Hello,
First off, I should mention that I am not a regular reader of this
group and that I am sending this from a friend's account (I haven't any
news :-( ). Please send any replies directly to me (kinley@crim.ca).
What do we have?
We have a localtalk network, an ethernet, and Kinetics Fastpath 4 on
which we are running KStar 8.0 in ethertalk1 and KStar-IP modes.
Pacerlink users are able to connect to our VAX VMS running the
Pacerlink software, and NCSA Telnet users are able to connect to UNIX
machines (the Kinetics box seems to be configured correctly).
Why am I coming to you?
I have been unable to get the Pacerlink software on the MACs to talk to
any UNIX host. Telephone calls to the `vendor's technical support` have
left me frustrated and no further ahead. It is not my intention to
badmouth the `vendor's techies`, I understand that support for the IP
family of protocols is somewhat new to this product.
and so...
Can someone answer these simple questions?
1. Does a MAC running Pacerlink 5.2b over an IP connection talk
TELNET or some other proprietary Pacer protocol?
IF PROPRIETARY (as the tech support claims)
2. The installation document and the tech support seem to think
that the mere presence of the pacerlink software on a disk is
sufficient to receive this `proprietary pacer protocol`
connection. How is the required daemon to be run (parameters,
port number, inetd.conf entry, any other usefull information)?
ELSE (telnet - my belief).
2. My Kinetics box seems to be working correctly, I see arps and
tcp packets from both the MAC and the UNIX host to which I
am trying to connect (my Kinetics box is in the hosts and
ethers file). The MAC however seems to be impatient, it sends
anywhere from 3-6 tcp packets to the UNIX host before the UNIX
host sends it 1. By time the UNIX box even sends out a 2nd or
3rd packet, the MAC gives up, and the UNIX host continues to
send another 1 or 2 packets every ~30 sec. Can it be that the
UNIX box is not answering quickly enough? Is there a way to
tell the Pacer software to be more patient? Packets that pass
between MAC and UNIX host use some weird port number on the
MAC side 50??? (but changes when the MAC IP address changes)
and the TELNET port. Is this normal?
Any help, comments, or experiences would be greatly appreciated. Again,
please send replies directly to me (kinley@crim.ca). If people express
an interest, I will summarized and post any responses.
Thanks in advance,
