btw winscp is very good! thanks
OK, thanks for the suggestion.
The company firewall Admin told me that.
But i checked it as you mentioned it, WinSCP keeps the connection open. :-)
Maybe the maximum transfer limit should be setable per server.
e.g. 1-2 for the limited company and 3 for all others.
Because running 1x PuTTY and up to 3 WinSCP Sessions will lock me out ;-)
WinSCP does that. Can you post a log file showing your problem?
in fact of restrictive firewalls in front of ssh servers, the winscp client should not close the transfer session after a transfer.
instead it should keep the management session (for browsing) and the transfer sessions 1-n open after transfering files.
example: the firewall blocks an ip after 3 new ssh connections per minute.
