NCSA Telnet 2.3: Questions and Diagnosis

I have a two problems regarding Telnet. I have been using Telnet rev 2.2 and recently upgraded to Telnet 2.3, which is now using MacTCP 1.01. I am using a LocalTalk connection to a Kinetics FastPath IV rev J. I have not yet upgraded these units for Phase 2 AppleTalk yet. Every time I try to transfer a file using FTP from my Sun system to the Macintosh, it hangs my machine.

The other new error happens when I am doing a Telnet session--I get NCSA Telnet error #1, program unexpectedly quit. It is independent of CPU (I am using system 6.0.5 on all systems). The problem showed up when I upgraded to Telnet 2.3. Have you heard of any problems like this one?
We haven't heard any problem like this. There are two versions of NCSA Telnet 2.3, one is Telnet without MacTCP, the other is Telnet with MacTCP. Here are some things to check:

* Make sure you're using the right version of NCSA Telnet 2.3. In this case, you must use NCSA Telnet 2.3 with MacTCP.

* Was MacTCP driver installed and configured properly?

* Was Kinetics FastPath software installed and configured properly?

* Try running "MacTCP Spy" from the Macintosh OS to see if MacTCP is up and running.

* From the Sun machine, try to use "ping", a generic UNIX network utility, to send an ICMP packet to the Macintosh machine to make sure they are talking to each other.

* Try to increase the NCSA Telnet 2.3 with MacTCP application memory size. This is done via Get Info.
