NFS export as readonly

[Jerome D'silva]

Host A has exported the files system as r/w to Host B .That means except Host B, all the other hosts have readonly access to this file system .
Can you let me know how we can prevent other than Host B from accessing this file system

[Pete Randall · Accepted solution]

How about the access= option of export? See man exportfs.

On HostA:

vi /etc/exports

and add your line in:
/dir ???root=HostB

save that and now run:

[HostA:/]# /usr/sbin/exportfs ???av

Hi,

In /etc/exports file of host A

/ -rw=hostB

this prevents other hosts from accessing the file syetm

Hi,

On server add

#vi /etc/exports

/tmp -anon=65534,ro

#exportfs -a

On client

#mount servername:/tmp /mnt

#cd /mnt

#bdf .

servername:/tmp 255253 9045 220682 4% /mnt

#touch file
touch: file cannot create

Regards,

Robert-Jan.

Hi
Thanks for all the suggestions . It is working now .The /etc/exports looks like this

/home -rw=HostB,access=HostB

This would allow only the HostB to mount and rw the file system .If we need ro for another host we can add this to the access list as well

Thanks
