  • Is execution of sync(8) still required before shutting down linux?

    - by Amos Shapira
    I still see people recommend use of "sync; sync; sync; sleep 30; halt" incantations when talking about shutting down or rebooting Linux. I've been running Linux since its inception and although this was the recommended procedure in the BSD 4.2/4.3 and SunOS 4 days, I can't recall that I had to do that for at least the last ten years, during which I probably went through shutdown/reboot of Linux maybe thousands of times. I suspect that this is an anachronism since the days that the kernel couldn't unmount and sync the root filesystem and other critical filesystems required even during single-user mode (e.g. /tmp), and therefore it was necessary to tell it explicitly to flush as much data as it can to disk. These days, without finding the relevant code in the kernel source yet (digging through http://lxr.linux.no and google), I suspect that the kernel is smart enough to cleanly unmount even the root filesystem and the filesystem is smart enough to effectively do a sync(2) before unmounting itself during a normal "shutdown"/"reboot"/"poweorff". The "sync; sync; sync" is only necessary in extreme cases where the filesystem won't unmount cleanly (e.g. physical disk failure) or the system is in a state that only forcing a direct reboot(8) will get it out of its freeze (e.g. the load is too high to let it schedule the shutdown command). I also never do the "sync" procedure before unmounting removable devices, and never hit a problem. Another example - Xen allows the DomU to be sent a "shutdown" command from the Dom0, this is considered a "clean shutdown" without anyone having to login and type the magical "sync; sync; sync" first. Am I right or was I lucky for a few thousands of system shutdowns?

  • How to port VirtualBox machines with the recent snapshot?

    - by Liran Orevi
    I've ported a 'hard disk' using the 'clonehd' advice given on How to easily port VirtualBox machines? But it's not at the latest state, it's probably before any 'snapshot' was taken. I have only copied the 'hard disk', I haven't copied any 'snapshot' mainly because there are so many. I'm interested to transfer the 'hard disk' at it's latest state. How can this be done? (easily and not by coping the entire snapshots, machine etc...)

  • How can I use a DVI splitter cable on 1 DVI port?

    - by samoz
    I have a GTX 275 video card with 2 DVI ports. I already run 2 monitors, but I've seen cables that plug into one DVI port and split into 2 more connectors. Is there some special trick to getting this to work with my card so I could have up to 4 monitors running? I don't really want to buy the adapter until I know that it will work (or not work as it may be).

  • Using proxy server to redirect MySQL traffic to multiple servers using standard port?

    - by FrenchFry
    Is it possible to redirect MySQL (tcp) traffic to multiple servers based on domain name alone? Our DNS is setup to point several sub-domain aliases to one proxy machine. (running haproxy and iptables). We would like to redirect all database traffic through this proxy server and route it to the appropriate db server, WITHOUT deviating from the standard MySQL port. dev.domain1.com:3306 -- dbDevServer.domain1.com:3306 test.domain1.com:3306 -- dbTestServer.domain1.com:3306 prod.domain1.com:3306 -- dbProdServer.domain1.com:3306 Thanks!

  • How does a client find the port number of a server?

    - by Jonathan
    Hello all, I am currently learning about basic networking in java. I have been playing around with the server and client relationship between two of my computers. However, I cannot figure out how distributed programs (say, a videogame), can not only find the 'host' computer, but also the port number on which the server is running in order to create a Socket between the two computers. The only way I really see to create a Socket is with an already known IP Address, and with a known port number. How do you search a LAN network for another computer (host) searching for clients? How do you determine what port the server is located on without 'pinging' all available ports for a response (which, I understand, is bad form... Something about 'server attack'...)? In such a situation as a video game, there can be any number of computers on the same network, and any number of them might be attempting to host, or otherwise running the application. Any other important information, or perhaps reference to a more detailed tutorial than the one I am using, regarding making connections on so very little information on the client side would be appreciated. Many thanks, Jonathan

  • How can I obtain the local TCP port and IP Address of my client program?

    - by Dr Dork
    Hello! I'm prepping for a simple work project and am trying to familiarize myself with the basics of socket programming in a Unix dev environment. At this point, I have some basic server side code and client side code setup to communicate. Currently, my client code successfully connects to the server code and the server code sends it a test message, then both quit out. Perfect! That's exactly what I wanted to accomplish. Now I'm playing around with the functions used to obtain info about the two environments (server and client). I'd like to obtain the local IP address and dynamically assigned TCP port of the client. The function I've found to do this is getsockname()... //setup the socket if ((sockfd = socket(p->ai_family, p->ai_socktype, p->ai_protocol)) == -1) { perror("client: socket"); continue; } //Retrieve the locally-bound name of the specified socket and store it in the sockaddr structure sa_len = sizeof(sa); getsock_check = getsockname(sockfd,(struct sockaddr *)&sa,(socklen_t *)&sa_len) ; if (getsock_check== -1) { perror("getsockname"); exit(1); } printf("Local IP address is: %s\n", inet_ntoa(sa.sin_addr)); printf("Local port is: %d\n", (int) ntohs(sa.sin_port)); but the output is always zero... Local IP address is: 0.0.0.0 Local port is: 0 does anyone see anything I might be or am definitely doing wrong? Thanks so much in advance for all your help!

