Unable to start NFS server from FreeBSD Jail environment.

[Prashant Sarma]

Hi everybody,

I am relatively new to FreeBSD, so please pardon me
if this question is not appropriate for this mailing
list. My question pertains to FreeBSD jail
environments.

I am unable start an NFS server from within a 
FreeBSD jail. I have configured the jail environment
to allow sshd and telnet, but I am unable to export
file systems from the jail.

My logs and configuration are as follows:

/var/log/messages (Jail Environment):

Oct 31 09:36:00 emulite2 mountd[210]: can't delete
exports for /
Oct 31 09:36:00 emulite2 mountd[210]: can't delete

Oct 31 09:36:00 emulite2 nfsiod:[238]: nfssvc:
Operation not permitted

CONFIGURATION:

Parent Machine: Pentium 1.5 GHz., 3Com (xl0) 10/100
interface, FreeBSD 4.8-RELEASE

Jail Environment: Runs on an independent hard disk,
mounted by the Parent, has network connectivity
(network interface is aliased from Parent's
interface),
successfully runs sshd. 

Here is an 'rpcinfo -p' done on the jail:

    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100005    3   udp   1008  mountd
    100005    3   tcp   1021  mountd
    100005    1   udp   1008  mountd
    100005    1   tcp   1021  mountd
    100003    2   udp   2049  nfs
    100003    3   udp   2049  nfs
    100024    1   udp    998  status
    100024    1   tcp   1020  status

Here is the Jail's  /etc/exports file:
/usr	-alldirs			leaningtower

I would would appreciate any advice/pointers in this 
regard.

Thank you,

Prashant
