SafeTP on UNIX

How to get SafeTP (Server & Client) for UNIX:

• If you're in the UC Berkeley CS department, and have access to sww:
  the UNIX SafeTP binaries are located in /usr/sww/pkg/safetp for any machine that mounts sww.
  
  
• If you're elsewhere, download the UNIX source code:
  You need the following components to build the SafeTP UNIX binaries:
  
  • GNU Multi-Precision Library, version 3.1. (SafeTP also works with gmp-2.0.2; 3.1 is somewhat faster. See swox.com/gmp for even later versions, which should also be compatible.)
  • SafeTP UNIX source code, version 1.50, released Aug. 9 2003.
    If you are using gcc 3.4.1 or later, you will need this patch.

  You'll also need these tools (try ftp.gnu.org):

  • C++ compiler, such as g++.   egcs-1.1.2, gcc-2.95.x and gcc-3.x are known to work.
  • GNU Make (for "%.o : %.cpp" syntax).
  • Perl version 5 or later (for the install script).
  • Assorted unix utilities (sh, cp, rm..) ...

Patches

• This patch fixes a problem so the sources will compile under gcc-3.4.1 and later.
• This patch lets you specify a file with usernames and IP addresses, and restricts access accordingly. Also see the README.
• This script is someone's attempt to get sftpc to be usable noninteractively. Caveat emptor.

(Info on xinetd has been moved down into Documentation.)

• 1.46
• 1.40
• 1.45

Documentation for Unix tools:

Under Unix the SafeTP client (sftpc) is a stand-alone FTP client, and can be used as a drop-in replacement for the standard command-line client ftp.

sftpd, the Unix server, works in conjunction with a system's existing FTP server daemon (ftpd). sftpd provides confidentiality and server authentication via encryption, and ftpd provides user authentication via (for example) usernames and passwords.

Supported Platforms

SafeTP should run on any Unix system with a sockets library, inetd, and an existing FTP server.

SafeTP is known to work on these platforms (the processor/version in parentheses are the particular instances that have been tested; it probably works with other combinations as well):

• HP-UX (pa-risc/10.20) (add'l instructions for HP-UX 11i)
• Solaris (sparc/2.6, sparc/2.7, sparc/2.8, x86/(?))
• Linux (x86/2.0, x86/2.2, x86/2.4)
• DEC OSF (alpha/(?))
• FreeBSD (x86/4.1)
• OpenBSD (x85/(?))
• Irix (?/?)
• AIX (4.2.1.0/(?)) (see these instructions)

The configure script may work on other platforms too. If your platform isn't listed above, but you find it works (or doesn't!), drop me a line.

Porting SafeTP to new systems should be relatively easy. Please send me (smcpeak@cs.berkeley.edu) any changes you find necessary.

Contacting the authors

Comments about SafeTP as a whole, including the protocol, should be sent to both Dan Bonachea and Scott McPeak.

Comments specific to the Unix implementation (sftpc/sftpd), or the Unix-oriented web pages, should be directed to Scott.
