  • How to increase acpiphp slots?

    - by Eil
    Oh RHEL 5.5, there are 31 ACPI PCI hotplug slots by default: acpiphp: Slot [1] registered ... acpiphp: Slot [31] registered Is there a way to increase this number? I haven't been able to find an argument to supply to modprobe, or a sysctl knob to tweak, but I know there must be ways to get more slots based on some Google sleuthing. (For the curious, this is just preliminary experimentation to see how many virtual disks I can hot-add to a running KVM guest.)

  • Windows 8 "Upgrade Offer" eligibilty when running the Consumer Preview in a VM?

    - by Dan Harris
    If I have a VM running Windows 8 Consumer/Release Preview, am I allowed to take advantage of the Windows 8 upgrade offer, and install it on that machine? I would have assumed not...as there was never a licensed version of XP SP3 through to Windows 7 installed in that VM. It was a clean installation of the Consumer Preview into a VM. My confusion comes from the notes at the bottom of the download page for the Upgrade offer which states: Offer valid from October 26, 2012 until January 31, 2013 and is for individuals and small businesses needing to upgrade up to five devices. If you are a business customer looking to upgrade more than five devices to Windows 8 Pro, contact your Microsoft partner for more information. To install Windows 8 Pro, customers must be running Windows XP SP3, Windows Vista, Windows 7, Windows 8 Consumer Preview, or Windows 8 Release Preview. I am assuming it's not possible and i'll need to purchase the System Builder edition to install within a VM? My guess is that you can use your downloaded upgrade offer only if you updated Windows 7 to the release preview, and therefore had the Windows 7 license on the machine, I used the serial number from the Microsoft Website when downloading the Release Preview, and did a clean install, so there was never a Windows 7 license on the VM. I have MSDN for development purposes, but I am looking to run in a VM for personal use as well, so my MSDN license is not valid for that particular use.

  • 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.

  • How to setup bindings for development IIS 7.5 with lot of sites

    - by Antonio Bakula
    I am a programmer in a small ASP.NET shop with very little expirience in server administration, and I have to setup IIS 7.5 to host lot of sites on newly installed windows server 2008 R2, these sites are test "clones" for sites on "real" web server and they should be accessible only in local network (domain). Developers should add new sites for our new customers. Project managers use this server to check progress and test new sites and new features, QA people have to have access to this site and test before we copy it to the "real" web server. Developers only have access to IIS console, in fact they can use RDP to test server with their developer domain credentials and permissions, also developers are local admins on that machine (tester). On our previous server I used different port numbers for each site. That worked but don't like this solution, I would prefer to use subdomains. But here are the problems: manually adding DNS records is not an option because we do not wont that developers have to administer domain DNS server, and currently this had to be done with domain administrator credentials. Is there a some way to add DNS record automatically ? I tried to add DNS record for subdomains on test server with wildcard (*.tester) and that seems to work for some time but that change coused some bad problems in our domain network and admin forbid me to mess with DNS, he said that I have to add DNS record for every subdomain manually and that I can not use wildcards, and there is nothing that I can do about it, mainly for "politicall" reasons :( obviously our admin is pretty much uncooperative, outsorced from different organization and I can't do anything about that. can I add another DNS server on that machine ? What must be setup on clients machines to "tell" them to use domain DNS server and tester domain server ? So please I need someone to give me some advice, what should I do ? Is different port numbers only option left ? Thanks !

  • Windows 7 not booting up and stuck at startup repair

    - by mikimr
    I've been having issues with Windows 7 Home Premium on a Lenovo laptop. At first, it would not start up normally at all. I started it in Safe Mode, where I disabled all non-MS services and tried again to no avail. It then goes into Startup repair where it failed several times. I tried copying the original registry settings, still the same. I resorted to booting with an Ubuntu DVD, where I ran the boot-repair, where it is supposed to correct the Windows boot. No luck. I used Win7 DVD to start up from there, where I had the option to install or repair. I chose the repair, got into command prompt, ran chkdsk /i /r, where it found 3 unreadable segments, went through the 2nd step without issues, and the 3rd step completed with some errors (can't recall the exact errors). When I restarted the machine, it went to straight to the Stratup Repair, indicating "Attempting repairs... Repairing dis errors. This might take over an hour to complete." It's been like this for nearly 15 hours. When I try to cancel or close the Startup Repair window, I get a message "The current repair operation cannot be cancelled." Should I let it run or force shut the machine? If force shut, how can I resolve this problem? Thanks.

