     iscsi.conf — key options to be negotiated in an iSCSI session

     The file iscsi.conf, is read by the iscontrol(8) program.	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

     DataDigest	     same as for HeaderDigest, but on the data part of the
		     iSCSI PDU.	 (not yet tested)

     MaxConnections  is the number of simultaneous connections per session,
		     currently only 1.

     TargetName	     is the name by which the target is known, not to be con‐
		     fused with target address, either obtained via the target
		     administrator, or from a discovery session.

     InitiatorName   if not specified, defaults to

     TargetAlias / InitiatorAlias
		     not implemented.

     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.

     InitialR2T	     not implemented yet.

     ImmediateData   not implemented yet.

		     the maximum data segment length in bytes it can receive
		     in an iSCSI PDU, default is 8192.

     MaxBurstLength  not implemented yet.

		     not implemented yet.

		     not implemented yet.

		     not implemented yet.

		     is used to calculate/negotiate the tag opening, can be
		     overriden by the tag option.

     DataPDUInOrder  not implemented yet.

		     not implemented yet.

		     Only level 0 is supported.

     SessionType     either Discovery or Normal, default is Normal, see the -d
		     flag of iscontrol.

     The following are not specified in the RFC 3720

     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.

		 same as the none tgt counterpart, but to authenticate the


     # Globals
     port = 3260
     myiscsi { # nickname
	targetaddress	     = iscsi1
	targetname	     =
     chaptest {
	targetname   =
	authmethod = CHAP; chapDigest = SHA1;
	chapsecret = 0x3713c3336d9a224c2791c873d3d2b174
	tags	     = 256

     The parsing is very primitive, so do not expect - at the moment - any
     error messages.

     iscsi_initiator(4), iscontrol(8)

     ISCSI RFC 3720

     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.
