     Most UNIX systems are capable of communicating with other
UNIX systems through a series of programs called uucp. Once on a
UNIX system, type ls/usr/lib/uucp to list the support files
stored in conjunction with the uucp programs.

     The two most important files in this area (from a hackers
point-of-view) are L.sys and L-dialcodes. It is in these files
that the UNIX system stores the numbers AND passwords to other
UNIX systems!

     The first file (L.sys) contains:

(1) The name of the remote system

(2) The time that the first UNIX system should call

(3) The hardwired device that should be used for the call (i.e.
modem port #)

(4) The baud rate

(5) The phone number

(6) The logon information

     For example, the file might look like:

MaBell MoTu tty99 300 dc2638 login uucp ssword: it

     In the example, the system called MaBell can be called on
Monday or Tuesday. You can probably call any time you want,
though. The UNIX system is to dial it through device tty99. The
number is dc2638. It will then wait for the string 'login' and
send uucp (the username), it will then wait for the string
'ssword:' and send the password (it).

     As you may have noticed, the phone number (dc2638) is
non-standard. This is because the system can use abbreviations
from the 'L-dialcodes' file. A typical file might look like:

tn 9w18005218400w12345678w
dc 311555-

     In this case dc2638 is really 311-555-2638. Also, some
extenders may be thrown in the file! The 'w' means wait for
dialtone.

     To list these files you wouls type:

cat /usr/lib/uucp/L.sys
cat /usr/lib/uucp/L-dialcodes

     In most cases, these files are protected, but intelligence
is not a prerequisite for UNIX administrators! Although, this
should be no problem if you logon as (gasp!) the super-user
(alias 'root').

     Unfortunately, the uucp password does not run under the
nowmal UNIX shell. It uses a separate protocol.

     If you are successful in obtaining these files, you will
have to expanded your directory of UNIX systems, passwords, and
possibly even SCC's and WATTS extenders! If you master the uucp
protocol, you can copy ANY file! Once on other systems, this
could work in a vicious cycle [viscious for THEM (that is)].
