Hi boys. I’ve some security-related questions for you .
I’ve read the qnet chapter in the reference but I’ve not understand
if qnet effectively relyes on the IP protocol? Or simply uses
directly datagrams to communicate through the lines?
If it relyes on IP (or udp) what precautions I should take care of
if a qnx machine will be used as a http server over a tcp link?
(probably under ppp, maybe it offers some kind of security).
Should I put it behind a firewall? Which ports should I iron out?
Could the ipfilter package for io-net suffice?
Another one… every machine in a lan is avaible under /net.
Is the complete filesystem avaible? If so, what kind of security
have users of machine “a” if machine “b” can access every file on
it? Does Qnx prevents of having 2 identical users on 2 different machines
on the same lan?
How I could exclude a single machine for being resolved under /net
under my lan? Or could I exclude a single path (say /home) from being
I’m still confused. The network seems to not have any security!
Thanks in advance
