I have a scenario where multiple clients connect to a TCP server. When any of the clients sends a packet to the server, the server is supposed to have a retransmission timer and keep sending that packet to another server until it receives a reply. How do I go about setting up this retransmission mechanism? I'm doing this on Linux in C.
Show us the code you have, or the ideas you intend to implement?
You've basically just said: "I want to write a search engine. How can I do this?" or some equivalent.
Your first reply should really answer the question: "Have you made a piece of code that accepts TCP clients, or that can send a single packet?". If the answer's no, maybe you should try to walk before you run...
- Compiler warnings are like "Bridge Out Ahead" warnings. DON'T just ignore them.
- A compiler error is something SO stupid that the compiler genuinely can't carry on with its job. A compiler warning is the compiler saying "Well, that's bloody stupid but if you WANT to ignore me..." and carrying on.
- The best debugging tool in the world is a bunch of printf()'s for everything important around the bits you think might be wrong.
It would be nice to know a bit more of this. What's the purpose here? TCP itself is a protocol taking care of retransmissions if needed.
Obsession to networking and protocols made me cook up these:
NSN - Network Status Notifier
epb - Ethernet Packet Bombardier
T.H.O.N.G.S - Textmode Helper On Network Getting Sniffed
Nibbles - console UDP print listener/filter + something else
Feel free to try, comment and improve =)
