About nncheck ============= nncheck is a Network Neutrality Checker. nncheck tries to establish outgoing TCP connections on common ports, and checks whether they are blocked (for instance, your mobile ISP might block the SIP port, 5060). The state of a port can be: * "open", which means that the connection to the responder was successful; * "closed", which means that somebody (probably your ISP) has terminated the connection; * "timeout" (only when using curl), which means that the responder has not replied within a few seconds (2 by default). Usually, ISPs do not terminate the connection, but rather drop it without noticing the initiater, leading to a timeout. It should be safe to consider this as a blocked port, but a slow connection might trigger false-positive. If you want to be certain, try running the script again or change the TIMEOUT variable in the script. Report Net Neutrality violations ================================ If you find that your ISP (especially a mobile one) is blocking some ports, you can discuss it on our irc channel, #laquadrature on irc.freenode.net. If you live in Europe, you can also visit http://respectmynet.eu : first check if your country/ISP is already on the list (in which case you can confirm and comment). If it's not, you can create a new report. Please double-check that your report is accurate (try running the script multiple time, raising the TIMEOUT value…) Adding ports to test ==================== Feel free to propose new ports to check! Please note, though, that each port might take up to 2 seconds to check (in case the port is blocked but the connection is simply dropped, not closed -- yeah, some ISPs are evil --, there is a 2-seconds timeout) Responder ========= To check whether an outgoing port is blocked, we use La Quadrature du Net's responder, available at: http://responder.lqdn.fr:<port> (eg. http://responder.lqdn.fr:6667 ) There also is a text version at: http://responder.lqdn.fr:<port>/simple.php
