QtNetwork send ICMP Packet

[SlowTree]

Hello everybody,
i'm trying to create a simple ICMP Packet sender with Qt4, i would like to know if is possible to send ICMP Packets throw QAbstractSocket Extension or by another way.
I saw that using std socket it is possible (but as usual using IP RAW & u need root privileges on Linux) but i would like to use qt framework not only for GUI but also as Core engine for my app.
Thanks,
Bye Bye...

Hi,

you've to know the structure of the ICMP protocoll, than you're able to build such a package, using QTcpSocket. If you don't want to enter this topic so intense, you can use a portable Library like libpcap ( and winpcap on Windows ).

If you want to write such a lib manually, you've to take a look on RFC 792 ( http://www.faqs.org/rfcs/rfc792.html )

Hi. I'm sorry I'm waking up this topic, but I have the some questions.

Well, I want to build my own ICMP packet:
- can this really be done using QTcpSocket?
- how can I start building one... by appending certain bits into a QString or what... Any tips will do!

I want to build a ping program based on ICMP packets and the hard thing to do is build a ICMP packet, so I need some help. Thanks
