İyi günler bir süredir TCP/IP protokolü ile iki windows işletim sistemine sahip bilgisayar arasında veri iletişimi yapmak için uğraşıyorum.
Kendi bilgisayarım üzerinde TCP server ve Client çalıştırdığımda herhangi bir sorun olmazken iki ayrı ve aynı ağa bağlı bilgisayarlar üzerinde birisi Server diğeri Client olmak üzere deneme yaparken sonuç alamıyorum
Buradaki eksiğim ne?
Bunun dışında C/C++ ile soket programlama ve ağ ile ilgili önerebileceğiniz kurs var mı?
