Just so you know dpup is a beta puppy linux, with the lenny debian repos in it. Sorta, it is beta.

My problem is what firewall is puppy running? iptables?

I ran the firewall script and asked it to auto configure.

then ran nmap -v -A 192.168.1.6

and it told me port 22 was open (ftp)

nothing else

so reran script and asked to open port 3389, and it was the same Sad

if it is iptables then it's easy to open the port.

is there guarddog or firestarter for puppy?

iptables is not a firewall. iptables is a user-space application that allows one to configure the kernel-space rule-set of the the netfilter kernel module. A collection of rules composed and organized in such a way that they control network traffic into, out of, and through a host can be a firewall (or router). When you run iptables, it requires some arguments to modify or display the rule-set in the kernel module. Often, the sequence of iptables commands that creates a coordinated set of rules is encapsulated into a shell script, and this is often thought of as a firewall. The rules in the firewall script need to be composed in a way that creates a firewall suitable for the application. Sometimes the sequence of iptables commands is generated by a GUI tool, such as the ones you mentioned. If the firewall script you are using is not satisfactory, you can modify it. You can also modify the rules on-the-fly, using discrete iptables commands to add/delete/modify specific rules.

Port 22 is not normally FTP; it is SSH (FTP uses port 21). The whole concept of ports being 'open' is a misleading use of the term, in my opinion. A port can be thought of as 'open' if either of two things are true: an application or service is listening for incoming traffic on the specified port, or if there is no firewall rule that blocks traffic into (or out of, perhaps) a particular port. An application or service may be listening on a port, but receiving no traffic, due to the upstream application of a netfilter rule. In this situation, the application will not know that it will receive no traffic.
