Hosts.allow / deny

[nitin bansal]

Hi Duncan,
Your configuration should be as follows:--
 
host.deny
 
imapd : ALL EXCEPT 127.0.0.1
sshd :  ALL EXCEPT 10.10.10.2
smtp : ALL EXCEPT  10.10.10.3
 
and leave the host.allow blank.
 
Or the better case..u should use iptables....default firewaal for fedora... go through the following link to know iptable configuration :

ALLOW : imapd : 127.0.0.1
ALLOW : sshd : 10.10.10.2
ALLOW : smtp : 10.10.10.3
hosts.deny

i just want to allow access to imapd,sshd and my smarthost
Will this kill the DNS service etc .Suggestions welcome
.Firewall is too costly
