NFS can be tricky because it uses the same permissions as your local drive. Someone with UID=1000 and GID=1000 saves a file, with permissions 770, on an NFS share. Only those with the same UID or GID can read/write the file.

I use NFS for all of my desktop computers, but I have a laptop that runs Vista Ultimate. With Vista Ultimate (and Windows XP), you can install Services for Unix, which includes support for NFS. My problem is that Vista and XP seem to send UID and GID as -2. I can’t figure out how to change them. Anyone have any suggestions?
-----------------------

I use ldap as a central authentication like DC (include uid/gid attributes) on NFS Server. Use pam-ldap for an other authentication method from linux client: log-in, get uid/gid from ldap, access to NFS.

Use pGina (http://www.pgina.org) for an other authentication method from Windows platform to ldap: log-in, get uid/gid from ldap, access to NFS.

Is it enough for you?


/files 192.168.1.1/24(rw,no_root_squash,async)


is insanely insecure… As long as you never have / shared like this it’s ok, but no_root_squash is generally a Bad Idea.

2)In altering the /etc/fstab file I needed to add
0 0
to the end of the line so it read
server.mydomain.com:/files /files nfs rsize=8192,wsize=8192,timeo=14,intr 0 0
Found that here. Thanks

This is an informational message, not an error. Add the “subtree_check” option to each of your entries in /etc/exports; for example, (rw,no_root_squash,async,subtree_check). The message will disappear. As it stands, your NFS should be operational with or without this option in /etc/exportfs.

Robert.

My NFS mounts show up in /proc/mounts though.

Any information on this topic would be greatly appreciated (even more if sent to ubuntugeek#alfe.de (replace the # by a @))

Thanks!

my /etc/exports file has this line only:
/media/hdb1/DVArchive_files/Local_Guide 192.168.1.1/24(rw,no_root_squash,async)

When I run sudo exportfs -a I get this error
exportfs: /etc/exports [1]: Neither ’subtree_check’ or ‘no_subtree_check’ specified for export “192.168.1.1/24:/media/hdb1/DVArchive_files/Local_Guide”.
Assuming default behaviour (’subtree_check’).
Note: this default will change with nfs-utils version 1.1.0

Any idea what does this mean.
Also can you please direct me to instruction on how to set nfs on Vista?

Thanks
Sam

if i mount one additional directory manually from the server, the mount - comamand shows it up as i would expect it.

does anybody know, what is went wrong?

How to make my Ubuntu give permission (on the fly) 660 every new file created by user on share folder. N change the group owner as group “finance” as example.

Any solusion with this? Cause with samba i can use this option:
create mask = 0660
directory mask = 0770
force group = finance

@zukakog:
simply change file access permissions to any data written from the NFS mounts in Linux, as windows requires WORLD READ/WORLD WRITE

sudo chmod -R 0777 /home/czar/my_nas_share_folder/

Now pop back to Windows and feel the insecurity.

Nice tutorial by the way. Most people are surprised at how simple NFS, usually after going through SAMBA configuration dance.

# John: you can’t edit a document opened by another user because is locked, but you can edit it ‘after it is closed’ just taking in account file’s permissions.
