I am new to Debian. I installed Etch on a Dell precision laptop. I use DHCP.
I have lots of questions, but I will start with this one: I created an iptables script that I downloaded, and set it up using # update-rc.d firewall.script defaults However, after doing this, I noticed that CUPS would not work. (It had been working well.) The firefox browser returned the message "The server at localhost is taking too long to respond." when I tried to connect to http://localhost:631. I also tried http://127.0.0.1:631, and it gave the same responce. I also could not ping localhost or 127.0.0.1. So I removed the firewall using # update-rc.d -f firewall.script remove and rebooted. Now, when I run # iptables -L I get Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination *However, I still can't access CUPS or ping localhost.* What might be wrong? Where do I start to look? John
