Thanks for pointing that out. I am running stable and get this:
# ipchains --version
ipchains 1.3.4, 19-May-1998
You must be running potato, and that must be one of the differences
between version 1.3.4 and 1.3.8 of ipchains, as it doesn't like this
# ipchains -A input --destination-port 20 -j ACCEPT
ipchains: Unknown option `--destination-port'
Try `ipchains -h' for more information.
However, I think this would be equivalent:
# ipchains -A input -d 0/0 20 -j ACCEPT
