First I am going to test phditto using two QNX 6 machines. Later on I will use QNX 6-to-4 access combination. In any case we will have to use TCP/IP since our QNX 4 machines will be located in remote places.
I could not manage to talk two QNX 6 (One is on Vmware and the other has booted up using the live dvd. Tested bidirectionally -from vmware to live dvd, and live dvd to vmware.) I was not even able to remote access neither my winXP nor linux machines. In the other method, since it is necessary to make a change in inetd.conf (live dvd boot - files are read-only) file I could not succeed in this step, too.
My next attempt is to create one hard QNX 6 installation which later we will use a host to access our QNX 4 platform.
