ISCSI-TARGET(8) BSD System Manager's Manual ISCSI-TARGET(8) NAME
iscsi-target -- service remote iSCSI requests SYNOPSIS
iscsi-target [-46DV] [-b block length] [-f configuration file] [-p port number] [-s maximum number of sessions] [-t target name] [-v verbose arg] DESCRIPTION
iscsi-target is the server for iSCSI requests from iSCSI initiators. iscsi-target listens for discovery and login requests on the required port, and responds to those requests appropriately. Options and operands available for iscsi-target: -4 iscsi-target will listen for IPv4 connections, and respond back using IPv4. This is the default address family. -6 iscsi-target will listen for IPv6 connections, and respond back using IPv6. -b blocksize Specify the underlying block size for iSCSI storage which will be served. The possible sizes are: 512, 1024, 2048, and 4096 bytes, with the default being 512 bytes. -D When this option is specified, iscsi-target will not detach itself from the controlling tty, and will not become a daemon. This can be useful for debugging purposes. -f configfile Use the named file as the configuration file. The default file can be found in /etc/iscsi/targets. See targets(5) for more informa- tion. -p port number Use the port number provided as the argument as the port on which to listen for iSCSI service requests from initiators. -s maximum number of sessions Allow the maximum number of sessions to be initiated when connecting to the target. -t filename The target name (as it appears to the iSCSI initiator) can be specified using this flag. -V iscsi-target will print the utility name and version number, and the address for bug reports, and then exit. -v argument The amount of information shown can be varied by using this command. Possible values of argument are net to show network-related information, iscsi to show iSCSI protocol-related information, scsi to show SCSI protocol information, and all to show information from all of the above arguments.

ISCSI-INITIATOR(8) BSD System Manager's Manual ISCSI-INITIATOR(8) NAME
iscsi-initiator -- refuse-based iSCSI initiator SYNOPSIS
iscsi-initiator [-46bcDfVv] [-a authentication-type] [-d digest-type] [-h target-hostname] [-p target-port-number] [-t target-number] [-u username] mount_point DESCRIPTION
The iscsi-initiator utility can be used to access an iSCSI target, such as iscsi-target(8), to access block storage which has been exported. Information pertaining to the target is displayed underneath the mount point, along with the device corresponding to the storage which the target exports. The various arguments are as follows: -4 Use an IPv4 connection to the target. -6 Use an IPv6 connection to the target. -a authentication-type Use the specified authentication type when communicating with the target. The possible values are chap, kerberos, srp or none. The default value is none. -b Show the storage as a block device. -c Show the storage as a character device. -d digest-type Use the specified digest type when communicating with the target. The possible values are header, data, both, all or none. The default value is none. -D List the LUNs on the specified target and exit (i.e. do discovery only) -f Show the storage as a regular file. -h hostname Connect to the iSCSI target running on the host specified as the argument. -p port-number Connect to the iSCSI target running on the port specified as the argument. The default value is 3260. -t target Connect to the number of the iSCSI target running as the argument. -u username Use the specified user's credentials when logging in to the iSCSI target. There is no default. -V Print out the version number and then exit. -v Be verbose in operation. The refuse(3) library is used to provide the file system features. The mandatory parameter is the local mount point. This iSCSI initiator presents a view of the targets underneath the mount point. Firstly, it creates a directory tree with the hostname of the target, and, in that directory, a virtual directory is created for each target name exported by the iSCSI target program. Within that virtual target directory, symbolic links exist for the hostname (for convenience), a textual representation of the IP address, the iSCSI tar- get product name, the iSCSI target IQN, the iSCSI target vendor and version number. One other directory entry is presented in the virtual target directory, relating to the storage presented by the iSCSI target. This can be in the form of a regular file, which is also the default, a block device or a character device. Please note that the iscsi-initiator utility needs the ``puffs'' kernel module loaded via modload(8) to operate. EXAMPLES

puffs(3), refuse(3), iscsi-target(8) HISTORY
The iscsi-initiator utility first appeared in NetBSD 6.0. An earlier version called iscsifs was available in NetBSD 5.0 in source format only. AUTHORS
The iscsi-initiator utility was written by Alistair Crooks <agc@NetBSD.org>. BUGS
iscsi-initiator currently only supports a CHAP challenge length of 16 octets. Other initiators support up to 1024 and thus it is expected that most targets will also support such lengths. This means that CHAP compatibility with other targets apart from iscsi-target(8) is likely to be poor. To workaround this, please use authentication type none by not specifying a username with the -u option. BSD
