  • Drivers not installing and drives not being recognized

    - by jab818
    Dell optiplex 755 running win7-32 Two problems, not sure if they're related 1: Two drivers are missing when viewing device manager, PCI serial port and PCI Simple Communications Controller, I've searched dell's site, and the internet as a whole and have been wholly unable to find the drivers. 2: I'm unable to connect any external hard drives, but any flash drives plugged in will be recognized and accessible by the computer without issue. Any help would be appreciated.

  • Puppet's automatically generated certificates failing

    - by gparent
    I am running a default configuration of Puppet on Debian Squeeze 6.0.4. The server's FQDN is master.example.com. The client's FQDN is client.example.com. I am able to contact the puppet master and send a CSR. I sign it using puppetca -sa but the client will still not connect. Date of both machines is within 2 seconds of Tue Apr 3 20:59:00 UTC 2012 as I wrote this sentence.

  • Splitting Servers into Two Groups

    - by Matt Hanson
    At our organization, we're looking at implementing some sort of informal internal policy for server maintenance. What we're looking at doing is completing maintenance on our entire server pool every two months; each month we'll do half of the servers. What I'm trying to figure out is some way to split the servers into the two groups. Our naming convention isn't much to be desired (but getting better) so by name or number doesn't really work. I can easily take a list of all the servers and split them in two, but with new servers are being added constantly, and old ones retired, that list would be a headache to maintain. I'd like to look at any given server and know if it should have its maintenance done this month or next. For example, it would be nice to look at the serial number. If it started with an even number, then it gets maintenance done on even months and vice-versa. This example won't work though as a little over half of the servers are virtual. Any ideas?

  • SQL Server 2005 standard filegroups / files for performance on SAN

    - by Blootac
    I submitted this to stack overflow (here) but realised it should really be on serverfault. so apologies for the incorrect and duplicate posting: Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

  • Simple way to make wired internet wireless without router

    - by Anriëtte Combrink
    Hi there Is there any device which you can plug into an Ethernet port and then have it broadcast the internet connection it receives through Ethernet wirelessly with a set password (maybe a serial number on device itself)? The problem is, I have a Wi-fi capable device, an iPhone and I want to use the wired internet connection in a hotel room, but the iPhone needs a Wi-fi signal. How can I accomplish this with a rather simplistic device. // EDIT: Can this be achieved with an Apple Airport Express?

  • Mysql Cluster not working on Ubuntu

    - by user53864
    I am unable to setup MySQL Cluster on ubuntu servers. As a starting point I started from the link but I am not successful and the tar ball version I download is 6.3.45. As I wanted to test the mysql cluster, the Data node and SQL node are same but sql never appeared as connected in management node console and it looks like below. [ndbd(NDB)] 2 node(s) id=2 @192.168.1.107 (Version: version number, Nodegroup: 0, Master) id=3 @192.168.1.108 (Version: version number, Nodegroup: 0) [ndb_mgmd(MGM)] 1 node(s) id=1 @192.168.1.105 (Version: version number) [mysqld(API)] 2 node(s) id=4 (not connected, accepting connect from 192.168.1.107) id=5 (not connected, accepting connect from 192.168.1.108) On all the 3 machines mysql-server & client(apt-get install mysql-server mysql-client) were already installed and I completely stopped and also removed them at the system start up. Now the mysqld is from extracted cluster tar ball(/usr/local/mysql/support-files/mysql.server). As for testing, I created a test database on both the data nodes but the tables are also not syncing on other node. I checked many links, configurations are remained similar in all the links but somewhere it's going wrong. Anymore extra package is required?, Could anyone help me here..?. I am trying this for past 3 days... Thank you!

