Package: ftp-ssl
Version: 0.17.12+0.2-6
When the ftp command supplied in the ftp-ssl package
is invoked with both the "-n" and the "-z secure"
switches, the "-z secure" switch has no effect. The
"AUTH SSL" command is not sent to the remote server
and no SSL negotiation takes place. Use of the "-n"
switch is essential if one wishes to use standard
input redirection to supply the "user" command, WITH
A PASSWORD, in a file. Use of the "-z secure" option
is essential to connect with a server which requires
an SSL-secured connection. Since the two options do
not work together, it is impossible to write a script
to automate file transfers using this client when
connecting to a secure server.
Here's an example. The file "test.ftp" contains the
following lines:
open my.mouse.hole 991
user mouse cheese
dir
close
quit
If the following command is issued:
ftp -pinegvdz secure < test.ftp
the following output is received:
Connected to my.mouse.hole.
220-Glub Tech Secure FTP Wrapper (v2.5.7)
220 my.mouse.hole FTP server (Version wu-2.6.2(1) Mon
Aug 16 17:10:57 IDT 2004) ready.
ftp: setsockopt: Bad file descriptor
---> SYST
530 Please login with USER and PASS.
---> USER mouse
503 Login with AUTH SSL/TLS first.
Login failed.
ftp: setsockopt (ignored): Permission denied
---> PASV
530 Please login with USER and PASS.
Passive mode refused.
---> QUIT
221 Goodbye.
If you leave off "-z secure" and connect to a
non-secure ftp server, this technique works fine. For
example:
ftp -pinegvd < test.ftp
produces the following output:
Connected to my.mouse.hole.
