First question for a long time :-) Everything works as I want, I have no problems in writing or implementing rules, but have a question:
iptables v1.2.3 (o.k., an old one but it does what I want), kernel
2.4.16. All Netfilter modules that I think I'll need are compiled into
the kernel, others are compiled as loadable modules.
I'm using conntrack and state for FTP, 'netstat -tupan' during a
download shows both ports 20 and 21 in use by the ftp server on the
Internet.
sunsite.dk in Aalborg, Denmark, is for me a better bet for Open Source
software than American sites and mirrors most of what I want. All the
stuff is logically organised and easy to find on the server.
When I do a directory listing, sunsite.dk ("Welcome to PureFTPd 1.0.10",
twin SPARC Sun Enterprise E3500) tries to open an LS connection from
ports 2 & 3. O.k., so I open high ports for established connections and
all works well.
My question is: What are ports 2 & 3 on the FTP server for? Why would
PureFTPD want to use ports 2 & 3? They're not listed in /etc/services
