  • Connecting with a BSNL Broadband Internet

    - by user10026
    I am not able to connect my broadband connection with ubuntu and it doesnt work. The connection works fine when I use Windows7 but when i use ubuntu I am not able to access the internet. I followed various steps mentioned in various sites and still could not find a solution. I have installed ubuntu 8.04 in my system. The interface eth0 is not at all detected and when i use the menu system-administrator-network I am not getting an option for wired connection. Just the Wireless connection and Point to Point connection tabs are available.. It's really urgent.. I'll be very happy if u guys can propose to me a working solution to deal with this problem..

  • Cannot access my own web page

    - by enflam3
    I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

  • Ubuntu Server - Virtual Box?

    - by user186144
    So I got VirtualBox just for Ubuntu Server, I'm currently Running Ubuntu 12.04 as my main OS. But when I got everything set up in Ubuntu Server 12.04, including my ports forwarded and a test Minecraft server up... I realized that nobody could join my public IP I sent out, not even me! I can connect to the ipv4 address. It acts like I didn't forward my ports. But I forwarded 25565 to Input and Output and they're both TCP and UDP. Is this just a virtual box issue or am I doing something wrong? * Using Eth0 wired connection

  • Microsoft Secret Event: New Tablet Unveiling?

    If you read the headline, you know what everyone thinks it will be: a new tablet computer, that Microsoft will manufacture from beginning to end. Apparently, the company believes it will be better able to compete against Apple if it controls both the hardware and the software. But why choose this location for the announcement? Wired thinks it makes sense if the tablet features Xbox live streaming. That would turn the humble device into something of a media machine. Speaking of the device itself, what kind of specs will this hypothetical tablet have? It's hard to say. Microsoft boasts software...

  • 14.04_x64 / Nvidia GT 240 , HUGE font notificaton at greeter and in naulitus after log-in

    - by mrlamud
    I've been using 12.04 for a long time - excellent version indeed, I decided to try 14.04 today. Installing without any problems. My VGA is Nvidia GT240 (legacy one), Nouveau display driver is fine, font display is normal. Then, I decided to install Nvidia legacy binary driver 304.117 updates (proprietary) instead of default Nouveau display driver. Problems come after rebooting At Greeter a notification "Wired connection 1 -Connected" pop up but with a HUGE font. After log-in HUGE FONT symptom still remains at some parts - for example, Calendar, Desktop shortcut and Files explorer. within few seconds, 10 to 15 may be, there is a screen blink but HUGE font still remains. I have to log out then log in again to have normal font in all parts of system. Changing driver, even an update one form ppa:xorg-edgersnot doesn't solve the problem. Any advices or solutions will be appreciated.

  • Wireless connectivity Wifi 7260 on Ubuntu 10.04

    - by user292332
    I am trying to install Wireless networking on Dell Latitude E5440 Wifi 7260- Ubuntu 10.04.(Yes I know it is old- see the complication below) I did get the wired connection working but our classrooms are wireless. I have tried to upgrade to version 12 last year but to my horror during the first week of class the nfs mounts did not work for multiple users. I never thought to test for more then one person at at time!! I have not been able to find a fix for the upgrade so I must remain at 10.04. NFS mounts are a must for student home directory access on the servers. All desktops are 10.04 as are the servers. Does anyone have a solution to the wireless problem in version 10.04/ or the nfs mounts solution in version 12. Thank you so much. Val

  • Ubuntu 12.04 wifi problem

    - by Akaash
    I'm having trouble with wifi on my MSI U180 netbook using Ubuntu 12.04. When I boot up the netbook, it will connect to my router however after a few minutes the wifi will just stop working and not find or connect to any networks. The only way to get wifi connectivity back is to reboot the netbook however the connection will again only last a few minutes. A wired connection works fine. I have tried connecting to a different router and the same thing happens. My friend has the same OS and netbook and his works fine. Does anybody have any possible solutions? Thanks in advance.

  • Java EE suitablity for a social network using Cassandra datastore ??

