View 7 Replies View Relatedcan we block email address in a way that a user cannot login into multiple systems simultaneously, so that if a user logs in into a system (with ip address 192.168.1.22)and if he tries to login to into another system at the same time(with ip address 10.0.0.5) his previous system(i.e 192.168.1.22) has to logout automatically. Is there any predefined scripts for this.

I'm having windows 7 on virtualbox too and they can ping each other and the webserver on debian (apache2) is working fine. The problem is i can't get squid to block webpages. I have the correct settings on windows proxy settings, but i'm not so sure about squid. I want to block lets say www . xxx. com for example. So I add to the main configuration file:

View 5 Replies View RelatedI've been all around the net and can't find a "simple" answer how to block our LAN users from downloading torrents. Is it really that difficult?
Here's our setup:
1. The Server's Configs:
2. sudo gedit /etc/squid/squid.conf
3. sudo gedit /etc/rc.local (to start Firewall rules on bootup)
4. Server NOT a DHCP Server
5. No other iptables rules are configured, just the above ones.
Before in a 1 NIC setup, I blocked Workstations MAC addresses in the Router + Squid Proxy Server (Not Transparent), it worked, but some Online Java Apps didn't work and users can't send/receive email so I abandoned the method.
Now, I installed transparent Squid Proxy with 2 NIC cards, it works, but workstations can still download torrents! I know Squid doesn't block ports, right? So the answer must lie in Iptables Firewall? I basically use Squid just to deny access to Facebook, Friendster, or other "unproductive sites".

How to block torrent downloading by using a Firewall? Or is there another "simple" way?
I've heard that it's better just to allow regular ports (80, 22, 465, etc...) then block all the rest, this way, you can prevent unnecessary ports.
I'm not an Iptables/Firewall expert so can you pls. explain it a bit more detailed if that's the case.
I'm also aware of just telling our users NOT to download torrents, but I just want to prohibit it entirely.
I know I will be the most "uncool" employee in our office.

View 7 Replies View RelatedI get assigned an IP from the university's server. Every now and then, a student will plug in his router to the network trying to get wifi in his/her room.
And by doing so will start assigning IPs on the network, while rendering useless the university dhcp server, which has to cope with a higher number of pc's.
How can I specify to dhclient (or the linux system in general) NOT TO obtain IP addresses given by a specific mac address ?
I want to block some ip address that are attacking my server and making my ssh port busy. On searching the google, I found
Code:
iptables -A INPUT -s ip_address -j DROP
I will add this rule in iptables. My questions are:
1) do I have to do
Code:
chkconfig iptables on
so that it load the iptables at boot. I am wondering why do I need this because iptables is already modified and it loads the iptables at boot time if firewall is enabled.
2) When we add the above rule, which file is modified? Another way, where are this rules stored? It is not in /etc/sysconfig/iptables and /etc/sysconfig/iptables_config.
