  • Having an issue trying to get Gigabit speed across my network (Ubuntu Server)

    - by user94217
    I've just started looking into the network speeds at my office, the entire network is setup to be "Gigabit". This includes Gb switches, Gb Network cards and Cat 5e cabling. I'm not expecting the full speed, I just want more than ~90 Mb/s. I've been running some tests with iperf the linux tools and checking the hardware with ethtool. I have 3 servers and when doing my checks/test I discovered that the two backup servers can access each other at around 450 Mb/s but when using either one of them to connect and test the main server, I only get the 90Mb/s even though ethtool shows the networking card running at 1000/Full. The only difference between all the server/networking cards is the "Port" which ethtool shows. On the two backup servers the "Port" is shown as MII yet on the other it's shown as "Twisted Pair". When using ethtool -s to manually set the "Port" to MII on the main server, it looses all connectivity and does not show "Speed" or "Duplex". Anyway, Am i doing something wrong? Is there a specific reason my main server cannot use Gb when there appears to be no difference except the "Port"?

  • Having an issue with Java/ minecraft (Windows 7 64bit)

    - by MetroGnome
    I have had issues with java on my computer for a while. First of all, java has never worked on Google Chrome or Firefox, Only IE. Whenever I need to use Java, I use IE. Now, I just tried to play minecraft the other week and I receive the error "fatal error (1)" and get a black screen (this is on the online free version). Now, I searched for java and found that I have Java 32 bit. I cannot uninstall it on Revo uninstaller or Windows uninstaller. What should I do?

  • Windows 7 Task bar + Chrome tab Issue

    - by mikelbring
    When you have say more then one file or something open or window (not tabs), the windows 7 task bar combines or stacks them on top of each other. Well my chrome started to do that with tabs. It looks like I have more then one chrome window open, but its just tabs all in one window. So when I click on the stacked chrome on my task bar it shows a preview of each tab and then goes to that tab. I would much rather have it be one chrome icon rather then stacked and then I can select my tab. The preview for the many tabs I have open is annoying me. I know this has to be something I accidental turned on because it did not do this before nor does it do it on my other computers. Thank you.

  • Backup Mongodb on EC2 through EBS snapshots - timing issue

    - by DmitrySemenov
    I'm following this guidance http://docs.mongodb.org/ecosystem/tutorial/backup-and-restore-mongodb-on-amazon-ec2/ I have 4 EBS 1000 IOPS volumes assigned to instance These 4 volumes through MDADM assembled into software RAID10 array. I want to do backups through EBS Snapshots as explained in the article above Question: Mongodb says - that I need to mongo shelldb.runCommand({fsync:1,lock:1}); -- this will lock the db for writing ....run snapshot creation... mongo shell db.$cmd.sys.unlock.findOne(); -- this will unlock the db for writing so do I need to unlock the DB for writing after I issued the comand ec2-create-snapshot or after it's finished and the actual snapshot is created thanks, Dmitry

  • Network Performance issue

    - by qubemarker
    We have three Ubuntu 10.04 servers. One server is a storage server and the other two servers are configured as clients. The storage server has a good amount of capacity and it is integrated with windows Active directory server for Authentication. I am uploading some video files from both clients to the server and when I am uploading data from any one client alone I get about 26 MB/s data transfer rate. When I upload data from both the clients simultaneously I am only getting about 8 MB/s from each client. I have gigabit ethernet cards in all of the servers and a L2 Managed gigabit switch for connectivity. I don’t know why the data transfer rate is decreasing so much in simultaneous read and write. I have tried all of the TCP stack related settings suggested here. Can any assist with getting better read/write performance out of this setup? Any help is appreciated.

  • http 301 redirection issue

    - by Guilhem Soulas
    I'm a little bit lost with a redirection. I want mysite.com, www.mysite.com and www.mysite.co.uk to redirect to mysite.co.uk. In Apache, I wrote this for mysite.co.uk in order to redirect www to the root domain: RewriteEngine on RewriteCond %{HTTP_HOST} ^www RewriteRule ^/(.*) http://mysite.co.uk/$1 [L,R=301] And for mysite.com, I wrote this redirect to mysite.co.uk: ServerName www.mysite.com RewriteEngine on RewriteRule ^/(.*) http://mysite.co.uk/$1 [L,R=301] This way, I can make the redirection work properly from www.mysite.com to mysite.co.uk, but it doesn't work for mysite.com too mysite.co.uk (without the www) at the same time. Could someone tell me how to make all my redirections work in all cases?

