ICMP packets pretty much always carry some data (even though it's not _strictly_ required). This data is what is padded when the user asks for a ping with a specific packet size (e…

https://rob.sh/postindex I write mainly about networking topics, either standards updates or open source projects. Infrequently at best.

Oh, it definitely is (re: SF being into neighbourhoods)! Cool project. Kudos on recognising “Fairmount” versus lobbing it in with Glen Park or Noe Valley. (I don’t /really/ have a …