  • Referencing SQL Server 2008 R2 SMO from Visual Studio 2010

    - by user69508
    Hello. We read a number of things about referencing SQL Server SMO from Visual Studio but still don't have the definite answers we need. So, here it goes... A number of years ago we created a C# application using Visual Studio 2005 and SQL Server 2005. In that application, we added .NET references to a number of SQL Server SMO objects, and everything worked fine. Those references were: Microsoft.SqlServer.ConnectionInfo GAC 9.0.242.0 Microsoft.SqlServer.Smo GAC 9.0.242.0 Microsoft.SqlServer.SqlEnum GAC 9.0.242.0 We have now migrated to Visual Studio 2010 and SQL Server 2008 R2. However, when we try to reference those same SMO objects for SQL Server 2008 R2, they don't appear in the .NET references tab. We're wanting to reference the SQL Server 2008 R2 version of those same SMO assemblies for our upgraded C# application. On our development machines, we have SQL Server 2008 R2 Developer installed with all options, including the SDK such that the assemblies are found in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, my first questions are: Are we supposed to do file references to the SMO assemblies instead of .NET references in Visual Studio 2010 w/ SQL Server 2008 R2? Or, is there some problem with our development machines such that the SMO assemblies are not appearing in the .NET references tab? Next, our production machines will have SQL Server 2008 R2 Workgroup installed with the client tools option selected, thus providing those same SMO assemblies in C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies. So, the next questions are: When we release to production, are we supposed to redistribute the SMO assemblies with our application? Or, will our application work on the production servers without redistributing the SMO assemblies (since the client tools/SMO assemblies have been installed)? What else????? Thanks for the help!

  • How do I redirect the kernel console output on Ubuntu 10.04

    - by lorin
    When I reboot my Ubuntu 10.04 nodes, I'd like to be able to see the kernel boot messages when connecting to the IPMI interfaces using Serial Over LAN mode (ttyS0). What do I need to do to be able to redirect these messages to ttyS0? Ideally, I'd like them to also still appear in the usual place (tty0, I think) for when I plug a monitor directly into the box.

I am using centOS 6..4 for making DNS i applied following steps: changed the host name = abc.zoom.com and domain name = zoom.com. then did changes in the named.rfc.1912 file as per rename named.localhost = forward and named.loopback = reverse in forward lookups i changed zone "zoom.com" IN { type master; file "forward"; allow-update { none; }; and in reverse lookups i changed zone "x.168.192.in-addr.arpa" IN { type master; file "reverse"; allow-update { none; }; and then did changes in the named.conf file options { listen-on port 53 {192.168.x.x;}; listen-on-v6 port 53 { ::1; }; directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; memstatistics-file "/var/named/data/named_mem_stats.txt"; allow-query {any;}; recursion yes; 192.168.x.x is my local DNS address. then i copied lookups file in /var/named and edited the file "forward" $TTL 1D @ IN SOA abc.zoom.com. rahul.abc.zoom.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS abc.zoom.com. abc A 192.168.x.x and for " reverse" $TTL 1D @ IN SOA abc.zoom.com. rahul.abc.zoom.com.( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS abc.zoom.com. x PTR abc.zoom.com. when i put the public ip details in the Eth0 it was automatically redirect in to the resolve.conf when i checked through dig command the answer, query all were 1. my system is itself a Software router.In gateway of my all local machine i give my system ip address. however my DNS and Gateway IP is same. Now the problem is that. i gave the static ips to all my local machines when i give the DNS which i made i.e 192.168.x.x that time my ftp is not connect in filezilla software E.g: host : pqr.zoom.com ("zoom.com" is my local domain name) username : pqr password : pqr gives an error: Error: Connection timed out Error: Could not connect to server but if i give the public DNS address it get connected. i want to solve this problem please give solution on this.

  • MySQL-Cluster or Multi-Master for production? Performance issues?

    - by Phillip Oldham
    We are expanding our network of webservers on EC2 to a number of different regions and currently use master/slave replication. We've found that over the past couple of months our slave has stopped replicating a number of times which required us to clear the db and initialise the replication again. As we're now looking to have servers in 3 different regions we're a little concerned about these MySQL replication errors. We believe they're due to auto_increment values, so we're considering a number of approaches to quell these errors and stabilise replication: Multi-Master replication; 3 masters (one in each region), with the relevant auto_increment offsets, regularly backing up to S3. Or, MySQL-Cluster; 3 nodes (one in each region) with a separate management node which will also aggregate logs and statistics. After investigating it seems they both have down-sides (replication errors for the former, performance issues for the latter). We believe the cluster approach would allow us to manage and add new nodes more easily than the Multi-Master route, and would reduce/eliminate the replication issues we're currently seeing. But performance is a priority. Are the performance issues of MySQL-Cluster as bad as people say?

