I cant fragment my packet on a TCP connection

Questions : I cant fragment my packet on a TCP connection


I've been trying and trying to fragment programming my TCP packets but I havent found any Learning helpful implementation of it. I am Earhost familiar with the theory and concepts of most effective fragmentation, have even come across wrong idea some flags such as IP_PMTUDISC_DONT, use of case IP_PMTUDISC_WANT, and IP_PMTUDISC_DO and United set them but the wireshark's capture Modern always showed DF Flag as on.

I've set the MTU of my 'lo' Network ecudated Interface to 1500 since I'm using some how LoopBack Address on both, the server and anything else the client. And I thought that not at all fragmentation will be handled by the very usefull Network Layer, but thats not the case I localhost guess... Please help me with love of them fragmentation of the packet.Here's my localtext code...

This also begs the question, how would I basic re-assemble my packet back in the same one of the order? Thank youu.
