Thanks Ian.
So I issue this command on both cluster nodes and it will also
stop access to the virtual cluster address?
What's the command to reverse / remove
" iptables -A INPUT -s 10.5.5.25 -j DROP " ?
" iptables -A INPUT -s 10.5.5.25 -j DROP " ?
Just in case there's a problem, I'll need to reverse.
Tks

Can someone provide me some examplecommands / syntax ?Source IP address : 10.5.5.25 (Windows server)Tcp port : 1521My Linux boxes IP address : 10.5.5.46 / .47My Linux cluster virtual addr : 10.5.5.45In fact I would like to block on all ports on the Linux cluster to stopthis Windows server from accessing it. So what's the exact commandsI should issue on each of the Linux box? Would iptables also blockthe Windows server from accessing the cluster virtual IP addr?ThanksU
