NAME
dialups, d_passwd - dialup security control
DESCRIPTION
dialups and d_passwd are used to control the dialup security feature of
login (see login(1)). If
/etc/dialups is present, the first word on each line is compared with the name of the line upon which
the login is being performed (including the
/dev/, as returned by ttyname() (see ttyname (3C)). If
the login is occurring on a line found in
dialups, dialup security is invoked. Anything after a space or
tab is ignored.
When dialup security is invoked,
login requests an additional password, and checks it against that
found in /etc/d_passwd
. The command name found in the ‘‘program to use as shell’’ field of
/etc/passwd is used to select the password to be used. Each entry in
d_passwd consists of three
fields, separated by colons. The first is the command name, matching an entry in
passwd. The second is
the encrypted password to be used for dialup security for those users logging in to use that program. The
third is commentary, but the second colon is required to delimit the end of the password. A null password
is designated with two adjacent colons. The entry for
/usr/bin/sh is used if no other entry matches
the command name taken from
passwd.