  • WiFi, No ping, other works fine

    - by Linux Mom
    I installed Ubuntu 12.04 LTS for my mom, this runs OK. However recently, I switched back and forth between encryptions on our WiFi Router from WPA-PSK to WEP and back again to WPA-PSK, same password. Now this old laptop won't even ping the gateway on the router, although the nm-applet shows connected. I tried re-adding the network and putting in the BSSID. I did this over again sometimes just to verify. I tried with my 3G Tethering on my phone, it works fine, can go online too. My other Linux laptop can go on the same wifi as well as my phone. And this laptop used to been online on the same network, same password, same encryption (WPA-PSK) What can be wrong ? Does it need a serious kick in the butt or removing some cached authorisation somewhere?

  • How do I correctly upgrade the kernel on Ubuntu 10.04 LTS?

    - by lal00
    I'm trying to upgrade the linux kernel from 2.6.32-34 to the latest update of that series, which appears to be 2.6.32-34. I ran: sudo apt-get update sudo apt-get upgrade At this point i was told that some packages were kept back: The following packages have been kept back: landscape-common linux-headers-server linux-image-server linux-server I proceeded to install those and then to autoremove the kernel (that's what apt-get recommended): sudo apt-get install linux-headers-server linux-image-server linux-server sudo apt-get autoremove My problem is that after booting, and running uname -a i still get the 2.6.32.34 kernel. How can I guarantee that the latest kernel will be loaded? thank you in advance.

  • Stream Music and Video Over the Internet with Windows Media Player 12

    - by DigitalGeekery
    A new feature in Windows Media Player 12, which is included with Windows 7, is being able to stream media over the web to other Windows 7 computers.  Today we will take a look at how to set it up and what you need to begin. Note: You will need to perform this process on each computer that you want to use. What You’ll Need Two computers running Windows 7 Home Premium, Professional, or Ultimate. The host, or home computer that you will be streaming the media from, cannot be on a public network or part of domain. Windows Live ID UPnP or Port Forwarding enabled on your home router Media files added to your Windows Media Player library Windows Live ID Sign up online for a Windows Live ID if you do not already have one. See the link below for a link to Windows Live.   Configuring the Windows 7 Computers Open Windows Media Player and go to the library section. Click on Stream and then “Allow Internet access to home media.”   The Internet Home Media Access pop up window will prompt you to link your Windows Live ID to a user account. Click “Link an online ID.” If you haven’t already installed the Windows Live ID Sign-In Assistant, you will be taken to Microsoft’s website and prompted to download it. Once you have completed the Windows Live download assistant install, you will see Windows Live ID online provider appear in the “Link Online IDs” window. Click on “Link Online ID.” Next, you’ll be prompted for a Windows Live ID and password. Enter your Windows Live ID and password and click “Sign In.” A pop up window will notify you that you have successfully allowed Internet access to home media. Now, you will have to repeat the exact same configuration on the 2nd Windows 7 computer. Once you have completed the same configuration on your 2nd computer, you might also need to configure your home router for port forwarding. If your router supports UPnP, you may not need to manually forward any ports on your router. So, this would be a good time to test your connection. Go to a nearby hotspot, or perhaps a neighbor’s house, and test to see if you can stream your media. If not, you’ll need to manually forward the ports. You can always choose to forward the ports anyway, just in case. Note: We tested on a Linksys WRT54GL router, which supports UPnP, and found we still needed to manually forward the ports. Finding the ports to forward on the router Open Windows Media Player and make sure you are in Library view. Click on “Stream” on the top menu, and select “Allow Internet access to home media.”   On the “Internet Home Media Access” window, click on “Diagnose connections.” The “Internet Streaming Diagnostic Tool” will pop up. Click on “Port forwarding information” near the bottom.   On the “Port Forwarding Information” window you will find both the Internal and External Port numbers you will need to forward on your router. The Internal port number should always be 10245. The external number will be different depending on your computer. Microsoft also recommends forwarding port 443. Configuring the Router Next, you’ll need to configure Port Forwarding on your home router. We will show you the steps for a Linksys WRT54GL router, however, the steps for port forwarding will vary from router to router. On the Linksys configuration page, click on the Administration Tab along the top, click the “Applications & Gaming Tab, and then the “Port Range Forward” tab below it. Under “Application,” type in a name. It can be any name you choose. In both the “Start” and “End” boxes, type the port number. Enter the IP address of your home computer in the IP address column. Click the check box under “Enable.” Do this for both the internal and external port numbers and port 443. When finished, click the “Save Settings” button. Note: It’s highly recommended that you configure your home computer with a static IP address When you’re ready to play your media over the Internet, open up Windows Media Player and look for your host computer and username listed under “Other Libraries.” Click on it expand the list to see your media libraries. Choose a library and a file to play. Now you can enjoy your streaming media over the Internet. Conclusion We found media streaming over the Internet to work fairly well. However, we did see a loss of quality with streaming video. Also, Recorded TV .wtv and dvr-ms files did not play at all. Check out our previous article to see how to stream media share and stream media between Windows 7 computers on your home network.
