Charlie,
sorry to bother you once more, but I'm again in troubles with my FastPath.
Before describing the problems I'm having I would like to check whether
my general understandings about AppleTalk IP networking are right.
That's why I'm copying this message to the list.
1- Kinetics and KIP from info-mac uses the same hardware (Kinetics FastPath)
and same PROM software but the downloaded software is different.
2- The main differences are about routing mechanisms:
a) Kinetics can use two methods: Appletalk as a subnet of an already
estabilished IP network (class A, B or C) or Appletalk as a distinct
(class A, B or C (?)) network reachable via fixed routing.
KIP manages Appletalk as a range of addresses into the address
range of an already estabilished IP network (any class?). The
range starts from the IP address assigned to the gateway.
b) Kinetics computes the AppleTalk net number from the IP net number.
KIP wants a Unix admin host which has the address mapping table.
c) Kinetics has no way to dynamically assign IP addresses. It eventually
leaves to the host the task of relying on the already existing Appletalk
node number assignment mechanism and using the node number as the
Ip host number.
KIP has a way to dinamically assign IP addresses on request.
The gateway (?) chooses an address in a predefined range and tries
to maintain the node number - host number correspondence.
3) MAC/IP telnet uses the KIP method asking the gateway for an IP number
4) NCSA Telnet doesn't use the KIP method (BTW has it a name?). It can
use either a fixed IP address or use the Appletalk node number as
the IP host number.
Now let me describe the problem I'm having. Attached to this message you can
find some background information about my network environment (net map and
cofiguration files).
I finally received the latest (?) PROM from my local Kinetics dealer in
a package called "The FastPath Upgrade Kit". It included
-PROM release 3.0
-FastPath Manager v2.1
-new gateway code
-new AppleTalk utilities (Look and Echo)
I also received a Bulletin containing a suggested hardware mod called
"Noise Immunity Modification Procedure".
I installed the new PROM. I did not apply the hardware mod.
I was then able to "Find" the gateway. I loaded it with the at-gw.srec file
got from info-mac (sumex-aim) and the config file attached below.
I started the atalkad daemon on the KIP admin host called fdt (a Sun 3/50
running SunOs 3.2).
I succeded in pinging the gateway from fdt.
I then tried to run NCSA Telnet from a MacSE. I chose the IP address
192.12.192.221 (in the "ipstatic" range). I tried to connect to fdt
I got the message "Couldn't connect to fdt".
I tried to run Mac/IP telnet. After a long time it said "A fatal error
happened! The program will die. Cannot obtain an IP address from server".
At that point I suspected that something was wrong with the configuration.
I tried to "Find" the gateway to RESET and reload it but...
THE SAME OLD STORY HAPPENED. I wasn't any more able to "Find" it.
I tried the procedure "Power cycle, wait 5 seconds, Find" many times with
no result.
Ah, I can still ping the gateway from fdt.
What happened, what can I do now?
Thanks in advance. Ciao
