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

Hi, How do the communication between sshd and program happens when compat20 is enabled? There are two function process_buffered_input_packets and process_input, but in both cases if compat20 is enabled its just buffering the packets, but how do sshd will the command to program for execution? Regards prasad

...e 'read failed'; 'input open -> drain'; 'input open -> closed'; 'send eof' sequence. *Then* 'session_free' is called (as part of session close), and we end up back in session.c. Next (in serverloop.c) is called 'channel_after_select' which calls channel_handler. This calls (in our case we are using protocol 2) 'channel_post_open_2', which calls 'channel_handle_rfd' which (eventually) calls 'chan_read_failed' because the channel still hasn't been closed. As such in the original openssh we get the final - debug1: channel 0: r...

Hi OpenSSH developers, I am using openSSH (now 2.9.9p2, but prob occurs in 2.9p2 also) to execute commands on a remote machine which outputs data to stdout then pipes it to another invocation of ssh which connects back to the first machine in the same way, where it starts a program to read and store the output from the command on the second machine. I am using the "command" option in
