during the copying WinSCP fails

This happens to me mainly with big files (>300MB) but sometimes with the small ones too. Sometimes the WinSCP fails in the middle, sometimes in the beginning, somethimes in the end (still the same file). I transfered about 2-3 gigs to until the 500MB file was finally transfered OK.
This is the error message I see very often:
"Spojen bylo neoekvan ukoneno. Server poslal ukonovac status pkazu 0."

I used WinSCP to copy the files on LAN between Linux and Windows machines.
Important is the fact, that the transfer speed is about 1MB/s.
When I use to copy the same file with putty scp (pscp), it succeed always on the first time and the transfer speed is about 2MB/s.


Where should be the problem?

Re: during the copying WinSCP fails

What transfer protocol are you using with WinSCP and what with PSCP?

Default transfer protocols, I did no change. Just now I have downloaded new WinSCP and did a proof, but with same results as before :(
How can I find out which protocols I am using? In WinSCP there is "Preferred protocol version" set to 2.

Obtained from pscp with "-v" parameter:
Server version: SSH-1.99-OpenSSH_3.5p1
We claim version: SSH-1.5-PuTTY-Release-0.53b
Using SSH protocol version 1
...
Encrypted session key
AES not supported in SSH1, skipping
Using Blowfish encryption
Trying to enable encryption...
Successfully started encryption

Thanks.
Petr

I've meant transfer protocol (SCP/SFTP), not version of SSH protocol. In WinSCP actual transfer protocol is indicated on the status line.

Unfortunatelly it seems that SCP does not tell the protocol it uses. But as you use SSH1 with PSCP, it is by sure SCP, because PSPC use SFTP only with SSH2.

Have you checked the server log to see why it disconnected the client?

With newest WinSCP client are in the status bar following informations:
- SSH protocol version 2
- aes
- SFTP (v3)

Where can I find server log if its still important?
Or where in the menu can I force the WinSCP to use SCP with SSH1?
Thank you.

SSH tab of login dialog.
