[Nbd] authfile syntax

[Richard Huddleston <rhuddusa@...17...>]

i'm trying to get the nbd-server 1:2.9.14-2ubuntu1 authfile to work
under ubuntu lucid

it's correctly parsing

192.168.2.101
192.168.2.103
192.168.2.104
192.168.2.105


but fails to parse

192.168.2.0/24

and during a connection attempt nbd-server outputs

Invalid entry '192.168.2.0' in authfile '/etc/nbd-server/allow', so,
refusing all connections.

what gives?

in addition, i'm confused by

http://linux.die.net/man/5/nbd-server

With /etc/nbd-server/allow containing the following:

127.0.0.1
192.168.0.0/8
192.168.1.1

does 192.168.0.0/8 make sense?

shouldn't it be either

192.0.0.0/8

or

192.168.0.0/16

?
