Can i make ICMP protocol to use QTcpsocket?

[remnant24c@nate.com]

Hello, there.

I'd like to reviice the data of 'ping'. so onesome said "QProcess". However

I want to use QTcpsocket because of next version.

return to the subject,

Can i make ICMP protocol with QTcpsocket.

or use Winsock2 socket. I found source made by C . It used Winsock2.


If i made a struct of Ip header and icmp , how should i start init(), sendto().

thank for watching.

Have nice day.

The following link have what you want. Please see the post number 6 of the thread.

Yes ! Whatever you can do with Winsock can be done with QTcpSocket. But ICMP is not a part of IP stack not TCP stack. So I am not sure that it can be achievable using QTCPSocket. But Qt have several more networking classes you can use them like:
QAbstractSocketQUdpSocketQNetworkAccessManager

Forget point to point match of winsock and qtcpsocket. You have to implement the ICMP protocol in QTchSocket. It wors like this:
1. Connect to host
2. Put some data over socket
3. Read some data from socket
4. Disconnect

No, of course not.

These are not TCP sockets, these are not bound to any
protocol yet, so you can bind them to any protocol, ICMP included. QTcpSocket is for handling TCP protocol.

BTW. Crafting ICMP packets may require superuser privileges.
