You need to uncomment the line

	#ddns-update-style	ad-hoc;

in /etc/mol/dhcpd-mol.conf if you are using a recent dhcpd
version.

What do you mean by vanished... does the network device
show up in the control panel? What does the MOL log show?
Does 'dmesg' in OSX say something interesting?

The MOL-install disk is only mounted when MOL detects that
the network driver or the audio driver is not up-to-date
(or installed at all). (Btw. one can force it to always
be mounted by adding 'mount_mol_disk: always').

Odd... I would guess it doesn't have anything with the MolEnet
extension but rather with the linux side tun configuration.

For instance, if the dhcpd server is not stopped, then tun
device will be busy when MOL tries to open it the next
time.

Thanks... I've changed the regexp to

    IFACES=`netstat -i | sed -n -e 's/^\(tun[0-9]\).*/\1/gp'`

The original regexp depends upon the matching order (which apparently
is not always left-to-right).
