Hello , OpenSSH gurus I am writing an SSH server but I have some problems when testing with your client - I do not recieve any window adjustments. The situation is something like this - I am exchanging data and sending window adjust after every packet, but do not get any window adjust packets. I tried to lookup the place in the source - OpenSSH-2.92p2 - but didn't find it. Can you help me - I

It also won't call channel_handle_wfd, which would in any case return directly, which means that c->local_consumed won't be updated either. This means that channel_check_window won't ever send a SSH2_MSG_CHANNEL_WINDOW_ADJUST message, and eventually the server will stop sending and wait for the client to catch up, which will never happen. I could reproduce this easily on Linux by doing ssh localhost dd if=/dev/zero bs=1024 count=256 > /dev/full to see the hang, and ssh localhost dd if=/dev/zero bs=1024 count=1 &g...

Hello I have ported OpenSSH 3.8p1 to a LynxOS platform. Recently I heard a report from the field that v2 is perceived to be significantly slower than v1. Is this a known issue? Are there any configuration parameters that can be modified to make v2 faster? Thanks in advance for your response Amba
