# To use a SOCKS4 or SOCKS5 proxy, simply set the following
# properties prior to connecting:
# The SOCKS hostname may be a domain name or 
# IP address:
CkSFtp_put_SocksHostname $sftp "www.mysocksproxyserver.com"
CkSFtp_put_SocksPort $sftp 1080
CkSFtp_put_SocksUsername $sftp "myProxyLogin"
CkSFtp_put_SocksPassword $sftp "myProxyPassword"

# Set the SOCKS version to 4 or 5 based on the version
# of the SOCKS proxy server:
CkSFtp_put_SocksVersion $sftp 5

# Note: SOCKS4 servers only support usernames without passwords.
# SOCKS5 servers support full login/password authentication.

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
