Detailed Description

Implements a simple mDNS responder using Qt.

This implementation is able perform mDNS queries and mDNS responses in any operating system supported by the Qt network module.

You can obtain the IP of an mDNS device using the lookup() function, the hostFound() signal will be emitted whenever this class interprets a mDNS response packet and obtains valid information about a remote host.

You can change the name that the local computer uses to identify itself in the mDNS network using the setHostName() function.

Todo

Implement NSEC block code generation in the sendResponse() packet

Member Function Documentation

getAddress()

QString qMDNS::getAddress ( const QString & string )

Ensures that the given string is a valid mDNS/DNS address.

Definition at line 168 of file qMDNS.cpp.

getInstance()

qMDNS * qMDNS::getInstance ( )

static

Returns the only running instance of this class.

Definition at line 151 of file qMDNS.cpp.

hostName()

QString qMDNS::hostName ( ) const

Returns the mDNS name assigned to the client computer.

Definition at line 160 of file qMDNS.cpp.

lookup

void qMDNS::lookup ( const QString & name )

slot

Performs a mDNS lookup to find the given host name.

If preferIPv6 is set to true, then this function will generate a packet that requests an AAAA-type Resource Record instead of an A-type Resource Record.

Definition at line 195 of file qMDNS.cpp.

setHostName

void qMDNS::setHostName ( const QString & name )

slot

Changes the host name of the client computer.

Definition at line 274 of file qMDNS.cpp.

setTTL

void qMDNS::setTTL ( const quint32 ttl )

slot

Changes the TTL send to other computers in the mDNS network.

Definition at line 184 of file qMDNS.cpp.
