  • How to get Visual Studio 2010 Express Edition on Windows 7

    - by thanigai
    Visual studio 2010 is an amzing release from Microsoft. I have tried the beta 1,2 of Visual Studio 2010 and finally the full version is released. I am also interested in the latest edition of Windows which nothing but our Windows 7. Next to Vista I like this version very much. Out of curiosity I have installed the prebuild version of Windows 7. I tried installing the express edition here and it failed making me disappointed. I tried two or three times and finally I decided to download the trial version of Windows 7. After that I can install the Visual Studio 2010 express edition easily. I have given the link below from where I have downloaded the file. http://www.microsoft.com/express/downloads/ Here the link give is through Web PI Installer. Other option is you can download the ISO image file and burn them to a disc or use a virtual disc This Visual Web developer will provide the Sql Server engine alone. To get a Sql Server Management Studio get from the following link http://www.microsoft.com/express/Database/InstallOptions.aspx That's it all the things necessary for the web application programming is ready. Ah I forget to tell about the Silverlight. Please find the Silverlight 4 latest tools from the below link (WCF RIA services is the main update) http://www.silverlight.net/getstarted/ Silverlight 4 Tools(http://www.microsoft.com/downloads/details.aspx?FamilyID=eff8a0da-0a4d-48e8-8366-6ddf2ecad801&displaylang=en) Expression Blend 4 trial(http://www.microsoft.com/downloads/details.aspx?FamilyID=88484825-1b3c-4e8c-8b14-b05d025e1541&displaylang=en) I think the reader would have enjoyed on how to get these things. Please let me know if you are not clear with any of these things.  Thanks, Thani

  • Wireless will not connect on an Asus U56? [closed]

    - by ernie
    I have an ASUS U56. I could connect to internet without delay or problems in Ubuntu 11.04. Now, running Ubuntu 11.10, I have not been able to connect. I can see the network and the computer tries to connect, but never makes the connection. I have been trying to fix this problem since the release date of 11.10. I had to install the older kernel 2.6 to get the wifi to work. Any other solutions? ernest@ernest-U56E:~$ ifconfig eth0 Link encap:Ethernet HWaddr 14:da:e9:25:6c:d0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:53 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wlan0 Link encap:Ethernet HWaddr 40:25:c2:3f:46:d4 inet addr:192.168.xx.xxx Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::4225:c2ff:fe3f:46d4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:44962 errors:0 dropped:0 overruns:0 frame:0 TX packets:32287 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:35614976 (35.6 MB) TX bytes:5400816 (5.4 MB) ernest@ernest-U56E:~$

  • Why does my Intel Tolapai network chip not transmit packets?

    - by Hanno Fietz
    I'm trying to deploy an embedded system (NISE 110 by Nexcom) based on the Intel EP80579 (Tolapai) chip. Tolapai apparently integrates controllers for Ethernet etc. on a single chip (Intel homepage). The machine can't get a network connection. Diagnosis as far as I could manage: Drivers drivers from Intel compiled and installed without problems (version 1.0.3-144). Kernel version and Linux distribution (CentOS 5.2, 2.6.18) match the driver's installation instructions. drivers are loaded and show up in lsmod (module names are gcu and iegbe) interfaces eth0 and eth1 show up in ifconfig ifconfig I can bring up the interfaces with fixed IP pinging the interface locally works ifconfig shows flag UP but not RUNNING Link ethtool shows "Link detected: no", "Speed: unknown (65536)" and "Duplex: unknown (255)" Link LED is on on the other side of the cable, ethtool shows "Link detected: yes" and reports a speed of 1000 Mbps, which has allegedly been auto-neogotiated with the problematic device. Network traffic analysis the device does not reply on ARP, ICMP echo or anything else (iptables is down) when trying to send ICMP or DHCP requests, they never reach the other end activity LED is off on the device, on at the other end. I tried the following without any effect: Different cables (2 straight, one crossed), I get the link LED lit up on each. Three different devices on the other end (one PC, one netbook, one router) Fixed ARP table entries on both sides Connecting both network ports of the machine with each other, won't ping through the cable, but will ping locally. Tried straight and crossed cables for that.

  • Can I ping via an arbitrary interface of a DD-WRT system?

    - by bytebuster
    There's a Linksys WRT54GL router with DD-WRT firmware (v23SP2). The network has a simple dual-WAN configuration (standby mode, switching by a script): ~ # ip route 192.168.3.0/24 dev br0 proto kernel scope link src 192.168.3.1 192.168.2.0/24 dev vlan2 proto kernel scope link src 192.168.2.2 192.168.1.0/24 dev vlan1 proto kernel scope link src 192.168.1.67 127.0.0.0/8 dev lo scope link default via 192.168.2.1 dev vlan2 I'm trying to ping a certain server arbitrary via vlan1 or vlan2. What I tried, as suggested here: ping -I vlan2 <address> ping 192.168.2.1 <address> In both cases ping simply exits with no error messages. Also, ping ignores many other parameters, again, by exiting silently. I failed to find any references that DD-WRT has a limited version of ping whatsoever. I also don't think it can be a permissions issue as mentioned here since the only user with DD-WRT is root. What's wrong?

