  • Ubuntu: Network connection seems to fail after some time

    - by chrischu
    I just bought a Shuttle XS-35 barebone mini-PC and put a 1 TB WD hard drive and 2 Gigs of RAM into it and installed Ubuntu onto it. The machine will post as a media server (streaming videos to my PS3) and as a webserver for some small private projects. Now I wanted to copy my videos from my Windows 7 machine to the Ubuntu machine and therefore created a Samba share on the Ubuntu machine. I tried copying the files with the standard Windows copy function and with SyncToy but after some time (sometimes 5 copied files, sometimes 120 copied files) the Samba share just disappears. When that happens I can't reach the internet from the Ubuntu machine although the network connection still seems to be fine (IP still there etc.). Between the machines lies a LinkSys router. When I try to ping my router (after the connection doesn't work anymore) from the Ubuntu machine only a very small subset of the packages actually get there (something around 20%). When I restart the Ubuntu machine everything seems to work normal again. I have no idea where the problem lies here. Does anybody have a clue? Thanks in advance!

  • Losing internet connection after few minutes (5-10 maybe)

    - by Korchkidu
    I took a computer that was not updated for months. Internet was working just fine so basically, I updated zonealarm, avast and installed all windows updates and especially SP3. After that, when I reboot, Internet works fine but after few minutes, Firefox says that the connection was reset. IE does not work either. However, my connection is still up and running as I can make a ping on www.google.com for example. Here are the solutions I tried with no success so far: 1) Uninstalling SP3; 2) Uninstalling IE8 and IE7; 3) Manually setting DNS and IPs; 4) Removed proxy settings from Firefox and IE; 5) Restarting DNS and DHCP related services; 6) Reset TCP/IP with netsh int ip reset c:\resetlog.txt; 7) Updated my ehternet card driver; 8) Restarted, tweaked all the connections in any directions and any configuration possible I believe; 9) Disabled Zone Alarm and Avast; Also, update kb981793 always fails on install. Please, help me as I spent two days already on this and I cannot find any solution. If I cannot fix this problem tomorrow, I will have to format-reinstall everything. Thanks for any help. Regards.

  • Using SSH, transfer webURL to remote machine

    - by AlanTuring
    Hi so i was doing some research in the library so i could use some pictures later on my Desktop computer in my room. I have space on my Lab account which i usually SSH into, and i was wondering if URL's can be directly transferred over to a remote machine and saved on the hard disk. I was thinking something like this: scp http://click.si.edu/images/truncatedurl.jpg /home3/etc.../filename.jpg is this possible? Thanks in advance.

  • Nginx: Loopback connection via PHP's getimage size crashes server (Magento's CMS)

    - by Alex
    We were able to trace down a problem that is crashing our NGINX server running Magento until the following point: Background info: Magento Backend has a CMS function with a WYSIWYG editor. This editor loads some pictures via a controller in magento (cms/directive). When we set the NGINX error_log level to info, we get the following lines (line break inserted for better readability): 2012/10/22 18:05:40 [info] 14105#0: *1 client closed prematurely connection, so upstream connection is closed too while sending request to upstream, client: XXXXXXXXX, server: test.local, request: "GET index.php/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL,,/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9024", host: "test.local" When checking the code in the debugger, the following call does never return (in ´Varien_Image_Adapter_Abstract::getMimeType()` # $this->_fileName is http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif` # $_SERVER['REQUEST_URI'] = http://test.local/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL list($this->_imageSrcWidth, $this->_imageSrcHeight, $this->_fileType, ) = getimagesize($this->_fileName); The filename requests is an URL to the same server which is requesting the script a link to a static .gif that is not existing. Sample URL: http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif When the above line executed, any subsequent request to the NGNIX server does not respond any more. After waiting for around 10 minutes, the NGINX server starts answering requests again. I tried to reproduce the error with a simple test script that only calls getimagesize() with the given URL - but this not crash. It simple leads to an exception saying that the URL could not be loaded (which is fine as the URL is wrong)

