Example: QNX 4 – QNX 6 Communication via NULL-modem cable, PPP, NFS

This message does not require any answer – may be some QNX 6 users who, like
myself, are new to TCP/IP will find the example useful.


QNX 6 /etc/hosts

Host Database

127.1 localhost.localdomain localhost
::1 localhost.localdomain localhost
192.9.200.1 node1
192.9.200.3 node3

QNX 4 /etc/hosts

Host Database

127.1 localhost localhost.my.domain

192.9.200.1 node1
192.9.200.3 node3

QNX 4 /etc/exports

just one record with a slash

/




To start PPP on QNX 4 side, type:

#stty baud=115200 bits=8 stopb=1 par=none +raw < /dev/ser1
#Socket –p1 node1 &
#pppd /dev/ser1

To start PPP on QNX 6 side, type:

#stty baud=115200 bits=8 stopb=1 par=none +raw < /dev/ser2
#pppd /dev/ser2 192.9.200.3: 192.9.200.1

Now you can ping :

#ping node1

To start NFS server on QNX 4 box, type:
#portmap
#nfsd –u 0,0
#mountd –n

To start NFS client on QNX 6 side, type:
#fs-nfs2
and finally,
#mount –t nfs node1:/ /qnx4
