33.Sh NAME
34.Nm ctl.conf
35.Nd CAM Target Layer / iSCSI target daemon configuration file
36.Sh DESCRIPTION
37The
38.Nm
39configuration file is used by the
40.Xr ctld 8
41daemon.
42Lines starting with
43.Ql #
44and empty lines are interpreted as comments.
45The general syntax of the
46.Nm
47file is:
48.Bd -literal -offset indent

58 listen-iser <address>
59 discovery-auth-group <name>
60 ...
61}
62
63target <name> {
64 auth-group <name>
65 portal-group <name>
66 lun <number> {

71.Ed
72.Ss global level
73The following statements are available at the global level:
74.Bl -tag -width indent
75.It Ic auth-group Aq Ar name
76Opens an auth-group section, defining an authentication group,
77which can then be assigned to any number of targets.
78.It Ic debug Aq Ar level
79Specifies debug level.
80The default is 0.
81.It Ic maxproc Aq Ar number
82Specifies limit for concurrently running child processes handling
83incoming connections.
84The default is 30.
85Setting it to 0 disables the limit.
86.It Ic pidfile Aq Ar path
87Specifies path to pidfile.
88The default is
89.Pa /var/run/ctld.pid .
90.It Ic portal-group Aq Ar name
91Opens a portal-group section, defining a portal group,
92which can then be assigned to any number of targets.
93.It Ic target Aq Ar name
94Opens a target configuration section.
95.It Ic timeout Aq Ar seconds
96Specifies timeout for login session, after which the connection
97will be forcibly terminated.
98The default is 60.
99Setting it to 0 disables the timeout.
100.El
101.Ss auth-group level
102The following statements are available at the auth-group level:
103.Bl -tag -width indent
|
104.It Ic auth-type Ao Ar type Ac
105Specifies authentication type.
106Type can be either "none", "chap", or "chap-mutual".
107In most cases it is not neccessary to set the type using this clause;
108it is usually used to disable authentication for a given auth-group. |
109.It Ic chap Ao Ar user Ac Aq Ar secret
110Specifies CHAP authentication credentials.
111.It Ic chap-mutual Ao Ar user Ac Ao Ar secret Ac Ao Ar mutualuser Ac Aq Ar mutualsecret
112Specifies mutual CHAP authentication credentials.
113Note that for any auth-group, configuration may contain either chap,
114or chap-mutual entries; it's an error to mix them.
115.It Ic initiator-name Ao Ar initiator-name Ac
116Specifies iSCSI initiator name.
117If not defined, there will be no restrictions based on initiator
118name.
119Otherwise, only initiators with names matching one of defined
120ones will be allowed to connect.
121.It Ic initiator-portal Ao Ar address Ac
122Specifies iSCSI initiator portal - IPv4 or IPv6 address.
123If not defined, there will be no restrictions based on initiator
124address.
125Otherwise, only initiators with addresses matching one of defined
126ones will be allowed to connect.
127.El
128.Ss portal-group level
129The following statements are available at the portal-group level:
130.Bl -tag -width indent
131.It Ic discovery-auth-group Aq Ar name
132Assigns previously defined authentication group to that portal group,
133to be used for target discovery.
134By default, the discovery will be denied.
135A special auth-group, "no-authentication", may be used to allow for discovery
136without authentication.
137.It Ic listen Aq Ar address
138Specifies IPv4 or IPv6 address and port to listen on for incoming connections.
139.It Ic listen-iser Aq Ar address
140Specifies IPv4 or IPv6 address and port to listen on for incoming connections
141using iSER (iSCSI over RDMA) protocol.
142.El
143.Ss target level:
144The following statements are available at the target level:
145.Bl -tag -width indent
146.It Ic alias Aq Ar text
147Assigns human-readable description to that target.
148There is no default.
149.It Ic auth-group Aq Ar name
150Assigns previously defined authentication group to that target.
151There is no default; every target must use either auth-group,
152or chap, or chap-mutual statements.
153A special auth-group, "no-authentication", may be used to permit access
154without authentication.
|
155.It Ic auth-type Ao Ar type Ac
156Specifies authentication type.
157Type can be either "none", "chap", or "chap-mutual".
158In most cases it is not neccessary to set the type using this clause;
159it is usually used to disable authentication for a given target.
160This clause is mutually exclusive with auth-group; one cannot use
161both in a single target. |
162.It Ic chap Ao Ar user Ac Aq Ar secret
163Specifies CHAP authentication credentials.
164Note that targets must use either auth-group, or chap,
165or chap-mutual clauses; it's a configuration error to mix them in one target.
166.It Ic chap-mutual Ao Ar user Ac Ao Ar secret Ac Ao Ar mutualuser Ac Aq Ar mutualsecret
167Specifies mutual CHAP authentication credentials.
168Note that targets must use either auth-group, chap, or
169chap-mutual clauses; it's a configuration error to mix them in one target.
170.It Ic initiator-name Ao Ar initiator-name Ac
171Specifies iSCSI initiator name.
172If not defined, there will be no restrictions based on initiator
173name.
174Otherwise, only initiators with names matching one of defined
175ones will be allowed to connect.
176This clause is mutually exclusive with auth-group; one cannot use
177both in a single target.
178.It Ic initiator-portal Ao Ar address Ac
179Specifies iSCSI initiator portal - IPv4 or IPv6 address.
180If not defined, there will be no restrictions based on initiator
181address.
182Otherwise, only initiators with addresses matching one of defined
183ones will be allowed to connect.
184This clause is mutually exclusive with auth-group; one cannot use
185both in a single target.
186.It Ic portal-group Aq Ar name
187Assigns previously defined portal group to that target.
188Default portal group is "default", which makes the target available
189on TCP port 3260 on all configured IPv4 and IPv6 addresses.
190.It Ic lun Aq Ar number
191Opens a lun configuration section, defining LUN exported by a target.
192.El
193.Ss lun level
194The following statements are available at the lun level:
195.Bl -tag -width indent
196.It Ic backend Ao Ar block | Ar ramdisk Ac
197Specifies the CTL backend to use for a given LUN.
198Valid choices are
199.Dq block
200and
201.Dq ramdisk ;
202block is used for LUNs backed
203by files in the filesystem; ramdisk is a bitsink device, used mostly for
204testing.
205The default backend is block.
206.It Ic blocksize Aq Ar size
207Specifies blocksize visible to the initiator.
208The default blocksize is 512.
209.It Ic device-id Aq Ar string
210Specifies SCSI Device Identification string presented to the initiator.
211.It Ic option Ao Ar name Ac Aq Ar value
212Specifies CTL-specific options passed to the kernel.

217.It Ic size Aq Ar size
218Specifies LUN size, in bytes.
