  • The vps is running, but the domain name is down ?

    - by Tom
    Hi, i created a vps on vps.net and installed CentOS 5.4 x64 LAMP , i choosed the root password and the server start running, i added my domain name in the vps domain section, also i added the two name servers on where i bought the domain name. the problem is that i still can't access the domain, so i think that's because a mistake in the DNS template that is created automatically by the vps provider, here is it : TYPE | NAME | TARGET | MX PRIORITY | ACTIONS ------------------------------------------------------------------- OA @ dns1.vps.net. NS @ dns1.vps.net. NS @ dns2.vps.net. MX @ mail.www.XXXXXXX.com. 10 delete A @ 85.128.137.292 delete A www 85.128.137.292 delete A mail 85.128.137.292 delete A webmail 85.128.137.292 delete A ftp 85.128.137.292 The vps is working fine, & i can access the webmin panel via the ip, so what's wrong with my parameters? Thanks

  • Using pre-made patch cables on a punch down block?

    - by Trevor Harrison
    I need to add a 24 port switch to my wiring closet. In the (distant) past, I usually just punched each port of the switch to a 110 block on the wall (using hand-made cables), and cross connect between that and the 110 block that has the runs to each workstation. To save time, I'm thinking of buying 12 pre-made drop cables, cutting them in half (so 24 single ended cables), and punching those to my 110 block. The things I'm worried about are wire type (ie. solid vs. strands) and color scheme. I really don't know if they use different wire types (still?), but I remember that being an issue at one point. Can anyone comment on this? (I definitely won't feel comfortable trying to punch stranded wiring on my 110 block) Also, picking up a random pre-built cable I had laying around, I noticed that the color scheme used didn't appear to be T568B, but T568A, which would clash with the rest of my wall. Anyone know of an online source that specifies these things? I've looked at www.cablesforless.com (which does have nicer prices) and www.cablestogo.com (which seem stupid expensive) so far. Cables For Less doesn't specify wiring scheme, Cables To Go does specify T568B. Both seem to specify stranded wires instead of solid.

  • Why does a wired network slow down with user increase?

    - by Ed Briscoe
    If you had a wired network, 20 PCs hooked up to a 100 Mbit/sec switch (same onboard ethernet port speed) and you were just sending some test data round. What is the technical explanation as to why 20 machines sending test data around this network to each other is slower than one to one? I mean I know a busy network means it's slower but I'm really trying to understand some more technical details. Thanks for any help

  • How to prevent hard drive from spinning down Windows 7?

    - by JL.
    I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?

  • Anytime I upload something, my internet slows down extremely. What can I do?

    - by Earlz
    Title says it all. For a bit more info though: Basically, I have Time Warner cable internet. My speeds maintain a stable 2Mbit/s upload and 20Mbit/s download with average ping times around 30ms. This crazy thing happens though when I upload anything. I went to upload a 200M file to my server today through sftp and my internet completely choked up. I speed tested it during this upload and my ping time was around 800ms, download speeds of 0.2Mbit/s and Upload speeds of 0.3Mbit/s. Note, I wasn't downloading anything during this time either. It is just straight upload. What is it that causes this phenomenon? My router is OpenBSD. Is there anything I could set up to fix this problem(by queues or some such), or is this a problem with cable internet?

  • Website with large number of users keeps going down due to memory leaks:Tomcat6 and Java 6

    - by user1766478
    We host many websites on one of our two virtual servers. We use tomcat 6 and Java 6. It is an MVC model with a hibernate like layer. The problem is, one of our biggest clients with the most number of members, keeps crashing the server every 6-8 hours(precisely in the mornings when most members login) We have been having this issue for 4 days now. Trying to figure out the problem but we suspect memory leaks. Any suggestions?

  • Is my Windows partition too far down on the disk?

    - by Trevor Alexander
    I have /boot/ on /dev/sda1 (1GB), followed by my Linux root LVM on /dev/sda2 (1.3GB). Finally, I installed Windows 7 on /dev/sda3 in the remaining 700GB of space. When I select Windows 7 in the grub menu, I get something like the following error and am thrown to grub4dos: find --set-root --ignore-floppies --ignore-cd /bootmgr Error 15: file not found Unable to locate necessary tables for adjustment. None of the options in grub4dos return anything but the above error. I heard that 1TB is the upper limit for locating Windows 7 partitions; is this true? How can I fix the above?

  • Is MozyHome Remote Backup known to slow down Windows Explorer?

    - by Kyle Estes
    Windows Explorer on my home machine is uber slow, and I suspect it is Mozy's fault. In the past Mozy has done some goofy stuff like placing file and folder icon overlays in Windows Explorer, which was really bugging me because I thought they were from TortoiseSVN (and I had uninstalled that!). Anyhow, does anyone else have Mozy installed? Is Windows Explorer really slow respond for you, say when you simply double click the hard drive to browse files? I'd also welcome any tips people might have on debugging why Windows Explorer might be slow (shell extensions known to cause problems, etc.).

