Before I was use openssh 3.4.1 on the Solaris 8 platform. Afterwards I
upgrade the ssh to 3.6.1 its download from sunfreeware package. The
ssh feature is work fine but sftp doesn't work normally. The sftp can
let you to type password for login. However, the error will be shown
"Request for subsystem 'sftp' failed on channel 0 Connection closed".

I've clarified the sshd_config file, "Subsystem sftp
/usr/local/libexec/sftp-server" is enable and the path is correct.

I don't know what is the problem even though I fallback the version to
3.4.1. The following is the sshd_config file:

Port 22
Protocol 2
#ListenAddress 0.0.0.0
#ListenAddress ::

# HostKey for protocol version 1
HostKey /usr/local/etc/ssh_host_key
# HostKeys for protocol version 2
HostKey /usr/local/etc/ssh_host_rsa_key
HostKey /usr/local/etc/ssh_host_dsa_key

# Lifetime and size of ephemeral version 1 server key
#KeyRegenerationInterval 3600
#ServerKeyBits 768

# Logging

# rhosts authentication should not be used

# Don't read the user's ~/.rhosts and ~/.shosts files
#IgnoreRhosts yes
# For this to work you will also need host keys in

s
#RhostsRSAAuthentication no
# similar for protocol version 2
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication
#IgnoreUserKnownHosts no

# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication yes

# Change to no to disable s/key passwords

# Kerberos options

# Set this to 'yes' to enable PAM keyboard-interactive authentication
# Warning: enabling this may bypass the setting of

Subsystem sftp /usr/local/libexec/sftp-server

Can you let me know the problem?
