...et me try again with a simplified version, in the hope that some nice OpenSSH developer could please provide an answer. What is the rationale underpinning the sending of a window adjust packet, as implemented in channels.c? Until recently, the condition c->local_window < c->local_window_max/2 && c->local_consumed > 0 where, if I understand it correctly, local_window is the current size of the window, local_window_max is the maximum window size initially agreed on by client and server, and local_consumed is number of bytes already consumed in the current wind...

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

Greetings, I've been doing a little testing with the stdio forwarding support added in recent snapshots and have encountered one possible issue. First, I should say that this feature generally seems to work. However, I haven't been able to get it to work when connecting to a server running SSH.COM's product. The config file I am using is fairly simple: Host sfe1 LogLevel debug3
