I'm not sure, that this is fault of WinSCP. "connection reset by peer" message means that it was not client who closed connection.
I have SSH-1.99-OpenSSH_3.4p1on a Linux machine and told a Windows user to use WinSCP2 to access it; I think he has version 2.0.0. and is using a dialup line across the Atlantic (maybe 150ms trip).
He was getting very annoyed because evey time he tried to access a directory with 500 files the program disconnected with a message "connection reset by peer".
When I try winscp2 via NAT from my cable modem it seems OK. I normally use OpenSSH on Linux and have never had any similar problem.
Has anyone seen this problem ?
Is it fixed in the latest version ?
(please email if you know)