  • How can virtualization be efficient?

    - by pestaa
    As I understand, the virtual machine and the guest OS doubles the amount of abstraction layers (that are computationally relevant) between the user interface and the pure power of the hardware. Some of the said abstraction layers are (emulated) hardware, drivers, IO interfaces, etc. Top-notch virtualization solutions like Xen probably eliminate a few of these complexities, but I still wonder how efficiency is achieved in these environments; and whether manageable cloud servers are really worth the performance price.

  • How to prevent an SSD from disappearing from BIOS

    - by Midimatt
    I've only recently upgraded my old machine to a new one with a brand new 60gb SSD as my boot drive and a 1TB main drive. Paranoid about completely breaking my SSD, I read up on a lot of issues that I needed to watch out for, including making sure AHCI was turned on and trim enabled. PC has been working fine for a few weeks now, until today. My wife was watching some TV on the machine when it started to act strange and eventually blue screened. She rebooted and the boot mgr was missing. When I got home from work I checked the BIOS and the drive had disappeared. I panicked and looked up some possible fixes, and I discovered a large amount of people having problems with the drive firmware, especially on OCZ Vertex and Agility drives, and my drive is an Agility 3 drive. The problems included blue screens followed by missing drives, and a solution was to reset the CMOS and try again. This worked, and now everything seems to be working fine. My question is, is there any way to prevent this from happening? Am I missing a setting for my SSD? All of the posts I found were from early to mid-2011 nothing for the end of 2011 to 2012. So I am wondering if I've missed anything. EDIT: Checked my drives firmware and it is 2.15, which has had issues reported by users.

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

    - by transistor1
    I recently set up a "micro" size Windows 2008 Datacenter server on Amazon AWS. My small group needs several concurrent RDS users to be able to access the machine. Without installing the "Remote Desktop Server" role, it allows 2 concurrent connections. I read on MS' website that in order to set up multiple users, we needed to install the RDS role. I did so, but now the application we are trying to share is running much slower than it was before. Prior to the role installation, it was taking about 5 seconds to open; now it is taking a few minutes to open -- without any other users logged on except me. My assumption is that the RDS role may be too much for this micro instance to handle, and currently, changing to another size instance is not an option (it may be possible later if we were to receive enough funding). This leads me to the following questions: 1) Is it a sensible assessment to assume that it is the RDS role is slowing things down, or are there other things that I could look at to speed it up? We are talking about a machine with ~600MB of memory. 2) If I revert back to the pre-RDS role, is there any legitimate way (in terms of purchasing RDS licenses) to get more than 2 concurrent desktops? I did read this, and am not questioning that the answerer is knowlegeable; but someone else may have some other experience. I am also making it clear that we want to do this in a legitimate way. Thanks in advance for any assistance that can be provided! EDIT: if it is helpful in answering the question, the application in question is a Lotus Approach database. Also, I am asking this from a technical perspective: not a legal one. I want to know if it is possible to install valid licenses without the RDS role.

  • What is the risk of introducing non standard image machines to a corporate environment

    - by Troy Hunt
    I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.

  • Is there any way to shut up my ATI HD 5770?

    - by slpsys
    So to preface, I basically built Jeff's machine; I already had some of the components, including (scarily enough) the exact same case1. I've been buying bits and pieces over the past few months, which coincided perfectly with his recent post about three monitors, though not being a gamer outright, I opted for the second-from-the-bottom option. After finally plopping all the pieces lovingly into the case this evening, I turn it on...and it sounds like four professional grade hair-driers. Some quick regression analysis determined that with the video card out, the running machine sounded no louder than our house's vents. Basically, my last desktop build included a $45-at-the-time graphics card, and it's been Macbook Pros and workstations since then, so I have zero idea whether I'll just be able to tune the fan speed later on. Will I be able to get this thing to quiet down every time I'm not playing Modern Warfare 2 at maximum framerate, or should I just send this thing back now, and get the quietest card in my pricerange? 1 One thing of note is that I do not have noise-absorbing foam in the case, as is pictured in the article. I'm only mentioning that because I suspect it could drop the overall output a few decibels, but obviously not that many.

