lonely written words—are all you’ve got”

—Virginia Shea

“communication happens when I know you know what I know”


God only knows what's going on with 12

Engineers dig deep in the tomes of man pages to search for knowledge. We grow wiser as we pore over ancient wisdom left by past scholars. Sometimes we find they were scratching their heads much as we do now.

man traceroute

Note that the gateways 12, 14, 15, 16 & 17 hops away either don’t send ICMP “time exceeded” messages or send them with a ttl too small to reach us. 14 – 17 are running the MIT C Gateway code that doesn’t send “time exceeded”s. God only knows what’s going on with 12.

I was searching for an option in the traceroute command and found mention of hops that don’t respond. Apparently, we may have to dig into other texts to answer some of life’s more challenging technological questions.
