Re: Use of openssh 3.6/3.6.1 seems to make some dos generated stdout drop


I?ve been having the same problem with sshd running as a service on XP Pro.?
I lose part of the output of some native win32 console apps when I ssh to
the machine.? The same commands run fine from rxvt or the cygwin console.?
The problem is most annoying when using ?nmake? (from visual C++), as Fred
has already noted, but also when using the ?net? tool. ??When I type ?net?
at the command prompt I usually get a summary of command syntax.? Running
the same command in an ssh session results in one blank line.? The win32
?help? command also generates no output, but ?dir? is unaffected.? I tried
running ?cmd? from within my ssh session and starting the applications from
within the windows console, to no avail.? I?m running OpenSSH 3.6.1p1.? 
?
I have included a cygcheck report as generated during an ssh session -
hopefully this will help someone track down the problem.
