I’m experiencing a very bizarre problem. I have a QNX machine with 6 Ethernet ports. I set the Ethernet ports in my rc.local file. After some time elapses, the IP address will change without warning. I shouldn’t say that it chooses a random IP address, as it seems to like 172.16.0.244, but it sometimes chooses a different value. This intermittent problem has been causing me a lot of grief and I’d appreciate any suggestions for debugging this issue.
I also have 3 other QNX machines configured identically, but I’m only experiencing this problem with one of the machines. Is there anything I can do besides reinstall QNX on the problematic machine?
