Telmo, sorry for the late reply, but FOSDEM and work backlog kept me
away from the pc. :-)
You'll need to write blocked mac addresses to a file:
/etc/e-smith/templates-custom/etc/squid/squid.conf/20acl_95mac
using the following syntax:
acl computer1 arp 01:02:03:04:05:06
acl computer2 arp 01:02:03:04:05:06
substituting computerX with a name that let you understand who is
blocked and mac address.
Then add /etc/e-smith/templates/etc/squid/squid.conf/30http_access_05_deny_mac
containing:
http_access deny computer1
http_access deny computer2
Expand template to re-create squid.conf:
expand-template /etc/squid/squid.conf
Restart squid:
service squid restart

Ciao,
