Re: [OmniOS-discuss] NFS mounts seems as nobody on Centos6

2017-06-15 Thread Linda Kateley 

this might not answer your question but..

anon=root means that any user that tries to mount that is unknown to the 
server will be treated as if they are root and root from another system 
will be given the permission of nobody.. what you want is 
root=someuser.. In nfs root from another system is almost always seen as 
hostile by default.

Hi Özkan,

The first thing that comes to mind is "no_root_squash" and, based
on your example setting with options like "anon=root", I assume
this option can be set as well on OmniOS with the "sharenfs" setting.

Maybe these will help:

Disclaimer: I am not an expert on NFS! Far from it. The above
suggestion is based on some personal experience where I needed
that "no_root_squash" option (although that was with some Linux
distro's), and some Google-fu. With that said, I am not sure if it
adds a security threat or something.

Anyway, my two cents.

Hi Özkan,

The first thing that comes to mind is "no_root_squash" and, based on 
your example setting with options like "anon=root", I assume this option 
can be set as well on OmniOS with the "sharenfs" setting.
