Hi, Just got on this group and wonder if anyone can help. I ported Openssh-2.1.1p2 to windows to use with our emulation software. Sometimes via ssh 2 I get a bad packet length when doing repeated keystrokes(Sit in vi and append then hold down a key for a bit). For the most part it works but I suspect the ported code base had flaws that can not be fixed without porting a newer codebase.... Tell me it ain't so..... :-) I have 2.9.9 and 3.0.2 on a sun and two different NetBSD machines and it does it occasionally on them all. What do I need to do?

I have never seen the issue and I can't replicate it with 3.0.2 using your above recipe. -d
The client is the 2.1.1 code which I ported and the server behaves the same for any recent server 2.9 or newer. I am not saying that it is not in a change I made in our port. It could be there but sftp and scp and most ssh2 sessions work. I do not know if there is a timing glitch in my windows code or something long since fixed in the base code. We do not run a sshd on our client systems but generate multiple ssh sessions to hosts as needed. -----Original Message----- From: Damien Miller [mailto:djm at mindrot.org] Sent: Thursday, February 14, 2002 5:40 PM To: Taylor, Bill Cc: openssh-unix-dev at mindrot.org Subject: Re: Bad packet length rarely but still too often On Thu, 14 Feb 2002, Taylor, Bill wrote:> Hi, > > Just got on this group and wonder if anyone can help. > > I ported Openssh-2.1.1p2 to windows to use with our emulation > software.
