Subject: [NFS] Patch to mountd to mount files > 2GB
Date: Tue, 13 Jan 2004 21:19:16 -0800

Greetings all,

If this has been problem/solution has been posted before, please disregard
:)

I'm using NFS to serve out FLAR archives to Sun machines.  These files are >
2GB, and the auto-installer for the Sun boxes mount the files, not the
directories.  mountd was refusing to authenticate these otherwise legit
requests because the stat() call was bombing due the filesize being too
large.  I hacked up the quick diff below that fixed the problem.  The files
transfer correctly and completely, but I admit I haven't performed further
testing.
