I apologize for a repeat question, but I did not do due diligence last time.
The network install process of MP-RAS uses NFS. However, it seems to be an older version than when the system is actually up and running. I believe what I am seeing is NFS version 2 during the install process, and version 3 when fully up.
I have no difficulty mounting from FC2->MP-RAS except during a network install.
My observations may be incorrect, but...
During network install they use NFS version 2 and try to authenticate with a user: NCR_NETINSTALL
NFS version 2 would normally require root, or none. There is a blurb in their man pages for network based installs that says you need to use the -n option to mountd to be able to do this successfully. Well the -n option for old SYSV systems is:
With the -n option, mountd does not check that the clients
are root users. Though this option makes things slightly
less secure, it does allow older versions (pre-3.0) of
client NFS to work.No equivalent option is apparent to me from the FC2 mountd man pages.
So the obvious questions are: Why does HPUX nfs work? Why does FC2 nfs NOT work? Is there a way to make FC2 work?
I have some small packet captures if anyone would like me to email them to you. I have FC2 failing on two attempts (8 packets, 4 of which are summarized below) and a successful mount to HPUX 11i (37 packets).
Here are the packets dumped during the attempt to mount from FC2, and you can see that packet 4 is a denial.
