Is there any FTP server/directive for limiting login to only a certain time? Like only anonymous access in the morning? Or do I always I have enable/disable?

Thanks,

Peter

If you are using proftpd (http://www.proftpd.org/) there's a module for doing this (http://www.castaglia.org/proftpd/modules/mod_time.html). I've never used it myself, though.

On Linux and PAM enabled FTP server, you can use PAM. You can also use PAM to do that on another service (e.g. telnet, ssh).

The available documentation is a big cryptic, but it is very complete: http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/pam-6.html#ss6.25
