# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# The Inovis EDI VAN requires Passive connections:
ftp.put_Passive(True)

# Note: The Inovis documentation mentions an outbound
# high port range of 40000-49999.  In passive mode, the
# FTP server chooses the port number for the data
# connection.  The Inovis server will choose a port number
# in the range 40000-49999.  To establish the data connection,
# your firewall must allow outgoing connections in that port
# range. 

# This tells Chilkat FTP2 to establish
# an AUTH TLS secure channel after connecting
# on the standard FTP port 21.
ftp.put_AuthTls(True)

# You'll probably need this property set to True if you're
# behind a NAT router or firewall.
ftp.put_PassiveUseHostAddr(True)

# The Ssl property is for establishing an implicit SSL connection
# on port 990.  Do not set it to True.  The Inovis VAN
# uses explicit encryption (SSL/TLS).
ftp.put_Ssl(False)

# The Chilkat FTP component automatically sends a "FEAT";
# command after connecting.  This allows the component
# to better know the FTP server's capabilities.
# The Invois server doesn't recognize the FEAT command,
# so disable it:
ftp.put_AutoFeat(False)

# Connect, convert to TLS, and login to the FTP server.
success = ftp.Connect()
if (success != True):
    print(ftp.lastErrorText())
    sys.exit()
else:
    # LastErrorText contains information even when
    # successful. This allows you to visually verify
    # that the secure connection actually occurred.
    print(ftp.lastErrorText())

print("Connection to Inovis EDI VAN OK!")

# Do whatever you're doing to do ...
# upload files, download files, etc...
