Is there something trivial that I am doing wrong here? My
understanding is freebsd can mount Netware 5.0 volumes via IP (using
the mount_nwfs command you just have to be sure to use the -A flag)
and not have to rely on IPX like previous versions of Netware (less
than 5). Please correct me if any of that is incorrect.
