Another option would be to port the FreeBSD NFS client to RTEMS. For this we need a FreeBSD kernel file system layer to RTEMS file system layer adaptor. > > - Till > On 06/10/2016 05:20 AM, Sebastian Huber wrote: >> Hello, >> >> I imported a snapshot of the standard RTEMS NFSv3 client from Till >> Straumann to the libbsd (the new network stack).

The RTEMS NFSv2 client does talk to our RHEL-7.3 server with the
configuration change I posted for Mark, but the VxWorks 5.4.2 NFS client
broke somewhere between the RHEL-7.2 and 7.3 servers. VxWorks 5.5 has an
NFSv3 client (which is buggy, make sure you get all the available
patches) that works OK against a RHEL-7.3 server.
The APS now only has *2* production IOCs left running on EPICS 3.13.10,
having upgraded the others to Base-3.14.12 and VxWorks 5.5 or 6.9. This
solved the NFSv2 issue for VxWorks, but our RTEMS-4.9.2 and 4.10.2
systems are still stuck with NFSv2...