  • Specific issue on data pump API in oracle

    - by Median Hilal
    I have a client/server architecture. Using an Oracle dbms on the database server side. I need to perform a user-triggered (from client side) backup of the database, where the best way to perform that is using a stored procedure on the server side which the client may call, as the client has no oracle tools to perform the backup. I've searched thorough inside available solutions and have found that using a stored procedure is the best way. Well, then I found that using oracle data pump API is the best way to use inside a PL/SQl stored procedure. My specific questions about the API are... I would like to ask about two issues ... ---- The first ----- the detach function to detach the handler, is it necessary to be used at the end of the procedure? and what if I don't use it? I read the Oracle documentation but I didn't get their point, they say it doesn't terminate the job but indicates that the user is not interested in it, an when I use detach at the end of my procedure the exported .dmp file disappears. ---- The second ----- to perform a user (client side) triggered back up as the modification are only to the data, I used TABLE parameter for the export operation. But the version parameter... what should it be? I also read the documentation but couldn't determine what I need (LATEST or COMPATIBLE) ? Thanks

  • CPU Configuration Issue for 2 Servers (Server 2008 R2)

    - by Bill Moreland
    I have 2 servers running the exact same Classic ASP code with Access DBs (yes, not ideal, but it is what it is, for now). 1) Xeon 5520 @ 2.27 GHz (6 GB Memory) 2) Xeon E5-2620 @ 2.00 GHz (2 processors, 32 GB Memory) For most pages the newer E5-2620 processes the pages between 10-15% faster. On pages requiring heavy and/or multiple complicated access stored procedures (queries) the older 5520 does a much better job. I believe the servers are configured nearly identically. My question: is it possible that the newer, multi-processor server is not as good at handling Classic ASP as the older single processor? Is there a configuration difference that needs to be in place that I'm missing since I'm shooting for identical implementations?

  • OpenVPN and brouting issue

    - by JavierMartinz
    I have a Guest XEN Machine in which I want to connect by OpenVPN to other network. But I have this problem: when I want to connect to that OpenVPN I get a lot of TLS handshake errors because I think that the packages did not come rightly. When, at the end, the guest machine achieve to connect (after several tries) I can't ping the other machines of the OpenVPN network. Except sometimes, where if I ping 20 times MAYBE i get ping-answer in 1-2 times. I think that this problem is related about how the HOST Xen machine 'filters' the packages to the bridge. I mean, I think that all the outgoing guest machines packages are good but the incoming traffic to the guests is not recognized well. How could I detect/solve the problem? Im using Debian Linux in both machines

    I'm having a bit of a problem with using three monitors with VMWare Workstation 10. When only two monitors are enabled in the system I have an option to "Cycle Multiple Monitors", available from the View menu (in full screen). When I enable the third monitor that option is no longer in the menu and I can only use one monitor at a time. I've found this article and a "Choose a Monitor Layout" button is mentioned there but I'm unable to see it anywhere. I'm using Windows 8.1 as the host and Ubuntu 14.04 as the guest. The graphics card is AMD Radeon R9 290x with latest beta drivers

  • Twisted pair cable twists and unwanted signals issue

    - by ziaharipur
    I am confused about one point I have read the following paragraph from the networking book. “the twists in the twisted pair cable are used to avoid the unwanted signals. For example one twist, one wire is closer to the noise source and the other is farther; in the next twist the reverse is true. Twisting makes its probable that both wires are equally affected by the unwanted signal. This means that the receiver which calculate the difference between the two receives no unwanted signal.” Now ok I understood the purpose of twists but I am confused about how receiver will calculate the difference when it will receive the signal?. How unwanted signal will be eliminated ? Another thing that I want to make clear is , I am beginner please provide such an answer that can be understood.

  • Sed issue with numbers exceeding 9

    - by Imane Fateh
    May be my problem is kinda obvious for you but I really need to get a solution. I need to generate a file.sql file from a file.csv, so I use this command : cat file.csv |sed "s/\(.*\),\(.*\)/insert into table(value1, value2) values\('\1','\2'\);/g" > file.sql It works perfectly, but when the values exceed 9 (for example for \10, \11 etc...) it takes consideration of only the first number (which is \1 in this case) and ignores the rest. I want to know if I missed something or if there is another way to do it. Thank you ! EDIT : The not working example : My file.csv looks like 2013-04-01 04:00:52,2,37,74,40233964,3860,0,0,4878,174,3,0,0,3598,27.00,27 What I get insert into table val1,val2,val3,val4,val5,val6,val7,val8,val9,val10,val11,val12,val13,val14,val15,val16 values ('2013-04-01 07:39:43',2,37,74,36526530,3877,0,0,6080,2013-04-01 07:39:430,2013-04-01 07:39:431,2013-04-01 07:39:432,2013-04-01 07:39:433,2013-04-01 07:39:434,2013-04-01 07:39:435,2013-04-01 07:39:436); After the ninth element I get the first one instead of the 10th,11th etc...

