Strange nfs problem after update

[Christian Schlaefcke]

Hi Folks,

since I rebooted my machine after the latest updates I cannot mount the
nfs exports on that machine. When I try to mount I get an 'Permission
denied' error. The strange thing about this is that /var/log/messages
just says:

Mar 28 17:01:41 my_machine rpc.mountd: authenticated mount request from
my_client.de:978 for /usr/local/share (/usr/local/share)

This doesn´t look like an error? After some resaerch @ google I can say
that my /etc/exports, /etc/hosts, /etc/hosts.allow seem to be OK:

/etc/exports:
/usr/local/share        192.168.0.0/255.255.255.0(sync,rw)

/etc/hosts.allow:
tcp-env: 192.168.0.1/255.255.255.0, 192.168.0.2/255.255.255.0,
192.168.0.3/255.255.255.0: setenv = RELAYCLIENT
tcp-env: ALL

Are there any other logs available? What could cause this? I was also
researching for iptables issues. The problem occurs even with disabled
iptables (iptables -F).

Any help is appreciated!

Thanks & Regards,

Chris
