As of version 1.8.0, yule can be build with support for libwrap, i.e. Wietse Venema's tcp wrappers libraries. To enable this, use the configure option --with-libwrap.
You can then restrict access to yule with appropriate entries in the /etc/hosts.allow and/or /etc/hosts.deny files.

If you use the configure option --enable-install-name=NAME, then yule will be installed as 'NAME', and this is what you then need to use as the daemons name in the /etc/hosts.allow and/or /etc/hosts.deny files. |
