After I installed the QNX 6.2, I found the TCP/IP is not configured. I set the IP 18.104.22.168, mask 255.255.240.0, and I can ping my self by pinging 127.0.0.1, or 22.214.171.124. However, I cannot ping any other machine in the same subnet, like 126.96.36.199. Neither can other machine ping this QNX machine.
The net cmd is set to:
set(IONET-CMD io-net -pttcpip)
I attempted to slay the io-net but don’t know how to reload the driver,
since I don’t know which driver corresponds to the NIC I use (D-link).
I’ll try with another NIC, maybe Realtek 8139, which is always
successful with my previous configuration. But the weird thing is that
this NIC is recognized by the QNX, and IO-NET is also started. Only the
TCP/IP with other machine is problematic. The phycial error can be
excluded, because under Windows, all the machines can communicate with