  • There's IP but can't reach gateway

    - by icky
    I have just installed ubuntu 12.04 on my new laptop, and brought it back to home, but I found the wireless network does not work. Strangely, it has the correct ip, but can't connect to the gateway. ifconfig gives ip 192.168.64.36, with broadcast 192.168.79.255 and mask 255.255.240.0, this are all correct, the gateway is at 192.168.64.1 cat /etc/resolv.conf nameserver 192.168.64.1 nameserver 127.0.0.1 which i think it's also right. but when I ping 192.168.64.1, all packages are lost. Please help me with this, I really do not know what happened to my network settings. Huckle, Thank you for your reply ifconfig wlan0 Link encap:Ethernet Hwaddr 88:f9:af:2a:ca:1b inet addr:192.168.64.36 Bcast:192.168.79.255 Mask:255.255.240.0 inet6 addr: fe80::8a9f:faff:fea2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:27 errors:0 dropped:0 overruns:0 frame:0 TX packets:376 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3950 TX byetes:60288 iwconfig wlan0 IEEE 802.11bgn ESSID:"Chiono" Mode:Managed Frequency:2.417 GHz Access Point: 82:54:99:94:6D:43 Bit Rate=13.5 Mb/s Tx-Power=13 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=70/70 Signal Level=-32 dBm Rx invalid nwid:0 Rx invalid crypt:0 RX invalid frag:0 Tx excessive retries: 9 Invalid misc:10 Missed beacon:0 route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.64.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.64.0 * 255.255.240.0 U 2 0 0 0 wlan0 Thank you very much

  • "Always available offline" option missing on one network drive in Windows 7

    - by Rynardt
    My network setup at home has 2 network storage devices on the network. The one is for media content on a Popcorn Hour A-110 and the other is a D-Link DNS-320 in RAID 1 configuration for business files. When I access these network drives and right click a folder the following context menu appears for the A-110 device, but not for the D-link. I have tested this in both Windows 7 32bit and Windows Vista 64bit. In both instances the "Always available offline" option is only available for the A-110 storage device, and not for the D-link. How do I get this option for the D-link? Any advice or ideas are welcome.

  • Perl script rendered in browser as code through symlink - fine when accessed directly

    - by John Dittmar
    I have a Rails 4 app that has some views that post to Perl cgi scripts. The perl scripts are accessed via a symbolic link to a folder called "cgi-bin". When I navigate to a perl script through the symbolic link they are rendered as text instead of executed (ie: localhost:3000/cgi-bin/test.cgi), however when I access them directly they execute without issue (ie. localhost/path/to/cgi-bin/test.cgi). I am using apache2 on os x. In the directory localhost/path/to/ I have an .htaccess file that contains the following: # General Apache options AddHandler fastcgi-script .fcgi AddHandler cgi-script .cgi Options +FollowSymLinks +ExecCGI I have the exact same lines in the .htaccess file that I have in localhost:3000/ I have also uncommented the AllowOverride all in httpd.conf. The are no errors in apache's error log. When I access the direct link to test.cgi a new line is appended to apache's access log, when I access the script through the symbolic link (and it is rendered as text), there is no line appended to the access log. Any idea why this error occurs? This setup worked fine in a previous version of rails of OS X, but recently I upgraded to Mavericks and figured I should update the Rails application to v4.0 as well.

  • On wordpress.com how to set a category as front page?

    - by Shashank Sawant
    I first referred to a link explaining how to set a page as your front page. What I want is to set a category of my blogs as my front page display. Hoping for an answer, I went to the following link: http://en.forums.wordpress.com/topic/1-category-as-front-page?replies=4 It effectively redirects me to my first link. Though I can make a page on wordpress.com and set it as my front page, I still haven't understood how to set one of my blog categories as my front display.

