Check to see if lftp is compiled for sftp support

  1. find where lftp is installed
    • type which lftp
      example output: /usr/local/bin/lftp
  2. 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)
      libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0xb7e58000)
      libreadline.so.5 => /lib/libreadline.so.5 (0xb7e28000)
      libutil.so.1 => /lib/libutil.so.1 (0xb7e24000)
      libncurses.so.5 => /lib/libncurses.so.5 (0xb7de2000)
      libresolv.so.2 => /lib/libresolv.so.2 (0xb7dd0000)
      libdl.so.2 => /lib/libdl.so.2 (0xb7dcb000)
      libm.so.6 => /lib/tls/libm.so.6 (0xb7da8000)
      libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/3.4.6/libgcc_s.so.1 (0xb7d9f000)
      libc.so.6 => /lib/tls/libc.so.6 (0xb7c88000)
      /lib/ld-linux.so.2 (0xb7fbc000)
  3. 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
