where is the point the client command is executed?

[Zhang Kexin]

Hi,

I met some difficult in reading ssh/sshd souce code, I want to
find out how the command that user input in client is executed on the
server. I only found out the process_input function put the command in a
buffer,but can not find how it is executed. Could you please help me on
that?
Thank you very much.