  • Setup shared internet connection on virtualbox with fixed IP

    - by Tom
    I am a web developer and until recently I have been using ubuntu as my OS. For many reasons, I have switched back to windows. I still want to keep my server on linux platform, so I setup my local server as a virtual machine. Everything works great, but i have a little struggle with the networking. Since I am working in different places and going around clients, I connect to all sorts of network with different settings. That means the possible IP range is very dynamic which causes issues when I work on my local server. At the moment I have a dynamic IP on my host and static IP on my guest. That way I can access the server from my host (by adding record to hosts file). I also have internet connection on the guest. But once i change networks, it does not work (assuming the network has different configuration). My question is, how to setup host-guest networking, so no matter what network I connect to, I can keep my static IP on guest, which is registered in hosts file on my host so I can access the webserver and also I will have internet connection on the guest? Hope it make sense. Thank you

  • Connecte RemoteApp to Exising Session

    - by Fowl
    Due to the slightly retardedness of an app I've got to run, I've got a server auto logging in on boot with the app on auto start. Remote desktop at my leisure to check on its status, etc. Gross, but it works. Now I've tried out RemoteApp which seems to work ok (ie. remotes the notification icon, balloons...) except for the fact that it creates a new session (and therefore instance of my app) - this confuses the heck out of app and it means that if I was using 'full' remote desktop I lose all my state. "Restrict each user to a single session" doesn't work. IIRC "Windows XP Mode" uses RemoteApp and it doesn't seem to have any trouble switching between modes. So how can I connect to a running app?

  • troubleshooting postifx -> exchange connection issues

    - by Systemspoet
    I have three linux-based mail routers that run postfix and relay mail to our on-premise exchange server as well as to outlook.com, splitting the mail based on ldap atttributes. What I've observed sporadically since upgrading this spring from Exchange 2007 to 2010 is that all three of the mail relays will, for about 20 minutes, fail to connect to exchange. Postfix logs it as "lost connection with exchange.contosso.edu" ; this problem almost always occurs to all three mail relays at the same time, and lasts for slightly under 20 minutes. If I can catch it while it's occuring, and I manually do "telnet exchange.contosso.edu 25" from one mail relay and force a message through (helo, mail from, rcpt to, data, etc), then it clears that relay up. The exchange "server" is actually two machines with the HT role on them, load balanced via windows NLB. I've worked pretty hard to figure out what's happening from the postfix side and I can't see any evidence of any misbehavior. My question is, how do I attack the problem from the exchange side? Is there a connection log, or a debug setting, or something I can do to log all of the inbound connections and tell me what's causing exchange to drop them?

  • Getting started with VNC

    - by Stephen
    I have subscribed to a VPS service for the purpose of running some remote applications. To do this I'm going to need a remote desktop of one sort or another. With this in mind it was suggested that I try Ubuntu. The installation that was prepared for me was Ubuntu 11.10 64 bit (Ubuntu 11.10 (GNU/Linux 2.6.18-348.4.1.el5.028stab107.1 x86_64)) From here I used apt-get install ubuntu-desktop which completed successfully. I rebooted the machine and reconnected via ssh. When I attempt to connect from TightVNC on my Windows machine I get a message about the session being actively refused. What should I do to confirm the service is running? Do I need to setup a firewall rule to allow the ports to pass through? (I am a linux newb so explicitness is appreciated)

  • Remote access to server via service control panel for non-admin user in Windows 2008

    - by user2278
    I'm trying to configure my Windows 2008 servers so that my developers can view their status without needing to log on to the box or be an admin. Unfortunately, the permissions set in Windows 2008 for remote non-admin users don't include the ability to enumerate or otherwise query services. This causes anything that contacts the SCM on the far end to fail (Win32_Service, sc.exe, services.msc etc). How do I set up permissions so that they can at least list the services and see if they are running?

  • Real time audio streaming

    - by Josh K
    I have a remote computer running OS X. I would like to stream the audio from the microphone input over the network so I can listen to it. Primarily I want to do this because I'm out of the office but still need to communicate with people there. I would like to use VLC, but am not fully aware of the options available. I tried SoundFly (as recommended by another answer) but this didn't seem to want to connect. At this point I should note that I'm using a VPN network to connect to the remote computer (using Hamachi). I can open up ports / etc fine though, so I should be able to do this. Alright, I found Nicecase which does exactly what I want but I would prefer to not have to shell out $40 for it.