  • What happens when Oracle's Enterprise Single-Sign-On database goes down? [migrated]

    - by Unai
    We're working on setting up Oracle's Enterprise Single-Sign-On with High Availability. At the moment every component provides HA except our database backend (i.e. we have just one instance). While conducting some kick-the-plug tests we learnt that the ESSO system works even with the database turned OFF. This was a nice surprise but now we need to understand what are the implications of a database failure; sure the sessions might be handled on the application servers and the policies might have been cached but... for how long? how big is this cache? what is the role of the database? I would appreciate if anyone shares her/his experience and/or points out to documentation that covers this. Thank you so much.

  • Why is FTP server slowing down the web server?

    - by user1448031
    I am running Apache and Filezilla ftp server in Windows. I've been noticing for the last few months that whenever I start up the ftp server, the websites start to run slow. When I shut off the ftp server, the websites start speeding up again. Sometimes I need to restart Apache server after shutting off the ftp server to speed up the websites. I only start ftp server whenever I need to allow remote file transfers. Other than that it's always off. I'm not sure what's happening and where to look.

  • Why does my computer slow down so much when attaching Bluetooth dongle?

    - by Jeff Yates
    I have a Bluetooth dongle and I plugged it into my work laptop (a Dell Latitude D830). Windows detects the Generic Bluetooth USB or similar and then proceeds to go incredibly slow with a process, avp.exe¹, taking 50% CPU. The System Idle process is getting most of the other 50% CPU and the avp.exe process is only at Normal priority. The machine doesn't seem to recover, so I had to turn the power off and reboot. Now, I haven't installed the drivers yet for the device, which I am doing now and I expect it to resolve the problem, so I am not asking how to fix this. I would rather know why Windows goes so slow in the first place. What is it trying to do and failing at so badly that it barely crawls? ¹ Part of Kaspersky Internet Security suite

  • Is there any program (or code, any language) that will mute all of the microphones on my computer?

    - by Sean
    Is there any program (or code, any language) that will mute all of the microphones on my computer? If it is code, please make it as simple as possible, the only language I know is C# and I am still VERY new to it. I just want to setup some way to mute my microphones from a hotkey/shortcut, and if I can just find a program that can do, I will be set. As I said, I can also do a little bit if it is in C#, but the only code I have seen before for this, was miles long (atleast to me). My goal, is I just want a program that opens up, and toggles the mute on the microhpones (all of the system audio input) then closes. That is it, very simple. Thank you to anyone who trys to helps me! EDIT: Yes, I am using Windows. I am using Windows 7 32-bit. I already know that I can go into the volume mixer and do it that way, but I need to do this while running a full screen application, and it is a hassle to have to exit fullscreen, open the volume mixer, the click the mute icon, then go back into full screen and the the whole thing over again to unmute it. And I will be toggling back and forth quite often, so it just takes alot to do that so much.

  • Solaris 10 invalid ARP requests from 0.0.0.0? Link up/down every hour or 2

    - by JWD
    The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). [mymacaddress]/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) It's being logged every hour. I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. There are some tunable SCTP parameters but it's not something I'm familiar with. Do I have to add changes to /etc/system? Looks like sctp_heartbeat_interval might be what I need to change? If it makes any difference, I have a few solaris zones running on this server, each with their own IP address on a virtual interface. eth0:0, eth0:1, etc. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else? Update: This was happening more frequently but now it seems to be happening roughly every hour or every two hours. It's not consistent. I tried setting setting the link speed and duplex to match the switch port and that seemed to make it stop happening for a few hours but then it started again.

  • After adding a SSD to my MacBook, the HD never spins down.

    - by Chris Woods
    I added a SSD to my MacBook Pro 17 as the primary drive attached to the SATA controller. I moved the HD to the optical bay using the OptiBay from MCE Technologies which I use for my home directory. The problem I have encountered is the HD seems to never stop spinning. I have modified the sleep settings, hoping one of the various options would solve my problem without success. Any suggestions for me?

  • Why is a SUBST'd drive inaccessible via shortcut or Run menu, but works fine from My Computer?

    - by Kev
    I have shortcuts to C:, D:, and E: in my quick launch bar. C and E work fine when I click on them, but D does nothing (that I can see) when I click on it. D and E are both SUBST'd drives pointing to folders that happen to be network shares. (I do this rather than mapping them so it doesn't have to go through the network layer--that way it works faster and I still get recycle bin functionality, etc.) If I go Start-Run and type D: or D:\, I get an error box saying This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel. If I go to My Computer and double-click the D drive, it comes up fine. Also, if I type \\servername\sharename pointing to the same place, it comes up fine. This just started happening this morning, out of the blue. It has been working fine ever since I set it up. Why might this be?

