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 pass-
word to be used for dialup security for those users logging in to use that program. The third is commen-
tary, 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.