    - by Marcos
    We are in the process of making some important technology decisions for a social networking application. We're planning to have Cassandra(a NoSQL database to support efficient data storage). We would be using Hector(a Java client) to interact with Cassandra. 1.) Would Java EE be a good choice over PHP for a social networking application in terms of performance, scalabilty & complexities? 2.) Another possible implementation strategy, Is it suitable to have backend alone in Java and rest in PHP? 3.) What differences(as compared to PHP) it makes in terms of costs at various stages of application development, deployment and maintenance ? 4.) What are the things to keep in mind as we move along with Java development& deployment(as we are relatively new to the Java background) ? 5.) If you could list some major production deployments of similar type(social network) applications in Java. Thank you!

  • How to cast sockaddr_storage and avoid breaking strict-aliasing rules

    - by sinoth
    I'm using Beej's Guide to Networking and came across an aliasing issue. He proposes a function to return either the IPv4 or IPv6 address of a particular struct: 1 void *get_in_addr( struct sockaddr *sa ) 2 { 3 if (sa->sa_family == AF_INET) 4 return &(((struct sockaddr_in*)sa)->sin_addr); 5 else 6 return &(((struct sockaddr_in6*)sa)->sin6_addr); 7 } This causes GCC to spit out a strict-aliasing error for sa on line 3. As I understand it, it is because I call this function like so: struct sockaddr_storage their_addr; ... inet_ntop(their_addr.ss_family, get_in_addr((struct sockaddr *)&their_addr), connection_name, sizeof connection_name); I'm guessing the aliasing has to do with the fact that the their_addr variable is of type sockaddr_storage and another pointer of a differing type points to the same memory. Is the best way to get around this sticking sockaddr_storage, sockaddr_in, and sockaddr_in6 into a union? It seems like this should be well worn territory in networking, I just can't find any good examples with best practices. Also, if anyone can explain exactly where the aliasing issue takes place, I'd much appreciate it.

  • looking to streamline my RSS feed mashup

    - by Mark Cejas
    Hello crafty developers, I have aggregated RSS feeds from various sources with RSSowl, fetching directly from the social mention API. The RSS feeds are categorized into the following major categories: blogs, news, twitter, Q&A and social networking sites. Each major category is nested with a common group of RSS feeds that represent a particular client/brand ontology. Merging these feeds into the RSSowl reader application, allows me to conduct and save refined search queries (from the aggregated data) into a single file - that I can then tag and further segment for analysis. This scheme is utilized for my own research needs and has helped me considerably. However, I find this RSS mashup scheme kinda clumsy, it requires quite a bit of time to initially organize all of the feeds and I would like to be able to do further natural language processing to the data as well as eventually be able to rank the collected list of URL's into some order of media prominence - right I don't want to pay the ridiculous radian6 web analytics fees, when my intuition is telling me that with a bit of 'elbow grease' I can maybe leverage some available resources online to develop a functional low scale web mining application and get some good intelligence from it. I am now starting to learn a little about computer science - my background is in physical science/statistics so is my thinking in the right track? So, I guess I am imagining an application that allows me to query in a refined manner. A manner that allows me to search for keyword combinations, applying AND/OR operators, selectively focus my queries into particular sources - like a collection of blogs or twitter, or social networking communities, then save the results of my queries into a structured format that can then be manipulated and explored. Am I dreaming? I just had to get all of this out. any bit of advice and insight would be hugely appreciated. my best, Mark

  • Generic file container for quick read of data

    - by DreamCodeR
    Since there are some major privacy issues with alot of social networking sites I am trying to think about alternatives. One is to let the user keep all the information stored in some kind of file container. Now, I haven't found a single type of container that can hold "generic" information. Only for audio/video. What I want is a container that can be read by PHP with some kind of index file that lists up the users pictures in a image/ directory in the container, FOAF files (or some alternative XML-file describing users information and friends, etc.). My thoughts was to let the user keep all their information and data stored in a container that can be imported/exported and deleted from my server (the prototype social networking site I am trying to create), and then uploaded to another site that might use the same format (not that I think that will ever happen, but the user still keeps all their pictures, data, comments, messages, etc). The only thing I have come up with yet is to create a tar archive with the Archive_tar library which extracts and creates Tar-archives with an index-file describing which files are holding the messages (there might be several so each file won't be so large), what pictures are in the image/ folder and what are their names and what comments they have gotten etc. Maybe also the permissions for viewing each type of content. Does there exist any generic file format of a container that I can use to keep all this information in one file with a tree-like index file? Or must i try and create something like this myself?

