Issue
SSH connection My system is Ubuntu 20.04 MTU (maximum transmission unit ) size 1500 default and try to remote connection another systems over ssh protocol
Question is ssh connection successfully done but in wireshark i saw the packets above 1500 bytes size.
I didn't know what is happening there.please someone explain how packets handle by ssh protocal above 1500 byte
thank you advance
Solution
mtu is handled on the 3rd OSI level and ssh is 7 level. So ssh knows nothing about mtu, fragmentation happens in the system's tcp/ip stack (kernel) later, after ssh sent it's data to a socket.
It would be easier if you provided some screenshots, but I believe you saw packets before fragmentation.
