• Yum install problem on netsolvps server

  - by Thomas

  I tried to install yum based on http://www.wallpaperama.com/forums/how-to-install-yum-problems-installing-on-linux-redhat-fedora-commands-t471.html. my current python is 2.4.6, red hot fedora core 6, 4.1.1-28, RPM 4.4.2. I tried with the yum 3.0.1 version for my current server configuration. There is no configure file on 3.0.1 so i used make install command. All files complied without error. If I run #rpm -q yum it says "package yum is not installed". Whats the problem here on the yum installation?

• MySQL replication not working on leap day

  - by danneth

  Though out of my "core" knowledge I maintain a two-way replicated MySQL database (primary and backup). It's been working fine mostly. All changes are almost instantly replicated between the two servers. But now I've noticed something strange: I have a couple of cases where there are no replication on feb 29th. Admittedly I have not yet confirmed that all replication is lost. But all cases I've found so far have had this issue. Not too long ago I changed timezone from UTC to CET on the backup, it has been CET on the primary all along. Am I fixating on this because it happened on the leap day, or could there be something to it? The servers are both CentOS 5.4 with MySQL 5.0

• Telnet works from desktop but not Server

  - by Joe Estes

  Sending mail via smtp.gmail.com is failing on my server. I looked on some forums and people were saying to make sure you can telnet to the smtp address first. When I telnet from my server i input this and get this error: [root@localhost ~]# telnet smtp.gmail.com 465 telnet: smtp.gmail.com: Temporary failure in name resolution smtp.gmail.com: Host name lookup failure From my OS X desktop I do the same and get this: Macintosh-3:~ joe$ telnet smtp.gmail.com 465 Trying 74.125.127.109... Connected to gmail-smtp-msa.l.google.com. I'm running a fedora core 9 server with a firestarter firewall. I have turned off the firewall and the same error persists. I'm also using port forwarding from my router to this server. I have allowed forwarding for port 465 on my router as well. Can someone please help. Thanks, Joe

• Overclocking a nVIDIA GTX 660M GPU?

  - by heron1000

  I have a MSI GE60 0ND laptop with a GTX 660M GPU. When I play games like Minecraft or Portal 2, the core clock is stable at 835 MHz. Recently I tried to overclock it using MSI Afterburner but it wouldn't let me change the voltages or the clock speed no matter what I tried. Various Google searches yielded solutions that all didn't work. Is there any way I can overclock the GPU? Further Info: I have the nVIDIA 310.70 drivers and Windows 8.

• Laptop hardware recommendations for multi-platform development

  - by iama

  I am thinking of buying a laptop with the following configuration - Intel core 2 duo(or I3-330M)/ 4GB RAM/300+ GB 7200 RPM. I would like to be able to run two server VMs on this laptop with Win2K8 and Ubuntu (preferably 64 bit editions). Windows 7 will be the Host OS since that is the one that ships with the laptop. I am thinking of using VMWare player to run the two server OSs. Is this laptop good enough to run the two VMs side by side or do I need to go for a better configuration? Any suggestions? Thanks.

• What could cause Vista machines to degrade in performance?

  - by gencha

  We have installed several machines running Windows Vista at a client site. These machines run the same set of applications each day and are not operated with by any user. They mainly run a 3D application for digital signage purposes. After a few months I noticed that several machines suffer from really bad stuttering. The performance is unacceptable. At first I figured it was faulty hardware. But after putting a fresh image on them, they run perfectly fine again. These are Core i7 machines with GTX 280 graphics adapters. They should be able to handle the workload without any trouble (and they do, at least for a while). I really have no idea how to track down the source of this issue. Especially since not all of the machines display the same issue.

• Best SQL Server Configuration with this hardware.

  - by DavidStein

  I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

  I want to disable reverse DNS in Apache 2.

• Recommended CPU upgrade for Dell Vostro 220 with Intel E7300 processor?

  - by Justin Grant

  I've got a Dell Vostro 220 with an E7300 processor (Intel Core 2 Duo @ 2.66Mhz, LGA775 socket) and I'm thinking about upgrading my processor so I can run Windows Server 2008 R2 with Hyper-V, which requires Hardware Virtualization support in the processor. Yes, I know this is underpowered for a server, I'm actually using it as a desktop machine but I'd like to use Hyper-V instead of Virtual Server (which I'm using now for running VMs). I'd like to keep the same motherboard and ideally the same CPU fan and RAM too. Any suggestions for a good, relatively cheap (under $200) processor upgrade?

• sony vaio laptop - product cycles

  - by Max

  I am interested in buying a sony vaio z series laptop. But I found out that it was already released in january 2010 and doesnt have quad core cpus available. I guess there is a product update due in 2011? Has anyone knowledge of how the product cycles are with sony laptops? E. g. I know that apple updates its macbook pro series somewhat every 9 - 12 months. Is this around the same with sony? I am also wondering if the ssd drives sony uses are any good, but that could be another question...

• Simple active directory permissions issue

  - by Antonio2011a

  So I've created a domain controller (DC) as well as 3 machines (SQL-A, SQL-B, SQL-CORE). All are running Windows Server2008R2 (on virtualbox). I have successfully joined the 3 machines to the domain controller. Next I created a user in active directory called Kim_Akers who is a member of "Domain Admins", "Domain users", "Enterprise Admins" and "Schema Admins". However when I login to SQL-A for example as contso/Kim_Akers and then try and run something like the ServerManager.msc I can't do it due to lack of permissions "Windows cannot access the specified device, path or file. You may not have the appropriate permissions". What am I doing wrong that Kim_Akers doesn't have permissions to do this? Thanks.

