Data transfer is blocked

Post by aither » Mon 01 Feb 2010 11:12

Hello

I have strange problem with SSH stuff. I use direct data transfer (no port forwarding). Transfer works but at same point client sends data to server and server doesnot receive it. OutCount property on client side is zero, but data dont reach server (or not sent - i dont know).
Problem can occur at the first datatransfer or after 20 hours of transfer.
On LAN it works better (occurs later). If used over Internet - usually occurs within 10 minutes or so. To continue data transfer server and client application must be restarted. Restarting only one application doesnot help.

We haven't encountered this problem before. It seems that this problem is connected with network or firewall settings.
Please check if this problem is arised when you use SSH client demo and SSH server demo projects.

There is another problem related to it. I have test applications which permanently send short messages each to other
When I shutdown the server, client is disconnected also but not shut down
When I start server again, client connects to it, sends a message (often the message which had to be sent before disconnect - something like not flushed buffers), server sends response and after this transfer is blocked.