  • Suggestions for making sysfs parameters persist across reboots

    - by ewwhite
    I'm experimenting with large changes to Linux system runtime parameters exposed through the sysfs virtual file system. What is the most efficient way to maintain these parameters so that they persist across reboots on a RHEL/CentOS-style system? Is it simply dumping commands into /etc/rc.local? Is there an init script that's well-suited for this? I'm also thinking about standardization from a configuration management perspective. Is there a clean sysfs equivalent to sysctl?

  • Help with routing table

    - by user68752
    I have tried to find the answer to my question but not really found a clean and easy solution. I have a box (Ubuntu headless 10.04.1 server, with one Ethernet port) on LAN behind a router (running m0n0wall), that I have successfully installed a PPTP device (ppp0) on, this is working flawlessly (following this link) The thing is I want this box to route all it's internet traffic through the VPN tunnel (ppp0 device) but also being able to access the local LAN on 192.168.1.* subnet. I've succeeded a bit with this, but my problem right now is that I have port forwards (e.g. SSH) done in the m0n0wall pointing to this specific box which forces me to do "add routes" to all boxes that want to access this machine through this specific port. For instance a machine with ip xyz.xyz.xyz.xyz needs to have a static route setup in the routing table on the box to be able to access the box. This is the result of route -n xxx.xxx.137.2 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0 xxx.xxx.137.2 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 yyy.yyy.0.0 192.168.1.1 255.255.0.0 UG 0 0 0 eth0 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 Where xxx is the IPs provided from VPN server. yyy.yyy.0.0 is a net that i want to have access to the box, without this I can't access the box from outside the LAN (via port-forwards done in router software, m0n0wall) is there away round this ugly solution?

  • Euro character messed up during FTP transfer

    - by djechelon
    My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

  • how to set windows 7 resolution to 16:9 in virtualbox running in ubuntu 12.04 as a host?

    - by Gabriele
    I have installed Virtualbox in Ubuntu 12.04, and I created a virtual guest with Windows 7 64bit. Guest additions were also installed. It works fine, but I can't set the resolution to anything higher than 1600 x 1200, whereas my screen is 1920x1080. Here's my system specifications: Intel(R) Core(TM) i7-3632QM CPU @ 2.20GHz AMD Radeon 7650 VGA 8 Gb RAM DDR3 Moreover, if I try to enhable 3D acceleration in the settings of my guest, when I expand to full screen it aborts...

  • Nginx https rewrite turns POST to GET

    - by x7311
    My proxy server runs on ip A and this is how people access my web service. The nginx configuration will redirect to a virtual machine on ip B. For the proxy server on IP A, I have this in my sites-available server { listen 443; ssl on; ssl_certificate nginx.pem; ssl_certificate_key nginx.key; client_max_body_size 200M; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } server { listen 80; rewrite ^(.*) https://$http_host$1 permanent; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } The proxy_redirect was taken from how do I get nginx to forward HTTP POST requests via rewrite? Everything that hits the public IP will hit 443 because of the rewrite. Internally, we are forwarding to 80 on the virtual machine. But when I run a python script such as the one below to test our configuration import requests data = {'username': '....', 'password': '.....'} url = 'http://IP_A/api/service/signup' res = requests.post(url, data=data, verify=False) print res print res.json print res.status_code print res.headers I am getting a 405 Method Not Allowed. In nginx we found that when it hit the internal server, the internal nginx was getting a GET request, even though in the original header we did a POST (this was shown in the Python script). So it seems like rewrite has problem. Any idea how to fix this? When I commented out the rewrite, it hits 80 for sure, and it went through. Since rewrite was able to talk to our internal server, so rewrite itself has no issue. It's just the rewrite dropped POST to GET. Thank you! (This will also be asked on Nginx forum because this is a critical blocker...)

  • Bizarre client IP switch-up on VPN

    - by B. VB.
    Let A.B.C.D be the public IP of my VPN server. Let W.X.Y.Z be the IP of the client before it connects to the VPN. My VPN server's IP address on the LAN in 10.8.0.1, and the client is 10.8.0.6. I also run a webserver on the same machine hosting the VPN. On it is a simple webpage that performs the exact same thing as whatismyip.org (i.e., simply prints the IP of the requester) Let me illustrate the scenario for you. In a Chrome window I have three tabs, what I have in parenthesis is the URL: Tab 1 (http://whatismyip.org): A.B.C.D This is what I expect to see. It's the public IP of the VPN server. Tab 2 (http://10.8.0.1): 10.8.0.6 ok, looks expected. They are behind the same LAN now. Tab 3 (http://A.B.C.D) W.X.Y.Z WTF?? Basically, if I access the webserver while tunneled, in shows the IP address of my machine PRIOR to tunelling! Remember, tab2 and tab3 are the same webpage. Why does Tab3 not show the client IP as it's own IP (i.e., show A.B.C.D)??? I hope this question is clear, thanks in advance!

