid) based on behavior.

• Out of memory errors but not actually out of memory...

  - by commradepolski

  So, myself and my fellow support techs have been fighting with this issue and we still dont know what the problem is. Lets start off with the system specs: Windows XP 32 bit Corporate (SP2 and SP3) Intel D975XBX2 Mobo 4gb of ram Intel Core 2 Quad Q6600 ATI Radeon HD 3600 - 512mb After a few hours of working on the machine, the end user will begin to see the following symptoms: Out of memory messages Title bars and menus dont draw in properly Problems accessing network resources Problems opening up documents such as MSWord and MSPowerpoint and text files Problems opening up explorer windows General instability We have looked at task manager while this issue was occurring, and all indicators, like PF usage, threads, handles, etc. are normal. We have been having trouble pinpointing the root cause of this issue. It is also not situated with one user, it affects 8-10. So far we have tried: Resetting CMOS (Waiting to see results) Replacing video card (didnt help) Windows updates (didnt help) Updating network drivers (didnt help) Switching user from 1gbps to 100mbps network connection (awaiting results) Swapping the affected user's hardware (waiting for results) Increasing desktop heap size (helped for a bit but then the issue became more frequent) Applying the /3 switch to XP (didnt help) Increasing and decreasing and setting PF to system managed state (didnt help) We did have a power outage at the office a couple weeks ago, and all these issues became more frequent. Prior to the power outage it may take a week or so for the users to experience the issues but since the power outage it takes 3-4 hours or less. We havent had reports of the above issues causing BSODs, although that would be easier to diagnose :). Any help is greatly appreciated.

• query keepalived

  - by tdimmig

  *Note: I have trouble deciding what should go in serverfault and what should go in superuser, if some kindly admin decides this is in the wrong place please move it for me - many thanks. I am implementing a basic HA system with keepalived. I only want to be notified of the failover in the case of hardware failure. I do, however, have the servers switch roles periodically. I have a track_script running on the backup that will vary it's return between 0 and 1 on an interval (once a week, once a month, whatever). Upon returning 0, the priority is raised above that of the master, upon returning 1 the priority is lowered again. This way they trade places on the configured interval. The question: What can I do to tell the difference between a switch caused by my script, and a switch caused because one of the servers died? I certainly want to be notified when there is an actual problem, but not every time the servers change places because of the script. I see that version 1.2.7 has snmp support and I may be able to use it to get some information that could tell me one way or another, but to be honest I've never used snmp before and I don't know how to get the information I want with it (my Google foo failed me).

• Is it logical that file system acls would be corrupted in a way that adds permission for another user?

  - by wilbbe01

  I was having issues on a shared hosting provider with the host's web server instance not serving some files. I asked the companies support about the issue and they responded with the results of getfacl on my home directory, and added the necessary line to allow their web server to obtain the necessary permissions. All is working happily now, but I noticed a line in the getfacl that was for what appeared to be another username to which I had no relation. I asked them about this and their response was that it was likely some minor corruption and that I could remove the unwanted line with the setfacl -x option. I know I never added the user to my home directory, and I also find it weird that that could truly happen due to corruption. So now that it is fixed I'm a little bit weary of whether or not they were trying to cover up a problem they accidentally gave someone permissions to my account, or if this kind of thing can really be corrupted in that way. Especially when that user is a real user on the same server. Any thoughts? Thanks.

• Removed Old Domain Trust. Now Progress (9.1D) can't open DB File

  - by RLH

  My company has an old server, running Progress 9.1D on a Windows 2000 VM, which was used by our company OS (Vantage 6 by Epicor.) Vantage was our primary OS for a very long time. About 2 years ago, we migrated to a larger, corporate OS and we cancelled our service contract with Epicor. Yesterday, we removed an AD trust between the corporate domain and our old AD domain we used in the days of Vantage. After restarting the virtual server, I have been able to start the ProService for 9.1D Windows service, however, I can not get Vantage to start back up. When I run the application, I get the error in the message listed below. Transcript: ** Could not connect to server for database [progress db file], errno 0. (1432) How can I fix this? FYI, I haven't had to work with Progress in years and even then I wouldn't have considered myself a "novice"-- I'm even less knowledgeable than that title would suggest. Vantage had a lot of internal tools and I recall that Epicor support managed to prevent .pf scripts from being executed. If there was a Progress specific patch that needed to be applied, you had to do it within the Vantage software OR they had to remote into the machine to fix this. I may not be able to run a .pf script but I do know that I can log into the console-based server application. (Yes, I can't even recall which utility that was called. It is sad.) It's been a long time and I never had to digg into Progress that much. Please help and feel free to ask questions. If you need more info, I'll update this post.

