This is linux-ftpd-0.17 for Linux, a port of the OpenBSD ftp daemon.
This package updates linux-ftpd-0.16.
If you're reading this off a CD, go right away and check the net
archives for later versions and security fixes. As of this writing the
home site for NetKit is
ftpd Daemon for the ftp protocol.
Working compiler, libc, and kernel.
Supports shadow passwords. Does not (yet) support PAM.
This version contains vital fixes for a remotely exploitable
hole relating to printf format string processing.
linux-ftpd-0.16 and earlier should not be used.
This version does not put ftp users in utmp; the utmp code is
#if'd out. This means the -U option does not work.
Keep in mind that the man page has not been completely edited
for Linux and may refer to a few BSDisms.

including the files
extern.h ftpcmd.y ftpd.8 ftpd.c
logutmp.c logwtmp.c pathnames.h popen.c
These came from src/libexec/ftpd.
The support files came from various sources, including
OpenBSD's libc, NetKit 0.09, and sendmail 8.7.4. (8.7.4
because it was handy, not for any particular reason.) Others
were written for this port.
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.
If you get gcc warnings from files in /usr/include, they are
due to problems in your libc, not netkit. (You may only see
them when compiling netkit because netkit turns on a lot of
The DEC compiler for the Alpha is now freely available. This
is a much better compiler with gcc, that is, it generates much
better code. If you have the DEC compiler, you can explicitly
use the DEC compiler instead of gcc by configuring like this:
It is known to generate spurious warnings on some files. Also,
some headers from some versions of glibc confuse it; that may
prevent netkit from working. Other problems should be reported
Send bug reports and whatnot to the netkit bug address, not to
OpenBSD, as the OpenBSD organization doesn't have anything
official to do with this port. Things will be forwarded if
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
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 to the netkit address.
Postings to netnews or mailing lists will not be seen due to the
enormous volume. Also, anything that doesn't get filed in the bug
database is quite likely to end up forgotten.
Please don't report known bugs (see the BUGS file(s)) unless you
are including fixes. :-)
Mail should be sent to: email@example.com
Early in April 2000, a hacker broke into the machine that was hosting
the netkit bug database for me and trashed it. Unfortunately, it seems
backups hadn't gotten done for a while, so three months of mail (since
mid-January) was lost. So, if you sent something and didn't hear back,
or you sent something, heard back, but the changes failed to appear in
this release (unlikely but possible) - please resend.
Please see http://www.hcs.harvard.edu/~dholland/computers/netkit.html
if you are curious why it was so long between the 0.10 and 0.16 releases.
Future plans for netkit maintenance are still up in the air, but in the
meantime new releases will still appear from time to time. I don't have
a whole lot of cycles to spare to work on netkit, so things are likely
to continue to be fairly slow.
