Sympathy. I'm very experienced in some things and still have trouble
with the simple parts now and then. Something about being too obvious to
see.

Guess: you are refering to hosts by NAME rather than IP NUMBER,
and you have no Domain Name Server facility on the net to translate between
them. MS-DOS Kermit uses no "hosts" file; it does use DNS facilities.
If you are totally isolated from the IP world then you can run "named" on
the Linux box to perform DNS. Otherwise use the nameservers provided by
your Internet connection agency.
Finally, recall that MS-DOS Kermit (and C Kermit) have nifty
string stubsititution variables and macros so that you can say
FOO
at the command prompt and have macro FOO hold
Set Port TCP 111.222.123.212, Connect
or whatever. That does the IP stuff by number yet saves you typing. It's
in the manual.

The two lines below are unnecessary. BIND is an abiguity resolver
and there are no alternatives below to choose amongst.

Looks fine.

IPXODI is Novell's IPX protocol stack. It uses IPX packets (how
could we tell?) and not IP. Thus the protocol number of 8137 is proper.
IPXODI isn't needed unless you wish to use IPX packets. And yes, ODI is
a good choice for a board handler.
Keep in mind that some builds of Linux have reported ARP cache
problems. I don't run Linux so I cannot provide details. But keep an
eye peeled.