  • How do you permanently disable the 'This Connection is Untrusted' page on Firefox

    - by TheIronChef9
    I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

  • 2 workstations won't connect to most websites, but will connect to some

    - by Dean
    I have a very frustrating issue I wasn't able to solve: 2 workstations which are used by the same user are not able to connect to most websites receivin a timeout, however they will load some websites specificly from my country. They are able to get the website addresses via DNS. Both stations have their internet connection through a remote router. Other stations in the same LAN are connecting fine. Here's what I tried: Virus scan Renewing IPs Reseting the workstations Moving one workstation to a different RJ-45 in the wall Reseting the hub and switch Checking the hosts file DNS flush Nothing seems to help. I am preparing a CD with more AV tools to see if there's anything hiding on the stations. UPDATE: It was an incorrect configuration in "Internet Options". I configured the correct proxy and now it works.

  • Security camera for HQ and remote sites?

    - by Atlas
    We want to install security cams at HQ site and 3 remotes sites. Basically: (1) Each site would have N cams (2) Each site should have DVR locally to record everything. What we want is that HQ to be able to see the live/recorded videos of each remote site and including itself. Preferably HQ would have 1 large screen, and display all cams of itself and remotes sites, say showing it in 32x32 cells. Does such system exists?

  • Windows 7 RDP Fullscreen mode

    - by kubal5003
    I have a problem with remote desktop connection in Windows 7. When I connect to remote computer I would like to switch to fullscreen like I did in previous versions - just by clicking maximize. When I was in fullscreen mode and I moved the mouse to the upper border of the screen a nice bar appeared and I could minimize rdp or close it. In Windows seven when I click on the maximize button the window maximizes like a normal window - menu start/taskbar(whatever you call it) is still visible and because the resolution of the rdp client desktop is set like on the computer that I'm using it's not fully visible and scrollbars appear. That's really annoying. Can anyone tell me what to do? Is it a bug or maybe there is a "magic shortcut" that is poorly documented and does the trick? (I was trying to find it myself first ofcoz, but no result)

  • rsync delete remote duplicates

    - by BlakBat
    I'm trying to delete remote duplicate files without transferring the non-existing files, and without updating the existing files. If I specify both --existing and --ignore-existing (along with "-av --remove-source-files", the operation is a no-op and nothing will be transfered, but nothing will be deleted either. The best I got so far is to make a local copy of destination, use rsync without --ignore-existing, then rsync my local copy on top of the destination

  • Monitor Windows Terminal Sessions from Linux/Mac

    - by mhd
    I'm writing some scripts to make remote connections to a Windows 2003 server a bit more user-friendly, and in doing this I want to see who's logged in already. In Windows, I could use qwinsta.exe to do this, even for remote servers. So it is exposed somehow, but I couldn't find a matching command line tool for Unix. Lacking such a tool, I could install an ssh server on the machine and call it remotely, parsing the output or write a small service of my own that would expose this via http, if I don't want full-blown ssh access. Do I have to do this, or is there already a tool for querying terminal services remotely?

  • Mesh Remote Desktop crashes 64 bit Windows 7 VM (8 GB)

    - by Andrew J. Brehm
    I have a Windows 7 VirtualBox VM (64 bit, 8 GB) on a Snow Leopard host (64 bit, 24 GB). It works fine until I connect via Microsoft Mesh. When I connect via Mesh remote desktop, the VM crashes about one or two minutes after the connection has been established. It doesn't answer to pings (from the host and from other machines in the network) and no RDC connections (from other Windows machines in the network where Mesh works) are possible. Any ideas?