• What are the advantages of registered memory?

  - by odd parity

  I'm browsing for a few low-end servers for a startup and I'm a bit confused about the different memory types. The advantage of ECC is clear - single-bit error correction. When it comes to registered memory it seems more vague, especially in systems that support both registered and unbuffered memory. A Google search mostly finds copies of the Wikipedia article, which states that registered memory chips "...place less electrical load on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise". However I can't find any quantification of this. What I'm wondering about is: Is registered memory an improvement over unbuffered when it comes to soft error rate, or is it purely about the maximum number of modules supported? If yes, at what point (amount of modules or GB of memory) do these improvements start to become noticeable? For a specific example, the HP ProLiant DL 120 G6 server manual states that maximum supported memory configuration is 16 GB unbuffered (4x4GB) or 12 GB registered (6x2GB). In this case I'd rather have the extra 4GB of memory if the reliability difference is negligible.

• How do I serve Ruby on Rails applications on Windows Server 2008?

  - by Adam Lassek

  I have spent the last several hours attempting to get Ruby on Rails running on a Windows server with no luck. At first I tried configuring a test application through IIS7's FastCGI support, but the documentation for this is not very good. I've been following this blog entry, and this one, and this one, and this one but everything seems to be missing major steps, or are out of date. And every article keeps linking back to this Howto from rubyonrails.org that doesn't exist. The sense that I'm getting is that even if I manage to make this work, IIS' FastCGI isn't good enough to use in a production environment anyway. So it looks like my best bet is to setup a reverse proxy in IIS that points to Apache & Mongrel/Passenger using ARR and UrlRewrite. Is there anybody else out there stuck deploying a Rails application on a Windows stack? Am I on the right track? Can you give me a better idea of how to configure this? I believe Plesk already installed an instance of Apache/Tomcat running on this server using a different port, so adding another virtual host shouldn't be difficult; the hardest part seems to be setting up the reverse proxy through IIS.

• Windows 7 does not detect my new hard drive?

  - by jasondavis

  I just built a really nice new PC. Some specs... Intel i7-930 CPU ASRock Extreme X58 motherboard with sata 3 and USB 3.0 12gb of G-Skill DDR3 RAM 80gb Intel G2 Solid state drive for Windows 7 and other programs to run on Windows 7 Pro 64bit OS 2 1gb grapghic cards for 4 monitor support Thats the main components. Well today my new 1tb western digital hard drive came which I plan to use for data to preserve the life of my SSD (hopefully). I hooked up it's sata power input and then hooked up it's sata data cable to a sata 2 port on my motherboard, I boot windows 7 and go into my computer and the drive is not showing up with my other drives. I then re-boot again and check again, no luck. I then shut down the PC and open the case back up, I then check my connections and they all look good. I then boot up and I can see the new HD is on and spinning. I then go into my BIOS settings to see if it registers there and it DOES! It shows I have a WD 1tb hard drvie on sata 2 port 6. So I am at a loss of why it is not showing up as an option in windows? Windows acts as if the drive is not there. Please help

• PHP 5.3.5 Windows installer missing php_ldap.dll

  - by nmjk

  I'm working with Windows Server 2008, Apache 2.2. I'm using php-5.3.5-Win32-VC6-x86.msi as the installer, using the threadsafe version. I've gone through the install process four or five times just to make sure that I'm not missing anything ridiculous, but I don't think I am. The problem is that the php_ldap.dll extension simply doesn't seem to exist. It's not present in the installer interface (where the user is asked to choose which extensions to install), and it definitely doesn't appear in the ext/ directory after install. I found a lot of mentions of this issue for 5.3.3, including links to download the extension individually. Those links no longer exist, of course, and besides: they were for 5.3.3. I'd really rather use an extension that belongs with PHP 5.3.5. Anyone else encounter this problem? Any ideas as to what's going wrong? Anyone seen acknowledgement by the PHP folks that the file is indeed missing, and that it's an oversight? It's quite a frustration because the server I'm building has no purpose if I don't have PHP LDAP support. Cheers all, and thanks in advance for your assistance.