  • Windows Azure AppFabric SDK - June CTP - Download issues

    - by Charles Young
    Microsoft has announced availability of the June CTP for Windows Azure AppFabric. See http://blogs.msdn.com/b/appfabric/archive/2011/06/20/announcing-the-windows-azure-appfabric-june-ctp.aspx. This is an exciting release and provides greater insight into where the AppFabric team is heading in terms of developer and management tooling. Microsoft is offering space in the cloud to experiment with the CTP, but this is limited, so register early to get a namespace! You can download the SDK for the June CTP. However, we ran into a lot of trouble trying to do this today. Whenever we followed the link, we ended up on the page for the May CTP. We found what appeared to be a workaround which we were able to repeat on another box (and which I reported on Connect), but then a few minutes later I couldn't repeat it. Just now, the given link appears to be working every time in IE, but not in Firefox!   Frankly, the behaviour seems random!   It looks like the same URL points to two different pages, and I suspect that which page you end up on is hit and miss. The link to the download page is http://www.microsoft.com/download/en/details.aspx?id=17691. If you end up on the wrong page, try again later and you may get to the right place. Or try googling "Windows Azure AppFabric SDK CTP – June Update" and following a link to this page. For some reason, that sometimes seems to work. Good luck!

  • Windows doesn't get access to internet though linux easily does

    - by flashnik
    We have a very interesting problem. The network is configured in this way: internet is connected to Trendnet switch TS DHCP server at 192.168.0.1 running on Ubuntu (S) is connected to internet switch DNS is also configured on 192.168.0.1 on S D-Link Wi-Fi boosters are connected to switch TS PCs use D-Link PCI-E Wi-Fi cards to get access to network PCs have both Ubuntu and Windows 7 There are about 40 PCs. When PC is booted to Ubuntu it easily gets access to internet. But when it's booted to Windows 7, it gets a valid IP-address, but doesn't get access to internet. The address, mask, DNS, GW-address are totally the same as when it's booted under Ubuntu. The S is reacheble and pingable. Sometimes when we are lucky the PC gets access to Internet, but after rebooting it can lose it. When PC under Windows has access, it has totally the same settings as when it doesn't. What can be done? UPDATE I shared a dropbox with 2 captures of traffic. Ping.pcap is a capture of pinging 8.8.8.8. And google-browser.pcap is a capture of opening a google.com in a browser, both of them are in tcpdump formats and made by Wireshark on Win PC. The MAC of Win PC ends on b7:63 and IP is 192.168.0.130.

  • Bluetooth mouse no longer paired after resuming from suspend since upgrading to 13.10

    - by Korakys
    Since upgrading to 13.10 from 13.04 my mouse no longer connects via bluetooth. In settings it states that the mouse is not paired. Restarting bluetooth with sudo /etc/init.d/bluetooth restart does not help. Restarting the computer does fix the problem if bluetooth is restarted also with the previously mentioned command, but this is not ideal. The mouse worked fine prior to updating to 13.10. The computer is a ThinkPad X230 with a Broadcom 'BCM20702A0' bluetooth module (I think). When it is not working hciconfig hci0 -a returns: hci0: Type: BR/EDR Bus: USB BD Address: C0:18:85:DB:F3:D1 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING PSCAN RX bytes:766129 acl:49888 sco:0 events:2233 errors:0 TX bytes:5953 acl:240 sco:0 commands:274 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'BCM20702A' Class: 0x6e0100 Service Classes: Networking, Rendering, Capturing, Audio, Telephony Device Class: Computer, Uncategorized HCI Version: 4.0 (0x6) Revision: 0x1000 LMP Version: 4.0 (0x6) Subversion: 0x220e Manufacturer: Broadcom Corporation (15) When it is working hciconfig hci0 -a returns: hci0: Type: BR/EDR Bus: USB BD Address: C0:18:85:DB:F3:D1 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING PSCAN RX bytes:253334 acl:16391 sco:0 events:842 errors:0 TX bytes:2519 acl:65 sco:0 commands:84 errors:0 Features: 0xbf 0xfe 0xcf 0xfe 0xdb 0xff 0x7b 0x87 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH SNIFF Link mode: SLAVE ACCEPT Name: 'ubuntu-0' Class: 0x6e0100 Service Classes: Networking, Rendering, Capturing, Audio, Telephony Device Class: Computer, Uncategorized HCI Version: 4.0 (0x6) Revision: 0x1000 LMP Version: 4.0 (0x6) Subversion: 0x220e Manufacturer: Broadcom Corporation (15) I am a relative novice with linux so don't ask me compile anything please, but I can use google.

  • Can I ping via an arbitrary interface of a DD-WRT system? [migrated]

    - by bytebuster
    There's a Linksys WRT54GL router with DD-WRT firmware (v23SP2). The network has a simple dual-WAN configuration (standby mode, switching by a script): ~ # ip route 192.168.3.0/24 dev br0 proto kernel scope link src 192.168.3.1 192.168.2.0/24 dev vlan2 proto kernel scope link src 192.168.2.2 192.168.1.0/24 dev vlan1 proto kernel scope link src 192.168.1.67 127.0.0.0/8 dev lo scope link default via 192.168.2.1 dev vlan2 I'm trying to ping a certain server arbitrary via vlan1 or vlan2. What I tried, as suggested here: ping -I vlan2 <address> ping 192.168.2.1 <address> In both cases ping simply exits with no error messages. Also, ping ignores many other parameters, again, by exiting silently. I failed to find any references that DD-WRT has a limited version of ping whatsoever. I also don't think it can be a permissions issue as mentioned here since the only user with DD-WRT is root. What's wrong?

