  • Firefox can't establish a connection to the server at www.google.com

    - by Tom
    My home page in Firefox [v4.0] and Internet Explorer [v9.0.8112.16421, Update Versions RTM (KB982861)] is currently set to Google but when I depress the quick start icon to start up either browser, I am getting the following immediate results: Unable to connect (In Firefox) Firefox can't establish a connection to the server at www.google.com. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. Internet Explorer cannot display the webpage What you can try: Diagnose Connection Problems More information This problem can be caused by a variety of issues, including: Internet connectivity has been lost. The website is temporarily unavailable. The Domain Name Server (DNS) is not reachable. The Domain Name Server (DNS) does not have a listing for the website's domain. There might be a typing error in the address. If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.

Thankfully, I am able to use one browser that I have installed on my computer (Mathon v3.0.20.5000) to search online for technical assistance in this matter. I have seen several WinSock error issues mentioned; but, they are pointing to Windows XP and I am using Windows 7 Pro and remain uncertain whether anything identified as a fix for one OS will work in another. Things I've tried: HiJackThis Complete scan with Avira AntiVirus Premium. What am I overlooking? What should I do to address this problem?

  • Hooking thread exit

    - by mackenir
    Is there a way for me to hook the exit of managed threads (i.e. run some code on a thread, just before it exits?) I've developed a mechanism for hooking thread exit that works for some threads. Step 1: develop a 'hook' STA COM class that takes a callback function and calls it in its destructor. Step 2: create a ThreadStatic instance of this object on the thread I want to hook, and pass the object a managed delegate converted to an unmanaged function pointer. The delegate then gets called on thread exit (since the CLR calls IUnknown::Release on all STA COM RCWs as part of thread exit). This mechanism works on, for example, worker threads that I create in code using the Thread class. However, it doesn't seem to work for the application's main thread (be it a console or windows app). The 'hook' COM object seems to be deleted too late in the shutdown process and the attempt to call the delegate fails. (The reason I want to implement this facility is so I can run some native COM code on the exiting thread that works with STA COM objects that were created on the thread, before it's 'too late' (i.e. before the thread has exited, and it's no longer possible to work with STA COM objects on that thread.))

  • Passive and active sockets

    - by davsan
    Quoting from this socket tutorial: Sockets come in two primary flavors. An active socket is con­nect­ed to a remote active socket via an open data con­nec­tion... A passive socket is not con­nect­ed, but rather awaits an in­com­ing con­nec­tion, which will spawn a new active socket once a con­nec­tion is es­tab­lished ... Each port can have a single passive socket binded to it, await­ing in­com­ing con­nec­tions, and mul­ti­ple active sockets, each cor­re­spond­ing to an open con­nec­tion on the port. It's as if the factory worker is waiting for new mes­sages to arrive (he rep­re­sents the passive socket), and when one message arrives from a new sender, he ini­ti­ates a cor­re­spon­dence (a con­nec­tion) with them by del­e­gat­ing someone else (an active socket) to ac­tu­al­ly read the packet and respond back to the sender if nec­es­sary. This permits the factory worker to be free to receive new packets. ... Then the tutorial explains that, after a connection is established, the active socket continues receiving data until there are no remaining bytes, and then closes the connection. What I didn't understand is this: Suppose there's an incoming connection to the port, and the sender wants to send some little data every 20 minutes. If the active socket closes the connection when there are no remaining bytes, does the sender have to reconnect to the port every time it wants to send data? How do we persist a once established connection for a longer time? Can you tell me what I'm missing here? My second question is, who determines the limit of the concurrently working active sockets?

  • Can't open COM1 from application launched at startup

    - by n0rd
    I'm using WinLIRC with IR receiver connected to serial port COM1 on Windows 7 x64. WinLIRC is added to Startup folder (Start-All applications-Startup) so it starts every time I log in. Very often (but not all the time) I see initialization error messages from WinLIRC, which continue for some time (couple of minutes) if I retry initialization, and after some retries it initializes correctly and works fine. If I remove it from Startup and start manually at any other moment it starts without errors. I've downloaded WinLIRC sources and added MessageBox calls here and there so I can see what happens during initialization and found out that CreateFile call fails: if((hPort=CreateFile( settings.port,GENERIC_READ | GENERIC_WRITE, 0,0,OPEN_EXISTING,FILE_FLAG_OVERLAPPED,0))==INVALID_HANDLE_VALUE) { char buffer[256]; sprintf_s(buffer, "CreateFile(%s) failed with %d", settings.port, GetLastError()); MessageBox(NULL, buffer, "debug", MB_OK); hPort=NULL; return false; } I see message box saying "CreateFile(COM1) failed with 5", and 5 is an error code for "Access denied" error according to this link. So the question is why opening COM-port can fail with such error right after booting Windows and proceed normally few seconds or minutes later?

  • pfSense: How to route traffic out the WAN port?

