Greetings gentlefolks
I thought as a part of my further education I'd try installing an axip link
on a system based on a Redhat 6.1 system with a 2.2.12 kernel, ax25 packages
lib-0.0.7, app-0.0.4, tools-0.0.5, node-0.3.0.
I'm confused by the documentation so I thought I'd ask the questions here so
that Jeff Tranter can wrap up the answers (assuming you good people have
some) in the next update to the ax25 howto.
1. axports entry
1.1 How come none of the examples have no window size (unless the window is
extracted from the string axip somehow)
1.2 Is the callsign associated with the axip entry a source or destination
callsign. Is that what the other end of the IP link will see as the
originator or is it the AX25 callsign of the other end of the axip link.
Maybe its just a placeholder. How is that callsign used by someone making an
ax25 call within earshot of this node.
2. ax25ipd.conf
2.1 Having said that the tnc and digipeater modes differ, how does the
digipeat mode work.
2.2 Loglevel 2 would appear to contradict the statement that logging doesn't
work (one line above it)
2.3 I'm using an 8 port TNC - does that mean I need 8 optional callsigns in
the mycall section (since a dual port TNC requires 2 calls)
2.4 The broadcast section is commented out in all examples I've seen - does
this mean it doesn't actually work?
2.5 Having declared a pseudo tty, the speed is then set - what is the point
in setting the speed of a non-existant physical device thats running at
multi-megabits/sec?
3. user interface
3.1 How does a dumb user access an axip link - does he have to connect to
the box and rummage through the ports list to find the axip entry and then
make a call using that as the port?
3.2 Is there a way of using a broadcast to notify local uses of what is
available at the other end of the axip link (assuming they can use it
directly somehow) - its not clear which direction the broadcast goes - down
the hole or out locally.
Sorry to play the "devils advocate" on these questions but here in the UK we
are starting to see a rise in the cost of Internet access which may bring a
few people back to packet. I'd like to be ready for them (and their
questions!!)
