Since I have a terrible memory for which phone number goes to which
database and which login name goes with which password I made a
crutch. dialup allows a user to remember only the service name.
It then looks in a simple database in the user's home directory for
the dialing information and places the call via cu(1). It will also
list the login name and password for the service unless supressed
with the '-s' option.
Enjoy,

X.SH DESCRIPTION
X.B Dialup
Xuses a simple database setup in the user's home directory to help users
Xwho call other computers via cu(1). This database contains the mnuemonic
Xname of the database for reference. It also contains the phone number,
Xbaud rate and description and optionally the user's login name and
Xpassword for that service.
X.PP
XIf the
X.B -s
Xoption is used the login name and password are not printed.
X.PP
XThe database consists of six fields seperated by colons (:) much like
X/etc/passwd. The fields in order are: name, phone number, baud rate,
Xlogin name, password and description.

The "dialup" program posted to net.sources stores unencrypted passwords for other systems in the user's home directory. As a systems admin, I consider this a major security problem (relying as it does ONLY on Unix file protection to maintain confidentiality). I would not allow this program on my systems!
