find where lftp is installed
- type which lftp
  example output: /usr/local/bin/lftp
Check linked libraries
- Execute: ldd /usr/local/bin/lftp
- Example output:
  linux-gate.so.1 => (0xffffe000)
  
  libexpat.so.0 => /usr/lib/libexpat.so.0 (0xb7f8e000)
  
  libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0xb7f5c000)

To use sftp with lftp
- libssl must show like above.
  libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0xb7f5c000)
- the version and other info does not need to be the same but libssl must appear
  - if libssl is not listed.
    1. install SSL (sudo apt-get install libssl-dev)
    2. recompile lftp with ssl support

./configure --with-openssl=/usr/lib

Basic usage is:
- lftp sftp://[domain name]
- lftp sftp://theURL.org
For a different user name than the one you are currently using
- lftp sftp://[user name]@[domain name]
- lftp sftp://userName@theURL.org
for a different port and different user name
- lftp sftp://[user name]@[domain name]:[port number]
- lftp sftp://userName@theURL.org:8002
