ftp源码

This is netkit-ftp-0.16.

This package updates netkit-ftp-0.10.

If you're reading this off a CD, go right away and check the net
archives for later versions and security fixes.

Contents:
	ftp		Client program for the ftp protocol.
	
Requires:
	Working compiler, libc, and kernel. 

	libreadline (GNU readline library) is optional but recommended.
	If you use it, you will need a recent ncurses or libtermcap as
	well.

Security:
	This client contains a fix for a buffer problem in passive mode
	handling. 

	It also containts some somewhat-kludgy fixes for problems that
	can arise doing mget from a hostile or compromised ftp server.

	Consequently, earlier versions should not be used.

Note:
	To compile ftp with readline support you'll need a copy of the
	readline library installed. If you don't have it, get
	readline-2.0 (or higher) from ftp.gnu.org. You'll probably
	need to apply the enclosed patch, or ftp will have problems with
	^C handling.

Installation:
	Patch your readline library if necessary.

	Do "./configure --help" and decide what options you want. The
	defaults should be suitable for most Linux systems. Then run
	the configure script.

	Do "make" to compile.
	Then (as root) do "make install".

	Save a backup copy of any mission-critical program in case the
	new one doesn't work, and so forth. We warned you.

DEC Alpha:
        Compaq were kind enought to make available their C compiler for
        the Alpha, you can down load this for free from
        http://www.unix.digital.com/linux (At time of document 25/11/1999)
        this package has been compiled and tested with this compiler as
        with the GNU compiler. To compile this from source simply issue
                CC=ccc ./configure

Bugs:
	Please make sure the header files in /usr/include match the
	libc version installed in /lib and /usr/lib. If you have weird
	problems this is the most likely culprit.

	Also, before reporting a bug, be sure you're working with the
	latest version.

	If something doesn't compile for you, fix it and send diffs.
	If you can't, send the compiler's error output.

	If it compiles but doesn't work, send as complete a bug report as 
	you can. Patches and fixes are welcome, as long as you describe 
	adequately what they're supposed to fix. Please, one patch per
	distinct fix. Please do NOT send the whole archive back or
	reindent the source.

	Be sure to send all correspondence in e-mail. Postings to netnews 
	will not be seen due to the enormous volume.

	Please don't report known bugs (see the BUGS file(s)) unless you
	are including fixes. :-)

	Mail should be sent to: [e-mail]

if you are curious why it's been so long since the last NetKit release.
(The short version is that I gave things to some other people, who let
them kind of slide.)

I do not currently plan to continue maintaining NetKit; I am doing this
release and perhaps one or two more, and then I intend to give the source
tree to Red Hat or some similar organization for long-term maintenance.
