Hi folks, Could you tell me which function in clientloop.c is responsible for reading user keyboard input? What I found are client_make_packets_from_stdin_data() and client_process_input(), but they not for 'compat20' mode. My app runs in 'compat20'. Thanks, Bob

Using OpenSSH_8.3p1 I had an open (working) connection to some other box; after a bit of inactivity, some device in the middle seems to have forgotten about the TCP connection (NAT) and broke it. I've got an EscapeChar defined, though; so first I tried to send a BREAK and, when that didn't help (TCP already gone, packets get lost!), I tried (just out of curiosity) a Rekey. Now I can see