  • IIS 6.0 https not working "connection was reset"

    - by cad
    Application Server Windows Server 2003 SP2 with IIS 6.0 IIS has a "Default Web Site" (port 18000, ssl 443, ID=1) with a certificate created by me. I have an specific site called "scj.galaxy.Weekly" (port 80, ssl 443, ID=1272369728) that is working fine. I have an entry in windows/system32/drivers/etc/hosts that links galaxy.Weekly.scjdev.ds to the server ip in both my local machine and in the application Server. These sites works: http://scj.galaxy.weekly/test.html works http://scj.galaxy.weekly/test.aspx works But https://scj.galaxy.weekly/test.html fails Error message is: The connection was reset The connection to the server was reset while the page was loading. The certificate was working fine for months. It was created with something similar to this: Selfssl /N:CN=*.scjdev.ds /V:3650 /S:1 /P:443 I have tried several options and none of them are working: 1) Create a certificate only in "Default Web Site" and link it to SecureBindings with command prompt cscript adsutil.vbs set /w3svc/1272369728/SecureBindings ":443:galaxy.Weekly.scjdev.ds" 2) Create a certificate only in "Galaxy Site" and link it to SecureBindings 3) Create a certificate in both and link them to secureBindings. Probably I am missing an step or something, but I can't see it. Here is the relevant config of Galaxy Site: <IIsWebServer Location ="/LM/W3SVC/1272369729" AuthFlags="0" LogPluginClsid="{FF160663-DE82-11CF-BC0A-00AA006111E0}" SSLCertHash="c36a514a0be90fbc121d9c19bb052842289d5aee" SSLStoreName="MY" SecureBindings=":443:galaxy.Weekly.scjdev.ds" ServerAutoStart="TRUE" ServerBindings=":80:galaxy.Weekly.scjdev.ds" ServerComment="galaxy.Weekly.scjdev.ds" > </IIsWebServer> <IIsWebVirtualDir Location ="/LM/W3SVC/1272369729/root" AccessFlags="AccessRead | AccessScript" AppFriendlyName="Default Application" AppIsolated="2" AppRoot="/LM/W3SVC/1272369729/Root" AuthFlags="AuthAnonymous | AuthNTLM" DefaultDoc="Default.aspx" DirBrowseFlags="EnableDirBrowsing | DirBrowseShowDate | DirBrowseShowTime | DirBrowseShowSize | DirBrowseShowExtension | DirBrowseShowLongDate" Path="D:\Webs\Galaxysite" ScriptMaps="some config...

  • Shares not working on boot need to reinstall "File and Printer Sharing for Microsoft Networks" on server every morning to fix

    - by Neaox
    I had a problem a few days ago see question here: Can no longer access computer or network shares to my server from any other computers on the network The fix that I found does in fact work however when I boot my PC in the morning the shares are no longer working, to fix this I need to remote desktop into the server and re-install "File and Printer Sharing for Microsoft Networks" on the main adaptor. Doing this makes the shares work again, however it is anoying to have to do this each and every morning. On top of this my offline files are no longer available offline: I store my user profile on the server and had them selected to be "Always Available" however since this has happened they are no longer available offline and the option to make them available offline from the context menu is no longer available. Another problem, and I don't know if this is the cause or just a tell of a deeper issue but this server runs hyper-v, since these problems I can no longer remote desktop into the hyper-v client. Thanks for any help anyone can give.

  • Seeing double-cursor in 'recursive RDP'

    - by John
    I'm using a Virtual PC VM on my PC to connect to a remote PC using RDP over a VPN. It works just fine except that in the RDP session, I often see a double mouse cursor... I get a standard mouse-arrow and the context-specific cursor such as a caret or hourglass. It's not a big problem but rather annoying and I wondered if there's any way to fix it, or at least understand where it comes from? Is it because I'm effectively running one RDP session from inside another? My host PC runs W7, my local VM runs XP, and the remote PC access using RDP is W7. Thankyou for any help.

  • Using cssh with an ssh clone

    - by decimus phostle
    Just had a quick question about using ClusterSSH(cssh) with a homegrown ssh-like/ssh-clone application which we use internally to connect to remote machines. I tried using the ssh = /path/to/ssh_clone override in $HOME/.csshrc or /etc/csshrc (or even passing it via -C). Unfortunately running cssh with debug shows that it is still trying to connect to the remote machines as ssh -l user machine_ip instead of ssh_clone -l user machine_ip. Any thoughts/suggestions on how to work around this would be greatly appreciated. TIA. Edit: Version info $ cssh -v Version: 4.01_02
