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 additionalpassword, 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.