• How do I back up Hyper-V VMs with Windows Server backup on Windows Server 2008 R2?

  - by Chris

  I've searched this site and google, and I CAN find information about how to back up Hyper-V virtual machines by using Windows Server Backup from the Hyper-V host in Windows Server 2008. You have to set up a registry key to enable the Hyper-V VSS writer, and then you can take online backups of your VMs. However, all the information I have found is about a year old, and none of it has been updated for Windows Server 2008 R2. I tried to run the "FixIt" .msi found here: http://support.microsoft.com/kb/958662 ... but it said that it was not applicable to my operating system. So I am thinking either Windows Server 2008 R2 already has its VSS service for Hyper-V enabled, or it still needs to be enabled but the FixIt package doesn't feel comfortable operating on an OS that wasn't RTM at the time. I went ahead and scheduled a windows server backup for 9pm tomorrow. It said it would take 86 GB, which means it MUST be counting those VMs. But will this backup fail? Can anyone confirm whether you have to apply the same registry changes for R2?

• Determining how all memory is used in Windows Server 2008

  - by Mojah

  Hi, I have a Windows Server 2008 system, which has 12GB of RAM. If I list all processes in the Task Manager, and SUM() the memory of each process (Working Set, Memory (Private Working Set), Commit Size, ...), I never reach more than 4-5GB that should be "in use". However, task manager reports this server has 11GB in use via the "Performance" tab. I'm failing in determining where all that used RAM is going. It doesn't seem to be system cache, but I can not be sure. It might be a memory leak in one of the appliances, but I'm struggling to find out which one. The server's memory keeps filing up, and eventually forces us to reboot the device to clear it. I've been reading up on how RAM assignments work on Windows Server: RAM, Virtual Memory, Pagefile and all that stuff: http://support.microsoft.com/kb/2267427 What's the best way to measure? http://www.zdnet.com/blog/bott/windows-7-memory-usage-whats-the-best-way-to-measure/1786 Configure the file system cache in Windows: http://smallvoid.com/article/winnt-system-cache.html But I fear I'm stuck without ideas at the moment.

• Screen recording in Windows 8 makes PC unusable?

  - by Skadier

  OS used: Windows 8 Pro x64 Hi there, I got a weird problem. I tried to record my screen using different screen recording applications like Camtasia7, Hypercam, and some others. So if I hit "record" everything works fine for about 3-4 seconds. Then the PC slows down heavily caused by extremly high IO usage. The PC gets nearly unusable and laggs like hell. I can't switch applications, can't get TaskManager with Ctrl+Alt+Del, or something else without waiting 1-3 Minutes. After about 5-8 Minutes and a bit of luck I am sometimes able to end the process of the recorder and IO calms down very slow(100% IO lasts for about 2 Minutes before becoming normal). I don't know why this happens. Screen recorders that support Windows 8 aren't out afaik but at least Camtasia7 worked with Windows 8 Developer Preview and Windows 8 Release Preview (only had to change record method to .avi). No slow downs or something else. Is there anyone out there who knows this problem too? Is there maybe a solution to this problem?

• HSphere - Only sees Apache 2 Test Page after forced shutdown?

  - by Darkwoof

  Hi, I have a dedicated server running on a Dell PowerEdge 850 with CentOS 4.4 and HSphere 3.0 Patch 6 colocated at a datacenter. Last night my hosting company had to schedule a change in the power bar, and I gave the go ahead for them to shut down the server and bring it up when they are done. Since they do not have admin access to the machine, I suppose they did a forced shutdown. When the machine was brought up, I found that all my domains (and sub-domains) are now pointing to an "Apache 2 Test Page" instead of the pre-configured sites that were running prior to the shutdown. This apparently only affects the standard sites running on port 80 - my Webmin instance running at port 1000 is still accessible for example, as well as my HSphere control panel running at port 8080. I've checked the config settings using the HSphere UI for each of the sites, and didn't find anything wrong. I've also tried rebooting the server via SSH, which does not rectify the problem. I've previously done reboots with no issues; the sites would just come right back up when its done, but not this time. I'm guessing some configuration file got corrupted or overwritten this time? Anyone with experience with HSphere and can provide some advice on what's happened and how to solve it? Thanks. (I do not have an active support agreeement for HSphere since Parallels took over and increased the min. license to 200. I only had 25 license for use by family and friends.) Thanks in advance.