  • arp "who-has tell" on cloned machine

    - by mcmorry
    I have a urgent problem to solve today, but I'm lost. Please help. I've cloned a Virtual Machine hosted on VM Ware ESXi 4.1 The OS is now Ubuntu Server 12.04 LTS, but at the time of cloning it was 10.04 LTS. I fixed the MAC address manually inside /etc/udev/rules.d/70-persistent-net.rules. It is a known problem on Ubuntu. I had to remove the old MAC address and set the new one as eth0. Everything seems to work fine, except ARP. My provider OVH sent me a warning to resolve it today (this is the second day) or they will block my IP! The log contains many lines like this: Tue Jun 5 01:04:29 2012 : arp who-has 178.32.136.212 tell 178.32.136.224 where .224 is the cloned server that is causing problems, and .212 is the cloned one. arp -na returns: ?

I'm not an expert and I don't know what else to do to fix this problem. Any help will be very appreciated. Thanks.

  • Is it possible to use Google Docs Viewer to view files already in Google Docs?

    - by john2x
    The title is a little confusing. I'll elaborate. As far as I can tell, the Google Docs Viewer tool accepts a link to a raw document file (e.g. .doc, .pdf, et. al.), and renders its contents in the browser. For example, this url to a pdf http://research.google.com/archive/bigtable-osdi06.pdf when passed to Viewer, returns this link: http://docs.google.com/viewer?url=http%3A%2F%2Fresearch.google.com%2Farchive%2Fbigtable-osdi06.pdf What I'm trying to achieve is, use the Viewer to view a document already hosted in Google Docs (i.e. no longer a raw document file). When passing a link to a Google Docs document to the Viewer, the result is not as expected. It renders the link's HTML source instead of the document's contents. The reason I want to do this is that I want to be able to use the "embed" feature of Viewer to view Google Docs documents. Does Google Docs have a "link to embeddable view" feature? P.S. Here is a sample snippet to an embedded document. This is what I want, but pointing to an existing Google Docs document. <iframe src="http://docs.google.com/viewer?url=http%3A%2F%2Fresearch.google.com%2Farchive%2Fbigtable-osdi06.pdf&embedded=true" width="600" height="780" style="border: none;"></iframe>

  • Maximise network transfer speed of various applications

    - by Alex
    When using nc, scp, wget to transfer files between 2 machines on a dedicated 2Mbps link, I get speeds between 0.5 and 1 Mbps. However, when I use iperf -c 10.0.1.4 -t 20 -P 12 (for example) I can maximise the speed of the link (getting stable 2Mbps). Is there a way to make single stream transfers (such as those done by scp) to utilise all/most of the link? Some kind of tcp settings, or iptables...?

  • Macvlan based interface pings from host but not from namespace

    - by jtlebi
    My setup: Private network vboxnet1 10.0.7.0/24 1 Host, ubuntu desktop 1 VM, ubuntu server (VirtualBox) Adressing layout: HOST: 10.0.7.1 VM: 10.0.7.101 VM MAC NAMESPACE: 10.0.7.102 On the VM, I ran the following commands: ip netns add mac # create a new nmespace ip link add link eth0 mac0 type macvlan # create a new macvlan interface ip link set mac0 netns mac On the mac namespace, inside the VM: ip link set lo up ip link set mac up ip addr add 10.0.7.102/24 dev mac0 So that we basically end up with: (Like Inception ?) +------------------------+ | Host: 10.0.7.1 | | | | +--------------------+ | | | VM: 10.0.7.101 | | | | | | | | +----------------+ | | | | | NS: 10.0.7.102 | | | | | | | | | | | +----------------+ | | | +--------------------+ | +------------------------+ What works: Ping between Host and VM Ping between NS and NS dhclient from NS What does not work: ping between NS and VM ping between NS and Host Where I started to go nuts: tcpdump on host (the real machine) actually shows ARP request AND replies tcpdump on NS shows ARP requests sent to the host tcpdump on VM makes the whole mess work (!) -- ping starts to get answers when tcpdump is started on the VM ?!? So, I bet you were eager for it, my question is: how to I make it work ? I suspect something's wrong with ARP on the macvlan inside the NS but can't figure out what exactly... Btw, I did the same expérimentations with the mac0 interface directly on the VM (no namespace) and it worked flawlessly.