  • Export firewall rules on Juniper SSG-550

    - by Gumble
    I'd like to export all the policies set up in my Juniper SSG-550 running JunOS 5.1 but i can't find any way to do so. Preferably in an easy to parse format (csv would be great). Problem is the firmware is awfully outdated and I only have access to the webGUI, maybe there's a way to do that through the serial port but I just can't have acces to it. Thanks in advance !

  • HP DL 380G7 Raid swap drives

    - by dean
    disks 0 and 1 are raid redundant (OS) and the remaining 6 drives are in raid 5 I believe. i would like to pull out disks 0 and 1 and install new drives to build a new OS. I need to be able to reinsert the old drives and reboot back to the original OS. (swap) I had a serious problem in the past attempting this. does the raid require (look for) the drives based on a serial number or something? just dont want to lose data. thanks

  • SQL Server 2005 standard filegroups / files for performance on SAN

    - by Blootac
    Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

  • How is the Windows 7 activation going to be?

    - by Donny V
    I really hated the Windows Vista activation system Microsoft had. I hope that Windows 7 is going to go back to the simple serial key like Windows XP. You couldn't even upgrade hardware without Windows Vista bitching. What is the activation system they're using for Windows 7?

    I have set, under "Main" - "IDE Configuration" - "Configure SATA as" to "Raid" and "Onboard Serial-ATA BootRom" to "Enabled", but upon POST I still do not see the Intel Matrix Storage Manager screen where I can press Ctrl+I to set up my raid?

  • FreeBSD 8.1 unstable network connection

    - by frankcheong
    I have three FreeBSD 8.1 running on three different hardware and therefore consist of different network adapter as well (bce, bge and igb). I found that the network connection is kind of unstable which I have tried to scp some 10MB file and found that I cannot always get the files completed successfully. I have further checked with my network admin and he claim that the problem is being caused by the network driver which cannot support the load whereby he tried to ping using huge packet size (around 15k) and my server will drop packet consistently at a regular interval. I found that this statement may not be valid since the three server is using three different network drive and it would be quite impossible that the same problem is being caused by three different network adapter and thus different network driver. Since then I have tried to tune up the performance by playing around with the /etc/sysctl.conf figures with no luck. kern.ipc.somaxconn=1024 kern.ipc.shmall=3276800 kern.ipc.shmmax=1638400000 # Security net.inet.ip.redirect=0 net.inet.ip.sourceroute=0 net.inet.ip.accept_sourceroute=0 net.inet.icmp.maskrepl=0 net.inet.icmp.log_redirect=0 net.inet.icmp.drop_redirect=1 net.inet.tcp.drop_synfin=1 # Security net.inet.udp.blackhole=1 net.inet.tcp.blackhole=2 # Required by pf net.inet.ip.forwarding=1 #Network Performance Tuning kern.ipc.maxsockbuf=16777216 net.inet.tcp.rfc1323=1 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.recvbuf_max=16777216 # Setting specifically for 1 or even 10Gbps network net.local.stream.sendspace=262144 net.local.stream.recvspace=262144 net.inet.tcp.local_slowstart_flightsize=10 net.inet.tcp.nolocaltimewait=1 net.inet.tcp.mssdflt=1460 net.inet.tcp.sendbuf_auto=1 net.inet.tcp.sendbuf_inc=16384 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.sendspace=262144 net.inet.tcp.recvspace=262144 net.inet.udp.recvspace=262144 kern.ipc.maxsockbuf=16777216 kern.ipc.nmbclusters=32768 net.inet.tcp.delayed_ack=1 net.inet.tcp.delacktime=100 net.inet.tcp.slowstart_flightsize=179 net.inet.tcp.inflight.enable=1 net.inet.tcp.inflight.min=6144 # Reduce the cache size of slow start connection net.inet.tcp.hostcache.expire=1 Our network admin also claim that they see quite a lot of network up and down from their cisco switch log while I cannot find any up down message inside the dmesg.

