Hello
I need a Raw Socket C Programmer to make a simple code to send a packet with some changed information on frame, like:
ip header (ttl, src, checksum, ...)
udp header (data, checksum, ...)
tcp header (winsize, ttl, mss, checksum, tos, flags ....)
data information...
basically, all informations we can get on a .pcap file
my main focus is on TCP.
Hello
I'm interesting your project very well
I'm a Good C/C++, Network expert.
I m quite well experienced in these jobs.
Let's go ahead with me
I want to service for you continously.
Thanks
Hi. We are a group of experienced engineers with different backgrounds (telecommunications, electronics and systems) with experience in technologies like C/C++/C#/Java/Linux/Scripting, who work for a telecommunications company. Along these years we have worked mainly with embedded systems, for example, high availability communications servers and cable modems.
Since we have experience implementing networking applications in both Windows and Linux environments we think that we are suitable for this job.
Could you please provide more details about what needs to be done? So that we can adjust the bid.
So far, we have the following questions:
- Do you need to run the program in a Linux-based computer?
- Do you need a command-line application?
Best regards,
Matias.-
Basicamente você quer ler pacotes gravados num arquivo .pcap, modificá-los e retransmiti-los, certo?
Parece um bom projeto. Já mexi bastante com a libpcap (e a winpcap no Windows também)...
I have significant experience in c programming and socket programming. I have worked on implementation of network standards, which involved making of the frames to be sent over the network and parsing of the received frames for headers and data in the linux environment.
I am confident that I will be able to deliver frame generation/parsing/modification code in good time.
