I wrote a fun sed script today: sed -E -n -e ‘:t ; s/(.{21})(.*)/\\bf\{\1\}\n\2/ ; p ; s/\\bf\{(.*)\}\n.*/\1/ ; h ; :q { n ; G ; s/(.{21})(.*)\n\1/\2/ ; tp ; s/(.+)\n.*/\1/ ; bt} ; :p { P ; bq }’ Short, but effective. Can you figure out what it does? (solution after the break)

dnsextd, TCP, and IPv6

I guess the dnsextd code must date back to PowerPC, because it had an extra ntoh call which on little-endian systems would cause TCP requests to fail. It’s fixed in the “tcp” branch of my git [...]
