Just FYI, I keep a little directory of network-related ports and a few tools here:
https://www.subspacefield.org/~travis/OpenBSD/ Notably, pf_dns_lookup is a short python program that looks up DNS names and puts them in a pf table for you. You can call it from a cron job to update rules for dynamic DNS entries. For example: pf_dns_lookup localhost dynamic_dns.name.tld | tee /etc/table.txt | pfctl -t table -T replace -f /dev/stdin This will store the table in /etc/table.txt too, so it can persist across reboots. IP addresses may be used as input, and that they will merely map to themselves. -- Good code works. Great code can't fail. -><- <URL:http://www.subspacefield.org/~travis/> For a good time on my UBE blacklist, email [EMAIL PROTECTED]