  • How to allow local LAN access while connected to Cisco VPN?

    - by Ian Boyd
    How can I maintain local LAN access while connected to Cisco VPN? When connecting using Cisco VPN, the server has to ability to instruct the client to prevent local LAN access. Assuming this server-side option cannot be turned off, how can allow local LAN access while connected with a Cisco VPN client? I used to think it was simply a matter of routes being added that capture LAN traffic with a higher metric, for example: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.255.0.0 10.0.0.3 10.0.0.3 20 <--Local LAN 10.0.0.0 255.255.0.0 192.168.199.1 192.168.199.12 1 <--VPN Link And trying to delete the 10.0.x.x -> 192.168.199.12 route don't have any effect: >route delete 10.0.0.0 >route delete 10.0.0.0 mask 255.255.0.0 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 192.168.199.12 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 0x3 And while it still might simply be a routing issue, attempts to add or delete routes fail. At what level is Cisco VPN client driver doing what in the networking stack that takes overrides a local administrator's ability to administer their machine? The Cisco VPN client cannot be employing magic. It's still software running on my computer. What mechanism is it using to interfere with my machine's network? What happens when an IP/ICMP packet arrives on the network? Where in the networking stack is the packet getting eaten? See also No internet connection with Cisco VPN Cisco VPN Client interrupts connectivity to my LDAP server Cisco VPN stops Windows 7 Browsing How can I prohibit the creation of a route in Windows XP upon connection to Cisco VPN? Rerouting local LAN and Internet traffic when in VPN VPN Client "Allow local LAN Access" Allow Local LAN Access for VPN Clients on the VPN 3000 Concentrator Configuration Example LAN access gone when I connect to VPN Windows XP Documentation: Route Edit: Things I've not yet tried: >route delete 10.0.* Update: Since Cisco has abandoned their old client, in favor of AnyConnect (HTTP SSL based VPN), this question, unsolved, can be left as a relic of history. Going forward, we can try to solve the same problem with their new client.

  • openstack, bridging, netfilter and dnat

    - by Craig Sanders
    In a recent upgrade (from Openstack Diablo on Ubuntu Lucid to Openstack Essex on Ubuntu Precise), we found that DNS packets were frequently (almost always) dropped on the bridge interface (br100). For our compute-node hosts, that's a Mellanox MT26428 using the mlx4_en driver module. We've found two workarounds for this: Use an old lucid kernel (e.g. 2.6.32-41-generic). This causes other problems, in particular the lack of cgroups and the old version of the kvm and kvm_amd modules (we suspect the kvm module version is the source of a bug we're seeing where occasionally a VM will use 100% CPU). We've been running with this for the last few months, but can't stay here forever. With the newer Ubuntu Precise kernels (3.2.x), we've found that if we use sysctl to disable netfilter on bridge (see sysctl settings below) that DNS started working perfectly again. We thought this was the solution to our problem until we realised that turning off netfilter on the bridge interface will, of course, mean that the DNAT rule to redirect VM requests for the nova-api-metadata server (i.e. redirect packets destined for 169.254.169.254:80 to compute-node's-IP:8775) will be completely bypassed. Long-story short: with 3.x kernels, we can have reliable networking and broken metadata service or we can have broken networking and a metadata service that would work fine if there were any VMs to service. We haven't yet found a way to have both. Anyone seen this problem or anything like it before? got a fix? or a pointer in the right direction? Our suspicion is that it's specific to the Mellanox driver, but we're not sure of that (we've tried several different versions of the mlx4_en driver, starting with the version built-in to the 3.2.x kernels all the way up to the latest 1.5.8.3 driver from the mellanox web site. The mlx4_en driver in the 3.5.x kernel from Quantal doesn't work at all) BTW, our compute nodes have supermicro H8DGT motherboards with built-in mellanox NIC: 02:00.0 InfiniBand: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] (rev b0) we're not using the other two NICs in the system, only the Mellanox and the IPMI card are connected. Bridge netfilter sysctl settings: net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 Since discovering this bridge-nf sysctl workaround, we've found a few pages on the net recommending exactly this (including Openstack's latest network troubleshooting page and a launchpad bug report that linked to this blog-post that has a great description of the problem and the solution)....it's easier to find stuff when you know what to search for :), but we haven't found anything on the DNAT issue that it causes.

