Call back or dial-in?

A call-back password is usually a modem feature- the more
expensive Multitech's have call-back passwords and numbers
stored in internal registers.  That's (IMHO) really the
easiest way to do it- it's transparent to the OS- you just
configure an ordinary dial-in setup; getty never even knows
anything strange has happened.

You can do callback with "ct" but it's much more of a pain.

If it's dial-up passwords you want, you do that by editing
/etc/d_passwd to be sure that the shell your dial-in users
will be using is listed (only /bin/sh and uucico are listed
by default).  You assign the passwd by doing

passwd -m sh (or ksh or csh or each in turn).

Finally, in /etc/dialups (it doesn't exist; you create it),
add the device that you want protected: /dev/tty2A

Note that this doesn't really have anything to do with
dial-up: you could list /dev/tty08 in there and be
challenged when you try to login on alt-F8 - in fact, that's
an easy way to check that you did it all correctly.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
