>Release: FreeBSD 3.0-BETA i386
>Environment:
FreeBSD NFS server in a Solaris 2.5, 2.51, and 2.6 environment.
>Description:
The Solaris 2.6 system trying to automount using the /net
mechanism will refuse negotiate down to nfs version 2
if it finds version 3 registered with the portmaper.
Mountd is running and only allowing version 2 mounts.
I believe BETA 3.0 is known to have NFS version 3 problems.
>How-To-Repeat:
Have a default 3.0 BETA system with exported filesystems
login to a Solaris 2.6 system and try to list one of
the exported directories. Note the failure.
Also note that 3.0 BETA will reliably crash while an NFS
version 3 client is doing a tar extract.
>Fix:
Allow nfsd to have a -2 option as well.
The following diff could be applied to
/usr/src/sbin/nfsd.c
And -2 added to the nfsd options in the rc.conf script.