• Problems installing Ruby 1.9.2 and rvm on Debian Lenny

  - by Dave Everitt

  I have currently have Ruby 1.9.1 (bad) and want to install 1.9.3 under rvm. However, rvm requirements gives a long list: install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion But I've hit a problem here: /# apt-get install libreadline6 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package libreadline6 ...and (I imagine after just hunting down a Debian source to download curl) finding these packages isn't going to be a picnic. Given that there are few packages to install before I can get rvm to install Ruby 1.9.3, what's a good way forward? My sources.list: deb http://archive.debian.org/debian/ lenny main contrib

• Hardware upgrade: Windows 7 bluescreens, Vista loads

  - by Daniel Schaffer

  I just did a fairly significant hardware upgrade while keeping my hard disks. The old system was a dell Optiplex 745 with an Intel Core 2 duo, LGA 775. The new system is custom built, Intel i5 750. I know you're supposed to do a clean install with a hardware upgrade like this, but I'd had success in the past doing the stealth hardware upgrade like this, so I figured I'd give it a shot. Windows 7 Ultimate 64 bit gets through the loading screen and immediately blue screens and reboots. Windows Vista Home Premium 32-bit, which I have on an old hard drive from an AMD box (!!) loads up fine. I ran through the windows memory checker just to be sure, and my memory is fine. So, is the BSOD the result of some sort of protection mechanism specific to Windows 7? Is there any hope of salvaging that install?

• Processor always at max speed

  - by Pratyush Nalam

  I am running Windows 8 Pro on an Apple MacBook Pro 9,1 Mid 2012 15 inch non retina. It has a Core i7-3720 QM CPU @ 2.6 GHz. For the past few days, I have noticed that it is constantly running at max speed which is 2.59 GHz. Before, it used to run at 1.5 - 1.8 GHz on normal usage. And, the weirder thing is that CPU usage is minimal. Screenshot: So, what is the reason for this? And is it harmful?

• Multi Monitor setup goes crazy after locking/unlocking Vista machine

  - by Farseeker

  Give me a 10-blade quad-processor quad-core Opteron centre and ask me to configure failover/load balancing and I'd be happy to, but the following problem has got me completely stumped. My Vista Business Professional machine, running Ultramon, has three monitors attached. When I lock the machine (to go to the delicious cafe around the corner), the monitor layout stays correct. When I unlock it, I watch as all my screens flicker (as they are being re-configured), and Vista chooses some crazy layout for the monitors. The most recent one is below, but it's never consistant. Any ideas what might cause this? It's Vista Business, with UltraMon 3.0 (exiting Ultramon makes no difference).

• Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

  - by Inshim

  Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

• Troubleshooting a high SQL Server Compilation/Batch-Ratio

  - by Sleepless

  I have a SQL Server (quad core x86, 4GB RAM) that constantly has almost the same values for "SQLServer:SQL Statistics: SQL compilations/sec" and "SQLServer:SQL Statistics: SQL batches/sec". This could be interpreted as a server running 100% ad hoc queries, each one of which has to be recompiled, but this is not the case here. The sys.dm_exec_query_stats DMV lists hundreds of query plans with an execution_count much larger than 1. Does anybody have any idea how to interpret / troubleshoot this phenomenon? BTW, the server's general performance counters (CPU,I/O,RAM) all show very modest utilization.

• 500 Error when using custom account for application pool in IIS 7

  - by Brownie

  I have a very simple site with only static files in IIS 7 on Windows Server 2008 SP2. When I try to access any static file I get a 500 error. If I rename an html file to have an aspx extension it works fine. The site also works fine when using the built in identity for the application pool. The problem occurs when I switch to using a custom account for the application pool. I have tried using both local and domain accounts to run the application pool under. I have given full control to these accounts on the website directory and files. Turning on tracing reveals this error message: ModuleName: IIS Web Core Notification: 2 HttpStatus: 500 HttpReason: Internal Server Error HttpSubStatus: 0 ErrorCode: 2147943746 ConfigExceptionInfo Notification: AUTHENTICATE_REQUEST ErrorCode: Either a required impersonation level was not provided, or the provided impersonation level is invalid. (0x80070542) I have not had any luck with googling the error code.

• Most suitable high availability solution

  - by Alex Bagnolini

  My company is hosting a website in a server with IIS, SQL Server and a 3rd party windows service (written in C#, source code available for amendments). We bought a new identical server, composed by: 1x Quad Core, 12GB RAM, 4x160GB SATA Raid 5, Windows Server 2008 R2 Datacenter, Public IP. We aim to put all webpages and the 3rd party windows service in an high-availability state. After some lab-testing on how to configure Failover Clustering and Hyper-V, we have deep doubts on what the "best" solution would be, by "best" meaning maintainable and able to correctly handle a physical server failure. Any suggestion on how we should configure the two servers? We don't need all the configuration's step, just an hint on the right direction to follow.

• Problems with Adobe Flash

  - by Georg Scholz

  I'm running Windows 7, 64-Bit on a Core-i5 HP Notebook. For approximately the last 3 months, I've had major problems with Adobe Flash. Flash has been uninstalled and installed again multiple times. No changes. Here is what happens in different browsers: (All browsers are in the latest version as of this post) Firefox: Doesn't work at all. This bothers me most, since FF is my favorite browser; I'm using a lot of Plugins. Have tried to de-activate all Plugins, but no change. IE and Chrome: Works, but most pages with Flash are stuck during page load for ~30 seconds. After that, everything is fine. Opera: No problems, everything working as it should. Strange, eh? Any help is highly appreciated!
