View 1 Replies View RelatedIn the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10

I need to block some websites and torrents on my LAN running on mostly WIndows XP pcs and a Windows 2008 domain controller. It's possible to block some sites using DNS in Windows Domain controller, but users have the rights to change DNS and bypass the rule. Editing HOSTS file doesn't workThen I tried using Avast antivirus Site Block feature, but that doesn't work on any browser except Mozilla. We have to use Epic and Mozilla Firefox.We can't use a dedicated hardware firewall due to budget constraints and the fact that we have multiple ADSL lines for internet. No single gateway.

Now my question is regarding skype calling. Since skype uses port 80, does it mean that it passes its request via proxy or direct and for safe side I've changed skype incoming port to 443 which squid does not see it. How much and width does skype use for calling in that case. Some one told me that it using squid to pass its request which I don't agree.

View 1 Replies View RelatedI have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.
I have a question which it believe it is quite simple but I have no clue how to do it... I'm using Fedora 12 and I'm the only Linux machine in my office's LAN... I have Apache (httpd) setup and my co-workers can access the sites perfectly by using my IP address, for example [URL]... So here's the question, how do I setup a domain name so everyone in the LAN can access the sites by typing [URL]..

I'm having some issues settings up a transparent proxy server, which should allow only regular web browsing (port 80), any other port (including HTTPS (443)) has to be blocked, as well as any other port. Right now, I'm using Debian 6 and Squid3. The server only has one NIC. The topology is like this:
Clients <-> Proxy Server + DHCP Server <-> Internet
With this setup, the network does have internet access and the websites I whitelisted are the only ones accesible via browser, however port block is not working, every port is open, hence why trying to access blacklisted websites through HTTPS is possible. Seems to me Squid3 is doing it's job fine, however IPTABLES for some reason seems to be redirecting all the trafic to port 3128 (Squid3 port). I could be wrong, but I've been unable to do anything related to ports with squid3 (either whitelisting or blacklisting).
For Iptables I used:
Code:
iptables -A PREROUTING -t nat -i eth0 -p tcp -j REDIRECT --dport 80 --to-port 3128
iptables -A INPUT -i eth0 -m tcp -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth0 -m tcp -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -i eth0 -m tcp -p tcp --dport 3128 -j ACCEPT
iptables -A INPUT -i eth0 -m tcp -p tcp --dport 443 -j DROP
Squid3 config:
Code:
acl manager proto cache_object
acl localhost src 127.0.0.1/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
acl Safe_ports port 80 # http
acl whitelist dstdomain "/etc/squid3/whitelist"
