ssh connection drops

jeffpoulsen · 10-08-2003, 06:55 AM

I am running RH9 as a server. I use WinScp to upload files on my local as well as from the wan. I have had very few problems in the past, but now I cannot load a large website. The connection is opened and the transfers started. After a few minutes the connection is dropped by the server. I have tried to slow the upload bit rate. No change. I wonder if some of the updates I have installed lately have caused this problem? Also I hope some one can tell me where to look for and fix this problem. Thanks, jeff

I hope you know about the bugs in ssh.

BTW it would help if you quote the version of sshd and what OS you have installed!

Are you by any chance running a firewall on the client machine (which appears to be a Win box)? I have seen problems with users who block certain ports. If you do, just disable the firewall temporarily and try again.

Give it a shot.

I am running the ssh program that ships with RedHat 9. I am using a windows box to connect but have never had problems before. I did try to shut down the fire wall on both machines, but that didn't help. It handles individual files fine, but seems to (choke) on lager files, like over 2 mb. Is there something to with buffer over runs that could be affecting the transfers? All help is appreciated

I hope someone is able to help. I can't find any resources for the problem. I still think it has to do with the updates to ssh from RedHat.

I don't know about this WinSCP. I use cygwin's command-line scp without problems. Maybe you want to try that? Cygwin is indispensible anyway, if you don't have it yet, get it. When you install, you get a configure GUI and you need to enable the openssh
tools. www.cywin.com.

The other thing you could try to pinpoint the cause problem is to scp a file from the redhat box to itself, using not localhost, but the actual IP. If that works, it looks more like a problem with WinScp.