  • BizTalk/MQ - DCOM was unable to communicate with the computer xxx using any of the configured protocols

    - by NealWalters
    I've read the other questions on this same error, but don't see a close match to this scenario. We got 18 of these last night between 12:17:13 and 12:39:37 on Win 2008/R2. It caused us to lose connectivity between BizTalk 2010 and WebSphere MQ machine. All our BizTalk machines (Prod, QA, Train, etc...) got the messages at the roughly same time and in the same quantity (about 18 of them). Computer xxx is the WebSphere MQ machine. What could cause this in the middle of the night? The servers are configured and running in Prod for a couple of years. There is no Win Firewall running, and servers are practically on the same rack. Could a run-away or 100% utilized CPU on the WebSphere MQ cause this issue? What else could cause it? BizTalk did NOT auto-recover from this situation. The above was followed by thousands of this message in the BizTalk event logs: The adapter "MQSeries" raised an error message. Details "Error encountered on Queue.Get Queue name = MyQManager/MyQueueName Reason code = 2354.". We restated BizTalk host instances, and it did not come back right away. It seemed we had to stop host instances for about two minutes, then start them.

  • How to find out what is causing a slow down of the application on this server?

    - by Jan P.
    This is not the typical serverfault question, but I'm out of ideas and don't know where else to go. If there are better places to ask this, just point me there in the comments. Thanks. Situation We have this web application that uses Zend Framework, so runs in PHP on an Apache web server. We use MySQL for data storage and memcached for object caching. The application has a very unique usage and load pattern. It is a mobile web application where every full hour a cronjob looks through the database for users that have some information waiting or action to do and sends this information to a (external) notification server, that pushes these notifications to them. After the users get these notifications, the go to the app and use it, mostly for a very short time. An hour later, same thing happens. Problem In the last few weeks usage of the application really started to grow. In the last few days we encountered very high load and doubling of application response times during and after the sending of these notifications (so basically every hour). The server doesn't crash or stop responding to requests, it just gets slower and slower and often takes 20 minutes to recover - until the same thing starts again at the full hour. We have extensive monitoring in place (New Relic, collectd) but I can't figure out what's wrong; I can't find the bottlekneck. That's where you come in: Can you help me figure out what's wrong and maybe how to fix it? Additional information The server is a 16 core Intel Xeon (8 cores with hyperthreading, I think) and 12GB RAM running Ubuntu 10.04 (Linux 3.2.4-20120307 x86_64). Apache is 2.2.x and PHP is Version 5.3.2-1ubuntu4.11. If any configuration information would help analyze the problem, just comment and I will add it. Graphs info phpinfo() apc status memcache status collectd Processes CPU Apache Load MySQL Vmem Disk New Relic Application performance Server overview Processes Network Disks (Sorry the graphs are gifs and not the same time period, but I think the most important info is in there)

  • Does Antivirus2009 or Antivirus360 automatically install on your computer and if so how?

    - by sergey
    I run Firefox on Vista, and unfortunately I got tricked (through a deceptive google result) into going to a page containing one of those fake "Your Computer Has all of this Spyware on it!" pages. I tried manually closing the tab, but it had a "Are you sure you want to navigate away" JavaScript alerts (HATE THOSE). So I clicked "OK," and the tab closed. Then I closed firefox altogether and rebooted. Now, before I could close the tab, it did prompt me to download a file, but of course I choose not to, and checking my downloads folder, nothing new is there. Also, even if I ?did? download it, ?I? would still have to choose to run it by double clicking on it for it to install itself, right? Also, I ran Malware Bites and Windows Defender and both said everything was fine. From this I would normally believe I am safe, but I have read everywhere that this thing "automatically installs" itself and that it is a bitch to get rid of. Is it really possible for this thing to dig in if you are running firefox and didn't choose to download it or run it after downloading?

  • How do I slow down a video generating new interpolated frames?

    - by Grzegorz Adam Hankiewicz
    I've used mencoder's speed parameter to generate a video which is played at half the speed. This basically means halving the framerate of the video. But I'm interested in software that could convert a 30fps video to another 30fps video with half the frames interpolated, maybe using the motion information stored in the video stream per se. I think this is called intra-frame interpolation, but I haven't found anything practical other than research papers. Any pointers to such software?

  • How can I shut down all my Virtual Machines when my UPS kicks in?

    - by Tim
    I have a Dell T610 running ESXi4, an APC Smart UPS 1000VA and a local "console" machine running Vista and the vSphere 4 Essentials pack. A dedicated management network is in place between the T610 and the Vista machine. We have 4 VMs: SBS 2003, Server 2003 running Terminal Services, and two XP Machines. Ideally, when the UPS is forced to use battery power [for a set number minutes], I would like to gracefully shutdown all the VMs, then the ESXi, then the console machine. The latter two are not strictly a priority, but the VMs within ESXi are. Google provided lots of deprecated scripts that used to work on ESXi 3.x or similar, however I am unable to find what they were deprecated by. What do I need to be able to do this? I have Powerchute Express as supplied with the UPS, but would be willing to pay for software if required.
