asciilifeform: i'ma put a likbez in the l0gz, for fyootor folx : here's ordinary rs232, at ttl signal level, (noninverted), transmitting a 10000010 :
asciilifeform: ( nitpicker could reply : 'but what about isosynchronous usb mode ?' -- it's liquishit, unsupported by most interface ics you can get, and specifically disclaims any guarantee of packet delivery. used for, e.g., usb soundcard. )
asciilifeform: parallel port was adequate. but no recent boxes have'em and the usb paralleldongles never worked ( they were specific to printers, those have buffers, usb doesn't really give you realtime synchronism )
asciilifeform: http://btcbase.org/log/2017-10-19#1726711 << this is unknown in usa: too much high tech! instead, and only in earthquake states, and only in ~some~ towns, they issue... wrenches, with which one is expected to close the valve outside the ruins of your house, as you climb from the rubble☝︎
asciilifeform: and to know if uninvited guests have been inside the cage.
asciilifeform: i see it as worth something, to be able to immediately distinguish , e.g., a dead hdd, from a stolen hdd .
asciilifeform: http://btcbase.org/log/2017-10-19#1726680 << i'd like a republican chair to sit in too!111 switch, however, if you want GB or above -- does require making own silicon if you want it to meaningfully differ from the extant items . fpga won't cut it clockwise.☝︎
asciilifeform: http://btcbase.org/log/2017-10-19#1726675 << 'filter out the strange' is the naive usg av 'industry' nonsense. a half decent diddletron neither produces nor consumes any 'strange', and 'magic packet' will consist of , e.g., lubyization of 10,000 ordinary packets' timing☝︎☟︎
asciilifeform: ( want non public? is what crypto is for, switch is not a trusted piece of equip )
asciilifeform: or alternatively asciilifeform's philosophy -- i.e. packets that leave your nics, are to be considered public
asciilifeform: if you have a pair of racked boxes that gotta talk seeekritly to ~one another~, don't connect them via the switch, connect directly with crossover cable ( this is what the spare nics quality boxen ship with, are for )
asciilifeform: http://btcbase.org/log/2017-10-19#1726673 << that was what i didn't and still don't grasp : what exactly can enemy exfiltrate from a boobytrapped ~switch~ ( it ain't a firewall, it's a dumb switch) that he cannot get from his upstream tap ??☝︎☟︎
asciilifeform: i'll mass produce switches some time after doing same for ordinary dc power supplies, they rank ahead in seekritude☟︎
asciilifeform: i don't manufacture switches, BingoBoingo , and i have no intention of starting, it isn't a device that handles seekrits, and very literally either works or does not -- like mains cord.☟︎