    - by jmassic
    I have a CentOS server configured as a PPTP VPN Server. The client is a Windows 7 with "Use default gateway on remote network" in advanced TCP/IPv4 properties enable. He can connect to CentOS without any problem and can access to: The Box of his ISP (http://192.168.1.254/) The CentOS server The website which is hosted by the server (through http://) But he canNOT access any other web service (google.com or 74.125.230.224) I am a beginner with web servers so I do not know what can cause this problem. Note 0 : The Windows 7 user must be able to access the whole internet through the CentOS PPTP proxy. Note 1 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED it is the same problem Note 2 : With "Use default gateway on remote network" in advanced TCP/IPv4 UNCHECKED AND "disable class based route addition" CHECKED the Win 7 can access google but with the ISP IP (no use of the VPN...)

  • Strange network issue (ZIP file fails CRC test over VPN)

    - by Joe Schmoe
    We have a server in the office running Windows Server 2003 Our office is connected to our datacenter via hardware VPN (Linksys RV082 router in the office to CISCO router in the datacenter). There is a job that runs on the server in the office that does following: ZIP certain files from the server using 7Zip, copy ZIP file to a network share in the office and verify ZIP integrity, copy ZIP file to a network share in the data center and verify ZIP integrity. Problem is - verifying ZIP integrity for the file in the data center always fails. However, if I run 7Zip on the server in data center that exposes that share ZIP file verifies just fine, so it is not actually corrupted during copy operation. Additionally, I tried running ZIP on other computers in the office to verify ZIP file on datacenter file share and it verifies OK. I tried plugging server to the same network port where my workstation is connected using different cable (my workstation doesn't exhibit this problem) and ZIP verification still fails. So the problem is local to that specific server. On network adapter properties for the server in question there is no "Advanced" tab where one can usually configure a lot of network settings. Network card driver is up to date (Windows Update doesn't find anything newer and Lenovo website doesn't have any drivers for Windows 2003 for this computer model). Is there any other way to configure network setting via command line? What settings could be relevant to this problem?

    Certificate request process works fine. Once the certificate is received from VeriSign, the installation process also works fine (no errors.) However, once installed, the new certificate is not "assigned." Meaning, when I view the IIS instance security properties, it still shows the previous certificate start & end dates. Thoughts? Windows 2003, Web Edition. I have 3 other Win2003WE machines, configured nearly the same, and do not have this problem.

  • Y560 Lenovo IdeaPad bandwidth issue

    - by Vlakarados
    I have a Y560 Lenovo IdeaPad, my config: i7 740QM, 4GB RAM, RADEON HD 6570m/5700 1024MB and my network adapter is Intel WIFI Link 5150. The laptop is 2 years old and the problem I'm about to describe is present from the first day. As may be seen here, the receive bandwidth should be up to 300 Mbps, but the maximum download speed from LAN and using torrents is about 2.4MB/s. My internet connection is 100Mbps and other laptops in my house have the appropriate download speed - up to 12MB/s, I have tested at my friends house and at my job, the speed remains the same. I have tried all possible configurations I could think of in network settings - nothing helps. I use Windows 7 and I have had installed different versions (Ultimate, Professional, Home, OEM Home, 64 and 32 bit versions). Some time ago I searched for the problem and found one or two threads that had the same problem and there were something said about a limitation in firmware that some experienced users have managed to bypass. Updating drivers didn't help me either. Is there any reliable way to fix this?

  • VirtualBox Shared Folder encoding issue

    - by Somebody
    I'm using Ubuntu in Virtualbox and have a shared folder mounted to Virtualbox which i'm accessing inside Ubuntu. The problem is, that when i'm editing and saving some files from shared folder in Windows it's getting some strange symbols at the end of edited file. There must be some encoding issues. Doesn't Virtualbox automatically converts files to Unix standards? To fix that, i have to re-mount shared folder inside Ubuntu each time i'm editing some file. Any solution to avoid re-mounting each time I edit? I'm mounting like that: mount -t vboxsf SVN /opt/htdocs/ Thanks.
