jetsend-contact-ip-address-security OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(16))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"A C structure containing the following fields:
typedef struct {
ubyte reserved[3];
ubyte command; /* command: 0 to 1 */
ubyte password[8];
ubyte IPAddress[4];
} jetsend_contact_ip_address_security_t;
where ubyte is an unsigned byte (0-255). The defined
values defined for command are:
When command is 0:
IPAddress is 0: device is locked, no one can contact
it
IPAddress is > 0: only that address is allowed to
contact the device
When command is 1:
IPAddress is 0: any device can contact it
IPAddress is > 0: any device matching this mask can
contact it. If the result of logically anding the mask
value supplied in the IPAddress field with the sending
device's IP address matches the result of logically
anding the mask value supplied in the IPAddress field
with this device's IP address, then JetSend will allow
the session to be established.
Additional information:
Controls the device or class of device(s) which may
communicate with the JetSend processing subsystem. The following C
data structure contains the relevant fields (described in subsequent
paragraphs):
typedef struct {
unsigned char reserved[3];
unsigned char command;
unsigned char password[8];
unsigned char IPAddress[4];}
The 'reserved' field is not used and should remain zero-filled.
The 'command' field interpretation differs based on its value:
0 = Accept session(s) only from the specific device whose
IP address matches the specified IP address; all other
session request(s) from non-matching device(s) are rejected.
1 = Accept session(s) only from the specific device(s) whose
IP address(es) conform to the mask specified in the 'IPAddress'
field; all other session request(s) from device(s) with
non-matching submask(s) are rejected. (If the result of
logically AND'ing the mask value supplied in the 'IPAddress'
field with the sending device's IP address matches the result
of logically AND'ing the mask value supplied in the 'IPAddress'
field with this device's IP address, then JetSend will allow
session establishment.
Password absence/presence determines whether the device will allow
the caller to alter the IP address security. If the password is
disabled, the caller may set the 'command' and 'IPAddress' fields
directly. If the password is enabled, the caller may (re-)set the
'command' and 'IPAddress' fields only after specifying the matching
'password' field. (Refer to the aforementioned 'JETSEND-CONTACT-PASSWORD'
object ID.)
(Specifying either an invalid 'command' field value or a 'password'
field greater than eight (8) bytes or an 'IPAddress' field greater
than four (4) bytes causes the error <badValue>
to be returned.)
This object will be enabled in IR devices even if is does not
detect an EIO card."
