iSCSI is an IETF standard (RFC 3720) for remote access to block-level storage. It can be thought of as similar to NFS, except that an NFS server exports files; the iSCSI target exports blocks to the iSCSI initiators, which are the clients. To set up the target, you need to edit the /etc/iscsi/targets file. It has a certain layout, to provide a means of (a) mirroring and (b) combining multiple areas to present one large contiguous area of storage. This can be multiply-layered.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
