• Computer Says No: Mobile Apps Connectivity Messages

  - by ultan o'broin

  Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".

• Network switches for LAN party

  - by guywhoneedsahand

  I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

• Onboard Ethernet suddenly stopped working to router

  - by AfterschoolHobbist

  Hey guys, yesterday I have a sudden problem of my Ethernet connection to my router. My computer is a Pendium 4 with Window XP SP3 running on it and it was working fine earlier in the day, but yesterday night was the start of the problem. My computer is unable to ping to the router and to any other website and unable to get internet connection. As beside it was connected to a hub, I directly connected it to the router directly and the same problem occurred, being unable to ping to the router (and connecting to it) and still no internet access. My directly connected to the modem and the problem still persisted. For each connection, I connected it to my computer and my laptop and my laptop was able to connect, while my desktop computer was unable. I wondered if it was a OS issue and ran a live Ubuntu CD to see if Ubuntu was able to connect to the internet, but the issue persisted and I was unable to get internet access. I then set my router's lease time to 1 hour and waited. After 1 hour, the lease for my computer was removed and I hoped this worked, but it didn't work, but something strange is acting up. My desktop computer is still unable to ping to the router or connect to the internet, but for some reason, my router and desktop computer is still able to contact each other by providing a lease of an local ip address. The router record of a lease to my desktop computer, and when I do ipconfig, my desktop also recognize that it has been provided a local ip address. I have concluded that this is a hardware issue and the only solution to fix this is to by a network card adapter, but I am wondering if anyone has any solutions that could explain why this happen, why my mac address is 01-23-45-67-89-ab, and is there any way to fix it without buying a new network card? Thanks in advance.

• So what is Active GridLink for RAC?

  - by Ruma Sanyal

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 I had referred to Active GridLink for RAC in my blog yesterday and since then got several questions on this topic. So I decided to re-visit Active GridLink. With the release of version 11g, Oracle WebLogic Server started to provide strong support for the Real Application Clusters (RAC) features in Oracle Database 11g, minimizing database access time while allowing transparent access to rich pooling management functions that maximizes both connection performance and availability. WebLogic is the only application server in the marketplace which has been fully integrated and certified with Oracle Database RAC 11g without losing any rich functionality. Active GridLink provides Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. With the key foundation for providing deeper integration with Oracle RAC, this single data source implementation in Oracle WebLogic Server supports the full and unrestricted use of database services as the connection target for a data source. For more details and to understand how our customer NEC leverages this capability, read the whitepapers on this topic. Get in depth ‘how-to’ details from this youtube video from our resident expert, Frances Zhao.

• Saving small text files is slow over Win Server 2008 R2 VPN

  - by Buckers

  We have a VPN connection to our Windows Server 2008 R2 machine, and the connection works fine. Large files go back and forth fairly quickly, but we use the connection mainly for working on small text files (.aspx, .asp, .php etc). What we find very annoying is that even the smallest of files, there is a noticeable delay of between 2-5 seconds when saving any changes. As we often make changes to code and are constantly saving, this is becoming a problem. Is there anything that might be causing this delay? Or is there anything we can do to speed it up? The connection is definitely not the issue as we have a constant 5Mb upload from our server, and 20Mb+ down on the remote machines. Thanks, Chris.

• Tracking Protection List in IE9

  - by Emanuele Bartolesi

  To protect the privacy when I surf over the internet, I use AdBlockPlus add-in for Firefox. But when I use Internet Explorer 9, this add-in don’t work. Internet Explorer 9 (and I hope Internet Explorer 10) has built in feature to add a TPL. There is a javascript function to call named msAddTrackingProtectionList. This function has two parameter: the first one is the link of TPL and the second one is the Title of TPL. To do this is very easy. Add this simple javascript function on your website or in a blank html page. <a href="javascript:window.external.msAddTrackingProtectionList('http://easylist-msie.adblockplus.org/easyprivacy.tpl', 'EasyList Privacy')">EasyPrivacy TPL</a> The effect is below: EasyPrivacy TPL After click appears a confirmation prompt. For security reason this javascript function can only be called from a user interaction: buttons, links, forms. For more information about msAddTrackingProtectionList function  go to Msdn Library. For more information about EasyList go to Easy List TPL.

• Lynksys WRT120N wireless router not connecting to ADSL

  - by pradeetp

  I have a lynksys WRT120N wireless router that was connected to Sterlite ADSL modem. The internet connection was working fine through wireless access. I changed the ADSL router because it developed some power issues and got it replaced with the same model/brand from the service provider. However I am not able to access internet now. Here is the current setting Sterlite SAM300 XA IP Address: 192.168.2.1 (I changed it to this IP because the IP address of my ADSL router was same) Lynksys WRT120N wireless router IP Address: 192.168.1.1 If I connect my laptop to ADSL router directly, the internet works fine. It is only that that if I access it wirelessley through wireless router that I am not able to connect to internet. The IP address setting has been configured to obtain IP address automatically. I have windows 7 OS home edition. Could someone please help me to fix this issue.