• Profile not loaded correctly (Cannot access registry)

  - by xaav

  Every so often, I log on and get the Following Message: User profile was not loaded correctly. You have been logged on with a temporary profile. Changes you make to this profile will be lost when you log off. Please see the event log for details or contact your administrator This almost always happens when somebody else has been on the computer for a while, and then I log on. This never used to happen, but now it happens pretty often. My profile is not permanently corrupted, all I have to do is restart my computer, but this annoys me, and I would like to fix it. I was curios about the reason of this cause, so I looked into the Event Log, and found the root of the problem was the ntuser.dat file in the profile that I was logging on to was locked at logon time. This resulted in the current users registry not being loaded, resulting in failure to load the profile. I just found a microsoft article that mentions this exact issue: http://support.microsoft.com/kb/960464/ The problem is that I do not want to delete this profile; and this issue does not come up every time that I log on, only when somebody else has been on a long time before me. What could be locking this file? Is there any way to get a process list without logging on so that I can identify which process has the file locked? Any other suggestions?

• Fedora Core 6 Migration

  - by Matthew Sprankle

  I am at a loss as to what I should to for this server. I need it to run php5.3 and corresponding version of mysql. I received a client today through work that is using Fedora core 6 running 10 very small websites on some very hodge podge setup. My original idea was just upgrade to php5.3. I have yum (installed 3.0.8) reconfigured for the fedora archive. The latest version of php it allows is 5.1.8. I am still relatively new to server setups and am nervous about wiping their server to upgrade it. Since it is about 6-8 years old I'm not sure if it will even support the newest version of fedora. The server specs are: Parallels Plesk Panel version 9.5.4 Operating system Linux 2.6.9-023stab048.4-smp CPU GenuineIntel, Intel(R) Xeon(R)CPU E5335 @ 2.00GHz (10gb disk space and 1gb of memory). I use fedora for my personal server so I was a little familiar with it. I haven't done anything too extravagant. Is there a way I can escape this nightmare with installing php5.3 or do I need to migrate these sites to a new server?

• HP LaserJet 1515: Disable "refill" warning

  - by Pekka

  I have a HP LaserJet 1515 connected to a Windows 7 PC. The Magenta cartridge is empty; the printer shows a warning to that effect, and won't let me print even black-and-white documents any more. I can't turn the warning off manually using the printer's small console: When I try to enter any menu, the display says "Menu access disabled". I have no idea why. There is a setting to override the warning, but it can't be changed using the Network interface in the browser (Although it is there on the status page) According to the manual,the HP printing tool is supposed to offer a switch for this, but it won't install on my Windows 7. It just rumbles about for half an hour, to magnificently exit with an "unknown error" requiring a reboot. On second look, the problem seems to be that Windows 7 just isn't supported. There is no download link for the tool when you specify Windows 7 as your OS. I just want to print a black-and-white-document on a printer whose black cartridge is still 65% full. Is this indeed impossible? On second thought, I'm cross-posting this on the HP support forum. I'll update here if anything comes up.

• Partitioning of Ubuntu server which will use OpenVZ and encrypted partitions (unlocked through SSH l

  - by DeletedAccount

  Hi, I'm about to install a server. Some context: My HDD is 1 TB and I have 2 GB RAM Ubuntu Server Lucid Lynx AMD 64 I will use OpenVZ and have most functionality separated into containers. To support disk quotas I need to use ext3 (not ext4) for the container partition. Each time I reboot the server I want to be forced to login through SSH and mount the encrypted partitions by typing my password (if someone steals the server, no critical data should be available). I want to have as much as possible encrypted. Yet I want to be able to login through SSH as I don't have a monitor or keyboard at the server. I am not sure how big I need my partitions to be. Being able to resize them later would be nice. I guess it implies using LVM? But the manual partition mount using SSH is also very important (in fact it's more important, if I have to pick one). How do you recommend that I partition the HDD? If I have daemons which needs the encrypted partitions, will they fail and can I just restart them after mounting the needed partitions?

