I have been asked to stop staff using MSN messenger. I believe the easiest way to do this is to block access to https://login.passport.com therefore stopping anyone to log on. (dont want to start blocking ports)
I guess I would add this address somewhere to our firewall (the person in charge of our firewall has just left !) any ideas how I can do this.
Whats your firewall name,
Please provide as much info as possible
Firewall is the one that comes with Red Hat linux 7.2
Im not a pro at setting firewall under linux, but here's something that might work
Get IPTABLES working.
This can block an ip or range of ips:
iptables -A OUTPUT -p tcp -d messenger.hotmal.com --dport 1863 -j REJECT
iptables -A OUTPUT -p tcp -s address/mask -d messenger.hotmal.com --dport
1863 -j REJECT
also if a real security admin could have a look at this, there may be a flaw in this...
