I've got a friend who is refurbishing an Tektronics 4404 AI workstation from the 80s/90s. (You can find him on YouTube if interested.)
The box does have an ethernet adapter but the networking software, apart from having no manual, is obviously working on pre-1993 CIDR networking because classless networking was invented. i.e. it has classful networking.
I'm old enough to vaguely remember this in my college networking classes, but I've never worked on classful routing.
What we want to do is to give the box an address of 192.168.1.61 is in old money is a HOST address, which is OK and works.
We want to keep everything on the 192.168.1.x network local, I guess it shouldn't got to the router.
And everything else goes to the router on 192.168.1.1.
We have one networking table in colon separated format.
Assigning the HOST address is OK.
The other two parts we don't understand. Is it possible to say just to send out packets to 192.168.1.x to the interface, but everything else to the router?
With CIDR you have 0.0.0.0/0 -> 192.168.1.1 would be the way to do it, but pre-CIDR 0.0.0.0 seems to mean undefined rather then default.
It does kind of work with this so far:
192.168.1.1 # interface
64.0.0.0 -> 192.168.1.1
35.0.0.0 -> 192.168.1.1
which is kind of guessing but I think this leaves out a lot of routing and you would end up having to put in millions of individual static routes for each network and subnet. There has to be a better way!
Any help appreciated!
