>Release: FreeBSD 3.0.0-current i386
>Environment:
FreeBSD 3.0 changes the type of the sockaddr needed to request
a link-layer multicast address. FreeBSD 3.0 has changed this so
that it is incompatible with other systems and FreeBSD 2.2.
>Description:
Netatalk cannot do correct zone manipulations with multicast
addressing.
>How-To-Repeat:
start netatlk.. watch atalk log files for:
atalkd[340]: addmulti: Invalid argument
>Fix:
The following patch needs to be incorporated into
the netatalk port.
