  • How do I get netcat to accept connections from outside the LAN?

    - by Chris
    I'm using netcat as a backend to shovel data back and forth for a program I'm making. I tested my program on the local network, and once it worked I thought it would be a matter of simply forwarding a port from my router to have my program work over the internet. Alas! This seems not to be the case. If I start netcat listening on port 6666 with: nc -vv -l -p 6666, then go to 127.0.0.1:6666 in a browser, as expected I see a HTTP GET request come through netcat (and my browser sits waiting in vain). If I go to my.external.ip.address:6666, however, nothing comes through at all and the browser displays 'could not connect to my.external.ip.address:6666'. I know that the port is correctly forwarded, as www.canyouseeme.org says port 6666 is open (and when netcat is not listening, that its closed). If I run netcat with -g my.adslmodem's.local.address to set the gateway address, I get the same behavior. Am I using this command line option correctly? Any insight as to what I'm doing wrong?

  • Routing and authenticating all access through squid

    - by Knight Samar
    Hi, I want to route all Internet access in my network through a Squid proxy server and authenticate and log all users. I want this to be a client-independent setting so that no one needs to do anything on their browsers or machines. I have set my network gateway as the proxy server so that all traffic will be sent to it. I have done this using options in DHCP server. Now I tried using squid as a transparent proxy, but then it won't authenticate in that mode. I tried using iptables to route all traffic to port 3128 but it won't popup the authentication dialog box from SQUID. I tried telling DHCP to give WPAD to all clients by placing a WPAD file on a webserver containing the following for automatic proxy configuration on clients: Changes in dhcpd.conf option wpad code 252 =test; option wpad "\n\000"; option wpad "http://192.168.1.5/wpad.dat\n"; The WPAD file: function FindProxyForURL(url,host) { return "PROXY squid-server-ip-address:3128 ; DIRECT "; } But the browsers (different versions of Firefox and IE) seem to ignore it. :( What should I do ?

  • Virtualhost one https site, the rest http

    - by RJP1
    I have a linode server with Apache2 running a handful of sites with virtualhosting. All sites work fine on port 80, but one site has a ssl certificate and also runs okay. My problem is as follows: The non-https sites, if visiting https://domain.com - show the contents of the only secure site... Is there a way of disabling the *:443 match for these non-secure sites? Thanks! EDIT (more information): Here's a typical config in sites-available for a normal insecure http site: <VirtualHost *:80> ServerName www.insecure.com ServerAlias insecure.com ... </VirtualHost> The secure https site is as follows: <VirtualHost *:80> ServerName www.secure.com Redirect permanent / https://secure.com/ </VirtualHost> <VirtualHost *:80> ServerName secure.com RedirectMatch permanent ^/(.*) https://secure.com/$1 </VirtualHost> <VirtualHost *:443> SSLEngine on SSLProtocol all SSLCertificateChainFile ... SSLCertificateFile ... SSLCertificateKeyFile ... SSLCACertificateFile ... ServerName secure.com ServerAlias secure.com ... </VirtualHost> So, visiting: http:/insecure.com - works http:/www.insecure.com - works http:/secure.com - redirects to https:/secure.com - works http:/www.secure.com - redirects to https:/secure.com - works https:/insecure.com - shows https:/secure.com - WRONG!

  • html5 video secure streaming?

    - by citizenmatt
    Does html5 allow me to do secure streaming video? And by this, I mean token authentication. I want to be able to stream media only to those people who are authorised to view it. I can do this currently with Flash Media Server hosted by Akamai - they have a custom mechanism where I send them a token as part of the player connection handshake. Does html5 allow for this, and has anyone implemented this with a hosting service such as Akamai? Thanks Matt

  • simple yet secure encrypt / decrypt asp to asp.net

    - by Michael
    First post here. I have a asp/vb6 web app that logs in a user I want to encrypt the users identity field and pass(querystring) it to a asp.net app and then decrypt it to do a db lookup. I've google'd it of course and found rot13, not secure enough. I've also found some hits on MD5 / RC4 but did not find any good examples of encrypt / decrypt. Thanks, Michael

  • Secure Streaming CDN Video Content

    - by Donalds
    Hi, I am using Amazon CloudFront to stream paid video content to my users and I am having problems getting the videos secured. Wowza does that by creating a secure token, but the use of wowza would be much more costly. Is there anyway that I can better protect my content by using Cloudfront or other CDN? Thanks!

  • which is the most secure way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most secure way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.

  • IE6 secure and nonsecure error - nothing in Fiddler/no iframes

    - by seengee
    Hi, I've got the issue of IE6 showing the "secure and nonsecure items" error on an SSL page. Looking into it though none of the usual causes seem to apply. There are no calls to http://, there are no iframes in the page, fiddler and httpfox both show only requests to https:// - what else can i check? In Firefox and IE there is nothing to suggest there is mixed content at all

  • secure xmlhttprequest from nonsecure page

    - by amwinter
    I want to make an XMLHttpRequest to a secure uri (https://site.com/ajaxservice/) from javascript running inside a nonsecure page (http://site.com/page.htm). I've tried all kinds of nutty stuff like iframes and dynamic script elements, so far no go. I know I am violating 'same origin policy' but there must be some way to make this work. I will take any kind of wacky solution short of having the SSL protocol written in javascript.

  • How to keep PayPal variables secure

    - by dclowd9901
    I'm trying to link my 3rd party shopping cart to PayPal, and in the process I'm finding that my variables are extremely exposed, such that, if someone uses, say, Firebug, to manipulate the values of my variables, they can change the cost of the items in the transaction. I'm very new to online carts and shopping, so my question is how do I keep this layer of exposure away from users and secure for the website?
