I am already running 1.5.11 and OpenSSH 3.9p1.  I'm running with the options
"-D -d -d -d".  This is the debugging output I get.

debug2: load_server_config: filename /etc/sshd_config
debug2: load_server_config: done config len = 238
debug2: parse_server_config: config /etc/sshd_config len 238

debug1: private host key: #1 type 1 RSA
debug3: Not a RSA1 key file /etc/ssh_host_dsa_key.

Attached is the output of "cygcheck -s -v -r".  Thanks in advance for any
help you can give me.
