Hi

I want to block below daemons in tcp wrapper for testing purpose:
1.Samba should be accessiable by xyz.com domain but deny to all
2.Imap and pop3 only accessiable by abc.com domain and deny to all

Please note I'm using RHEL5 OS
so please suggest how could i do this.

Thanks & regards

True; in that case you use iptables for smbd : 139/tcp, 445/tcp and nmbd: 137/udp, 138/udp.