• SSH and Latent Connections (e.g., satellite connections)

  - by user71494

  Most of the week I live in the city where I have a typical broadband connection, but most weekends I'm out of town and only have access to a satellite connection. Trying to work over SSH on a satellite connection, while possible, is hardly desirable due to the high latency ( 1 second). My question is this: Is there any software that will do something like buffering keystrokes on my local machine before they're sent over SSH to help make the lag on individual keystrokes a little bit more transparent? Essentially I'm looking for something that would reduce the effects of the high latency for everything except for commands (e.g., opening files, changing to a new directory, etc.). I've already discovered that vim can open remote files locally and rewrite them remotely, but, while this is a huge help, it is not quite what I'm looking for since it only works when editing files, and requires opening a connection every time a read/write occurs. (For anyone who may not know how to do this and is curious, just use this command: 'vim scp://host/file/path/here)

• Open ports broken from internal network

  - by ksvi

  Quick summary: Forwarded port works from the outside world, but from the internal network using the external IP the connection is refused. This is a simplified situation to make the explanation easier: I have a computer that is running a service on port 12345. This computer has an internal IP 192.168.1.100 and is connected directly to a modem/router which has internal IP 192.168.1.1 and external (public, static) IP 1.2.3.4. (The router is TP-LINK TD-w8960N) I have set up port forwarding (virtual server) at port 12345 to go to port 12345 at 192.168.1.100. If I run telnet 192.168.1.100 12345 from the same computer everything works. But running telnet 1.2.3.4 12345 says connection refused. If I do this on another computer (on the same internal network, connected to the router) the same thing happens. This would seem like the port forwarding is not working. However... If I run a online port checking service on my external IP and the service port it says the port is open and I can see the remote server connecting and immediately closing connection. And using another computer that is connected to the internet using a mobile connection I can also use telnet 1.2.3.4 12345 and I get a working connection. So the port forwarding seems to be working, however using external IP from the internal network doesn't. I have no idea what can be causing this, since another setup very much like this (different router) works for me. I can access a service running on a server from inside the network both through the internal and external IP.

• Do busy smtp servers use long running tcp connections to exchange lot of mails?

  - by iamrohitbanga

  I had this idea from http://stackoverflow.com/questions/2813326/maximum-number-of-bytes-that-can-be-sent-on-a-tcp-connection is it possible that smtp servers like gmail and yahoo enter into some form of agreement to maintain a tcp connection between them so that lots of mails could be sent on the same tcp connection. it would be efficient as there would be heavy mail traffic between these mail servers.

• Hyper-V can't connect from host to guest via RDC

  - by Mark

  As the title describes I would like to connect via Remote Desktop Connection to my VM. I want to use it as a Dev-machine and therefore would like to work full screen, as far as I understand RDC is the way to go. I have created an internal network connection within Hyper-V, assigned it to my VM, set a static IP/Subnet on guest (Win7 Pro) and host(Win8.1 Enterprise). It worked good for the first couple of times but now it seems to be broken or I have to do odd enable/disable network connection "dances" to get it running. Ping also doesn't work always so it does seem as if the guest and host would be "disconnected".. Is there something I can do so that the network connection always will be established?

• Nginx proxy with SSL Authentication

  - by Dustin Oprea

  I need to proxy an SSL-authenticated connection to another server that requires an SSL authenticated connection. I realize that the incoming and outgoing connections of the proxy may have different certificates, but is it possible to call proxy_pass and tell it to use a certificate/private key for connection to the proxied system? Based on the documentation, it doesn't seem possible. Maybe with another module?

• How do I set up a proxy server for home with bandwidth control, download limit options?

  - by Quakeboy

  3 room mates share a single 2 Mbps connection. Have a 40GB per month download limit beyond which speed drops to 256Kbps which is annoying. One of the roommates abuses the connection by downloading beyond his quota limit. I have a Netgear WNR1000v2 Wireless router + ADSL Modem to connect to the internet. We all access internet via Wireless router which connects to ADSL Modem. I need a free proxy solution which can help me set 40GB / 3 (13 GB) limit for each person (every person has 2 devices - a PC and a phone with Wifi) Uniform Bandwidth control - when 2 people browse the internet they should get 1 Mbps each, and when 3 people access, they should get 2Mbps divided by 3. After each person crosses their monthly download limit, they should be able to access the internet with 256Kbps speed only or lesser. Can I have a custom firmware on my wireless router do this (or) Do I need a proxy server ? Please point me to any relevant tutorials (for example with Squid).

• Routing connections through VPN based on hostname (not IP range)

  - by Michal M

  This bugs me immensly. I need to connect to client's network through VPN. But I definitely do not want to send all the traffic through client's network so this option is out of question. What I need basically is for the OS to know that all client's network subdomains (*.example.com) need to go through the VPN connection. I tried a couple of options: Changing order of services and setting the VPN on top, but this works the same as "Send all traffic over VPN connection". Using "VPN on Demand" option from network advanced options, but this feature is quite rubbish to be honest. Seems to work only in Safari (?!) and it doesn't route the connection, but it basically triggers the OS to connect to the selected VPN. The reason I need it to work based on hostnames rather than IP range is simple - my client has a lot of servers inside his network and it's impossible for me to remember all IPs. They are all within a range, but this doesn't help me remembering. Another option would be to put the VPN connection on the bottom of network services and untick "Send all traffic..." and then put all known hostnames in hosts file, but considering there could be hundreds of servers (therefore hostnames and ips too) it ridiculous job. And if new server appears on the network I'd need to edit the hosts file again. Sisyphean labours. However this works on Windows very simply. If a hostname is not available through default network interface, then it seems to try VPN connection and this works brilliantly. So, how can I achieve that on Mac, then? I know client's internal DNS addresses if that is of any help (like directing a certain domains through a different DNS)? PS. Using latest version 10.6.6. PS2. I am using VPN to access intranet, version control servers (svn://), samba shares and for SSH access to servers.
