This is a quite neat example, but it looks like the QNX shell mixed several concerns about how do you connect to these machines, how do you secure the communication, etc.
$ ssh @2 "cat /path/to/large/file" | ssh @3 "/bin/grep 'foo'" | ssh @4 "cat >/tmp/output"
is rather clunky, but separates those concerns well.
- spc476 11y agoSorry about not getting back sooner (returning from vacation) but the QNX network message passing ran over Ethernet, not IP, so it only worked (to my knowledge) over a local segment. Given that it was transparent to user processes, it could be argued that security could be added at that layer (two of the seven layer OSI model).
