ISCSI.CONF(5) BSD File Formats Manual ISCSI.CONF(5) NAME
iscsi.conf -- iSCSI initiator configuration file DESCRIPTION
The file iscsi.conf, is used by the iscsictl(8) and iscontrol(8) utilities. It contains declarations and parameter/key-options. The syntax is very simple, variable = value; and they can be grouped via a block declaration: # this is a comment target_1 { # nickname variable = value; ... } # this must be on a line by itself. The following are specified in the iSCSI RFC 3720, for a full description see sections 11/12 of the RFC. AuthMethod currently only supported authentication method is CHAP, with digest either MD5 or SHA. Default is none. HeaderDigest a digest is calculated on the header of all iSCSI PDUs, and checked. Only CRC32C is implemented. Default is none. DataDigest same as for HeaderDigest, but on the data part of the iSCSI PDU. (not yet tested) TargetName is the name by which the target is known, not to be confused with target address, either obtained via the target administra- tor, or from a discovery session. InitiatorName if not specified, defaults to iqn.2005-01.il.ac.huji.cs: <hostname>. TargetAddress is of the form domainname[:port][,portal-group-tag] to quote the RFC: The domainname can be specified as either a DNS host name, a dotted-decimal IPv4 address, or a bracketed IPv6 address as specified in [RFC2732]. Note: portal-group-tag is unused at the moment. not implemented yet. MaxRecvDataSegmentLength the maximum data segment length in bytes it can receive in an iSCSI PDU, default is 8192. MaxOutstandingR2T is used to calculate/negotiate the tag opening, can be overridden by the tag option. SessionType either Discovery or Normal, default is Normal, see the -d flag of iscontrol. The following are not specified in the RFC 3720 offload Name of selected iSCSI hardware offload driver. port The iSCSI port used by the iSCSI protocol, defaults to 3260. tags Sets the tag opening to the value specified. maxluns overrides the compiled value of luns, see iscsi_initiator(4). This value can only be reduced. sockbufsize sets the receiver and transmitter socket buffer size to size, in kilobytes. The default is 128. If AuthMethod is set to CHAP, then the following must also be set: chapSecret this shared-secret. Can be either an ASCII string (e.g. hello world), a hex string (e.g 0xababcd0987654321...), or base64 string (eg 0b...) chapIName the chap-name, defaults to hostname. chapDigest can be MD5 or SHA1. tgtChapName/tgtChapSecret name and secret used for mutual CHAP; by default, mutual CHAP is not used.

ISCSI RFC 3720 BUGS
Some options have not been implemented, either they were found to be unnecessary, or not understood, this can change in the future. The tags opening value is difficult to calculate, use wisely. BSD
