Re: doubts on NFS
I was told by a little bird on this list to set the -root=0 option,
maybe little bird meant -maproot=0 :)
And yes, i HUPed.
But it's all working now, the magic was to add the missing line to fstab.
Thanks everybody for your tips and help on this

Re: doubts on NFS
Sorry, the 10.10.10.101 was a mistyping of mine. It's another IP i used
to try mounting the slice from.
I removed it and not HUPed mountd, that's why it showed up with showmount.
This are the permissions you just asked:
backup:~{2}# cd /u/data/
backup:/u/data{3}# ls a-l|grep export
ls: a-l: No such file or directory
backup:/u/data{4}# ls -al|grep export
drwxr-xr-x 2 root wheel 512 Jul 6 21:29 export/
backup:/u/data{5}#

Why is this different from what the server actually exports?
Namely, how did 10.10.10.101 get in here?

What are the permissions of /u/data/export on the server?

There is no such option. Do you mean maproot?
Did you HUP mountd after you changed the config file?

I;ve just solved it . Adding this the line to /etc/fstab on the client
machine just let me mount it and write on it.
I had no need to reboot or restart anything.

Re: doubts on NFS
Edd ,
This are the permissions:
hq:/{19}# ls -al |grep mnt
drwxr-xr-x 2 root wheel 512 Nov 3 2008 mnt/
hq:/{20}#
I am mounting this as root .
I also added -root=0 to /etc/exports , still same behavior

What's your protection on the mount point of the /u/data/export directory
*before* mounting the slice on it? It's not the same protection mask before
and after...

doubts on NFS
Hello list ,
I am having trouble to make NFS work properly. I don't know what i am
doing wrong, maybe
someone can enlighten me.
NFS server and client are both OpenBSD 4.4 GENERIC
I am starting portmap, nfsd and mountd on the nfs server (10.10.10.65).
This is my /etc/exports on 10.10.10.65:
# $OpenBSD: exports,v 1.2 2002/05/31 08:15:44 pjanzen Exp $
#

# of this file can result in your filesystems being readable by the world.
/u/data/export -alldirs -maproot=0 10.10.10.16

On the client machine (10.10.10.16) :
hq:/{190}# showmount -e 10.10.10.65

What am i doing wrong here?
Thanks in advance for your help
