Hello TJ,
I tried the below configuration in my proftpd.conf file.
<IfModule mod_sftp.c>
<VirtualHost 127.0.0.1>
SFTPEngine on
SFTPLog /etc/proftpd/sftp/sftp.log
# Configure the server to listen on the normal SSH2 port, port 22
Port 22
# Configure the RSA, DSA, and ECDSA host keys, using the same host key
# files that OpenSSH uses.
# SFTPHostKey /etc/ssh_host_rsa_key
# SFTPHostKey /etc/ssh_host_dsa_key
# SFTPHostKey /etc/ssh_host_ecdsa_key
# Configure the file used for comparing authorized public keys of
users.
# SFTPAuthorizedUserKeys file:~/.sftp/authorized_keys
# Enable compression
# SFTPCompression delayed
# Allow the same number of authentication attempts as OpenSSH.
#
# It is recommended that you explicitly configure MaxLoginAttempts
# for your SSH2/SFTP instance to be higher than the normal
# MaxLoginAttempts value for FTP, as there are more ways to
authenticate
# using SSH2.
MaxLoginAttempts 6
</VirtualHost>
</IfModule>
#<IfModule mod_sftp.c>
*And got the below error while trying to do sftp. Can you please let me
know if I am missing anything?*
*sbaby@ubuntu:~/proftpd/proftpd-1.3.4b$ sftp sbaby@127.0.0.1
<sbaby@127.0.0.1>Connecting to 127.0.0.1...*
*ssh_exchange_identification: Connection closed by remote host*
*Couldn't read packet: Connection reset by peer*
*Regards*
*Simon*