  • ADSL to T1, Is it worth it for us?

    - by Jack Hickerson
    The company I work for has roughly 45-55 simultaneous users (local and remote/VPN) logged in at a given time. We currently subscribe to an ADSL connection but we have been experiencing slower upload/download speeds as our number of users increase. So, I have a few questions with regards to upgrading our connection to a t1 line. I am aware that the number of channels on a t1 line are much greater then that of our current ADSL connection, but I have heard that the number of active users on a t1 line should be no greater than ~30 for optimal performance. I would think this statement is dependent on what each user was using the connection for and could change depending on this variable. That being said, I have tried to break down how the line would be used in our organization based on our major departments: Sales (~60% of total users) - Everyday surfing, email, research, occasional streaming media Marketing (~15% of total users) - Heavy reliance on uploading/downloading, streaming media, file sharing Other (~25% of total users) - email, rare use of any connection intensive activities. I have considered keeping the ADSL for our local users and dedicating the t1 to our remote users (or vice versa) but the cost is significantly higher then what we had hoped for. All factors being equal (# of users, frequency of downloads/uploads from our current activities) Would you suspect a significant performance increase in making the transition to a t1 line from our current ADSL line? What are your thoughts or recommendations?

  • Understanding Exchange User Monitor (ExMon) Output

    - by SturdyErde
    I recently downloaded and ran ExMon while trying to troubleshoot Outlook connectivity problems due to high CPU usage on Exchange Server 2010 SP2 UR8. The tool provides a great set of data, but I have not yet figured out how to make great use of it. My first question is why the Exchange Server itself shows up as a high-use MAPI client in the ExMon data. Among the users' client versions I see build numbers listed for Outlook 2013, 2010, and yes, even 2007 clients. I also see build number 14.2.387.0, which represents Exchange Server 2010 SP2 Update Rollup 8 (+/- some other patch that makes it not quite match the UR8 number). There are many user rows that list only "::1" and/or the short hostname of my Exchange server in the 'Client IP Addresses' column. Some other columns include the end-user's actual IP address and the Exchange server's IP address. ExMon shows that it is actually Exchange Server that is utilizing the highest percentage of CPU that is used for MAPI calls. I had expected to see 1 IP address and version number for each user reported by ExMon. Instead, most records show multiple version #'s (Exchange ver and Outlook ver) and multiple IPs (Exchange IP and client IP). Can anyone explain the reason for this to me, please?

  • Performance associated with storing millions of files on NTFS

    - by Tim Brigham
    Does anyone have a method / formula, etc that I could use - hopefully based on both current and projected numbers of files - to project the 'right' length of the split and the number of nested folders? Please note that although similar it isn't quite the same as Storing a million images in the filesystem. I'm looking for a way to help make the theories outlined more generic. Assumptions I have 'some' initial number of files. This number would be arbitrary but large. Say 500k to 10m+. I have considered the underlying physical hardware disk IO requirements that would be necessary to support such an endeavor. Put another way As time progresses this store will grow. I want to have the best balance of current performance and as my needs increase. Say I double or triple my storage. I need to be able to address both current needs and projected future growth. I need to both plan ahead and not sacrifice too much of current performance. What I've come up with I'm already thinking about using a hash split every so many characters to split things out across multiple directories and keeping the trees even, very similar as outlined in the comments in the question above. It also avoids duplicate files, which would be critical over time. I'm sure that the initial folder structure would be different based on what I've outlined, and depending on the initial scale. As far as I can figure there isn't a one size fits all solution here. It would be horrendously time intensive to work something out experimentally.

I want to be able to show the number of tickets submitted divided by the number of users in each country. Any ideeas how to do that? Thank you very much, Razvan
