sftp->ls creates sftp-server.exe.stackdump

[Hartmann, Josef]

Hi,


I have successfully setup openssh (openssh-2.9p2-3.tar.bz2) on my nt4sp6a
system. Logging on and scp works quite fine. However I am not able to get
sftp to work. I installed sshd as service using cygrunsrv:
$ cygrunsrv.exe -I sshd -p /usr/sbin/sshd -a '-d -d -d' -d 'Cygwin SSHD' -e
'CY
GWIN=ntsec' -1 /tmp/sshd.out -2 /tmp/sshd.err

Furthermore /etc/sshd_config is setup to run sftp:
#Uncomment if you want to enable sftp
Subsystem      sftp    /usr/sbin/sftp-server


Now when I run sftp -vvv hartmann@localhost everything works fine. I get
authenticated and logged in. However when I run "ls"
sftp-server.exe.stackdump (attached) is created and the client is locked. I
can only press CTRL-C in order to get back to the shell.
