I found Allowing/Unblocking Skype with Squid post at
http://www.squid-cache.org/mail-archive/squid-users/200606/0099.html.
Next steps are mentioned to block skype:
acl CONNECT method CONNECT
acl skype url_regex ^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+
deny_info ERR_CLIENT_HTTPS2IP_DENIED skype
http_access deny CONNECT skype
BUT this don't work for us.
When changes are applied (squid -k reconfigure) we get:
squid: ERROR: Could not send signal to x to process wxyz: (3) No such
process
If we rollback changes squid works fine.
Any response will be appreciated,
Jaime
