UNIX for Dummies Questions & Answers

Hello,

For a time now I have this problem which I cannot solve and this bothers me cause it seems so simple.

I have to change an existing (ftp only)user to create a timeslot for this user. (e.g. he can only login between 8 and 10 PM).

Facts:
- I can only use a terminal client (no gui)
- I am using SunOs 5.6

I am not an Unix expert (yet) so if anyone can help me I would be verry thankfull.

I would try something like this:

Give the user a shell of /usr/local/bin/ksh8-10 by editing /etc/passwd.

Put /usr/local/bin/ksh8-10 in /etc/shells so the guy can still use ftp.

ln -s /usr/bin/false /usr/local/bin/ksh8-10
to insure that he can't login.

At 8 a cron job would "ln -s /usr/bin/ksh /usr/local/bin/ksh8-10" to allow logins for a while. But at 10 a cron job would set it back.

To be real complete, maybe a script at boot up time to set /usr/local/bin/ksh-8-10 based on current hour.
