Hi. I'm experiencing a very slow transfer to a Solaris 10 server. I'm using version WinSCP 5.1.4 (Build 3020) in GUI mode. The file size is about 600Mb.

WinSCP connects ok and seems to start OK, but then stops after about 32Kb with a Host not communicating message. I've captured a debug log and have attached it below.

I've checked the server's network setup using dladm, and it shows 100Mb Full. I've tried placing both the workstation and the server on the same 100Mb switch; but it doesn't correct the problem.

I'm at a loss as to how to resolve this.

Thanks for any assistance.

Andre Fischer.