  • MVC2 Areas and Controller 404

    - by CodeGrue
    My project namespace is MyProject.MVC So my controllers, which are segregated into Areas, are in this namespace: MyProject.MVC.Areas.AreaName But when I try to access a controller action in this namespace, I get a 404 error: http://MySite/AreaName/Action/View If I "remove" the MVC portion from the namespace on my controllers, everything works correctly. MyProject.Areas.AreaName Could I have things wired incorrectly or is this an issues with MVC2 Areas?

    - by Sam Sanders
    I have a Cicso ASA 5510 that I want to connect to 2 Dell PowerConnect 5500 linked in a Switch Stack. I want to connect a trunking line to each switch so if one switch dies the other works. The problem is I can't seem to do anything thing with vlans on the 5510 using the "Cisco ASDM 6.4 for ASA" . Do I need to use CLI for this, or is it just not possible? I'm new at networking so any advice would be helpful.

  • Using Cisco VPN in Windows 7 XP Mode?

    - by Shane
    I previously asked a question about whether it was possible to use Cisco VPN client on Windows 7 64-bit (see below). Now that I have it set up, it doesn't work when I try to connect off the local network. I realize that there must be some networking/routing that I need to do since it's running on a virtual machine. How does one go about using the Cisco VPN client from XP mode in Windows 7? Related: Cisco VPN Client on Windows 7 64-bit?

  • Memcached Debuging/Server Logs Monitor the Memcached Servers?

    - by user1179459
    I have chat engine which is based on the Memcached variables, putting them into arrays and reading them in other end via jquery, which works fine 95% of the times, however when the server load is high memcached (presume its the memcached) the crash and browser gets stucks up. I dont think its jquery issue since this only happens when the server load is very high. I need a way to monitor the memcached servers or somehow write a log file into where the fails/errors comes in... Any idea on how i can do this ? or any idea why memcached servers fails ? I run the memcached as follows $GLOBALS['MemCached'] = FALSE; $GLOBALS['MemCached'] = new Memcache; $GLOBALS['MemCached']->pconnect('localhost', 11211); My memcached config is as follows #! /bin/sh # # chkconfig: - 55 45 # description: The memcached daemon is a network memory cache service. # processname: memcached # config: /etc/sysconfig/memcached # pidfile: /var/run/memcached/memcached.pid # Standard LSB functions #. /lib/lsb/init-functions # Source function library. . /etc/init.d/functions PORT=11211 USER=memcached MAXCONN=1024 CACHESIZE=128 OPTIONS="" if [ -f /etc/sysconfig/memcached ];then . /etc/sysconfig/memcached fi # Check that networking is up. . /etc/sysconfig/network if [ "$NETWORKING" = "no" ] then exit 0 fi RETVAL=0 prog="memcached" pidfile=${PIDFILE-/var/run/memcached/memcached.pid} lockfile=${LOCKFILE-/var/lock/subsys/memcached} start () { echo -n $"Starting $prog: " # Ensure that /var/run/memcached has proper permissions if [ "`stat -c %U /var/run/memcached`" != "$USER" ]; then chown $USER /var/run/memcached fi daemon --pidfile ${pidfile} memcached -d -p $PORT -u $USER -m $CACHESIZE -c $MAXCONN -P ${pidfile} $OPTIONS RETVAL=$? echo [ $RETVAL -eq 0 ] && touch ${lockfile} } stop () { echo -n $"Stopping $prog: " killproc -p ${pidfile} /usr/bin/memcached RETVAL=$? echo if [ $RETVAL -eq 0 ] ; then rm -f ${lockfile} ${pidfile} fi } restart () { stop start } # See how we were called. case "$1" in start) start ;; stop) stop ;; status) status -p ${pidfile} memcached RETVAL=$? ;; restart|reload|force-reload) restart ;; condrestart|try-restart) [ -f ${lockfile} ] && restart || : ;; *) echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart|try-restart}" RETVAL=2 ;; esac exit $RETVAL
