This patch is from Daniel Miller. He writes:
I've just finished enhancing the nfs-ls, nfs-statfs, and nfs-showmount
scripts so that they can run based on version detection information,
for cases where the portmapper is firewalled. For nfs-ls and
nfs-statfs, this required making a hostrule to check that both a
mountd service and a nfs service were detected. In the process, I
ended up adding the AUTH_UNIX flavor to rpc.lua, since the RFC states
that AUTH_NULL can only be used for the NULL procedure (and my Linux
nfs-kernel-server was enforcing that).
Other minor changes:
* If running privileged, attempt to bind to a reserved port. Many NFS
servers refuse to talk to source ports >1024, as a "security measure"
* handle an odd case in nfs-ls where READDIRPLUS does not return file
attributes. Chose to use all ?'s, but in the future maybe a direct
GETATTR call?
* remove reference to nfs.dirlist argument from nfs-ls doc, since it is unused
before) each group of tab.add, and there is no tab.nextrow before or
after tab.addrow. Also remove manual indenting that was accomplished by
padding the first column with spaces; this is done by
stdnse.format_output now.
nfs-showmount scripts to use the new library. The new scripts are:
- nfs-acls shows the owner and directory mode of NFS exports
- nfs-dirlist lists the contents of NFS exports
- nfs-statfs shows file system statistics for NFS exports
