Blocking Specific MAC & Blocking Multiple MAC

Blocking Specific MAC:

acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl bad_MAC arp 192.168.200.100/32
acl our_network src 192.168.200.0/24
http_access deny bad_MAC
http_access allow our_network
http_access deny all


Blocking Multiple MAC:

We could write down the MACs one by one separated with ‘spaces’. Or we could create a file (in this case /etc/squid/invalid_MAC_file) containing the MACs.

48:5B:39:0C:CE:10
00:1F:D0:63:A3:03

acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl invalid_MAC src 48:5B:39:0C:CE:10 00:1F:D0:63:A3:03
acl invalid_MAC src “/etc/squid/invalid_MAC_file”
acl our_network src 192.168.200.0/24
OR
http_access deny invalid_MAC
http_access allow our_network
http_access deny all

Postfix SASL authentication with SMTP port 465:

  By default postfix SMTP works on 25 port.   You can check this by following command with the output below: #netstat -nat tcp        0      0 0.0.0.0:25             0.0.0.0:*               LISTEN    Here we will change the port to 465 with SASL authentication. It is useful technique to fight against spam. Users those travel here and there with their laptops need not to change their e-mail client software settings also. Here is how we can do it.   Step 1 . Edit the file /etc/dovecot.conf and make sure your auth default section has the lines below. auth default { socket listen {   client {    path = /var/spool/postfix/private/auth    mode = 0660    user = postfix    group = postfix     }   }   mechanisms = plain login } Step 2 . Edit /etc/postfix/main.cf , find the keys below and change its values as follows or add it at the bottom of the file if the key (the word before the = sign) cannot be found. mynetworks = 127.0.0.0/8 smtpd_sasl_type
