I'm new to using Ubuntu OS and its interface and using terminal.
Recently I was trying to deploy
shorewall firewall. Even though shorewall is running I can't get through one command, i.e.
shorewall show connections
root@hassaan-OptiPlex-GX620:/usr/share/shorewall# shorewall show connections Shorewall 18.104.22.168 Connections (5 out of 63584) at hassaan-OptiPlex-GX620 - Thu Aug 29 14:33:36 PKT 2013 grep: /proc/net/nf_conntrack: No such file or directory"
I get this message.
Please help me with this problem.
By the way I am using this tutorial.