  • Hibernate & Sleep broken after IE 9 RTM installation in Windows 7 x64.

    - by AKa
    I have a question about hibernation. I installed Internet Explorer 9 RTM x64 on my Windows 7 x64 SP1 desktop machine. After this, computer don't entry the hibernation or (hybrid) sleep state properly. After I hibernate the computer the monitor become blank screen and the keyboard and mouse are inactive. But the machine is still running and there isn't any possibility to switch them off as only with power button. But this is recognized on next start as ineligible because of log entry with message “The previous system shutdown at xx:xx:xx on ?xx.?xx.?x was unexpected“ and menu with safe mode option. I’m clearly not sure if it has something to do with Internet Explorer installation, but I’m definitely guaranteed that before of this I never had some problems with hibernation or (hybrid) sleep. In Windows logs isn’t something suspect. I switched the hibernation off and on, installed new drivers for mainboard, graphic and network card, checked the hard disk, nothing was helpful. This is really sad, beacuse I don't like to switch the computer completely off because it takes longer to boot. Any suggestions?

  • File corruption (bad checksums) in large files copied to VMware guest

    - by AllanA
    In setting up a development lab, I've got a desktop system running ESXi 4.1.0 (free license) on SATA RAID 0 (already purchased and configured when I started this job; I'm open to hardware input as it pertains to my problem.) Its guests so far include two Win2008 Server R2 64-bit VMs and on Ubuntu 10.04 64-bit VM. I'm installing onto the Windows servers. We've been copying off some fairly large files (over a gigabyte) for an installation, hoping to install more quickly from a (virtual) hard drive than from the network for from BD-ROM. The problem is that they keep coming up with different checksums from the originals. The file sizes are the same, but md5sum reports different numbers (and so does the installer, as it refuses to continue when the checksums don't match.) I've tried copying directly from the BD-ROM (attaching the OS drive to the host system's physical drive). I've tried copying the large files onto a co-worker's Windows machine from his Blu-Ray drive; when I do that, the checksums match. But when I copy from his machine to the VM guest over a network share, the checksums no longer match. Thinking this meant a corrupt destination drive, I deleted it in vSphere and added another freshly created drive. The problem persists. I'm not sure what to try next.

  • Increase Linux screen resolution

    - by David Gard
    I'm running an install of CentOS 5.5 virtually and for some reason I only have 2 available screen resolutions - 800x600 and 640x480. Does anybody know how I can add some bigger resolutions? I've had a look in /etc/X11/xorg.conf and it is knows that the graphics card is virtual, but even listing the resolutions that I want fails. Here is the default screen section - Secton "Screen" Identifiew "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection And here is what I tried adding to SubSection "Display" - Mode "1024x768" "1280x1024"

  • Application Screen Repainting Issues

    - by Jeff Sheldon
    I have this issue lately at work. It drives be nuts, and I finally stopped to ask this question. It's quite often that an application I've been running just randomly fails to repaint itself for a while, usually in the editor screen. I most often see this occurring with Expression Web, Visual Studio 2008/2010 and SQL Server Management studio. These applications are what I work in the most, so I'm not surprised to mostly see it here. But I was curious if anyone else had a solution for this. I've tried: Reboots. The screen shot below is about 10 minutes after a reboot. New Video Drivers. This machine is running a Nvidia Quadro NVS 290 video card with the latest drivers. Closing other applications, this is the only thing running right now. As far as hardware, this machine has Dual Quad-Core Xeon 2.83ghz Processors, with 10 gigs of memory, running Windows XP SP3 64bit. Any help would be great. JNK EDIT: Per comments from deleted (wrong) answer: I'm running dual monitors. Set it to single display, still occurred. Rebooted, and tried it again, and it still occurred. Switched it back to dual screen. My resolution is only 1400x900 on each.
