Hi, Why not turn off TCP_NODELAY in OpenSSH, atleast in the server->client direction? If a user is doing 'ls -l' over an Internet link that has some latency, he/she is flooded with a burst of small packets that can cause congestion and packet loss. Quite many people have been noticing this behaviour when doing ls -l resulting in <output> <delay> <output> <delay> etc, but they usually think that the link is bad. SSH Inc's sshd 3.0.1 does not use TCP_NODELAY (by default) and does not show the <output> <delay> <output> behaviour either. -Tomas