    - by Ian Boyd
    Expert version i want to create a route in pfSense that will send traffic out the physical WAN port, not the PPPoE WAN port. i want to talk to talk to the web-server on my DSL modem, but it doesn't see packets wrapped in a PPPoE header. Long version My pfSense router is responsible for setting up the PPPoE connection over DSL to my ISP. When a machine on the LAN wants to sent packets to the internet, the default route sends packets out over the PPPoE connection. Those packets, wrapped in a PPPoE header, are sent on the ethernet cable to my DSL modem. From there they are sent the ISP, and the internet at large. i want a way to send a packet out the WAN port itself - not the PPPoE WAN port. My modem is sitting out there, with a http interface where i can monitor connection speed signal-to-noise ratio bandwidth connection time Whenever i try to set a route for destination of 192.168.2.1 (the IP that the modem will listen to for HTTP requests) to go out the WAN port, they instead end up going out the PPPoE port. The difference being that they're wrapped in a PPPoE protocol packet, and the modem isn't being sent the packet, it's being delivered to the ISP. Given that pfSense has no ability to direct traffic out the physical WAN port: how can i direct traffic out the physical WAN port on pfSense?

  • DNS, subdomain, and IPv6 -- possible to add subdomain.example.com NS record to an IPv6 host?

    - by mpbloch
    example.com is listed with a registrar -- specifically, answerable.com. I want to host a subdomain in-house, specifically home.example.com. I am using an ipv6 gateway, specifically gogo6, to have a public IPv6 address. The IP address looks like 2001:xxxx:xx47. Then http://[2001:xxxx:xx47] goes to my test site (an instance of IIS7). I can add a quad-A record for my primary site -- home.example.com AAAA 2001:xxxx:xx47. Then http//home.example.com loads correctly. Must I add an A or quad-A record for all sub.home.example.com to my answerable.com DNS manager for example.com? Or can I delegate DNS queries to *.home.example.com to the machine at [2001:xxxx:xx47]? I have tried to add a AAAA record for tunnel.example.com to [2001:xxxx:xx47], and then add an NS entry for home.example.com to tunnel.example.com, but browsing then results in "DNS lookup error" from my browser. Is this a configurable scenario? Can DNS for subdomain only be delegated to IPv4 addresses?

  • Using PHP and cURL to login to indyarocks.com

    - by Divya
    I am new to cURL and don't know much about it. I basically want to login to my account on www.indyarocks.com through libcurl for PHP. I don't know what type of authentication it uses (I don't know how to find that out.). When I go to http://www.indyarocks.com, I get a login form which asks for my username and password. I put in my username and password and click login and everything is good. I tried to automate this using cURL. This is a snippet of my code. curl_setopt($curl_connection, CURLOPT_URL, "http://www.indyarocks.com/loginchk.php"); curl_setopt($curl_connection, CURLOPT_POST, 1); curl_setopt($curl_connection, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl_connection, CURLOPT_USERPWD, $username.':'.$password); I looked at the source of the login page and found out the address of the page to which the username and password are sent (the action attribute of the form) which is "http://www.indyarocks.com/loginchk.php" and set it as the target url. When I run this, I get username or password is wrong error and the login fails. My username and password is correct. I don't know what the problem is. Can the password be encrypted? Can that be responsible for this failure? Please help me get around this problem. I'll be really thankful. Thanks in advance.

  • What is an interface in C (COM) is it the same as a interface in C#

    - by numerical25
    Ok, I know what a interface is, but since I got into C and working with COM objects, it seems an interface in COM is a little different from the interface I know of. So what I am trying to do is bridge the gaps here cause since I been learning C, alot of things have been sounding very familiar to me but are not exactly what they seem. The interface I know of are like contracts. They are objects that have only method declarations, with no body. All classes that implement an interface must include the methods of the interface. The interface I hear about in COM seems to be just pointers. They can not retrieve objects directly but only can retrieve objects through the means of a method. Is this what a COM Interface is ?? If so, then why did they give them the same names if they are completely different. Also I just wanted to add that headers in C++ kind of remind me of the C# Interfaces. Not sure if their are any relations. But anyways, I am just trying to clear that up.

  • Can I have a virtual firewall forward packets to another virtual machine on the same server?

    - by cowgod
    I currently have a web server running Apache using iptables for a firewall. What I would like to do is setup a new machine with XenServer and install two virtual machines--one running IPCop and one running Linux with Apache. Then I would configure IPCop to have the external IP address and forward port 80 to an internal IP on the second virtual machine. Is this even possible?

  • How to access an IP address as if on a different network using SSH

    - by NT3RP
    In preparation for a lengthy business trip, I set up my router such that I can access my home computer over the internet via port forwarding over SSH. One thing I neglected to do was setup access to my router remotely. Normally, I can just access the router configuration page via 192.168.1.1. I know that it's possible to tunnel traffic through SSH, but how do I access an IP address as if I were on my home network using SSH?

  • Set up simple reverse proxy using IIS

    - by Ropstah
    I would like to reverse proxy my Jira installation on a Windows server 2008 machine. Jira is running under: http://jira.domain.com:8080/ and is accessible as such. The machine also runs IIS for hosting several ASP.NET websites. I followed instructions here: http://blogs.iis.net/carlosag/archive/2010/04/01/setting-up-a-reverse-proxy-using-iis-url-rewrite-and-arr.aspx and installed URL rewrite and ARR. I now have a “Web farm” node in my IIS instance but I’ve got no idea on how to proceed. I tried adding some rules but this made the rest of my IIS websites stop responding. Is there a simple way to say: 1. Forward http://jira.domain.com to http://localhost:8080 2. Ignore other domains and route them as usual Any help is greatly appreciated!