• Can my employer force me to backup my personal machine? [closed]

  - by Eric B

  Here's the background: Approximately 1.25 years ago, the company I work for was acquired by a larger 400 person company. Before acquisition (and today still) we are all remote employees using our own personal hardware for work-related duties (coding, email, etc). We are approximately 15 employees within the larger organization. Some time after acquisition, the now owning company was slapped with a civil lawsuit. Part of this lawsuit (discovery) is requiring them to retrieve & store from us any related information. Because we were a separate company up until acquisition, there is a high probability that our personal machines might contain information about what the lawsuit alleges (email, documents, chat logs?, etc). Obviously, this depends largely on the person's job function (engineer vs. customer support vs. CEO). All employees are being required to comply. Since acquisition (1.25 yrs), the new company has not provided us with company laptops/desktops. We continue to use personal hardware, licenses, etc for work. Email is via POP3s and not hanging around on the mail server - it's on everyone's client. Documents are spread across personal machines. So, now they want us each to backup our complete personal machines. They are allowing us to create a "personal" folder where we can place personal documents. That single folder will be excluded from backup. Of course, that means total re-arrangement of documents, etc. For most of us, 99% of the data on the machine is NOT related to work. So, what's the consensus? Should we comply? What is their recourse if we do not?

• Windows 7 host with Ubuntu Guest and a performance hit, memory locks?

  - by Cyrylski

  I have a brand new Lenovo T510 with Core i5 and 4GB of RAM with Windows 7 on it. I Installed Ubuntu 10.10 in a Virtualbox. For some reason system gets really slow on this setup which makes me really angry. There's a video card shared with full 3D support enabled and 1GB of RAM allocated for the Ubuntu machine. It may sound stupid, but WHY is the whole memory consumed in an instant when I run Virtualbox? I struggled for like 10 minutes restraining myself from a brutal reset, and now everything runs smooth but memory "in use" in Resource Monitor is 3GB flat with only Chrome running. I'm new to Windows 7, but I'm really disappointed with performance at this point... I used to work in a different environment with much slower hardware and there was no such problem (WinXP over Ubuntu, 1GB out of 2GB allocated for WinXP guest on intel GMA). This is, until I clogged RAM totally there. But I was capable of running Chrome, Firefox and Apache server on a 1GB RAM in Ubuntu there and Photoshop CS4 on Windows XP and it worked. In this case I can't go beyond setting up Ubuntu properly. I bet I'm doing something wrong.

• How many iptables block rules is too many

  - by mhost

  We have a server with a Quad-Core AMD Opteron Processor 2378. It acts as our firewall for several servers. I've been asked to block all IPs from China. In a separate network, we have some small VPS machines (256MB and 512MB). I've been asked to block china on those VPS's as well. I've looked online and found lists which requires 4500 block rules. My question is will putting in all 4500 rules be a problem? I know iptables can handle far more rules than that, what I am concerned about is since these are blocks that I don't want to have access to any port, I need to put these rules before any allow. This means all legitimate traffic needs to be compared to all those rules before getting through. Will the traffic be noticeably slower after implementing this? Will those small VPS's be able to handle processing that many rules for every new packet (I'll put an established allow before the blocks)? My question is not How many rules can iptables support?, its about the effect that these rules will have on load and speed. Thanks.

• Windows 7 permissions and Samba domain

  I'm the main desktop support in an office of mixed MacOS and WinXp machines, about 60. I'm new to Windows 7. Currently our XP users are admins on their own machines, and my boss is wanting us to get away from that now that we're going to Windows 7 (64bit). My boss is largely absent from my day-to-day work, so I'm here looking for help =) I have numerous unattended .cmd scripts that we run from a server share, unattended software installs. Some run at login, some have to be run manually. With the NetworkAdmin account logged on to the computer, I am able to run the .cmd files and install stuff just fine. With my test account logged on (Power User), I cannot run the .cmd file - I get an Access Denied. When I change my test account to an Admin on the machine, I still get access denied. However, the test account can simply double-click the .exe and install the software just fine, as admin. Power User can't install anything. How do I fix it so that any power user or admin on the machine can run anything as long as it's on our shared software drive?
